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

open access: yesBiology, 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.

Nesting Success and Nest Predators in Forest Fragments: A Study Using Real and Artificial Nests [PDF]

open access: yesThe Auk, 2000
Abstract Area sensitivity in songbirds is commonly attributed to increased nest predation in forest fragments. In 1995 and 1996, we tested whether the nest predators and nesting success of an area-sensitive forest bird, the Eastern Yellow Robin (Eopsaltria australis), varied with fragment size, and we also conducted an artificial nest

Connectivity Explains Local Ant Community Structure in A Neotropical Forest Canopy: A Large‐Scale Experimental Approach [PDF]

open access: yes, 2019
Understanding how habitat structure and resource availability affect local species distributions is a key goal of community ecology. Where habitats occur as a mosaic, variation in connectivity among patches influences both local species richness and ...

Nest predation in the African blue tit Cyanistes teneriffae Lesson, 1831 (Aves, Paridae) . Using nest-boxes and artificial nests.

open access: yesZoodiversity, 2020
Predation on breeding blue tit populations in north-eastern Algeria has been studied in nest boxes during a five years fieldwork (2003-2007) in cork oak forests. Nest boxes were placed each year in Brabtia plain forest in El Kala National Park.

Do artificial nests reveal relative nest predation risk for real nests?

open access: yesJournal of Avian Biology, 2002
Present knowledge of the effects of nest predation on spatial distribution, habitat selection and community structure of birds is to a large extent based on results from experiments with artificial nests. Although nest predation risk is likely to differ between artificial and real nests, most previous studies of nest predation ...

Using Artificial Nests To Study Nest Predation IN BIRDS

open access: yesThe American Biology Teacher, 2005
A simple and effective field exercise that demonstrates factors affecting predation on bird nests is described. With instructor guidance, students in high school biology or college-level biology, ecology, animal behavior, wildlife management or ornithology laboratory courses can collaborate to design field experiments related to nest depredation.
