Maternal health status correlates with nest success of leatherback sea turtles (Dermochelys coriacea) from Florida. [PDF]

PLoS ONE, 2012
Of the seven sea turtle species, the critically endangered leatherback sea turtle (Dermochelys coriacea) exhibits the lowest and most variable nest success (i.e., hatching success and emergence success) for reasons that remain largely unknown.

Previous reproductive success informs nest-building decisions

Behavioral Ecology
Abstract Behavioral outcomes, including foraging efficiency and reproductive success, often improve with age and with repeated breeding attempts. Here we examined the role of previous experience on the nest-building behavior of wild blue tits Cyanistes caeruleus.

Mallard Use of Hen HousesTM in Eastern Ontario

Avian Conservation and Ecology, 2006
Nesting structures for ground-nesting waterfowl may be an effective technique for increasing nesting success in regions in which nest success is below the 15% threshold needed to maintain a stable population.

Quantifying the Detrimental Impacts of Land-Use and Management Change on European Forest Bird Populations [PDF]

, 2013
The ecological impacts of changing forest management practices in Europe are poorly understood despite European forests being highly managed. Furthermore, the effects of potential drivers of forest biodiversity decline are rarely considered in concert ...

Quantifying multiple breeding vital rates in two declining grassland songbirds

Avian Conservation and Ecology, 2021
Many studies of reproductive success in North American songbirds have focused on nesting success, while relatively few have evaluated breeding-season adult survival and post-fledging survival.

Conditional female strategies influence hatching success in a communally nesting iguana

Ecology and Evolution, 2020
The decision of females to nest communally has important consequences for reproductive success. While often associated with reduced energetic expenditure, conspecific aggregations also expose females and offspring to conspecific aggression, exploitation,
