Citations needed date November 2007 Biotic material or biological derived material is any material that originates 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
Cleanup date February 2008 Refimprove 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. 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 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. Each biotic factor neto 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.

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.

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 .

Orphan date November 2006 Realized nich width is a phrase relating to ecology defining the actual space that an organism inhabits and the resources it can access as a result of limiting pressures from other species e.g. superior competitors . Niche width v. realized niche width The niche width of an organism refers to a theoretical range of conditions that a species could inhabit and successfully survive and reproduce with no competition. The niche width is defined as the parameters of this range which are determined by biotic and abiotic factors such as suitable climate and appropriate food sources. The niche width often differs from the area that a species actually inhabits, which is called its realized niche width . This is due to interspecific competition with other species within their ecosystem and other biotic and abiotic limiting factors. A species realized niche is usually much narrower than its theoretical niche width as it is forced to adapt its niche around superior competing species. The physical area where a species lives, is its habitat. The abstract hypercube that defines the limits of environmental features essential to that species survival, is its niche.

Unreferenced date May 2009 A pollenizer or polleniser , sometimes pollinizer or polliniser see ise vs ize spelling differences is a plant that provides pollen . In American English, the words pollenizer and pollination pollinator are often confused A pollinator is the Biotic component biotic agent that moves the pollen, such as bee s, moth s, bat s, and bird s. In UK English it is quite correct to refer to different varieties as pollinators . Bees are normally referred to as pollinating insects . The verb form to pollenize , is to be the Pollen source source of pollen , or to be the sire of the next plant generation. While some plants are capable of self pollenization, the term is more often used in pollination management as a plant that provides abundant, compatible, and viable pollen at the same flower ing time as the pollenized plant. For example most crabapple varieties are good pollenizers for any apple fruit apple variety that blooms at the same time, and are often used in apple orchards for the purpose. Some apple cultivar s produce very little pollen some produce pollen that is sterile, or incompatible with other apple varieties. These are poor pollenizers. A pollenizer can also be the male plant in Plant sexuality dioecious species where entire plants are of a single sex , such as with kiwifruit or holly . Plants are sometimes mistakenly called pollinators. For example, some Nursery horticulture nursery catalogs may say variety X should be planted as a pollinator for variety Y, when they actually should be referring to it as a pollenizer. Strictly, a plant can only be a pollinator when it is self fertile and it physically pollinates itself without the aid of an external pollinator, as in the case of apomictic species like some rowan s and Crataegus hawthorn s.

This term is used mainly in the Czech Republic , where it was introduced by several studies in 1960s. Distinctiveness of deep river valleys is based on their sharp contrast to softly undulating landscape, prevailing in middle elevations of Czech. Steep slopes, exposed rocks pronouncing the effect of geological substrate on vegetation, contrast between the sunny and warm southerly oriented slopes and shaded cold northerly oriented slopes, high diversity of various extreme habitats situated next to each other, specific Microclimate microclimatic conditions causing frequent temperature inversion s, the main feature for existence of river phenomenon. The main biotic consequences are 1 high biodiversity located in deep river valleys, 2 concentration of relict species, resulting from the fact, that deep river valleys served as a Refugium population biology refugia for plant and animal species during the era of ice age , 3 function of river valley as a corridor for migration of plants and animals, connecting mountain areas with lowlands, and 4 preservation of the vegetation relatively unaffected by human activities for its inaccessibility. Although river phenomenon has been applied mainly to Central Europe, it could be related to riverine landscapes, with the view focused specifically on rivers with deep, narrow valleys.
