1. Effects of resource availability on foraging trip duration in the silver bee, Habropoda miserabilis

Monroe, Jane,

Habitat fragmentation can have negative effects throughout an ecosystem, but its impact is dependent on the spatial scale at which community members respond to the environment. Because solitary bees a...
