Abstract = {Respiration and photosynthesis of the planktonic foraminifera
Globigerinoides ruber, Orbulina universa, and Globigerinella siphonifera
and their symbiotic algae were calculated from measured dissolved oxygen
gradients using microelectrodes, using different temperatures in dark
and light (250 mu mol photon m(-2) s(-1)) conditions. At one temperature
(24 degrees C) the respiration rate increased as a power function of the
foraminiferan organic carbon mass with a 0.57 +/- 0.18 exponent. The
effect of temperature on respiration was quantified in two ways: by
normalizing the rates to the organic carbon mass and by normalizing the
observed rates to a constant temperature (24 degrees C). This latter
normalization was also used for photosynthesis. The respiration rates
increase as a function of temperature for all species and can be
described either with a Q(10) = 3.18 (+/- 0.27) or with an Arrhenius
temperature of T-A = 10,293 degrees K (+/- 768 degrees K). Similar
calculations for net photosynthesis yielded a Q(10) = 2.68 (+/- 0.36)
and a T-A = 8766uK (+/- 1203 degrees K), and calculations for gross
photosynthesis yielded a Q(10) = 2.76 (+/- 0.29) and a T-A = 9026
degrees K (+/- 926 degrees K). For the species studied, the
photosynthesis : respiration ratio varied from moderate for G.
siphonifera (0.58) to very high (13) for O. universa. The high ratios
indicate that photosynthesis is much higher than the carbon requirements
for both foraminifera and symbiont growth. This excess carbon might be
the source of organic exudates.},

Title = {Symbiont genotype influences holobiont response to increased temperature},
Journal = {SCIENTIFIC REPORTS},
Year = {2022},
Volume = {12},
Number = {1},
Month = {NOV 1},
Abstract = {As coral reefs face warming oceans and increased coral bleaching, a
whitening of the coral due to loss of microalgal endosymbionts, the
possibility of evolutionary rescue offers some hope for reef
persistence. In tightly linked mutualisms, evolutionary rescue may occur
through evolution of the host and/or endosymbionts. Many obligate
mutualisms are composed of relatively small, fast-growing symbionts with
greater potential to evolve on ecologically relevant time scales than
their relatively large, slower growing hosts. Numerous jellyfish species
harbor closely related endosymbiont taxa to other cnidarian species such
as coral, and are commonly used as a model system for investigating
cnidarian mutualisms. We examined the potential for adaptation of the
upside-down jellyfish Cassiopea xamachana to increased temperature via
evolution of its microalgal endosymbiont, Symbiodinium microadriaticum.
We quantified trait variation among five algal genotypes in response to
three temperatures (26 degrees C, 30 degrees C, and 32 degrees C) and
fitness of hosts infected with each genotype. All genotypes showed
positive growth rates at each temperature, but rates of respiration and
photosynthesis decreased with increased temperature. Responses varied
among genotypes but were unrelated to genetic similarity. The effect of
temperature on asexual reproduction and the timing of development in the
host also depended on the genotype of the symbiont. Natural selection
could favor different algal genotypes at different temperatures,
affecting host fitness. This eco-evolutionary interaction may be a
critical component of understanding species resilience in increasingly
stressful environments.},

Title = {Variable thermal stress tolerance of the reef-associated
symbiont-bearing foraminifera <i>Amphistegina</i> linked to differences
in symbiont type},

Abstract = {Adaptation, acclimatization and symbiont diversity are known to regulate
thermal tolerance in corals, but the role of these mechanisms remains
poorly constrained in other photosymbioses, such as large benthic
foraminifera (LBFs), which are known to bleach at temperatures that are
likely to be exceeded in the near future. LBFs inhabit a broad range of
shallow-water settings. Within species, differences in thermal tolerance
have been found among populations from different habitats, but it is not
clear whether such differences occur among LBFs inhabiting similar
habitats, but differing in other aspects, such as symbiont type. To this
end, we compared responses to thermal stress in specimens from a
population of Amphistegina lessonii, an abundant Indo-Pacific species,
to specimens of Amphistegina gibbosa, its Atlantic counter-part, from a
similar environment but two different water depths (5 and 18 m). Test
groups of each species were exposed in a common experiment to three
thermal stress scenarios over a four-week period. Growth, respiration,
mortality and motility were measured to characterize the holobiont
response. Coloration, photosynthesis and chlorophyll a content were
measured to determine the response of the endosymbiotic diatoms. The
photosymbionts were characterized by genetic fingerprinting. Our results
show that, although groups of A. gibbosa were collected from different
habitats, their responses were similar, indicating only marginally
higher tolerance to thermal peaks in specimens from the shallower site.
In contrast, species-specific differences were stronger, with A.
lessonii showing higher tolerance to episodic stress and less pronounced
impacts of chronic stress on motility, growth and photosymbiont
performance. These interspecies variations are consistent with the
presence of different and more diverse symbiont assemblages in A.
lessonii compared with A. gibbosa. This study demonstrates the
importance of considering symbiont diversity in the assessment of infra-
and interspecific variations in stress responses in LBFs.},

