Predation on dependent offspring (ie, offspring that depend on parents for care) forms a
critical source of natural selection that may shape a diversity of life history traits. Selection …

Predation is the main cause of nest failure among birds and, therefore, a strong selective
agent. To fully understand patterns of nest predation, determining the identities of nest …

Although the migration ecology of birds breeding in the Neotropics is still poorly studied
relative to that of their counterparts breeding at north-temperate latitudes, studies conducted …

Nest structure is thought to provide benefits that have fitness consequences for several taxa.
Traditionally, reduced nest predation has been considered the primary benefit underlying …

Ecologists have long hypothesized that fragmentation of tropical landscapes reduces avian
nest success. However, this hypothesis has not been rigorously assessed because of the …

Cavity-nesting vertebrates are an important component of biodiversity in tropical and
subtropical forests, but their persistence will increasingly depend on remnant trees in logged …

The study of avian nesting biology in North America and Europe has a long history, resulting
in an expansive and information‐rich literature. In contrast, the tropics have been relatively …

Mountains hold much of the world's taxonomic diversity, but global climate change threatens
this diversity by altering the distributions of montane species. While numerous studies have …

Aim Species interactions are assumed to be stronger closer to the equator. However,
numerous studies provided conflicting results and considerable controversy exists …

770—PeRSPectiveS in oRnitHology— auK, vol. 125 (2001: 39) stated that “while extra-pair
mating systems are the norm for temperate zone passerines, this is not true for tropical …
