Heterogeneity can be defined as the difference or diversity in kind or arrangement of component elements or constituents. Multiple conceptualizations, definitions, and operationalizations of heterogeneity allow for the investigation of different aspects of ecological patterns on different ecological processes.

Secondly, what is temporal heterogeneity? 1 Usually, temporal issues are examined in relation to ecological succession, and temporal heterogeneity is defined in conjunction with physical disturbance. 2 We use temporal heterogeneity to describe the entire complex of interactions between abiotic and biotic factors that relate time and resource use.

Keeping this in view, what is Habitat heterogeneity definition?

habitat heterogeneity. (noun) variation in physical environmental features within an area, such as topography, soil chemistry, temperature, moisture, and biological factors.

What is structural heterogeneity?

Structural heterogeneity. The structuralist theory of development seeks to explain why some regions lag behind in terms of per capita income and why this lag is accompanied by a sharp inequalities in distribution, both within the lagging region and within countries.

Is heterogeneity good or bad?

Heterogeneity and its opposite, homogeneity, refer to how consistent or stable a particular data set or variable relationship are. Having statistical heterogeneity is not a good or bad thing in and of itself for the analysis; however, it's useful to know to design, choose and interpret statistical analyses.

Why is heterogeneity important?

Reasons for heterogeneity, other than clinical differences, could include methodological issues such as problems with randomisation, early termination of trials, use of absolute rather than relative measures of risk, and publication bias. A high percentage, such as the 80% seen here, suggests important heterogeneity.

What is another word for heterogeneity?

What does heterogeneity mean in medical terms?

Heterogeneous medical condition or heterogeneous disease in medicine are those medical conditions which have several etiologies, like hepatitis or diabetes. The word is used as an opposition to homogeneous, meaning that given a group of patients, the disease is the same for all of them.

What does heterogeneity mean in research?

Heterogeneity in statistics means that your populations, samples or results are different. It is the opposite of homogeneity, which means that the population/data/results are the same. A heterogeneous population or sample is one where every member has a different value for the characteristic you're interested in.

What does heterogeneity in a study mean?

Heterogeneity in meta-analysis refers to the variation in study outcomes between studies. The I² statistic describes the percentage of variation across studies that is due to heterogeneity rather than chance (Higgins and Thompson, 2002; Higgins et al., 2003).

What is heterogeneity in biology?

Freebase. Genetic heterogeneity. Genetic Heterogeneity is a phenomenon in which a single phenotype or genetic disorder may be caused by any one of a multiple number of alleles or non-allele mutations. This is in contrast to pleiotropy, where a single gene may cause multiple phenotypic expressions or disorders.

What does high heterogeneity mean?

Heterogeneity is not something to be afraid of, it just means that there is variability in your data. The opposite of heterogeneity is homogeneity meaning that all studies show the same effect.

What is the effect of spatial heterogeneity?

However the increasing of habitat heterogeneity leads to the reduction of the area of each distinct region of the entire habitat. Consequently, the population sizes of the species shrink, in such a way that species become more vulnerable to stochastic extinctions.

What does heterogeneous mean in geography?

composed of parts of different kinds; having widely dissimilar elements or constituents: The party was attended by a heterogeneous group of artists, politicians, and social climbers. Chemistry. (of a mixture) composed of different substances or the same substance in different phases, as solid ice and liquid water.

What is scale in ecology?

In spatial ecology, scale refers to the spatial extent of ecological processes and the spatial interpretation of the data. The response of an organism or a species to the environment is particular to a specific scale, and may respond differently at a larger or smaller scale.

Does heterogeneous mean cancer?

Cancer is a heterogeneous disease. However, heterogeneity in cancer is not limited to differences between different patients, but also occurs within a single patient (Figure 1). This intrapatient or intratumoral heterogeneity can present great challenges for cancer treatment.

What is a heterogeneous appearance?

Heterogeneous refers to a structure with dissimilar components or elements, appearing irregular or variegated. For example, a dermoid cyst has heterogeneous attenuation on CT. It is the antonym for homogeneous, meaning a structure with similar components. Heterogenous refers to a structure having a foreign origin.

What are heterogeneous materials?

Definition of heterogeneous materials
Heterogeneous materials can be defined as materials with dramatic heterogeneity in strength from one domain area to another. This strength heterogeneity can be caused by microstructural heterogeneity, crystal structure heterogeneity or compositional heterogeneity.
