Book review – Notes from Deep Time: A Journey Through Our Past and Future Worlds

6-minute read

Deep time is, to me, one of the most awe-inspiring concepts to come out of the earth sciences. Getting to grips with the incomprehensibly vast stretches of time over which geological processes play out is not easy. We are, in the words of geologist Marcia Bjornerud, naturally chronophobic. In Notes from Deep Time, author Helen Gordon presents a diverse and fascinating collection of essay-length chapters that give 16 different answers to the question: “What do we talk about when we talk about deep time?” This is one of those books whose title is very appropriate.

Book review – Finding the Mother Tree: Uncovering the Wisdom and Intelligence of the Forest

8-minute read

The idea that trees communicate and exchange nutrients with each other via underground networks of fungi has captured the popular imagination, helped along by the incredibly catchy metaphor of a “wood-wide web”. Suzanne Simard, a Professor of Forest Ecology at the University of British Columbia, has developed this idea more than anyone else and happily talks of mother trees nurturing their offspring. This idea has not been without controversy in scientific circles, if only for its anthropomorphic language. I was both sceptical and curious about her ideas. High time, therefore, to give her scientific memoir Finding the Mother Tree a close reading.

Book review – Mammalian Paleoecology: Using the Past to Study the Present

7-minute read

Scottish geologist Charles Lyell quipped that the present is the key to the past. To say that the reverse also holds is more than just circular reasoning. Felisa Smith, a professor in ecology and evolutionary biology, studies extinct mammals and applies this knowledge to the present. This book is a neatly crafted package that gives the reader all the required background knowledge, while its case studies make for fascinating reading. (Spoiler alert: packrat middens are my new favourite discovery.)
