A zebra harem within a herd. The plains zebra is highly social and usually forms small family groups called harems, which consist of a single stallion, several mares and their recent offspring. The adult membership of a harem is highly stable, typically remaining together for months to years.
A plains zebra group . Zebra species have two basic social structures. Plains and mountain zebras live in stable, closed family groups or harems consisting of one stallion, several mares, and their offspring. These groups have their own home ranges, which overlap, and they tend to be nomadic. Stallions form and expand their harems by herding ...
Sociobiology investigates social behaviors such as mating patterns, territorial fights, pack hunting, and the hive society of social insects. It argues that just as selection pressure led to animals evolving useful ways of interacting with the natural environment, so also it led to the genetic evolution of advantageous social behavior. [4]
Plains zebra groups gather into large herds and may create temporarily stable subgroups within a herd, allowing individuals to interact with those outside their group. Among harem-holding species, this behavior has only otherwise been observed in primates such as the gelada and the hamadryas baboon. Females of harem species benefit as males ...
The modern Grévy's zebra arose in the Middle Pleistocene. [9] Zebras appear to be a monophyletic lineage [10] [11] [12] and recent (2013) phylogenies have placed Grévy's zebra in a sister taxon with the plains zebra. [10] In areas where Grévy's zebras are sympatric with plains zebras, the two may gather in same herds [13] and fertile hybrids ...
Social learners' fitness decreases as their frequency increases. Social learning does not necessarily mean that the transmitted behavior is the most efficient response to a stimulus. If a socially learned behavior expends unnecessary energy, and there is a more efficient strategy that is not being utilized, employing social learning is maladaptive.
Chapman's zebra are native to savannas and similar habitats of north-east South Africa, north to Zimbabwe, west into Botswana, the Caprivi Strip in Namibia, and southern Angola. [4] Like the other subspecies of plains zebra, it is a herbivore that exists largely on a diet of grasses, and undertakes a migration during the wet season to find ...
Collective animal behaviour is a form of social behavior involving the coordinated behavior of large groups of similar animals as well as emergent properties of these groups. This can include the costs and benefits of group membership, the transfer of information, decision-making process, locomotion and synchronization of the group.
