    To date over peer-reviewed articles have resulted from analysis done with Christmas Bird Count data. Beyond the items listed here, CBC data has been used by U.S. federal agencies as an important basis for making decisions about birds. We have classified the papers into categories to give a sense of what you might find when reading the paper.   The population dynamics for genotypes 1, 3 and 4 were analyzed using skyline plots. Bayesian analysis showed that the most recent common ancestor for modern HEV existed between and years by:

      Analysis of population dynamics revealed that coronavirus populations in bats have constant population growth, while viruses from all other hosts show epidemic-like increases in population. These results indicate that diverse coronaviruses are endemic in different bat species, with repeated introductions to other animals and occasional Cited by: Introduction and naturalization of non-native species is one of the most important threats to global biodiversity. Birds have been widely introduced worldwide, but their impacts on populations, communities, and ecosystems have not received as much attention as those of other groups. This work is a global synthesis of the impact of nonnative birds on native ecosystems to determine (1) what Cited by:

An analysis of the population dynamics of selected avian species;: With special reference to changes during the modern pesticide era, (Wildlife research report) Unknown Binding – January 1, by Charles J Henny (Author)Author: Charles J Henny.

The impact of pesticides on the mortality rates and recruitment rates of nongame birds during the last 25 years was evaluated by studying the population dynamics of 16 species. A mathematical model showing the relations between population parameters that yielded stable populations was developed.

The information needed for the model included (1) mortality rate schedule (obtained from recoveries.

The impact that pesticides may have had on the mortality rates and productivity rates of non-game birds during the last 25 years was evaluated by studying the population dynamics of 16 species. A mathematical model showing the relationships between population parameters that yielded stable populations was by: Climate Influences on Avian Population Dynamics Article in Advances in Ecological Research December with Reads How we measure 'reads'.

Random fluctuations in population dynamics are fundamentally important in pure and applied ecology. This book introduces demographic and environmental stochasticity, and illustrates statistical.

Avian immunology is a growing field of study that offers exciting prospects and still has much to contribute to mainstream immunology. Select Chapter 2 - Structure of the Avian Lymphoid System in an ecological context has found that MHC diversity correlates with disease dynamics in several free-living bird species.

Development of the immune. The predominantly urban boroughs of Warrington and Halton straddle the river Mersey in northwest England. Since the s there has been a major change in land-use associated with both innovative town design and the decline of manufacturing and chemical industries in the boroughs.

The first involves long-term studies of population dynamics: recording population size, birth rates, death rates and relevant environmental data and then analysing the data using techniques such as key-factor analysis.
