Nests in trees are as good as or better than cliffs for two formerly persecuted, primarily cliff nesting eagles in Spain: a cautionary tale in defining the habitat of range‐restricted or threatened species

open access: yesWildlife Biology, EarlyView.
In the late‐20th century, golden and Bonelli's eagles suffered population declines on the Iberian Peninsula, partly due to human persecution. Habitat assessments – especially for Bonelli's eagles – always found or assumed strong associations with cliffs that provided nesting sites.

Human‐Caused Leopard Deaths in Sri Lanka Are Concentrated in Central Highlands' Estate Mosaics: Evidence From 17 Years of Mortality Records 人为因素导致斯里兰卡豹死亡事件集中于中部高地种植园镶嵌景观:来自 17 年死亡记录的证据

open access: yesWildlife Letters, EarlyView.
Human‐caused leopard deaths in Sri Lanka averaged 9.65 ± 4.5 records year−1 over 17 years (2008–2024; n = 164), with records highly clustered in the central highland mosaic ecosystem. Mortality was dominated by adult males and driven primarily by snaring in plantation landscapes, and indicating an increase approximately 0.7–0.8 deaths per year.

Stratified Bed Conditions Impact on Scour Development at Engineering Structures

open access: yes
River flow contraction by engineering structures (intakes, embankment, abutments, spurs, guide banks) to flow leads to flow pattern modification, concentration of streamliners, sharp drop in water level, local increase in velocity, and development of ...

Comparative evaluation of funnel, box, and camera traps for reptile and amphibian inventory

open access: yesWildlife Society Bulletin, EarlyView.
We used data from 5 herpetological inventories conducted in Florida to evaluate the relative efficacy of funnel, box, and motion‐triggered camera traps for detecting reptile and amphibian species along drift‐fence arrays. Our results suggest that a hybrid array design (funnel traps + central camera trap) is best suited for general herpetofaunal ...

Temporal community change in stream ecosystems varies by assemblage across US climates

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Ecosystem properties are temporally dynamic. Temporal variability has been shown to decrease with increasing levels of biological organization (i.e. from population to community and ecosystem levels).

Scour Development at Elliptical Guide Banks during Multiple Floods

open access: yes
The scour development at bridge abutments and elliptical guide banks during multiple floods is studied. At the upstream head of the elliptical guide bank, a streamline concentration, a local increase in velocity, vortex structures, and the development of

Torpor‐assisted migration: Regular use of shallow torpor reduces rest‐phase energy expenditure for songbirds during migration

open access: yesJournal of Animal Ecology, EarlyView.
Migrating songbirds regularly use shallow torpor (up to 98% of birds for some species) to save energy (up to 42%) during inactive periods. This Ruby‐crowned Kinglet Corthylio calendula that was captured after a spring snowstorm highlights the value of being able to save energy when encountering unfavourable conditions.
