Shimmering behaviour of Apis dorsata (giant honeybees). A group of animals fleeing from a predator shows the nature of herd behavior, for example in 1971, in the oft-cited article "Geometry for the Selfish Herd", evolutionary biologist W. D. Hamilton asserted that each individual group member reduces the danger to itself by moving as close as possible to the center of the fleeing group.
Three cleavage-based voting factors, or individual differences impacting voting behavior, focused on in existing research are religion, class, and gender. [12] In recent years, voting cleavage has shifted from concerns of Protestant vs Catholic religions to have a larger focus on religious vs non-religious leanings. [12]
Some abnormal behaviours may be related to environmental conditions (e.g. captive housing) whereas others may be due to medical conditions. The list does not include behaviours in animals that are genetically modified to express abnormal behaviour (e.g. reeler mice). A polar bear performing stereotyped pacing.
Animal welfare advocates push for enforced standards to ensure the health and safety of those animals used for tests. In the US, every institution that uses vertebrate animals for federally funded laboratory research must have an Institutional Animal Care and Use Committee (IACUC). [ 91 ]
Evidence for animal culture is often based on studies of feeding behaviors, [8] vocalizations, [4] predator avoidance, [9] mate selection, [10] and migratory routes. [11] An important area of study for animal culture is vocal learning, the ability to make new sounds through imitation. [4] Most species cannot learn to imitate sounds.
The idea of swarm robots has been around for some time but researchers are now looking more closely at nature for robot design inspiration.
Agonistic behaviour is a result of evolution, [5] and this can be studied in a number of species facing different environmental pressures. Though agonistic behaviours can be directly observed and studied in a laboratory setting, it is also important to understand these behaviours in a natural setting to fully comprehend how they have evolved and therefore differ under different selective ...
