This book was released on 2014 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: The new genus Aposphragisma (Araneae, Oonopidae, Oonopinae) comprising the new species A. baltenspergerae, A. borgulai, A. brunomanseri, A. confluens, A. dayak, A. dentatum, A. draconigenum, A. hausammannae, A. helvetiorum, A. kolleri, A. menzi, A. monoceros, A. nocturnum, A. retifer, A. rimba, A. salewskii, A. scimitar, A. sepilok and A. stannum is described. It is characterised by very hard bodied, strongly sclerotized species with completely armoured prosoma and strongly sclerotized ventral and dorsal abdominal scuta. Aposphragisma gen. nov. is placed within the Gamasomorphagroup sensu Saaristo (2001). Descriptions and illustrations are given for all new species. A phylogenetic analysis based on 40 characters using Prethopalpus fosuma, Gamasomorpha asterobothros, G. cataphracta, G. seximpressa, Xestaspis biflocci, X. kandy and X. paulina as outgroup-taxa and Cortestina thaleri (Oonopidae, Sulsulinae) as the root is presented and discussed. Furthermore it is shown that females of Aposphragisma gen. nov. possess complex internal genitalia. The members of the new genus are ground-dwelling litter inhabitants restricted to Southeast Asian lowland and montane forests, with more than 60% of the species only known from single localities. They are presumed to be negatively affected by the massive destruction of pristine forest habitats within their range. This work has been conducted within the framework of the Planetary Biodiversity Inventory (PBI) of Oonopidae (see http://research.amnh.org/oonopidae).

Available in PDF, EPUB and Kindle. Book excerpt: Transportation of species to areas outside their native ranges has been a feature of human culture for millennia. During this time such activities have largely been viewed as beneficial or inconsequential. However, it has become increasingly clear that human-caused introductions of alien biota are an ecological disruption whose consequences rival those of better-known insults like chemical pollution, habitat loss, and climate change. Indeed, the irreversible nature of most alien-species int- ductions makes them less prone to correction than many other ecological problems. Current reshuffling of species ranges is so great that the present era has been referred to by some as the “Homogocene” in an effort to reflect the unique mag- tude of the changes being made. These alien interlopers often cause considerable ecological and economic d- age where introduced. Species extinctions, food-web disruptions, community alte- tions, ecosystem conversion, changes in nutrient cycling, fisheries collapse, watershed degradation, agricultural loss, building damage, and disease epidemics are among the destructive – and frequently unpredictable – ecological and economic effects that invasive alien species can inflict. The magnitude of these damages c- tinues to grow, with virtually all environments heavily used by humans now do- nated by alien species and many “natural” areas becoming increasingly prone to alien invasion as well. Attention to this problem has increased in the past decade or so, and efforts to prevent or limit further harm are gaining wider scientific and political acceptance.

Available in PDF, EPUB and Kindle. Book excerpt: Forest Spiders of South East Asia offers the first comprehensive systematic account of all sac and ground spiders of South East Asia, which together constitute an estimated 12% of all spiders in the region. All ten subfamilies, 57 genera and numerous species of the region are defined, described, and illustrated. One new subfamily and a large number of new genera and species are described and named. Several hundreds additional, described and new, species are referred to. Distribution of all species covered in this volume is shown in 50 maps. More than a thousand line drawings and 16 colour photographs are used to illustrate the descriptions of the species, of which the great majority has never been illustrated before. The book provides a modern revision of all sac and ground spiders with clear illustrated diagnosis and descriptions of all known members of this group and many new species and genera. Identification of all 47 families occurring in the region is illustrated in beautiful and detailed drawings.

This book was released on 2012 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although originally described from St. Vincent in the Lesser Antilles, the goblin spider genus Ischnothyreus Simon appears to be an Old World taxon that is represented in the New World only by two presumably introduced, pantropical, synanthropic species: I. peltifer (Simon) and I. velox Jackson. Two specific names based on New World specimens (I. barrowsi Chamberlin and Ivie from Florida, and I. indressus Chickering from the Lesser Antilles) are placed as junior synonyms of I. velox, which is newly recorded from Mexico, Panama, Jamaica, Hispaniola, Venezuela, Brazil, Madagascar, the Philippines, the Marshall Islands, Hawaii, the Marquesas Islands, and New Caledonia. A third species, I. browni Chickering, that is supposedly from Costa Rica was apparently based on mislabeled specimens that are actually from the Philippines. The type specimens of I. browni resemble those of the Seychelle species Ischnothyrella jivani (Benoit) in that the dorsal abdominal scutum of males is extremely weak and that of females is either greatly reduced or entirely lost. Both species nevertheless share the synapomorphies of Ischnothyreus, and the generic name Ischnothyrella Saaristo is therefore placed as a junior synonym of Ischnothyreus.

This book was released on 2015 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three new genera of soft-bodied, oonopine goblin spiders are established. Two specific names (Oonops tolucanus Gertsch and Davis, Oonops chickeringi Brignoli) are transferred to the new genus Toloonops, characterized by retaining a separate palpal bulb and cymbium, having the cymbial cone near the cymbial margin, and having posteriorly directed projections on the male endites that originate far from the anterior endite margins; five new species are described: T. chiapa, T. jacala, T. veracruz, T. belmo, and T. verapaz. Six similar new species, united by having a stepped male endite profile and a subapical sclerite on the anterior genitalic process of females, are assigned to the new genus Guatemoonops: G. purulha, G. rhino, G. jaba, G. chilasco, G. augustin, and G. zacapa. Oonops mckenziei Gertsch is transferred to the new genus Emboonops, characterized by having a fused palpal bulb and cymbium, a hypertrophied embolus, and often a V-shaped female anterior genitalic process; nine new species are described: E. tuxtlas, E. tamaz, E. catrin, E. nejapa, E. calco, E. palenque, E. bonampak, E. arriaga, and E. hermosa.

