TERRITORIAL STRUCTURE AND SOCIAL ORGANIZATION OF TWO SUBSPECIES OF THE MIDDAY GERBIL (MERIONES MERIDIANUS NOGAIORUM, M. M. PSAMMOPHILUS) (MURIDAE, MAMMALIA) UNDER SEMI-NATURAL CONDITIONS

The territorial structure and social organization of artificial groups of two subspecies of the midday gerbil (Meriones meridianus nogaiorum, M. m. psammophilus) were studied under semi-natural conditions. No significant differences in the space usage system of the subspecies under comparison were found. The structure of social interactions was found to be identical in females but different in males: M. m. nogaiorum males exhibited dominance hierarchy, whilst a despotic dominance was found in M. m. psammophilus males. M. m. psammophilus females also exhibited dominance hierarchy.

BREEDING BIOLOGY AND SOCIAL ORGANIZATION OF EASTERN SIBERIAN STONECHAT - SAXICOLA (TORQUATUS) STEJNEGERI (PARROT, 1908) (MUSCICAPIDAE, AVES)

The breeding biology and social organization of a population of the Eastern Siberian stonechat were studied in the Khingan State Nature Reserve (Amur region, Russia) in 2013. This is a territorial monogamy species, inhabiting various types of open areas and nesting on the ground. The Eastern Siberian stonechat belongs to the Common stonechat complex comprising 3 or 4 sibling species.
