Trace Element Contamination in Top Predatory Elasmobranchs From the Southern Black Sea: Implications for Ecosystem Health and Risk Assessment

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Environmental pollution resulting from the rapid increase in human population, urbanization, intensive use of chemicals in agriculture, and industrial development has reached a level that threatens natural life today. Trace elements are one of the most important factors causing significant levels of pollution in the environment and are added ...

Water depth and human disturbance drive occupancy of endangered softshell turtles (Nilssonia spp.) in eastern Nepal

open access: yesWildlife Biology, EarlyView.
Freshwater turtles play vital roles in maintaining the health of aquatic ecosystems by supporting ecological balance, nutrient cycling and regulating prey populations. Unfortunately, they are among the most threatened species worldwide. Habitat fragmentation, illegal trade, overharvesting for meat, and use in ethnomedicinal practices have severely ...

Human‐Caused Leopard Deaths in Sri Lanka Are Concentrated in Central Highlands' Estate Mosaics: Evidence From 17 Years of Mortality Records 人为因素导致斯里兰卡豹死亡事件集中于中部高地种植园镶嵌景观:来自 17 年死亡记录的证据

open access: yesWildlife Letters, EarlyView.
Human‐caused leopard deaths in Sri Lanka averaged 9.65 ± 4.5 records year−1 over 17 years (2008–2024; n = 164), with records highly clustered in the central highland mosaic ecosystem. Mortality was dominated by adult males and driven primarily by snaring in plantation landscapes, and indicating an increase approximately 0.7–0.8 deaths per year.

Bycatch Dynamics from a Small-Scale Shrimp Trap Fishery in the Mediterranean Sea

open access: yesDiversity, 2022
Small-scale fisheries (SSFs) in the Mediterranean and Black seas play a significant social and economic role, representing 84% of the fishing fleet (70,000 vessels), 26% of total revenue (USD 633 million) and 60% of total employment (150,000 people ...

Comparative evaluation of funnel, box, and camera traps for reptile and amphibian inventory

open access: yesWildlife Society Bulletin, EarlyView.
We used data from 5 herpetological inventories conducted in Florida to evaluate the relative efficacy of funnel, box, and motion‐triggered camera traps for detecting reptile and amphibian species along drift‐fence arrays. Our results suggest that a hybrid array design (funnel traps + central camera trap) is best suited for general herpetofaunal ...

Bycatch of marine mammals and seabirds: Occurrence and mitigation

open access: yes, 2021
Gillnet fisheries are generally considered environment-friendly, causing limited bottom-impact and generating high-quality fish. Nevertheless, gillnets are also associated with high risks of bycatch of non-target animals, including seabirds and marine mammals. To fulfil Denmark’s obligations with regards to European legislations and other international

Sensory Biology of the Franciscana (Pontoporia blainvillei, Pontoporiidae, Cetartiodactyla): Ontogenetic Modifications of Vibrissae and Vibrissal Crypts

open access: yesIntegrative Zoology, EarlyView.
The transition of cetaceans from a terrestrial to an aquatic environment involved a crucial sensory adaptation to environments with limited visibility. Vibrissae, important mechanoreceptors, undergo an ontogenetic transformation in odontocetes. This research describes the histomorphology of vibrissae and crypts at different developmental stages ...

Mitigating bycatch and depredation of marine mammals in longline fisheries

open access: yesICES Journal of Marine Science, 2015
AbstractDemersal and pelagic longline fisheries involve frequent and geographically widespread interactions with many individuals, populations, and species of marine mammals. Animals sometimes suffer mortality and serious injury following these interactions, attracted mainly to longlines as a source of food.

Fishing Activity Affected Odontocete Cetacean Distribution in a Marine Protected Area in the East China Sea

open access: yesIntegrative Zoology, EarlyView.
Spatiotemporal distribution of odontocete cetaceans within China's Jiushan Archipelago National Nature Reserve was investigated. Fishing vessels significantly reduced both cetacean acoustic detections and feeding activity, whereas gillnets selectively suppressed cetacean feeding behavior without affecting overall cetacean detection rates.

Review of bycatch mitigation measures in tuna longline fishery

open access: yesNIPPON SUISAN GAKKAISHI, 2010
This review classiˆes and explains the bycatch mitigation measures in tuna longline ˆshery based on theirfunctional mechanism across bycatch species. In longline ˆshery bycatch mortality occurs through a commonprocess that typically follows these stages: 1) ˆshing operations overlap with the distribution of non-targetanimals; 2) non-target animals ...
