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...

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.application/pdfspaUNIVERSIDAD ANTONIO NARIÑOhttps://revistas.uan.edu.co/index.php/nodo/article/view/55/625https://creativecommons.org/licenses/by-nc-sa/4.0http://purl.org/coar/access_right/c_abf2REVISTA NODO; Vol. 5 Núm. 10 (2011); 113 - 1212346-092X1909-3888Aves acuáticasespectro tróficonicho y uso de hábitatAquatic birdstrophic spectrumecological nichehabitat useFeeding behavior of the white-winged coot (Fulica leucoptera) along the middle Parana river inundation area, ArgentinaBiología alimentaria de la gallareta chica Fulica leucoptera en el valle de inundación del río Paraná medio, Argentinainfo:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArtículo revisado por pareshttp://purl.org/coar/resource_type/c_6501http://purl.org/coar/resource_type/c_2df8fbb1http://purl.org/coar/version/c_970fb48d4fbd8a85F.
