I agree with the comments above. Overall, the guidelines are OK, but there are some changes that need to be made, in my opinion. Further to those suggested above, you should include sections on maintaining other life-stages, such as larvae and juveniles. For breeding programmes and research populations, information on this is vital. Also, the statement that this species can be kept aquatic all year round isn't strictly true, particularly of juveniles. Some subspecies, including I. a. apuanus, mare very amenable to aquatic maintenance as juveniles PROVIDED A SMALL LAND SECTION IS AVAILABLE WITH A HIDE, whereas as others, including the nominate (I. a. alpestris, are not nearly as amenable to this and usually require at least a year of terrestrial housing. Other than for neotenic individuals, terrestrial rearing as juveniles is probably the safer bet if subspecies is unknown.
Also, I am not sure what the relevance of the heart and respiratory rate sections are...I'm not sure why its useful to have a couple of sections on just two of many physiological measures....
