Equipment Notes: 2-channel mono. One DPA mic feeding both channels. Right channel at -10dB from left channel. NPR/NGS RADIO EXPEDITIONS Show: AZ frogs Log of DAT #: 7 Engineer: Deputy Date: July 18, 2002 Dennis Suhre head mic 1:30 heavy breathing - and walking on gravel - talking in bg 2:14 they just dug this one out w/in the last month 2:25 recently they dug this out bc I guess they didn't want it to go dry anymore - but they dug it out quite a bit - this one just filled - this is all new water w/in the last couple of days 2:38 3:00 Dennis - we are going to stand in the water and catch frogs! And that is what is going on¿they can see us if you have a light on us¿ 3:30 we are hoping that we catch something 3:46 my name is Dennis Surey. Right now we have marked several populations of frogs out here in the valley, and this tank was dry when we marked all of these frogs and it recently filled in the last couple of days so we are going to go down here and see if we can mark some frogs that we already marked so we can find out the distance that they have moved, and then calculate rain fall versus how far they will go on a certain night. 4:12 4:14 it is imp to know bc we are trying to establish a population on the refuge of native leopard frogs and the bullfrogs tend to eat the native fros so we want to find out how far away the bullfrogs need to be as a safety catch so that we can deal with the problem before they eat the native frogs. 4:32 4:40are you guys ready? - frog be with us! 4:49 walking and spitting 5:00 op! trying to make sure you don't fall 5:11 big spit 5:12 walking and breathing 5:38 ooh it is deep! (said quietly) - 5:39- 8:01 walking in water, gently, heavy breathing (looking for frogs) 6:42 spit! 7:56 spit! 8:05 Ok, so I have got a marked frog guys! I have got a marked frog 8:24 - walking out of the water - towards people - 8:35 - yeah, it is actually 8:42 so did you guys catch any? 8:50 walking out of the water 8:54 ok, well I caught 3 and got a marked one. 8:58 one marked. 9:02 I am going to remark - I am going to mark these with a specific tank bc I don't know where they came from, but we have got them now. And then I will mark the one that we caught from the other tank so that we know (Cecil - w/that same mark) well, at least a portion of that same mark so that we know that it came from one tank and ended up here - so we can track its movements when it moves to another tank. 9:22 9:32 ok, here we go. What we have got here is a - he is missing his second right front finger there, and his second left front finger there. Which means that this frog came from novio which is a tank that is probably 2 miles from here - maybe a little bit more - 2 ½ - and we had rain Tuesday night and Monday night and this frog has moved 2 ½ miles across the desert and you guys just drove across it and you have seen how barren and dry it is, and it has actually moved across the desert and come here, to a place it can now colonize bc there are no adults. 10:16 10:21 this is a juvenile bullfrog, it metamorphosed - it still has got a little tail nub on there - so we are looking at maybe 2 weeks it has had legs and a tail, so now it has absorbed all of that and it has actually gotten out of the pond and moved over here to get away from predation and other pressures from the adults. 10:47 yes. 10:59 That is why we do 2 marks so that we can make sure that it is not some random anomaly that you say you loose this finger and you are only cutting one finger off. It could be random or it could be your marked - so that is why you make 2 so that you can make sure it is an individual ... (Notes truncated)
