🦤🦈🌊 Angelshark (Squatina squatina) detections on baited remote underwater video stations in Cardigan Bay demonstrate repeated habitat use, supporting the IUCN Cardigan-Caernarfon Bay Important Shark and Ray Area as important habitat area. bit.ly/esr01518
🦈 🌐 🧪 🦤 46 years of basking shark sightings in Ireland reveal rising numbers, larger groups, and seasonal hotspots tied to ocean conditions. Ireland remains a key habitat for this species, underscoring the need for targeted and dynamic management. bit.ly/esr01515
🐢🌐🦤🧪What do immature green turtles eat in São Tomé? We combined stable isotopes and RNA/DNA to uncover diet shifts and nutritional condition across habitats, key insights for conservation in the Gulf of Guinea. bit.ly/esr01513
🌐🧪🦤 Endangered Cook Inlet belugas were absent from the Kenai River during peak fishing season, despite high salmon counts. Acoustic and visual monitoring suggests anthropogenic activity may be influencing their use of key foraging habitat. bit.ly/esr01509
🌐🧪🦤 Endangered Japanese eel has declined across East Asia; downstream contraction in distribution and loss of effective habitat in the Yangtze River since the 1960s highlights the urgent need for fishing bans, habitat restoration, and long-term monitoring. bit.ly/esr01504
🌐🧪🦤 We estimated numbers of loggerhead and green turtles for 19 years in Florida Bay and estimated survival of loggerheads. Green turtle numbers increased and loggerheads showed no trend. Loggerhead survival was generally high in this protected habitat. bit.ly/esr01502
🌐🧪🦤 New research on the endangered St. Lawrence Estuary (SLE) beluga characterizes blubber and prey lipid profiles across its food web. Sex-specific beluga profiles and taxonomic and seasonal prey shifts were identified, establishing a biochemical baseline for conservation research. bit.ly/esr01501
🦤🧪🌐🦭 Ringed seals are exposed to more ship traffic as #SeaIce declines. In Arctic Alaska, #RingedSeals were regularly exposed to multiple types of vessels during 2013-2022 open‑water seasons. The effects of vessel exposure require more research. bit.ly/esr01500
🦤🧪🌐🦈 Shark vertebrae hold lifelong chemical records. Using stable isotopes, our new study reconstructs diet and habitat shifts in the Critically Endangered scalloped bonnethead—delivering key ecological insights to better guide conservation. bit.ly/esr01498
🦤🧪🌐🦈 Ultrasound scans identify the Al Wajh Lagoon (Red Sea) as the first documented gestation site for Critically Endangered halavi #guitarfish and Endangered reticulate #whipray, refining size-at-maturity and indicating localized pupping. bit.ly/esr01497
🌐🧪🦤 The 1st DNA-verified record of copper shark Carcharhinus brachyurus in Chile; 24 sharks were reorted in artisanal landings at Antofagasta, extending species' eastern Pacific range southward and highlighting need for monitoring and management of bycatch. bit.ly/esr0146
🌐🧪🦤 North Pacific male loggerheads utilize high-latitude foraging grounds around 40°N during the summer regardless of their growth stage or reproductive status. High-latitude habitats would be more important for males than previously thought. bit.ly/esr01495
🌐🧪🦤 24 males contributed to the nests of 23 females at Jumby Bay, Antigua. Our data show low multiple paternity and an even breeding sex ratio for 2013, providing baselines for hawksbills in the Eastern Caribbean to establish trends over time. bit.ly/esr01491
🐳🌐🦤🧪 New data from tagged fin whales in southern New England show low non-song call rates during mid-summer. Calls from males were most frequent during nighttime feeding, indicating context-dependent sound production and implications for acoustic detection. bit.ly/esr01487
🦤🧪🌐🦈 Long-term tagging of the flapnose houndshark Scylliogaleus quecketti conducted by the Oceanographic Research Institute in the Pondoland MPA found this species extremely resident with a small home range. It is likely well protected in no-take MPAs. bit.ly/esr01488
🦤🧪🌐 Pinna nobilis is an endemic Mediterranean bivalve, critically endangered after a mass mortality event that began in 2016. In Tabarca Marine Reserve, Spain, mortality reached 100%. Pinna rudis is now filling its ecological niches. bit.ly/esr01483
🦤🧪🌐 🐟 A decade of acoustic telemetry reveals new insight into survival of juvenile #GulfSturgeon (Acipenser desotoi) in Florida’s #ApalachicolaRiver, improving understanding of this threatened species and supports informed conservation efforts. bit.ly/esr01484
🐢🦤🌐🧪 Tracking of 23 #LoggerheadTurtles from Tanegashima revealed five core foraging areas across warm and cold seasons in the East China Sea. Larger individuals tended to use the Tsushima Strait. Results inform targeted conservation planning. bit.ly/esr01478
🐢🌐🧪🦤 Community-engaged surveys of Green sea turtle in the Azores Archipelago found 69 sightings near Faial Island and Pico Island. All were juveniles (10–79 cm), confirming the area as a transient foraging ground. bit.ly/esr01482
🦤 🌐 🧪 🐢 Green turtles need on average 1.5 years to recover from anthropogenic injuries, longer for severe trauma. Recurring propeller strikes and fishing line entanglements at Liuqiu Island, Taiwan, highlight the need for go-slow zones and responsible fishing. bit.ly/esr01472
🦤🌐🧪🐊 New research identifies key preferences for low banks & flat ground in captive Chinese alligtors. Optimizing these habitat features can improve breeding success for this critically endangered species. #WildlifeConservation #Alligator #EndangeredSpecies bit.ly/esr01476
