Human ecology in the context of "Human biology"

Human behavioral ecology (HBE) or human evolutionary ecology applies the principles of evolutionary theory and optimization to the study of human behavioral and cultural diversity. HBE examines the adaptive design of traits, behaviors, and life histories of humans in an ecological context. One aim of modern human behavioral ecology is to determine how ecological and social factors influence and shape behavioral flexibility within and between human populations. Among other things, HBE attempts to explain variation in human behavior as adaptive solutions to the competing life-history demands of growth, development, reproduction, parental care, and mate acquisition. HBE overlaps with evolutionary psychology, human or cultural ecology, and decision theory. It is most prominent in disciplines such as anthropology and psychology where human evolution is considered relevant for a holistic understanding of human behavior.

Socioecology is the scientific study of how social structure and organization are influenced by an organism's environment. Socioecology is primarily related to anthropology, geography, sociology, and ecology. Specifically, the term is used in human ecology, the study of the interaction between humans and their environment. Socioecological models of human health examine the interaction of many factors, ranging from narrowest (individual behaviors) to broadest (federal policies). The factors of socioecological models consist of individual behaviors, sociodemographic factors (race, education, socioeconomic status), interpersonal factors (romantic, family, and coworker relationships), community factors (physical and social environment), and societal factors (local, state, and federal policies.

A coupled human–environment system (known also as a coupled human and natural system, or CHANS) characterizes the dynamical two-way interactions between human systems (e.g., economic, social, cultural) and natural (e.g., hydrologic, atmospheric, biological, geological) systems. This coupling expresses the idea that the evolution of humans and environmental systems may no longer be treated as individual isolated systems. The complexity that CHANS research reveals is useful to inform policy decisions regarding environmental sustainability.

CHANS research is a broad field. Some research programs draw from, and build on, the perspectives developed in trans-disciplinary fields such as human ecology, ecological anthropology, environmental geography, economics, as well as others. In contrast, other research programs, such as Critical Zone science, aim to develop a more quantitative theoretic framework focusing on the development of analytical and numerical models, by building on theoretical advances in complex adaptive systems, complexity economics, dynamical systems theory, and the earth sciences. To some extent, all CHANS programs recognize the need to move beyond traditional research methods developed in the social and natural sciences, as these are not sufficient to quantify the highly nonlinear dynamics often present in CHANS. Some research into CHANS emulates the more traditional research programs that tended to separate the social from the ecological sciences.

William Robert Catton Jr. (January 15, 1926 – January 5, 2015) was an American sociologist known for his scholarly work in environmental sociology and human ecology. More broadly, Catton is known for his 1980 book, Overshoot: The Ecological Basis of Revolutionary Change, which is credited by younger generations of environmental scholars and activists as foundational for their own works in calling attention to humanity's role in expanding ecological overshoot to the global level.

Robert Ezra Park (February 14, 1864 – February 7, 1944) was an American urban sociologist who is considered to be one of the most influential figures in early U.S. sociology. Park was a pioneer in the field of sociology, changing it from a passive philosophical discipline to an active discipline rooted in the study of human behavior. He made significant contributions to the study of urban communities, race relations and the development of empirically grounded research methods, most notably participant observation in the field of criminology. From 1905 to 1914, Park worked with Booker T. Washington at the Tuskegee Institute. After Tuskegee, he taught at the University of Chicago from 1914 to 1933, where he played a leading role in the development of the Chicago School of sociology.

Park is noted for his work in human ecology, race relations, human migration, cultural assimilation, social movements, and social disorganization He played a large role in defining sociology as a natural science and challenged the belief that sociology is a moral science. He saw sociology as "...a point of view and a method for investigating the processes by which individuals are inducted into and induced to cooperate in some sort of permanent corporate existence, society."
