European Pond Turtle (Emys orbicularis) Nest Predation: A Study with Artificial Nests

Biology, 2023
Nest predation significantly impacts the population decline of the long-living European pond turtle (Emys orbicularis). Kis-Balaton is one of the most important habitats of this species in Hungary, and in May 2017 more than 400 damaged nests were counted.

Nest survival of the Snowy Plover Charadrius nivosus at Marismas Nacionales, Nayarit

Huitzil, 2022
Breeding habitat loss and nest predation are considered the main causes of Snowy Plover (Charadrius nivosus) populations decline worldwide. We evaluated the effects of season, nest age, distance to nearest vegetation patch, distance to nearest body of ...

Effect of nest age and habitat variables on nest survival in Marsh Harrier (Circus aeruginosus) in a fishpond habitat [PDF]

PeerJ, 2020
Background One important anti‐predator strategy adopted by birds involves nest site selection and timing of breeding. Nest-site selection by marsh-nesting birds often involves nest concealment and water depth as key features influencing nest survival ...

Mammalian predators and vegetated nesting habitat drive reduced protected area nesting success of Kentish plovers, Yellow Sea region, China

Ecology and Evolution, 2023
Protected areas provide essential habitats for wildlife by conserving natural and semi‐natural habitats and reducing human disturbance. However, whether breeding birds vulnerable to nest predation can benefit from strict land management in the protected ...

Insights into the genetic covariation between harvest survival and growth rate in olive flounder (Paralichthys olivaceus) under commercial production environment

Aquaculture and Fisheries, 2023
In aquaculture, selective breeding for survival till harvest have become an alternative strategy for improving disease resistance and production. However, knowledge of genetic parameters of harvest survival, e.g., heritability and genetic correlations ...

The effectiveness and cost efficiency of different predator exclosure designs to increase piping plover (Charadrius melodus) nest success and fledging rate in Alberta, Canada

Conservation Science and Practice, 2023
An estimated 30% of the North American piping plover (Charadrius melodus) breeding population occurs in Canada, where it is Endangered. Predator exclosures are a common management tool across the species' range to increase nest success.

Variables associated with nest survival of Golden-winged Warblers (Vermivora chrysoptera) among vegetation communities commonly used for nesting

Avian Conservation and Ecology, 2015
Among shrubland- and young forest-nesting bird species in North America, Golden-winged Warblers (Vermivora chrysoptera) are one of the most rapidly declining partly because of limited nesting habitat.
