As a result of changes in natural and anthropogenic disturbance regimes, the extent of early-
successional forest across much of eastern North American is near historic lows, and …

Habitat quality of a bird's breeding grounds has been typically evaluated by investigating
patterns in nesting success, whereas events that follow fledging have been largely ignored …

Invasive smooth cordgrass (Spartina alterniflora, hereafter Spartina) has been expanding
rapidly in the estuarine wetlands at Chongming Dongtan (East China) at the expense of …

Urbanization is currently one the most important causes of biodiversity loss. The Colombian

Population models for many animals are limited by a lack of information regarding juvenile
survival. In particular, studies of songbird reproductive output typically terminate with the …

For most bird species, little is known about their ecology and survival between fledging and
independence despite the potential for post-fledging survival to be a factor limiting …

Populations of migratory bird species have suffered a sustained and severe decline for
several decades. Contrary to non-migratory species, understanding the causal mechanisms …

Recent studies have highlighted the importance of the post-fledging period to bird
populations, suggesting that the importance of this portion of the life cycle is equal to or …

Glucocorticoid hormones are an integral part of the vertebrate stress response, and
theoretical models argue for a link between glucocorticoid levels and individual fitness. The …

Despite the importance of seed dispersal for survival of plant species in fragmented
landscapes, data on seed dispersal at landscape scales remain sparse. Effective seed …
