Amphibians and reptiles an introduction to their natural history and conservation
This is a revision and update of a book originally published in 2002 by Linnet Press. Much has happened in amphibian and reptile conservation since then. Some major changes and additions in this revision include: A new chapter focusing on the key roles that amphibians and reptiles play in aquatic and terrestrial ecosystems. A new chapter addressing the parasitic fungus, Bd, that is attacking and killing amphibians on every continent where amphibians occur. The addition of new or expanded information, using amphibians and reptiles as examples, that ties in with key science concepts taught in grades 5-8. For example: A Structure and function. Gills, lungs, skin, mucous glands, Jacobsonís organ, vertebrae, scutes, shell, tail, feet. Reproduction and heredity. Oviparity versus viviparity. Metamorphosis, direct development.

Effects of global warming. Food chains and food webs. Interactions of organisms within ecosystems. Change in one species affects many. Effects of non-native species. Role in ecosystem changes with life cycle. Effect of environmental pollution. Threatened and endangered species. Human-caused current extinction. A Diversity and adaptations of organisms.
