Abstract

ANGUIANO-CONSTANTE, Marco Antonio et al. Richness, geographic distribution and conservation of Lycianthes series Meizonodontae (Capsiceae, Solanaceae). Rev. Mex. Biodiv. [online]. 2018, vol.89, n.2, pp.516-529. ISSN 2007-8706.  https://doi.org/10.22201/ib.20078706e.2018.2.2340.

Lycianthes series Meizonodontae Bitter (Solanaceae) is monophyletic and includes 8 species and 2 varieties. The aim of this paper is to analyze the richness, distribution and conservation status of the series. Using geographic information systems (GIS), we evaluated the richness by latitude, longitude, elevation, political divisions, biogeographic provinces, vegetation types, a 83 × 83 km grid cell and species distribution models. Also, we estimated geographic distribution and conservation status for each taxon, according to criterion B2 of the IUCN. Lycianthes series Meizonodontae distributes from northeast of Mexico to central Costa Rica, with Mexico as its main center of diversification. The species richness concentrates in Central Mexico, where the Transmexican Volcanic Belt and the Balsas Basin converge. Based on their areas of occupancy (AOO), L. hintonii and L. starbuckii are considered as critically endangered (CR), while the rest of the species are least concern (LC). The potential distribution models suggest that the main richness of Lycianthes series Meizonodontae occurs in the Transmexican Volcanic Belt.
