Environmental Toxicology and Chemistry, Volume 43, Issue 11, Page 2365-2376, November 2024.Abstract Parabens are alkyl esters of p‐hydroxybenzoic acid that are commonly used as preservatives in personal care products such as cosmetics. Recent studies have revealed the presence of parabens in surface and tap water because of their use as disinfection products; however, little is known about their occurrence in biological samples and their ...

Vulnerability to lead toxicosis and bioindicator utility of deer scavengers in New York
The Journal of Wildlife Management, Volume 88, Issue 8, November 2024.Wildlife may be exposed to lead through ingestion of contaminated big game harvested with lead bullets. We identified avian and mammalian scavengers of white‐tailed deer in New York and conducted species vulnerability and utility assessments. Our analyses point to bald eagles as the most vulnerable to lead toxicosis and best‐suited bioindicator for ...

The Journal of Wildlife Management, Volume 88, Issue 8, November 2024.We examined the impacts of recreational intensity on a dominant prey species, facultative avian and mammalian scavengers, and ground‐nesting birds within a sagebrush‐steppe ecosystem. Recreation had a positive relationship with facultative scavenger abundance and a negative relationship with ground‐nesting birds.

A three-decade review of telemetry studies on vultures and condors [PDF]
, 2018 Telemetry-based movement research has become central for learning about the behavior, ecology and conservation of wide-ranging species. Particularly, early telemetry studies were conducted on vultures and condors due to three main reasons: i) these birds

Journal of Forensic Sciences, Volume 69, Issue 6, Page 1985-1995, November 2024.Abstract Vertebrate scavengers represent important taphonomic agents that can act on a body, particularly when in an outdoor environment. Understanding the effects of these agents will direct how and where to search for human remains and influence the likelihood of discovery in a particular region.

Ibis, Volume 166, Issue 4, Page 1368-1383, October 2024.Understanding how diverse assemblages of scavengers can coexist on shared ecological resources is a fundamental challenge in community ecology. However, current approaches typically focus on behaviour at carcass provisioning sites, missing how important differences in movement behaviour and foraging strategies can facilitate sympatric species ...

Flapping rates of migrating and foraging Turkey Vultures <i>Cathartes aura</i> in Costa Rica
Vulture News, 2006 Local and migrating populations of Turkey Vultures Cathartes aura co-exist in Costa Rica in autumn and spring (Stiles & Skutch 1989). We studied the flapping rates of individuals from these two populations to compare flight modes and the amount of energy invested in active flight. Migrants tended to fly higher in more stable air than local birds, which
