I have recently looked at two books from Oxford Universtiy Press and I can report that these books are garbage and you should not botther to purchase them or bother to read them. These books are ( Ecological and Environmental Physiology of Fishes ) and ( Ecological and Environmental Physiology of Birds ).
Starting with the bird book you plenty of physiology of kidneys, pulmonary, temperature biology and metabolism. Cardiovascualar physiology is left out and neurobiology is hardly covered at all. I think birdsong is just a few pages if any at all. I just don't see how you can call this a good book when you leave out these two subjescts. The chapter on techniques completely ignores physiology and bird behavior.
The book on fish is just as bad. Neurobiology is just 7 pages and circulatory biology is just 2 pages. Why did the authors bother to include these subjects if they hardly covered them? Again you are getting shortchanged in physiology. The chapter on techniques looks like it was written by a Genetics professor because thats what the chapter mostly addresses. The chapter on techniques does not address physiology techniques. Again I say why write a book and leave out neuorbiology and cardiovascular biology.
I know people well gripe and complain about my book reviews but read any general animal physiology book and you will get much better coverage. I think part of the problem can be traced to the new toy that physiologists like to play with. What you do is put an animal in tube or appropiate environment and measure its pulmonary variables and you can extract its temperature biology, pulmonary biology, cardiovascular biology and metabolism. The trouble with this approach is that there are better invasive or non invasive ways to measure cardiovascular biology but authors seem to ignore them and thus they shortchange cardiovascular physiology.
