Catálogo de las plantas vasculares de Río Muni (Guinea Ecuatorial): análisis florístico, diversidad, endemicidad y estado de amenaza

Abstract

Se presenta un catálogo actualizado de las plantas vasculares de la región continental de Guinea Ecuatorial (Río Muni). El catálogo es fruto de la compilación de especímenes de herbario (6,850), registros de especies de la literatura botánica (7,985) y bases de datos en línea (10,109 registros de GBIF y 8,897 de RAINBIO). Se elaboró una base de datos de 23,517 registros georreferenciados realizando la actualización nomenclatural y estandarización de los nombres de localidades de todas estas fuentes. El catálogo comprende 2707 taxones (2598 especies, 81 subespecies y 28 variedades) incluidos en 1,020 géneros y 178 familias. El 90.6% de los taxones se consideran nativos, el 1.17% introducidos y el 5.96% naturalizados. Las 10 familias más diversas son Rubiaceae (294 especies), Fabaceae (290), Orchidaceae (168), Poaceae (105), Euphorbiaceae (87), Apocynaceae (85), Cyperaceae (79), Annonaceae (68), Acanthaceae (65) y Melastomataceae (61), que comprenden el 49.22% de las especies de Río Muni. Solo 11 especies pueden considerarse endémicas de Río Muni; este bajo número refleja la ausencia de barreras naturales en el territorio. El número de taxones amenazados (VU, EN y CR) es de 134 (5.02% del total evaluado) de los cuales 43 se encuentran en riesgo de extinción, al estar dentro de las categorías de En Peligro o En Peligro Crítico. Cinco especies restringidas al Golfo de Guinea se consideran amenazadas: tres En Peligro (Grossera angustifolia, Polyscias aequatoguineensis y Rhipidoglossum montealenense), y dos En Peligro Crítico (Asplenium carvalhoanum y Macropodiella uoroensis), por lo que deberían considerarse prioritarias en los planes de gestión y conservación.
