dc.description.abstract | Stylosanthes is a mainly Neotropical genus comprising ca. 25 species with Venezuela hosting high species richness. Despite of the economic importance of some species as forage legumes, the biogeography of Stylosanthes in Venezuela has hitherto been poorly studied. Information of herbarium specimens and germplasm accessions was collated in order to assess distribution, range size, geographic species richness and rarity in the country. Stylosanthes guianensis has the widest geographical distribution and the largest range size. The highest species richness occurs in the eastern plains (“Llanos”) (7-10° N, 62-65° W). The endemic S. sericeiceps and S. venezuelensis fall within the rarest category. This study contributes to better understand the pattern of biogeographical variation of Venezuelan Stylosanthes species, and can help to design conservation strategies. | en_US |
dc.description.abstract | Stylosanthes es un género principalmente neotropical, encontrándose en Venezuela una considerable riqueza específica. A pesar de la importancia económica de algunas especies como leguminosas forrajeras, la biogeografía de Stylosanthes en Venezuela ha sido poco estudiada. Información de herbarios y bancos de germoplasma fue recopilada para evaluar distribución, tamaño del área biogeográfica, riqueza específica y rareza. Stylosanthes guianensis tiene la distribución geográfica más amplia y ocupa la mayor área biogeográfica. La mayor riqueza específica se encuentra en los Llanos (7-10° N, 62-65° O). Dos especies endémicas, S. sericeiceps y S. venezuelensis, pertenecen a la categoría más rara. Este estudio contribuye a comprender los patrones de variación biogeográfica de las especies venezolanas de Stylosanthes y podrá asistir en diseñar estrategias de conservación. | en_US |
dc.description.sponsorship | ACKNOWLEDGEMENTS: We thank the collection managers and curators of the herbaria listed in the methods section for granting access to their herbarium collections. The authors also thank the Genetic Resources Program of CIAT for providing the passport data of their Venezuelan collections. We are also indebted to the Eiselen Foundation, Ulm, Germany; the National Fund for Science, Technology and Innovation (FONACIT, its Spanish acronym), Caracas, Venezuela; the Foundation Gran Mariscal de Ayacucho (Fundayacucho, its Spanish acronym), Caracas, Venezuela, and the German Academic Exchange Service (DAAD, its German acronym), Bonn, Germany, for their financial support of this project. Last but not least, the authors would like to thank the three reviewers and the editor, who made important suggestions for improving the final manuscript. | en_US |
