Our methods

Evolution Ecology Ltd uses numerous methods and techniques to provide accurate ecological information.




The Bat-corder is the worldwide first data recorder that distinguishes bat calls from other sound sources in real-time (online signal analysis). Calls are recorded digitally as call sequence. Thus, bat calls can easily be sampled automatically at nearly every possible location. Bush crickets and other sounds, wind, water, rustling of leafs etc. are, under most circumstances, not recorded at all.
