I’ll begin with the conclusion: O happy Americans, who have such caring wildlife magazines to expose the intricacies and wonders of their boon of wilderness!
Italy is maybe the richest and most diverse country in Europe for biology, but most Italians don’t even suspect it: our own nature magazines have gone out of business long ago, so no Airone will tell us how Marsican bears fare and whether lynx population thrives, ursine competition notwithstanding. Maybe more Italians have been at Yellowstone than in val Jannanghera, where wolf packs and herds of chamois range as well. But enough wistful thinking.
This special issue is a feast for the eye and food for thought as well: the history of the iconic American national park unfolds, as the concept of what a park should evolves, from Theodore Roosevelt’s times and beyond.
The interplay between herbivore populations (elk and bison the foremost) entered in detail, as well as the different roles of different trout species. Scenic views of the Grand Tetons explain how migratory routes weave together different territories. The dangers posed by grizzlies, bison and lightning are weighted.
Also geologically unique features are there: a supervolcano, that is a volcano of such brute force as not to be constrained to peek out of a rim of a tectonic plate and spurt (as most volcanoes do), but to be able to pierce the superficial crust directly from the Earth’s mantle, so creating a string of holes, one per eruption, as the crust slides above it over the millions of years.
