Reproductive adaptations in Prosopis (Leguminosae, Mimosoideae).
Presents quantitative data from an original study in Arizona and Catamarca Province, Argentina, on phenology, production of flowers, fruits and seed, seed destruction by bruchid beetles, and seed germination tests (including some of seed taken from animal excrement), plus some additional qualitative observations (e.g. on seedling development), for the S. American species P. chilensis and P. flexuosa and the N. American P. velutina. The data on seed destruction and germination also include results for 13 other species of Prosopis. The results are discussed as illustrating aspects of the adaptive 'strategy' of reproduction in the species studied - a 'strategy' that is probably shared by other arborescent phreatophytes of semidesert regions.
