Alignment, Rising, Sticking, and Phototaxis: Modulating the Behavior of Hematite Micropeanuts

Advanced Materials Interfaces, Volume 12, Issue 9, May 5, 2025.
Although a rich variety of behaviors, such as rising and phototaxis, are observed with light‐activated semiconductor microparticles, the experimental conditions under which such behaviors occur have not been elucidated. In this study, pH, fuel concentration, and light intensity are varied, revealing diverse behaviors of hematite microparticles.

Introduction. Ageing time beings: Temporality and ethics in old ages Introduction. Des êtres temporels vieillissants : temporalité et éthique du grand âge

Journal of the Royal Anthropological Institute, Volume 31, Issue S1, Page 5-18, April 2025.
What can we learn about temporality by studying different ways of measuring time, institutional time regimes, and (a)typical experiences and creations of time when growing older? This introduction sets perspectives on this question from the anthropologies of ageing, ethics, and temporality.

Quantifying the predation impact of an expanding mesocarnivore on declining small‐game species

Journal of Zoology, Volume 325, Issue 1, Page 80-91, January 2025.
We estimated the predation impact of the Egyptian mongoose (Herpestes ichneumon), an expanding mesocarnivore in southwestern Europe, on two declining prey species highly valued by hunters: European rabbit (Oryctolagus cuniculus) and red‐legged partridge (Alectoris rufa).

A new double observer‐based census framework to improve abundance estimations in mountain ungulates and other gregarious species with a reduced effort

Ecological Solutions and Evidence, Volume 5, Issue 4, October–December 2024.
We here propose a new census framework for mountain ungulates and other gregarious species, the Double Observer Adjusted Survey (DOAS). DOAS is based on total block counts adjusted with some Double Observer surveys to estimate detectability. The DOAS method could produce reliable abundance estimates, lowering the full double observer census efforts ...
