Diet seasonality and resource partitioning by large catfishes in the Madeira River, Brazil

Acta Amazonica
Large catfishes form a diverse group with complex life histories, different habitat requirements and home range sizes, which may be related to several ecological aspects.

Trait convergence under warming: drought tolerance, not thermal limits, mediates native–invader dynamics in alpine ecosystems

Oikos, EarlyView.
Climate warming and plant invasions jointly alter alpine ecosystems, but the mechanisms underlying these interactions remain unclear. A key to predicting ecosystem vulnerability is whether native and invasive species can sustain performance as conditions warm.

Coexisting ant species differ in ability to meet their intrinsic nutritional needs

Oikos, EarlyView.
Coexisting species are often assumed to reduce competition by foraging for foods that differ in nutrient composition, but few studies test whether field nutritional differences correspond to intrinsic differences in macronutrient selectivity. We compared field estimates of worker trophic position (tissue isotopes: δ15N) and worker tissue stoichiometry (

Life‐history traits and phylogeny structure taxon‐specific species–substrate relationships in deadwood

Oikos, EarlyView.
To understand the structuring of species assemblages, integrating life‐history traits and evolutionary heritage in analyses is vital. This allows the assessment of a mechanistic link between species and their environment. Deadwood systems are vital for nutrient cycling and biodiversity support, governed by complex intra‐ and inter‐specific fungal and ...

Warming and predation drive rapid evolution of ecosystem functioning but not functional traits

Oikos, EarlyView.
Global environmental change can rapidly reshape phenotypic trait distributions through adaptive and neutral processes. Yet, disentangling their relative contributions remains a major challenge, particularly for traits underpinning ecosystem functioning.

Ecosystem engineers and functional dominance: when species loss matters for ecosystem function

Oikos, EarlyView.
Understanding when and why species loss affects community function in natural communities remains an open question in ecology. Recent cross‐system analyses have shown that functional dominance is associated with whether species loss matters: in communities dominated by few high‐performing species, lost species contribute little to function.

Characteristics of the diet of the western barn owl and the little owl in the Zakarpattia Oblast (Ukraine)

Theriologia Ukrainica
The article presents the results of an analysis of approximately 150 pellets (containing 178 food items) of the Little Owl (Athene noctua) and about 300 pellets (containing 1,268 food items) of the Barn Owl (Tyto alba) collected in the Berehove District,

Declines in the diversity of fish represented in British domestic recipes over the past 100 years

People and Nature, EarlyView.
Abstract Fish and shellfish are nutritionally important foods, yet consumption in many high‐income countries remains low and concentrated on a narrow set of environmentally costly species. In the United Kingdom, fish consumption is dominated by a small group of fish, the ‘Big Five’, which is often treated as an inevitable outcome of supply, convenience

Emotional costs and empathy are associated with tolerance towards wolves

People and Nature, EarlyView.
Abstract The recovery and growing population of grey wolves (Canis lupus) in Germany has increased interactions with livestock owners. Ensuring the continued protection and survival of wolves requires understanding the socio‐psychological factors that shape people's tolerance towards coexisting with them.
