Abstract: Habitat fragmentation has been shown to influence the abundance, movements, and persistence of many species. We asked the following questions: (1) Do species respond mainly to habitat loss or to the changes in habitat configuration resulting from this loss? (2) Do species exhibit sharp thresholds in their response to forest cover or configuration? We compared the relative influence of forest cover and configuration on 15 bird species in 33 landscapes (6.25 km2) in eastern Ontario… 

Effects of Landscape Structure on Nesting Songbird Distribution in a Harvested Boreal Forest

We studied the effects of forest cover and configuration on nesting songbird distribution in a harvested boreal forest. To emphasize landscape-level effects relative to stand effects, point count

Thresholds in forest bird richness in response to three types of forest cover in Ontario, Canada

AbstractContextIdentification of threshold values in avian responses to habitat loss provides science-based guidelines on how to best manage anthropogenically altered landscapes for wildlife

Loss and fragmentation of mature woodland reduce the habitat niche breadth of forest birds

Regional abundance and, in turn, density-dependent spillover into suboptimal habitat appeared to be determinants of habitat niche breadth, which appeared to drive the response to loss and fragmentation of mature woodland.

Associations of Forest Cover, Fragment Area, and Connectivity with Neotropical Understory Bird Species Richness and Abundance

The results demonstrated a rapid loss of species at relatively high levels of forest cover (30-50%) and highly sensitive species were 3-4 times more common above the 30-50% threshold than below it; however, the results do not support a unique fragmentation threshold.

Relationships Between Landscape Structure and Breeding Birds in the Oregon Coast Range

This work investigated the relationship between landscape structure and breeding bird abundance in the central Oregon Coast Range and found that species' abundances were generally greater in the more heterogenous landscapes; that is, they were associated with the more fragmented distribution of habitat.

ARE BOREAL BIRDS RESILIENT TO FOREST FRAGMENTATION? AN EXPERIMENTAL STUDY OF SHORT‐TERM COMMUNITY RESPONSES

No significant change in species richness was detected as a result of the harvesting, except in the 1-ha connected fragments, where the number of species increased two years after isolation, suggesting that the adjacent buffer strips were being used as movement corridors.

Relative Effects of Habitat Loss and Fragmentation on Population Extinction

It is suggested that details of how habitats are arranged cannot usually mitigate the risks of habitat loss, and conservation efforts should be aimed foremost at stopping habitat loss and at habitat restoration.

Dynamics in subdivided populations of neotropical migratory birds in a fragmented temperate forest

It is suggested that site fidelity might be an important constraint on the distributional dynamics of these species, even when effects of fragment area and habitat on site fidelity are factored out.

Effect of changes in regional forest abundance on the decline and recovery of a forest bird community

Bird populations were monitored for 32 years in a 23-ha tract of hemlockhardwood forest. Between 1953 and 1976 the total abundance of long-distance migrants declined significantly and four species

Effects of habitat fragmentation on birds and mammals in landscapes with different proportions of suitable habitat: a review

Simulations of patterns and geometry of landscapes with decreasing proportion of the suitable habitat give rise to the prediction that the effect of habitat fragmentation on e.g. population size of a species would be primarily through habitat loss in landscape with a high proportion of suitable habitat.

Habitat availability causes the species abundance-distribution relationship

A positive correlation between abundance and the number of breeding habitat cells on the simulation landscape and distribution is found, suggesting that differences in amount of available habitat could account for a positive relationship between distribution and abundance.

Metapopulation persistence of an endangered butterfly in a fragmented landscape

It is demonstrated that this system satisfies the four necessary conditions for a species to persist in a balance between stochastic local extinctions and recolonizations, and is the first conclusive demonstration of declining habitat occupancy and hence of increasing threat to survival caused by increasing habitat fragmentation.

Use of Riparian Buffer Strips as Movement Corridors by Forest Birds

We conducted a 3-year field experiment to measure the frequency of bird movements through riparian buffer strips before and after harvesting of adjacent forest. Our study was conducted in the boreal

Landscape-scale examination of parasitism patterns of Brown-headed Cowbirds (Molothrus ater) revealed heterogeneous parasitism rates across the mosaic of a forest and associated old-field
