Endozoochory of seeds and invertebrates by migratory waterbirds in Oklahoma, USA

Given their abundance and migratory behavior, waterbirds have major potential for dispersing plants and invertebrates within North America, yet their role as vectors remains poorly understood. We investigated the numbers and types of invertebrates and seeds within freshly collected faecal samples (n...

We investigated the numbers and types of invertebrates and seeds within freshly collected faecal samples (n = 22) of migratory dabbling ducks and shorebirds in November 2008 in two parts of Lake Texoma in southern Oklahoma. Killdeer Charadrius vociferus were transporting a higher number and diversity of both plants and invertebrates than the green-winged teal Anas carolinensis. Ten plant taxa and six invertebrate taxa were identified to at least genus level, although viability was not confirmed for most of these taxa. Bryozoan statoblasts (from four species not previously recorded from Oklahoma) were especially abundant in killdeer faeces, while the ostracod Candona simpsoni was detected as a live adult in torpor in the teal faeces. Cyperaceae and Juncaceae were the most abundant plant families represented and Cyperus strigosus seeds germinated after extraction from killdeer faeces. This snapshot study underlines the importance of waterbirds as vectors of passive dispersal of many organisms and the need for more research in this discipline.Debido a su abundancia y a sus migraciones, las aves acuáticas tienen un gran potencial como dispersores de plantas e invertebrados en el Norte de América, pero su papel como vectores apenas se ha estudiado. Se investigó la cantidad y diversidad de invertebrados y semillas presentes en heces frescas (n = 22) de patos nadadores y limícolas recogidas en noviembre 2008 en dos zonas del Lago Texoma en el sur de Oklahoma. El chorlitejo colirrojo Charadrius vociferus transportó un número y diversidad de plantas y de invertebrados más alto que la cerceta americana Anas carolinensis. Se identificaron diez taxones de plantas y seis de invertebrados, al menos a nivel de género, aunque para la mayoría de los taxones no se comprobó su viabilidad. Los estatoblastos de briozoos fueron especialmente abundantes en las heces de chorlitejos, mientras que en las heces de una cerceta se recuperó vivo un ejemplar adulto de los trácodo Candona simpsoni.Las familias Cyperaceae y Juncaceae fueron las más representadas entre las semillas recuperadas, y las semillas de Cyperus strigosus germinaron tras extraerse de las heces. Este breve estudio subraya la importancia de las aves acuáticas como vectores de dispersión para muchos organismos, y la necesidad de más investigaciones en esta línea. 22013-01-0120132013-01-01Articlehttp://purl.org/coar/resource_type/c_6501VoRhttp://purl.org/coar/version/c_970fb48d4fbd8a85info:eu-repo/semantics/articleapplication/pdfhttps://ddd.uab.cat/record/111573reponame:Dipòsit Digital de Documents de la UABinstname:Universitat Autònoma de BarcelonaInglésengopen accesshttp://purl.org/coar/access_right/c_abf2Aquest material està protegit per drets d'autor i/o drets afins.
