Описание: Nearly half of the known species of mammals alive today (more than 1600) are rodents or "gnawing mammals" (Nowak and Paradiso, 1983). Because the diversity of rodents in the world is essentially limitless, any monograph that included all fossil rodents would similarly be limitless.

Описание:
For generations residents from coast to coast have reported encounters with large, black, long-tailed cats. These black panthers have left a trail of dead livestock and confused witnesses in their wake. These are animals that are not supposed to exist; animals that are not recognized by science. Despite the reluctance of wildlife officials to accept the reality of these cryptid cats, anomalous tracks continue to appear, pets and farm animals continue to disappear, and sightings continue to be reported.
In this full-color book with dozens of illustrations, author Michael Mayes examines historical sightings, interviews contemporary witnesses and big cat experts, sorts through a host of intriguing photographs, and takes a close look at the potential suspects in one of America's most enduring unsolved mysteries. What are the shadow cats that haunt the woods, bottomlands, and waterways of our country? What are the black panthers of North America?

A groundbreaking guide to flower flies in North America
This is the first comprehensive field guide to the flower flies (also known as hover flies) of northeastern North America. Flower flies are, along with bees, our most important pollinators. Found in a varied range of habitats, from backyard gardens to aquatic ecosystems, these flies are often overlooked because many of their species mimic bees or wasps. Despite this, many species are distinctive and even subtly differentiated species can be accurately identified. This handy and informative guide teaches you how.
With more than 3,000 color photographs and 400 maps, this guide covers all 416 species of flower flies that occur north of Tennessee and east of the Dakotas, including the high Arctic and Greenland. Each species account provides information on size, identification, abundance, and flight time, along with notes on behavior, classification, hybridization, habitats, larvae, and more.
Summarizing the current scientific understanding of our flower fly fauna, this is an indispensable resource for anyone, amateur naturalist or scientist, interested in discovering the beauty of these insects.
- 3000+ color photos (field and museum shots)
- Multiple images per species, with arrows highlighting key field marks
- Grayscale images showing the actual size of the insect
- Range maps for each species
- Information on size, identification features, abundance, flight times, and more
Описание: "A must-have for anyone involved with mosquitoes. This is the only key that incorporates the recent changes in nomenclature and new species listings with their respective distribution."--Dennis Moore, director, Pasco County Mosquito Control District Greatly anticipated and sorely needed, this book updates the successful guide to North American mosquitoes published by the American Mosquito Control Association in 1981. It includes 12 new species that have since been added to the North American mosquito fauna, revised distribution maps of all species, and revised and completely illustrated identification keys for the adult females and fourth instar larvae of all 174 species and subspecies known to occur in North America, north of Mexico. In chapters on adult and larval morphology, the coauthors--both world-renowned in their field of taxonomy--discuss the anatomical structures mentioned in the keys and pictured on full-page plates. They provide separate generic keys for adult females and larvae and keys to the species of each genus. In addition, they show the geographical distribution of each taxon in a series of maps and include a synopsis of the occurrence of species in the states and provinces of the United States and Canada. This book's usefulness to mosquito control programs cannot be overestimated. For example, it deals with 9 exotic species that have been introduced and today successfully thrive in North America. Several are increasing their range and this book will help identify these species when they first invade an area. Because of the occurrence of mosquito-borne diseases and the widespread distribution of mosquitoes as pests to humans, professionals must know how to identify them. With its wealth of up-to-date information, this book is the only one of its kind available for specialists working on mosquito-borne diseases and in mosquito control units and for both introductory and advanced students who study entomology. Richard F. Darsie Jr. is a research entomologist at the Florida Medical Entomology Laboratory at the University of Florida. Ronald A. Ward was a medical entomologist at the Walter Reed Army Institute of Research in Washington, D.C., before his retirement.

Описание: This monograph is the first of its kind devoted entirely to the dragonfly nymphs of North America north of Mexico, the focus being accurate identification of the 330 species of Anisoptera that occur in the region. Nymphal external morphology is described and illustrated in detail, and all terms needed to navigate the dichotomous keys are defined. Species are tabulated with references that provide the most detailed, accurate descriptions for each; species that are inadequately described are so indicated. The key separating the seven families in the region contains several new characters. The families are then covered separately: Aeshnidae (13 genera), Gomphidae (17 genera), Petaluridae (2 genera), Cordulegastridae (2 genera), Macromiidae (2 genera), Corduliidae (7 genera), and Libellulidae (29 genera). Each family is further characterized, followed by a generic key. A drawing of the habitus and diagnostic details for each genus are provided, along with additional diagnostic remarks and notes on habitat and life cycle; for each genus, a map shows its geographic distribution in North America. Full-grown nymphs of all known species of each genus are keyed and diagnosed; characters that apply to earlier instars are noted. Morphological variation in character states was analyzed in order to assess the reliability of previously utilized characters and to discover new characters. Most of the characters used to distinguish all levels of taxa are illustrated; a total of 702 figures, comprising 1,800 original drawings, along with selected photographs where necessary for clarity, accompany the keys. Measurements of total length, head width, and other variables for each species are provided in tables. Difficulties with past keys and descriptions, including errors, omissions and other shortcomings, are addressed. The importance of nymph characters in helping solve generic and specific distinctions and their role in phylogenetic studies is emphasized. Methods for collecting, rearing, and preserving dragonfly nymphs and exuviae are presented. The final chapter discusses research opportunities on North American Anisoptera nymphs, including taxonomic needs, studies on structure and function, life history and microhabitat, water quality indices and conservation efforts. The habitus drawings of all genera are arranged according to family in five plates (Appendix I); although the book is intended as a lab manual, these plates conveniently allow for comparison based on nymph shape making field identification to genus possible in many cases. Appendix II contains a brief history of dragonfly nymph studies in North America. A glossary and an index to scientific names are included.
