New methods are needed for genomic-scale analysis of emerging model organisms that exemplify important biological questions but lack fully sequenced genomes. For example, there is an urgent need to understand the potential corals adapt climate change, few molecular resources available studying these processes in reef-building corals. To facilitate genomics studies and other non-model systems, we describe transcriptome sequencing using 454, as well strategies assembling a useful catalog genes...
The impacts of warming seas on the frequency and severity bleaching events are well documented, but potential for different Symbiodinium types to enhance physiological tolerance reef corals is not understood. Here we compare functionality properties juvenile when experimentally infected with one two homologous exposed combined heat light stress. A suite indicators including chlorophyll a fluorescence, oxygen production respiration, as pigment concentration consistently demonstrated lower...
Corals and reef fish choose nice homes Young animals tend to disperse into new habitats. Can we use populations in protected areas colonize nearby recovering or overused habitats? It seems that for corals fish, the answer may be no. Dixson et al. show dispersing juvenile were overwhelmingly attracted healthy reefs but repelled by seaweeds degraded (see Perspective Bruno). Thus, even species appear passive their choice of habitat have stronger preferences than thought. Science , this issue p....
Abstract Understanding the potential for coral adaptation to warming seas is complicated by interactions between symbiotic partners that define stress responses and difficulties of tracking selection in natural populations. To overcome these challenges, we characterized contribution both animal host algae thermal tolerance corals have already experienced considerable on par with end‐of‐century projections most reefs. Thermal Platygyra daedalea from hot Persian Gulf where summer temperatures...
The induction of larval attachment and metamorphosis benthic marine invertebrates is widely considered to rely on habitat specific cues. While microbial biofilms hard substrates have received considerable attention as signals for a wide phylogenetically diverse array invertebrates, the presumed chemical settlement produced by bacteria date not been characterized. Here we isolated fully characterized first signal from that induced acroporid coral larvae (Acropora millepora). metamorphic cue...
Juveniles of a number corals with horizontal transmission dinoflagellate endosymbionts naturally acquire and maintain Symbiodinium types that differ from those found in adult populations. However, the duration this early period symbiont flexibility successional changes leading to dominance by characteristic (homologous) type are unknown. To document natural succession within juvenile corals, we monitored communities juveniles Acropora tenuis millepora for 3.5 years. originating one three...
Selective breeding increases the resilience of reef-building corals to climate warming.
Abstract The discovery of multi-species synchronous spawning scleractinian corals on the Great Barrier Reef in 1980s stimulated an extraordinary effort to document times other parts globe. Unfortunately, most these data remain unpublished which limits our understanding regional and global reproductive patterns. Coral Spawning Database (CSD) collates much disparate into a single place. CSD includes 6178 observations (3085 were unpublished) time or day for over 300 species 61 genera from 101...

The majority of reef-building corals acquire their obligate algal symbionts (Symbiodinium) from the environment. However, factors shaping initial establishment coral-algal symbioses, including parental effects, local environmental conditions and availability symbionts, are not well understood. This study monitored uptake maintenance Symbiodinium in juveniles two common corals, Acropora tenuis millepora, that were reciprocally explanted between sites where adult colonies host different types...
Understanding the sedimentation and turbidity thresholds for corals is critical in assessing potential impacts of dredging projects tropical marine systems. In this study, we exposed two species coral sampled from offshore locations to six levels total suspended solids (TSS) 16 weeks laboratory, including a 4 week recovery period. Dose-response relationships were developed quantify lethal sub-lethal corals. The sediment treatments affected horizontal foliaceous (Montipora aequituberculata)...
Here we describe an efficient and effective technique for rearing sexually-derived coral propagules from spawning through larval settlement symbiont uptake with minimal impact on natural populations. We sought to maximize survival while minimizing expense daily husbandry maintenance by experimentally determining optimized conditions protocols gamete fertilization, cultivation, induction of crustose coralline algae, inoculation newly settled juveniles their dinoflagellate Symbiodinium. Larval...
The future of coral reefs under increasing CO 2 depends on their capacity to recover from disturbances. To predict the recovery potential communities that are fully acclimatized elevated , we compared relative success recruitment and later life stages at two volcanic seeps adjacent control sites in Papua New Guinea. Our field experiments showed effects ocean acidification (OA) rates were up an order magnitude greater than survival growth established corals. Settlement rates, recruit juvenile...
Abstract Scleractinian corals occur in tropical regions near their upper thermal limits and are severely threatened by rising ocean temperatures. However, several recent studies have shown coral populations can harbour genetic variation tolerance. Here, we extended these approaches to study heat tolerance of the Persian/Arabian Gulf, where heat‐tolerant local experience extreme summer temperatures (up 36°C). To evaluate whether selection has depleted tolerance, estimate potential future...
Coral reefs and their associated marine communities are increasingly threatened by anthropogenic climate change. A key step in the management of threats is an efficient accurate end-to-end system coral monitoring that can be generally applied to shallow water reefs. Here, we used RGB drone-based imagery a deep learning algorithm develop classifying bleached unbleached corals. Imagery was collected five times across one year, between November 2018 2019, assess bleaching potential recovery...
Symbioses between microbes and higher organisms underpin high diversity in many ecosystems, including coral reefs, however mechanisms underlying the early establishment of symbioses remain unclear. Here we examine roles Symbiodinium type cell surface recognition algal endosymbiosis reef-building coral, Acropora tenuis. We found 20–70% infection success (proportion larvae infected) five-fold abundance exposed to ITS-1 C1 compared D first 96 h following exposure. The highest within occurred...
The effects of temperature and light on the breakdown coral-Symbiodinium symbiosis are well documented but current understanding their roles during initial uptake establishment is limited. In this study, we investigate how affect algal symbionts, ITS1 types C1 D, by juveniles broadcast-spawning corals Acropora tenuis A. millepora. Elevated temperatures had a strong negative effect Symbiodinium in both coral species, with at 31 °C showing as little 8% compared to 87% 28 °C. Juveniles high...
Despite a wealth of information on sexual reproduction in scleractinian corals, there are regional gaps reproductive records. In the Gulf Oman Arabian Sea, timing was assessed four common species broadcast spawning corals using field surveys gamete maturity and aquarium observations activity. The appearance mature gametes within same month for Acropora downingi, A. hemprichii, Cyphastrea microphthalma Platygyra daedalea (≥ 75% colonies, n = 848) indicated synchronous multi-specific season....
Abstract The Arabian Peninsula borders the hottest reefs in world, and corals living these extreme environments can provide insight into effects of warming on coral health disease. Here, we examined reef at 17 sites across three regions along northeastern (Persian Gulf, Strait Hormuz Oman Sea) representing a gradient environmental conditions. Persian Gulf has seasonal fluctuations temperature chronic hypersalinity, whereas other two experience more moderate Field surveys identified 13...
Reef-building corals show a marked decrease in total species richness from the tropics to high latitude regions. Several hypotheses have been proposed account for this pattern context of abiotic and biotic factors, including temperature thresholds, light limitation, aragonite saturation, nutrient or sediment loads, larval dispersal constraints, competition with macro-algae other invertebrates, availability suitable settlement cues micro-algal symbionts. Surprisingly, there is paucity data...
Novel restoration methods are currently under consideration worldwide to help coral reefs recover or become more resilient higher temperature stress. Critical field-based information concerning the paradigm of “local is best” lacking for many methods; which essential determine risk and feasibility associated with restoration. One method involves breeding corals from different reef regions expected variation in heat tolerance moving those offspring new locations enhance survival; thereby...