Title = {Effects of elevated temperature and <i>p</i>CO<sub>2</sub> on the
respiration, biomineralization and photophysiology of the giant clam
<i>Tridacna maxima</i>},
Journal = {CONSERVATION PHYSIOLOGY},

Abstract = {Many reef organisms, such as the giant clams, are confronted with global
change effects. Abnormally high seawater temperatures can lead to mass
bleaching events and subsequent mortality, while ocean acidification may
impact biomineralization processes. Despite its strong ecological and
socio-economic importance, its responses to these threats still need to
be explored. We investigated physiological responses of 4-year-old
Tridacna maxima to realistic levels of temperature (+1.5 degrees C) and
partial pressure of carbon dioxide (pCO(2)) (+800 mu atm of CO2)
predicted for 2100 in French Polynesian lagoons during the warmer
season. During a 65-day crossed-factorial experiment, individuals were
exposed to two temperatures (29.2 degrees C, 30.7 degrees C) and two
pCO(2) (430 mu atm, 1212 mu atm) conditions. The impact of each
environmental parameter and their potential synergetic effect were
evaluated based on respiration, biomineralization and photophysiology.
Kinetics of thermal and/or acidification stress were evaluated by
performing measurements at different times of exposure (29, 41, 53, 65
days). At 30.7 degrees C, the holobiont O-2 production, symbiont
photosynthetic yield and density were negatively impacted. High pCO(2)
had a significant negative effect on shell growth rate, symbiont
photosynthetic yield and density. No significant differences of the
shell microstructure were observed between control and experimental
conditions in the first 29 days; however, modifications (i.e.
less-cohesive lamellae) appeared from 41 days in all temperature and
pCO(2) conditions. No significant synergetic effect was found. Present
thermal conditions (29.2 degrees C) appeared to be sufficiently
stressful to induce a host acclimatization response. All these
observations indicate that temperature and pCO(2) are both forcing
variables affecting T. maxima's physiology and jeopardize its survival
under environmental conditions predicted for the end of this century.},

Title = {Symbiont Chloroplasts Remain Active During Bleaching-Like Response
Induced by Thermal Stress in <i>Collozoum pelagicum</i> (Collodaria,
Retaria)},
Journal = {FRONTIERS IN MARINE SCIENCE},
Year = {2018},
Volume = {5},
Month = {OCT 29},
Abstract = {Collodaria (Retaria) are important contributors to planktonic
communities and biogeochemical processes (e.g., the biologic pump) in
oligotrophic oceans. Similarly to corals, Collodaria live in symbiosis
with dinoflagellate algae, a relationship that is thought to explain
partly their ecological success. In the context of global change, the
robustness of the symbiotic interaction, and potential subsequent
bleaching events are of primary interest for oceanic ecosystems
functioning. In the present study, we compared the ultrastructure,
morphology, symbiont density, photosynthetic capacities and respiration
rates of colonial Collodaria exposed to a range of temperatures
corresponding to natural conditions (21 degrees C), moderate (25 degrees
C), and high (28 degrees C) thermal stress. We showed that symbiont
density immediately decreased when temperature rose to 25 degrees C,
while the overall Collodaria holobiont metabolic activity increased.
When temperature reached 28 degrees C, the holobiont respiration nearly
stopped and the host morphological structure was largely damaged, as if
the host tolerance threshold has been crossed. Over the course of the
experiment, the photosynthetic capacities of remaining algal symbionts
were stable, chloroplasts being the last degraded organelles in the
microalgae. These results contribute to a better characterization and
understanding of temperature-induced bleaching processes in planktonic
photosymbioses.},

