The New Cosmos
Astronomy, astrophysics and space research have witnessed an explosive development over the last few decades. The new observational potential offered by space stations and the availability of powerful and highly specialized computers have revealed novel aspects of the fascinating realm of galaxies, quasars, stars and planets. The present completely revised 5th edition of The New Cosmos provides ample evidence of these dramatic developments. In a concise presentation, which assumes only a modest prior knowledge of mathematics and physics, the book gives a coherent introduction to the entire field of astronomy and astrophysics. At the same time it takes into account the art of observation and the fundamental ideas behind their interpretation. Like its predecessors, this edition of The New Cosmos will provide new insight and enjoyment not only to students and researchers in the fields of astronomy, physics and earth sciences, but also to a wide range of interested amateurs.
The Solar System
In this third corrected and revised edition students and lecturers in astronomy and planetary science as well as planet observers will find a mine of up-to-date information on the solar system and its interaction with the interplanetary medium, its various objects, comparative planetology, discussion of questions for further research and future space exploration.
A History of the Southwest
Something about the Southwest draws people who are independent. From the Apaches who migrated south six hundred years ago to the Spanish exploring north Mexico not much later to the Anglo American who ventured west, these were people who wanted to live, as one Comanche leader said, "where the wind blows free and there is nothing to break the light of the sun." A History of the Southwest explores these people, their clashes with each other, with the environment, and finally with the forces of an increasingly complex economy. Thomas Sheridan takes the behavior of individuals--Geronimo, Wyatt Earp, Theodore Roosevelt--and local cultural groups--Pueblo Indians, southern European miners, ranchers--and shows how it was acted out on the lager stage of the environment, economics, and politics.

Ecology and Conservation of the Cactus Ferruginous Pygmy-owl in Arizona
This report is the result of a cooperative effort by the Rocky Mountain Research Station and the USDA Forest Service Region 3, with participation by the Arizona Game and Fish Department and the Bureau of Land Management. It assesses the state of knowledge related to the conservation status of the cactus ferruginous pygmy-owl in Arizona. The population decline of this owl has been attributed to the loss of riparian areas before and after the turn of the 20th century. Currently, the cactus ferruginous pygmy-owl is chiefly found in southern Arizona in xeroriparian vegetation and wellstructured upland desertscrub. The primary threat to the remaining pygmy-owl population appears to be continued habitat loss due to residential development. Important information gaps exist and prevent a full understanding of the current population status of the owl and its conservation needs.
