[EX Q]: Lonely Planet Mexico . Excellent book full of useful advice about travelling in Mexico. Really helped me to get an insight into the country and where i would like to visit while i'm there.
[EX A]: POS

[EX Q]: Save your money . I thought this book would provide more insight on kitchen appliances and ways to downsize but cook different meals. The recipes were awful in my opinion and I would not want to eat them even at home, much less on the open road. A few good hints but not at the price of buying the book brand new
[EX A]: NEG

[EX Q]: scientists are human, science is not ahistorical... . Kingsland is biology by training therefore many scientific concepts in this book are very welled summarized and organized, making it easy for professionals and non-professional as well to grasp the general ideas in population biology. However, this book focus more on the historical context and the personality of some key scientists in this area, which gives readers more indepth understanding outside science itself. The auther did a wonderful job in interweaving science and human sides, and made it easy to pick up some major transitions in the history of population biology. highly recommmended to professional population ecologists, and general public who is interested in science as well! a bonus: some pictures of famous scientists in this area, such as McArthur, Lokta, Volttera etc...it's interesting to me, after reading all their work, finally had a chance to see what they look like
[EX A]:
