Ecological Exposure History Shapes Giraffe Vigilance Responses to Anthropogenic Noise: A Multisite Playback Experiment

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
Understanding how animals respond to anthropogenic disturbance is essential for predicting the impacts of human activity on wildlife behavior and persistence. As noise increasingly alters sensory landscapes across ecosystems, it can influence how animals detect threats and assess risk.

Acoustic Characteristics of Stridor in Multiple System Atrophy. [PDF]

open access: yesPLoS ONE, 2016
Nocturnal stridor is a breathing disorder prevalent in patients with multiple system atrophy (MSA). An improved understanding of this breathing disorder is essential since nocturnal stridor carries a poor prognosis (an increased risk of sudden death). In

Amphibian Chytrid Fungus Infection Influences Calling Investment in Male Brown Toadlets

open access: yesEcology and Evolution, Volume 15, Issue 10, October 2025.
The sublethal effects of infection and disease on male advertisement behaviour remain poorly understood. Here we show that male brown toadlets infected with the amphibian chytrid fungus produce calls with more pulses compared to uninfected males. The association we report supports the terminal investment hypothesis and has the potential to impact host ...
