The Animal Answer Guide
One fish, two fish, red fish, nearly thirty thousand species of fish—or fishes, as they are properly called when speaking of multiple species. This is but one of many things the authors of this fascinatingly informative book reveal in answering common and not-so-common questions about this ubiquitous group of animals. Fishes range in size from tiny gobies to the massive Ocean Sunfish, which weighs thousands of pounds. They live in just about every body of water on the planet. Ichthyologists Gene Helfman and Bruce Collette provide accurate, entertaining, and sometimes surprising answers to over 100 questions about these water dwellers, such as "How many kinds of fishes are there?" "Can fishes breathe air?" "How smart are fishes?" and "Do fishes feel pain?" They explain how bony fishes evolved, the relationship between them and sharks, and why there is so much color variation among species. Along the way we also learn about the Devils Hole Pupfish, which has the smallest range of any vertebrate in the world; Lota lota, the only freshwater fish to spawn under ice; the Candiru, a pencil-thin Amazonian catfish that lodges itself in a very personal place of male bathers and must be removed surgically; and many other curiosities. With over 100 photographs—including two full-color photo galleries—and the most up-to-date facts on the world's fishes from two premier experts, this fun book is the perfect bait for any curious naturalist, angler, or aquarist.
This book will be of particular interest to those interested in applied fields of biology, such as conservation, forestry, and wild life. The southern twelve counties of Illinois, a total of 4,355 square miles, comprise the area covered in this book. It is an area in which both northern and southern flora specimens abound. A wide variety of plant species grow in this area, and nearly 200 new plants not formerly identified with this area have been included in the listings.
Especially valuable to amateur botanists, the book is an important manual in identifying the plants that make up the native scenery of this region. Seventy-seven illustrations aid in identifying and understanding the plant communities.
Basswoods to Spurges
This is the fourth volume in The Illustrated Flora of Illinois devoted to dicotyledons, or dicot plants. Dicots are the greatest group of flowering plants, exceeding the monocotyledons, or monocots. Dicots produce a pair of seed leaves during germination while monocots produce only a single seed leaf.
This volume contains four orders and ten families of dicots. The orders included in this volume are Malvales, Urticales, Rhamnales, and Euphorbiales. Within the Malvales are the families Tiliaceae, Sterculiaceae, and Malvaceae. The families Ulmaceae, Moraceae, and Urticaceae comprise the Urticales. Rhamnaceae and Elaeagnaceae make up the Rhamnales. The Euphorbiales include only the Thymelaeceae and the Euphorbiaceae.
Flowering Rush to Rushes: Flowering Rush to Rushes
The second edition of Flowering Plants: Flowering Rush to Rushes offers new material, including a preface, seventeen new illustrations of the additional species now known from Illinois, a revised list of illustrations, and an appendix of the additions and changes since 1970 in the identification, classification, and location of the plants included in the first edition. This new edition of the first volume in the multi-volume series of The Illustrated Flora of Illinois—which provides a working reference for the identification and classification of these plant forms in the state—includes flowering rushes, arrowheads, pondweeds, naiads, duckweeds, cattails, bur reeds, spiderworts, and rushes.
In his introduction, Robert H. Mohlenbrock defines terms and procedures used in the identification and classification of this group of flowering plants referred to as monocotyledons—plants that produce upon germination a single cotyledon or seed-leaf and are often identified by their tall, slender, grass-like leaves. He outlines the life histories and morphologies of the representative monocots and illustrates the plants’ habits and frequencies in Illinois.
Geared to the amateur as well as the professional botanist, the volume includes a glossary of definitions and identification keys to classify the plants according to order, family, genus, and species. The identifying characteristics of each descending class are also given in detail. The morphology of each species is outlined along with data on frequency of occurrence, related soil and climate conditions, and history of past collections. Among the 125 illustrations are detailed sketches of the important features of each species and maps indicating the geographical locations of each species in Illinois.
Pokeweeds, Four-o'clocks, Carpetweeds, Cacti, Purslanes, Goosefoots, Pigweeds, and Pinks
Robert H. Mohlenbrock provides a definitive account of the pokeweed, four-o'clock, carpetweed, cactus, purslane, goosefoot, pigweed, and pink families in Illinois.
Flowering Plants: Pokeweeds, Four-o’clocks, Carpetweeds, Cacti, Purslanes, Goosefoots, Pigweeds, and Pinks is the fifteenth volume of the Illustrated Flora of Illinois series and the ninth devoted to dicots, or plants that have two seed-leaves, or cotyledons, upon germination. Each of the 141 plants is beautifully illustrated by Paul W. Nelson.
