The study incorporates multiple environmental drivers — notably climate and fire — at large spatial scales for a significant number of species and populations. (sciencedaily.com)
So if you want to understand the average behavior of that system you need to sample at a much larger spatial scale over larger time intervals than was previously appreciated. (newscenter.lbl.gov)
Measuring noise pollution is a challenging task, given its diffusive nature and since sound is not easily monitored remotely over large spatial scales; it can't be measured by satellite or other visual observations. (sciencedaily.com)
