A proof of concept for linking individual identity to camera traps

open access: yesWildlife Biology, EarlyView.
Small mammal movements are difficult to monitor, both visually and with remote tracking devices, due to the animals' small body size and elusive behavior. Cameras deployed at fixed locations can provide continuous, non‐invasive records in natural habitats, yet camera‐derived indices remain sparsely validated and generally do not allow inference at the ...

Intraspecific variability rivals interspecific differences in root traits of temperate tree seedlings

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Global change and associated disturbances are increasing the risk of regeneration failure for tree species in temperate forests. Seedlings are particularly vulnerable to water stress due to their shallow root systems, making below‐ground plasticity a potentially key ...

Views from the Inside: Reflections on the Modern Hospital

open access: yesThe Political Quarterly, EarlyView.
Abstract There's a constant refrain in the press, on social media and from populist politicians that the NHS is dying on its feet. How accurate is this picture? This article takes a behind‐the‐scenes look at daily life in a modern, big city hospital. The Queen Elizabeth is now the biggest workplace in Birmingham.

Edges as ecological filters: Asymmetrical orientation‐specific arthropod activity across forest boundaries

open access: yesInsect Science, EarlyView.
Moderate retention forestry creates structurally sharp forest edges that act as ecological filters, shaping orientation‐specific activity of ground‐dwelling arthropods. Using drift‐fence pitfall traps, we show that activity aligned with ecotones is more frequent than activity across forest–clearcut boundaries, particularly among detritivores.

Climatic conditions, landscape, and habitat quality drive patch occupancy and larval density of a threatened mire butterfly

open access: yesInsect Science, EarlyView.
The Moorland Clouded Yellow (Colias palaeno) benefited from cattle grazing in three different ways by (i) fostering the nectar supply; (ii) enhancing rejuvenation of the host plant (Vaccinium uliginosum); and (iii) improving microclimatic conditions for successful development of the immature stages.

Can Wapiti (Cervus elaphus) Browsing Stimulate the Chemical Defense of Taxus cuspidata—A Case of Northeast China Tiger and Leopard National Park

open access: yesIntegrative Zoology, EarlyView.
We study that browsing by wapiti reduces the growth of saplings, and it develop chemical defenses to prevent themselves browsed again. These results reduce our concern about wapiti browse T. cuspidate saplings, and provide basic data for the study of the interaction between them, and also provide theoretical basis for the population restoration and ...

Warm Spring Weather Alters Calling Phenology of Four Sympatric Early‐Breeding Anurans

open access: yesIntegrative Zoology, EarlyView.
An unusually warm March in 2024 (“false spring”) followed by freezing temperatures allowed us to assess the impact of a weather event on an amphibian community. The calling activity of all four species was associated with increasing temperature, and the first date of calling was advanced by 11–18 days.

From LiDAR point clouds to 3D tree morphometrics: New approach to quantitatively evaluate tree shapes

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Tree crowns are complex, three‐dimensional structures whose morphology varies among species, individuals and environments. Although light detection and ranging (LiDAR) provides high‐resolution, single‐tree point clouds that advance species discrimination and the assessment of intraspecific variation in situ, crown shape is still commonly ...

Seasonal Habitat Selection by a Threatened Ungulate in an Industrializing Boreal Landscape

open access: yesAnimal Conservation, EarlyView.
Understanding habitat selection by Threatened wood bison in landscapes characterized by anthropogenic disturbance is important for conservation planning. During summer and winter, bison selected for linear (e.g., roads, seismic lines, pipelines) and polygonal (e.g., well sites) disturbances, unless there were high densities of linear features.
