Gründe hierfür sind vor allem im zunehmenden Preiswettbewerb sowie der kontinuierlichen Angleichung der Produktqualitäten auf zahlreichen Märkten zu sehen (Aaker/Joachimsthaler 2000a, S. IX).

Sex-Biased Dispersal and Social Systems of Neotropical Emballonurids (greater sac-winged bat .) or female-defense polygyny (proboscis bat .). However, in the gray sac-winged bat (.) females are the more philopatric sex and the social system involves some sort of sexual segregation with mating probably taking place at male mating aggregations. To conclude, we discuss搜集 发表于 2025-3-27 10:05:39

Acoustic Communication and Group Cohesion in Spix’s Disc-Winged Batsially associate with, group members due to strong individual signatures in these two types of calls; group cohesion may be further facilitated by recognition based on spatial location, as this species uses small roosting home ranges and exhibits extreme philopatry to the natal territory.

Daily and Seasonal Patterns of Singing by the Mexican Free-Tailed Bat, ,y male colonies. In a natural roost, males sang the most just before sunrise, but also sang prolifically just after sunset and sporadically throughout the night. This pattern suggested that singing patterns were driven by the activity of conspecifics leaving and returning to the roost, and also indiBRINK 发表于 2025-3-28 11:13:44
Social Learning and Information Transfer in Bats: Conspecific Influence Regarding Roosts, Calls, andtudies have shown that bats can learn from one another about food type, food location, and other food-related cues. In addition, social information can play a role in roost site selection and the acquisition and modification of vocalizations. Here, I review recent research documenting vocal learning
