Source–sink dynamics is a theoretical model used by ecologists to describe how variation in habitat quality may affect the population growth or decline of organisms.. Since quality is likely to vary among patches of habitat, it is important to consider how a low quality patch might affect a population.
From left to right: a field with a source, a field with a sink, a field without either. In the physical sciences, engineering and mathematics, sources and sinks is an analogy used to describe properties of vector fields. It generalizes the idea of fluid sources and sinks (like the faucet and drain of a bathtub) across different scientific ...
The source Q is the flux of material into the reservoir, and the sink S is the flux of material out of the reservoir. The budget is the check and balance of the sources and sinks affecting material turnover in a reservoir. The reservoir is in a steady state if Q = S, that is, if the sources balance the sinks and there is no change over time. [25]
The relationship between the sum of the current sources and sinks and the voltage measured by the microelectrode probe may be calculated analytically if it is assumed that the quasi-static assumption holds, that the medium is spherically symmetric, homogeneous, isotropic, and infinite, and if the current source or sink is modeled as a point ...
Minimum viable population (MVP) is a lower bound on the population of a species, such that it can survive in the wild. This term is commonly used in the fields of biology, ecology, and conservation biology.
All women have evolved to be beautiful, in an illustration by Paul Merwart for a 1911 edition of Camille Flammarion's 1894 novel La Fin du Monde.. Evolution has been an important theme in fiction, including speculative evolution in science fiction, since the late 19th century, though it began before Charles Darwin's time, and reflects progressionist and Lamarckist views as well as Darwin's.

The Tales of Known Space were first published primarily as short stories or serials in science fiction magazines. Generally the short fiction was subsequently released in one or more collections and the serial novels as books. Some of the shorter novels (novellas) published in magazines were expanded as, or incorporated in, book-length novels.
Darko Ronald Suvin (born Darko Šlesinger) is a Canadian academic, writer and critic who became a professor (now emeritus [1]) at McGill University in Montreal. He was born in Zagreb, which at the time was in Kingdom of Yugoslavia, now the capital of Croatia.
