Pruning slash drives ambrosia beetle (Curculionidae: Scolytinae, Platypodinae) activity in Khaya grandifoliola C.DC.: Slash removal as a preventive management strategy Resíduos de poda aumentam a atividade de besouros da ambrosia (Curculionidae: Scolytinae, Platypodinae) em Khaya grandifoliola C.DC.: A remoção dos resíduos como estratégia preventiva de manejo

open access: yesAgricultural and Forest Entomology, EarlyView.
Slash retention increased ambrosia beetle activity in Khaya grandifoliola, acting as both breeding substrate and source of attractive volatile cues that promoted localized population buildup. Beetle attacks occurred only near retained slash, while no attacks were recorded in slash‐removal plots, demonstrating that residue removal effectively prevents ...

Taxonomic and functional diversity of urban bees of the world

open access: yesConservation Biology, EarlyView.
Abstract Bees play a pivotal role in terrestrial environments. Urbanization can affect these organisms and the ecosystem services they provide. However, knowledge of the global diversity of urban bees is limited. Thus, we summarized data on urban bee species identities and occurrences; compared distributions of all bees with those found in urban ...

Evaluating a structured expert elicitation approach for adaptive conservation management based on lessons from five years in practice

open access: yesConservation Biology, EarlyView.
Abstract Adaptive management of threatened species relies on having ex ante estimates of species’ responses to different interventions. Structured expert elicitation is often used to generate these estimates, but comparisons of these expert‐predicted outcomes with observed results are rare.

Forest edges buffer effects of agricultural management on bee–plant interaction networks

open access: yesEcological Entomology, EarlyView.
Agricultural management effects: Organic and conventional crop margins host similar bee and plant species, but network structure differs: organic farms exhibit higher interaction diversity, conventional farms higher connectance. Role of forest edges: Native forest edges stabilize bee–plant networks by providing continuous floral resources and suitable ...
