Stable Isotope Technique

We used gut-content and stable-isotope techniques to determine diets of shorebirds staging at a prairie wetland complex. Stable-isotope ratios for carbon (13C/12C) and nitrogen (15N/14N) varied greatly within and among prey types and shorebirds, depending on location within the complex. Both dietary techniques suggested that Long-billed Dowitchers (Limnodromus scolopaceus) and Stilt Sandpipers (Calidris himantopus) ate mostly invertebrates, whereas Hudsonian (Limosa haemastica) and Marbled godwits (Limosa fedoa) ate mainly Potamogeton pectinatus tubers. In comparison, the stable-isotope technique indicated that godwits, especially juvenile Marbled Godwits, ate more invertebrates than is indicated by the gut-content analysis. The discrepancies between methods reflect the potential for bias in the application of these techniques. Researchers using stable isotopes to assess migratory shorebird diets should be aware of possible complications arising from isotopic variability within prey types, even over small geographic ranges. High isotopic variability at inland agro-wetland complexes might preclude reliable isotopic assessment of shorebird diets, especially long term. Rhizivory in godwits may be more common than is generally recognized, especially at inland stopovers during autumn migration in both North America and Eurasia, and should be factored into conservation initiatives for these species.

Eleven specimens of a new genus of cyclocoelid, Selfcoelum limnodromi n. gen., n. sp. (Digenea: Cyclocoelidae: Cyclocoelinae) from the air sacs of a long-billed dowitcher, Limnodromus scolopaceus, collected from the Cheyenne bottoms in Oklahoma and deposited at the Howard W. Manter Laboratory, University of Nebraska by Dr. Teague Self, former professor, Department of Zoology, University of Oklahoma, Norman, Oklahoma were examined. The new genus has an intertesticular ovary placing it in Cyclocoeolinae. It is most similar to species of Morishitium and Neohyptiasmus in having a postpharyngeal genital pore and vitelline fields that are not confluent posteriorly. However, unlike species of either of these 2 genera, the ovary of S. limnodromi n. gen., n. sp. forms a triangle with the testes as is found in species of Cyclocoelum where the genital pore is prepharyngeal rather than postpharyngeal. Selfcoelum n. gen. further differs from Morishitium by having uterine loops that surpass the ceca and vitelline fields laterally approaching the body wall instead of being intercecal, and from Neohyptiasmus by having testes that are rounded and entire instead of being lobed. A revised key to the Cyclocoelinae is provided to include the 2 additional genera that have been recently described from North America, Neoallopyge and Selfcoelum.

During a study of the endohelminths of wading birds from the Texas Gulf coast, 5 specimens of an undescribed species of Haematotrephus (Cyclocoelidae) were studied and described. These specimens were collected by Dr. J. Teague Self, former professor, Department of Zoology, University of Oklahoma, Norman, Oklahoma from the air sacs of a long-billed dowitcher, Limnodromus scolopaceus, that was collected from the Cheyenne Bottoms, Roger Mills County, Oklahoma on August 3, 1963 and deposited in the Manter Laboratory of Parasitology. Haematotrephus limnodromi n. sp. can be distinguished from all the other species in the genus that lack an oral sucker (H. capellae, H. chengi, H. dollfusi, H. fasciatum, H. kossacki, H. lanceolatum, H. longisacculatum, H. nebularium, H. nigropunctatum, and H. phaneropsolus) by having intertesticular uterine loops. Corpopyrum brazilianum (originally described as Cyclocoelum brazilianum) is transferred as the second species in Selfcoelum, Corpopyrum dendrei is transferred to Neohaematotrephus, and Haematotrephus facioi is transferred to Wardianum. This is the first report of a species of Haematotrephus from a species of Limnodromus.

Nutrient Reserves

Abstract Inland-migrating shorebirds rely on wetlands as stopover sites to replenish nutrient reserves. Because wetlands are spatially and temporally dynamic, shorebirds may accumulate highly variable lipid reserves. We compared lipid reserves among four shorebird species (American Avocets [Recurvirostra americana], Long-billed Dowitchers [Limnodromus scolopaceus], Least Sandpipers [Calidris minutilla], and Western Sandpipers [C. mauri]) collected from playa wetlands in the southern Great Plains during spring 1993 and 1994. Because playas are ephemeral, we had the opportunity to examine the influence of a variable environment (a wet year and a dry year) on lipid reserves. Additionally, we examined the influence of different migration distances and strategies, and body sizes on lipid reserves. Western Sandpipers had the highest lipid reserves (41%–50%) and Dowitchers had the lowest reserves (18%). Least and Western Sandpipers had 7%–9% higher lipid reserves in the wet year than dry year. Thus, small-bodied shorebirds may be more affected by variable habitat conditions than large-bodied shorebirds because of their higher mass-specific metabolic rates. Reservas Lipídicas de Aves Playeras Migrantes Durante la Primavera en Humedales del Sur de la Gran Planicie Resumen. Las aves playeras que migran tierra adentro necesitan de humedales como lugares de escala migratoria para recuperar sus reservas de nutrientes. Debido a que los humedales son espacial y temporalmente dinámicos, las aves playeras pueden acumular lípidos como reserva de forma muy variable. En este estudio comparamos las resevas lipídicas entre cuatro especies de aves playeras (Recurvirostra americana, Limnodromus scolopaceus, Calidris minutilla y C. mauri) colectadas en los humedales “playa” de la parte sur de la gran planicie durante la primavera de 1993 y 1994. Debido a que estos humedales son ambientes efímeros, tuvimos la oportunidad de examinar la influencia de un ambiente variable (un año húmedo y un año seco) sobre las reservas lipídicas de las aves. Además, examinamos la influencia de distintas distancias y estrategias de migración y del tamaño corporal sobre las reservas. La especie con las mayores reservas lipídicas fue C. mauri (41%–50%) y la especie con las menores reservas fue L. scolopaceus (18%). Las dos especies de Calidris presentaron reservas lipídicas un 7%–9% mayores en el año húmedo que en el año seco. Por tanto, las aves playeras de tamaño pequeño podrían verse más afectadas por condiciones ambientales variables que las de tamaño grande como consecuencia de sus mayores tasas metabó licas con respecto al peso.
