“…Similarly, the experimental study of Pryke and Rollins (2012) demonstrated positive effects of diet quality on hemoglobin concentrations in nestling Blue-faced Parrot Finches (Erythrura trichroa). Unusually low hemoglobin concentrations were also recorded in Great Tit chicks exposed to high environmental pollution (Nyholm et al 1995). Therefore, Common Snipe with lower hemoglobin concentrations may be of generally lower physical condition or inferior genetic quality and, for this reason, exhibit reduced developmental stability resulting in a high degree of molt asymmetry.…”

“…Subsequently, samples were dried at 60°C for 24 h (Camargo 1991) to determine the dry weight. Samples prepared in this way were digested in a 4:1 mixture of 65 % nitric acid and 70 % perchloric acid (Nyholm et al 1995), and then diluted in 10 ml of deionized water.…”

Hydropsyche angustipennis (Insecta, Trichoptera) larvae were used as indicators of stream contamination in the city of Łódź, Poland. The larvae of H. angustipennis were present at 9 sampling sites established for this study. Significant differences between the sampling sites were noted for environmental parameters as well as concentration of chemicals in water and biodiversity of aquatic invertebrates. Statistical analyses showed significant correlations between quantity and quality of water pollutants and density of H. angustipennis larvae, concentration of metals in larval bodies, and the appearance of morphological anomalies in tracheal gills and anal papillae. In comparison to literature data, the level of contaminants in water, including heavy metals, for each of the studied streams of Łódź was surprisingly low while concentration of these metals in the whole bodies of H. angustipennis larvae was very high. Some of the heavy metals present in the water might be identified only after conducting analyses of their concentration in the larval bodies. Therefore, long life cycle of H. angustipennis and heavy metal tolerance with a possibility of their accumulation in the larval bodies may constitute a support to traditional chemical assessment of water quality or traditional biomonitoring.

The degree of asymmetry in feather replacement may be considered a reliable measure of developmental instability of avian molt. Although empirical evidence exists for the fitness consequences of molt asymmetry, the proximate cause of asymmetrical molt remains unknown. We tested for the possibility of a link between asymmetry in feather replacement and hemoglobin concentration of first-year Common Snipe {Gallinago gallinago) during the partial postjuvenile molt. Advancement and symmetry of molt were determined for 637 first-year Common Snipe captured at Jeziorsko reservoir, central Poland, during autumn migration. We found that the probability of asymmetrical molt did not vary with date of capture {W= 1.66, P = 0.20), but Common Snipe with lower hemoglobin concentrations had a higher probability of asymmetrical molt {W •= 5.22, P = 0.022). Because Common Snipe molt during migration, high oxygen-carrying capacity of blood is presumably necessary to meet aerobic demands of the tissues during long-distance flights. We suggest that under these conditions, low hemoglobin concentrations may lead to an acute organismal hypoxia causing disruptions in developmental homeostasis, such as asymmetrical feather replacement.La Baja Capacidad de Carga de Oxígeno en la Sangre Podría Incrementar la Inestabilidad en el Desarrollo de la Muda en Aves Vadeadoras Migratorias RESUMEN.-El grado de asimetría en el reemplazo de las plumas podría ser considerado como una medida confiable de la inestabilidad en el desarrollo de la muda en las aves. Aunque existe evidencia empírica de las consecuencias de la asimetría en la muda sobre la aptitud, la causa próxima de la muda asimétrica permanece desconocida. Evaluamos la posibilidad de que la asimetría en el reemplazo de las plumas pudiese estar ligada con la concentración de hemoglobina en individuos de Gallinago gallinago en su primer año, durante la muda parcial post-juvenil. El avance y la simetría de la muda fueron determinados para 637 individuos en su primer año de vida capturados en la reserva Jeziorsko, Polonia central, durante la migración de otoño. Encontramos que la probabilidad de presentar muda asimétrica no varió con la fecha de captura {W= 1.66, P = 0.20), pero los individuos con menores concentraciones de hemoglobina tuvieron una mayor probabilidad de presentar muda asimétrica {W= 5.22, P = 0.022). Debido a que G. gallinago muda durante la migración, se presume que necesita de una alta capacidad de carga de oxígeno en la sangre para cumplir las demandas aeróbicas de los tejidos durante los vuelos de larga distancia. Sugerimos que, bajo estas condiciones, las bajas concentraciones de hemoglobina podrían llevar a una hipoxia organísmica aguda y causar trastornos en la homeostasis del desarrollo, como un reemplazo asimétrico en las plumas.MoLT IS AN energetically demanding stage of the avian annual performance and low body mass were also observed in European cycle (Williams and Swaddle 2003).
