How much sampling is enough? Four decades of understorey bird mist‐netting across Amazonia define the minimum effort to uncover species assemblage structure

open access: yesIbis, EarlyView.
Mist‐net sampling comprises a key methodological component of assemblage‐wide avifaunal studies, particularly in the understorey of closed‐canopy tropical forests. To investigate mist‐net bird captures and species assemblage structure, we compiled data from 312 sites across the Pan‐Amazon.

Effect of land use change on Melolonthidae (Coleoptera: Scarabaeoidea) beetle communities in the deforestation arc of the Brazilian Amazon

open access: yesInsect Conservation and Diversity, EarlyView.
Habitat transformation in Amazon due to agriculture expansion impairs Melolonthidae diversity. Assemblage response towards habitat transformation are group‐dependent. Although highly disturbed, Amazon arc of deforestation region dwells sensitive insect assemblages. Abstract Although the Amazon provides crucial goods and ecosystem services for humanity,

Premature pollen development hinders autonomous self-pollination and promotes insect pollination in soybean (Glycine max L.)

open access: yesScientific Reports
Flower traits (e.g., self-compatibility) determine pollinator dependence, and thereby seed production and mating. But crop research often overlooks how specific flower traits influence pollination quantity and quality and, consequently, yield.

Estimating wild bee population size with validated distance sampling

open access: yesInsect Conservation and Diversity, EarlyView.
Distance Sampling is a promising method to estimate population size but has never been validated on insects. We validated it on a honey bee population of known size. We applied Distance Sampling to three insular pollinators and found that estimates are consistent across days, match species phenology and reflect the expected influence of weather ...
