“…Abiotic variables related to elevation (such as temperature, precipitation, and productivity) have a direct influence on species diversity in Neotropics (Rahbek, 1995). Especially in our study area, it has been shown that there is a different effect of this variable on different plant groups (Bautista-Bello et al, 2019; Monge-González et al, 2020). Mainly, this pattern could be explained by the interactive effect of temperature and water availability known as the water-energy dynamics hypothesis (O’Brien, 1998).…”

Background and Research One noteworthy element found throughout the tropical anthropogenic mosaic is the live fence, which is established within agricultural matrices and its structure within the landscape retains ecological processes, but few are recognized as elements of biological and cultural conservation. Methods In this study, we have researched plant diversity and anthropic management of live fences in five sites surrounded by contrasting vegetation references: Tropical evergreen forest; tropical deciduous forest; cloud forest; and pine–oak and pine forests. We recorded the type of management by interviews with peasants. We established thirty 2 × 50 m transects within each site and sampled two strata: trees and saplings. Also, we documented seed dispersal mechanism, life form, local use, and origin of each species. Importance Value Index and diversity metrics were estimated for each site. Results 253 plant species were registered (181 genera/74 families). While fences associated with the tropical deciduous forest showed the greatest species richness (109 species), the pine forest fences showed the lowest richness (21 species). Zoochory was the main type of seed dispersal mechanism. Conclusions Independent to the site and the altitude, the configuration of living fences is structured by three processes: the selection of the initial trees, the availability of the arrival of zoochory species, and the tolerance of the owners for the plant species. Implications for Conservation Based on our results, live fences can be considered important tools for landscape management in Mexico.

“…This pattern for herbs may be shaped by human disturbances and length of the growing season, which may have a more pronounced influence on the persistence and growth of short-living (annual and biennial) herbs than on that of perennial woody plants (Gómez-Díaz et al, 2017;Bhatta et al, 2021). The slightly increasing contribution of shrubs to total richness along the elevation gradient may be shaped by the interaction among PET, anthropogenic disturbance, and temperature change along the elevation gradient, as reported in Veracruz, Mexico (Bautista-Bello et al, 2019) and northern China (Zhang et al, 2016).…”

“…There are also examples of a uniform pattern of tree diversity that is independent of elevation or with little or no change in tree species richness with elevation change (Vázquez & Givnish, 1998; Martínez‐Camilo et al, 2018; Monge‐González et al, 2020). The diversity of shrubs, however, decreases slightly with elevation and increase with disturbance (Zhang et al, 2016; Bautista‐Bello et al, 2019), whereas climbers also seem to be more diverse at low elevations, but are associated with disturbed habitats (Dewalt et al, 2000; Bhattarai & Vetaas, 2003). By contrast, terrestrial herb diversity peaks at higher elevations and is usually higher in secondary vegetation (Gómez‐Díaz et al, 2017; but see Vázquez & Givnish, 1998).…”

Question Understanding the specific distribution patterns of vascular plants on different spatial scales is central in ecology and conservation. We evaluate the distribution patterns of five plant life forms (climbers, epiphytes, herbs, shrubs, and trees) along the elevation gradient and geographic space of a mountain system, analyzing climate, topography, and human disturbance to explain variation in the richness of each life form, and determine the contribution of each life form to total richness along the elevation gradient. Location Sierra Madre of Chiapas, southeastern Mexico. Methods We used linear models to evaluate the elevational pattern of richness for each life form, as well as total richness, and analyzed the effects of climate (water–energy dynamics, thermal range), topography (topographic heterogeneity), and disturbance (Human Influence Index) on variation in total richness as well as of each life form using Generalized Linear Models (GLM). We used Non‐Metric Multidimensional (Distance) Scaling to determine variation in species composition along the elevation gradient. Finally, the contribution of each life form to total richness was evaluated using GLM. Results We recorded 235 families, 1,439 genera, and 5,196 species. Total richness and the richness of each life form increased with increasing elevation. GLM explained a high proportion of the variation in the richness of each life form (34.3% for total richness; climbers 17.2%, epiphytes 44.9%, herbs 20.4%, shrubs 33.5%, and trees 24.9%). The proportion of richness of herbs and trees to total richness decreased, and the proportion of shrubs, epiphytes, and climbers increased with elevation. Climate largely determined species richness for all life forms, whereas disturbance was significant only for epiphyte richness. Conclusions Results suggest that mechanisms driven by climatic variables (especially thermal range) contribute to maintaining the richness of each life form. However, human disturbance modifies distribution patterns and leads to a decrease in epiphyte richness. The differential contribution of each life form to total richness along the elevation gradient presents a challenge for designing conservation strategies applicable to all plant groups.

“…Purpose: BIOVERA-Tree originated from the interdisciplinary research project BIOVERA, which aims at documenting and understanding biodiversity patterns along gradients of 2 altitude, climate, soil, and disturbance along an elevational transect at the Cofre de Perote in central Veracruz, Mexico (Carvajal-Hernández et al 2017, Gómez-Díaz et al 2017, Bautista-Bello et al 2019, Guzmán-Jacob et al 2020, Monge-González et al 2020. BIOVERA-Tree comprises forest plot data from eight elevational sites and three levels of forest-use intensity, namely old-growth, degraded, and secondary forests.…”

Here, we describe BIOVERA-Tree, a database on tree diversity, community composition, forest structure, and functional traits collected in 120 forest plots distributed along an extensive elevational gradient in Veracruz State, Mexico. BIOVERA-Tree includes information on forest structure from three levels of forest-use intensity, namely old-growth, degraded, and secondary forest, replicated across eight elevations from sea-level to near the tree line at 3500 m and on size and location of 4549 tree individuals with a diameter at breast height ≥ 5 cm belonging to 216 species, 154 genera, and 80 families. We also report measurements of eight functional traits, namely wood density for 143 species, maximum height for 216 species and leaf traits including: specific leaf area, lamina density, leaf thickness, chlorophyll content, and leaf area for 148 species and leaf dry matter content for 145 species. BIOVERA-Tree is a new database comprising data collected in a rigorous sampling design along forest-use intensity and elevational gradients, contributing to our understanding of how interactive effects of forest-use intensity and elevation affect tree diversity, community composition, and functional traits in tropical forests.
