Diet overlap of the invasive House Sparrow and the native Rufous-collared Sparrow in an agroecosystem of Central Coast of Peru

We analyse the diet overlap of two species of sparrows in an agroecosystem of the Central Coast of Peru, one of the species is invasive House Sparrow, while the other is native Rufous-collared Sparrow. We show that although native species has a more diverse diet (H'= 2.07), than invasive specie...

El presente trabajo muestra que a pesar de que Z. capensis tiene una dieta más diversa (H’= 2.07) que P. domesticus (H’=1.63), presentan alta similitud entre ellas (Dmax=0.15, p>0.05). El índice de Schoener fue ɸ=0.73 y junto con en el análisis de escalamiento multidimensional no métrico muestran un amplio solapamiento en la dieta de ambos gorriones en los diferentes meses de evaluación. Estos resultados permiten concluir que existe un potencial impacto de la invasión de Passer domesticus sobre la especie nativa Zonotrichia capensis por presentar un marcado solapamiento del alimento.Universidad Nacional Mayor de San Marcos, Facultad de Ciencias Biológicas2018-05-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/htmlhttps://revistasinvestigacion.unmsm.edu.pe/index.php/rpb/article/view/1468710.15381/rpb.v25i2.14687Revista Peruana de Biología; Vol. 25 No. 2 (2018); 111-116Revista Peruana de Biología; Vol. 25 Núm. 2 (2018); 111-1161727-99331561-0837reponame:Revistas - Universidad Nacional Mayor de San Marcosinstname:Universidad Nacional Mayor de San Marcosinstacron:UNMSMspahttps://revistasinvestigacion.unmsm.edu.pe/index.php/rpb/article/view/14687/12878https://revistasinvestigacion.unmsm.edu.pe/index.php/rpb/article/view/14687/13786Derechos de autor 2018 Katherine Menacho, Letty Salinas, César Aranahttps://creativecommons.org/licenses/by-nc-sa/4.0info:eu-repo/semantics/openAccessoai:revistasinvestigacion.unmsm.edu.pe:article/146872018-06-23T13:33:28Z
