Population dynamics within a patch were simplified to the point where ...

Population dynamics

... Population dynamics is the study of marginal and long-term changes ... processes influencing those changes. Population dynamics is the dominant branch of mathematical biology , ... some of these population dynamics. Population dynamics also attempts to study topics such as aging ...

Adaptive radiation

... able to expand their territory into the air, or the development of lung fish during the Devonian period , about 300 million years ago. The dynamics of adaptive radiation is such that, within a relatively short time, many species derive from a single or a few ancestor species. From this large ...

Biodiversity

... For geneticists , biodiversity is the diversity of genes and organisms . They study processes such as mutations, gene exchanges, and genome dynamics that occur at the DNA level and generate evolution. For biologists , biodiversity is the diversity of populations of organisms and species, but ...

Biochemistry

... development of new techniques such as chromatography , X-ray diffraction , NMR , radioisotopic labelling , electron microscopy and molecular dynamics simulations. These techniques allowed for the discovery and detailed analysis of many molecules and metabolic pathways of the cell , such as ...

Digital organism

... A digital organism is a self-replicating computer program that mutates and evolves . Digital organisms are used as a tool to study the dynamics of Darwinian evolution , and to test or verify specific hypotheses or mathematical models of evolution. Contents ...

Fitness landscape

... strategies. In evolutionary optimization, one tries to solve real-world problems (e.g., engineering or logistics problems) by imitating the dynamics of biological evolution. For example, a delivery truck with a number of destination addresses can take a large variety of different routes, but only ...

Human

... of individuals of similar age, typically of the size of ten to twenty individuals, possibly related to the optimal size of a hunting party. Group dynamics and peer pressure may substantially influence the behaviour of group members. (See also Asch conformity experiments .) Larger groups of humans ...

Population

... a particular species —living in a given geographic area . Population is studied in a wide variety of ways and disciplines. In population dynamics , size, age and sex structure, mortality, reproductive behaviour, and growth of a population are studied. Demography is the study of human ...

Sociobiology

... processes they are dealing with which can best be used to come to "politically preferred" conclusions. For example, including the complete genetic dynamics of in- and outbreeding might lead to completely different conclusions in the above-mentioned theories of the adaptive nature of racism. Also, it is ...

Stem cell

... in 2003 for his work. His team successfully grew adult stem cells harvested from the human nose, and was published in the journal Developmental dynamics . The Courier-Mail cited him as follows (22 March 2005, p. 4): Adult stem cells isolated from the olfactory mucosa (cells linking the inside ...
