In the city, the seasonal patterns of activity of insect pollinators could be disturbed by the urban microclimate as well as by the presence of ornamental flora. To study this phenomenon, Vincent Zaninotto and his collaborators monitored the activity of insect pollinators in Paris and in the natural environment, from late winter to autumn. In […]

City and forest ants are surprisingly similar genetically

City life could lead to differential evolution between urban and forest populations.

However, some genes display traces of selection that point towards an adaptation to the urban environment.

Urban Ecosystems: A dialog between Scientists and Paris City Managers

For more than 10 years, the City of Paris and the Institute of Ecology and Environmental Sciences of Paris have been collaborating on various issues of urban ecology. From these multiform collaborations at the interface between fundamental research and concrete techniques for the management of urban environments, several advances have been made on both scientific […]
