Greater future range expansions in alien than native ant species

Oikos, 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.

Warming modifies trophic impacts of invading shrimp with impact varying among primary producers

Oikos, EarlyView.
Environmental change drivers, such as climate change and species invasions, can disrupt biological networks and weaken ecosystem stability. Acting together, these drivers may interact and alter the effects on the ecosystem. However, few studies have examined the interactive effects of climate change and species invasions, particularly in aquatic ...

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.

Piecewise structural equation modelling in ecology: common pitfalls and best practices for causal inference

Oikos, EarlyView.
Structural equation modelling (SEM) has become a cornerstone tool in ecology for testing hypotheses about causal relationships and disentangling direct and indirect effects. However, its growing use has led to frequent conceptual and methodological misapplications.

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 (
