Diversity, plasticity and asynchrony of senescence in the Collembola Folsomia candida

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 […]

Müllerian mimicry among bees and wasps: a review of current knowledge and future avenues of research

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.

A stressful life in the city affects birds’ genes

Great tits living in cities are genetically different from great tits in the countryside. This is what researchers have found in a unique study, where they examined populations of great tits in nine large European cities.

The researchers compared the city bird genes with the genes of their relatives in the countryside. It did not matter if the great tits lived in Milan, Malmö or Madrid: in order to handle an environment created by humans, the birds evolved in a similar way.
