Playing with fire: Wolf response to active wildfires, fire fronts and smoke

open access: yesJournal of Animal Ecology, EarlyView.
This study is one of the first, to our knowledge, to explicitly examine fine‐scale behavioural responses of a large carnivore to actively burning wildfires, fire fronts and smoke. The study found that wolves balanced the potential risks and benefits associated with wildfires, with implications for predator–prey dynamics in fire‐prone regions.

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.

A Bark Thickness Model for White Spruce in Alaska Northern Forests

open access: yesInternational Journal of Forestry Research, 2009
Here we developed a simple linear model to estimate white spruce bark thickness in the northern forests of Alaska. Data were collected from six areas throughout interior and southcentral Alaska.

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.

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.
