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]

In reviewing the older leadership theories, Scouller highlighted certain limitations in relation to the development of a leader's skill and effectiveness: [3] Trait theory: As Stogdill (1948) [4] and Buchanan & Huczynski (1997) had previously pointed out, this approach has failed to develop a universally agreed list of leadership qualities and "successful leaders seem to defy classification ...
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.
If occasionally associating or nesting with other adults is a taxon's most social behaviour, then members of those populations are said to be solitary but social. See Wilson (1971) [9] for definitions and further sub-classes of varieties of subsociality. Choe & Crespi (1997) [11] and Costa (2006) [12] give readable overviews.
Behavior (American English) or behaviour (British English) is the range of actions and mannerisms made by individuals, organisms, systems or artificial entities in some environment. These systems can include other systems or organisms as well as the inanimate physical environment.
Another advantage of group living is an increased ability to forage for food. Group members may exchange information about food sources, facilitating the process of resource location. [10] [page needed] Honeybees are a notable example of this, using the waggle dance to communicate the location of flowers to the rest of their hive. [45]
The black walnut secretes a chemical from its roots that harms neighboring plants, an example of competitive antagonism.. In ecology, a biological interaction is the effect that a pair of organisms living together in a community have on each other.