Title = {Magnesium and strontium compositions of recent symbiont-bearing benthic
foraminifera},
Journal = {MARINE MICROPALEONTOLOGY},
Year = {2005},
Volume = {58},
Number = {1},
Pages = {31-44},
Month = {DEC 20},
Abstract = {Minor and trace elements in foraminiferal carbonates are potential
paleo-proxies of climate, nutrient and seawater composition. There are
very few reports of trace element composition of symbiont-bearing,
larger foraminifera that are known to be important constituents of
shallow-marine, modem and ancient carbonates. In this paper we examine
the range of variation in Mg and Sr content of Recent species of these
foraminifera from a lagoon of Lakshadweep Atoll (Indian Ocean) and
Akajima Islands, Japan. Two hyaline species, Amphistegina lessonii and
Neorotalia calcar,and two porcellaneous species, Antphisorus hentprichii
and Marginopora vertebralis were collected live from Lakshadweep
islands. Mg/Ca in these foraminifera is of an order of magnitude higher
than the values reported for planktonic and symbiont-free benthic
foraminifera. The Sr/Ca values are, however, comparable with the
reported values in other foraminiferal taxa and they are found to vary
within a narrow range. Electron-probe micro-analysis of three
symbiont-bearing benthic species indicates spatial heterogeneity of high
orders in Mg/Ca composition in all the species. The annual variation in
temperature and pH of the lagoon water cannot explain the observed
amplitude of the compositional variation. The photosynthesis and
respiration of the symbionts and host foraminifera are possibly the
major cause of compositional heterogeneity in individual tests, as has
also been recently postulated for symbiont-bearing planktonic
foraminiferal species. It highlights the need to isolate biological
factors and necessitates species-specific paleotemperature scale in
paleoclimatic analysis. We also analyzed delta O-18, delta C-13, Ca, Mg
and Sr in carefully dissected chambers of a reef-dwelling, porcellaneous
benthic foraminifer, Marginopora kudakajimaensis, collected live in four
seasons. A moderate positive correlation is observed between Mg/Ca and
temperature. However, large inter- and intra-test variation in Mg limits
the precision of Mg/Ca as palaeotemperature proxy. The Sr/Ca of the test
calcite is unrelated to temperature of the sea water. The delta C-13 of
M. kudakajiniaensis does not correlate with delta O-18, Mg/Ca or Sr/Ca.

Journal = {CORAL REEFS},
Year = {2020},
Volume = {39},

Pages = {419-431},

Abstract = {Elevated temperatures and nutrients are degrading coral reef ecosystems,
but the understanding of how early life stages of reef corals respond to
these stressors remains limited. Here, we test the impact of temperature
(mean similar to 27 degrees C vs. similar to 29 degrees C) and nitrate
and phosphate enrichment (ambient, + 5 mu M nitrate, + 1 mu M phosphate
and combined + 5 mu M nitrate with 1 mu M phosphate) on coral larvae
using three Hawaiian coral species with different modes of symbiont
transmission and reproduction: Lobactis scutaria (horizontal, gonochoric
broadcast spawner), Pocillopora acuta (vertical, hermaphroditic brooder)
and Montipora capitata (vertical, hermaphroditic broadcast spawner).
Temperature and nutrient effects were species specific and appear
antagonistic for L. scutaria and M. capitata, but not for P. acuta.
Larvae survivorship in all species was lowest under nitrate enrichment
at 27 degrees C. M. capitata and L. scutaria survivorship increased at
29 degrees C. However, positive effects of warming on survivorship were
lost under high nitrate, but phosphate attenuated nitrate effects when
N/P ratios were balanced. P. acuta larvae exhibited high survivorship (>
91\%) in all treatments and showed little change in larval size, but
lower respiration rates at 29 degrees C. Elevated nutrients (+N+P) led
to the greatest loss in larvae size for aposymbiotic L. scutaria, while
positive growth in symbiotic M. capitata larvae was reduced under
warming and highest in +N+P treatments. Overall, we report a greater
sensitivity of broadcast spawners to warming and nutrient changes
compared to a brooding coral species. These results suggest variability
in biological responses to warming and nutrient enrichment is influenced
by life-history traits, including the presence of symbionts (vertical
transmission), in addition to nutrient type and nutrient stoichiometry.},

