Spread of Avian Influenza Viruses by Common Teal (Anas crecca) in Europe
Since the recent spread of highly pathogenic (HP) H5N1 subtypes, avian influenza virus (AIV) dispersal has become an increasing focus of research. As for any other bird-borne pathogen, dispersal of these viruses is related to local and migratory movements of their hosts. In this study, we investigated potential AIV spread by Common Teal (Anas crecca) from the Camargue area, in the South of Fran...
متن کاملA flyway perspective of foraging activity in Eurasian Green-winged Teal, Anas crecca crecca
Time–activity budgets in the family Anatidae are available for the wintering and breeding periods. We present the first flyway-level study of foraging time in a long-distance migrant, the Eurasian Green-winged Teal, Anas crecca crecca L., 1758 (‘‘Teal’’). Behavioral data from early and late spring staging, breeding, and molting sites were collected with standardized protocols to explore differe...
متن کاملA parapatric propensity for breeding precludes the completion of speciation in common teal (Anas crecca, sensu lato).
Speciation is a process in which genetic drift and selection cause divergence over time. However, there is no rule dictating the time required for speciation, and even low levels of gene flow hinder divergence, so that taxa may be poised at the threshold of speciation for long periods of evolutionary time. We sequenced mitochondrial DNA (mtDNA) and eight nuclear introns (nuDNA) to estimate geno...

متن کاملRisk Assessment of the Introduction and Spread of Highly Pathogenic Avian Influenza Viruses (H5-Subtypes) Via Migratory Birds in Iran
Background and Objectives: HPAI has economic and public health importance. Aquatic and shore migratory birds are the main reservoirs and the cause of the spread of viruses across countries. The aim of study was risk assessment of the spread of the avian influenza H5 viruses. Methods: In this qualitative study, structured interviews and focus group discussions were used to assess the risk of...
