“…Site six was presented as the most diverse area, expressed through the Shannon index, with higher equitability (Equity) and lower dominance (Simpson). These results correspond with what was reported by Valdés et al (2014) and García et al (2016) for pine forests, attributing the low diversity to the influence of anthropization and ecosystem type. According to Alvis Gordo (2009), natural tropical forests are heterogeneous and are made up of a high diversity of species, with different successional ages: sapling, latizal and fustal.…”

Objective: To characterize the understory species associated with a pine-oak forest in the Sierra Mariscal region, Chiapas. Design/methodology/approach: Six 40 m2 subplots were established to evaluate the cover, abundance and identity of shrub, herbaceous and sapling components of the understory. Floristic diversity was determined. The level of disturbance was evaluated using the observation method. An analysis of variance and comparison of means by Tukey (p<0.05) between structural variables was applied. The relationship between disturbance levels and study sites was performed by correspondence analysis. Results: The understory is composed of five tree species, three herbaceous and two shrub species. The largest diameter (p≤0.0001 and F=27.6) corresponds to herbaceous Cortaderia seolloana (5.38±0.94 cm) and Petiridium aquilinum (4.5±0.96 cm). The greatest height corresponds to Quercus sp. saplings (126.3±75.9 cm) and the herbaceous Cenchurus sp. (110.2±54.1 cm) and Peteridium aquilinum (91.7±40.9 cm), the latter having the highest density (4050 ind. ha-1) and cover (16.2%). Floristic diversity was low in all six sites. Site six was the most diverse and site three the most disturbed. Study limitations/implications: The study comprised a limited and insufficient area to generalize the conditions of pine-oak forests in the Chiapas highlands. It is suggested to expand the study universe and increase the number of replications. Findings/conclusions: Variability in understory structure and composition was found that corroborates the relationship between forest diversity and disturbance.

“… Benítez-Malvido and Martínez-Ramos (2003) indicated that vegetation fragmentation allows for greater species richness, because it creates more distinct habitats to occupy. These results correspond to those obtained by Valdés-Sáenz et al. (2014) in forest areas with different levels of disturbance, and Patiño et al.…”

“…The pioneer species of secondary forests that are typical of ecological succession can be considered as indicative of the changes that have occurred in the forest areas of the upper Puyo River micro-basin. This corresponds to what was stated by Valdés-Sáenz et al. (2014) , namely that the IVI values may be a reflection of the anthropization that some species of commercial interest are subject to.…”

The evergreen forests of the Ecuadorian Amazon Region are altered by anthropogenic and natural factors. This provokes the need to look for tools that facilitate decision-making in support of restoration. We characterized the ecological structure and distribution of an evergreen Amazonian-Andean forest in the upper Puyo River micro-basin as a base for establishing an ecological quality index. The inventory was assessed using transects 0.1 ha (10 m × 100 m), registering the species with diameters at 1.30 m height ≥10 cm. We encountered a high degree of richness (30 families, 65 species and 322 individuals). The structural parameters indicated the predominance of a heterogeneous forest, with characteristics belonging to disturbed forests. A non-continuous vertical distribution pattern was found, determined by 78% of the species in a single stratum. The mixing ratio resulted in a higher proportion (1:5) for the lower class. The species Wettinia maynensis , Alchornea glandulosa , Miconia splendens , Piptocoma discolor and Inga velutina had the highest ecological value. The principal components analysis distinguished the abundance of species that had a high correlation with the sites and a distinct pattern was found in transect three. We developed the Structural Ecological Quality Index, which considers the social position of various species as well as their ecological importance, to reflect alterations in structural parameters. Abundance was concentrated in the 10–20 m strata (10–20 cm diameter class), which showed the presence of disturbance indicator species and a low ecological value. This indicated the real value of the historical succession of the forest, thus we recommend carrying out a restoration of this important reservoir.

“…En este escenario es necesario promover acciones de restauración que permitan la rehabilitación de los sitios más perturbados a partir de grupos núcleos de familias botánicas para cada condición local. Estos resultados se corresponden con lo descrito por Valdés-Sáenz et al (2014), Gutiérrez y Becerra (2018) y Vega (2020), quienes refieren que las perturbaciones antrópicas alteran sensiblemente los patrones de estructura y composición en las comunidades vegetales.…”

Se evaluó la biomasa aérea acumulada en lo concerniente a familias botánicas en un bosque siempreverde piemontano sometido a diferentes grados de intervención en la zona alta de la microcuenca del río Puyo. En cinco transectos de 0.1 ha se registraron las especies con DAP ≥ 10 cm. Se encontró menor número de familias en sitios con alto grado de perturbación. La biomasa aérea varió de 161.84 a 339.70 Mg.ha-1, presentándose mayor acumulación en individuos de menor clase diamétrica. Las familias con mayor índice de valor de importancia de biomasa fueron Moraceae, Arecaceae y Euphorbiaceae, reconocidas por su potencial en cuanto a estructura y carbono. El análisis de correspondencia canónica sin tendencia (DCA) indicó variación en la contribución de biomasa para cada sitio, existiendo un pequeño número de familias para mantener las reservas de carbono. Los resultados de este estudio brindan información relevante que facilita la toma de decisiones con respecto la restauración de sitios perturbados.
