What Is Interspecific Competition?

An invasive species is a species that comes out of its natural environment, and enters another. These animals are usually very bad for the ecosystem and may cause an unbalance. These animals usually come in with many competitive advantages and can easily dominate any competition. This will give them the ability to eat as much as they would like without being threatened in any way. This could possibly diminish many populations and end an entire ecosystem.

Foreign nationals bring with them the tastes and delights from their own country. Presently, Americans have such a wide selection of foods to choose from including but not limited to Mexican, Chinese, Italian, Greek, Thai, and Japanese. In the agricultural industry, researchers have taken domestic plants and bred them with international plants to create a more desirable embryonic plant which grows to have only the best characteristics of the two plants. This idealistic technology wouldn't have been deemed possible if it wasn't subject to the vast array of cultural diversity to challenge the standard characteristics of domestic vegetations.

In this Virtual Lab, one of the introduced species that didn’t become a problem to the area or pose a threat to the ecosystem or biodiversity had been the tulips owing to that it wasn’t really all that invasive. This is in view of the fact that the ecosystem of this gardener’s backyard does not likely support or voles overpowering

Different characteristics of species allows for the types of niches that can be occupied and whether or not they can be coexisted for example a food specialist will have anatomical and physiological adaptations that allow it to acquire and extract energy and nutrients from one food source extremely well, but will be at a disadvantage if that food source runs low. A food generalist may not acquire as much energy from the specialist’s preferred food, but will be able to make up for that by consuming other kinds of food. We can easily envision circumstances in which either species might outcompete the other. To achieve coexistence of species the carrying capacities of certain species must not be overshot and remain

Invasive species make bad situations into worse situations. Having a species from a different ecosystem makes them invasive species. Such as a toad or even bacteria being in another ecosystem other than their natural habitat.

Another invasive species are the Nutria. The Nutria comes from South America. It is not exactly clear

This experiment was performed to give a better idea of interspecific competition and intraspecific competition between radish seeds and wheat seeds at high and low densities. By planting two species only pots and two combined species pots our results showed that the radish seeds performed better at both interspecific and intraspecific competitions and concluded that the lower the pot density the more resources and growth. 32 radish seeds were evenly planted in pot A1 followed by 32 wheat seeds planted in pot A2 and 16 of each radish and wheat seeds combined (32 total) planted in pot AB1. We repeated this procedure again but this time planting 96 radish seeds evenly in pot A2, 96 wheat seeds in pot B2 and 48 of each radish and wheat seeds combined (96

Research Strategy: In order to back my idea I will find several informed and scholarly articles, backing my theory. This includes looking at the effects invasive species have on the native ones. I will look at both sides to accurately come to the final conclusion. The most accurate information will come from books published on invasive species. These books can be found at local libraries and online libraries.

Extinction: Most species become extinct because they can’t cope with the environmental change, and also because of introduced species that turned into competitors for

According to Silent Spring, the United States Office of Plant Introduction has introduced about 200,000 species of plants from around the world, and almost half of the 180 major insect enemies of plants are accidental imports. According to Campbell’s Biology Textbook, these imported animals are known as invasive species, organisms that become established outside their native range. Carson states that often when a species is brought to an area they are not native to, the lack of natural enemies causes the species to become dominant and extremely abundant. These invasions are likely to be permanent, however as a way to “buy time” humans have turned to quarantine and massive chemical campaigns, instead of trying to prevent new invasions. As Carson continuously stresses chemical use can have unwanted consequences and she urges people to use the basic knowledge of animal populations and their relations to their surroundings and other species to prevent them from becoming overly dominate. For example, according to Campbell’s textbook, higher diversity communities are more often resistant to invasive species because the species is less likely to dominate over the native species. This was proven by scientists working in Long Island Sounds off the Coast of Connecticut created communities of different diversity consisting of sessile marine invertebrates, and examined how vulnerable the experimental communities were to an invasive species: the exontic tunicate. They found the tunicate was four times more likely to survive in lower diversity communities than higher diversity communities. It was concluded the diverse communities captured more of the resources available, leaving fewer resources for the invader. It is firmly believed by Carson that people should do much more simple research before transferring a foreign species to a new habitat to not only prevent a

Biodiversity boots ecosystem productivity where every little species plays an important role in maintaining a healthy community. Maintaining a viable habitat requires lots of efforts, determination and frequency. Invasive plants are a major threat to our natural environment. These invasions change the natural diversity and balance of ecological communities. They threaten the survival of many plants and animals. They are excellent at surviving and reproducing which out-compete the native plants. Understanding these huge consequences let us understand why volunteer activities like this are so helpful and needed. They play a huge part in contributing to our environment in many positive ways. Removing these invasive plants are helping a lot in restoring the habitat and giving native plants greater chance for survival. As time went by, these efforts will slowly help cleaning our atmosphere, providing our environment with fresh air and improve health effects in human (Sagoff,

An example of an invasive species is “Cane Toad.” The cane toad was supposed to get rid of sugar cane pest, but then it came a pest. It only has a few predators outside from where it lives.But when animals try to eat it a discharge of poison goes on it’s skin and the predator gets poisoned and dies in a few minutes.Also it has been released into out of zoos on purpose.The cane toad used to live in South America and mainland middle of America, now it has been moved to Oceania and the Caribbean also North Australia.What people do is they eat toad and make soup of their eggs but this ends up killing them.

An example of an invasive plant includes the Canada thistle. The Canada thistle harms the environment because it, “crowds out and replaces native plants, changes the structure and species composition of natural plant communities and reduces plant and animal diversity… prevents the coexistence of other plant species through shading, competition for soil resources… through the release of chemical toxins poisonous to other plants” (Canada). The Canada thistle’s only special way of harming the surrounding environment consists of poisoning the plants that surround it. Otherwise the Canada thistle does not have any special ways that it harms the environment. People brought the Canada thistle to the United States in the 1600’s. By the year 1954, Canada and the United States of America declare the Canada thistle as a “noxious weed.” However now many consider the Canada thistle as an invasive plant (Canada). The Canada thistle has many ways that you can control it. You can cut it by hand, pull the plant out, burn them, or use chemicals to kill these plants. The best way to get rid of the Canada thistle encompasses using chemicals. If you do not have any chemicals to do this job you can always cut the plant down to the ground, and when it regrows do this again until the roots become exhausted

Influence on ecosystems range from human causes like the bulldozing of a forest to natural causes like a fire or a flood.  In recent times, the introduction and spread of invasive species has transformed native communities rapidly and, in some cases, created irreversible damages.  In the Earth’s history, changes have often occurred in the ecosystems.  For example, glaciers and the retreat of glaciers cause wide-spread changes.  However, although change is a constant in ecosystems, animals and habitats often cannot adapt to the rapid alterations of non-natural stresses.  Harm to the environment from the introduction of invasive species occurs through changes in the habitat and declines in the native species.  Invasive species

The biodiversity effects of non-native invasive species have been described as “immense, insidious and usually irreversible” (Veitch and Clout, 2002). There is significant evidence proving that invasive species can cause severe economic, environmental and ecological damage (Mack et al., 2000). A lot of time and research has been devoted to dividing the world into regions with distinctive habitats and species. Numerous pathways, mostly anthropogenic, are breaking down these realms and facilitating the ecological and biological invasion of non-native species.
