Deep coral reefs (that is, mesophotic ecosystems) can act as refuges against major disturbances affecting shallow reefs. It has been proposed that, through the provision of propagules, such deep may aid in reef recovery; however, this "reseeding" hypothesis remains largely untested. We conducted a genome-wide assessment two scleractinian species with contrasting reproductive modes, to assess potential for connectivity between (40 m) and (12 depths on an isolated system Western Atlantic...
The CARICOMP monitoring network gathered standardized data from 52 seagrass sampling stations at 22 sites (mostly Thalassia testudinum-dominated beds in reef systems) across the Wider Caribbean twice a year over period 1993 to 2007 (and some cases up 2012). Wide variations community total biomass (285 >2000 g dry m−2) and annual foliar productivity of dominant T. testudinum (<200 were found among sites. Solar-cycle related intra-annual leaf detected latitudes > 16°N. Hurricanes had little no...
The recruitment of juvenile corals and post-settlement mortality are important processes for coral population dynamics reef community ecology. I monitored survival on a severely disturbed in Bermuda from 1981 to 1989 adjacent healthy reefs 1986 1990. Porites astreoides was the dominant recruiting species at all sites, due release brooded planulae that may settle rapidly. Bermuda's reef, Diploria spp., were poor recruiters, perhaps broadcast mode reproduction these species. However, spp. have...
Strontium to calcium ratios (Sr/Ca) are reported for a massive brain coral Diploria labyrinthiformis collected from the south shore of Bermuda and strongly correlated with both sea surface temperature (SST) mean annual skeletal growth rate. High Sr/Ca correspond cold SSTs slow rate vice versa. We provide quantitative calibration extension SST along axis maximum derive growth‐dependent Sr/Ca–SST equation reconstruct western subtropical North Atlantic past 223 years. When influence is excluded...
Shallow coral reef ecosystems worldwide are affected by local and global anthropogenic stressors. Exploring fish assemblages on deeper reefs is therefore important to examine their connectivity, help understand the biodiversity, ecology, distinctiveness, evolutionary history threats in this sparsely studied environment. Conducting visual surveys Bermuda slope a nearby seamount at depths from 15‒300 m, we document decreasing biomass diversity with increasing depth. Fish were primarily...
Five taxa of talitrid amphipods were found in the archipelago Bermuda, which three recorded there for first time. Four these are supralittoral wrack generalists: Platorchestia monodi BOLD:AAB3402, (a unique Molecular Operational Taxonomic Unit according to Barcode Index Number system), a related species recognized by molecular methods, platensis BOLD:AAA2949, Mexorchestia carpenteri BOLD:AAC1491 and Tethorchestia antillensis; one terrestrial leaf-litter generalist: Talitroides alluaudi. A...
Worldwide coral reefs face catastrophic damage due to a series of anthropogenic stressors. Investigating how ecosystems are connected, in particular across depth, will help us understand if deeper harbour distinct communities. Here, we explore changes benthic community structure 15–300 m depths using technical divers and submersibles around Bermuda. We report high levels floral faunal differentiation with assemblages occupying each depth surveyed, except 200–300 m, corresponding the lower...
Invasive lionfish (Pterois volitans and P. miles) are now ubiquitous throughout the Caribbean Western Atlantic on shallow deep reefs. Recent surveys in Bermuda have revealed dense aggregations of mesophotic reefs (60 m depth), yet these densities not pervasive across at this depth. Using diver-led visual reef sites, study examines how variations potential ecological drivers may affect distribution. Significant correlations were found with prey fish density biomass, where sites higher...
<title>Abstract</title> The Gulf Stream forms part of the upper-ocean limb Atlantic Meridional Overturning Circulation (AMOC), playing an essential role in redistributing heat northward and greatly influencing regional climates North Atlantic. Understanding path strength variability on longer timescales is vital to contextualise its present-day weakening fully appreciate sensitivity forcing. We present a 558-year long (1456–2013) proxy record sea surface temperature from Bermudan stalagmite...
Coastal ecosystems and the livelihoods they support are threatened by stressors acting at global local scales. Here we used data produced Caribbean Marine Productivity program (CARICOMP), longest, largest monitoring in wider Caribbean, to evidence local-scale (decreases water quality) global-scale (increases temperature) across basin. Trend analyses showed that visibility decreased 42% of stations, indicating chronic widespread. On other hand, only 18% stations increases temperature would be...
Societal Impact Statement We rely on plants and fungi for most aspects of our lives. Yet are under threat, we risk losing species before know their identity, roles, potential uses. Knowing names, distributions, threats first steps toward effective conservation action. Accessible products like field guides online resources engage society, harnessing collective support conservation. Here, review current knowledge the UK Overseas Territories, highlighting gaps to help direct future research...
On low-lying, tropical and sub-tropical coastlines freshwater marshes may be replaced by salt‑tolerant mangroves in response to relative sea-level rise. Pollen analysis of radiocarbon‑dated sediment cores showed that such a change occurred Hungry Bay, Bermuda during the late Holocene. This well-established paleoenvironmental trajectory provides an opportunity explore if geochemical proxies (bulk-sediment δ13C Rock-Eval pyrolysis) can reconstruct known environmental changes sea level. We...
We used a secondary ion mass spectrometry (SIMS) microprobe to analyze magnesium‐to‐calcium (Mg/Ca) and strontium‐to‐calcium (Sr/Ca) ratios of high‐Mg calcite loculi within the skeleton shallow water gorgonian, Plexaurella dichotoma , from Bermuda. A cross section gorgonian reveals embedded proteinaceous gorgonin arranged in concentric rings about axial core. Viewed section, are fan‐shaped, 10–140 μm diameter, composed bundles needle‐shaped crystals that appear radiate out calcification...
