They have primarily been studied in open savanna habitats, which may have biased common descriptions.

Due to their role in transmitting Lyme disease, ixodid ticks, particularly I. scapularis, have been studied using geographic information systems ( GIS ), in order to develop predictive models for ideal tick habitats.

There are similar habitats to the Kimberley across the border in the Northern Territory including the valleys of the Victoria and Daly Rivers but these have been less carefully studied.

Other species pairs which consist of a well-armored marine form and a smaller, unarmored fresh water form are being studied in ponds and lakes in Southcentral Alaska that were once marine habitats such as those uplifted during the 1964 Alaska earthquake.

In his anthropogeographical researches, Cvijić studied migrations, village and town habitats, house types, material culture of population in regions under the influence of different civilizations, psychological types and varieties, folklore dress and the households.

Edge effects are a general term for the impacts of different habitats at or near the barrier where they meet, the “ edge .” They are an important factor in many habitats, especially when it comes to fragmented habitats, and are studied extensively in the field.

Many of DOC's Arbor Day activities focus on ecological restoration projects using native plants to restore habitats that have been damaged or destroyed by humans or invasive pests and weeds.

Most species show cyclical parthenogenesis, where asexual reproduction is occasionally supplemented by sexual reproduction, which produces resting eggs that allow the species to survive harsh conditions and disperse to distant habitats.

Such habitats may be promoted by heavy browsing by elephants, fires, flooding, tree-felling ( natural or by logging ) and fallowing.

In this scenario, terrestrial and marine communities were stressed by the changes in and loss of habitats.

: I was transfixed by the dioramas — lifelike representations of animals and their habitats all over the world.

Before DDT, malaria was successfully eradicated or curtailed in several tropical areas by removing or poisoning mosquito breeding grounds and larva habitats, for example by filling or applying oil to standing water.

More specifically, " habitats can be defined as regions in environmental space that are composed of multiple dimensions, each representing a biotic or abiotic environmental variable ; that is, any component or characteristic of the environment related directly ( e. g. forage biomass and quality ) or indirectly ( e. g. elevation ) to the use of a location by the animal.

The second cornerstone of the Fermi paradox is a rejoinder to the argument by scale: given intelligent life's ability to overcome scarcity, and its tendency to colonize new habitats, it seems likely that at least some civilizations would be technologically advanced, seek out new resources in space and then colonize first their own star system and subsequently the surrounding star systems.

With the decline of grasslands 12, 500 years ago, Europe experienced a massive loss of lowland habitats favoured by spotted hyenas, and a corresponding increase in mixed woodlands.

189 countries which are signatory to the Convention on Biological Diversity ( Rio Accord ) have committed to preparing a Biodiversity Action Plan, a first step at identifying specific endangered species and habitats, country by country.

Many different anthropogenic sources have helped to create this decline, including the siltation and sedimentation, blocking of dispersal / migration routes, and destruction of riverine habitats created by dams and other development, as well as pollution, disease and overharvesting for commercial and scientific purposes.

As many of these detrimental effects have done irreversible damage to hellbender populations, it is important to conserve the remaining intact populations through protecting habitats and — perhaps in places where the species was once endemic and has been extirpated — by augmenting numbers through reintroduction.

Marine habitats can be modified by their inhabitants.

* with one or several ecosystems not materially altered by human exploitation and occupation, where plant and animal species, geomorphological sites and habitats are of special scientific, educative and recreative interest or which contain a natural landscape of great beauty.

Many scientists argue that the Permian-Triassic extinction event was caused by a combination of some or all of the hypotheses above and other factors ; the formation of Pangaea decreased the number of coastal habitats and may have contributed to the extinction of many clades.

Native vegetation is largely intact as the desert is uninhabitable so habitats are not threatened by agriculture but are damaged by introduced species, particularly rabbits and feral camels.

In parapatric speciation, there is only partial separation of the zones of two diverging populations afforded by geography ; individuals of each species may come in contact or cross habitats from time to time, but reduced fitness of the heterozygote leads to selection for behaviours or mechanisms that prevent their inter-breeding.

The Engaresero village on the Western shores of Lake Natron has been chosen by the government of Tanzania to exemplify the Maasai pastoral system given its singularity, integrity, high diversity of habitats and biodiversity.

soil degradation ; deforestation ; desertification ; destruction of coral reef threatens marine habitats ; recent droughts affected marginal agriculture ; wildlife threatened by illegal hunting and trade, especially for ivory

* Cass Field Station-Provides a wide range of environments: montane grasslands, scrub, riverbed, scree, beech forest, swamp, bog, lake, stream and alpine habitats ; all accessible by day-trips on foot

Due to the changing sea levels, many different environments are represented in the Horseshoe Canyon Formation, including offshore and near-shore marine habitats and coastal habitats like lagoons, estuaries and tidal flats.

Mariculture refers to aquaculture practiced in marine environments and in underwater habitats.

They are the most common heliozoa in fresh water, and are especially frequent in lakes and rivers, but a few are found in marine and soil habitats as well.

They are found in all major habitats, except marine and the polar regions.

With the exception of benthic habitats directly beneath marine farms, most mariculture causes minimal destruction to habitats.

Most marine life is found in coastal habitats, even though the shelf area occupies only seven percent of the total ocean area.

Alternatively, marine habitats can be divided into pelagic and demersal habitats.

They are found in coastal marine and estuarine habitats, and in freshwater river systems along the west coast of Africa from the Senegal River south to the Kwanza River in Angola, including areas in Gambia, Liberia, Guinea-Bissau, Guinea, Sierra Leone, Côte d ' Ivoire, Ghana, Mali, Nigeria, Cameroon, Gabon, Republic of the Congo, and Democratic Republic of the Congo.

The San Francisco Peninsula contains a variety of habitats including estuarine, marine, oak woodland, redwood forest, coastal scrub and oak savanna.

* Kaikoura Field Station-Provides a wide range of environments: diverse marine habitats, alpine habitats, kanuka forests, rivers, lakes

This is likely an adaptation for living in marine coastal habitats.

The first tetrapods are thought to have evolved in coastal and brackish marine environments, and in shallow and swampy freshwater habitats.

Most are marine plankton, but they are common in fresh water habitats, as well.

They are common in freshwater, and also occur in marine and brackish habitats.

Compare, e. g., Claridege v. N. H. Wetlands Bd., 485 A. 2d 287, 292 ( N. H. 1984 ) ( owner may, without compensation, be barred from filling wetlands because landfilling would deprive adjacent coastal habitats and marine fisheries of ecological support ), with, e. g., Bartlett v. Zoning Comm ' n of Old Lyme, 282 A. 2d 907, 910 ( Conn. 1971 ) ( owner barred from filling tidal marshland must be compensated, despite municipality's " laudable " goal of " preserv marshlands from encroachment or destruction ").

A section of the national park extends into the sea creating fully protected land, shore and marine habitats.

They are the most genetically diverse ; they occupy a broad range of habitats across all latitudes, widespread in freshwater, marine and terrestrial ecosystems, and they are found in the most extreme niches such as hot springs, salt works, and hypersaline bays.

The word oyster is used as a common name for a number of distinct groups of bivalve molluscs which live in marine or brackish habitats.
