Effects of roadside edge on nest predators and nest survival of Asian tropical forest birds

Global Ecology and Conservation, 2018
Creation of roadside forest edges can have indirect effects on forest bird communities, as edges can promote species detrimental to forest-nesting birds such as nest predators.

Sanitizing the fortress: protection of ant brood and nest material by worker antibiotics [PDF]

, 2013
Social groups are at particular risk for parasite infection, which is heightened in eusocial insects by the low genetic diversity of individuals within a colony. To combat this, adult ants have evolved a suite of defenses to protect each other, including

Residency patterns and apparent survival in a cavity-nesting bird: population consequences of nest-box supplementation revealed by a long-term study

Avian Conservation and Ecology, 2021
Phenotypic plasticity may help organisms persist in modified habitats. Yet, its adaptive value is frequently ignored because fitness consequences are not explored at the required time scale.

Lack of effect of microhabitat charaacteristics on nest predation and brood parasitims in creamy-bellied thruss (Turdus Amaurochalinus) [PDF]

, 2013
Nest predation and brood parasitism are key factors affecting nest survival in passerine birds. As a result, birds may select nest sites that minimize the probability of nests being found by predators or by brood parasites. Nevertheless, evidence remains

The relationship of telomere length to baseline corticosterone levels in nestlings of an altricial passerine bird in natural populations [PDF]

, 2015
Indexación: Web of Science; Scopus.Background: Environmental stressors increase the secretion of glucocorticoids that in turn can shorten telomeres via oxidative damage.

High breeding success of the European Starling compared to native species in a recently invaded natural forest of South America

Avian Conservation and Ecology, 2023
Invasive species present numerous threats to ecosystems as they compete with other species for resources and displace them from their habitats. One of the most invasive birds is the European Starling (Sturnus vulgaris), which recently invaded and started

A guide to nestling development and aging in altricial passerines [PDF]

, 2007
Nestling growth and development studies have been a topic of interest for a greater part of the last century (Sutton 1935, Walkinshaw 1948) and continue to be of interest today. This is not surprising since studies on nestling growth can provide a wealth

Ecological consequences of colony structure in dynamic ant nest networks [PDF]

, 2017
Access to resources depends on an individual’s position within the environment. This is particularly important to animals that invest heavily in nest construction, such as social insects.

Suboptimal conditions lead to differences in habitat use and nest survival of imperiled tidal marsh sparrows between an urban marsh and nearby non-urban island

Avian Conservation and Ecology
Sea level rise and human development are threatening the extinction of some saltmarsh birds. Nests risk failure because of flooding when built low to the ground, but taller nests face increased predation risk.
