"La contribution des Arabes à la médecine, à l'astronomie, aux mathématiques, est universellement reconnue. En revanche, la zoologie est négligée jusque dans les traités d'histoire des sciences les plus complets. Selon cette même idée, les Arabes n'auraient servi que d'intermédiaire, n'ayant eu comme seul mérite d'avoir transmis l'inestimable héritage grec, qui a permis plus tard le développement de la science occidentale. Le latâb al-hayatvân d'Al-Jâhiz, Le Livre des animaux, ouvrage en huit volumes, montre que ce point de vue hâtif n'est plus défendable. Al-Jâhiz, le plus grand naturaliste arabe, a brossé une synthèse de tout le savoir zoologique connu de son temps.Il n'apparaît pas comme un simple compilateur des données de ses prédécesseurs, mais plutôt comme l'émetteur des critiques adressées à des autorités scientifiques considérées comme indiscutables à son époque, tel évidemment Aristote. Mieux encore, il ajoute au savoir de son temps ses propres observations et avance des opinions qui, dans bien des cas, concordent avec celles émises de nos jours. C'est ainsi qu'il a modifié, amélioré, transformé et créé, à partir des auteurs anciens mais aussi en s'aidant des ressources de sa propre civilisation, diverses branches de la zoologie ayant une identité propre, profondément originale par rapport à ses initiatrices grecques ou indiennes. Décrire la contribution méconnue d'Al-Jâhiz dans le domaine de la zoologie et, en particulier, dans celui de l'écologie et de l'éthologie, ouvre enfin sur la richesse des textes zoologiques du monde arabe médiéval."--Page 4 of cover.

Thanks to its size and geographic position, Texas is home to nearly 30,000 species of insects, likely making its insect population the most diverse in the nation. Ranging from eastern and western to temperate and tropical species, this vast array of insects can be difficult to identify. In Common Insects of Texas and Surrounding States, John and Kendra Abbott have created the state's most comprehensive field guide to help readers recognize and understand these fascinating creatures. Containing 1,300 species and more than 2,700 photographs, this guide offers a wealth of information about the characteristics and behaviors of Texas's insects. Each chapter introduces an order with a discussion of general natural history and a description of other qualities helpful in distinguishing its various species, while every species' entry provides a state map showing where it is most likely to be found, a key displaying its seasonal distribution, information about its habitat, and corresponding photos. Featuring colored tabs for quick reference, a glossary, and information about other arthropods, this guide is the perfect companion for anyone wanting to identify and learn more about the many insects of Texas.

On any warm summer day, you can easily observe damselflies around a vegetated pond or the rocks along the banks of a stream. Like the more familiar dragonfly, damselflies are among the most remarkably distinctive insects in their appearance and biology, and they have become one of the most popular creatures sought by avocational naturalists. Damselflies of Texas is the first field guide dedicated specifically to the species found in Texas. It covers 77 of the 138 species of damselflies known in North America, making it a very useful guide for the entire United States. Each species account includes: * illustrations of as many forms (male, female, juvenile, mature, and colour morphs) as possible * common and scientific names, with pronunciation * distribution map * key features * identifying characteristics * discussion of similar species * status in Texas * habitat, seasonality, and general comments In addition to photographing damselflies in the wild, the author and illustrator have developed a new process for illustrating each species by scanning preserved specimens and digitally painting them. The resulting illustrations show detail that is not visible in photographs. The book also contains chapters on damselfly anatomy, life history, conservation, names, and photography, as well as a list of species that may eventually be discovered in Texas, state and global conservation rankings, seasonality of all species in chronological order, and additional resources and publications on the identification of damselflies.

This is the first guide to dragonflies and damselflies of the south-central United States. The book covers 263 species, representing more than half of the North American fauna. The area of coverage significantly overlaps with other regions of the country making this book a useful aid in identifying the dragonflies and damselflies in any part of the United States, Canada or northeastern Mexico. More photographs of damselflies in North America appear here than in any other previously published work. All 85 damselfly and 178 dragonfly species found in the region are distinguished by photographs, numerous line drawings, keys, and detailed descriptions to help with identifications. Features include: *discussions of habitats, zoogeography, and seasonality. *details on dragonfly and damselfly life history and conservation *an introduction on studying and photographing dragonflies and damselflies *an entire section devoted to the external anatomy of dragonflies and damselflies *species accounts organized by family into sections on size, regional and general distribution, flight season, identification, similar species, habitat and biology and ecology *range maps for each species, as well as an extensive bibliography and a list of resources for further study.
