Tell me where you flow and I will tell you who you are: basin context shapes the insect fauna of small tributaries

open access: yesOikos, EarlyView.
The traditional view of river basins as linear corridors has led to numerous studies examining the effects of stream size on aquatic communities. However, similar‐sized streams may harbor distinct faunal assemblages depending on their spatial context within the basin. Headwater tributaries (HTs) that flow into small streams, in the periphery of basins,

Greater future range expansions in alien than native ant species

open access: yesOikos, EarlyView.
There is growing concern that many species may not be able to track suitable conditions under climate change and suffer range contractions as a result. At the same time, alien species introduced to novel geographic ranges are often assumed to benefit from climate change.

Familiarity and aggression shape long‐term associations and mortality risk in a solitary ungulate

open access: yesOikos, EarlyView.
Periodic social interactions are important to animal fitness, even in solitary species. For solitary species, these interactions can be unexpected and shaped by previous encounters. Despite being aggressive and largely solitary, black rhinoceroses Diceros bicornis are commonly seen in groups, suggesting they may engage in more social behaviours than ...

When wolves aren't enough: revisiting trophic cascades in northern Wisconsin

open access: yesOikos, EarlyView.
Elimination of top predators has allowed large herbivores to flourish in many terrestrial ecosystems, transforming food webs and ecosystem functions. Restoration of large predator communities is hoped to reverse negative effects of this trophic downgrading, but evidence for such effects is elusive.

Dress for success: climate pressures predict fur insulation and body size in natural and reintroduced populations of a threatened marsupial

open access: yesOikos, EarlyView.
Phenotypic variation in functional traits underpins responses to environmental gradients, influencing thermoregulation, energy balance, and long‐term persistence under climate extremes. Climate change is altering these gradients globally, yet in species that have already disappeared from much of their range, adaptive phenotypes may have also been lost,
