1. We examine harvesting records of rock partridge (Alectoris graeca saxatilis) to first identify the presence of cycles in a species with a southern European distribution and then examine synchrony between populations at a range of scales. 2. Hunting records from 1965 to 1994 were obtained from 210 hunting areas and analysed at three spatial scales: sub-population, population and metapopulatio...

Carotenoids are important for various functions during chick development. Since these pigments cannot be synthesized, they can be considered limited resources that the mother optimally allocates between herself and her offspring (maternal effect). Some studies have examined the effects of carotenoids on growth and immune function but little is known about their role in behaviour. In this study ...

Understanding the historical dynamics of animal species is critical for accurate prediction of their response to climate changes. During the late Quaternary period, Southeast Asia had a larger land area than today due to lower sea levels, and its terrestrial landscape was covered by extensive forests and savanna. To date, however, the distribution fluctuation of vegetation and its impacts on ge...

The purpose of this study was to determine the percentages of alpha-naphthyl acetate esterase (ANAE)-positive and acid phosphatase (ACP)-positive peripheral blood lymphocytes (PBL) and the percentages of leukocytes in the rock partridge at different ages. Blood samples obtained from the vena basilica of 18 healthy rock partridges (Alectoris graeca) at 1 d, 5 wk, and 12 wk of age were used. Mean...
