The relative roles of in situ diversification and lineage dispersal underlying diversity patterns at the assemblage level

open access: yesOikos, EarlyView.
Speciation, extinction, and dispersal are the historical processes influencing the spatial distribution of lineages and strongly influence diversity patterns. Here, we apply a recently developed methodological approach to quantify the relative legacies in situ diversification history (i.e.

Structural stability of plant–pollinator interactions despite seasonal abundance of long‐tongued hawkmoths

open access: yesOikos, EarlyView.
Seasonal environmental cycles affect plant–pollinator interactions by altering plant phenology. Periods of low resource availability can filter pollinators and reduce the complexity of interaction networks, but the extent to which the functional morphology of pollinators influences such filtering remains unclear.

Multiple scales of fear: foraging behaviour of white‐naped jays in semiarid landscapes

open access: yesOikos, EarlyView.
Animals must constantly balance the need to find resources with the risk of predation. Not only avoiding direct encounters with predators but also assessing the overall risk of their environment using cues, social information or habitat traits at multiple spatial and temporal scales.

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.

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 ...
