“…The floristic inventory shows that the Region of Palmito de Verde follows a pattern similar to others sites in Mexico, in relation to the more abundant families. The family Fabaceae usually is the most common in dry and semideciduous forest in the country (Lott et al 1987;Gentry 1995;Zamora-Crescencio et al 2008;Rocha-Loredo et al 2010;Gutiérrez-Báez et al 2011;Gutiérrez-Báez et al 2012;León-de la Luz et al 2012;Dzib-Castillo et al 2014;Méndez-Toribio et al 2014;Bravo-Bolaños et al 2016;Gutiérrez-Báez et al 2016;Gutiérrez-Báez et al 2017;Zamora-Crescencio et al 2017). In relation to Mangroves, this information only reinforces what has already been published by Blanco y-Correa Magallanes (2011).…”

Sinaloa is among the states of Mexico harboring the highest deforestation rates. Reforestation programs have been put up in south Sinaloa with species chosen for their high seedling rates, structural importance or strong restoration value. However, species criteria such as level of endemism as well as rarity appear to be underestimated. Eight sampling sites were randomly selected and a botanical survey was carried out at least every month from 2015 to 2017. In order to rank species over conservation stakes, a Floristic Originality Index method was elaborated using species level of endemism, rarity and conservation status. The floristic inventory enabled the identification of a set of 250 species with the Fabaceae being the most represented family with 51 species. Using the Floristic Originality Index, a subset of 51 species was selected as priority for conservation along with 23 other species all displaying characteristics of “framework” species. Features of reproduction and types of ideal soil conditions for reforestation are presented for each species. The method developed to determine floristic originality has proven a set of most vulnerable and rare species to select “priority” and “framework” tree species able to restore forests structure and biodiversity as well as ecosystem functions. This evaluation is made from a conservation biology point of view and appears to be well adapted for studies at a local scale.

“…The Balsas River basin is a large region in the Mexican tropics of complex orography (Ferrusqu ıa-Villafranca 1993), where seasonally dry forests occupy large areas along steep environmental gradients (Mart ınez-Cruz et al 2013;M endez-Toribio et al 2014). Despite their large extent, these forests are visibly affected by rural livestock production and the extraction of forest products (firewood and construction timber; CONANP 2006).…”

Questions What is the magnitude of the differences in environment and chronic human disturbance between contrasting slope aspects and topographic positions in a seasonally dry tropical forest? What is the effect of such topography‐related differences on composition, structure and diversity attributes of the tree community of this forest? Location Tziritzícuaro, Michoacán State, southern Mexico. Methods Vegetation was sampled in 36 100‐m2 plots evenly distributed among three topographic positions (lower, middle and upper parts of a slope) and two slope aspects (N‐ and S‐facing). Environment at these sites was described through modelling incoming solar radiation and in situ recording of temperature during 1 yr. Disturbance was visually assessed in the field to calculate a Chronic Disturbance Index. Vegetation structure and diversity were compared among the resulting combinations of slope and topographic position. PERMANOVA and CCA were used to examine the multivariate relationship among vegetation, topography and disturbance. Results Slope aspects and topographic positions differed in terms of annual mean temperature, potential energy income and evapotranspiration. Conversely, disturbance was not so clearly related to topography. Regarding vegetation structure, significant differences were only found for individual sizes and abundance; these values increased towards the upper portion of S‐facing slopes, but decreased with elevation in N‐facing slopes. Species diversity (S, Jacknife 1 and Fisherʼs α) was higher in S‐facing slopes and increased from lower to upper topographic positions. PERMANOVA showed that vegetation structure and diversity were influenced by topographic position (12.9%) and the interaction between soil moisture and chronic disturbance with slope aspect (8.2% and 8.3%, respectively). CCA showed that a modest proportion (21%) of variation in species composition is explained by the combination of environmental and disturbance variables. Conclusions Slope aspect and topographic position represent axes of environmental and disturbance differentiation. Although vegetation attributes respond to these ecological factors, they do not show homogeneous responses. Floristic composition is clearly linked to environmental heterogeneity, while structural attributes and α‐diversity appear to be more closely related to human disturbance and soil moisture, particularly on S‐facing slopes. Integrating environmental heterogeneity and human disturbance with topographic variability enhances our understanding of large variation in tree community attributes in seasonal dry tropical forests.

“…One of the quadrats with 50 monocot geophyte species corresponds to the Tehuacán Valley, which was established as a protected area because of its plant diversity and endemism (Méndez-Larios et al 2005). For the Balsas River Basin a high degree of diversity and endemism of woody species of Leguminosae, Bursera (Burseraceae) and Cordia (Boraginaceae) have been documented (Pineda-García et al 2007). Seasonally dry tropical forests in the Neotropics are a metacommunity of tropical forests that grow on fertile soils in areas with erratic precipitation regimes and with elevated endemisms (Pennington et al 2009).…”

Background: Geophytes, plants with underground perennating organs that lose their aerial organs annually, are able to survive in harsh habitats. This life form is common in the monocots that inhabit Mediterranean climates around the world. In Mexico only the northern area of Baja California has this type of climate. Hypothesis: In this study, we recorded the species and distribution of Mexican geophyte monocots to pinpoint diversity hotspots. Our hypothesis is that the highest diversity of geophytes will be found in biogeographic areas with complex topography and seasonal climate not only in the north of the Baja California Peninsula. Data description: Records of geophytes were taken from different sources, collections, taxonomic references and diversity databases. Geophyte locations were mapped in the context of biogeographic and protected areas. Climate preferences were estimated using bioclimatic variables and by a Principal Component Analysis we identified the most significant variables explaining distribution of geophytes. Results: The Mexican geophyte flora is composed of 476 species, approximately 10 % of the total diversity of monocots. Echeandia and Tigridia were the two most diverse genera. This flora is dominated by the taxa of Orchidaceae, Asparagaceae and Iridaceae, and ten small endemic genera were recorded. Geophyte diversity was highest in two biogeographic provinces: the Trans-Mexican Volcanic Belt and the Sierra Madre del Sur, in dry forests such as oak-pine, seasonally dry tropical forests and semi-arid shrubby vegetation. Three bioclimatic variables: temperature seasonality, annual precipitation and precipitation of the wettest quarter resulted significant for understanding distribution of geophytes. Conclusions: Areas sustaining a high diversity and endemism of geophytes are located in the Mesoamerican Biodiversity Hotspot, in unprotected and threatened areas. Our results suggest that geophytes are able to grow in different climates but in areas with marked temperature seasonality and variation of annual precipitation. Keywords: Balsas River Basin, Chiapas Depression, Echeandia, endemism, Tigridia, Tehuacán Valley, Trans-Mexican Volcanic Belt Patrones de diversidad de geofitas monocotiledóneas en México ResumenAntecedentes: Las geofitas son plantas que poseen órganos de perennación subterráneos, las cuales pierden sus hojas anualmente y son capaces de sobrevivir en ecosistemas inhóspitos. Esta forma de vida es común en las monocotiledóneas que habitan en áreas con clima Mediterráneo en todo el mundo. En México únicamente el área norte de Baja California tiene este tipo de clima. Hipótesis: En este estudio se registra la diversidad y endemismo de las geofitas monocotiledóneas en México para identificar áreas con alta diversidad. Nuestra hipótesis plantea que la más alta diversidad de geofitas monocotiledóneas se encontrará en provincias biogeográficas con topografía compleja y variados tipos de climas y no solamente en Baja California.
