High-Andean wetland of Peru: Floristic diversity, primary net aerial productivity, ecological condition, and carrying capacity

Descripción del Articulo

Knowledge of the flora and usefulness of Andean wetlands for livestock farming is very scarce, which led to interest in evaluating floral diversity, net aerial primary productivity (NAPP), ecological condition and carrying capacity for alpacas (CCA), in three wetlands of the Shullcas sub-basin in Pe...

Floristic readings were taken in 10 quadrants distributed in a radial transect in each wetland and at typical times of the rainy and dry seasons. Phytomass cuts were made in regular periods of 30, 60, 90 and 120 days. Fourteen families of vascular plants with 33 genus and 41 species were found, the Shannon Wiener diversity index fluctuated between 2.28 ± 0.15 and 2.40 ± 0.17, the NAPP presented variation between the months evaluated in a range of 27.39 ± 33.73 to 97.86  ± 47.52 g dry material (DM)/m2, between cut-off periods from 132.12 ± 30.42 to 180.60 ± 32.89 g DM/m2 and between wetlands from 116.71 ± 34.6 to 192.18 ± 22.50 g DM/m2, all in good ecological condition; the CCA fluctuated between 1.38 ± 0.36 and 1.80 ± 0.40 alpacas/ha. The result obtained suggests that wetlands should be assessed for frequent periods in the year as a one-time replacement.El conocimiento de la flora y la utilidad de los humedales andinos para la ganadería es muy escaso, lo que llevó al interés de evaluar la diversidad florística, la productividad primaria neta aérea (PPNA), la condición ecológica y capacidad de carga para alpacas (CCA), en tres humedales de la subcuenca Shullcas en el Perú. Se realizó lectura florística en 10 cuadrantes distribuidos en transecto radial en cada humedal y en momentos típicos de las estaciones de lluvia y de seca. Se realizaron cortes de fitomasa en periodos regulares de 30, 60, 90 y 120 días. Se encontraron 14 familias de plantas vasculares con 33 géneros y 41 especies, el índice de diversidad Shannon Wiener fluctuó entre 2,28 ± 0,15 y 2,40 ± 0,17, la PPNA presentó variación entre los meses evaluados en un rango de 27,39 ± 33,73 a 97,86 ± 47,52 g materia seca (MS)/m2, entre periodos de corte desde 132,12 ± 30,42 a 180,60 ± 32,89 g MS/m2 y entre humedales desde 116,71 ± 34,6 a 192,18 ± 22,50 g MS/m2, todas ellas en condición ecológica buena; la CCA varió entre 1,38  ± 0,36 y 1,80  ± 0,40 alpacas/ha. El resultado obtenido sugiere que los humedales deben ser valorados por periodos frecuentes en el año en reemplazo de una sola vez.Universidad Nacional de Trujillo2020-06-08info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://revistas.unitru.edu.pe/index.php/scientiaagrop/article/view/292210.17268/sci.agropecu.2020.02.08Scientia Agropecuaria; Vol. 11 No. 2 (2020): Abril-Junio; 213-221Scientia Agropecuaria; Vol. 11 Núm. 2 (2020): Abril-Junio; 213-2212306-67412077-9917reponame:Revista UNITRU - Scientia Agropecuariainstname:Universidad Nacional de Trujilloinstacron:UNITRUspahttp://revistas.unitru.edu.pe/index.php/scientiaagrop/article/view/2922/3088http://revistas.unitru.edu.pe/index.php/scientiaagrop/article/view/2922/3266Derechos de autor 2020 Scientia Agropecuariainfo:eu-repo/semantics/openAccess2021-06-01T15:35:35Zmail@mail.com -
