Chukar Partridge (Alectoris chukar) Science Article 7 abstract Recent advances in molecular ecology allow better assessment of the role of ecologicaland evolutionary processes in determining the dynamics of genetic diversity in naturalpopulations. The chukar partridge (Alectoris chukar) is abundant and continuouslydistributed in the mesic Mediterranean regions of Israel, becoming scarce and patchilydistributed in the arid […]
aerodynamics of wing-assisted incline running in birds
Chukar Partridge (Alectoris chukar) Science Article 6 abstract Wing-assisted incline running (WAIR) is a form oflocomotion in which a bird flaps its wings to aid itshindlimbs in climbing a slope. WAIR is used for escape inground birds, and the ontogeny of this behavior inprecocial birds has been suggested to represent a modelanalogous to transitional adaptive […]
Global warming, Bergmann’s rule and body mass
Chukar Partridge (Alectoris chukar) Science Article 3 abstract Using museum specimens collected in Israel during the second half of the 20th century, no support wasfound for the hypothesis that body mass and tarsus length of chukar partridges Alectoris chukar haschanged as a result of global warming.

A Study on Determining Protein Level in Diet of Partridge (Alectoris chukar)During Growing Period (0-4 Wk)
Chukar Partridge (Alectoris chukar) Science Article 8 abstract This study was conducted to determine growth performance of partridge (A. chukar) fed by dietsinclude different level of CP through 0-4 weeks of age. First, second, third and fourth groups had 28, 26, 24and 22 % CP in diet, respectively. Turgay Oengul et al, International Journal of […]
Hybridisation with introduced chukars (Alectorischukar) threatens the gene pool integrity of native rock(A. graeca) and red-legged (A. rufa) partridge populations
Chukar Partridge (Alectoris chukar) Science Article 10 abstract The decline of over-hunted red-legged (Alectoris rufa) and rock (A. graeca) partridge populationshas been contrasted with massive releases of captive-reared birds, often hybrids withnon-indigenous A. chukar. Released interspecific hybrids raise the risks of introgressivehybridisation, and can contribute to further depress the fitness of native populations Marina Barilani, […]
ECOLOGICAL INVESTIGATIONS OF CHUKARS (ALECTORIS CHUKAR) IN WESTERN UTAH

Identifying the demographic determinants of population growth rate: a case study of red-billed choughs Pyrrhocorax pyrrhocorax
Chough (Pyrrhocorax pyrrhocorax) Science Article 3 abstract Identifying which age-specific demographic rates underlie variation in a population’s growth rate (?) is an important step towards understanding the population’s dynamics. Using data from a 20-year study of marked individuals, we describe patterns of demographic variation and covariation in the Scottish red-billed chough population (Pyrrhocorax pyrrhocorax), and […]
Demographic consequences of prey availabilityand diet of Red-billed Choughs Pyrrhocoraxpyrrhocorax
Chough (Pyrrhocorax pyrrhocorax) Science Article 6 abstract Capsule Variation in prey availability appears to influence Chough fledging success and juvenile survival. Aims To determine seasonal and annual variations in Chough prey and how these influence fledging success and juvenile survival.

Environmental variability, life-history covariation and cohort effects in the red-billed chough Pyrrhocorax pyrrhocorax
Chough (Pyrrhocorax pyrrhocorax) Science Article 4 abstract The consequences of environmental variability for life-history evolution are predicted to depend on the pattern of covariation amongst life-history traits. Using data from a 20-year study of individually marked red-billed choughs, we investigate the short- and long-term life-history consequences of population-wide variation in reproductive conditions, and demonstrate clear […]
