Rat snakes, cowbirds, and vines lower passerine nest survival in remnant bottomland hardwood forests in east-central Arkansas, USA

Avian Conservation and Ecology, 2021
Predation is often the leading cause of nest failure among passerines; however, specific causes are often unknown or can be misidentified in the field.

Nest Predation Pressure Differs Between Urban Ground- and Hole-Nesting Birds: Evidence from a Multi-Year Artificial Nest Predation Experiment

Birds
Urbanization changes the environment through physical constructions, disturbances, and altered resource availability. These modifications influence both prey and predator assemblages.

Identification of predation events in wild fish using novel acoustic transmitters

Animal Biotelemetry, 2020
Background Acoustic telemetry is a commonly used tool to gain knowledge about aquatic animal ecology through the study of their movements. In telemetry studies researchers must make inferences regarding the movements and the fates of tagged animals ...

Predation domes: In‐situ field assays to measure predatory behaviours by fish

Methods in Ecology and Evolution, 2023
Biotic interactions such as predation are difficult ecological processes to quantify in the wild. This is especially the case in the marine environment due to logistical difficulties in capturing animal behaviour.

Maternal predator‐exposure affects offspring size at birth but not telomere length in a live‐bearing fish

Ecology and Evolution, 2020
The perception of predation risk could affect prey phenotype both within and between generations (via parental effects). The response to predation risk could involve modifications in physiology, morphology, and behavior and can ultimately affect long ...

Camouflage in predators [PDF]

Biological Reviews, 2020
ABSTRACTCamouflage – adaptations that prevent detection and/or recognition – is a key example of evolution by natural selection, making it a primary focus in evolutionary ecology and animal behaviour. Most work has focused on camouflage as an anti‐predator adaptation. However, predators also display specific colours, patterns and behaviours that reduce

Species‐ and origin‐specific susceptibility to bird predation among juvenile salmonids

Ecosphere, 2023
Juvenile salmonids often experience high mortality rates during migration and bird predation is a common source of mortality. Research suggests that hatchery‐reared salmonids are more prone to predation than wild salmonids, and that Atlantic salmon ...

Field margins enhance weed seed predation in adjacent fields in early spring

Frontiers in Agronomy, 2023
Seed depletion by granivorous organisms can regulate weeds in arable agriculture. Enhancing this regulation can be achieved by adopting farming practices that favour seed predators.

MOGAD Is the Most Common Cause of Isolated Optic Neuritis in Children

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives The study aimed to characterize the clinical features, etiologies, and outcomes of isolated, first‐time pediatric ON in the post‐MOG‐IgG era. Methods This was a single‐center retrospective cohort study at Texas Children's Hospital of patients diagnosed with first‐time ON between 2018–2024, with follow‐up data collected through 2025.

Predation of eggs and incubating females in willow ptarmigan Lagopus l. lagopus

Fauna Norvegica
Nest predation is a major cause of reproductive loss in many ground-nesting birds. During 15 consecutive years the predation of nests and females throughout the incubation season were recorded in a willow ptarmigan Lagopus l.
