AnimalsColonizing populations at the leading edge of range expansion are expected to have a reduced genetic diversity and strong genetic structure caused by genetic drift and allele surfing.

Wildlife Biology, EarlyView.The rapid decline of African wildlife populations demands immediate action to mitigate further losses and restore ecosystems. A key factor influencing wildlife distribution is the relationship between the energetic needs of species and the availability of forage, both in terms of quality and quantity.

Integrative Zoology, EarlyView.Our analysis revealed that while climate strongly influenced species distributions, habitat change drove most observed delays in distribution responses. In terms of community ecology, dispersed communities exhibited shorter time lags than concentrated groups. Analyses of lag duration revealed a 5–6‐year distribution lag effect in high‐altitude ungulate

Climate change effects on rangelands and rangeland management: affirming the need for monitoring
Ecosystem Health and Sustainability, 2017 Uncertainty as to the extent and magnitude of changes in conditions that might occur due to climate change poses a problem for land and resource managers as they seek to adapt to changes and mitigate effects of climate variability.

Decades of Enclosure Protection Exert Composite Effects on Grassland Grasshopper Communities
Integrative Zoology, EarlyView.Decades of enclosure protection have altered grasshopper community structure, with species‐specific effects on population dynamics. For the low‐mobility grasshopper Chorthippus fallax, abundance did not differ strongly between exclosure‐protected and overgrazed areas, but its egg development duration was longer in exclosures. The two C.

Smoke signals: Measuring wildlife smoke exposure with animal‐borne and stationary sensors
Methods in Ecology and Evolution, EarlyView.Abstract Wildfires are becoming larger, more frequent and more severe, producing smoke plumes that degrade air quality hundreds of kilometres away and for days to weeks after an active fire. Despite public health and safety concerns regarding wildfire smoke, we know little about how free‐ranging wildlife experience or respond to these exposures.

Animal Conservation, EarlyView.In an unfenced mixed‐use savanna landscape in Namibia, we compared realized densities of leopards and cheetahs estimated using spatial capture–recapture models with prey‐based carrying capacity predictions. Leopard densities exceeded predictions based on wild prey alone but closely matched livestock‐supplemented models, suggesting that vulnerable ...
