Mentha, also known as mint (from Greek μίνθα míntha, [2] Linear B mi-ta [3]), is a genus of flowering plants in the mint family, Lamiaceae. [4] It is estimated that 13 to 24 species exist, but the exact distinction between species is unclear. [5] [1] Hybridization occurs naturally where some species' ranges overlap. Many hybrids and ...
Steller's jay shows a great deal of regional variation throughout its range. Blackish-brown-headed birds from the north gradually become bluer-headed farther south. [8] Steller's jay has a more slender bill and longer legs than the blue jay and, in northern populations, has a much more pronounced crest. [9]: 69 [10] It is also somewhat larger.
Now, for each node in the tree, add another interval tree on the x-ranges, for all elements whose y-range is the same as that node's y-range. The advantage of this solution is that it can be extended to an arbitrary number of dimensions using the same code base.
Having geographically separate, non-overlapping ranges of distribution. [17] Contrast sympatric. alternate 1. (adj.) (of leaves or flower s) Borne singly at different levels along a stem, including spiralled parts. Contrast opposite. 2. (prep.) Occurring between something else, e.g. stamen s alternating with petal s. alternipetalous
TypeScript supports intersection types, [5] improving expressiveness of the type system and reducing potential class hierarchy size, demonstrated as follows.. The following program code defines the classes Chicken, Cow, and RandomNumberGenerator that each have a method produce returning an object of either type Egg, Milk, or number.
Orthosiphon aristatus, commonly known as cat's whiskers or Java tea, is a plant species in the family Lamiaceae (also known Labiatae). The plant is a medicinal herb found mainly throughout southern China , the Indian Subcontinent , South East Asia , and tropical Queensland , Australia.
Character displacement was first explicitly explained by William L. Brown Jr. and E. O. Wilson in 1956: "Two closely related species have overlapping ranges. [1] In the parts of the ranges where one species occurs alone, the populations of that species are similar to the other species and may even be very difficult to distinguish from it.
Mountain ranges often create such ecotones, due to the wide variety of climatic conditions experienced on their slopes. They may also provide a boundary between species due to the obstructive nature of their terrain. Mont Ventoux in France is a good example, marking the boundary between the flora and fauna of northern and southern France. [7]
