“…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.

“…Para la diversidad verdadera muchos de los trabajos citados aquí no tienen este resultado, por lo cual con base en la riqueza de especies obtenida con el índice de Shannon-Wiener y la formula exp (H´) se obtuvo esta misma. Para nuestro trabajo, se tiene que el transecto número seis es el más diverso de los siete transectos establecidos dando un valor 4.7114, pero es bajo al compararlo con los tres sitios de muestreo que tiene Ticante-Montero (2015), pues el valor más alto para el sitio uno está representado con 20.2873, de la misma forma con Zamora-Crescencio et al, (2017); Basáñez et al,(2008); Veiga et al, (2015) que poseen áreas más diversas que este trabajo, por otro lado Cruz-Vidal (2013) tiene valores de 3.7359 y 3.1455 para las parcelas 7 y 8 las cuales se comparan con el transecto uno de este muestreo.…”

Se caracterizó la composición y estructura arbórea del sitio Solteros de Juan Rosas, Papantla, Ver. Para ello se establecieron siete transectos de 50m x 20m, distribuidos al azar, utilizando la metodología de Gentry (1982) contando individuos con un DAP mayor o igual a dos punto cinco centímetros, se registraron un total de 87 individuos, con una riqueza de 11 especies, distribuidas en siete familias y 11 géneros. La diversidad alfa (α) estimada mediante el índice de Shannon Wiener dio un valor de H= 1.872, indicando la baja diversidad presente en este ecosistema. La diversidad verdadera para el transecto seis fue mayor comparada con los otros transectos, con un valor de 3.6840, siendo el más diverso.

“…Los resultados de riqueza y diversidad obtenidos son inferiores a los reportados para BTA's de la región de estudio (Zamora-Crescencio et al, 2008;Gutiérrez-Báez et al, 2012). Por el contrario, son similares a los de otros bosques temporalmente inundables del sureste de México (Olmsted & Durán, 1986;Díaz-Gallegos et al, 2002;Hernández-Ramírez & García-Méndez, 2015;Maldonado-Sánchez et al, 2016).…”

“…El clima predominantes es del tipo Aw1 (i ') g, cálido y húmedo con lluvias en verano, la temperatura media anual es de 26.3 °C, con precipitación media anual de 1 122 mm (INEGI, 2009). El tipo de vegetación dominante es el bosque tropical subcaducifolio, y en menor proporción se desarrollan sabanas y bosques temporalmente inundables (ZamoraCrescencio, García-Gil, Flores, & Ortiz, 2008;Gutiérrez-Báez, Ortiz-Díaz, Flores-Guido & Zamora-Crescencio, 2012).…”

Diversity, structure and floristic affinities of a temporarily flooded forest of the Yucatan Peninsula. Temporarily flooded forests (TFF's) are among the most endangered tree communities in Southeast Mexico and in a contradictory way among the least known in terms of their diversity. Therefore, the aim of this study was to characterize the richness, diversity (Shannon-Wiener) and dominance (relative importance value; RIV) of a TFF of the Yucatan Peninsula, and evaluate its floristic affinities with other TFF's and upland forests (UF's) of Southeast Mexico. A sampling method based on 10 quadrants of 10 x 20 m (2 000 m 2 ) was used to record all woody individuals with diameter ≥ 1 cm and height ≥ 1.5 m. A floristic similarity analysis was used including 192 genera of woody plants belonging to TFF's and UF's of the Yucatan and Tabasco TFF's. A Mantel correlation test was performed to determine if the geographic distance has effect on the floristic similarities between TFF's and UF´s of the Yucatan peninsula. The TFF under study was characterized with a low level of diversity (2.79) and species richness (56), and a high dominance level (52.3 % of RIV in five species). Dominant species such as Haematoxylum campechianum, Dalbergia glabra, Cameraria latifolia, Byrsonima crassifolia, Crescentia cujete and Terminalia buceras showed a floristic neotropical affinity typical of floodable habitats. The structure of the community was characterized by an inverted "J" pattern for the distribution of individuals in the diametric and height classes. The high density of woody lianas, mainly of Dalbergia glabra (22 % of the recorded individuals) suggested an optimal state of conservation of the studied area. The floristic similarity analysis revealed that most of TFF's in Yucatan Peninsula were grouped with high similarity (55 %) independently of the adjacent UF's; however, TFF´s resulted similar among them (36 % similarity) when compared with TFF's from other regions (16 % similarity). According to the Mantel test, the similarity between sites is not influenced by its geographical proximity (r = -0.098, p>0.05). This emphasizes the need to generate conservation strategies for the TFF's of the Yucatan peninsula independently from other regions of Southeast Mexico. Our results suggest that the TFF of the studied region has a similar diversity from other TFF's in Southeast Mexico, a different floristic composition compared with adjacent UF's and a structure with an optimal conservation status, characteristics that indicate their importance for the regional flora conservation. Further ecological studies are needed to build a solid foundation for management and conservation for the TFF's. Rev. Biol. Trop. 65 (3): 868-880. Epub 2017 September 01.
