Persistence of soil organic carbon caused by functional complexity

Soil carbon persistence can be understood through the lens of decomposers as a result of functional complexity derived from the interplay between spatial and temporal variation of molecular diversity and composition. For example, co-location alone can determine whether a molecule is decomposed, with rapid changes in moisture leading to transport of organic matter and constraining the fitness of the microbial community, while greater molecular diversity may increase the metabolic demand of, and thus potentially limit, decomposition.

Environmental pulse disturbances disproportionately affect large body size species

Smaller organisms are typically more abundant than larger ones, which is a fundamental characteristic of ecological communities. How environmental pulse disturbances affect these « abundance pyramids » remains poorly understood. In a study recently published in Ecology Letters, researchers from iEES Paris and the University of Zürich showed that disturbances which are not size-selective still […]

Making better use of the third dimension of agricultural land to sustainably intensify agricultural production

In this prospective article, an international consortium coordinated by researchers from the University of Copenhagen examines the prospects for using the “third dimension” of agricultural land, i.e. the possibility, without resorting to new land, of increasing the volume of soil exploited by the root system of crops, thereby increasing the resource base available for agricultural production while minimizing the undesirable externalities frequently associated with current agroecosystems.

City and forest ants are surprisingly similar genetically

City life could lead to differential evolution between urban and forest populations. Aurelie Khimoun and her collaborators showed, in their article published in Biology Letters, that urban populations of the tiny acorn ant are surprisingly not genetically differentiated from forest populations, suggesting expansion and lack of isolation. However, some genes display traces of selection that point towards an adaptation to the urban environment.

Obama chez moi! The invasion of metropolitan France by the land planarian Obama nungara(Platyhelminthes, Geoplanidae)

Obama nungara is a species of land flatworm originating from South America; the species was recently described and distinguished from a similar species, Obama marmorata. Obama nungara has invaded several countries of Europe, but the extent of the invasion has not been thoroughly mapped.

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 […]