Abstract = {Perturbed colonies of Phenganax parrini and Sarcothelia sp. exhibit
migration of symbionts of Symbiodinium spp. into the stolons.
Densitometry and visual inspection indicated that polyps bleached while
stolons did not. When migration was triggered by temperature, light and
confinement, colonies of Sarcothelia sp. decreased rates of oxygen
formation in the light (due to the effects of perturbation on
photosynthesis and respiration) and increased rates of oxygen uptake in
the dark (due to the effects of perturbation on respiration alone).
Colonies of P. parrini, by contrast, showed no significant changes in
either aspect of oxygen metabolism. When migration was triggered by
light and confinement, colonies of Sarcothelia sp. showed decreased
rates of oxygen formation in the light and increased rates of oxygen
uptake in the dark, while colonies of P. parrini maintained the former
and increased the latter. During symbiont migration into their stolons,
colonies of both species showed dramatic increases in reactive oxygen
species (ROS), as visualized with a fluorescent probe, with stolons of
Sarcothelia sp. exhibiting a nearly immediate increase of ROS.
Differences in symbiont type may explain the greater sensitivity of
colonies of Sarcothelia sp. Using fluorescent probes, direct
measurements of migrating symbionts in the stolons of Sarcothelia sp.
showed higher levels of reactive nitrogen species and lower levels of
ROS than the surrounding host tissue. As measured by native
fluorescence, levels of NAD(P) H in the stolons were unaffected by
perturbation. Symbiont migration thus correlates with dramatic
physiological changes and may serve as a marker for coral condition.},

Cassiopea xamachana symbiotic with zooxanthellae: effect of jellyfish
size and season},
Journal = {MARINE ECOLOGY PROGRESS SERIES},
Year = {1998},
Volume = {168},
Pages = {147-162},
Abstract = {The association between the symbiont Symbiodinium microadriaticum
(zooxanthellae) and its host jellyfish, Cassiopea xamachana, was
investigated as a function of jellyfish size and season. Symbiont cell
diameter and volume were higher during January than September. Although
zooxanthella-specific chlorophyll was independent of jellyfish size,
both chlorophyll a and c were higher during January. Regardless of
season, algal density and jellyfish size were inversely related. The
diel mitotic index (MI) of zooxanthellae was phased, with a peak of
0.25\% occurring between 09:00 and 12:00 h. September photosynthetic
rates were always higher than January rates and reflected the seasonal
light and temperature regimes at the latitude of the Florida Keys (USA).
Photosynthesis, when normalized to either zooxanthella density or
protein, displayed an inverse relationship with jellyfish size. Medusan
respiration rates also showed an inverse relationship with jellyfish
size, with September metabolism being higher than that of January. The
carbon budgets calculated for these medusae indicate that the carbon
photosynthetically fixed by the zooxanthellae, and subsequently
translocated to the host, is capable of satisfying about 169\% of the
host's metabolic demand (CZAR) and is independent of both jellyfish size
and season. These seasonally influenced physiological effects underscore
the necessity for seasonal examinations of algal-cnidarian symbioses in
order to understand the photophysiology of the association on an annual
basis.},

