Mutualisms between reef-building corals and endosymbiotic dinoflagellates are particularly sensitive to environmental stress, yet the ecosystems they construct have endured major oscillations in global climate. During winter of 2008, an extreme cold-water event occurred Gulf California that bleached genus Pocillopora harbouring a thermally ‘sensitive’ symbiont, designated Symbiodinium C1b-c , while colonies possessing D1 were mostly unaffected. Certain recovered quickly others suffered...
Climate change is negatively affecting the stability of natural ecosystems, especially coral reefs. The dissociation symbiosis between reef-building corals and their algal symbiont, or bleaching, has been linked to increased sea surface temperatures. Coral bleaching significant impacts on corals, including an increase in disease outbreaks that can permanently entire reef ecosystem. Yet, little known about immune system. In this study, whole transcriptome analysis holobiont each associate...
Stony corals in the genus Pocillopora are among most common and widely distributed of Indo-Pacific and, as such, often subject physiological ecological research. In far Tropical Eastern Pacific (TEP), they major constituents shallow coral communities, exhibiting considerable variability colony shape branch morphology marked differences response to thermal stress. Numerous intermediates occur between morphospecies that may relate extensive hybridization. The diversity TEP was analysed...
Abstract Aim Using high‐resolution genetic markers on samples gathered from across their wide distributional range, we endeavoured to delimit species diversity in reef‐building Pocillopora corals. They are common, ecologically important, and widespread throughout the Indo‐Pacific, but phenotypic plasticity response environmental conditions nearly featureless microskeletal structures confound taxonomic assignments limit an understanding of ecology evolution. Location Red Sea, Arabian/Persian...
Scleractinian corals of the genus Pocillopora (Lamarck, 1816) are notoriously difficult to identify morphologically with considerable debate on degree which phenotypic plasticity, introgressive hybridization and incomplete lineage sorting obscure well-defined taxonomic lineages. Here, we used RAD-seq resolve phylogenetic relationships among seven species represented by 15 coral holobiont metagenomic libraries. We found strong concordance between datasets, reads that mapped damicornis...
Global climate change has increased the number and severity of stressors affecting species, yet not all species respond equally to these stressors. Organisms may employ cellular mechanisms such as apoptosis autophagy in responding stressful events. These two pathways are often mutually exclusive, dictating whether a cell adapts or dies. In order examine differences response stress, we compared immune four coral with range disease susceptibility. Using RNA-seq novel pathway analysis, were...
The flexibility to associate with more than one symbiont may considerably expand a host's niche breadth. Coral animals and dinoflagellate micro-algae represent of the most functionally integrated widespread mutualisms between two eukaryotic partners. Symbiont identity greatly affects coral's ability cope extremes in temperature light. Over its broad distribution across Eastern Pacific, ecologically dominant branching coral, Pocillopora grandis , depends on dinoflagellates Durusdinium glynnii...
Abstract Genetic data are rapidly advancing our understanding of various biological systems including the ecology and evolution coral–algal symbioses. The fine‐scale interactions between individual genotypes host symbiont remain largely unstudied constitute a major gap in knowledge. By applying microsatellite markers developed for both symbiont, we investigated intracolony diversity, prevalence stability Symbiodinium glynni (type D1 ) multilocus association with dense populations Pocillopora...
Abstract As coral reefs continue to decline worldwide, it becomes ever more necessary understand the connectivity between populations develop efficient management strategies facilitating survival and adaptation of in future. Orbicella faveolata is one most important reef‐building corals Caribbean has recently experienced severe population reductions. Here, we utilize a panel nine microsatellite loci evaluate genetic structure O. infer across ten sites spanning wider region. Populations are...
Diseases affect coral species fitness and contribute significantly to the deterioration of reefs. The increase in frequency severity disease outbreaks has made evaluating determining resistance a priority. Phylogenetic patterns immunity can provide important insight how corals may respond current future environmental and/or biologically induced diseases. purpose this study was determine if immunity, number diseases prevalence show phylogenetic signal among Caribbean corals. We characterized...
Immunity is an important biological trait that influences the survival of individuals and fitness a species. Immune defenses are costly likely compete for energy with other life-history traits, such as reproduction growth, affecting overall Competition among these traits in scleractinian corals could influence dynamics structural integrity coral reef communities. Due to variability within populations across species, it colonies population/species adjust their immune system available...
Abstract Jumonji (JmjC) domain proteins are known regulators of gene expression and chromatin organization by way histone demethylation. Chromatin modification remodeling provides a means to modulate the activity large numbers genes, but importance this class predicted histone-modifying enzymes for different aspects post-developmental processes remains poorly understood. Here we test function all 11 non-lethal members in regulation circadian rhythms sleep. We find loss every Drosophila JmjC...
The CARD-CC/Bcl10/MALT1-like paracaspase (CBM) signaling complexes composed of a CARD-coiled-coil (CC) family member (CARD9, -10, -11 or -14), Bcl10 and the type 1 MALT1 play pivotal role in immunity, inflammation cancer. Targeting proteolytic activity is potential therapeutic interest. However, little known about evolutionary origin original functions CBM complex. Type paracaspases originated before last common ancestor planulozoa (bilaterians cnidarians). Notably bilaterians, Ecdysozoa...
Abstract Caribbean reef‐building corals in the genus Acropora have been declining dramatically since 1980s and are now listed as threatened. The study of their complex reproductive system (mixed asexual sexual) population structure requires highly polymorphic nuclear genetic markers. Of eight previously developed microsatellite loci for A. palmata , only five behaved a Mendelian fashion four reliably amplified sister species, cervicornis. Here, nine novel markers presented that increase...
Long-lasting transcriptional changes underlie a number of adaptations that contribute to alcohol use disorders (AUD). Chromatin remodeling, including histone methylation, can confer distinct, long-lasting changes, and methylases are known play role in the development addiction. Conversely, little is about relevance Jumonji (JmjC) domain-containing demethylases AUDs. We systematically surveyed alcohol-induced phenotypes null mutations all 13 Drosophila JmjC genes.We used collection mutants,...
Malpelo, a small rocky offshore island that supports one of the few coral populations in eastern Pacific, was visited on June 1-5, 1999 with purpose evaluating status communities. Using rapid visual methods, cover major categories sessile organisms and health condition species were assessed at 8 stations between 11 31 m depth. “El Arrecife”, which is largest formation seems to have suffered 20% reduction live since 1972 when mean value 65% recorded. This decline, probably originated by...
The scleractinian genus Meandrina is unique to the western Atlantic. Species diversity has varied from 12 two currently recognized taxa, Caribbean meandrites (Linnaeus, 1758) and brasiliensis (Milne-Edwards Haime, 1848), endemic Brazil. A second species, danae been considered a synonym of M. or an ecomorph meandrites. Field observations, examination specimens, literature review indicated presence third, morphologically different species. multi-variable approach, with morphometric,...
