Feeding behavior of the white-winged coot (Fulica leucoptera) along the middle Parana river inundation area, Argentina
The article describes the feeding behavior of the white-winged coot (Fulica leucoptera) by analyzing the stomach contents of 15 individuals with the stereoscopic microscope set to different degrees of taxonomic resolution: trophic spectrum was integrated by 14 taxonomical entities (4 vegetables and...

| description | The article describes the feeding behavior of the white-winged coot (Fulica leucoptera) by analyzing the stomach contents of 15 individuals with the stereoscopic microscope set to different degrees of taxonomic resolution: trophic spectrum was integrated by 14 taxonomical entities (4 vegetables and 10 animals); trophic diversity by stomach (H) oscillated between 0 and 1,95; accumulative trophic diversity (Hk) was 2,55; relative importance index (RII) values were Paspalum repens 253, Polygonum accuminatum 104, Belostoma 78, among others; trophic niche amplitude by season (estimated by using the Levins index) was 0,72 for summer, 0,46 for spring, 0,8 for fall and 0,86 for winter; prey percentages by size depicted 82% for organisms between 0 and 10 mm; an intestinal coefficient average (R) was 2,84. Based on those results, the author concludes that the Fulica leucoptera is an omnivorous species, mostly phytophagous. |

Se estudió la biología alimentaria de la gallareta chica Fulica leucoptera, analizando los contenidos estomacales de 15 individuos bajo lupa estereoscópica a diferentes grados de resolución taxonómica. Se calculó la diversidad trófica por estómago (H) y la diversidad trófica acumulada (Hk). Se aplicó el índice de importancia relativa (IRI). La amplitud trófica del nicho fue estimada según el índice de Levins. Se calculó el porcentaje de las presas por tamaño y el coeficiente intestinal (Ri). El espectro trófico resultó integrado por 14 entidades taxonómicas: 4 (fracción vegetal) y 10 (fracción animal). La diversidad trófica por estómago osciló entre 0 y 1,95. La diversidad trófica acumulada (HK) dio un valor de 2,55. Los valores del IRI fueron: Paspalum repens 253, Polygonum accuminatum 104, Belostoma 78, entre otros. La amplitud del nicho trófico por estación arrojó un valor de 0,72 para verano, 0,46 para primavera, 0,8 para otoño y 0,86 para invierno. El porcentaje de presas por tamaño mostró un 82% para organismos que oscilaron entre 0 y 10 mm. El promedio del coeficiente intestinal resultó ser de 2,84. Con base en los resultados obtenidos, se concluye que Fulica leucoptera es una especie omnívora básicamente fitófaga. 2021-11-10T01:00:00Z 2021-11-10T01:00:00Z 2011-06-14 Artículo revisado por pares info:eu-repo/semantics/publishedVersion http://purl.org/coar/resource_type/c_2df8fbb1 info:eu-repo/semantics/article http://purl.org/coar/version/c_970fb48d4fbd8a85 http://revistas.uan.edu.co/index.php/nodo/article/view/55 http://repositorio.uan.edu.co/handle/123456789/5540 spa http://revistas.uan.edu.co/index.php/nodo/article/view/55/625 Acceso abierto Attribution-NonCommercial-ShareAlike 4.0 International (CC BY-NC-SA 4.0) https://creativecommons.org/licenses/by-nc-sa/4.0/ info:eu-repo/semantics/openAccess http://purl.org/coar/access_right/c_abf2 application/pdf Universidad Antonio Nariño 2346-092X 1909-3888 REVISTA NODO; Vol. 5 Núm. 10 (2011); 113 - 121 |