Title = {Mitochondrial terminal alternative oxidase and its enhancement by
thermal stress in the coral symbiont <i>Symbiodinium</i>},
Journal = {CORAL REEFS},
Year = {2014},
Volume = {33},
Number = {2},
Pages = {543-552},
Month = {JUN},
Abstract = {A terminal electron acceptor alternative to mitochondrial cytochrome c
oxidase (COX), mitochondrial alternative oxidase (AOX), is ubiquitous in
higher plants and represented in nearly every algal taxon but is poorly
documented in dinoflagellates. AOX competes for electrons with the
conventional COX and has been hypothesized to function as a means of
reducing oxidative stress in mitochondria, as well as a potential
mechanism for ameliorating thermal and other physiological stressors.
Here, the presence of an active AOX in cultured Symbiodinium was assayed
by the response of oxygen consumption to the AOX inhibitor
salicylhydroxamic acid (SHAM) and the COX inhibitor cyanide (CN).
CN-insensitive, SHAM-sensitive oxygen consumption was found to account
for a large portion (26 \%) of Symbiodinium dark respiration and is
consistent with high levels of AOX activity. This experimental evidence
of the existence of a previously unreported terminal oxidase was further
corroborated by analysis of publicly available Symbiodinium
transcriptome data. The potential for enhanced AOX expression to play a
compensatory role in mediating thermal stress was supported by inhibitor
assays of cultured Symbiodinium at low (18 A degrees C), moderate (26 A
degrees C), and high (32 A degrees C) temperature conditions. Maximum
capacity of the putative AOX pathway as a proportion of total dark
oxygen consumption was found to increase from 26 \% at 26 A degrees C to
45 \% and 53 \% at 18 A degrees C and 32 A degrees C, respectively, when
cells were acclimated to the treatment temperatures. Cells assayed at 18
and 32 A degrees C without acclimation exhibited either the same or
lower AOX capacity as controls, suggesting that the AOX protein is
upregulated under temperature stress. The physiological implications for
the presence of AOX in the coral/algal symbiosis and its potential role
in response to many forms of biotic and abiotic stress, particularly
oxidative stress, are discussed.},

Abstract = {The Mg/Ca composition of calcium carbonate tests (shells) secreted by
planktonic foraminifera is increasingly being employed to estimate past
seawater temperatures and reconstruct paleocean and climate records
spanning hundreds of thousands of years. We show, using two
high-resolution microanalysis techniques, that the final chamber of the
planktonic foraminifera Orbulina universa typically comprises between
three and six paired, low and high Mg, growth bands. The number and
spacing of these bands is consistent with a diurnal origin, modulated by
changing pH within the foraminiferal microenvironment due to the
day-night, photosynthesis-respiration cycle of algal symbionts. The
amplitude of Mg/Ca variation within individual tests and across many
daily growth bands cannot be accounted for by seawater temperature in
the shallow, euphotic zone habitat of O. universa. Our results indicate
the Mg/Ca composition of calcite precipitated by O. universa in nature
is strongly influenced by diurnal changes in the biological activity of
algal symbionts and the host foraminifer. This brings into question the
fundamental premise often made in applying Mg/Ca palaeoseawater
thermometry, that the Mg/Ca composition of foraminiferal calcite is
determined by seawater temperature, and whether the Mg/Ca composition of
other planktonic species that are more widely used for palaeoseawater
thermometry are subject to similar influences. (C) 2004 Elsevier B.V.

Abstract = {Most plant species form mycorrhizas, yet these are neglected by plant
physiologists. One consequence of this neglect is reduced ability to
predict plant respiration, because respiration rate (R) in mycorrhizal
roots might be higher than in non-mycorrhizal roots owing to increased
substrate availability associated with enhanced nutrient uptake, coupled
with increased respiratory product demand. Other predictions include
that mycorrhizal colonization will affect scaling of R with tissue
nitrogen concentrations; that mycorrhizal and non-mycorrhizal root R
differ in their response to nutrient supply; and that the impact of
colonization on R is related to fungal biomass. Failure to examine
properly the role of colonization in determining root R means that
current interpretations of root and soil respiration data might be
flawed.},

Abstract = {The sea anemone Anthopleura elegantissima hosts two phylogenetically
different symbiotic microalgae, a dinoflagellate Symbiodinium
(zooxanthellae, ZX) and a chlorophyte (zoochlorellae, ZC). The
photosynthetic productivity (P), respiration (R), and contribution of
algal carbon translocated to the host (CZAR) in response to a year's
seasonal ambient changes of natural light and temperature are documented
for both ZX- and ZC-bearing anemones. Light and temperature both affect
photosynthesis, respiration, and CZAR, as well as various algal
parameters; while there are evident seasonal differences, for the most
part the relative effects on P, R, and CZAR by the two environmental
variables cannot be determined. Net photosynthesis (P-n) of both ZX and
ZC was significantly higher during spring and summer. During these
seasons, the P-n of ZX was always greater than that of ZC. Regardless of
algal symbiont, anemone respiration (R) was significantly higher during
the spring and summer. The annual net carbon fixation rate of anemones
with ZX and ZC was 325 and 276 mg C anemone(-1) year(-1), respectively,
which translates to annual net community productivity rates of 92 and 60
g C m(-1) year(-1) for anemones with ZX or ZC, respectively. CZAR did
not show a clear relationship with season; however the CZAR for ZX was
always significantly greater than for ZC. Lower ZX growth rates, coupled
with higher photosynthetic rates and higher CZAR estimates, compared to
ZC, suggest that if A. elegantissima is simply carbon limited,
ZX-bearing anemones should be the dominant symbiont in the field.
However ZC-bearing anemones persist in low light and reduced temperature
microhabitats, therefore more than the translocation of carbon from ZC
must be involved. Given that global climate change will increase water
temperatures, the potential for latitudinal range shifts of both ZC and
ZX (S. californium and muscatinei) might be used as biological
indicators of thermal shifts in the littoral zone of the Pacific
Northwest.},

