Abiotic variables drive different aspects of fish community trait variation and species richness across the continental United States

Journal of Animal Ecology, EarlyView.
Trait distributions provide insight into how niches overlap within a broader trait space. By integrating individual‐level trait observations from different communities, we can explore how facets of trait dimensionality vary across environmental conditions.

Resource Availability and Habitat Quality Drive Time‐Lag Effects in High‐Altitude Ungulate Distribution

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

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.

Reflecting on livestock-related interventions in the 2020-2023 drought in Ethiopia and identifying areas for improvement: A qualitative study of expert opinions

Journal of Agriculture and Rural Development in the Tropics and Subtropics
Between 2020 and 2023 Ethiopia faced its worst drought for four decades, losing over four million livestock and placing over twelve million people into food insecurity. The overall aim of this study was to gain detailed, real reflections on the livestock-

Potential vs. Realized Large Carnivore Density: The Influence of Livestock on Carnivore Carrying Capacity Estimation

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 ...

Basal body temperature as a biomarker of reproductive state in ewes: A multi‐method comparison

Australian Veterinary Journal, EarlyView.
This study quantified body temperature dynamics throughout reproductive stages in crossbred ewes based on complementary monitoring techniques. Five ewes from a semi‐extensive farming system were included in two sub‐trials: animals were first assessed in the prepubertal stage and, subsequently, an oestrous cycle was induced by intravaginal progesterone ...

The collective application of shorebird tracking data to conservation

Conservation Biology, EarlyView.
Abstract Addressing urgent conservation issues, such as the drastic declines of North American migratory birds, requires creative, evidence‐based, efficient, and collaborative approaches. The abundance of over 50% of monitored North American shorebird populations has declined by over 50% since 1980. To address these declines, we developed a partnership

Comprehensive framework for assessing and optimizing existing research networks

Conservation Biology, EarlyView.
Abstract Conservation, monitoring, and research networks, or collections of ecological research sites unified under a common mission of data collection or a research mission, are essential infrastructure for understanding large landscapes. However, most networks developed opportunistically over decades rather than through systematic design, creating ...
