Prioritising natural heritage: Evaluating distribution, threats, and conservation needs of species recovery targets in Vietnam Open
Our study addresses the urgent need to identify and prioritise threatened species in Vietnam for conservation and recovery. With a focus on Vulnerable, Endangered, and Critically Endangered species with high levels of endemicity (> 50% of …

Utilizing thermal imaging drones to investigate sleeping site selection in an arboreal primate Open
Sleeping site selection is essential for understanding primate behavioral ecology and survival. Identifying where species sleep helps determine priority areas and critical resources for targeted conservation efforts. However, observing sle…

A model for the noninvasive, habitat-inclusive estimation of upper limit abundance for synanthropes, exemplified by <i>M. fascicularis</i> Open
Accurately estimating population sizes for free-ranging animals through noninvasive methods, such as camera trap images, remains particularly limited by small datasets. To overcome this, we developed a flexible model for estimating upper l…

Ecological functions drive variation in external eye appearance across macaques Open
A growing number of studies have investigated the evolutionary drivers of external eye appearance in primates, but conclusive evidence is lacking. The literature has distinguished between two types of functions. Communicative functions, su…

Montane Grassland Resources Drive Gorilla (Gorilla Gorilla) Nesting Behaviours in the Ebo Forest, Littoral Region, Cameroon Open
Great apes show strong attachment to their nesting sites which provides them with substantial survival elements. Their nesting behaviors are influenced by geographical and ecological variables including habitat type, slope, elevation gradi…

CoFee-L: A Model of Animal Displacement in Large Groups Combining Cohesion Maintenance, Feeding Area Search and Transient Leadership Open
In the tropics, the conservation of tree species is closely linked to that of animals, as a large proportion of trees are zoochoric and therefore rely on the movement of animals to disperse their seeds in order to increase the chances of t…

CoFee-L: A model of animal displacement in large groups combining Cohesion maintenance, Feeding area search and transient Leadership. Open
BackgroundIn the current context of climate change and intensive anthropization of natural environments, the preservation of ecosystems is a matter of great importance. In the tropics, the conservation of tree species is closely linked to …

Seed Shadows of Northern Pigtailed Macaques within a Degraded Forest Fragment, Thailand Open
Research Highlights: Frugivores able to disperse large seeds over large distances are indispensable for seedling recruitment, colonization and regeneration of tropical forests. Understanding their effectiveness as seed dispersal agents in …

Cultural flies: Conformist social learning in fruitflies predicts long-lasting mate-choice traditions Open
Trendsetting flies Though once believed to be confined to humans, culture has now been demonstrated in many different animal species, from whales to parrots. Most such animals have high levels of cognition, but the basics of transmission a…
