“…At the same time, they placed this endemic area within the context of a larger, variable biome that spans a range of conditions and has considerable heterogeneity in its vegetation. Variability, in addition to environmental factors such as soil type, depth, and topographic complexity, may also help explain differences in species importance at any given site (Salas-Morales 2002, Segura et al 2003, Gallardo-Cruz et al 2005, Martinez-Cruz et al 2013.…”

We assessed woody plant communities in two widely separated forests in the tropical dry forest (TDF) biome of Mexico for evidence of similar patterns of species commonness and rarity. We used belt transects laid out along contour lines (i.e., constant elevation) and stratified across elevation gradients at sites in Jalisco and Oaxaca to sample woody plant species diversity, abundance, relative frequency and basal area. We assembled a combined species list and compared species found in both sites (shared) to species found in only one site, assessing whether the most and least common species at a site tended to be shared or unshared. Of the 8242 individuals sampled, 370 species or morpho‐species were identified, with 222 species recorded at the Jalisco site and 270 at the Oaxaca site—122 (33%) species were shared across sites. Abundance, frequency and basal area of shared species were greater on average than for unshared species, and were positively correlated across sites. A subset of 68 shared species (18%) accounted for over half of all individuals encountered at the two sites. Species in the most common quartile were more likely to be shared than expected by chance, while species in the least common quartile were less likely. A genus‐level analysis found similar patterns. Our findings suggest that the TDF of Pacific coast Mexico shows evidence of widespread dominance by a small subset of species. These findings have potentially important implications for predicting species composition, understanding the role of oligarchic species in ecological processes, and conserving rare species.

Por su vecindad con la Ciudad de México, que es el núcleo con mayor población del país, el estado de Morelos ha recibido una considerable presión sobre sus recursos forestales; el bosque tropical caducifolio es uno de los tipos de vegetación más impactados. A fin de conocer el estado de conservación de esta asociación, se realizó un estudio en el que se describe la estructura, riqueza y diversidad de especies de árboles en el municipio Tepalcingo de dicha entidad. Se censaron todos los árboles con un diámetro normal ≥ 10 cm en 34 sitios de muestreo de 500 m2 con una separación mínima entre ellos de 200 m, los cuales se ubicaron mediante un plano georreferenciado, que se cotejó en campo; cada uno de ellos fue identificado con estacas y una zanja en cruz en el centro, para facilitar su localización y remedición posterior. Los resultados indican la presencia de 883 individuos, pertenecientes a 50 especies y 20 familias, entre las cuales sobresale Fabaceae. Respecto al Índice de Valor de Importancia (IVI) destacan como taxa principales Lysiloma divaricatum (61.1), Amphipterygium adstringens (28.5), Conzattia multiflora (27.1), Mimosa benthami (21.5), Bursera copallifera (18.03); los valores de los índices de diversidad indican tendencias similares a las descritas para el número de especies.

Relating species richness to the structure of continuous landscapes: alternative methodological approaches

Numerous studies have focused on the relationship between landscape structure and plant diversity based on the patch‐mosaic landscape paradigm, by deriving structural data from classified images. Since the use of discrete classes poses limitations for predicting biodiversity patterns in complex, low human‐impacted ecosystems, two alternative methods have been used to analyze changes of landscape attributes in a continuum: moving‐window metrics and surface metrics (image texture). Here, we compare these two approaches for predicting richness of all plant species, legume species, legume trees, legume shrubs, legume forbs, and legume climbers across a tropical landscape in Mexico, based on the records of vascular plants in 250 10 × 10 m plots. Multiple regression and variance partitioning methods were used to analyze the effects of the two landscape descriptors (moving‐window and surface metrics), scale (400‐ and 200‐m moving‐window sides), and space (based on the extraction of principal coordinates of neighbor matrices’ vectors) on species richness. The predictive power of all metrics was relatively small for total species richness, but generally higher for legume species. For legume forbs, surface metrics‐based models indicated a direct association between species richness and landscape homogeneity. Moving‐window metrics were highly sensitive to the biological group and to spatial scale, likely due to a leftover effect of image classification procedures. Conversely, surface metrics were more independent from scale and taxonomy. Attempts to predict species richness in highly diverse, low human‐impacted tropical ecosystems more rapidly and accurately should better rely on surface metrics rather than on moving‐window metrics, in line with the continuous landscape paradigm.
