Associate Professor of Biology, Pomona College, Claremont, California, 91711. Abstract: Changes in rodent and avian community structure were documented for 42 months following a major fire in southern California chaparral. Rodent species richness, biomass per ha, and diversity reached levels equal to, or exceeding, those in 16 to 20 year old chaparral within 15 to 24 months post-fire. Heteromyi...

effect of ethanol consumption on fear response in human and conventional animal models (rodents) is controversial. the present study aimed to investigate the effect of ethanol administration on fearfulness in poultry as an alternative animal model.being a reliable measure in avian species, tonic immobility was used to evaluate the fear response in 60 roosters orally administered with ethanol. d...

The adaptation of H5N1 avian influenza viruses to human poses a great threat to public health. Previous studies indicate the adaptive mutations in viral polymerase of avian influenza viruses are major contributors in overcoming the host species barrier, with the majority of mammalian adaptive mutations occurring in the PB2 protein. However, the adaptive mutations in the PA protein of the H5N1 a...

Canine influenza is a highly contagious respiratory infection of dogs caused by the Influenza A Virus (IAV), characterized cough, sneeze, nasal secretions, and inappetence. Infections can be mild, severe or fatal. Aquatic birds constitute natural reservoir for IAV, which transmitted to terrestrial birds, including poultry. IAV has also emerged in other mammalian species, humans, swine, horses, ...

T ongoing avian influenza (H5N1) pandemic poses risks to both human and animal health (1–5). The potential exists for cross-species transmission of avian influenza to humans and subsequent reassortment of avian and human influenza viruses in coinfected persons (6). Although atypical presentations of avian influenza (H5N1) have been reported (7,8), in most H5N1 case-patients pneumonia was the pr...

BACKGROUND Avian influenza viruses are known to productively infect a number of mammal species, several of which are commonly found on or near poultry and gamebird farms. While control of rodent species is often used to limit avian influenza virus transmission within and among outbreak sites, few studies have investigated the potential role of these species in outbreak dynamics. METHODOLOGY/P...

a r t i c l e i n f o Avian biodiversity is threatened, and in order to prioritize limited conservation resources and conduct effective conservation planning a better understanding of avian species richness patterns is needed. The use of image texture measures, as a proxy for the spatial structure of land cover and vegetation, has proven useful in explaining patterns of avian abundance and spec...

Position-specific entropy profiles created from scanning 306 human and 95 avian influenza A viral genomes showed that 228 of 4591 amino acid residues yielded significant differences between these 2 viruses. We subsequently used 15,785 protein sequences from the National Center for Biotechnology Information (NCBI) to assess the robustness of these signatures and obtained 52 "species-associated" ...
