To extract any adaptive benefit, the circadian clock needs to be synchronized to the 24-h day-night cycles. We have investigated if it is a general property of the brain’s circadian clock to recognize social interactions as external time givers. Sociosexual interactions with the opposite sex are universal, prevalent even in the lives of solitary animals. […]

Flourishing recent comparative studies on senescence have revealed an uncovered diversity across the tree of life of the shapes of the age trajectories of mortality (actuarial senescence) and to a lesser extent of reproduction (reproductive senescence). Evolutionary theories have been called up to explain why some species suffer from positive senescence while others benefit from […]

Wind erosion is a major phenomenon in the Sahel, and can affect soil fertility. Studies of Sahelian aeolian erosion or erosivity are scarce and have been mainly focused on the Central Sahel. Since February 2020, the number of saltating particles and the horizontal flux of aeolian sediment were monitored in Bambey (Senegal) in combination with […]
Installing urine collection systems in sub-Saharan city regions would make those conurbations more sustainable. This was demonstrated by a study by four researchers from CIRAD, IRD, Boubakar Bâ University of Tillaberi (Niger) and Joseph Ki-Zerbo University, Ouagadougou (Burkina Faso), published on 3 May 2023 in the journal Regional Environmental Change.

A study in Biological Reviews led by researchers from the Institute of ecology and environmental sciences – Paris, the Institute of Systematics, Evolution, Biodiversity and the Center for Ecology and Conservation Sciences makes the synthesis of published knowledge on Mullerian mimicry in aculeate wasps and bees. It argues that aculeates may be one of the most diverse groups of mimetic organisms and that the diversity of their mimetic interactions is currently underexplored.