Abstract = {This study experimentally investigated the effect of an early summer
short-term summer thermal anomaly in November on Heron Reef (Great
Barrier Reef), on the performance of the coral-algal symbiosis during a
subsequent, thermally induced bleaching event (defined by loss of
symbionts) in February 2009. Fragments of the reef flat coral, Acropora
millepora, exposed to the two heating events lost 78\% of their
symbionts and showed a 64\% decline in dark adapted quantum yield
(Fv/Fm) to values less than 0.25. Whereas corals that were only heated
in the second event lost 57\% symbionts and displayed a 75\% decline in
Fv/Fm to values less than 0.2. Coral in both pre-stressed and non
pre-stressed treatments at 34 degrees C had net photosynthetic rates
significantly less than zero (P-net max<0), suggesting that daytime O-2
respiration rates were significantly greater than rates of O-2 evolution
through photosynthesis. Increases in the daily light field and/or
increases in temperature led to the observation of dark-adapted
xanthophyll de-epoxidation suggesting that the potential for
non-photochemical quenching is maintained into the dark (after 1 h dark
adaption). Pre-stressed corals were also found to have de-epoxidation
ratios three times greater than non pre-stressed corals at 34 degrees C
and xanthophyll pool to Chl a, much greater than non pre-stressed
corals. Combined, these results indicate that symbionts in pre-stressed
corals have a greater ability to dump incoming light energy as heat We
conclude that whilst differences were observed between pre-stressed and
non pre-stressed populations in measurements of photosynthetic
productivity, photosynthetic pigments and areal protein, thermal
bleaching as defined by symbiont loss did not vary between treatments.

Abstract = {Understanding how rising seawater pCO(2) and temperatures impact coral
aragonite accretion is essential for predicting the future of reef
ecosystems. Here, we report 2 long-term (10-11 month) studies assessing
the effects of temperature (25 and 28 degrees C) and both high and low
seawater pCO(2) (180-750 mu atm) on the calcification, photosynthesis
and respiration of individual massive Porites spp. genotypes.
Calcification rates were highly variable between genotypes, but high
seawater pCO(2) reduced calcification significantly in 4 of 7 genotypes
cultured at 25 degrees C but in only 1 of 4 genotypes cultured at 28
degrees C. Increasing seawater temperature enhanced calcification in
almost all corals, but the magnitude of this effect was seawater pCO(2)
dependent. The 3 degrees C temperature increase enhanced calcification
rate on average by 3\% at 180 mu atm, by 35\% at 260 mu atm and by >
300\% at 750 mu atm. The rate increase at high seawater pCO(2) exceeds
that observed in inorganic aragonites. Responses of gross/net
photosynthesis and respiration to temperature and seawater pCO(2) varied
between genotypes, but rates of all these processes were reduced at the
higher seawater temperature. Increases in seawater temperature, below
the thermal stress threshold, may mitigate against ocean acidification
in this coral genus, but this moderation is not mediated by an increase
in net photosynthesis. The response of coral calcification to
temperature cannot be explained by symbiont productivity or by
thermodynamic and kinetic influences on aragonite formation.},

Title = {Organic and inorganic carbon production by algal symbiont-bearing
foraminifera on northwest Pacific coral-reef flats},

