Predicting geographic distributions of fishes in remote stream networks using maximum entropy modeling and landscape characterizations
The Bureau of Land Management (BLM) manages the National Petroleum Reserve - Alaska on the remote North Slope but has limited data on fish distributions on which to base leasing and management decisions. To address this, we used environmental DNA, traditional sampling, watershed landscape characteri...
