(Entry 1 of 2) : a gradient of morphological or physiological change in a group of related organisms usually along a line of environmental or geographic transition.

1 : a feeling of liking and caring for someone or something : tender attachment : fondness She had a deep affection for her parents. 2 : a moderate feeling or emotion.

A cline is the specific set of traits in a population of a given species that have been influenced by the local environment. For example, a population of warm-blooded animals that lived in a cooler climate closer to the North Pole would have larger bodies, allowing them to better conserve heat.

The existence of a cline suggests natural selection because of the close association between the environmental variable and the frequency of the allele. 7. These mutations provide the raw material from which new traits may arise and be selected.

Microevolution happens on a small scale (within a single population), while macroevolution happens on a scale that transcends the boundaries of a single species. Despite their differences, evolution at both of these levels relies on the same, established mechanisms of evolutionary change: mutation.

An ecotype is a population (or subspecies or race) that is adapted to local environmental conditions. The implication is that those individuals which were best adapted to the prevailing conditions left the most offspring.

The notions “form” and “ecotype” may appear to correspond to a static phenomenon, however; this is not always the case. Evolution occurs continuously both in time and space, so that two ecotypes or forms may qualify as distinct species in only a few generations.

An ecad is a type of plant that has evolved to live in a very distinct area. When the seeds of a plant that has only ever grown in the open expanse and sunshine-laden fields are transplanted to the shade of a forest and they produce plants then the plants are called ecads. Such a plant becomes known as an ecad.

Ecotype is a race of a plant and animal species to acquire a particular habitat. Ecoline describes the ecotone. Ecophene is a variety of a phenotype. Ecotone is a region of transmission between biological communities.

An estuary is a place where a river or a stream opens into the sea (mouth of the river). Estuaries form a transition zone (ecotone) between river environments and maritime environments. Examples of estuaries are river mouths, coastal bays, tidal marshes, lagoons and deltas.

An Ecotone describes an area that acts as a transition or boundary between two ecosystems. Ecotones are considered areas of great environmental importance. As well as providing an area for a large number of species, they often experience influx from animals looking to nest or searching for food.

Basically, fragility and stability of an ecosystem relate to degree of change in species abundance and composition, following disturbance. High rates of species turnover or population fluctuations characterize fragile ecosystems, and vice versa.

The Tundra-Taiga Ecotone (TTE) is the earth’s longest vegetation transition zone and stretches for more than 13,400 km around Arctic North America, Scandinavia, and Eurasia.

Ecotone, a transitional area of vegetation between two different plant communities, such as forest and grassland. It has some of the characteristics of each bordering biological community and often contains species not found in the overlapping communities.
