“…El árbol de decisión mostró que la clasificación de las Pitayeras no está determinada necesariamente por las especies más dominantes o las más raras, aunque la mayoría de las especies que clasifican a las Pitayeras son comunes en los tres sistemas. Al respecto, es necesario considerar que la composición florística se relaciona con factores abióticos como el relieve, la topografía, la exposición, la altitud, el clima, el grupo de suelo y sus propiedades edáficas (Maia et al, 2020;Rodrigues et al, 2019;Gallardo-Cruz et al, 2009;Borchert, 1994). También se reconocen otros factores bióticos como la composición de la comunidad microbiana, las interacciones ecológicas y el manejo antrópico (Gavito et al, 2018;Flores y Bautista, 2012).…”

Background. Pitayeras are traditional agroforestry harvesting systems that have been poorly studied but can harbor a diversity of trees and shrubs as in tropical dry forest (TDF). Objective. We described the diversity of woody communities in Pitayeras of the Sierra de Huautla to identify their importance in the conservation of TDF species. Methodology. 150 plots with a defined area (10 x 10 m) divided into three Pitayeras (Plain, Hillside, and Orchard) were sampled. All individuals with a diameter ≥ 1 cm were quantified, and all species were identified. The alpha (H ', 0D, 1D, 2D) and the beta (Bray-Curtis) diversity were estimated. A tree classification was performed to classify the plant communities of the Pirayeras. Results. 57 species and 22 families were identified, which Fabaceae, Burseraceae, and Cactaceae were the most diverse. The most dominant species were Euphorbia schlechtendalii, Stenocereus stellatus and Mimosa polyantha. La Huerta was the most diverse Pitayera, while the Plain had the least diversity. The Plain and Orchard were the most similar Pitayeras. Implications. The diversity of trees and shrubs of the Pitayeras might be associated with particular edaphic, climatological and management conditions; however, these socio-ecological elements were not monitored. Conclusions. The Pitayeras harbor a diversity of trees and shrubs similar to the DTF of the Sierra de Huautla Biosphere Reserve and other parts of Mexico.

“…Esta estacionalidad supone la aparición de adaptaciones especiales de las plantas como respuesta al déficit hídrico, lo que significa altas tasas de endemismo y diversidad beta (DRYFLOR et al, 20 16;Pizano et al, 2014). La mayoría de los bs-T son estructuralmente menos complejos que los bosques húmedos tropicales, presentando menores valores de altura, área basal, biomasa y riqueza de especies; esto puede deberse a factores como el estado de conservación de los bosques, el clima y el tipo de suelo (Maia et al, 2020;Murphy y Lugo, 1986), y a la presencia de un sotobosque con mayor densidad de arbustos y abundancia de lianas (Gentry, 1995). En cuanto a su composición, el bs-T se caracteriza por la dominancia general de Fabaceae en el estrato arbóreo y de Bignoniaceae para las lianas (Gentry, 1995;Murphy y Lugo, 1986).…”

El bosque seco tropical del Jardín Botánico de Cartagena es uno de los pocos remanentes protegidos cerca de esta ciudad. Su estado de conservación y la abundancia de nacimientos de agua en la zona lo hacen único entre los remanentes de este ecosistema en el Caribe colombiano. En este contexto, el objetivo del presente estudio fue evaluar la estructura, composición, diversidad funcional y filogenética de la comunidad vegetal del área mediante una parcela permanente. Para ello se registraron 2023 tallos de 62 especies y la familia con mayor Índice de Valor de Importancia (IVI) fue Moraceae. La biomasa aérea total fue de 61.8 t.ha-1. Se encontraron dos tipos funcionales de plantas: uno adaptado al sotobosque y otro al dosel, y un bajo agrupamiento filogenético. Se concluyó que el bosque se encuentra en un estado de sucesión secundario intermedio a tardío y que la alta disponibilidad de agua en la zona, además de su ubicación aislada, han sido factores determinantes para su vegetación.

In the by‐tree method, a tree is sampled when its equivalent diameter (commonly the quadratic diameter) meets the minimum diameter threshold, meaning that all stems are included in the sampling rather than individual ones that meet the threshold (Figure 1).…”

“…The wide range of minimum size thresholds is motivated by differences in vegetation structural attributes, such as the tree size (diameter and height), growth rhythm, age structure and resprouting patterns (Moro & Martins, 2011). Generally, in semideciduous and deciduous tropical forests that are strongly associated with seasonal climates and water deficit, smaller trees and lower growth rates are prevalent in comparison to rainforests (Maia et al., 2020; Neves et al., 2017; Pennington et al., 2009). Within dry forests, a given vegetation size stratum may encompass trees of different successional stages when compared to the same stratum in rainforests (Moro & Martins, 2011).…”

1. Large-scale data compilation is increasing steadily in tropical forest research, but the lack of standardized methods for data collection limits drawing inference from large datasets and cross-biome analyses. Different inclusion methods and minimum tree diameter threshold are among these varying factors. To tackle this issue, we evaluated how different approaches for tree sampling affects our understanding of diversity and functioning in different tropical vegetation types.2. We used a unique dataset of 44 inventory plots (43.54 ha) encompassing an aridity gradient: evergreen moist forests, semideciduous and deciduous tropical forests.Data were collected using the by-tree inclusion method, in which, all stems are measured if the equivalent diameter of the tree reaches the minimum threshold.We simulated the impact of adopting different inclusion methods (by-stem and by-tree) and different minimum diameter thresholds on the estimation of number of trees and stems, biomass and species richness. We used linear and nonlinear mixed models to investigate the effect of minimum diameter threshold and inclusion method on our different response variables. We also evaluated species chance to be sampled under different minimum inclusion criteria.3. Inclusion method and minimum diameter threshold mainly affect the estimation of number of trees and stems and species richness, especially in deciduous and semideciduous forests, where resprouting is a prevalent strategy. In these forests, many trees that have several stems do not reach the minimum size individually when adopting the by-stem method, yet they do reach the minimum size threshold when all stems are considered together. For these environments under water stress, our analysis showed that using large minimum sizes, such as the 10 cm typically used in rainforests, implies large sampling losses, especially when used jointly with the by-stem inclusion method.4. The by-tree inclusion method represents an alternative approach that offers a more reliable sampling in different vegetation types, particularly in those habitats where resprouting is a widely encountered strategy along all age classes. 2018 | Methods in Ecology and Evoluঞon de SOUZA et Al.