Nelson shows the full habitat of the plant and close-ups of various vegetative and reproductive structures that are crucial for the identification of individual species. Each illustration includes detailed drawings of the flowers, fruits, and seeds of the plant covered. Mohlenbrock provides a complete description of each species as well as a discussion of the nomenclature and habitats, and his fifty-three years of experience enable him to present little-known diagnostic features for many species. Range maps show the county distribution of each species in Illinois. Mohlenbrock includes a statement giving the overall range of each species in the United States as well as a detailed key for the identification of the species.
Flowering Plants contains many plants whose obscure flower parts make them exceedingly difficult to identify. The close-up illustrations of these parts will aid the user of the book immensely in identification of the species. Included are several species previously unknown in Illinois.
New illustrations, which include detailed drawings of the flowers, fruits, and seeds are presented for each species covered in this book. Mohlenbrock’s fifty-three years of experience enable him to present little-known diagnostic features for many species.
Willows to Mustards
This eighth volume in the comprehensive Illustrated Flora of Illinois series is the seventh volume devoted to flowering plants (the eighth volume is devoted to ferns) and the second treating dicotyledons, which include such well-known plants as roses, peas, mustards, mints, nightshades, milkweeds, and asters. The previous volume on dicots, Flowering Plants: Hollies to Loasas, was published in 1978.
In the present volume, Mohlenbrock includes three orders of vascular plants encompassing five families. The orders are Salicales and Tamaricales, of the Salicaceae and Tamaricaceae families, and Capparidales, of the Capparidaceae, Resedaceae, and Brassicaceae families. In all, 44 genera and 117 species are treated in this volume, each species illustrated in detail.
The Appendix in this second edition of Smartweeds to Hazelnuts holds fourteen new plant illustrations, new information on the descriptions and the geographical locations of plants in the first edition, and revised identification keys.
Pioneer of Heredity and Biometry
If not for the work of his half cousin Francis Galton, Charles Darwin's evolutionary theory might have met a somewhat different fate. In particular, with no direct evidence of natural selection and no convincing theory of heredity to explain it, Darwin needed a mathematical explanation of variability and heredity. Galton's work in biometry—the application of statistical methods to the biological sciences—laid the foundations for precisely that. This book offers readers a compelling portrait of Galton as the "father of biometry," tracing the development of his ideas and his accomplishments, and placing them in their scientific context. Though Michael Bulmer introduces readers to the curious facts of Galton's life—as an explorer, as a polymath and member of the Victorian intellectual aristocracy, and as a proponent of eugenics—his chief concern is with Galton's pioneering studies of heredity, in the course of which he invented the statistical tools of regression and correlation. Bulmer describes Galton's early ambitions and experiments—his investigations of problems of evolutionary importance (such as the evolution of gregariousness and the function of sex), and his movement from the development of a physiological theory to a purely statistical theory of heredity, based on the properties of the normal distribution. This work, culminating in the law of ancestral heredity, also put Galton at the heart of the bitter conflict between the "ancestrians" and the "Mendelians" after the rediscovery of Mendelism in 1900. A graceful writer and an expert biometrician, Bulmer details the eventual triumph of biometrical methods in the history of quantitative genetics based on Mendelian principles, which underpins our understanding of evolution today.
The Animal Answer Guide
Frogs are amazingly diverse—ranging from the massive goliath frog, which weighs several pounds, to the recently discovered gold frog, which measures a mere three-eighths of an inch when fully grown—and have inhabited the earth for more than 200 million years. Today, however, these amphibians face more challenges than any other vertebrate group. In this fun and informative book, herpetologists Mike Dorcas and Whit Gibbons answer common and not-so-common questions people may have about these fascinating animals. Dorcas and Gibbons discuss how frogs evolved, which species currently exist in the world, and why some have recently gone extinct. They reveal what frogs eat and what eats them, their role in cultures across the globe, why many populations are declining and what we can do to reverse this dangerous trend, why there are deformed frogs, and much more. They answer expected questions such as “What is the difference between a frog and a toad?” and “Why do some people lick toads?” and unexpected ones such as “Why do some frogs lay their eggs in the leaves of trees?” and “Do frogs feel pain?” The authors’ easy-to-understand yet thorough explanations provide insight into the amazing biology of this amphibian group. In addressing conservation questions, Dorcas and Gibbons highlight the frightening implications of the current worldwide amphibian crisis, which many scientists predict will bring extinction rates experienced by frog species to levels not seen in any vertebrate animal group in millions of years. Packed with facts and featuring two color galleries and 70 black-and-white photographs, Frogs: The Animal Answer Guide is sure to address the questions on the minds of curious naturalists.
With many frog populations declining or disappearing and developmental malformations and disease afflicting others, scientists, conservationists, and concerned citizens need up-to-date, accurate information. Frogs of the United States and Canada is a comprehensive resource for those trying to protect amphibians as well as for researchers and wildlife managers who study biodiversity.
