Gone with the forest: Assessing global woodpecker conservation from land use patterns [PDF]

open access: yes, 2018
As a result of their ecological traits, woodpeckers (Picidae, Aves) are highly sensitive to forest cover change. We explored the current land cover in areas of high species richness of woodpeckers to determinate regions where urgent conservation actions ...

Inconsistent effects of P enrichment and predator presence on food‐web dynamics in a bromeliad system

open access: yesOikos, EarlyView.
Food webs consist of trophic interactions of variable strength. However, it remains challenging to predict how changes in environmental conditions, such as nutrient enrichment, can affect these interactions. In this paper, we propose to integrate food web theory with ecological stoichiometry, which predicts how elemental ratios affect trophic ...

Floral trait similarity at the community‐level increases reproductive success suggesting facilitation through pollinator sharing

open access: yesOikos, EarlyView.
The ability of plants to attract pollinators is context‐dependent, influenced by floral traits, abundance, and resources from the plant community. Indirect interactions through shared pollinators, from competition to facilitation, may lead to varied reproductive outputs in plants, and the mechanisms behind these interactions remain to be fully ...
