n.
A genetically distinct population of plants, animals, or other organisms that is found in a particular habitat.

e′co·typ′ic (-tĭp′ĭk) adj.

ecotype

the product arising as a result of the response of the GENOTYPE of an organism to the particular habitat in which it lives, for example, Plantago maritima has a height of about 17.5 cm in waterlogged mud and 56 cm in fertile meadow. See also PHENOTYPIC PLASTICITY.

Lowland ecotypes are found in floodplains and are taller (around 6 feet), coarser with a more bunch-type growth habit and may be more rapid growing than upland ecotypes.
2]) and % total area covered by each of 6 terrestrial vegetation ecotypes sampled on the Kabetogama Peninsula, Voyageurs National Park (VNP), Minnesota, USA, June- September 2011.
The interaction of ecotype x fertilizer indicated that the maximum weed dry weight was recorded for Ghreghozlo and Malekkandi ecotypes (43.
This collection of articles and photographs gives managers a good idea of recent research into what the sockeye salmon is and does, covering such topics as the vulnerability and value of sockeye salmon ecotypes, their homing ability, using new technologies to monitor reproduction, DNA and a founder event in the Lake Clark sockeye salmon, marine-derived nutrients, the exploitation of large prey, dynamic lake spawning migrations by females, variability of sockeye salmon residence, expression profiling using cDNA microarray technology, learning from stable isotropic records of native otolith hatcheries, the amount of data needed to manage sockeye salmon and estimating salmon "escapement.
McFarland & Hoy (2001) suggested that populations from Vietnam and Taiwan were different ecotypes based on their different responses to relative humidity.
Khan said that at present domesticated quinoa ecotypes have diverse characters which makes it a peculiar crop to be used for different purposes including making soaps, toasting, grains, flour and high nutritional enhancement.
The goals of this project are: 1) to estimate the evolutionary relationships among Floridian Geolycosa populations and species and between Floridian Geolycosa and Geolycosa from the rest of the USA and, 2) to examine patterns in the evolution of the two ecotypes of Geolycosa: those that build turrets at the entrance of their burrow and those that don't.
The reasons are many, but, stated as briefly as possible, one can say the following: the mountains--a massif and associated plateau whose high point is 8,646 feet above sea level--are (or were, for things are changing very fast) a true paradise for ethnographers, anthropologists, linguists, botanists, and zoologists on account of the fact that they can be stratified, vertically, into about ten ecotypes (moist deciduous forests, moist evergreen tropical and subtropical forests, dry deciduous forests, savanna woodlands, savanna grasslands, shrub savannas, temperate forests, so-called "sholas' temperate grasslands, close thorny thickets, and discontinuous thorny thickets).
This variation in results has been attributed to species physiological responses, varying species competitive abilities, and the possibility that some taxa have one or more ecotypes that are identical or vary similar morphologically but differ in their physiological requirements (6).
To test this, we conducted a greenhouse study to evaluate switchgrass's tolerance of soil moisture stress at various levels of water availability, ranging from moisture deficit to flooded, and we also assessed the germination, establishment, performance and reproductive potential of four common ecotypes, both upland and lowland (Barney et al.
