Habitat Fragmentation and Native Bees: a Premature Verdict?

Conservation Ecology: Habitat Fragmentation and Native Bees: A Premature Verdict?

Few studies directly address the consequences of habitat fragmentation for communities of pollinating insects, particularly for the key pollinator group, bees (Hymenoptera: Apiformes). Bees typically live in habitats where nesting substrates and bloom are patchily distributed and spatially dissociated. Bee studies have all defined habitat fragments as remnant patches of floral hosts or forests,...

‘Bee Hotels’ as Tools for Native Pollinator Conservation: A Premature Verdict?

Society is increasingly concerned with declining wild bee populations. Although most bees nest in the ground, considerable effort has centered on installing 'bee hotels'--also known as nest boxes or trap nests--which artificially aggregate nest sites of above ground nesting bees. Campaigns to 'save the bees' often promote these devices despite the absence of data indicating they have a positive...

Increased abundance of native and non-native spiders with habitat fragmentation

Habitat fragmentation and invasive species often contribute to the decline of native taxa. Since the penetration of non-native species into natural habitat may be facilitated by habitat fragmentation, it is important to examine how these two factors interact. Previous research documented that, in contrast to most other arthropod taxa, spiders increased in density and morphospecies richness with...

Habitat Loss and Fragmentation

Glossary Cover type A term used by the geographers for a type of mapped feature (e.g., forest, freshwater, or grassland). The dominant natural cover type in a landscape is often used to approximate habitat. Fragmentation per se The breaking apart of habitat while keeping habitat amount constant. Habitat The place where an organism normally lives. Habitat fragmentation The breaking apart of habi...
