Available in PDF, EPUB and Kindle. Book excerpt: The Colorado River had one of the most unique fish communities in the world. Seventy-five percent of those species were found nowhere else in the world. Settlement of the lower basin brought dramatic change to both the river and its native fish. Those changes began more than 120 years ago as settlers began stocking nonnative fishes. By 1930, nonnative fish had spread throughout the lower basin and replaced native communities. All resemblance of historic river conditions faded with the construction of Hoover Dam in 1935 and other large water development projects. Today, few remember what the Colorado River was really like. Seven of the nine mainstream fishes are now Federally-protected as endangered. Federal and state agencies are attempting to recover these fish. However, progress has been frustrated due to the severity of human impact. This report represents testimony, old descriptions, and photographs describing the changes that have taken place in hopes that it will provide managers, biologists, and the interested public a better appreciation of the environment that shaped these unique fish.

Download or read book The Close Encounters Man written by Mark O'Connell and published by HarperCollins. This book was released on 2017-06-13 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: The wildly entertaining and eye-opening biography of J. Allen Hynek, the astronomer who invented the concept of "Close Encounters" with alien life, inspired Steven Spielberg’s blockbuster classic science fiction epic film and is the subject of History Channel's Project Blue Book, and made an entire nation want to believe in UFOs. In June 1947, private pilot Kenneth Arnold looked out his cockpit window and saw a group of nine silvery crescents weaving between the peaks of the Cascade Mountains at an estimated 1,200 miles an hour. The media, the military, and the scientific community—led by J. Allen Hynek, an astronomer hired by the Air Force—debunked this and many other Unidentified Flying Object sightings reported across the country. But after years of denials, Hynek made a shocking pronouncement: UFOs are real. Thirty years after his death, Hynek’s agonizing transformation from skepticism to true believer remains one of the great misunderstood stories of science. In this definitive biography, Mark O'Connell reveals for the first time how Hynek’s work both as a celebrated astronomer and as the U. S. Air Force’s go-to UFO expert for nearly twenty years stretched the boundaries of modern science, laid the groundwork for acceptance of the possibility of UFOs, and was the basis of the hit film Close Encounters of the Third Kind. With unprecedented access to Hynek’s personal and professional files, O’Connell smashes conventional wisdom to reveal the intriguing man and scientist beneath the legend. Tracing Hynek’s career, O'Connell examines Hynek’s often-ignored work as a professional astronomer to create a complete portrait of a groundbreaking enthusiast who became an American cult icon and transformed the way we see our world and our universe.

Download or read book Adventures among Ants written by Mark W. Moffett and published by Univ of California Press. This book was released on 2010-05-05 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: Intrepid international explorer, biologist, and photographer Mark W. Moffett, "the Indiana Jones of entomology," takes us around the globe on a strange and colorful journey in search of the hidden world of ants. In tales from Nigeria, Indonesia, the Amazon, Australia, California, and elsewhere, Moffett recounts his entomological exploits and provides fascinating details on how ants live and how they dominate their ecosystems through strikingly human behaviors, yet at a different scale and a faster tempo. Moffett’s spectacular close-up photographs shrink us down to size, so that we can observe ants in familiar roles; warriors, builders, big-game hunters, and slave owners. We find them creating marketplaces and assembly lines and dealing with issues we think of as uniquely human—including hygiene, recycling, and warfare. Adventures among Ants introduces some of the world’s most awe-inspiring species and offers a startling new perspective on the limits of our own perception. • Ants are world-class road builders, handling traffic problems on thoroughfares that dwarf our highway systems in their complexity • Ants with the largest societies often deploy complicated military tactics • Some ants have evolved from hunter-gatherers into farmers, domesticating other insects and growing crops for food
