摘要

Wild palms contribute significantly to food security and local economy in tropical areas, and particularly in sub-Saharan Africa. In light of this importance, eight palm species were explored [Borassus aethiopum (L.) Mart, Eremospatha macrocarpa (G. Mann et H. Wendl.) H. Wendl., Laccosperma opacum (G. Mann et H. Wendl.) Drude, Hyphaene thebaica (L.) Mart, Phoenix reclinata Jacq., Raphia hookeri G. Mann et H. Wendl., R. sudanica A. Chev., and R. vinifera P. Beauv.] as targets for conservation, domestication, and cultivation in Benin. Cultivation potential was evaluated in a coarse-resolution, first-pass effort using ecological niche models to relate known occurrences of each species to vegetation indices (VEG), gross primary productivity (GPP), and soil characteristics (SOIL), and model outputs were related to human distribution and land-use patterns. Results showed that wild palms responded differentially to different suites of environmental factors: some species showed best model performance with VEG + GPP + SOIL, others with GPP + SOIL or VEG + GPP, or with a single factor. Two species had broad potential distributions across the country; others had potential areas in the north (2 species) or the south (4 species). Raphia hookeri and R. vinifera showed greatest overlap in terms of ecology and distribution, whereas L. opacum and R. sudanica had the lowest similarity. These models constitute initial steps toward a sustainable scheme for planning exploration of the possibility of cultivation of these species.

Wendl。）博德，Hypheene Thebaica（L.）Mart，Phoenix Reclinata Jacq。，Raphia Hookeri G. Mann等H. Wendl。，R. Sudanica A. Chev。和R.Vinifera P. Beauv。]作为保护，驯化和和贝宁栽培。采用生态利基模型以粗辨率为一级促进培养的培养潜力，以将所知的每种物种与植被指数（蔬菜）相关，初级生产率（GPP）和土壤特征（土壤）以及模型产出的促进与人类分配和土地使用模式相关。结果表明，野生棕榈树差异地对环境因素的不同套件进行了差异：一些物种与veg + GPP +土壤，其他物种具有GPP +土壤或Veg + GPP的最佳模型性能，或单一因素。两种物种在全国范围内具有广泛的潜在分布;其他人在北部（2种）或南部（4种）有潜在的地区。 Raphia Hookeri和R.Vinifera在生态和分布方面表现出最大的重叠，而L. Opacum和R. Sudanica具有最低的相似性。这些模型构成了朝着计划探索这些物种培养的可能性的可持续计划的初步措施。
