An ecotype refers to organisms which belong to the same species but have different phenotypical characteristics as a result of their adaptations to different habitats. [6] Differences between these two groups is attributed to phenotypic plasticity and are too few for them to be termed as wholly different species. [ 7 ]
Animals categorized by adaptation or ecological niche; Subcategories. This category has the following 29 subcategories, out of 29 total. ...
Adaptation affects all aspects of the life of an organism. [24] The following definitions are given by the evolutionary biologist Theodosius Dobzhansky: 1. Adaptation is the evolutionary process whereby an organism becomes better able to live in its habitat or habitats. [25] [26] [27] 2.
A well-known example of a specialist animal is the monophagous koala, which subsists almost entirely on eucalyptus leaves. The raccoon is a generalist, because it has a natural range that includes most of North and Central America, and it is omnivorous, eating berries, insects such as butterflies, eggs, and various small animals.
Phenotypic plasticity refers to some of the changes in an organism's behavior, morphology and physiology in response to a unique environment. [1] [2] Fundamental to the way in which organisms cope with environmental variation, phenotypic plasticity encompasses all types of environmentally induced changes (e.g. morphological, physiological, behavioural, phenological) that may or may not be ...
[53] [55] This is to compensate for the low oxygen environment. This adaptation is associated with developmental patterns such as high birth weight, increased lung volumes, increased breathing, and higher resting metabolism. [56] [57] The genome of Tibetans provided the first clue to the molecular evolution of high-altitude adaptation in 2010. [58]
Several groups of tetrapods have undergone secondary aquatic adaptation, an evolutionary transition from being purely terrestrial to living at least part of the time in water. These animals are called "secondarily aquatic" because although their ancestors lived on land for hundreds of millions of years, they all originally descended from ...
A very sophisticated adaptation utilized by a small number of species is a tail-like flagellum that can adjust vertical position, and allow movement in any direction. [2] Phytoplankton can also maintain their presence in the water column by being circulated in Langmuir rotations. [3] Periphytic algae, on the other hand, are attached to a substrate.
