Helping behavior refers to voluntary actions intended to help the others, with reward regarded or disregarded. It is a type of prosocial behavior (voluntary action intended to help or benefit another individual or group of individuals, such as sharing, comforting, rescuing and helping).
Altruism is distinguished from helping behavior. Altruism refers to prosocial behaviors that are carried out without expectation of obtaining external reward (concrete reward or social reward) or internal reward (self-reward).
Kin selection theory explains altruism in evolutionary perspective. Since natural selection aids in screening out species without abilities to adapt the challenging environment, preservation of good traits and superior genes are important for survival of future generations (i.e. inclusive fitness). Kin selection refers to the tendency to perform behaviors that may favor the chance of survival of people with similar genetic base.
A community is a social unit of any size that shares common values, or that is situated in a given geographical area (e.g. a village or town). It is a group of people who are connected by durable relations that extend beyond immediate genealogical ties, and who mutually define that relationship as important to their social identity and practice. Although communities are usually small, community may also refer to large groups, such as national communities, international communities, and virtual communities.
The word "community" is derived from the Old French comuneté which comes from the Latin communitas (from Latin communis, things held in common).
In human communities, intent, belief, resources, preferences, needs, and risks, may be shared in common, affecting the identity of the participants, and their degree of cohesiveness.
Community studies is an academic field drawing on both sociology and anthropology and the social research methods of ethnography and participant observation in the study of community. In academic settings around the world, community studies is variously a sub-discipline of anthropology or sociology, or an independent discipline. It is often interdisciplinary and geared toward practical applications rather than purely theoretical perspectives. Community studies is sometimes combined with other fields, i.e., "Urban and Community Studies," "Health and Community Studies," or "Family and Community studies."
In ecology, a community or biocoenosis is an assemblage or association of populations of two or more different species occupying the same geographical area and in a particular time. The term community has a variety of uses. In its simplest form it refers to groups of organisms in a specific place or time, for example, "the fish community of Lake Ontario before industrialization".
Community ecology or synecology is the study of the interactions between species in communities on many spatial and temporal scales, including the distribution, structure, abundance, demography, and interactions between coexisting populations. The primary focus of community ecology is on the interactions between populations as determined by specific genotypic and phenotypic characteristics. Community ecology has its origin in European plant sociology. Modern community ecology examines patterns such as variation in species richness, equitability, productivity and food web structure (see community structure); it also examines processes such as predator-prey population dynamics, succession, and community assembly.
