Forest and fire drive moose (deníe) detections near their northern range limit

Wildlife Biology, EarlyView.
One way to understand species range shifts in response to anthropogenic climate change is to study populations living at the limit of climate and resource suitability. Moose Alces alces (deníe in Dënesųłıné) generally require forest–wetland landscape complexes but are increasingly seen across the forest–tundra transition at their northern range limit ...

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

Journal 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

The 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

Insect 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

Insect 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

Integrative 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 ...

Forest under stress: responses and recovery of water relations across scales during the compound drought in summer 2022. [PDF]

New Phytol
A schematic showing the links of tree‐scale (root‐, stem‐, and leaf‐level) and ecosystem‐scale water relations during the CSAD at CH‐Lae. Summary The summer of 2022 was characterized by compound soil and atmospheric drought (CSAD; low soil water content, SWC, and high vapor pressure deficit, VPD) in Central Europe, threatening forest carbon ...

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

Integrative 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.

Mechanisms of resistance of white spruce to the spruce bud moth

The Forestry Chronicle, 1996
There is a genetic basis to resistance of open-grown white spruce trees to their primary pest, the spruce bud moth, Zeiraphera canadensis Mutt. & Free. Resistance is attributable to late budburst and unknown factors associated with higher predation and parasitism of eggs and mortality of old larvae.
