The first natural history data is reported for the tortoise beetle, Cyrtonota serinus (Erichson, 1847) (Chrysomelidae: Cassidinae: Mesomphaliini). An Ipomoea sp. (Convolvulaceae) is recorded as the host plant. Larvae and adults feed on the leaves. Larvae retain an exuvio-fecal shield and are gregarious. Adults are sexually dimorphic and polymorphic in sizes and coloration.

Population dynamics studies raise relevant data to understanding ecological aspects and natural history of species as well as better conservation strategies. Using two scorpions species, Troglorhopalurus translucidus Lourenço, Baptista & Giupponi, 2004 and Troglorhopalurus lacrau (Lourenço & Pinto-da-Rocha, 1997) from Chapada Diamantina, Bahia state, Brazil, we estimate populacional parameters through mark and recapture methodology, and Jolly-Seber estimator. In addition, data on both species as sexual ratio, reproductive biology, growth, longevity, feeding habitats, and seasonality were analyzed in the caves and afterwards compared to other scorpion species as well as other arachnids. We captured and marked 82 specimens of T. translucidus and 65 specimens of T. lacrau. Population estimates were 361 ± 199 individuals to T. translucidus and 333 ± 252 to T. lacrau. Population estimates were considered high for the troglobitic scorpions when compared to subterranean arachnids or even with epigean species of scorpions. Both troglobitic scorpions featured remarkable differences in relation to epigean scorpions as higher longevity, longer reproductive period, slower growth. Besides T. translucidus showed marked seasonality with populational variations in rainy seasons in contrast to T. lacrau with populational stability. Suppl. material 1

Little is known about the biology of the tick, Ixodes hexagonus Leach 1815 a nest ectoparasite of hedgehogs. This is surprising as it is frequently encountered on domestic pets and is a known vector of various tick borne pathogens. This review examines the biology, life-history and population dynamics of I. hexagonus. The ability of I. hexagonus to transmit pathogens between hedgehog hosts means it could play an important role in the persistence of tick borne diseases. The favoured hedgehog hosts of I. hexagonus are frequently found in suburban habitats, thus it may be important in the maintenance of disease cycles in such areas.

Abstract We estimated annual apparent survival, recruitment, and rate of population growth of breeding Ruby-throated Hummingbirds (Archilochus colubris), while controlling for transients, by using 18 years of capture-mark-recapture data collected during 1984–2001 at Hilton Pond Center for Piedmont Natural History near York, South Carolina. Resident males had lower apparent survival (0.30 ± 0.05 SE) than females (0.43 ± 0.04). Estimates of apparent survival did not differ by age. Point estimates suggested that newly banded males were less likely than females to be residents, but standard errors of these estimates overlapped (males: 0.60 ± 0.14 SE; females: 0.67 ± 0.09). Estimated female recruitment was 0.60 ± 0.06 SE, meaning that 60% of adult females present in any given year had entered the population during the previous year. Our estimate for rate of change indicated the population of female hummingbirds was stable during the study period (1.04 ± 0.04 SE). We suggest an annual goal of ≥64 adult females and ≥64 immature females released per banding area to enable rigorous future tests for effects of covariates on population dynamics. Development of a broader cooperating network of hummingbird banders in eastern North America could allow tests for regional or metapopulation dynamics in this species. Sobrevivencia Anual y Reclutamiento en una Población del Picaflor Archilochus colubris Excluyendo el Efecto de Individuos Ocasionales Resumen. Estimamos la sobrevivencia anual aparente, reclutamiento y tasa de crecimiento en una población reproductiva del picaflor Archilochus colubris, controlando por la presencia de individuos ocasionales. Utilizamos datos de 18 años de captura-marcaje-recaptura colectados entre 1984 y 2001 en Hilton Pond Center for Piedmont Natural History en cercanías de York, Carolina del Sur. Los machos residentes presentaron una sobrevivencia aparente menor (0.30 ± 0.05 EE) que las hembras (0.43 ± 0.04). Las estimaciones de la sobreviviencia aparente no difirieron entre edades. Estimaciones puntuales sugirieron que los machos marcados por primera vez tuvieron una menor probabilidad de ser residentes que las hembras, pero los errores estándar de estas estimaciones se sobrepusieron (machos: 0.60 ± 0.14 EE; hembras: 0.67 ± 0.09 EE). Para las hembras el reclutamiento estimado fue 0.60 ± 0.06 EE, lo que significa que el 60% de las hembras adultas presentes en un año determinado entraron a la población durante el año anterior. Nuestra estimación de la tasa de cambio indicó que la población de picaflores hembra fue estable durante el período de estudio (1.04 ± 0.02 EE). Para permitir futuras pruebas rigurosas sobre las covariables asociadas a las dinámicas poblacionales, sugerimos una meta anual de ≥64 hembras adultas y ≥64 hembras inmaduras liberadas por área de anillado. La creación de una amplia red cooperativa de anilladores de picaflores en el este de Norteamérica podría permitir estudiar y entender mejor las dinámicas regionales o metapoblacionales de esta especie.
