Overall, this was an okay text. I read it not for a course but to update my personal knowledge of the subject originally gained in the 1970s and only supplemented in a piecemeal fashion.
A problem: The authors/ editors do not seem to have a consistent view of their audience, which seems a problem for a textbook. Some parts of the book are moderately challenging, requiring one to bring to active use material learned in earlier chapters; this is particularly so in the coverage of biochemistry and cytology.
Another inconsistency, not unrelated to the first, is in the rigor of the science. For example, the chapters on ecology seemed more loosely reasoned then the book's earlier chapters. My retained knowledge gained from Scientific American articles and from economics showed up gaps in these chapters.
Finally the tone was inconsistent, ranging from dispassionately descriptive to preachy.
Minor point: the glossary needs expansion. It misses terms, not common outside the field, that are used in widely separated parts of the text.
