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.

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 […]
The role of history vs. demography inshaping genetic population structureacross an ecotone: chukar partridges(Alectoris chukar) as a case study
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 […]
Relationship between heterozygosity and asymmetry: a test across the distribution range
Chukar Partridge (Alectoris chukar) Science Article 5 abstract The genetic basis of developmental stability, as measured by bilateral asymmetry, has been debatedfor over 50 years among developmental and evolutionary biologists. One of the central theoriesdealing with this relationship suggests that higher levels of genetic diversity, as re
Spacing of adult and subadult male Common Capercaillie during the breeding season
Capercaillie (Tetrao urogallus) Science Article 2 abstract The spacing behavior of 58 male Common Capercaillie (Tetrao urogaIlus) was studied at Varaldskogen in southeast Norway during 1979-1985. Birds captured at leks were equipped with radio-transmitters, and their movements were monitored throughout the year. During spring, males 4 yr old and older occupied exclusive day territories of […]
Phylogeography of the European capercaillie (Tetrao urogallus ) and its implications for conservation
Capercaillie (Tetrao urogallus) Science Article 11 abstract The phylogeographic pattern of mitochondrial DNA variation in capercaillie (Tetrao urogallus) from 14 populations across the European range was examined using sequence variation in the central portion of the control region and the cytochrome B gene. Twenty-nine different haplotypes were resolved, which formed two distinct phylogenetic clades. The […]
Habitat features of the capercaillie (Tetrao urogallus) leks in the West Carpathians
Capercaillie (Tetrao urogallus) Science Article 4 abstract Habitat characteristics of 43 capercaillie (Tetrao urogallus) leks were studied in the mountains of Central Slovakia (West Carpathians) in 1984-2002. Macro-habitat was described with respect to topography and succession stage. Micro-habitat was described with respect to forest type and forest stand structure. Twenty-seven out of forty-three display grounds […]
Intestinal parasites in the Cantabrian Capercaillie, Tetrao urogallus cantabricus: a coprological study.
Capercaillie (Tetrao urogallus) Science Article 8 abstract The intestinal parasites of the Cantabrian Capercaillie were Estudied by counting the eggs of parasitic species found in 154 f cal samples from 34 localities in the Cantabrian mountains. Prevalence was 58% for Eimeria sp. and 25% for Capillaria sp.; however, both intensity and mean intensity of these […]
Diet of the Cantabrian Capercaillie: geographic variation and energetic content
Capercaillie (Tetrao urogallus) Science Article 7 abstract The diet of the Cantabrian Capercaillie Tetrao urogallus cantabricus was examined by fecal analysis. Droppings were sampled from April 1998 to May 1999 around 23 leks that were grouped in five zones. Winter diet consisted of beech buds, pine needles, buds and catkins of birch and holly leaves. […]
From connectivity to isolation: genetic consequences of population fragmentation in capercaillie across Europe
Capercaillie (Tetrao urogallus) Science Article 3 abstract The capercaillie inhabits a continuous range in large parts of the Palearctic boreal forest, but is patchily distributed in temperate Europe. An ongoing population decline, largely related to human land use changes, has been most pronounced in central and western Europe, where some local populations have become extinct. […]
