A friend used vies on R. clamitans (presented at SSAR) without success. It seems the dye moved around beneath the skin which made it difficult to relocate. his study was behavioral, so he tried to avoid excessive handling of the animals. this may not be a problem for you.
: I will soon begin my masters thesis work on the species composition and richness, diversity and habitat use of amphibians in some mitigated wetlands. My study will involve mark and recapture using all the standard amphibian monitoring techniques including funnel & pitfall traps with and without drift fences, artificial cover objects, dipnetting, seine netting, frog call surveys and opportunistic sampling. : The literature available has convinced me that using visual implant elastomers is the safest way to mark amphibians. This involves injecting a biocompatible elastomer just under the skin of the ventral surface. A UV light is then used to illuminate the markings whose color and position on the body is specific to a code that allows you to track the animal. : I have already reviewed articles by T. M. Davis and K. Ovaska (2001), S. Nauwelaerts, J. Coeck, and P. Aerts (2000), and M. Schlaepfer (1998). I was curious if anyone knew of more literature on this technique, as well as more details and tips to make it more effective and to keep the elastomer from polymerizing in the field. Also, if someone could explain the units Northwest Marine puts the VIE in ($240/4000?) that would be great. Basically, any pertinent information regarding VIEs would be appreciated! : http://www.nmt-inc.com/Products/VIE/vie.html :
