Book Description
The spider genus Selenops occurs in both the Old World and New World subtropics and tropics and contains nearly half of the species in the family Selenopidae. These spiders are extremely flattened dorsoventrally and are amongst the fast-est animals in the world. Despite the large size of some species, these aforementioned characteristics can make them difficult to detect. In this monograph the species from North America, Central America and Caribbean Islands (excluding Cuban endemics) are revised. In total, 21 new species are described and 6 species are synonymized. The males of S. bani and S. marcanoi, and the females of S. phaselus and S. geraldinae are described for the first time. Almost all species are redescribed, with new illustrations, including the internal female copulatory organs, most of which are illustrated for the first time. New distributional records and a key to species are also provided.

Book Description
ÿThe Selenopidae are a family of medium to large spiders with extremely flattened bodies. They are exceptional in that both their running and striking speeds place them amongst the world?s fastest animals. They occur in all habitable continents but are most abundant in tropical and adjacent realms. Selenopid spiders are usually found under rocks or under tree bark, and have the ability to squeeze into tight crevices. The family currently comprises around 200 species in five genera. In this monograph, four new genera and 27 new species are described from Australia and the Oriental Region, bringing the world total to nine genera and over 230 species. Several species previously placed in Selenops are transferred to the new genera. The Australian fauna is found to be more diverse than previously documented with a total of 24 species, 23 of which are new. A key to the genera of Selenopidae is provided, as are keys to the species of the new genera Karaops and Makdiops.

Book Description
Biological diversity, or "biodiversity," refers to the variety of all life on earth, and the complex relationships among living things, and between living things and their environment. Biodiversity includes genetic variety, species diversity, and variability in communities, ecosystems and landscapes. Biodiversity sustains the environments in which we live and on which our lives and those of every other living creature on Earth depend. Thanks to biodiversity, we are able to obtain such necessary goods as food, clothing, medicine, and fuel. Equally important are the ecosystem services that biodiversity provides, such as clean air and drinkable water. Conservation scientists have identified a number of universal threats to biodiversity: habitat loss and degradation, invasive species, pollution, overpopulation, overexploitation and consumption, and global climate change. This book examines critical issues in this field from researchers around the globe.

Book Description
With over 40,000 described species, spiders have adapted to nearly every terrestrial environment across the globe. Over half of the world’s spider families live within the three contiguous Pacific Coast states—not surprising considering the wide variety of habitats, from mountain meadows and desert dunes to redwood forests and massive urban centers. This beautifully illustrated, accessible guide covers all of the families and many of the genera found along the Pacific Coast, including introduced species and common garden spiders. The author provides readers with tools for identifying many of the region’s spiders to family, and when possible, genus and species. He discusses taxonomy, distribution, and natural history as well as what is known of the habits of the spiders, the characters of families, and references to taxonomic revisions of the pertinent genera. Full-color plates for each family bring to life the incredible diversity of this ancient arachnid order.
