Land use, local management, and seasonal variation significantly impact the ecological dynamics of bee–plant communities their interactions. These variables negatively affect diversity interaction networks within human-dominated landscapes. Additionally, such as temperature, rainfall, resource availability across different seasons play essential roles in shaping bee interactions with flowering plants. However, little is known about how non-crop plants agricultural landscapes respond to intra-seasonal variations, specifically rainy season.

We analysed the wild bee community sampled from 1921 to 2018 at a nature preserve in southern Michigan, USA, study long-term shifts protected area. During an intensive survey 1972 and 1973, Francis C. Evans detected 135 species. In most recent surveys conducted 2017 2018, we recorded 90 Only 58 species were both sampling periods, indicating significant shift community. found that diversity, richness evenness all lower samples. Additionally, 64% of more common exhibited than 30% decline relative abundance. Neural network analysis traits revealed extirpation reserve was likely for oligolectic ground-nesting bees kleptoparasitic bees, whereas polylectic cavity-nesting persist. Having longer phenological ranges also increased chance persistence Further suggests climate response as contemporary period had southerly overall distribution compared historic Results exhibit utility data machine learning disentangling complex indicators population trajectories.
