Turtles and Tortoises Are in Trouble [PDF]
Current Biology, 2020 Turtles and tortoises (chelonians) have been integral components of global ecosystems for about 220 million years and have played important roles in human culture for at least 400,000 years. The chelonian shell is a remarkable evolutionary adaptation, facilitating success in terrestrial, freshwater and marine ecosystems.

The Anatomical Record, EarlyView.Abstract The organization and function of reptilian excurrent ducts remain poorly characterized, particularly in Neotropical snakes. We provide the first integrative morphological, histochemical, immunohistochemical, and ultrastructural analysis of the proximal post‐testicular ducts of Crotalus durissus across reproductive stages.

Carrion ecology: concepts, interdisciplinary synthesis, and perspectives
Biological Reviews, EarlyView.ABSTRACT Carrion is a ubiquitous resource in both terrestrial and aquatic ecosystems, yet it has long been overlooked in ecological research. Over the past two decades, studies on carrion and the many organisms that exploit it have flourished, revealing not only wide‐ranging ecological functions but also significance far beyond ecology.

Land birds on atolls: diversity, origin, and function
Biological Reviews, EarlyView.ABSTRACT Oceanic islands are global hotspots of avian biodiversity and endemism. Their isolation and distinct environmental conditions have uniquely shaped the evolutionary trajectories of island birds, while, in turn, land bird communities have become critical providers of ecological functions to island ecosystems.

Effects of oiling common raven nests on ravens and greater sage‐grouse in sagebrush ecosystems
The Journal of Wildlife Management, EarlyView.We oiled and sham‐oiled raven nests across 7 sites in the Great Basin to measure the effects of egg‐oiling on co‐occurring populations of ravens and sage‐grouse. Oiling raven eggs ended embryonic development of oiled eggs, reduced raven densities, resulted in more than a doubling of nest‐survival probabilities of sage‐grouse nests, and spurred ...

Effects of off‐highway vehicle activity on Arizona wildlife: a systematic literature review
The Journal of Wildlife Management, EarlyView.The published literature indicates that off‐highway vehicles (OHVs) predominantly negatively affect native Arizona amphibians, mammals, and reptiles, while effects of OHVs on native Arizona birds are mostly unknown or neutral. Abstract Off‐highway vehicle (OHV) recreation has dramatically increased in Arizona, USA, prompting concerns about potential ...
