Endangered Species Research

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

Critically Endangered tope sharks face threats across Europe. Combining angler, fishery and beam trawl data confirms a vital pupping ground in the Dutch Wadden Sea and nearby North Sea waters, supporting efforts for future protection. bit.ly/esr01473

When an American crocodile in South Florida died unexpectedly during a routine capture event, a field necropsy revealed clinical signs of Pb toxicosis and 22.42 g of Pb in the animal’s stomach. bit.ly/esr01474

ESR Special #27. Southern Africa is home to well over 200 species of #Chondrichthyans. Over a third are considered threatened. This Special is open to all authors, including submissions based on presentations at the 8th SARS in 2025. Contribute now! bit.ly/esr_special27

ESR Special #26. Initiated at the end of the 20th century, many #MarineTurtle monitoring programs have been ongoing for two or more decades and provide valuable insights into population dynamics and conservation. Contribute now! bit.ly/esr_special26

We developed a novel modeling framework, integrating disparate data types over 45 yrs, to estimate true survival of the #MojaveDesertTortoise. Our results suggest positive effects of precipitation and higher survival of adult males. bit.ly/esr01468

Our morphometric study of the endangered Longfin Smelt (Spirinchus thaleichthys) shows clear sex-based shape differences and weak geographic trends. These findings help inform conservation and reproductive biology in the San Francisco Estuary. bit.ly/esr01471

A 3-year study evaluated imagery classification techniques to assess feasibility of modeling individual Peirson’s milk-vetch (Astragalus magdalenae var. peirsonii) within the Imperial Sand Dunes Recreation Area, California. bit.ly/esr01467

#GreenTurtle reproductive dynamics! 🐢 Over half of harvested females off Nicaragua were adults, of which 6–39% bred each year. Size regulations in Nicaragua may disproportionately target large juvenile females, urging policy updates. #TurtleConservation. bit.ly/esr01464

We used satellite imagery to estimate the population of the short-tailed #albatross on the Senkaku Islands, recently classified as an independent species. The population comprised only about 150 pairs, indicating urgent conservation needs. bit.ly/esr01462

#Leatherback #seaturtles perform extensive post-nesting migrations, which can be influenced by mesoscale eddies and ocean currents. We use satellite telemetry to investigate the routes taken by turtles in the #IndianOcean. bit.ly/esr_58_417

Amazon River dolphins are elusive 🐬, but isotopes + satellite tracking reveal variation in their feeding behavior. Using δ15N-AA, this study sets a new baseline for their trophic ecology and highlights them as flexible top predators in the Amazon Basin. bit.ly/esr_58_303

Concern about nesting #FlatbackTurtles on Delambre Island, Western Australia. Despite natural cycles, population currently appears to be dropping. Monitoring and adaptive management are vital to understand and protect this unique population. bit.ly/esr_58_287

Habitat degradation may hinder #pangolin ability to raise pups, despite their perceived adaptability. We documented the elusive wild female Manis javanica during maternal and non-maternal stages, offering insights for evidence-based conservation. bit.ly/esr_58_223

Endangered #LakeChubsucker in Canada are feeling the heat – literally. 🔥🐟 While they hold their own in low-oxygen waters, rising temps are already affecting their behaviour, which is concerning as climate change intensifies. bit.ly/esr_58_275

Wind beneath my wings: we describe the spatial and temporal extent of the post-fledging dependence period of the endangered #ChacoEagle (Buteogallus coronatus), related with individual sex, body condition and ecoregion. bit.ly/esr_58_193

Sulcaria isidiifera is a critically endangered lichen that only occurs on the central coast of California. Translocation may serve as a potential conservation measure to protect this rare lichen. bit.ly/esr_58_103

Automated cameras in remote field sites captured breeding data for at-risk #doublecrestedcormorant in #StraitofGeorgia. Multievent capture-recapture models were used to understand negative effects on nest success across entire breeding season. bit.ly/esr_58_85

Using DNA from skin samples, age (1–45 yr) and sex of Lahille’s bottlenose #dolphins in Brazil were estimated. With <600 left, this non-invasive #epigenetic tool aids survival predictions and #conservation 🧬🐬. bit.ly/esr_58_137
