Abstract Despite being one of the simplest metazoans, corals harbor some most highly diverse and abundant microbial communities. Differentiating core, symbiotic bacteria from this host-associated consortium is essential for characterizing functional contributions but has not been possible yet. Here we characterize coral core microbiome demonstrate clear phylogenetic divisions between micro-scale, niche habitats within host. In doing so, discover seven distinct bacterial phylotypes that are...
Bleaching of the Great Barrier Reef The Australian (GBR) is one Earth's most extraordinary natural wonders, but it vulnerable to climate change. Ainsworth et al. have tracked effects three decades increasing heat stress on coral organisms. In past, pulses elevated temperatures that presaged hot seasons stimulated acclimation organisms and resilience thermal stress. More recently, temperature hikes been severe precluded acclimation. result has bleaching death; notably extreme during 2016 in...
Abstract Globally, collapse of ecosystems—potentially irreversible change to ecosystem structure, composition and function—imperils biodiversity, human health well‐being. We examine the current state recent trajectories 19 ecosystems, spanning 58° latitude across 7.7 M km 2 , from Australia's coral reefs terrestrial Antarctica. Pressures global climate regional impacts, occurring as chronic ‘presses’ and/or acute ‘pulses’, drive collapse. Ecosystem responses 5–17 pressures were categorised...
Abstract Temperate reefs from around the world are becoming tropicalised, as warm‐water species shift their distribution towards poles in response to warming. This is already causing profound shifts dominant foundation and associated ecological communities canopy seaweeds such kelp replaced by tropical species. Here, we argue that cascading consequences of tropicalisation for ecosystem properties functions warming temperate depend largely on taxa end up dominating seafloor. We put forward...
Success and impact metrics in science are based on a system that perpetuates sexist racist “rewards” by prioritizing citations factors. These flawed biased against already marginalized groups fail to accurately capture the breadth of individuals’ meaningful scientific impacts. We advocate shifting this outdated value advance through principles justice, equity, diversity, inclusion. outline pathways for paradigm shift values multidimensional mentorship promoting mentee well-being. actions...
The success of any symbiosis under stress conditions is dependent upon the responses both partners to that stress. coral particularly susceptible small increases temperature above long term summer maxima, which leads phenomenon known as bleaching, where intracellular dinoflagellate symbionts are expelled. Here we for first time used quantitative PCR simultaneously examine gene expression response orthologs Acropora aspera and their symbiont Symbiodinium. During an experimental bleaching...
ABSTRACT For ecosystems vulnerable to environmental change, understanding the spatiotemporal stability of functionally crucial symbioses is fundamental determining mechanisms by which these may persist. The coral Pachyseris speciosa a successful generalist that succeeds in diverse reef habitats. nature this suggests it have capacity form significant microbial partnerships facilitate access range nutritional sources within different Here, we propose metaorganism hosting three distinct...
We propose that the coral holobiont should be conceptualized as a diverse transient microbial community is responsive to surrounding environment and encompasses simple, redundant, resident microbiome small conserved core microbiome. Most importantly, we show comparable microbiomes of other organisms studied thus far. Accurately characterizing coral-microbe interactions provides an important baseline from which functional roles niches within microbes reside can deciphered.
Worldwide, increasing coastal development has played a major role in shaping coral reef species assemblages, but the mechanisms underpinning distribution patterns remain poorly understood. Recent research demonstrated delayed larval fishes exposed to suspended sediment, highlighting need further understand interaction between sediment as stressor and energetically costly activities such growth that are essential support biological fitness. We examined gill morphology microbiome clownfish...
A changing climate is driving increasingly common and prolonged marine heatwaves (MHWs) these extreme events have now been widely documented to severely impact ecosystems globally. However MHWs rarely recently considered when examining temperature-induced degradation of coral reef ecosystems. Here we consider extreme, localised thermal anomalies, nested within broader increases in sea surface temperature, which fulfil the definitive criteria for MHWs. These acute intense events, referred...
Previous studies of coral viruses have employed either microscopy or metagenomics, but few attempted to comprehensively link the presence a virus-like particle (VLP) genomic sequence. We conducted transmission electron imaging and virome analysis in tandem characterize most conspicuous viral types found within dominant Pacific reef-building genus Acropora. Collections for this study inadvertently captured what we interpret as natural outbreak infection driven by aerial exposure reef flat...
