for species invasion what are the mechanism(s) by which invasive species overcome these barriers to immigration that exist in stable ecosystems
Step by step
Solved in 2 steps
- When it comes to species invasions what are the barriers to immigration that exist in stable ecosystemsInvasive species have the greatest impact on (small or large?) ecosystems. Why?How do we sometimes benefit from introduced species that are not invasive? Explain using examples you have witnessed or personality benefited from.
- why is it bad that there are a lot of endangered species and certain ecosystems are collapsing and from distress?What should be done about an invasive species, especially one that dominates an ecosystem or causes economic damage? Should we try to eliminate the invasive species entirely? Should we try to contain it or reduce its influence? Should we just give up and learn to live with it?Why do scientists consider invasive species to bea problem? What makes a species “invasive,” andwhat ecological effects can invasive species have?Give examples.
- How is integrated pest management (IPM) different from other forms of pest control? O IPM only supports mechanical control of pests in an area. O IPM tolerates a low number of pests in an area. O IPM favors the generation of herbicide-resistant weeds. O IPM prohibits the use of herbicides in an area. O IPM suggests the use of herbicide-resistant plants.Why is a specialist more likely to be an endangered species? because they are considered invasive species because they are more valuable on the black market because their needs are only met in a few ways because their needs can be met in many different waysThe accelerating spread of non-native species is a major component of anthropogenic global change, what characteristics of non-native species facilitate their ability to become established in novel environments and become invasive?
- What is an invasive species? Why are they destructive? What general adaptations do invasive species possess?What kind of ecosystem are exotic species especially threatening to? a. deserts b. marine ecosystems c. islands d. tropical forestsThe type of place where a species typically lives is called its _______. a. niche c. community b. habitat d. population
