Losers and winners: responses of grassland arthropods to land‐use components

Oikos, EarlyView.
Intensified land‐use in grasslands reduces biodiversity, particularly affecting arthropod populations. However, responses of individual species vary depending on their ecological traits and habitat requirements. Some species may tolerate or even benefit from intensive land‐use, while others, particularly specialists or those with narrow niches, are ...

Resource quantity affects infection success and impacts of a microsporidian on hosts

Oikos, EarlyView.
Resource quantity in the environment often changes over time and influences the nutritional status of hosts that may encounter parasites. If resource availability significantly alters both infection success and within‐host growth of a parasite, fluctuations in resources may underlie the seasonal disease outbreaks that have been observed for some ...

Distilling food web dynamics: top–down and bottom–up drivers of extinction and trophic cascades

Oikos, EarlyView.
Quantifying population dynamics is a fundamental challenge in ecology and evolutionary biology, particularly for species that are cryptic, microscopic, or extinct. Traditional approaches rely on continuous representations of population size, but in many cases, the precise number of individuals is unknowable.

Overexploitation can counteract top‐down control and the paradox of enrichment in simple food chains

Oikos, EarlyView.
Because of its high abundance or its high feeding intensity, a consumer can overexploit its resource by consuming it on a shorter timescale than resource regeneration. While this short‐term overexploitation is widespread in nature, its general implications for biotic control patterns and ecosystem stability are not clear.

Ecosystem size reverses the effect of the spatial coupling between autotrophic and heterotrophic ecosystems

Oikos, EarlyView.
The flow of non‐living resources between autotrophic and heterotrophic ecosystems can impact their ecosystem function. However, ecosystem size is similarly known to influence ecological properties and it is uncertain how the size of coupled ecosystems mediates the effect of resource flows.
