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]
The trematodes are a class of parasitic flatworm, also known as flukes. One species, Haplorchis pumilio, has evolved eusociality involving a colony creating a class of sterile soldiers. [39] One fluke invades a host and establishes a colony of dozens to thousands of clones that work together to take it over.
Behavioral ecology, also spelled behavioural ecology, is the study of the evolutionary basis for animal behavior due to ecological pressures. Behavioral ecology emerged from ethology after Niko Tinbergen outlined four questions to address when studying animal behaviors: What are the proximate causes, ontogeny, survival value, and phylogeny of a behavior?
Heralded as the world's largest rodents, the South American rainforest natives can actually weigh as much as a full grown man.. But despite the fact that they apparently like to eat their own dung ...
In hydra, a bud develops as an outgrowth due to repeated cell division at one specific site. These buds develop into tiny individuals and, when fully mature, detach from the parent body and become new independent individuals. Internal budding or endodyogeny is a process of asexual reproduction, favored by parasites such as Toxoplasma gondii. It ...
In warm blooded animals (mammals and birds) this state is referred to as hibernation or torpor (shorter periods of inactivity between awakening); whereas a similar condition in cold-blooded ...
Synchronous behavior is also threatened when animals in a mixed-sex herd have differing nutritional or physical necessities. This causes group instability which often splits the herd up into two separate groups; generally all male and all female, to recreate the mimetic behavior in a smaller, same-sex group that has more similar needs to the individual.

Opportunity providing is a social learning mechanism in which the experienced individual puts the observer in a situation that facilitates the acquisition of knowledge or a new skill. [1] A well known example of unintentional opportunity providing is the transmission of feeding behavior in black rats (Rattus rattus). One pilot study determined ...
