The Calakmul region, at the center of the Yucatan peninsula, contains the largest forested area of the Mexican tropics. Our objective is to provide the classification, description and spatial distribution of the plant communities of Calakmul region. In spite of the relatively lack of topographic features there is large spatial heterogeneity in the vegetation. Five plant associations are underlined because of their regional, national and world relevance: guayacán forest (Guaiacum sanctum), jobillo forest (Astronium graveolens), low deciduous forest, tall forest and mixed seasonally flooded forest. We discuss the main factors influencing the vegetation, including rainfall gradients, soil development, natural disturbances and anthropogenic factors. This study underscores the importance of using vegetation classification with enough detail to assess the representation and effectiveness of natural protected areas.

Introduction: The Lignum-vitae (Guaiacum sanctum; Zygophyllaceae) of Mesoamerica and the Greater Antilles, is threatened over much of its range. We evaluated whether a G. sanctum population in the Palo Verde National Park of Costa Rica is viable in the long term. Methods: Using two demographic studies, one in 1997 and the other in 2017, we estimated survival and fecundity rates for each tree age class, population growth rate (lambda), and vital rates elasticities, and we used a density-independent deterministic population model to project the long-term trend of that population. Results: The estimated vital rates during the last 20 years suggested that this population is rapidly decreasing. Although some age classes increased in abundance, seedlings are rare and the plants that recruited in 1997 have not yet reached reproductive maturity. Our results suggest that the current abundance of G. sanctum within the national park may not be a good indicator of its long-term conservation status, and from our population viability analysis, we estimated that the population we studied would decrease to less than 1 % of its current size within the next 200 years. Conclusions: Landscape-scale ecosystem deterioration affecting the greater PVNP region, such as loss of seed dispersers and suppression of disturbances, may offset the passive protection of G. sanctum within park boundaries. Relying on the overall strict protection afforded by the location of the population within the Palo Verde National Park may not be sufficient to conserve this population of G. sanctum. We recommend that more proactive experimental protection and/or restoration measures, possibly including disturbance treatments, be implemented within a research program.

Guaiacum Sanctum

In Costa Rica Albizia guachapele, Cedrela odorata, Platymiscium pinnatum and Guaiacum sanctum are important plant species in both economic and ecological terms and their wood is precious and reported to be highly resistant material. This research has evaluated the in vitro micropropagation as a technology focused to conserve these species. Findings include percentage of germination of seeds and contamination, induction of buds, rooting and growth of micro-cuttings of these four species. Key words:  In vitro, Propagation, Albizia guachapele, Cedrela odorata, Platymiscium pinnatum, Guaiacum sanctum D.O.I. 10.3329/ptcb.v18i2.3397 Plant Tissue Cult. & Biotech. 18(2): 151-156, 2008 (December)
