Winter is a busy time in the lab. The frogs start calling and it means that we all have to get out into the field.
For me, nothing is nicer than spending a day than getting up into the mountain and making a recording of moss frogs.
Here you see a microphone array, errected to conduct spatially explicit capture recapture. See Stevenson et al for a recent publication on this method.
