  2. Biological tests of necessity and sufficiency - Wikipedia

    en.wikipedia.org/wiki/Biological_tests_of...

    [2] in other words, when some factor is sufficient to cause an effect, the presence of the cause guarantees the occurrence of the effect. [3] However, a different cause z may also cause y, meaning that y may occur without x occurring. [2] [3] For a concrete example, consider the conditional statement "if an object is a square, then it has four ...

  3. Developmental systems theory - Wikipedia

    en.wikipedia.org/wiki/Developmental_systems_theory

    For example, there is vigorous resistance to the widespread assumptions that one can legitimately speak of genes ‘for’ specific phenotypic characters or that adaptation consists of evolution ‘shaping’ the more or less passive species, as opposed to adaptation consisting of organisms actively selecting, defining, shaping and often ...

  4. Biopsychosocial model - Wikipedia

    en.wikipedia.org/wiki/Biopsychosocial_model

    Biopsychosocial models are a class of trans-disciplinary models which look at the interconnection between biology, psychology, and socio-environmental factors. These models specifically examine how these aspects play a role in a range of topics but mainly psychiatry , health and human development.

  5. Biological basis of personality - Wikipedia

    en.wikipedia.org/wiki/Biological_basis_of...

    Brain imaging has catalyzed research of the neurobiological correlates of personality. [3] Molecular genetics: This method is used to analyze a gene-trait link, by measuring the structure and function of genes in the brain. [15] The use of molecular genetics in biology-based personality research is expected to grow. [7] Molecular assays

  6. Population ecology - Wikipedia

    en.wikipedia.org/wiki/Population_ecology

    Carrying capacity is only found during a density-dependent population. Density-dependent factors influence the carrying capacity are predation, harvest, and genetics, so when selecting the carrying capacity it is important to understand to look at the predation or harvest rates that influence the population (Stewart 2004).

  7. Design of experiments - Wikipedia

    en.wikipedia.org/wiki/Design_of_experiments

    The use of a sequence of experiments, where the design of each may depend on the results of previous experiments, including the possible decision to stop experimenting, is within the scope of sequential analysis, a field that was pioneered [12] by Abraham Wald in the context of sequential tests of statistical hypotheses. [13]

  8. List of research methods in biology - Wikipedia

    en.wikipedia.org/wiki/List_of_research_methods...

    A research design that involves multiple measures of the same variable taken on the same or matched subjects either under different conditions or over two or more time periods. [ 1 ] Paired t-test , Wilcoxon signed-rank test

  9. Competition (biology) - Wikipedia

    en.wikipedia.org/wiki/Competition_(biology)

    An example among animals could be the case of cheetahs and lions; since both species feed on similar prey, they are negatively impacted by the presence of the other because they will have less food, however, they still persist together, despite the prediction that under competition one will displace the other. In fact, lions sometimes steal ...
