Climax community - Biocrawler The term climax community is an outdated ecological term for a community of plants and animals which is the result of succession, where a biological system, a community, or a soil has reached a steady state. The idea of a single climatic climax originates with Frederic Clements' idea of the ecological community as an organic superorganism in which the various stages of successional development could be seen as analogous with the ontological development of an organism. Later developments in the field of ecology saw the decline of climax theory; theories which took into account the fact that the timelines required for the development of climax vegetation were unrealistically long, and most vegetation could better be explained by more stochastic factors. www.biocrawler.com /encyclopedia/Climax_%28biology%29   (334 words)

SparkNotes: SAT Subject Test: Biology: Ecological Succession While individuals within a climax community will come and go, the essential makeup of the populations within the climax community will stay constant. The community has reached its climax community, with maple as the dominant species. And as trees come to dominate, the climax community will arise from a species that can grow in the shade of its neighbors. www.sparknotes.com /testprep/books/sat2/biology/chapter10section4.rhtml   (889 words)

NONDUAL ECOLOGY Biology is a series of provisional sketches for negentropic systems. This marriage of biology and technology may have to arise again and again, and again, until some incredibly lucky combination of biological traits falls in symbiosis with a perfect, sweet and sensitive technology. This rush to apocalypse may function as a form of population control of civilizations, and is governed by biological/cultural laws as implacable as those which mandate the death of individuals and the inevitable extinction of all species. spot.colorado.edu /~mcclelr/NondualEcology.htm   (7189 words)

Climax community - Wikipedia, the free encyclopedia The term climax community, also described as a climatic climax community is a largely obsolete ecological term for a biological community of plants and animals which, through the process of succession - the development of vegetation in an area over time - has reached an equilibrium or steady state. Though the views are sometimes attributed to him, Clements never argued that climax communities must always occur, or that the dominant cause of vegetation is climate, or that the different species in an ecological community are tightly integrated physiologically, or that plant communities have sharp boundaries in time or space. Though climax theory is no longer itself popular in ecology, many authors and nature-enthusiasts continue to use the term "climax" in a diluted form to refer to what might otherwise be called mature or old-growth communities. en.wikipedia.org /wiki/Climax_(biology)   (939 words)

Soils retrogression and degradation - Wikipedia, the free encyclopedia It is due to the replacement of the primitive vegetation (known as climax) by a secondary vegetation. The climax vegetation is gradually replaced and the soil modified (example: replacement of leafy tree forests by moors or pines plantations). biological diversity: soil degradation may involve the disappearance of the climax vegetation, the decrease in animal habitat, thus leading to a biodiversity loss and animal extinction... en.wikipedia.org /wiki/Soils_retrogression_and_degradation   (1331 words)

Succession A climax community is in equilibrium with its habitat--it has reached a steady state. Theoretically, the climax (in eastern North American deciduous forest) is beech-maple, but if, for example, the forest is growing on an upland, well-drained slope where there is drier soil, the community may only go to oak-hickory.

Environmental Biology Sequence - Grasslands The characteristic plants which define each of the biomes constitute part of what is known as the climax community.

Succession When the changes in the composition of plants stop and the plant community remains generally the same for many years, the community is mature or at climax. A climax community is the relatively stable community at the end of succession. The plants and animals that are able to live in a certain area are determined by abiotic conditions such as climate, amount of water, and soil type. www.iadeaf.k12.ia.us /Succession.htm   (514 words)

Kansas School Naturalist: The Role of Animals in Succession A climax community perpetuates itself and is not followed by a different subsequent community. Climax communities were once considered "stable" or unchanging in their composition, but more recent research shows the climax plant and animal community is in a constant state of flux. If this was a climax community, the distribution of young and old plant and animal species would not show a directional change. www.emporia.edu /ksn/v43n1-december1996/KSNVOL42-1.htm   (3636 words)

Ecology Part 2 Notes The Climax Community represents an assemblage of organisms which are self-perpetuating, that is to say when a tree, for example, dies due to wind, fire, or other damage, it is generally replaced with one of its own kind (i.e., the same species). In contrast, Equalibrium Species are those associated with later stages of succession, even the climax stage, and are k-selective in reproductive strategy, large in body size, and reproduce in small numbers. Species diversity is very high in climax community, in contrast to low species diversity in early stages of succession. www.cst.cmich.edu /users/baile1re/bio101fall/ecol-2/eco2note.htm   (2173 words)

Last check: ) By contrast, whole-body corticosterone content of X. laevis was highest during premetamorphosis, declined at the onset of prometamorphosis, increased at metamorphic climax and remained at climax levels in juvenile frogs. Based on plasma- or whole-body corticoid content, interrenal enzyme activity, and histology, the interrenal glands are considered generally to be less active in early, premetamorphic developmental stages and more active during prometamorphosis and metamorphic climax. HSD activity increases at metamorphic climax in R. catesbeiana (Hsu et al., 1980), and Carr and Norris (1988) found a similar pattern for plasma corticosterone and interrenal HSD activity in the tiger salamander, Ambystoma tigrinum. www.findarticles.com /p/articles/mi_qa4054/is_200206/ai_n9119418   (815 words)

The Material Nature of Spirituality Their extensive observations of praying Franciscan nuns and meditating Buddhist monks reveal that certain religious experiences like meditation and prayer are linked to heightened activity and changes in the material structure of the brain and nervous system. This was compared with the brain scan taken when the subject indicated he/she was at the 'climax' of her spiritual experience (3). The frontal lobes of the brain, which are associated with attention, showed increased activity (1).This was expected since greater concentration and focus was essential to meditation and prayer. serendip.brynmawr.edu /biology/b103/f01/web3/ekanayake.html   (1517 words)

Lecture Outline A climax community is the most persistent array of species that results after some lapse of time. In secondary succession, a community reestablishes itself to a climax state after a disturbance that allows sunlight to penetrate. According to the climax-pattern model, a community is adapted to a total pattern of environmental factors--climate, soil, topography, wind, fires, etc.--to create a continuum of climax stages of succession. www.brookscole.com /biology_d/templates/student_resources/0534388000_starr/lecture_outlines/ch47.html   (1437 words)
