Aims Addressing plant responses to water stress is critical to understand the structure of plant communities in water-limited environments and to forecast their resilience to future changes in *** a semiarid agroforestry system in the Sahelian savannah of Leona(Senegal),we selected nine common tree species and explored their stress-resistance *** species represent a variety of life forms and are of high regional socio-economic *** hypothesized that different species would show different suites of traits to cope with water stress and expected to identify functional groups differing in strategies to withstand water *** Along a dry and a wet season,we monitored four traits reflecting above-and below-ground strategies of resource acquisition such as predawn leaf water potential(ψpd),specific leaf area(SLA),leaf thickness and leaf area index(LAI).We also measured two mor-phological traits:trunk diameter and tree *** andψpd were measured six times during the dry and rainy seasons,and the other traits were measured *** Findings We identified two functional classes subdivided into two func-tional groups of each *** first class included deciduous and semi-deciduous species that generally had large SLA,low leaf thickness and small-to-intermediate inter-seasonal varia-tions inψ*** second class included evergreen species of two functional groups that differ in SLA,leaf thickness and the mag-nitude of inter-seasonal variations ofψpd throughout the *** four functional groups identified in this study represent plant strategies differing in their response to changing environmental conditions.
