habitat

Examples of habitat in the following topics:

• Marine Habitats

  • Marine habitats can be divided into coastal and open ocean habitats.
  • Alternatively, marine habitats can be divided into pelagic and demersal habitats.
  • Demersal habitats are near or on the bottom of the ocean.
  • Marine habitats can be modified by their inhabitants.
  • Coral reefs provide marine habitats for tube sponges, which in turn become marine habitats for fishes.

• Habitat Loss and Sustainability

  • Through increased adoption of sustainable practices, we can reduce habitat loss and its consequences.
  • Habitat loss is a process of environmental change in which a natural habitat is rendered functionally unable to support the species present.
  • Clearing habitats for agriculture, for example, is the principal cause of habitat destruction.
  • Other important causes of habitat destruction include mining, logging, and urban sprawl.
  • Describe the effects of habitat loss to biodiversity and concept of sustainability

• Climate Change and Biodiversity

  • The global warming trend is recognized as a major biodiversity threat, especially when combined with other threats such as habitat loss.
  • Scientists do agree, however, that climate change will alter regional climates, including rainfall and snowfall patterns, making habitats less hospitable to the species living in them.
  • The warming trend will shift colder climates toward the north and south poles, forcing species to move with their adapted climate norms while facing habitat gaps along the way.
  • Climate gradients will also move up mountains, eventually crowding species higher in altitude and eliminating the habitat for those species adapted to the highest elevations.
  • As a result, grizzly bear habitat now overlaps polar bear (Ursus maritimus) habitat.

• What constitutes a biome?

  • A biome consists of all the habitats of a community that make up similar ecosystems in a particular region.
  • Populations live together in habitats, which together make up a community.
  • A biome is a community on a global scale, where habitats flank each other, and is usually defined by the temperature, precipitation, and types of plants and animals that inhabit it.

• Present-Time Extinctions

  • This species was hunted and suffered from habitat loss through the clearing of forests for farmland.
  • This species, once common in the eastern United States, was a victim of habitat loss and hunting as well.
  • This phenomenon has also been shown to hold true in other habitats as well.
  • Estimates of extinction rates based on habitat loss and species-area relationships have suggested that with about 90 percent habitat loss an expected 50 percent of species would become extinct.
  • As habitat is lost, the number of species present will decrease.

• Ecological Restoration

  • The species within them will migrate to higher latitudes as the habitat of the preserve becomes less favorable.
  • Habitat restoration holds considerable promise as a mechanism for restoring and maintaining biodiversity.
  • In this habitat, the wolf is a keystone species: it is a species that is instrumental in maintaining diversity in an ecosystem.
  • The seedlings decreased erosion and provided shading to the creek, which improved fish habitat.
  • A new colony of (d) beaver may also have benefited from the habitat change.

• Fungi Habitat, Decomposition, and Recycling

  • They colonize most habitats on earth, preferring dark, moist conditions.
  • Trace elements present in low amounts in many habitats are essential for growth, but would remain tied up in rotting organic matter if fungi and bacteria did not return them to the environment via their metabolic activity.
  • As saprobes, fungi help maintain a sustainable ecosystem for the animals and plants that share the same habitat.

• Habitats and Energy Metabolism of Crenarchaeota

  • Crenarchaeota exist in a wide range of habitats and exhibit a great variety of chemical reactions in their metabolism.
  • Archaea exist in a broad range of habitats, and as a major part of global ecosystems, they may contribute up to 20% of earth's biomass.
  • Other common habitats include very cold habitats and highly saline, acidic, or alkaline water.

• Seedless Vascular Plants

  • With these advantages, plants increased in height and size and were able to spread to all habitats.
  • The spores are very lightweight (unlike many seeds), which allows for their easy dispersion in the wind and for the plants to spread to new habitats.
  • Although seedless vascular plants have evolved to spread to all types of habitats, they still depend on water during fertilization, as the sperm must swim on a layer of moisture to reach the egg.

• Ecology, Epidemiology, and Evolution of Pathogens

  • Ecological competence is the ability of an organism, often a pathogen, to survive and compete in new habitats.
  • When that happens, a pathogen that had been confined to a remote habitat has a wider distribution and possibly, a new host organism.
  • Several human activities have led to the emergence and spread of new diseases, such as encroachment on wildlife habitats, changes in agriculture, the destruction of rain forests, uncontrolled urbanization, modern transport.
  • However, the host, being the parasite's resource and habitat in a way, suffers from this higher virulence.
