I have to do online research on an endangered or impacted species in my area. I chose the spotted dusky salamander. Here are the questions: 1- describe the natural environment of the species in terms of abiotic and biotic factors.

2- describe the biome in which the species lives and the properties of the biome.

3-if humans have altered the natural environment, describe the changes made by humans and their impact on the species.

4-choose from three types of scientific workers (biologists, chemists, and geographer’s) that you think could help solve the problems associated with this species, and explain how they could apply their knowledge.

The negative impacts of nonnative species generally outweigh the positive impacts
