“…The sample sites in this protection and land use category had a high number of individuals but low species richness, one of the lowest β-diversity values, and the most homogeneous composition. This corresponds to a pattern identified as homogenization by anthropic effects, where the species that are either resistant to disturbance or favored by the ecological conditions of open areas tend to become dominant and homogenize the composition of the plant community (Mesa-Sierra et al 2020, Arroyo-Rodríguez et al 2013. Thus, the use of riparian vegetation can reduce plant abundance, cause the extinction of the most sensitive local species, or favor generalist or invasive species (Cabette et al 2017).…”

Background: Rivers and their associated vegetation are considered highly complex natural systems representing high biodiversity areas that work as biological corridors. Nevertheless, riparian vegetation of the Monarch Butterfly Biosphere Reserve (MBBR) has not been studied nor considered in the reserve’s management program. Questions: Which is the composition, structure, diversity, and state of conservation of the riparian vegetation of the MBBR? Study site and dates: The Senguio Microbasin, part of Sierra Chincua Priority Terrestrial Region, within the MBBR, in central México. 2016-2017. Methods: Using high-resolution imagery from 2014, we identified five joint categories in relation to the protection status (Core Zone, Buffer Zone, and Influence Area) and land use (conserved forest, highly disturbed forest, and farmland). We sampled three sites per category (N = 15) to analyze the composition, richness, and α- and β-diversity of the riparian communities. Results: We registered 108 species, 46 genera, and 18 families, of which 98 % are native and 2 % exotic. Richness and α-diversity were not significantly different among sites, but the composition and β-diversity showed significant differences depending on land use. The riparian vegetation is well conserved both in the Reserve´s Core and Buffer zones, and preserves high coverage, species richness, and individuals’ abundance. Conclusions: The riparian vegetation of the Senguio Microbasin hosts a biodiversity richness critical for the ecosystem’s health and evidences the relevance of considering the human use of the riparian systems to succeed in the conservation strategies.

“…En los últimos 25 años, se ha generado información sobre los tres elementos básicos de la diversidad, es decir, la riqueza, la abundancia y la composición de los BTC y BTSC de México. A pesar de las variaciones en los diseños de muestreo y los análisis de diversidad utilizados, el número de especies ha sido la medida básica, intuitiva y directa de la diversidad en varios de los estudios (e.g., Trejo & Dirzo 2002, Pineda-García et al 2007, Méndez-Toribio et al 2014, mientras que la distribución de la abundancia de las especies ha sido destacada en otros (e.g., Trejo 1998, Pineda-García et al 2007, Dzib-Castillo et al 2014, Méndez-Toribio et al 2014, Mesa-Sierra et al 2020. Algunos estudios han estimado índices de entropía para explicar los patrones de diversidad alfa (e.g., Dzib-Castillo et al 2014, Méndez-Toribio et al 2014.…”

Diversidad de plantas leñosas en el bosque tropical caducifolio y subcaducifolio de Sierra de Vallejo, Nayarit, México

et al. 2021

View full text Add to dashboard Cite

Antecedentes: Los bosques tropicales caducifolios y subcaducifolios se distingue por su diversidad florística, su notable concentración de especies endémicas, alto recambio y baja similitud de especies. Preguntas: ¿Cuál es la diversidad alfa y beta de las especies de plantas leñosas del bosque tropical caducifolio y subcaducifolio en Sierra de Vallejo? Sitio y período de estudio: Sierra de Vallejo forma parte del Área de Protección de Recursos Naturales, Sierra de Vallejo-Río Ameca, Nayarit-Jalisco; agosto 2017 a mayo 2018. Métodos: Se establecieron 15 transectos de 0.1 ha, identificando a cada planta leñosa con diámetro a la altura del pecho (DAP = 1.30 m) ≥ 3 cm. La diversidad alfa se analizó considerando la diversidad verdadera basada en el número efectivo de especies y curvas de rango abundancia. La diversidad beta se analizó con similitud, recambio y anidamiento. Resultados: Se registraron 1,556 individuos, pertenecientes a 45 familias, 99 géneros y 126 especies; 22 especies son endémicas a México, una endémica a la región, 84 nativas y cuatro exóticas. Los sitios se caracterizaron por presentar una baja riqueza de especies observadas (13-37 especies), alta variación en la abundancia (44-229 individuos), una baja diversidad verdadera (q0, 18-49 especies), alto recambio (91-96 %), bajo anidamiento (0.9-1 %) y baja similitud (8 %). Conclusiones: Los valores de diversidad florística muestran la importancia de preservar la mayor cantidad de áreas con bosque tropical dentro de Sierra de Vallejo, reforzando las estrategias de conservación y manejo del bosque dentro de esta Área Natural Protegida de Recursos Naturales.
