Evaluation of factors associated with predation on Caiman latirostris nests (Crocodylia: Alligatoridae) in Argentina [PDF]

open access: yesPhyllomedusa: Journal of Herpetology, 2016
Predation is a major cause of crocodilian egg loss. However, at present, the mechanisms by which predators detect nests is unknown. Previous studies have reported that predators are able to detect prey using both visual and olfactory cues.

Predation Cues in Solitary bee Nests [PDF]

open access: yesJournal of Insect Behavior, 2017
Predation at the nesting site can significantly affect solitary bees' reproductive success. We tested female red mason bees' (Osmia bicornis L.) acceptance of potential nesting sites, some of which were marked with cues coming from predated conspecifics (crushed bees) or from a predator itself (rodent excreta).

Breeding phenology of birds: mechanisms underlying seasonal declines in the risk of nest predation. [PDF]

open access: yesPLoS ONE, 2013
Seasonal declines in avian clutch size are well documented, but seasonal variation in other reproductive parameters has received less attention. For example, the probability of complete brood mortality typically explains much of the variation in ...

Contrast in edge vegetation structure modifies the predation risk of natural ground nests in an agricultural landscape. [PDF]

open access: yesPLoS ONE, 2012
Nest predation risk generally increases nearer forest-field edges in agricultural landscapes. However, few studies test whether differences in edge contrast (i.e.

Artificial nest predation rates vary depending on visibility in the eastern Brazilian Amazon [PDF]

open access: yesActa Amazonica, 2014
Observational and experimental studies have shown that increased concealment of bird nests reduces nest predation rates. The objective of the present study was to evaluate differences in predation rates between two experimental manipulations of ...

Do Freshwater Turtles Use Rainfall to Increase Nest Success?

open access: yesFrontiers in Ecology and Evolution, 2022
Rainfall following turtle nest construction has long been believed to increase nest survival by its effects on reducing the location cues used by nest predators.

Multiple stressors: negative effects of nest predation on the viability of a threatened gull in different environmental conditions

open access: yesJournal of Avian Biology, 2022
The majority of the world's seabirds show substantial population declines, but a detailed understanding of the phenomenon is lacking. A potentially important mechanism that has received momentum lately is nest predation.

Nest predation in Afrotropical forest fragments shaped by inverse edge effects, timing of nest initiation and vegetation structure [PDF]

open access: yes, 2014
High levels of nest predation influence the population dynamics of many tropical birds, especially when deforestation alters nest predator communities. The consequences of tropical forest fragmentation on nest predation, however, remain poorly understood,

Predator identity influences the effect of habitat management on nest predation [PDF]

open access: yesEcological Applications, 2015
Predation is the leading cause of nest failure for many passerines and considerable effort is devoted to identifying the habitat characteristics and management practices that influence nest loss. The habitat components associated with nest loss are strongly influenced by the ecology of nest predators and differ among predator species as a result ...

Landscape effects on nest site selection and nest success of Northern Lapwing Vanellus vanellus in lowland wet grasslands [PDF]

open access: yes, 2016
Capsule: Northern Lapwing Vanellus vanellus avoid nesting close to small woodland patches but nest predation rates do not vary with distance to woodland patches, either because risky areas are avoided or perceived nest predation risk does not reflect ...
