Egg Production and Some Hatchability Characteristics of RockPartridges (Alectoris graeca) Mated at Different Rates

Rock Partridge (Alectoris graeca) Science Article 2 abstract This study was carried out to determine the hatchability characteristics of rock partridges mated at the ratio of one maleto three females, one male to four females and one male to five females. Egg production/hen (%), fertile eggs/hen, fertility,hatchability and hatchability of fertile eggs of one male […]

Synchrony, scale and temporal dynamics of Rock partridge (Alectoris graeca saxatilis) populations in the Dolomites

Rock Partridge (Alectoris graeca) Science Article 1 abstract 1. We examine harvesting records of rock partridge (Alectoris graeca saxatilis) to first identify thepresence of cycles in a species with a southern European distribution and then examine synchronybetween populations at a range of scales.2. Hunting records from 1965 to 1994 were obtained from 210 hunting areas […]

Mitochondrial DNA sequence variation and phylogeographical structure of rock partridge (Alectoris graeca) populations

Rock Partridge (Alectoris graeca) Science Article 4 abstract The rock partridge (Alectoris graeca) is distributed in the Alps, Apennines and Balkans, in mountainous areas that were heavily affected by cyclic climate and landscape changes during the last Pleistocene glaciations. Some partridge populations have colonized and expanded their present ranges only after deglaciation and recent deforestation […]

Evolutionary and conservation genetics of the rock partridge, Alectoris graeca

Rock Partridge (Alectoris graeca) Science Article 3 abstract Rock partridge (Alectoris graeca) populations are declining throughout their range due to habitat changes and overhunting. Massive restocking with captive-reared hybrid birds may lead to risk of genetic pollution. We sequenced 450 nucleotides from the mitochondrial DNA control-region, and genotyped eight microsatellite loci with the aim of […]

CAUSES AND CONSEQUENCES OF INGESTED LEAD PELLETS IN CHUKARS

Red-legged Partridge (Alectoris rufa) Science Article 4 abstract Lead-pellet ingestion andthe resulting toxicosis are well-documented in waterfowl,raptors, and Mourning Doves (Zenaidamacroura) (Kendall et al. 1996).

Sex- and age-related variation in plasma carotenoids despite a constant diet in the Red-legged Partridge Alectoris rufa

Red-legged Partridge (Alectoris rufa) Science Article 2 abstract We studied seasonal variation in plasma carotenoid levels of captive Redlegged Partridges Alectoris rufa in relation to sex, age and condition. The legs, bill and eye lores in this species are bright red due to carotenoid pigments. Carotenoid levels in the plasma varied significantly among sampling periods. […]

Effects of Housing Type and Breeding System on the Reproductive Capacity of the Red-Legged Partridge (Alectoris rufa)

Red-legged Partridge (Alectoris rufa) Science Article 1 abstract Current methods of intensive breeding of the red-legged partridge (Alectoris rufa) are based on ‘industrial’ laying practices, including removal and artificial incubation of eggs. These procedures can alter the reproductive behavior and physiology of the birds and, therefore, may not be suitable for use in breeding programs […]

Open-habitat birds in recently burned areas: the role of the fire extent and species’ habitat breadth

Red-legged Partridge (Alectoris rufa) Science Article 3 abstract Single burned areas contained 0 to 15 open-habitat species (mean = 7.6), and in all the areas combined there were 22 species, including 17 with an unfavourable conservation status in Europe. The most frequent were Carduelis cannabina, Lullula arborea, Alectoris rufa, Oenanthe hispanica and Emberiza cia, but […]

GENETIC STRUCTURE OF CHUKAR (ALECTORIS CHUKAR) POPULATIONS IN ISRaeL

Chukar Partridge (Alectoris chukar) Science Article 1 abstract We used multilocus proteine lectrophoresis to analyze population genetics of Chukars collected at five locations along a north-south gradient in Israel. These birds belongedto two nominal subspecies, the northern A. c. cypriotes, and southern A. c. sinaica.Chukars from China were used as an outgroup. ETTORE RANDI, The […]
