Nesting habitat of ground‐nesting bees: a review

Bees: Their Nests and Nesting Sites

Terrestrial habitat requirements of nesting freshwater turtles

Because particular life history traits affect species vulnerability to development pressures, cross-species summaries of life history traits are useful for generating management guidelines. Conservation of aquatic turtles, many members of which are regionally or globally imperiled, requires knowing the extent of upland habitat used for nesting. Therefore, we compiled distances that nests and gr...

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,...

Snags as Indicators of Habitat Suitability for Open Nesting Birds

--The habitat requirements of open nesting birds were examined in 19, five hectare, plots arranged along an altitudinal gradient in western Montana. Seven, mature forest birds were examined in detai 1. Percent shrub and low canopy cover {0.5-1.5m), mid-canopy cover {8-25m), and the number of large diameter stems {25-50 em dbh) were of major importance to this avian co11111unity. Increased avian...

Responses of Nesting Bobolinks (Dolichonyx oryzivorus) to Habitat Edges

-Avoidance of habitat edges may be contributing to reduced densities of grassland birds in small habitat patches. Nest densities for grassland-nesting Bobolinks (Dolichonyx oryzivorus) were much lower than expected within 25m of forest edges at three sites in New York, and that pattern ("edge avoidance") extended to 100m at one site. Nests located within 50 m of forest or wooded hedgerow edges ...
