Influence of Age and Exposure Pathway on Copper and Cadmium Mixture Toxicity: A Study on Daphnia magna

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Metal contamination in aquatic ecosystems poses substantial risks to freshwater organisms, with mixture effects often deviating from predictions based on single‐metal toxicity. Understanding how age‐specific sensitivities and multiple exposure pathways influence mixture effects is critical for accurate risk assessment.

Unusual Patterns of Lateral Scutes in Two Olive Ridley Turtles and Their Genetic Assignment to the Thai Andaman Sea Populations of Lepidochelys olivacea Eschscholtz, 1829

open access: yesBiology
Two stranded Lepidochelys-like sea turtles were rescued from the Thai Andaman Sea coastline by veterinarians of the Phuket Marine Biological Center (PMBC), one in May of 2019 and another in July of 2021. They were first identified as olive ridley turtles

Resource Availability Modulates Effects of Fluorine Free Firefighting Foams

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Fluorine‐free foam (F3) alternatives that lack per‐ and polyfluoroalkyl substances (PFAS) are rapidly being adopted for firefighting operations and will be entering ecosystems. Despite this, little is known about their impact on freshwater communities.

Importance of woody patches and vegetation heterogeneity in Texas tortoise microhabitat use

open access: yesWildlife Biology, EarlyView.
Microhabitat sites provide important resources and thermal conditions to reptile species that can vary spatially and temporally. This study assessed Texas tortoise Gopherus berlandieri microhabitat use and its relationship with carapace temperature during their active (April–October) and inactive seasons (November–March) between January 2023 and ...

Intraspecific variation in carapace morphology among fiddler crabs (Genus Uca) from the Atlantic coast of Brazil

open access: yesAquatic Biology, 2014
Isolation due to geographical barriers should promote genetic and morphological divergence among populations. Marine currents flowing in opposing directions along landmasses can constitute barriers that isolate populations dependent upon aquatic ...

Movement and Space Use Patterns of the Beale's Eyed Turtle (Sacalia bealei) Suggest Sensitivity to Environmental Changes and Poaching 比氏眼斑龟 (Sacalia bealei) 的活动与空间利用模式揭示其对环境变化及盗猎的敏感性

open access: yesWildlife Letters, EarlyView.
Using radiotelemetry, we found that the movement and home range of the endangered Sacalia bealei varied significantly across reproductive classes and seasons, with males exhibiting greater movement than females during wet and mating seasons. The species exhibits strong aquatic dependence, favoring deep pools interspaced among riffle‐pool sequences ...

From landscapes to lesions: Pathology's role in wildlife mortality investigations and conservation health

open access: yesWildlife Society Bulletin, EarlyView.
Wildlife mortality investigations are important toward understanding health threats to wildlife and management considerations. The who, what, why and how are critical pieces of these investigations. Wildlife pathologists play a central role in this process in elucidating causes and contributors to mortality. Abstract To effectively recognize and manage

Hox Gene Variation Drives Morphological Specialization of Humpback Grouper Cromileptes altivelis

open access: yesIntegrative Zoology, EarlyView.
Cromileptes altivelis exhibits a distinctive “sunken head and humpback” morphology, formed through cranial remodeling. Genetic analyses identified unique amino acid variants in Hoxa7a and Hoxa10b, with functional tests confirming their role in enhancing osteoblast activity and driving cranial remodeling.
