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

Oikos, 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.

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

Oikos, 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.

Bottom–up and top–down drivers influence urbanization effects on insect herbivory in oaks

Oikos, EarlyView.
Urban forests provide essential ecosystem services, including pest control, biodiversity conservation, and human health benefits. Herbivory is a widespread biotic interaction that shapes ecosystem functions, such as primary productivity and soil fertility, which underpin these services.
