Significance Reef corals in the Persian/Arabian Gulf (PAG) withstand exceptionally high salinity and regular summer temperatures of ∼35 °C that kill conspecifics elsewhere. These thermotolerant communities established themselves within only ∼6,000 y under pressure rapid climate change can therefore inform how other coral reefs may respond to global warming. One key thermotolerance PAG is their symbiosis with Symbiodinium thermophilum . Phylogeographic evidence indicates this symbiont...
Summary In order to understand physiological, ecological and biological processes, it is often crucial determine an organism's volume surface area ( SA ). Most of the available methods require sacrificing organism or at least removing from its natural habitat, in measure these parameters. Advances computer vision algorithms now allow us parameters using non‐destructive, three‐dimensional modelling. The addition cloud computing availability freeware make this tool widely accessible....
Abstract Light quality is a crucial physical factor driving coral distribution along depth gradients. Currently, 30 m limit, based on SCUBA regulations, separates shallow and deep mesophotic ecosystems ( MCE s). This definition, however, fails to explicitly accommodate environmental variation. Here, we posit novel definition for regional or reef‐to‐reef outlook of s the light vs. community–structure relationship. A combination ecological methods enabled us clarify ambiguity in relation...
Coral reefs are the epitome of species diversity, yet number described scleractinian coral species, framework-builders reefs, remains moderate by comparison. DNA sequencing studies rapidly challenging this notion exposing a wealth undescribed but evolutionary and ecological significance diversity largely unclear. Here, we present an annotated genome for one most ubiquitous corals in Indo-Pacific (Pachyseris speciosa) uncover, through comprehensive genomic phenotypic assessment, that it...
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 Unfortunately, most these data remain unpublished which limits our understanding regional and global reproductive patterns.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 CSD includes 6178 observations (3085 were unpublished) time or day for over 300 species 61 genera from 101...
Abstract Coral reefs are highly diverse ecosystems that thrive in nutrient-poor waters, a phenomenon frequently referred to as the Darwin paradox 1 . The energy demand of coral animal hosts can often be fully met by excess production carbon-rich photosynthates their algal symbionts 2,3 However, understanding mechanisms enable corals acquire vital nutrients nitrogen and phosphorus from is incomplete 4–9 Here we show, through series long-term experiments, uptake dissolved inorganic alone...
The phenomenon of coral fluorescence in mesophotic reefs, although well described for shallow waters, remains largely unstudied. We found that representatives many scleractinian species are brightly fluorescent at depths 50–60 m the Interuniversity Institute Marine Sciences (IUI) reef Eilat, Israel. Some these have distribution maxima (40–100 m). Several individuals from displayed yellow or orange-red fluorescence, latter being essentially absent corals shallowest parts this reef....
Abstract Aim Coral reefs shift between distinct communities with depth throughout the world. Yet, despite over half a century of research on coral reef gradients, researchers have not addressed driving force these patterns. We present theoretical, process‐based model light’s influence shallow to mesophotic transition as single quantitative framework. also share an interactive web application. Moving beyond ecological proxy will enhance conducted deeper reefs. Location Global; subtropical and...
<title>Abstract</title> Ocean warming is increasing the incidence, scale, and severity of global-scale coral bleaching mortality, culminating in third global event that occurred during record marine heatwaves 2014-2017. While local effects these events have been widely reported, implications remain unknown. Analysis 15,066 reef surveys 2014-2017 revealed 80% surveyed reefs experienced significant 35% mortality. The extent mortality was assessed by extrapolating results from using...
Abstract Robotic advances and developments in sensors acquisition systems facilitate the collection of survey data remote challenging scenarios. Semantic segmentation, which attempts to provide per‐pixel semantic labels, is an essential task when processing such data. Recent deep learning approaches have boosted this task's performance. Unfortunately, these methods need large amounts labeled data, usually a challenge many domains. In environmental monitoring instances, as coral reef example...
Abstract Large-scale imaging techniques are used increasingly for ecological surveys. However, manual analysis can be prohibitively expensive, creating a bottleneck between collected images and desired data-products. This is particularly severe benthic surveys, where millions of obtained each year. Recent automated annotation methods may provide solution, but reflectance do not always contain sufficient information adequate classification accuracy. In this work, the FluorIS, low-cost...
Abstract Due to increasing frequency of disturbances shallow reefs, it has been suggested that Mesophotic Coral Ecosystems (MCEs, 30–150 m depth) may serve as a refuge for corals and source larvae can facilitate the recovery degraded reefs. As such, they have received increased attention in past decade, yet remained understudied regarding recruitment dynamics. Here we describe coral dynamics on settlement tiles their adjacent natural habitats (10 vs. 50 depths) Eilat, over period 5.5 years....
Population size structure provides information on demographic characteristics, such as growth and decline, enabling post-hoc assessment of spatial differences in susceptibility to disturbance. Nevertheless, very few studies have quantified data scleractinian corals along a shallow-mesophotic gradient, partly because previously inaccessible depths. Here, we report the coral size-frequency distributions at morphology level (six forms) species for ten representative locally broad depth gradient...
Major floods pose a severe threat to coastal receiving environments, negatively impacting environmental health and ecosystem services through direct smothering with sediment nutrient loading. This study examined the short long-term impacts of February 2022 major flood event on mud extent nitrogen flux in Moreton Bay (the Bay), large, sub-tropical embayment Southeast Queensland, Australia. Short-term were assessed three days after peak by sampling surface water at 47 sites direction...
In an endeavor to study natural systems at multiple spatial and taxonomic resolutions, there is urgent need for automated, high-throughput frameworks that can handle plethora of information. The coalescence remote-sensing, computer-vision, deep-learning elicits a new era in ecological research. However, complex systems, such as marine-benthic habitats, key processes still remain enigmatic due the lack cross-scale automated approaches (mms kms) community structure analysis. We address this...
Coral reefs are biodiversity hotspots, where new species continue to be discovered. Stylophora pistillata, a depth-generalist coral, is widely distributed throughout the Indo-Pacific and has long been considered poster child for phenotypic plasticity. It occupies wide range of reef habitats exhibits myriad gross morphologies. Here, we used reduced representation genome sequencing (nextRAD) assess genetic structure adults recruits S. pistillata across shallow mesophotic populations in...
Abstract Fluorescence is highly prevalent in reef-building corals, nevertheless its biological role still under ongoing debate. This feature of corals was previously suggested to primarily screen harmful radiation or facilitate coral photosynthesis. In mesophotic ecosystems (MCEs; 30-150 m depth) experience a limited, blue-shifted light environment. Consequently, contrast their shallow conspecifics, they might not be able rely on photosynthates from photosymbionts as main energy source....
Abstract Background Mesophotic coral communities are increasingly gaining attention for the unique biological diversity they host, exemplified by numerous mesophotic fish species that continue to be discovered. In contrast, many of photosynthetic scleractinian corals observed at depths assumed depth-generalists, with very few characterised as mesophotic-specialists. This presumed lack a specialised community remains largely untested, phylogenetic studies on have rarely included samples and...
