Using an appropriate Southern California example: ethno refers to a particular socio-cultural group (for example, a particular, local community of surfers); method refers to the methods and practices this particular group employs in its everyday activities (for example, related to surfing); and ology refers to the systematic description of ...
Humans, for example, can represent a keystone species in a given ecosystem and can play critical roles in creating, maintaining, and sustaining it . They can contribute to processes such as pedogenesis, seed dispersal, and fluctuations in biodiversity. [12] They can also modify and condition animal behavior in either wild or domesticated ...
Logo for the Society of Ethnobiology. Ethnobiology is the multidisciplinary field of study of relationships among peoples, biota, and environments integrating many perspectives, from the social, biological, and medical sciences; along with application to conservation and sustainable development.
One example of such work is ethnobiology which employs Indigenous knowledge and botany to identify and classify species. [30] TEK has been used to provide perspectives on matters such as how a declining fish population affects nature, the food web, and coastal ecosystems. [31]
Ecotypes are closely related to morphs or polymorphisms which is defined as the existence of distinct phenotypes among members of the same species. [16] Another term closely related is genetic polymorphism; and it is when species of the same population display variation in a specific DNA sequence, i.e. as a result of having more than one allele ...
Polyphagy is the habit in an animal species, of eating and tolerating a relatively wide variety of foods, whereas monophagy is the intolerance of every food except for one specific type (see generalist and specialist species). Oligophagy is a term for intermediate degrees of selectivity, referring to animals that eat a relatively small range of ...
The yellow mask is a plesiomorphy for each living masked species, because it is ancestral. [2] It is also a symplesiomorphy for them. But for the four living species as a whole, it is an apomorphy because it is not ancestral for all of them. The yellow tail is a plesiomorphy and symplesiomorphy for all living species.
Ethnoichthyology is a multidisciplinary field of study that examines human knowledge of fish, the uses of fish, and importance of fish in different human societies.It draws on knowledge from many different areas including anthropology, ichthyology, economics, oceanography, and marine botany.
