“…Pygmy field mice are described as the least aggressive member of the Apodemus family (Suchomelova and Frynta, 2000) with extensive allogrooming (Stopka and Graciasova, 2001). Long-tailed wood mice form family groups with several females and one male, whereas the biggest Apodemus species, yellow-necked wood mice behave rather aggressive toward conspecifics (Niethammer and Krapp, 1978).…”

Daily life of wild mammals is characterized by a multitude of attractive and aversive stimuli. The hippocampus processes complex polymodal information associated with such stimuli and mediates adequate behavioral responses. How newly generated hippocampal neurons in wild animals contribute to hippocampal function is still a subject of debate. Here, we test the relationship between adult hippocampal neurogenesis (AHN) and habitat types. To this end, we compare wild Muridae species of southern Africa [Namaqua rock mouse (Micaelamys namaquensis), red veld rat (Aethomys chrysophilus), highveld gerbil (Tatera brantsii), and spiny mouse (Acomys spinosissimus)] with data from wild European Muridae [long-tailed wood mice (Apodemus sylvaticus), pygmy field mice (Apodemus microps), yellow-necked wood mice (Apodemus flavicollis), and house mice (Mus musculus domesticus)] from previous studies. The pattern of neurogenesis, expressed in normalized numbers of Ki67- and Doublecortin(DCX)-positive cells to total granule cells (GCs), is similar for the species from a southern African habitat. However, we found low proliferation, but high neuronal differentiation in rodents from the southern African habitat compared to rodents from the European environment. Within the African rodents, we observe additional regulatory and morphological traits in the hippocampus. Namaqua rock mice with previous pregnancies showed lower AHN compared to males and nulliparous females. The phylogenetically closely related species (Namaqua rock mouse and red veld rat) show a CA4, which is not usually observed in murine rodents. The specific features of the southern environment that may be associated with the high number of young neurons in African rodents still remain to be elucidated. This study provides the first evidence that a habitat can shape adult neurogenesis in rodents across phylogenetic groups.

“…Lambin (1988) reported that during monitoring of feeding arena, no fighting between adult males was recorded, but adult males behaved agonistic towards subadults. In a closely related species, A. microps, social encounters between males can be substantially affected by the home cage design and males become more agonistic when compared to previous neutral cage conditions (Suchomelová and Frynta 2000).…”

Social relations in family-groups of wood miceApodemus sylvaticus under laboratory and enclosure conditions. Acta Theriologica 47: 151-162.Two family-groups of wood mice Apodemus sylvaticus (Linnaeus, 1758) were observed: one in the laboratory (terrarium 100 ´ 60 ´ 60 cm) and the other under enclosure conditions (outdoor enclosure 200 ´ 100 ´ 100 cm). Three consecutive periods in the social relations of the family-groups were described: the linear hierarchy, the multidirectional social relations, and the variable dominance-subordination relations. The linear social hierarchy was reflected in the subordination behaviour of family members in relation to the dominant male, the father of the family. During the period of coexistence of a pair of parents with two litters of juveniles, both in the laboratory and under enclosure conditions, amicable relations between individuals occurred. Advanced forms of social care (paternal care, allomaternal lactation, transportation and licking by relatives) were also observed. In the laboratory, agonistic interactions were lacking during the linear hierarchy period, but the attainment of sexual maturity by individuals of the first two litters, accompanied by an increase in the number of mice, resulted in aggression between mature males and competition for dominance. Further, under increasingly crowded conditions, agonistic behaviour prevailed over other types of social interaction, and the survival rate of juveniles decreased. Under enclosure conditions a seasonal variation in agonistic interaction between mature individuals was recorded, similar to that observed in the wild. Despite the systematic increase in population density, no attacks by mature males on juveniles were observed.
