Download or read book A Taxonomic Revision of the Dirt Ants Basiceros Schulz 1906 Hymenoptera Formicidae written by Rodolfo Da Silva Probst and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Abstract: The ant genus Basiceros is an exclusively Neotropical group known for its cryptic habits. Based on a recent molecular phylogenetic framework, a comprehensive revisionary study of the genus is presented. Nine species are recognized, two of which are described as new (Basiceros browni sp. nov. and Basiceros tumucumaquensis sp. nov.). Basiceros redux (Donisthorpe 1939) is transferred to the genus Octostruma (O. reducta comb. nov.). As part of this revisionary work, taxonomic keys and images to all species and castes are provided. Castes and sexes (including larvae, males, and intercastes) are described for the first time for several Basiceros species. New records considerably expand the distributional range for most species. Natural history data and comments on character plasticity and convergence are also included. Keywords: Attini, systematics, morphology, mouthparts, ant larva, identification, Basiceros-genus group"--Page 3.

Download or read book Tropical Forests of the Guiana Shield written by D. S. Hammond and published by CABI. This book was released on 2005 with total page 552 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Guiana Shield is an ancient geological formation located in the northern part of South America, covering an area of one million square kilometres. Despite its hostile environment, it is home to many unusual and highly specialized plants and animals, which constitute a rich area of biodiversity. Chapters in this book include hydrology, nutrient cycling, forest phenology, insect-plant interactions, forest microclimate, plant distributions, forest dynamics and conservation and management of flora and fauna. It provides a comprehensive and detailed review of the ecology, biology and natural history of the forests of the area.
Download or read book Recent Advances in Lichenology written by Dalip Kumar Upreti and published by Springer. This book was released on 2015-02-09 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses in detail molecular, mycobiont culture, biomonitoring and bioprospection of lichens, providing insights into advances in different fields of lichenology by applying modern techniques and approaches and examining how their application has enhanced or changed classical approaches. It offers a valuable resource, especially for beginners, students and researchers from different academic backgrounds interested in the study of lichens. In recent years, the introduction of modern analytical techniques and approaches has significantly improved our understanding of the environment, including lichens. Lichens are unique organisms which possess untapped potential as effective and reliable bioindicators, sources of therapeutic phytochemicals, and as excellent extremophiles. The unique and peculiar characteristics of lichens underline the need for a multidimensional approach to explore their potential in various fields of environment science, botany and chemistry. Modern techniques, especially molecular techniques, have greatly enriched the field of lichen taxonomy and its position in the plant kingdom, revealing little-known species and exploring their evolutionary history, while multivariate analysis and GIS approaches have established lichens as an ideal and reliable tool for monitoring air pollution. Advanced culture techniques have expanded the pharmacological applications of lichens, which was formerly restricted due to their small biomass. The advent of sophisticated analytical instrumentation has now facilitated the isolation and characterization of lichens’ bioactive constituents, even in lower concentrations, as well as the estimation of their stress responses at different levels of pollution. As lichen diversity is adversely affected by increasing air pollution, there is a pressing need to develop effective management practices to conserve, restore and document lichen diversity.

Download or read book Insects of Panama and Mesoamerica written by Diomedes Quintero and published by . This book was released on 1992 with total page 732 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the highest concentrations of insect species in the world is found in Mesoamerica and the Isthmus of Panama. Yet visitors and others interested in this abudant region have until now been frustrated by the lack of literature useful for identifying and learning about this incredible array of insect life. This volume provides a wealth of information on many of the most common groups of these neotropical insects. Written for students and interested general readers as well as entomologists, the book aims to inspire increased interest in the study and conservation of this rich yet fragile biological region. The authors note that the volume was prepared with a special sense of urgency since the destruction of tropical forests has accelerated to such alarming proportions that today the Pacific lowland forests of Panama have been virtually extirpated, along with many of their native insect species, and other regions are threatened. Thus the gathering and publishing of information about this fragile and priceless natural heritage is an urgent task. The 42 chapters cover 20 insect orders and review the geology and biogeography of the area. The contributors offer a wide variety of viewpoints, ranging from natural history, to detailed ecological studies, to taxonomic treatments. The book introduces the majority of the smaller insect orders as well as diverse groups within larger orders. It is illustrated with hundreds of line drawings, distribution maps, and black-and-white photographs. A set of abstracts in English and Spanish is provided at the end of the book. This is the first work to focus on the insect fauna of Mesoamerica and Panama since Biologia Centrali-Americana, an exclusively systematic work published nearly 100 years ago.
