Citations needed date November 2007 Mergefrom bio based material date July 2008 Biotic material or biological derived material is any natural material that is originated from living organisms. Most such materials contain carbon and are capable of decay. Examples of biotic materials are wood , linoleum , straw , humus , manure , bark , crude oil , cotton , spider silk , chitin , fibrin , and bone . The use of biotic materials, and processed biotic materials bio based material as alternative natural materials , over synthetics is popular with those who are environmentally conscious because such materials are usually biodegradable, renewable, and the processing is commonly understood and has minimal environmental impact. However, not all biotic materials are environmentally friendly, such as those that require high levels of processing, are harvested unsustainably, or are used to produce greenhouse gasses carbon emission s. When the source of the recently living material has little importance to the product produced, such as in the production of biofuel s, biotic material is simply called biomass . Many fuel sources may have biological sources, and may be divided roughly into fossil fuels , and biofuel . In soil science , biotic material is often referred to as organic matter . Biotic materials in soil include glomalin , Dopplerite and humic acid . Some biotic material may not be considered to be organic matter if it is low in organic compounds , such as a clam s shell, which is an essential component of the living organism, but contains little organic carbon. Examples of the use of biotic materials include Alternative natural materials building material , for a stylistic reasons, or to reduce allergic reactions. clothing energy industry energy production food drugs medicine ink composting and mulch DEFAULTSORT Biotic Material Category Natural materials Category Composting Category Sustainable technologies ... more details
Unreferenced date December 2010 Biotic components are the living things that shape an ecosystem . A biotic factor is any living component that affects another organism , including animal s that consume the organism in question, and the living food that the organism consumes. Biotic factors include human influence. Biotic components are contrasted to abiotic component s, which are non living components of an organism s environment, such as temperature, light, moisture, air currents, etc. Biotic components usually include Producers, i.e. autotroph s e.g. plants they convert the energy from the sun, or other sources such as hydrothermal vent s into food. Consumers, i.e. heterotroph s e.g. animals they depend upon producers for food. Decomposers, i.e. detritivore s e.g. fungi and bacteria they break down chemicals from producers and consumers into simpler form which can be reused.

Cleanup date February 2008 Unreferenced date February 2008 Biotic potential is the maximum reproductive capacity of a population if resources are unlimited. Full expression of the biotic potential of an organism is restricted by environmental resistance , any condition that inhibits the increase in number of the population. It is generally only reached when environmental conditions are very favorable. A species reaching its biotic potential would exhibit exponential population growth and be said to have a high fertility , that is, how many offspring are produced per mother. Biotic Potential is a fundamental species characteristic, defined by Chapman 1925 as the inherent power of organisms to reproduce and survive ref Chapman, R. N., 1925. Animal Ecology with Special Reference to Insects. Burgess Brook Inc.,Minneapolis. 370 pp. See pp.158 161. ref . In 1931, Chapman redescribed it as It is a sort of algebraic sum of the number of young produced at each reproduction, number of reproductions over a period of time, sex ratio of the species, and their general ability to survive under given physical conditions. ref Chapman, R. N. 1931 Animal Ecology. McGraw Hill, New York ref Chapman relates to a vital index Vital Index number of births number of deaths 100 Biotic potential is the highest possible vital index of a species therefore, when the species has its highest birthrate and lowest mortality rate.

Biotic stress is stress biological stress that occurs as a result of damage done to plants by other living organisms, such as bacteria, viruses, fungi, parasites, beneficial and harmful insects, weeds, and cultivated or native plant s. Agriculture It is a major focus of agricultural research, due to the vast economic losses caused by biotic stress to cash crops. The relationship between biotic stress and plant yield affects economic decisions as well as practical development. The impact of biotic injury on crop yield impacts population dynamics , plant stressor coevolution , and ecosystem nutrient cycling. ref Robert K.D. Peterson, Leon G. Higley. Biotic Stress and Yield Loss. 2001. ref Biotic stress also impacts horticultural plant health and natural habitat s ecology.

Biotic Index is a scale for showing the quality of an natural environment environment by indicating the types of organism s present in it. It is often used to assess the water quality quality of water in river s. It is measured from 1 to 10 and corresponds to the four basic water quality Excellent, Good, Fair or Poor . The concept of the Biotic Index was developed by William M. Beck in an effort to provide a simple measurement of stream water pollution pollution and its effects on the biology of the stream To assign a biotic index value to a specific water site, the tester first collects macroinvertebrates from portions of the sample area of the stream, river or lake and separate them into groups of similar looking organisms. More extensive testing can be done by looking for certain microscopic organisms. Then an identification key is used to help determine which category or group the organism belongs in and allows a numerical value be assigned to that organism. A worksheet is then used to calculate the final value or score of all the organisms found. Depending upon the worksheet s equations, the score determines the condition of the water quality. Why Macroinvertebrates Aquatic macroinvertebrates have some general characteristics that make them very useful to assess stream health. 1. They are abundant and found in water bodies throughout the world. 2. They are not extremely mobile. 3. They carry out part or all of their life cycle within the stream or river. Macroinvertebrates limited mobility and extended presence in the water means that they are exposed on a continuous basis to water quality in that stream or river. In particular, many of these organisms breath dissolved ... found in samples are listed on the biotic index scoring sheets.

Orphan date February 2009 Semi biotic systems are systems that incorporate biologically derived components modules which could range from multi protein complexes through DNA constructs to multi cellular assemblies and integrate them with synthetic components e.g. microfabricated systems to produce hybrid devices. One of the potential attractions of these hybrid devices is the possibility that they can be designed to exhibit higher degrees of adaptability and autonomy than is possible with solid state devices. Examples include artificial organelle like systems that could accomplish the synthesis of complex biomacromolecules, or synthetic multi cellular structures that incorporate specific sensing and reporting functionalities, such that they could be used in hybrid devices for chemical or biological agent sensing. Semi biotic systems is an emerging area of research within the broader area of Synthetic Biology .

Unreferenced stub auto yes date December 2009 An environmental gradient is a gradual change in abiotic factors through space or time . Environmental gradients can be related to factors such as altitude, temperature, depth, ocean proximity and soil humidity. Species Abundance ecology abundance s usually change along environmental gradients in a more or less predictive way. However, the species abundance along an envronmental gradient is not only determined by the abiotic factor but, also by the change in the biotic interaction s along the environmental gradient. At an ecotone , species Abundance ecology abundance s change relatively quick compared to the environmental gradient.

Summary Information Description Typical regrowth of eucalypt trees Eucalyptus cypellocarpa , 15 months after a bushfire has gone through the Grampians National Park in Southeast Australia. The smaller trees thinner stem and twigs have not survived the bushfire, while the larger trees thicker stem and twigs have survived. Because the small twigs in the crown of the tree have also been burned, the trees had to sprout at a different spot, this has resulted in massive resprouting along the base of the tree, instead of in the crown. The inset clearly shows this resprouting of the tree over the whole length of the stem. Source self made Date April 2007 Location Fire Ecology Biotic adaptations and responses A.