This book was released on 2011 with total page 51 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dysderina Simon is one of the largest of the classical genera of goblin spiders, containing numerous species that have been associated only because they are heavily scutate gamasomorphines with long, paired spines on the ventral surface of the anterior tibiae and metatarsi. The Old World species that have been assigned to the genus are wildly misplaced, and the New World fauna constitutes a complex of over 225 species belonging to at least nine genera. The northern Andes house a highly diverse fauna, both of Dysderina itself and of closely related genera. The new genus Scaphidysderina is established for one of those related but distinct Andean groups, characterized by a crenulated sternum and by the reduction or loss of the dorsal abdominal scutum in females. Seventeen new species are described from Peru (S. manu, S. pagoreni, S. scutata, S. cajamarca), Ecuador (S. tayos, S. loja, S. molleturo, S. tapiai, S. pinocchio, S. palenque, S. tandapi, S. napo, S. baerti, S. cotopaxi, S. andersoni), and Colombia (S. hormigai, S. iguaque). Males of several species show remarkable modifications of the chilum and chelicerae; the chilum is sometimes enlarged to form a conspicuous snout, and the chelicerae often bear a heavily sclerotized, dorsally directed spine. A second new genus, Costarina, is established to contain the most commonly encountered species that have been misplaced in Dysderina; Dysderina plena O. P.-Cambridge, from Mexico, is chosen as the type species, and 15 additional taxa, all described from Central America by Chickering, are transferred from Dysderina to Costarina: D. abdita, D. belinda, D. concinna, D. dura, D. humphreyi, D. improvisa, D. intempina, D. meridina, D. obtina, D. potena, D. recondita, D. rigida, D. seclusa, D. silvatica, and D. watina.

Available in PDF, EPUB and Kindle. Book excerpt: The U.S. government defines invasive species as "an alien species whose introduction does or is likely to cause economic or environmental harm or harm to human health." Invasive Species in the Pacific Northwest describes these species, how they got here, and the effects of their invasions on the region's environment. Each of 108 invasive species of fish, plants, invertebrates, mammals, and birds -- including earthworms, domestic cats and pigs, blackberries, European fruit flies, Japanese eelgrass, Mediterranean mussels, rats, and terrestrial mollusks -- is described in a 2-page spread that includes a full-color photograph of the species, a map showing the species' presence in the region, plus: -- Impact on communities and native species -- Control methods and management -- Life histories and species overview -- History of invasiveness Included are suggestions to help reduce the spread of invasive species; habitat preferences of Pacific Northwest invasive species; the World Conservation Union (ICUN) list of the world's 100 most invasive alien species; and a questionnaire designed to evaluate ecological impact and invasive potential. Invasive species have been recognized as an environmental issue since Charles Darwin's voyage on the H.M.S. Beagle. Editors P. D. Boersma, S. E. Reichard, and A. N. Van Buren explore the intentional and accidental introductions of invasive species. Whether these species were deliberately brought to the Northwest for agricultural, horticultural, aquacultural, or hunting and fishing purposes, or accidentally introduced as stowaways and contaminants, knowledge about them is integral to the protection of our environment.

Book excerpt: Kin Recognition in Protists and Other Microbes is the first volume dedicated entirely to the genetics, evolution and behavior of cells capable of discriminating and recognizing taxa (other species), clones (other cell lines) and kin (as per gradual genetic proximity). It covers the advent of microbial models in the field of kin recognition; the polymorphisms of green-beard genes in social amebas, yeast and soil bacteria; the potential that unicells have to learn phenotypic cues for recognition; the role of clonality and kinship in pathogenicity (dysentery, malaria, sleeping sickness and Chagas); the social and spatial structure of microbes and their biogeography; and the relevance of unicells’ cooperation, sociality and cheating for our understanding of the origins of multicellularity. Offering over 200 figures and diagrams, this work will appeal to a broad audience, including researchers in academia, postdoctoral fellows, graduate students and research undergraduates. Science writers and college educators will also find it informative and practical for teaching.

Available in PDF, EPUB and Kindle. Book excerpt: Carrion, or dead animal matter, is an inherent component of aquatic and terrestrial ecosystems worldwide, and is exploited by a wide diversity of organisms from different trophic levels, including microbes, arthropods and vertebrates. Further, carrion consumption by scavengers, i.e. scavenging, supports key ecosystem functions and services such as recycling nutrients and energy, disposing of carcasses and regulating disease spread. Yet, unlike dead plant matter, dead animal decomposition has received little attention in the fields of ecology, wildlife conservation and environmental management, and as a result the management of carrion for maintaining biodiversity and functional ecosystems has been limited. This book addresses the main ecological patterns and processes relating to the generation and consumption of carrion both in terrestrial and aquatic ecosystems. It also discusses a number of conservation concerns and associated management issues, particularly regarding the increasing role of human-mediated carrion in ecosystems. Lastly, the book outlines future research lines in carrion ecology and management, and identifies the major challenges for scavengers and scavenging processes in the Anthropocene.
