What is ecotype in biology?

An ecotype is a population (or subspecies or race) that is adapted to local environmental conditions. Thus, the adaptations of these ecotypes are based on the interactions of their own special sets of genes with their own environment.

What is ecotype and its example?

Definition. An ecotype is a variant in which the phenotypic differences are too few or too subtle to warrant being classified as a subspecies. These different variants can occur in the same geographic region where distinct habitats such as meadow, forest, swamp, and sand dunes provide ecological niches.

What is ecotype in zoology?

ecotype A locally adapted population of a widespread species. Such populations show minor changes of morphology and/or physiology, which are related to habitat and are genetically induced. Nevertheless they can still reproduce with other ecotypes of the same species. A Dictionary of Zoology MICHAEL ALLABY.

What is the difference between ecotype and species?

As nouns the difference between species and ecotype is that species is a type or kind of thing while ecotype is (ecology) a group of organisms, normally a subdivision of a species, that is adapted to a specific environment.

What is Cenospecies?

cenospecies. / (ˈsiːnəˌspiːʃiːz) / noun plural -species. a species related to another by the ability to interbreeddogs and wolves are cenospecies.

What is Ecotone in biology?

Ecotones are areas of steep transition between ecological communities, ecosystems, and/or ecological regions along an environmental or other gradient. Ecotones occur at multiple spatial scales and range from natural ecotones between ecosystems and biomes to human-generated boundaries.

What are Ecads?

An ecad is a type of plant that has evolved to live in a very distinct area. When the seeds of a plant that has only ever grown in the open expanse and sunshine-laden fields are transplanted to the shade of a forest and they produce plants then the plants are called ecads. Such a plant becomes known as an ecad.

What is difference between ecotype and Ecophene?

The key difference between ecotype and ecophene is that ecotype shows permanence in the adaptation due to the changes in genes, while ecophene shows temporary variations to survive in new conditions, and there are no changes in genes.

What does Ecocline mean?

: a series of intergrading forms produced within a group in a zone of intergradation between two distinctive ecological niches — compare genocline.

What is meant by Ecophene?

Ecophene. (Science: genetics) The variety of phenotypes (visible physical characteristics or behaviours), from a single genotype (a specific combinations of alleles in a gene), that can be observed in a population within a particular habitat.

What do you mean by sibling species?

34) defines sibling species as morphologically similar or identical populations which are reproductively isolated. Entomologists tend to restrict the term to those groups of species which are morphologically identical, or nearly so.

What is an ecotone example?

An ecotone is an area that acts as a boundary or a transition between two ecosystems. Examples of ecotones include marshlands (between dry and wet ecosystems), mangrove forests (between terrestrial and marine ecosystems), grasslands (between desert and forest), and estuaries (between saltwater and freshwater).

Which is the best definition of an ecotype?

Definition of ecotype. : a population of a species that survives as a distinct group through environmental selection and isolation and that is comparable with a taxonomic subspecies.

Can an ecotype interbreed with Another ecotype?

Typically, though ecotypes exhibit phenotypic differences (such as in morphology or physiology) stemming from environmental heterogeneity, they are capable of interbreeding with other geographically adjacent ecotypes without loss of fertility or vigor.

How are ecotypes and morphs related in evolutionary biology?

Ecotypes are closely related to morphs. In the context of evolutionary biology, genetic polymorphism is the occurrence in the equilibrium of two or more distinctly different phenotypes within a population of a species, in other words, the occurrence of more than one form or morph.

How are ecovars used to study ecotypes?

Therefore, we used several genomic methods, e.g. direct whole genome comparison, digital DNA–DNA hybridization and microarray-based comparative genomic hybridization (MCGH) as complementary approaches to justify that these ecovars represent two distinct subspecies. These methods will be described in more detail in the course of this chapter.
