abstract bavanat county, with an area of 4992 km², is located in north east of fars province. during a long-term avifauna survey in the area which lasted 8 years (2007-2014), 85 bird species belonging to 12 orders and 32 families, identified and reported. the order passeriformes with 61 species was the most diverse order in the study area. the most diverse families were turdidae, fringillidae a...

Avian locomotor burst performance (e.g. acceleration, maneuverability) decreases with increasing body size and has significant implications for the survivorship, ecology and evolution of birds. However, the underlying mechanism of this scaling relationship has been elusive. The most cited mechanistic hypothesis posits that wingbeat frequency alone limits maximal muscular mass-specific power out...

A meta-analysis approach was used to extract the frequency of avian seropositivity to West Nile Virus (WNV) (fS) and mortality from WNV (fM) from the literature published between the years 2001-2010. The indices, fS and fM, were used to represent states of resistance (seropositivity with no or limited mortality) and susceptibility in birds (detection of WNV with mortality), respectively. The in...
