Colour change in Euleptes europaea: preliminary evidence for multifactorial environmental influence

Cindy Monnet, Théo Dokhelar, Julien Renet

Abstract Some ectotherms adjust their body colouration in response to environmental factors, supporting functions like thermoregulation or background matching. This study investigated the environmental drivers of physiological colour change in the European leaf-toed gecko ( Euleptes europaea ) under semi-natural conditions. Individuals …

Lost sites, lost signals: How non-random abandonment of sampling sites biases trends in biodiversity

Théo Dokhelar, Clément Calenge, Laurence Curtet, Jules Chiffard et autres

Long-term ecological monitoring is essential for tracking biodiversity trends and guiding conservation policy. However, these programs often experience changes in site coverage over time, through both the loss of existing sites and the addition of new ones. When this loss is non-random—corresponding …

Spring home range and spatiotemporal activity of Edward’s Sand Racer (Psammodromus edwarsianus) in a protected natural area of southern France

Julien Renet, Théo Dokhelar, Thierry Tortosa, Cindy Monnet

Les données sur la taille des domaines vitaux et l’activité spatio-temporelle des petits vertébrés sont souvent lacunaires. En effet, les animaux de petite taille sont difficiles à marquer individuellement et à suivre sur des périodes suffisamment longues pour recueillir des informations fiables. …

Spatial pattern and shelter distribution of the ocellated lizard (Timon lepidus) in two distinct Mediterranean habitats

Julien Renet, Théo Dokhelar, Félix Thirion, Laurent Tatin et autres

Abstract The knowledge of a species’ spatial ecology is essential for its conservation as it helps to implement targeted protection measures to suitable habitats. In 2011 and 2013, two French populations of ocellated lizards Timon lepidus were monitored through very high frequency …
