Taxonomic revision of Zamia in Mega-Mexico
The genus Zamia is revised for Mega-Mexico, with 22 species recognized and described, and a contribution that provides the foundation for a future monograph for Zamia in the Neotropics is presented.
Cryptic diversity, sympatry, and other integrative taxonomy scenarios in the Mexican Ceratozamia miqueliana complex (Zamiaceae)
The present work contributes to establish a robust platform for subsequent systematic assessments of Mexican cycad diversity, which could include new hypotheses on the evolutionary processes involved in their current biogeographic distribution, ecological relationships, and other life-history aspects, in turn useful for conservation biology concerns.
Diversity and genetic structure of three species of Dioon Lindl. (Zamiaceae, Cycadales) from the Pacific seaboard of Mexico
Comparison of the inferred genetic structure based on F-statistics for the three species indicated differences along the north-south Pacific seaboard axis and a phenogram representing Nei's genetic distances among populations displayed three major groups, each one corresponding to each of the studied species.
Allozyme diversity levels in two congeneric Dioon spp. (Zamiaceae, Cycadales) with contrasting rarities
The comparison of population genetic structure information with historical and geographical aspects of the populations suggests that the rarity of D. caputoi might be due to relatively recent local ecological factors, and genetic structure does not differ between the two species despite their contrasting geographic distributions.
Taxonomic review of Ceratozamia (Zamiaceae) in the Sierra Madre Oriental, Mexico
A comprehensive taxonomic revision with history of nomenclature and the morphology, relationships, distribution and use of Neotropical species of Ceratozamia for the Sierra Madre Oriental in Mexico is presented.
Integrative taxonomy of Mexican cycads: biogeography, morphology and DNA barcoding corroborate a new sympatric species in Ceratozamia (Zamiaceae)
A new species, from the montane region of Los Tuxtlas (state of Veracruz, Mexico), Ceratozamia subroseophylla , is proposed in accordance with the integrative taxonomy framework and through
A novelty in Ceratozamia (Zamiaceae, Cycadales) from the Sierra Madre del Sur, Mexico: biogeographic and morphological patterns, DNA barcoding and phenology
This work describes a new species from the Pacific region of Mexico in Guerrero state, which represents the most northwestern Mexico distribution for Ceratozamia, and introduces phenology as additional information for species circumscription.
A character‐based approach in the Mexican cycads supports diverse multigene combinations for DNA barcoding
None of the three combinations of potential DNA barcoding loci found to be optimal with a character‐based approach in the Mexican cycads coincides with the ‘core barcode’ of chloroplast markers (matK’+ rbcL) recently proposed for universal use in the plant kingdom.
Phylogeography and demographic history of Zamia paucijuga Wieland (Zamiaceae), a cycad species from the Mexican Pacific slope
The results imply that the average genetic diversity in Z. paucijuga is lower in comparison with other cycad species, but relatively higher than the diversity found in conifers.
Reciprocal illumination of morphological characters upon a molecular hypothesis supports the proposal of a new species of cycad from Mexico
The proposal of D. stevensonii rests on the reevaluation of overlooked differences in morphological character states in herbarium material corresponding to populations previously identified as D. tomasellii, which also includes populations located in Durango, Nayarit and Jalisco.
