Longitudinal vegetation turnover in an eastern Rift Valley riparian corridor
Abstract East African riparian corridors are biodiversity hot spots that occur in catchments degrading under deforestation and overgrazing. Quadrats and belt transects were employed to investigate plant succession along the River Gilgil, in the Kenyan Rift Valley. The study found that most species (total 365) were broadly distributed across the tropics,

Quantifying invasion degree by alien plants species in Reunion Island
This study aimed to quantify invasion degree by alien plants species in Reunion Island using three different sources of data : data from field survey, expert knowledge and model. Abstract The largest area of intact vegetation in the Mascarene’s archipelago is found on Reunion Island, but the remaining natural areas are under threats.

Abstract Endangered wildlife increasingly inhabits human‐dominated landscapes outside protected areas. Large‐bodied mammals require large spaces, and their ranging may be especially impacted by landscape modifications including farming, road development and urbanisation. We studied the Wagaisa community of chimpanzees (Pan troglodytes) in Uganda, which

Apport de la télédétection pour l’inventaire des renouées du Japon le long des cours d’eau : exemple d’application à la rivière Azergues [PDF]
De récents progrès réalisés en télédétection ont montré qu’il était possible d’identifier les renouées à partir de traitement d’images aériennes et de cartographier leur implantation de manière automatique ou semi-automatique. Cet article a pour objectif

Pour nombre de gestionnaires d'espaces naturels, la prise en compte des espèces exotiques envahissantes relève d'abord d'une question technique. Mais les approches en sciences humaines et sociales, qui s'intéressent tant aux perceptions dont elles sont l'

Data acquisition and management workflow implemented in the two analyzed case studies. In the Ramières Reserve, pioneer citizen scientists (i.e Citizen scientistA) have provided a large volume of visual data to allow accurate automatic identification by reserve managers and local citizen scientists (i.e Citizen scientistB), which yields reliable ...
