As the traits that improve wheat as a food source also involve the loss of the plant's natural seed dispersal mechanisms, highly domesticated strains of wheat cannot survive in the wild.

Population dispersal is used to describe migratory events, either in the form of range expansion ( natural movement away from parents ) or jump dispersal ( crossing of barriers ), which may lead to genetic isolation.

Flock sizes are affected by the small numbers remaining in the species and, given their largely carnivorous diet, some feeding dispersal is needed in natural conditions.

Ferrets are typically released in the fall during their natural dispersal and kits ( young of the year ) are the primary candidates.

Plant propagation can also refer to the artificial or natural dispersal of plants.

Baboons are important in their natural environment not only serving as food for larger predators, but also aiding in seed dispersal due to their messy foraging habits.

Every aspect of the ecosystem from the different species of plants to the diversity of animal species contributes to natural services like water purification, provision of food, fuel, fiber, and biochemicals, nutrient cycling, pollination and seed dispersal, and climate regulation, just to name a few.

Lastly, the presence of seed dispersers and animal dispersed species of trees in some grassland plots suggest that suppressing fire and allowing natural seed dispersal to occur can encourage forest regeneration.

The natural inorganics include various types of stones ( from gemstones to common minerals ) and metals.

In that early form of chemical science, it was believed by many that the best way to heat certain materials was to mimic the supposed natural processes, occurring in the Earth's core, by which precious metals were believed to be germinated.

The presence of heavy metals in the clinker arises both from the natural raw materials and from the use of recycled by-products or alternative fuels.

Alternatively, domino sets have been made from many different natural materials: stone ( e. g., marble, granite or soapstone ); other hardwoods ( e. g., ash, oak, redwood and cedar ); metals ( e. g., brass or pewter ); ceramic clay, or even frosted glass or crystal.

Economic geologists help locate and manage the Earth's natural resources, such as petroleum and coal, as well as mineral resources, which include metals such as iron, copper, and uranium.

Natural resources: abundant hydropower ; significant deposits of gold and rare earth metals ; locally exploitable coal, petroleum, and natural gas ; other deposits of nepheline, mercury, bismuth, lead, and zinc.

Other industries include agricultural goods, textiles, wood products, construction materials, gems, metals, oil and natural gas.

Oil, natural gas, metals, and timber account for more than 80 % of Russian exports abroad.

Of the seven metals known in antiquity only gold occurred regularly in native form in the natural environment.

Pure, regular crystals can sometimes be obtained from natural or synthetic materials, such as samples of metals, minerals or other macroscopic materials.

Although the country is rich in natural resources, the economy is mainly bolstered by agriculture, food processing, lumber, oil, cement, chemicals, mining, basic metals, hydropower, tourism, textile industry, migrant remittances, and the informal economy.

Hittite prosperity largely depended on Hittite control of trade routes and natural resources, specifically metals.

Because of the way their regular crystalline atomic structure causes their spins to interact, some metals are ferromagnetic when found in their natural states, as ores.

Oil, natural gas, metals, and timber account for more than 80 % of Russian exports, leaving the country vulnerable to swings in world prices.

Central to the modern world economy, it converts raw materials ( oil, natural gas, air, water, metals, and minerals ) into more than 70, 000 different products.

Hubbert models have been used to predict the production trends of various resources, such as natural gas ( Hubbert's attempt in the late 1970's resulted in an inaccurate prediction that natural gas production would fall dramatically in the 1980's ), Coal, fissionable materials, Helium, transition metals ( such as copper ), and water.

Tomsk Oblast is rich in natural resources, particularly oil, natural gas, ferrous and non-ferrous metals, peat, and underground waters.

Through a series of natural treatment processes – including the use of Eichhornia crassipes and other plants for absorbing oil, grease and heavy metals – the Cooperative has turned the area into a thriving fish farm and nature park.

Together with osmium ( bluish ), and gold ( yellow ), copper is one of only three elemental metals with a natural color other than gray or silver.

Heavy metals enter the environment through oil spills – such as the Prestige oil spill on the Galician coast – or from other natural or anthropogenic sources.

These acids damage the red spruce trees in part by releasing natural metals from the soil like aluminum, and by leaching important minerals.

The phrase " sin indios no hay Indias " ( without Indians, there are no Indies – i. e. America ), popular in America especially in the 16th century, emphasizes the economic importance and appeal of this indentured labor, even above that of precious metals or other natural resources.

Animism encompasses the beliefs that there is no separation between the spiritual and physical ( or material ) world, and souls or spirits exist, not only in humans, but also in all other animals, plants, rocks, geographic features such as mountains or rivers, or other entities of the natural environment.

Facilitation, or the positive interactions between different species of plants, is an intricate web of association in a natural environment.

Anti-globalization advocates urge that preservation of the natural environment, human rights ( especially workplace rights and conditions ) and democratic institutions are likely to be placed at undue risk by globalization unless mandatory standards are attached to liberalisation.

It is recommended that the tank mimic their natural environment, so artificial or natural rock is highly appreciated.

In addition to pollution through human activities, millions of tons of petroleum enter the marine environment every year from natural seepages.

Background radiation is the ionizing radiation constantly present in the natural environment of the Earth, which is emitted by natural and artificial sources.

The beak of each species is suited to the food available in its particular environment, suggesting that beak shapes evolved by natural selection.

The finch is also found on the main land and it is thought that they migrated to the islands and began adapting to their environment through natural selection.

Carbon compounds make up most of the materials used in clothing, such as natural and synthetic textiles and leather, and almost all of the interior surfaces in the built environment other than glass, stone and metal.

Almost all of the natural environment has been destroyed by conversion to agriculture and logging for firewood, as well as natural soil erosion, all of which has threatened several species of birds and reptiles.

A disaster is a natural or man-made ( or technological ) hazard resulting in an event of substantial extent causing significant physical damage or destruction, loss of life, or drastic change to the environment.

A natural disaster is a consequence when a natural hazard affects humans and / or the built environment.

For example, while burning an area of fairly thick forest and thus turning it into a more open, grassy environment might reduce the viability of a large browser ( an animal that eats leaves and shoots rather than grasses ), the reverse could also be true: removing the browsing animals ( by eating them, or by any other means ) within a few years produces a very thick undergrowth which, when a fire eventually starts through natural causes ( as fires tend to do every few hundred years ), burns with greater than usual ferocity.

Ecology ( from, " house ";-λογία, " study of ") is the scientific study of the relationships that living organisms have with each other and with their natural environment.

Ecology is not synonymous with environment, environmentalism, natural history, or environmental science.

This core curriculum involves such areas that include the study of the surrounding environment, basic natural laws, and the disciplines that promote a happier, more educated living.

Environmental law is a complex and interlocking body of international treaties ( conventions ), statutes, regulations, and common law or national legislation ( where applicable ) that operates to regulate the interaction of humanity and the natural environment, toward the purpose of reducing the impacts of human activity.

Pollution control laws generally are intended ( often with varying degrees of emphasis ) to protect and preserve both the natural environment and human health.

The recognition that the natural environment was fragile and in need of special legal protections, the translation of that recognition into legal structures, and the development of those structures into a larger body of " environmental law " did not occur until about the 1960s.
