The evidence base for ranger patrol effectiveness in conservation and how to improve it

Biological Reviews, EarlyView.
ABSTRACT Ranger patrols are a cornerstone of wildlife protection efforts around the world and occur across all ecological governance systems. Evidence that patrols reduce threats to wildlife and enable their recovery has not been systematically examined previously.

Utterance evolution: the road to generative, combinatorial communicators

Biological Reviews, EarlyView.
ABSTRACT Language has long been considered uniquely complex in the animal kingdom; however, animal research over the last decade has begun to challenge some long‐standing premises about exactly which language capacities are uniquely human. The task of resolving why and how complex communication systems evolve, particularly human language, has ...

Dental development in the tropical gar (Atractosteus tropicus) and the evolution of vertebrate dentitions

Developmental Dynamics, EarlyView.
Abstract Background Dentitions have diversified enormously during vertebrate evolution, involving reductions, modifications, or allocations to prey seizing and processing regions. A combination of ancient and novel features related to dental and oropharyngeal apparatuses is found in extant lineages of non‐teleost fishes, such as the gars.

Long‐Distance, Transfrontier Carnivore Dispersals in Southern Africa

Ecology and Evolution
Information on long‐range dispersal in tropical carnivores is limited compared to their temperate counterparts. Here we present data on long‐range, transboundary dispersals for three species of tropical carnivores: African wild dog (Lycaon pictus ...

Legacy effects of redlining on the distribution of greenspaces in US cities

Frontiers in Ecology and the Environment, EarlyView.
We investigated how a discriminatory housing policy—redlining—has shaped the spatial patterns and configurations of greenspaces throughout 177 cities in the contiguous US. Housing segregation has been a long‐term development practice that has sequestered communities of color to areas with elevated environmental and public health risks.

Effect of age class on the survivorship and spatial movement patterns of headstarted Texas horned lizards soft‐released into an urban population

The Journal of Wildlife Management, EarlyView.
When compared to resident lizards of the corresponding age class, juvenile headstarted Texas horned lizards soft‐released into an urban population exhibited more favorable responses to short‐term translocation objectives (i.e., daily movement rates, home range sizes, and survival rates) than did conspecifics headstarted to the adult age class ...

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 ...

Exploring the limits of saving a subspecies: The ethics and social dynamics of restoring northern white rhinos (Ceratotherium simum cottoni)

Conservation Science and Practice, 2020
The northern white rhino (Ceratotherium simum cottoni) is functionally extinct with only two females left alive. However, cryopreserved material from a number of individuals represents the potential to produce additional individuals using advanced ...
