BulNet offers linguistic solutions at the semantic level such as options for synonym selection, queries for semantic relations of a word in the language's lexical system (antonymy, holonymy, etc.), explanatory definition queries and translation equivalents for a lexical item.
Species from the collections have geographically diverse origins, are generally well-described and fixed for traits of agronomic or scientific interest, and have available passport data. [30] Meise Botanical Garden houses a seed bank in Belgium. Among other things, it aims to preserve endangered and rare wild species of Belgian flora.It also ...
Adaptation to diverse positions and climatic conditions could be a significant source of genetic differences and population isolation. Pleiotropic-induced sexual selection between individuals of these genetically diverse populations can be caused by biological features selected for in each habitat.
Varieties of maize in the office of the Russian plant geneticist Nikolai Vavilov. A study conducted by the National Science Foundation in 2007 found that genetic diversity (within-species diversity) and biodiversity are dependent upon each other — i.e. that diversity within a species is necessary to maintain diversity among species, and vice versa.
In evolutionary biology, adaptive radiation is a process in which organisms diversify rapidly from an ancestral species into a multitude of new forms, particularly when a change in the environment makes new resources available, alters biotic interactions or opens new environmental niches.
The word neurodiversity first appeared in publication in 1998, in an article by American journalist Harvey Blume, [24] as a portmanteau of the words neurological diversity, which had been used as early as 1996 in online spaces such as InLv to describe the growing concept of a natural diversity in humanity's neurological expression.

Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, ...
Selection bias amongst researchers may contribute to biased empirical research for modern estimates of biodiversity. In 1768, Rev. Gilbert White succinctly observed of his Selborne, Hampshire "all nature is so full, that that district produces the most variety which is the most examined."
