Biotic Communities catalogs and defines by biome, or biotic community, the region centered on Arizona, New Mexico, Sonora, Chihuahua, and Baja California Norte, plus California, Nevada, Utah, Colorado, Texas, Coahuila, Sinaloa, and Baja California Sur. Originally published in 1982 by the Boyce Thompson Southwestern Arboretum, this ambitious book is still a "must-have" for those working in natural resources management and ecological research, as well as non-specialists who wish to know more about a particular locale.

Biotic Communities is arranged by climatic formation with a short chapter for each biome describing climate, physiognomy, distribution, dominant and common plant species, and characteristic vertebrates. Subsequent chapters contain careful descriptions of zonal subdivisions. The text is supplemented with over one hundred black and white photographs illustrating almost every community type.

 

"What is it about these borderland cats which has so fired up people? Scarcity combined with beauty explains some of the appeal. So does the animal’s legendary strength and power as befits its role as the region’s top predator. The jaguar’s neotropical origins also add to its mystique...But there is something more. That such a large cat is out there somewhere...invokes the depths of our imagination. Nor does it matter one whit that the chance of any one individual actually seeing one is almost nil. The thought of such a cat’s presence is enough in itself."—from the book

In 1996 a rancher hunting mountain lions just north of the Arizona-Mexico border treed a jaguar. Instead of reaching for a rifle, the rancher went for his camera. Later that year another party photographed a jaguar in Arizona’s Baboquivari Mountains. These compelling photographs sparked public interest in jaguars and have resulted in calls for listing jaguars as an endangered species.

Borderland Jaguars documents the human-jaguar contact in the Southwest and presents jaguar folklore from both sides of the border. But the book is primarily a natural history of the jaguar, and discusses its distribution, habitats, and hunting and breeding characteristics before concluding with a section on the status and management of borderland jaguars, and a proposed conservation plan. Written in an engaging style, and replete with a wealth of photographs, Borderland Jaguars is a wonderful introduction to this elusive resident of the Southwest.

The Gila Monster spends 99% of its life underground, making encounters with this lizard extremely rare. Sightings are infrequent even for the biologists who study them. When one does stumble upon a Gila Monster, however, this slow-moving lizard is not easily forgotten. Advertised by orange-and-black coloration and followed by stories of venomous power, the Gila Monster carries a mystique like that of few other animals.

In this volume, authors David Brown and Neil Carmony dig out the tall tales, dispel the myths, and reveal the lizard’s true character. Through a collection of biological and historical facts mixed with entertaining stories, they have created an illuminating account of America’s largest and only poisonous lizard. Written in an engaging style, The Gila Monster is a fun and educational read for all who are intrigued by the Southwest and its most mysterious denizen.
