Population declines of many avian species are often attributed to increased rates of nest
predation in fragmented landscapes, yet mechanisms underlying these effects have rarely …

We reviewed published literature to examine the effect of habitat fragmentation on avian
nesting success at three spatial scales (ie, edge, patch, and landscape scales). We …

I challenge (1) the assumption that habitat patches are natural units of measurement for
species richness, and (2) the assumption of distinct effects of habitat patch size and isolation …

Although habitat loss and fragmentation are widely regarded as major factors contributing to
the decline of many populations, the relative importance of each phenomenon is seldom …

The orientation and position of hard substrata used to test ecological hypotheses about
sessile marine plants and animals have often been based on logistical convenience. Much …

The idea that local factors govern local richness has been dominant for years, but recent
theoretical and empirical studies have stressed the influence of regional factors on local …

The notion that species might exhibit thresholds in their response to habitat alteration is
appealing from a conservation perspective. Such thresholds could be used as targets for …

Urban areas have been considered “safe zones” for nesting birds because of low
abundance of predators, and consequently low predation pressure. We studied risk of …

Summary 1 Predators impose costs on their prey but may also provide benefits such as
protection against other (eg nest) predators. The optimal breeding location in relation to the …

Urbanization processes transform landscapes worldwide, concentrating human population
and generating non-sustainable patterns of resource exploitation. Although nest predation is …
