Picture: The "air potato" is an example of an invasive species introduced to America by Africa in 1905. It has the ability disrupt natural processes such as fire and water flow. Summary: Invasive species are species of a certain environment that are, either intentionally or unintentionally, taken to other ecosystems by humans. Once species invades an ecosystem, it either dies out, or disrupts the natural process of the native ecosystem and species that live in it. This causes native species and invasive species to compete for survival. Ultimately, one species, usually the fitter of the two, will survive. One simple species may drastically change the native population for multiple reasons. One of which is the fact that it disrupts the natural food chain. Invasive species potentially have the power to even harm humans, through unnatural succession.
Opinion/reflection: It is amazing how much humans harm nature, in general. Countries should take species invasion more seriously. Also, humans should realize what they are doing to nature and native species by introducing invasive species.
Questions:
- If you think about it, have you ever introduced an invasive species to a native area?
- Are invasive species always bad?
- Specifically, how can humans stop this problem?
Invasive species can really cause a lot of trouble within one ecosystem.The bad part about invasive or exotic species is that humans bring them into the environments they end up in. We as humans can stop it as long as we are conscientious about not bringing invasive species into environments. It's surprising how much of an impact one species can have to a whole environment. If we just make the slightest effort not to introduce invasive species into ecosystems, we can save a whole bunch of other species.
ReplyDeleteQuestions:
1.What are some invasive species in Pennsylvania?
2. Are there invasive species in biodiversity hotspots?
3.What happens when you put two invasive species into one ecosystem?
Just putting a goldfish into a nearby pond can have undesirable results as it could be an invasive species. When I was a kid, I took a lizard that I had found in my yard, and put it into the woods, for all I know the lizard is killing all of the other organisms and reproducing at a high rate.
DeleteHumans are responible for this species destroying ecoystems. People should take responibleity for there actions. I think we should try our best to protect our biosphere from our own actions.
ReplyDeleteTo answer question 3, I think it would kill everything. The two species would battle it out to see that would be the domant force in the area, The native species would die out with the two foes taking all the food.

Invasive species are a source of much damage to many ecosystems. They provide unrealistic competition, because oftentimes the invasive species will have no natural predators in the new environment. This allows them to proliferate unchecked, and use the resources that the native species should be using to excess. They exhaust resources, and that causes s shortage for native species. Why humans introduce non-native species is unfathomable, and contemptible; but the answer may simply be ignorance.
ReplyDeleteHumans can make this problem less, through education. Those who introduce foreign species often are unaware of the effect it may have on the ecosystem. If they did know, perhaps they would not do it. We humans can prevent other humans from spreading exotic species.
invasive species are incredibly harmful to most ecosystems. their populations often grow exponentially and wipe out other species in the area. As the ones introducing these species we need to do everything in our power to eliminate these species in the areas of concern, and do what we can to prevent species from coming to a new region and becoming invasive. in response to question 3, the two species would ultimately kill each other (if they have the same food source) or drastically reduce the populations of the native species in the area (if they occupy different niches). either way, the result will NOT be good
