Book excerpt: Snakes of the World: A Catalogue of Living and Extinct Species—the first catalogue of its kind—covers all living and fossil snakes described between 1758 and 2012, comprising 3,509 living and 274 extinct species allocated to 539 living and 112 extinct genera. Also included are 54 genera and 302 species that are dubious or invalid, resulting in recognition of 705 genera and 4,085 species. Features: Alphabetical listings by genus and species Individual accounts for each genus and species Detailed data on type specimens and type localities All subspecies, synonyms, and proposed snake names Distribution of species by country, province, and elevation Distribution of fossils by country and geological periods Major taxonomic references for each genus and species Appendix with major references for each country Complete bibliography of all references cited in text and appendix Index of 12,500 primary snake names The data on type specimens includes museum and catalog number, length and sex, and collector and date. The listed type localities include restrictions and corrections. The bibliography provides complete citations of all references cited in the text and appendix, and taxonomic comments are given in the remarks sections. This standard reference supplies a scientific, academic, and professional treatment of snakes—appealing to conservationists and herpetologists as well as zoologists, naturalists, hobbyists, researchers, and teachers.

Available in PDF, EPUB and Kindle. Book excerpt: remnants of gene pools of these species. Badghyz Natural Reserve, established in 1941, became a refuge for the last existing population of the Turkmen onager (Equus hemionus onager) and a unique pistachio woodland. A new generation oflocal Turkmen scientists, many of whom were trained by the Russian researchers in the graduate schools of Moscow and Leningrad arose from the 1930s through the 1950s. The Turkmen Academy of Sciences and its journal, Proceedings (including the monthly biological series), served to record the results of diverse biological studies in the republic. While basic science in the Middle Asian republics rather gained from the Russian "colonial" influence, natural resources, in contrast, were severely damaged by the Soviet way of handling the economy and social issues. Severe environmental problems have been inherited by the now independent Turkmenistan, including overgrazed desert pastures, deforested mountains, depleted water resources, accumulated pesticides in cotton fields, declining populations of endangered species of animals and plants, and - worst of al- progressing, human-caused desertification (Kharin this volume). In order to approach a solution to these problems, scientists and officials in the republic will need the close attention and help of the international scientific community.

Book excerpt: Книга представляет собой первый обзор на английском языке систематики и биологии компактного таксона ящериц (около 20 видов), обитающих в пересеченных аридных и высокогорных ландшафтах Евразии и северо-восточной Африки. Эти рептилии в последнее время привлекают пристальное внимание герпетологов из-за своей заметности, обязанной сугубо дневному образу жизни и высокой численности и плотности популяций, характерной для большинства видов. До сих пор интерес герпетологов был сосредоточен главным образом на систематике и номенклатуре горных агам, а серьезные исследования по их образу жизни, экологии и поведению крайне немногочисленны. В этой книге наряду с обзором наиболее важной опубликованной информацией по изученным представителям таксона дана развернутая картина всех сторон биологии модельного вида – кавказской агамы Paralaudakia caucasia и его взаимоотношений с другим – хорасанской агамой P. erythrogaser. На протяжении 10 лет полевых исследований прослеживались биографии многих конкретных особей и изучались тонкие детали коммуникативного процесса в нескольких локальных популяциях. В основу исследования положен анализ социального поведения как фактора, интегрирующего дем в некую общность системной природы. Главной задачей было рассмотреть структуру в ее трансформациях из года в год как процесс изменений в поведении и социальных ролях взрослых особей и детенышей, ежегодно пополняющих контингент дема.Другие важные темы, затронутые в книге – это разнообразие носителей коммуникативной информации (оптическая, химическая, тактильная) у модельного и ряда других видов, а также характер взаимоотношений между близкородственными формами в зонах их контакта.
