Recommended: Understanding ecological niche

A niche is a position or role taken by a kind of organism within its community. Such a position may be occupied by different organisms in different localities. Over time, animals have evolved through natural selection to their physical structures, physiology, and behavior to survive. These changes have helped determine the niche in which an animal is placed. It is impossible for two different species to have the same niche. The determinacy of a niche consists of three components: dispersal of ability—how well individuals or their offspring can move from place to place—tolerance to different environmental conditions, and interactions with other niches. An organism with high dispersal ability may not be affected as much by spatial structure.

    In 1927, Charles Elton took niche theory a step further and included food. He defined the niche of an animal as its place in the biotic environment and its relations to food and enemies (Elton, 1927). Grinnell also wondered if food was a limiting factor to the California Thrasher’s niche, but since the bird is omnivorous, it could find food in other habitats such as a forest floor or a meadow. There had to be other factors that restricted the bird to the chaparral bushes (Grinnel, 1917). Elton believes that the niche of an animal can be defined by its size and its food habits. It is important to study niches because it enables ecologists to see how different animal communities may resemble each other in the essentials of organization (Elton, 1927). For example, in a forest there could be a niche of owls that feeds on small animals such as rats. This same carnivore niche is filled with kestrels in the open grasslands. This carnivore niche is then dependent on the small animals in the herbivore niche (Elton, 1927). Hutchinson also discusses niche theory in his “Concluding Remarks” paper. His theory seems to combine some of the ideas

  • Comparative Study of Texas and Minnesota Ecosystems

    929 Words  | 2 Pages

    What is a biome? Biomes are major life zones characterized by vegetation type or by the physical environment. Climate plays a role in determining the nature and location of Earth’s biomes. Texas has 10 different ecosystems with lots of diversity. Minnesota has 4 different ecosystems which are also quite diverse. Regardless of the size of the biomes or the number of biomes in each state, they are all important not just to the locate environment but on a global level because of the life they support. We are going to take a look at the different biomes, comparing climate and rainfall, as well as vegetation fauna.

  • Adverse Impacts of Landscape Fragmentation on Biodiversity

    2246 Words  | 5 Pages

    Biodiversity is influenced by landscape fragmentation at various scales of space and time. The extinction of ecosystem types and component species may cause an increased patchiness of the landscape, resulting in lower population sizes and decreased connectivity. As a result, inhabitants may experience decreased dispersal abilities and lowered gene flows between populations.

  • Understand Adpation's Role In Selection

    213 Words  | 1 Pages

    to understand adpation's role in selection, we have to first understand how adaption is driven. Adaptions is driven by physical conditions and biological conditions. Terrain, weather, and climate are all examples of physical conditions that an animal must adapt to in order to survive. That's not all, animals are also driven to change and evolution by surrounding prey and predators. A prime example of this is the battle between newts, specifically toxic newts, and Garter snakes. Some newts are very toxic, and if eaten could kill hundreds of any of it's predators, except for one. The Garter snake has built up a resistance to toxic newts, and while eating them affects them, it doesn't kill them. In exchange for this resistance, the Garter snakes

    ... but similar areas. They put some in isolation and some went into a mixture of other species. It was discovered that the species in the mixture evolved more diversely than those that were in isolation. They also discovered that the mixture of species changed the way they used resources. This showed that the species that evolved together were more productive than the species in isolation. The final conclusion was that “species interactions can have a major effect on evolutionary dynamics, which can in turn influence ecosystems functioning” (Timothy G Barraclough).

    On the first level, when foreign, but previously non-invasive species is first introduced to a new area, the new species may play a role in a community that was previously unfulfilled; it may fill a vacant niche in the ecosystem. Originally this new species may be seen as a useful contributor to its new surroundings because it has only (temporarily) increased biodiversity in the area (Meinesz, 2003).

  • Ecology and the Biosphere

    1158 Words  | 3 Pages

    Ecology is a complex and extremly large subject because ecology has to deal with different parts of Biology and connections to many other subjects, such as Earth Science, Natural History, and Biology. We know for a fact that Natural History helps back up Ecology because it gives it an insight on what happened with the enviorment and how the animals behaved. But how are Biology and Ecology relative to each other? Well, due to Charles Darwins theory of distrubition of organisms and their adaptation to specific environments lead to prove that environmental factors interacting with variation within populations could cause evolutionary changes within the specific species. For example, if we take a coyote and a rabbit or a hawk and a mouse there would be a strong impact on the prey population which would lead to evolutionary changes w...

  • ENVIRONMENTAL POLLUTION

    1653 Words  | 4 Pages

    The branch of science that deals with how living things, including humans, are related to their surroundings is called ecology . The Earth supports some 5 million species of plants, animals, and microorganisms. These interact and influence their surroundings, forming a vast network of interrelated environmental systems called ecosystems. The arctic tundra is an ecosystem and so is a Brazilian rain forest. The islands of Hawaii are a relatively isolated ecosystem. If left undisturbed, natural environmental systems tend to achieve balance or stability among the various species of plants and animals. Complex ecosystems are able to compensate for changes caused by weather or intrusions from migrating animals and are therefore usually said to be more stable than simple ecosystems. A field of corn has only one dominant species, the corn plant, and is a very simple ecosystem. It is easily destroyed by drought, insects, disease, or overuse. A forest may remain relatively unchanged by weather that would destroy a nearby field of corn, because the forest is characterized by greater diversity of plants and animals. Its complexity gives it stability.

  • The Importance of Seed Dispersal

    ...s. There would be severe overcrowding if they just fell where the parent plant is located meaning that the seeds would not get enough sunlight, water or space to grow and develop properly. If all members of a species were to be crowded together in one area it would make them more susceptible to risks such as fire or disease. By the dispersal of the seeds covering a wider area the chance of this happening would be greatly reduced (11). There for seed dispersal is necessary to help ensure as many seeds as possible have a chance to grow and develop properly, so that they are able to then develop seeds of their own (8). The loss of herbivores such as the wild ox (bos primigenius) in the Caledonian forest has deprived that area of an important dispersal agent but there are still other herbivores such as rodents that can still help maintain the dispersal of seeds (11).
