Book Description
The Nebraska odonate list has 109 species in two suborders, damselflies (Zygoptera) with 47 species and dragonflies (Anisoptera) with 62 species. Nebraska had been very poorly surveyed prior to 2005 and 63 counties had fewer than 10 records. By 2017 the number of county records had nearly quadrupled, to over 3000 records, the average county total had increased from 9 to 33 and all counties had at least 21 records. An effort was made to collect data more or less uniformly from all 93 Nebraska counties. The areas with intense corn and soybean farming, eastern and southcentral areas, are low in diversity (21-30 species per county), the southeast and western half of the state are higher (31-40 species) and the northwestern and northern Sandhill counties are the richest with more than 50 species per county. The present state list of 109 species represents 12 additions since 1998. Eleven additional species have been reported from the state, but are considered invalid or have been re-identified. This paper presents a short history of odonate study in Nebraska and an analysis of the data for the 109 species recorded in Nebraska to date. Distribution maps by county are included for each identified

Book Description
Animal migration is a magnificent sight: a mile-long blanket of cranes rising from a Nebraska river and filling the sky; hundreds of thousands of wildebeests marching across the Serengeti; a blaze of orange as millions of monarch butterflies spread their wings to take flight. Nature’s great migrations have captivated countless spectators, none more so than premier ecologist David S. Wilcove. In No Way Home, his awe is palpable—as are the growing threats to migratory animals. We may be witnessing a dying phenomenon among many species. Migration has always been arduous, but today’s travelers face unprecedented dangers. Skyscrapers and cell towers lure birds and bats to untimely deaths, fences and farms block herds of antelope, salmon are caught en route between ocean and river, breeding and wintering grounds are paved over or plowed, and global warming disrupts the synchronized schedules of predators and prey. The result is a dramatic decline in the number of migrants. Wilcove guides us on their treacherous journeys, describing the barriers to migration and exploring what compels animals to keep on trekking. He also brings to life the adventures of scientists who study migrants. Often as bold as their subjects, researchers speed wildly along deserted roads to track birds soaring overhead, explore glaciers in search of frozen locusts, and outfit dragonflies with transmitters weighing less than one one-hundredth of an ounce. Scientific discoveries and advanced technologies are helping us to understand migrations better, but alone, they won’t stop sea turtles and songbirds from going the way of the bison or passenger pigeon. What’s required is the commitment and cooperation of the far-flung countries migrants cross—long before extinction is a threat. As Wilcove writes, “protecting the abundance of migration is key to protecting the glory of migration.” No Way Home offers powerful inspiration to preserve those glorious journeys.

Book Description
Yellowstone Wildlife is a natural history of the wildlife species that call Yellowstone National Park and the Greater Yellowstone Ecosystem their home. Illustrated with stunning images by renowned wildlife photographer Thomas Mangelsen, Yellowstone Wildlife describes the lives of species in the park, exploring their habitats from the Grand Tetons to Jackson Hole. From charismatic megafauna like elk, bison, wolves, bighorn sheep, and grizzly bears, to smaller mammals like bats, pikas, beavers, and otters, to some of the 279 species of birds, Johnsgard describes the behavior of animals throughout the seasons, with sections on what summer and autumn mean to the wildlife of the park, especially with the intrusion of millions of tourists each year. Enhanced by Mangelsen’s wildlife photography, Yellowstone Wildlife reveals the beauty and complexity of these species’ intertwined lives and that of Yellowstone’s greater ecosystem.

Book Description
From the rare and docile massasauga, which relies on camouflage to remain unnoticed, to the more familiar bullsnake, which defends itself by hissing loudly and vibrating its tail from an S-shaped striking position, to the eastern racer, often seen crawling at more than three miles an hour during daytime, snakes are beautiful animals with habits both fascinating and beneficial to humans. Their relatives the lizards, most of which are more easily seen and identified, exhibit similarly fascinating behavior. This colorful addition to our series of laminated guides informs both amateur and professional herpetologists about twenty-seven species of snakes and six species of lizards in the Upper Midwest states of Minnesota, Wisconsin, Illinois, Indiana, Michigan, Ohio, South Dakota, North Dakota, Kansas, Nebraska, Iowa, and Missouri. Terry VanDeWalle provides a complete description of each species, both adult and young, as well as distinguishing characteristics for thirty-two subspecies of snakes and two subspecies of lizards: length, color, head and neck patterns, scales, and so on. Also included is information about habitat preferences: forests, wet meadows, and sand prairies, for example. Most helpful for identifying snakes and lizards in the field are his comparisons of similar species and his comprehensive key. Superb photographs by Suzanne Collins of adult and, when needed for identification, young snakes and lizards make this guide the perfect companion for hikers in all kinds of environments whenever a snake ripples across your path or a lizard darts into the underbrush.

Book Description
Frogs and toads have become canaries in the coal mine when it comes to conservation, as the discovery of malformed frogs has brought increased attention to global habitat loss, declining biodiversity, and environmental pollution. Midwestern species of frogs and toads—already declining due to habitat loss from agriculture—have been greatly affected by this worldwide phenomenon. VanDeWalle includes a complete description of each species along with distinguishing characteristics for three subspecies, information about range and habitat preferences, diet, types of calls, and breeding season.

Book Description
Where the eastern and western currents of American life merge as smoothly as one river flows into another is a place called Nebraska. There we find the Platte, a river that gave sustenance to the countless migrants who once trudged westward along the Mormon and Oregon trails. We find the Sandhills, a vast region of sandy grassland that represents the largest area of dunes and the grandest and least disturbed region of mixed-grass prairies in all the Western Hemisphere. And, below it all, we find the Ogallala aquifer, the largest potential source of unpolluted water anywhere. ø These ecological treasures are all part of the nature of Nebraska. With characteristic clarity, energy, and charm, Paul A. Johnsgard guides us through Nebraska?s incredible biodiversity, introducing us to each ecosystem and the flora and fauna it sustains and inviting us to contemplate the purpose and secrets of the natural world as we consider our own roles and responsibilities in our connection with it.
