Local equilibrium in bird flocks

The correlated motion of flocks is an instance of global order emerging from local interactions. An essential difference with analogous ferromagnetic systems is that flocks are active: animals move relative to each other, dynamically rearranging their interaction network. The effect of this off-equilibrium element is well studied theoretically, but its impact on actual biological groups deserve...

Bird Mite Infestation

Mites in the genus Dermanyssus are external parasites of birds, rodents and other mammals. The most common member of this group is the Chicken Mite that infests poultry roosts and wild bird nests. The chicken mite feeds primarily at night when the birds return the nest or roast area. They hide during the day in nearby cracks, crevices and other protected sites. These mites are known to infest h...

Molecular detection and phylogenetic analysis of Avipoxvirus strains isolated from different bird species

The polymerase chain reaction (PCR) was used to amplify a 578 bp fragment of the poxvirus 4b core protein. Avipoxvirus (APV) specific DNA was detected in all 10 different isolates (each of which had been isolated from an epidemic) isolated from chicken; canary and mynah were collected from Tehran province. Sequencing was performed for 2 isolates as representative and the nucleotide sequence sho...

Overview — A Bird ’ s - Eye View of the Poster Papers

The hardwood industry in California is not well documented and often is described as fragmented. An analysis of hardwood interests in the state reveals a wide gap between hardwood consumption and the supply of native hardwood lumber. A recent survey of individuals, companies, and agencies involved in hardwood utilization provides the data for profiling the hardwood industry. A questionnaire mai...
