Bee and butterfly populations are declining in North America due to environmental changes, with significant research gaps hindering conservation efforts.
In this study, Souther and colleagues used data compiled on four major families of bees and butterflies to construct species distribution models, enabling them to assess changes over time and space across North America. Comparisons with climate data indicate that these population changes are at least partly related to the impacts of recent climate change – such as prolonged drought and habitat degradation – and regions experiencing apparent population declines have also been heavily impacted by anthropogenic land use. The authors note too that the apparent increases in the eastern U.S.

Hornets found to be primary pollinators of two Angelica speciesResearcher Ko Mochizuki of the University of Tokyo discovered that two species in the genus Angelica are pollinated primarily by hornets. This overturns the conventional belief that Angelica species are 'generalists,' meaning that there is not one primary pollinator but a variety of species.

Unraveling differences in temperature sensitivity of soil organic matter decomposition under various oxygen conditionsSoil organic matter (SOM) decomposition is a key process that affects soil carbon storage and greenhouse gas emissions. Investigating the temperature sensitivity (Q10) of SOM decomposition and its regulating mechanisms is important for improving predictions of SOM stability and carbon fluxes under future warming.
