Marine trophic architecture and hidden ecological connections in the Strait of Magellan: keystone species and ecosystem resilience

open access: yesOikos, EarlyView.
Understanding the ecological implications of species coexistence is central to biodiversity studies and to identify environmental and anthropogenic drivers of ecosystem dynamics, where ecological network analysis offers valuable insights. This study examines the complexity, structure, and potential responses to disturbances of the Strait of Magellan's ...

Floral resource diversity drives spatiotemporal variation in plant–pollinator network structure

open access: yesOikos, EarlyView.
Mechanisms underlying community assembly, including those related to species interactions, vary across space and time. Plant–pollinator networks exemplify these dynamics, where link rewiring and turnover mediate adaptations to environmental changes. Bees rely on diverse floral resources (e.g.

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 ...
