Environmental drivers of wild bee reproductive performance across a South American dryland ecoregion.
The reproductive performance of wild bees is a key determinant of their population persistence. However, few studies have directly examined the environmental drivers of demographic processes using a geographically broad approach. In this study, we explored how biotic and abiotic factors influence the reproduction of solitary, cavity-nesting bees across the Monte Desert ecoregion in Argentina. Using artificial nests and a standardized sampling spanning 2000 km and 20° of latitude, we related key reproductive metrics-nest establishment, offspring production and offspring survival-to latitude, climate and biotic factors (flower abundance, vegetation cover and brood parasitism). Climate was the strongest predictor of bee reproductive performance: warm, humid conditions during the nesting period were associated with reduced nest establishment and offspring survival. Brood parasitism further reduced offspring survival. Across the Monte Desert's latitudinal gradient, nest establishment peaked at mid-latitudes, while offspring production and survival increased towards higher latitudes. These general patterns matched those of M. leucografa, the most abundant bee species. These findings highlight the sensitivity of wild bee reproduction to climatic conditions, particularly during the nesting period. Our study advances our understanding of the potential impacts of climate change on Neotropical wild bees, where extensive areas are experiencing dramatic land-use changes.
期刊介绍:
Proceedings B is the Royal Society’s flagship biological research journal, accepting original articles and reviews of outstanding scientific importance and broad general interest. The main criteria for acceptance are that a study is novel, and has general significance to biologists. Articles published cover a wide range of areas within the biological sciences, many have relevance to organisms and the environments in which they live. The scope includes, but is not limited to, ecology, evolution, behavior, health and disease epidemiology, neuroscience and cognition, behavioral genetics, development, biomechanics, paleontology, comparative biology, molecular ecology and evolution, and global change biology.
