Amphibians of North Africa is a comprehensive compilation of available data on the amphibians and reptiles found in various ecosystems across North West Africa and parts of the Mediterranean region. It is essential to identifying and understanding the ecological role of regional herpetofauna and its conservational importance. It examines the biological origins and diversity of amphibians in North Africa, along with their diverse ecosystems, including deserts, grasslands and subtropical forests. The book features detailed descriptions of the adult and larvae stages of species, such as the North African fire salamander, the common painted frog, Brongersma's toad and the Mediterranean tree frog. This book is a vital resource for herpetology and ecology students and researchers, helping them identify, understand and conserve these amphibians and reptiles in their various habitats across the North African and Mediterranean regions.
Chirality is a fundamental, persistent, but often overlooked feature of all living organisms on the molecular level as well as on the macroscopic scale. The high degree of preference for only one of two possible mirror image forms in Nature, often called biological homochirality is a puzzling, and not yet fully understood, phenomenon. This book covers biological homochirality from an interdisciplinary approach - contributions range from synthetic chemists, theoretical topologists and physicists, from palaeontologists and biologists to space scientists and representatives of the pharmaceutical and materials industries. Topics covered include - theory of biochirality, origins of biochirality, autocatalysis with amplification of chirality, macroscopic (present) biochirality, fossil records of chiral organisms - paleochirality, extraterrestrial origin of chirality, exceptions to the rule of biological homochirality, D-amino acids, chemical transfer of chirality, PV effects, and polarised radiation chemistry.
This comprehensive book contains the latest information on diverse biological functions of relaxin and related peptide found since the recent discovery of relaxin receptors. It also describes the evolution of relaxin family peptides and their receptors, molecular mechanisms of ligand/receptor interaction and the analysis of activated signaling pathways.

Encyclopedia of Deserts represents a milestone: it is the first comprehensive reference to the first comprehensive reference to deserts and semideserts of the world. Approximately seven hundred entries treat subjects ranging from desert survival to the way deserts are formed. Topics include biology (birds, mammals, reptiles, amphibians, fishes, invertebrates, plants, bacteria, physiology, evolution), geography, climatology, geology, hydrology, anthropology, and history. The thirty-seven contributors, including volume editor Michael A. Mares, have had extensive careers in deserts research, encompassing all of the world’s arid and semiarid regions. The Encyclopedia opens with a subject list by topic, an organizational guide that helps the reader grasp interrelationships and complexities in desert systems. Each entry concludes with cross-references to other entries in the volume, inviting the reader to embark on a personal expedition into fascinating, previously unknown terrain. In addition a list of important readings facilitates in-depth study of each topic. An exhaustive index permits quick access to places, topics, and taxonomic listings of all plants and animals discussed. More than one hundred photographs, drawings, and maps enhance our appreciation of the remarkable life, landforms, history, and challenges of the world’s arid land.
Part 1 of The Butterflies of Venezuela was a pioneering work of its kind for South America, being the first authoritative volume in a comprehensive faunistic identification series. The series will prove invaluable to all who wish to learn about the remarkable and diverse butterfly fauna of this country and continent. Approximately 1000 species of adult Nympbalidae, Papilionidae, and Pieridae will be treated in the four-part series, equivalent to over one-third of the total Neotropical species in these families. Drawing on over 20 years of personal research in the field, in collections, and in libraries, the detailed accounts for each species encapsulate all that is known about their identification, distribution, behaviour, habitat, and foodplants. The text, which has been written to appeal to specialists and amateurs alike, has been collated from a wealth of published and unpublished sources. It includes extensive commentary on the systematics and nomenclature employed, and provides detailed notes designed to permit the easy identification of every Venezuelan butterfly. General notes on early stages are provided in the introduction to each genus, and where available those of one representative species are fully described. Readers also benefit from the inclusion of an extensive bibliography, which in Part 2 alone comprises almost 800 works fully referenced in the text. Unlike many other guides, the photographic colour plates illustrate every subspecies, generally showing both sexes and wing surfaces for each, plus several representative specimens for highly variable taxa. In addition, a large number of type specimens are reproduced, many of them for the first time. Part 1 cover 276 species including 2 new species and 23 new subspecies. Part 2 treats 196 species incl. 355 subspecies and the colour plates figures over 450 type specimens. 8 new species and 95 new spubspecies are described. 4 neotypes and 10 lectopypes are designated. Part 3 is projected to treat the Papilionidae, Brassolinae, Danainae, and first part of Satyrinae (Pronophilina and Erebiina). Part 4 will cover the family Pieridae and the remaining Satyrinae and Heliconiinae.
In a Panamanian pond, male túngara frogs (Physalaemus pustulosus) gather in choruses, giving their "advertisement" call to the females that move among them. If a female chooses to make physical contact with a male, he will clasp her and eventually fertilize her eggs. But in vying for the females, the males whose calls are most attractive may also attract the interest of another creature: the fringe-lipped bat, a frog eater. In the Túngara Frog, the most detailed and informative single study available of frogs and their reproductive behavior, Michael J. Ryan demonstrates the interplay of sexual and natural selection. Using techniques from ethology, behavioral ecology, sensory physiology, physiological ecology, and theoretical population genetics in his research, Ryan shows that large males with low-frequency calls mate most successfully. He examines in detail a number of explanations for the females' preferences, and he considers possible evolutionary forces leading to the males' success. Though certain vocalizations allow males to obtain mates and thus should be favored by sexual selection, this study highlights two important costs of such sexual displays: the frogs expand considerable energy in their mating calls, and they advertise their whereabouts to predators. Ryan considers in detail how predators, especially the frige-lipped bat (Trachops cirrhosus), affect the evolution of the túngara frog's calls.
In 1993 and 1994, two Rapid Assessment Program teams conducted biological surveys in the Cordillera del Cóndor between Ecuador and Peru, one of the largest intact regions of Andean lower montane forest. This book presents the results of their surveys. The great topographic and geological complexity of this region, combined with a climate of year-round high humidity, have resulted in very high plant species diversity. This diversity of habitats and species with restricted distributions makes the Cóndor an important refuge for many taxa.