Abstract = {Algal symbiont-bearing benthic foraminifera are producers of both
organic and inorganic carbon in coral-reef ecosystems. However, their
contribution to the total budget of reef carbon production has not been
adequately quantified. We used O-2-respirometry and alkalinity-anomaly
techniques to estimate the organic and inorganic carbon production rates
of three species of symbiont-bearing large foraminifera common to coral
reef flats in the northwest Pacific Ocean. The species studied were
Baculogypsina sphaerulata and Calearina gaudichaudii, which both harbor
diatom endosymbionts, and Marginopora kudakajimensis, which harbors
dinoflagellate endosymbionts. Live mature individuals were placed onto
mesh in clear airtight containers filled with filtered seawater. The
containers were incubated for several hours at a constant temperature
and subjected to different levels of light intensity. Seawater was
continuously mixed throughout the experiment. Dissolved oxygen, pH and
total alkalinity were measured before and after incubation. Three
species of larger benthic foraminifera were net organic and inorganic
carbon producers. The P/R ratio exceeded 1 for all species. No
photoinhibition was observed up to 1500 mu mol photons m(-2) s(-1), and
calcification was enhanced by light. These findings suggest that the
three species are net carbon producers adapted to high-light, reef-flat
environments. In addition, we calculated that Baculogypsina sphaerulata
and C. gaudichaudii together accounted for 2-7.5\% of the gross primary
production of a reef-crest community, whereas M. kudakajimensis supplied
1-11\% of the gross primary production of a backreef community. The two
calcarinids and M. kudakajimensis contributed similar to 1 and 10\% of
the inorganic carbon production of seaward reef flat and protected
lagoon communities, respectively. Together with previous reports, these
estimates suggest that algal symbiont-bearing foraminifera play a minor
but essential role in the organic and inorganic carbon production of
coral-reef ecosystems.},

Abstract = {Reindeer lichens (such as Cladonia rangiferina) are important winter
forage for caribou and reindeer and are widely distributed in northern
ecosystems. Widespread lichen communities may be explained by dispersal
from thallus fragments or by fungal ascospores interacting with algal
cells. Since three early stages of interactions between symbionts of the
lichen C. rangiferina have already been established, this study
investigated the effect of three temperatures (5, 20, and 35 A degrees
C) and pH levels (4.5, 6.5, and 8.5) on the early interaction of C.
rangiferina by quantifying morphological differences for three fungal
(internode length, number of lateral branches, number of appressoria)
and one algal (cell diameter) characters using Scanning Electron
Microscopy. The results showed that the fungal characters were
significantly altered by the extreme temperatures (5 and 35 A degrees C)
and the pH level produced differences in the fungal characters at pH
8.5. The alga was more tolerant of the wide temperature range than the
fungus while the fungus was more tolerant of pH changes than the alga.
An interaction effect by temperature and pH on the symbiont characters
was also observed. The study raises questions regarding the range of
conditions tolerated by other species of lichens and their symbionts.},

Abstract = {The impact of elevated CO2 and temperature on photosynthesis and
calcification in the symbiont-bearing benthic foraminifer Marginopora
vertebralis was studied. Individual specimens of M. vertebralis were
collected from Heron Island on the southern Great Barrier Reef
(Australia). They were maintained for 5 weeks at different temperatures
(28, 32 A degrees C) and pCO(2) (400, 1,000 A mu atm) levels spanning a
range of current and future climate-change scenarios. The photosynthetic
capacity of M. vertebralis was measured with O-2 microsensors and a
pulse-amplitude-modulated chlorophyll (Chl) fluorometer, in combination
with estimates of Chl a and Chl c (2) concentrations and calcification
rates. After 5 weeks, control specimens remained unaltered for all
parameters. Chlorophyll a concentrations significantly decreased in the
specimens at 1,000 A mu atm CO2 for both temperatures, while no change
in Chl c (2) concentration was observed. Photoinhibition was observed
under elevated CO2 and temperature, with a 70-80 \% decrease in the
maximum quantum yield of PSII. There was no net O-2 production at
elevated temperatures in both CO2 treatments as compared to the control
temperature, supporting that temperature has more impact on
photosynthesis and O-2 flux than changes in ambient CO2. Photosynthetic
pigment loss and a decrease in photochemical efficiency are thus likely
to occur with increased temperature. The elevated CO2 and high
temperature treatment also lead to a reduction in calcification rate
(from +0.1 to >-0.1 \% day(-1)). Thus, both calcification and
photosynthesis of the major sediment-producing foraminifer M.
vertebralis appears highly vulnerable to elevated temperature and ocean
acidification scenarios predicted in climate-change models.},

caspase-3 activation level in corals, increased significantly in
response to hypoxia stress. Furthermore, it was revealed that activities
such as coral cell division and calcification were inhibited under
hypoxia. These results collectively suggest that acute hypoxia stress

