Species richness, endemism and conservation of Mexican gymnosperms

Evolutionary history of the flora of Mexico: Dry forests cradles and museums of endemism

“…Patterns of WE and WPE were similar, and particularly for endemism are consistent with earlier research on a number of taxonomic groups: (i) ferns, in which species richness was identified in the SE and in Chiapas, and weighted endemism in several areas in the Sierra Madre Oriental, in the Trans‐Mexican Volcanic Belt and Sierra Madre del Sur (Sanginés‐Franco et al, ); (ii) gymnosperms, for which areas of endemism coincided in the Sierra Madre Oriental and a small area in Oaxaca (Contreras‐Medina & Luna‐Vega, ); (iii) the monocot tribe Tigridieae (Iridaceae), for which endemism coincided in the eastern part of the Trans‐Mexican Volcanic Belt and the Sierra Madre Oriental, as well as in the Tehuacán Valley and in the Sierra Madre del Sur (Munguía‐Lino et al, ); (iv) oaks, Quercus spp., for which areas of endemism were identified in the Sierra Madre Occidental and in the Trans‐Mexican Volcanic Belt (Rodríguez‐Correa et al ); (v) the genus Bursera in which three areas of endemism were identified on the Central Mexican Pacific Coast, in the western Balsas River Basin and in the Tehuacán Valley (De‐Nova et al, ; Gámez et al, ); and (vi) cacti from the Chihuahuan Desert where high degrees of endemism were identified on the Mexican Plateau, as well as in the southern area of the Sierra Madre Oriental (Hernández & Gómez‐Hinostrosa, ). In addition, for one functional group, the monocot geophytes, significant areas of endemism were identified in the Trans‐Mexican Volcanic Belt, the Sierra Madre Oriental, and in the Tehuacán Valley, which also agrees with our results (Sosa & Loera, ).…”

“…). Earlier research has focused solely on endemism for certain plant groups such as the Tigridieae (Iridaceae), Bursera , oaks, cacti, monocot geophytes and ferns, and a number of studies have focused on patterns of species richness and endemic taxa in certain regions of Mexico (Dávila‐Aranda et al, ; Contreras‐Medina & Luna‐Vega, ; Riemann & Ezcurra, ; Hernández & Gómez‐Hinostrosa, ; De‐Nova et al, ; Gámez et al, ; Rodríguez‐Correa et al, ; Sanginés‐Franco et al, ; Munguía‐Lino et al, ; Sosa & Loera, ; De‐Nova et al, ). The majority of these studies identified the southern regions of the Sierra Madre Oriental and Sierra Madre Occidental mountain ranges, the Trans‐Mexican Volcanic Belt and the Tehuacán Valley as having high degrees of endemism.…”

Centres of plant endemism in China: places for survival or for speciation?

“…, 2002; Morawetz & Raedig, 2007) and much smaller (e.g. Mexico; Contreras‐Medina & Luna‐Vega, 2007) territories, but is too coarse to reveal patterns of endemism at the regional scale (e.g. to detect finer‐scale variations within major centres of endemism).…”

Conservation biogeography of red oaks (Quercus, sectionLobatae) in Mexico and Central America

“…In total, we had a database composed of 70 species of red oaks for Mexico and 17 species for Central America (Appendix S1, see Supplemental Data with the online version of this article). In addition, taxonomic treatments, monographs, and floristic studies were reviewed for distributional data (Muller, 1942, 1951; Martínez, 1951, 1953, 1954, 1959, 1965, 1966, 1974; Standley and Steyermark, 1952; McVaugh, 1974; Burger, 1977; Espinosa, 1979; Valdez and Aguilar, 1983; González‐Villarreal, 1986, 2003a, 2003b; Bello and Labat, 1987; de la Cerda, 1989; Spellenberg, 1992; Vázquez, 1992, 2000, 2006; Nixon and Muller, 1993; Valencia, 1995, 2004, 2005, 2007; Valencia and Jiménez, 1995; Spellenberg and Bacon, 1996; Romero et al, 2000a, 2000b, 2002; Breedlove, 2001; Encina and Villarreal, 2002; Valencia and Cartujano, 2002; Valencia et al, 2002; Valencia and Lozada, 2003; Santacruz and Espejel, 2004; Valencia and Nixon, 2004; Vázquez et al, 2004; Romero, 2006). With this information, a database including 13502 georeferenced records was constructed.…”
