Geographic Segregation And Evidence Of Density-Dependent Changes In Sex Ratios In An Abundant Colonial Waterbird, Brian S. Dorr, Katie C. Hanson-Dorr, Travis L. Devault, Alban Guillaumet, Scott C. Barras

Demographic information, such as geographic segregation of sexes and sex ratio data, is needed to develop, model and evaluate conservation and management strategies for wildlife. A variety of physiological, behavioral and environmental factors can influence segregation of sexes and sex ratios, many of which originate with density- dependent processes. Departure from 50:50 sex ratios of double-crested cormorants (Phalacrocorax auritus) collected during control efforts in breeding and wintering areas across their eastern range of the USA were evaluated using using a Z-test as well as Stouffer’s weighted Z-tests. In addition, a specifically-designed randomization test was used to evaluate density-dependent effects on …

Spiders play an important role in regulating insect pests in the agricultural ecosystem. There are a large number of species, many of them with high population densities. A survey was conducted in the Ayya Nadar Janaki Ammal College campus from January, 2011 - March, 2011. 29 individuals were collected representing 11 families and 21 genera. From these, 25 species were present throughout the campus; however, only 5 of these were taken in the ground, they are the ground dwellers. Peucetia viridana (Stolizcka), Oxyopes hindostanicus (Tikader), Lycosa pseudoannulata (Bosenberg) and Plexippus petersi, were common. P. viridana was the dominant species followed …