Abstract = {Throughout its geographic range, the temperate-zone anemone Anthopleura
elegantissima is the host of one or both of two distinctively different
symbiotic microalgae: a dinoflagellate Symbiodinium (zooxanthellae, ZX)
and a chlorophyte (zoochlorellae, ZC). Given the broad vertical
intertidal and latitudinal range of this anemone, we investigated the
role of temperature in determining whether A. elegantissima supports one
algal symbiont over the other and whether temperature regulates the
observed distributions of natural populations of ZX and ZC. Temperature
appears to be a key factor in regulating both the photophysiology and
metabolism of this algal-cnidarian association. In anemones containing
ZX, neither algal densities nor chlorophyll content varied with
temperature (6-24.degreesC); in contrast, anemones with ZC displayed
reduced densities and chlorophyll content at the highest temperature
treatment (24 degreesC). Both. ZX and ZC photosynthetic rates were
directly related to temperature, as were anemone respiration rates. The
higher photosynthetic rates, maintenance of a stable algal density and
chlorophyll content, and higher potential contribution of algal carbon
toward animal respiration (CZAR) suggest that the ZX are the more viable
symbiont as temperature increases, but we suggest alternative reasons
why ZC are preserved in this symbiotic association. Elevated
temperatures reduce ZC densities and chlorophyll, suggesting that higher
temperatures affect this relationship in a negative fashion, presumably
due to a higher cost of maintaining ZC by the association;
alternatively, these costs may be affiliated with the deterioration of
the ZC themselves. These results suggest that temperature may be one of
the most significant environmental parameters that sets the intertidal
microhabitat and latitudinal distribution patterns of the two algal taxa
observed in the field.},

Abstract = {Environmental stress, such as an increase in the sea surface
temperature, triggers coral bleaching, a profound dysfunction of the
mutualist symbiosis between the host cnidarians and their photosynthetic
dinoflagellates of the Family Symbiodiniaceae. Because of climate
change, mass coral bleaching events will increase in frequency and
severity in the future, threatening the persistence of this iconic
marine ecosystem at global scale. Strategies adapted to coral reefs
preservation and restoration may stem from the identification of the
succession of events and of the different molecular and cellular
contributors to the bleaching phenomenon. To date, studies aiming to
decipher the cellular cascade leading to temperature-related bleaching,
emphasized the involvement of reactive species originating from
compromised bioenergetic pathways (e.g. cellular respiration and
photosynthesis). These molecules are responsible for damage to various
cellular components causing the dysregulation of cellular homeostasis
and the breakdown of symbiosis. In this review, we synthesize the
current knowledge available in the literature on the cellular mechanisms
caused by thermal stress, which can initiate or participate in the cell
cascade leading to the loss of symbionts, with a particular emphasis on
the role of each partner in the initiating processes.},

Number = {6},
Month = {JUL},
Abstract = {In many cases, understanding species' responses to climate change
requires understanding variation among individuals in response to such
change. For species with strong symbiotic relationships, such as many
coral reef species, genetic variation in symbiont responses to
temperature may affect the response to increased ocean temperatures. To
assess variation among symbiont genotypes, we examined the population
dynamics and physiological responses of genotypes of Breviolum
antillogorgium in response to increased temperature. We found broad
temperature tolerance across genotypes, with all genotypes showing
positive growth at 26, 30, and 32 degrees C. Genotypes differed in the
magnitude of the response of growth rate and carrying capacity to
increasing temperature, suggesting that natural selection could favor
different genotypes at different temperatures. However, the historical
temperature at which genotypes were reared (26 or 30 degrees C) was not
a good predictor of contemporary temperature response. We found
increased photosynthetic rates and decreased respiration rates with
increasing contemporary temperature, and differences in physiology among
genotypes, but found no significant differences in the response of these
traits to temperature among genotypes. In species with such broad
thermal tolerance, selection experiments on symbionts outside of the
host may not yield results sufficient for evolutionary rescue from
climate change.},
