Sound categorization by crocodilians

open access: yesiScience, 2023
Summary: Rapidly sorting the information contained in a stream of stimuli is a major challenge for animals. One cognitive mechanism for achieving this goal is categorization, where the receiving individual considers a continuous variation of a stimulus ...

From anecdotes to evidence: Environmental DNA detection of Arctic charr (Salvelinus alpinus L.) at the southern limit of its circumpolar range

open access: yesJournal of Fish Biology, EarlyView.
Abstract The urgency of rapid species monitoring is at an all‐time high due to the increasing threat of climate change to global ecosystems, in particular freshwater habitats. Fish such as Arctic charr, Salvelinus alpinus, are particularly vulnerable to increasing water temperatures and changes in land use due to their dependence on cold waters and ...

Occipital bone modeling patterns during the first years of life: A preliminary histological and quantitative approach

open access: yesJournal of Anatomy, EarlyView.
Modeling maps of the endocranial surface. Orange color indicates resorption fields, blue color deposition. Dashed lines indicate that the pars lateralis and pars basilaris have not yet fused. Abstract Studies of modeling processes have provided important insights in human evolutionary discipline.

INSECT FLIGHT - BIOACOUSTICAL APPROACH

open access: yesLe Journal de Physique Colloques, 1990
Insect aerodynamics is drawing the attention of a number of researchers belonging to different disciplines with a view to understand its aerodynamic capabilities so as to revolutionise the aircraft technology. It is possible to understand, to some extent, the insect aerodynamics by experimentally determining the frequency of wing beat in its fethered ...

Individual Discrimination Within, but Not Between, Two Vocalization Types of the Black‐Capped Chickadee

open access: yesEthology, Volume 131, Issue 8, Page 1-12, August 2025.
Black‐capped chickadees' chick‐a‐dee calls and fee‐bee songs are individually distinct. We used an operant conditioning Go/No‐go paradigm to train chickadees to discriminate among four individuals' chick‐a‐dee calls or fee‐bee songs. Chickadees successfully learned this discrimination rule.

Anthropogenic noise and the bioacoustics of terrestrial invertebrates

open access: yesJournal of Experimental Biology, 2019
Anthropogenic noise is an important issue of environmental concern owing to its wide-ranging effects on the physiology, behavior and ecology of animals. To date, research has focused on the impacts of far-field airborne noise (i.e.

Gene Expression Shifts in Emperor Penguin Adaptation to the Extreme Antarctic Environment

open access: yesMolecular Ecology, Volume 34, Issue 15, August 2025.
ABSTRACT Gene expression can accelerate ecological divergence by rapidly tweaking the response of an organism to novel environments, with more divergent environments exerting stronger selection and supposedly, requiring faster adaptive responses. Organisms adapted to extreme environments provide ideal systems to test this hypothesis, particularly when ...
