Flora fanerogámica de dos enclaves de sabana de la península de Yucatán, México

Abstract: En este trabajo se presenta el listado florístico, incluyendo las formas de vida de las angiospermas presentes en las sabanas de San Miguel Allende (Campeche) y de Chacho Lugo (Yucatán). Se registraron 142 especies pertenecientes a 96 géneros y 36 familias, siendo las plantas herbáceas las que tienen la forma de vida dominante. El valor Ij obtenido fue de 0.169, lo que demuestra las notables diferencias en la composición florística de cada una de las sabanas, las cuales comparten sólo 24 de las 142 especies re… Show more

“…The Belize and Tabasco savannahs have Am climate with higher rainfall than the other regions. In terms of physiography, the savannahs of the Yucatan Peninsula are small and established at the bottom of karstic valleys ( Várguez-Vázquez et al 2012 , Ortiz-Díaz et al 2014 ), while the Belize and Tabasco savannahs develop on extensive flatlands ( Puig 1972 , Penn et al 2004 , Bridgewater et al 2002 ). The savannahs on the Pacific Coast are distributed along peaks and the slopes of shale hills and this does not ocurr in other study regions ( Rzedowski 1978 , Pérez-García et al 2001 ).…”

“…In contrast, the archipelago effect may explain the low similarity values obtained at the adjacent sites of the Yucatan Peninsula. There, heterogeneity in physiographical and hydrological dynamics may lead to variation in the floristic composition ( Ortiz-Díaz et al 2014 ). The four Yucatan sites are categorised into two different geomorphological units; for instance, Miguel Allende is placed in an extensive karstic valley that favours rain overflow in the rainy season, while the other three savannahs are situated at the bottom of a tectonic valley forming part of a major structural valley system on a NW to SE orientation, such that they remain waterlogged during the rainy season ( Várguez-Vázquez et al 2012 , Ortiz-Díaz et al 2014 ).…”

“…Estas colecciones fueron realizadas por Cyrus Lundell en los años 1930. También hay proyectos importantes que no se limitan a una localidad particular, como el inventario de dunas y matorral costero en el estado de Yucatán (Torres et al 2010) y las sabanas de la Península de Yucatán (Ortíz-Díaz et al 2014).…”
