Spot-flanked Gallinule Porphyriops melanops (Aves: Rallidae) feeding biology in the Middle Parana River flood-plain, Argentina

A proposal for sustainable usage of rails population should take into account complete alimentary requirements. Hence, the purpose of the following study was to determine the feeding biology of the Spot-flanked Gallinule Porphyriops melanops. The research was conducted on 11 stomach contents to find...

Hence, the purpose of the following study was to determine the feeding biology of the Spot-flanked Gallinule Porphyriops melanops. The research was conducted on 11 stomach contents to find out trophic diversity by stomach (H), accumulated trophic diversity (Hk), Relative Importance Index (IRI), alimentary efficiency, prey size percentage and intestinal coefficient (Ri). The resultant spectrum was composed by 10 taxonomical entities, 7 animal fractions and 3 vegetable fractions; trophic diversity by stomach (H) ranged between 0 and 1, while accumulated trophic diversity (Hk) was 2,57; main IRI values were as follows: Polygonum accuminatum 1204, Planorbidae 872 and Paspalum repens 451; alimentary efficiency was 97,5%; more frequent prey sizes oscillated between 0 and 10 mm; habitat preference was 2,4; and the average intestinal coefficient was 2,79.Una propuesta de uso sustentable de las poblaciones de rálidos debe incorporar el conocimiento de sus requerimientos alimentarios. Así, el propósito de este trabajo fue analizar la dieta de la pollona pintada Porphyriops melanops. Se analizaron un total de 11 estómagos, para los cuales se calculó la diversidad trófica por estómago (H), la diversidad trófica acumulada (Hk), el índice de importancia relativa (IRI), el porcentaje de las ingestas por tamaño y el coeficiente intestinal (Ri). El espectro resultó integrado por 10 entidades taxonómicas, de las cuales 7 correspondieron a la fracción animal y 3 a la fracción vegetal. La diversidad trófica por estómago (H) osciló entre 0 y 1 mientras que la diversidad trófica acumulada (Hk) fue de 2,57. Los principales valores del IRI fueron: Polygonum accuminatum 1204, Planorbidae 872 y Paspalum repens 451. La eficiencia alimentaria fue del 97,5% mientras que del tamaño más usual de presas ingeridas osciló entre 0 y 10 mm. El valor obtenido de preferencia de hábitats fue de 2,4. Mientras que el promedio del Ri fue de 2,79.application/pdfspaUniversidad Antonio Nariñohttp://revistas.uan.edu.co/index.php/nodo/article/view/78/612346-092X1909-3888REVISTA NODO; Vol. 7 Núm. 13 (2012); 85 - 92Aquatic birdstrophic spectrumecological nichehabitat useAves acuáticasespectro tróficonicho y uso de hábitatSpot-flanked Gallinule Porphyriops melanops (Aves: Rallidae) feeding biology in the Middle Parana River flood-plain, ArgentinaBiología alimentaría de la pollona pintada Porphyriops melanops (Aves: Rallidae) en el valle de inundación del río Paraná medio, ArgentinaArtículo revisado por paresinfo:eu-repo/semantics/publishedVersionhttp://purl.org/coar/resource_type/c_2df8fbb1info:eu-repo/semantics/articlehttp://purl.org/coar/version/c_970fb48d4fbd8a85123456789/5559oai:repositorio.uan.edu.co:123456789/55592024-10-09 22:45:30.538https://creativecommons.org/licenses/by-nc-sa/4.0/Acceso abiertometadata.onlyhttps://repositorio.uan.edu.coRepositorio Institucional UANalertas.repositorio@uan.edu.co
