Abstract Seagrass conservation is critical for mitigating climate change due to the large stocks of carbon they sequester in seafloor. However, effective and its potential provide nature-based solutions hindered by major uncertainties regarding seagrass extent distribution. Here, we describe characterization world’s largest ecosystem, located The Bahamas. We integrate existing spatial estimates with an updated empirical remote sensing product perform extensive ground-truthing seafloor 2,542...
Abstract Regional endothermy has evolved several times in marine fishes, and two competing hypotheses are generally proposed to explain the evolutionary drivers behind this trait: thermal niche expansion elevated cruising speeds. Evidence support either hypothesis is equivocal, ecological advantages conferred by fishes remain debated. By compiling published biologging data collecting precise speed measurements from free‐swimming wild, we directly test whether endothermic encounter broader...
Trait-based ecology is a rapidly growing approach for developing insights and predictions data-poor species. Caudal tail fin shape has the potential to reveal much about energetics, activity of fishes can be measured from field guides, which particularly helpful data-sparse One outstanding question whether swimming speed in sharks related two morphological traits: caudal aspect ratio (CFAR, height2/tail area) lobe asymmetry (CLAR). We derived both metrics species drawings Sharks world (Ebert...
Catch-and-release fishing is an important component of ecotourism industries and scientific research worldwide, but its total impact on animal physiology, health survival understudied for many species fishes, particularly sharks. We combined biologging blood chemistry to explore how this fisheries interaction influenced the physiology two widely distributed, highly migratory shark species: blue (Prionace glauca) tiger (Galeocerdo cuvier). Nineteen sharks were caught by drum line or...
Abstract Catch-and-release (C&R) angling is often touted as a sustainable form of ecotourism, yet the fine-scale behaviour and physiological responses released fish unknown, especially for hard-to-study large pelagic species like Atlantic bluefin tuna (ABFT; Thunnus thunnus). Multi-channel sensors were deployed recovered from 10 ABFTs in simulated recreational C&R event off west coast Ireland. Data recorded 6 to 25 hours, with one ABFT (tuna X) potentially suffering mortality minutes...
The thermal sensitivity of metabolism is widely studied due to its perceived importance for organismal fitness and resilience future climate change. Almost all such studies estimate at a variety constant temperatures, with very little work exploring how varies during temperature However, in nature rarely static, so our existing understanding from experiments may not reflect influences natural systems. Using closed-chamber respirometry, we estimated the aerobic metabolic rate an aquatic...
We compared the covering behavior of four sea urchin species, Tripneustes gratilla, Pseudoboletia maculata, Toxopneustes pileolus, and Salmacis sphaeroides found in waters Malapascua Island, Cebu Province Bolinao, Panagsinan Province, Philippines. Specifically, we measured amount type material on each urchin, several cases, recovery debris after stripping animal its cover. that gratilla have a higher affinity for plant material, especially seagrass, to maculata which prefer cover themselves...
