4.0 out of 5 stars
A well researched and elegantly presented nature study.,
By A Customer
This review is from: Made for Each Other: A Symbiosis of Birds and Pines (Paperback)
Ronald Lanner is a professor of Forest Resources at Utah State University. He became fascinated with the ecology of the whitebark pine, the only member of the "stone pine" family in North America, commonly found in high elevations. Its wide distribution, and that of the other stone pines was puzzling, because they tended to have large pinecones that did not open by themselves, and their seeds were large and wingless, and could not be distributed by the wind. Clearly some other agent was responsible for the way these trees would appear in fire ravaged areas, and at very high elevations. But what?Lanner concludes that Clark's Nutcracker, and related birds around the world, were and still are the instruments of these trees distribution throughout the northern hemisphere, and that this might well be a case of co-evolution; two entirely different species (in this case of two entirely different kingdoms of life), adapting to fill each others needs, to the ben! efit of both. This is a short and well argued analysis of this relationship, clearly and entertainingly written. Lanner draws not just on his own work, but on the studies of many other scientists and field researchers, and it is one of the hallmarks of his book that he describes their research in some detail, giving you a feel for how science works, with seemingly unconnected studies of plants and wildlife around the world being put together in an increasingly coherent answer to Lanner's original question. It is impeccably scientific, but not dry in the least. Lanner concludes, as almost any student of nature has to do in this era, with a warning that this beautiful relationship between birds and trees is endangered from several quarters, most notably a virulent man-introduced fungus that is devastating the whitebark pine, and thus also endangering the future of the creatures that depend on it. The book has color photographs and is elegantly illustrated. As is the cas! e with any really well done book of this kind, you feel as ! if you have learned about a lot more than just the specific topic at hand. The book is really about interdependence--how different life forms, over time, create a network of relationships, so that removing any piece of the puzzle disrupts the whole. It's one thing to hear this line endlessly parroted in the media; it's another thing to have the intricacy and beauty of such an ecosystem laid out before you. My only quibble is the title--I like it, but as a birder, would have preferred "The Nutcracker Suite." Oh well. (g)

A delightful book but with physical problems,

This review is from: Made for Each Other: A Symbiosis of Birds and Pines (Paperback)
I have no problem with the review presented by "A Reader" but the paperback version of the book presents some physical problems. First, the illustrations are not in color and would, in fact, be considered poorly done if they were printed on newsprint. This detracts significantly from the pleasure of reading the book. Secondly, a number of pages display small areas of missing ink. The resulting dropped characters are quite annoying. There apparently is a cloth edition (at least the ISBN is shown) and that may be the source of the previous review.

Pas de Deux of Evolution,
By Giordano Bruno (Wherever I am, I am.) - See all my reviews (HALL OF FAME REVIEWER) (TOP 1000 REVIEWER)
This review is from: Made for Each Other: A Symbiosis of Birds and Pines (Paperback)
The stars of this balletic study are the whitebark pine and Clark's "Crow" (as in Lewis and Clark, who reported seeing the bird). The tree needs the bird to crack open its cones, fly off with the seeds and cache them by burying, forget the location of just a few, and thus effectively spread the species. The bird needs the tree as a reliable source of food which no other species can compete for.
Advocates of "Intelligent Design" might rush to declare such symbiosis to be evidence of their pet notion; obviously neither the bird nor the tree could have come first, or formulated such a strategy of cooperation, so they must literally have been "made for each other." Author Ronald Lanner presents quite a different story, one of co-evolution over generations of bird and tree, by which the two species in a sense 'made each other. It's a striking example of Darwin's "descent with modification" and also one of a self-sustaining ecological balance that is easily disrupted by human intrusion and stupidity. Co-evolution is an important element in the Darwinian explanation of evolutionary processes. It is, I'd say, implicit in Darwin's own hypothesis, but it has needed an explicit account like this. Lanner's evidence is coherent and cogently presented. This is a book of science. But it is also wonderfully well-written and amusing to read, almost a detective novel in its unraveling of the mystery of the whitebark pine's survival. The bird, Clark's Nutcracker as it is more appropriately called now, is a delightful character. I've watched 'him' in the wild. I would hope my grandchildren (and yours) will some day have a chance to watch him also, but given that the whitebark pine is a species of high elevation, immediately threatened by warming climate, the prognosis is grim.
