Which of these hypothetical species would be least impacted by climate change? An arctic seal A mid-elevation shrub in the temperate zone A coral in a tropical coral reef A wildflower found only on mountaintops An endemic orchid with a coevolved pollinator

The Endangered Species Act (ESA) of 1973 has helped to slow the destruction of habitat and the loss of species in the United States.  There are now many success stories of animals/plants that were on the edge of extinction and now are returning.  Even with the success stories there are many who criticize ESA. I want you to give at least 2 examples (with explanation) that show the success and need for The Endangered Species Act. And give 2 reasons why ESA is still criticized after all these years.

A new species of toad is introduced into a region in a shipment of fruit, survives, and manages to start breeding. How could you determine whether the toad was an invasive species? You would need to determine whether it started breeding with native species. You would have to see if it was present over a large region or if it stayed in one location. All nonnative species are invasive species. O You would need to watch over time to see if it had a negative effect on other species. As it is now breeding in the area, it would be considered native and not invasive.

Of the 50,000 species introduced into the United States, half are plants. Describe two ways in which non-native plants might be brought to a new environment. How might we help prevent non-native plants from establishing in new areas and posing threats to native communities?

More Text AnoVU combined with rising sea levels increased the presence of salt water in freshwater areas. Most bald cypress seedlings cannot survive in water with high concentrations of salt. Bald cypress trees depend on occasional forest fires to prevent other types of trees and shrubs from invading their habitat. Without these fires, other tree species would eventually take over a stand of bald cypress trees and change the ecosystem. Cypress swamps benefit people and animals; they absorb water during floods, filter waste from runoff by trapping it in plants and sediments, and provide habitats and food for many species. The diagram shows food web relationships between some of the organisms in a cypress swamp.
