Integrating host condition into spatiotemporal multiscale models improves virus shedding predictions
Ecography, EarlyView.Understanding where and when pathogens occur in the environment has implications for reservoir population health and infection risk. In reservoir hosts, infection status and pathogen shedding are affected by processes interacting across different scales: from landscape features affecting host location and transmission to within‐host processes affecting

Ecography, EarlyView.Land‐use changes and climatic changes are two entwined stressors on ecosystems. Studies on such interactions often focus on species‐level or region‐specific responses, but fewer have examined differences in responses based on functional traits. Here we examine the influence of natural habitat cover and temperature change on the abundance of all ...

Ecography, EarlyView.Niche partitioning is one of the key mechanisms allowing species coexistence and is especially relevant in species‐rich communities. For pollinators, morphology is a major axis in which species differentiate their foraging niche, as it influences the match with flower morphology. Bumblebees Bombus spp.

Future Postharvest and Food, EarlyView.ABSTRACT Bee pollen has been used as a medicine and food supplement. The biological activity and nutrient composition of bee pollen depend on its floral origin. Therefore, it was aimed to determine the phenolic and flavonoid content and antibacterial activities of methanolic (99.9%) extract of bee pollens among flora. Floral origin was identified using
