Helminth communities of mottled ducks (Anas fulvigula) from Florida and Texas were species rich and diverse. The helminth component community in the mottled duck population from Texas contained more species than were found in the Florida host population. However, infracommunities of birds from Florida and Texas contained 9.5 ± 0.7 (mean ± SE) and 9.3 + 0.7 species, respectively. Similarity indices indicated less commonality of helminth species between the 2 host populations; 23 of the 42 species found across the 2 populations co-occurred. Eight helminth species from each host population were recurrent group or associate members; however, only 3 species (Amidostomum acutum, Capillaria contorta, and Tetrameres spp.) maintained group membership across both host populations. Maritrema paracadiae and Psilochasmus oxyurus were absent in birds from Florida but were recurrent group members in the host population from Texas. Only 2 recurrent group members (A. acutum and Epomidiostomum uncinatum) in birds from Florida were members of the same feeding guild and shared the same microhabitat. Three distinct feeding guilds, each containing 2 species, were found in birds from Texas. Results suggest that habitat diversity of the host plays an important part in determining species richness; however, important helminth species in both mottled duck populations are those commonly found in other Anatini from North America.

Abstract Little is understood concerning the effects regional isolation and habitat loss have had upon the genetic structure of Mottled Ducks (Anas fulvigula), a nonmigratory waterfowl species with a limited distribution. Our objective was to identify nuclear DNA-based markers for Mottled Ducks and determine levels of subdivision among populations in Florida. We screened 13 microsatellite primer pairs and identified six microsatellite loci that were variable in Mottled Ducks. These markers revealed a low level of genetic differentiation and a high level of genetic exchange among four Mottled Duck subpopulations within Florida. Over all populations, single-locus expected heterozygosities over the six loci surveyed ranged from 0.13–0.85. There were no significant differences in gene frequencies among the populations examined, and the Fst over 5 biparental loci was not different from zero. Our analysis of the Florida Mottled Duck population indicated high levels of heterozygosity and no evidence of genetic subdivision among breeding units. Polimorfismo en Microsatélites y Estructura Genética en Poblaciones de Anas fulvigula Resumen. Se tiene escaso conocimiento acerca de los efectos del aislamiento regional y de la pérdida de hábitat sobre la estructura genética de poblaciones de Anas fulvigula, un ave acuática no migratoria de distribución restringida. Nuestro objetivo fue identificar marcadores genéticos de ADN para A. fulvigula y determinar los niveles de subdivisión entre poblaciones en Florida. Examinamos 13 pares de iniciadores (i.e., primers) para microsatélites e identificamos seis loci que fueron variables en A. fulvigula. Estos marcadores revelaron un bajo nivel de diferenciación genética y un alto grado de intercambio genético entre cuatro subpoblaciones de A. fulvigula en Florida. Para todas las poblaciones, la heterocigocidad esperada en un locus varió entre 0.13–0.85 para los seis loci examinados. No hubo diferencias significativas en las frecuencias génicas entre las subpoblaciones examinadas, y el valor de Fst para los 5 loci biparentales no fue diferente de cero. Nuestros análisis de las poblaciones de A. fulvigula de Florida indicaron altos niveles de heterocigocidad y no mostraron evidencia de subdivisión genética entre las unidades reproductivas.
