Adoption Rules: choose an animal from the local surroundings which has not been adopted yet; create the best possible card-file on the Web with at least one good photograph of the species which is free of copyrights; find as scientific advisor an expert on the species and find also a good linguistic corrector; commit to act as experts about incoming questions and continually correct and update the card-file.

31. What an excellent question! The answer actually has three parts: 1. females do not breed every year 2. males remain in the ponds for a longer time than the females 3. males often breed at an earlier age. Therefore, on any single night of the breeding season, most of the males of the population are present in the pond and the females can be divided into four categories: - mature females, breeding this year, present in pond - mature females, breeding this year, not yet in pond - mature females, not breeding this year - immature females Pete Ducey Department of Biological Sciences SUNY at Cortland, Cortland, NY 13045 www.cortland.edu/herp/ De : Pete Ducey À : Claude’s Class Date : 5 may, 1999 12:35 Objet : Re: Question from the class...

33. > Q1- Could it be that there are more spots on regenerated tails? Although I don’t know of any published work on this subject, it does seem indeed that that there is a larger number of spots on regenerated members in Spotted Salamanders, not only in the case of the tail, but also for any of the four legs. This conclusion stems from personal as well as colleagues’ observations. But these data have not been scientifically validated yet, and it remains hard to explain why the regenerated colored spots would come out more numerous. It might be some kind of artifact resulting from the way the color pigments are assembled when new tissue gets formed in the regenerated member...
