RE: Help with Paper
Try the Journal of Wildlife Management published by theWildlife Society. It will have specific research projects that yoiu can reference for your paper. I have an associates degree in wildlife management and have participated in several Whitetail research projects.
I would have to say the single most important technological advance would be radiotelemetry. Now that deer can be radio collared, scientists can determine home ranges, find carcasses to determine cause of death, determine mortality and survival rates (to a lesser extent), etc.
DNA testing is also a huge advancement in the wildlife management field. I am not sure if it is used much for deer, but I worked on a Grizzly Bear Study where DNA samples were used to determine the # of Grizzlies in the Nothern Continental Divide Ecosystem. These samples could also determine sex and some geneaology.
Sorry to ramble, good luck with the project. I would definitely suggest consulting journals.
