Here in the Washington, D.C. area, where the BHL Secretariat is housed, North American wildlife is a hot topic with the grand opening of the new National Zoo American Trail exhibit. The exhibit features some of the most iconic American species, including the Bald Eagle, Gray Wolf, North American Beaver, and the Otter. We’ve been celebrating the exhibit all week on Twitter and Facebook, and we thought it only natural to further commemorate American fauna with our book of the week. To do so, we’ve selected Wild Animals of North America (1918), contributed by the American Museum of Natural History.

The relationship between man and cow is ancient. Evidence for domestication of cattle dates back to Mesolithic times (10,000 to 5000 BCE). For thousands of years, humans have made use of cows for labor, leather, milk, butter, cheese, meat and manure – among other things. (see diagram below) It is humbling to know that our modern society, an urbane environment seemingly so far removed from the life of a shepherd, is built on the foundation of pastoralism and animal husbandry. We are indebted to cows, who in-part have helped transform human subsistence into secure existence. In return for their contributions to mankind, cows only require that we feed, shelter, and defend them against wild animal attacks and disease. Regrettably, the commercialization of the beef industry has changed our ancient relationship with the cow dramatically for the worse.

The Biodiversity Heritage Library (BHL) has made significant contributions to the research community over the past five years.  One of the largest has been to successfully digitize a significant mass of biodiversity literature (nearly 40 million pages) and make that literature available for open access and responsible use as a part of a global “biodiversity commons.”

In the 1920s, a once-familiar face in the northwestern United States all but disappeared. The majestic gray wolf, a top predator in the Rocky Mountain ecosystem, gave way to the pressures of habitat loss and human hunting. By the 1930s, a previously healthy breeding population of wolves was extinct in Montana. While the decimation of any species is tragic, the loss of top predators can have an even more profound effect on an ecosystem.

This week, throngs of people who are amping up for Discovery Channel’s 25th annual Shark Week. This week long commemoration of all things sharks is aired in 72 countries watched by ~ 30 million viewers and is the longest running program event on cable. Every year schools of shark fans around the world countdown the days in anticipation for this late summer shark line-up and when it arrives they organize home-screening parties, play games, trivia, award prizes, shave their hair, get manicures and generally remain glued to their televisions marveling in the jawsome mystery and power of sharks.
