Download or read book Whip Spiders written by Peter Weygoldt and published by BRILL. This book was released on 2021-10-25 with total page 163 pages. Available in PDF, EPUB and Kindle. Book excerpt: Whip spiders (Amblypygi) can be large and terrifying animals with strong, raptorial pedipalps and long antenniform first legs that can produce a span of as much as 60 cm. Others are small and scarcely span 5 cm. They all lead a secretive nocturnal life and are extremely dangerous to other arthropods and small vertebrates. In contrast to spiders and scorpions, they are of no commercial, economic or medical importance and they are difficult to study in the field because of their nocturnal habits, possible reasons why they have been greatly neglected until recently, by scientists and naturalists. Whip spiders represent an old group that dates back to the Carboniferous period. Their partly primitive and partly derived morphological characters and habits make the study of these animals interesting, while observation of their behaviour greatly increases our knowledge and understanding of arachnids in general. In this book the author describes their morphology and systematics, their life history, their fascinating sensory biology, their complex mating dances and reproductive biology, and their ecology and distribution. Thus he has made a significant contibution to a better understanding of the morphology and biology of the Arachnida as a whole. Whip Spiders is an outstanding contribution to science and it will be of interest for anyone with an interest in Arachnida and for those keeping and breeding spiders.

This book was released on 2018 with total page 81 pages. Available in PDF, EPUB and Kindle. Book excerpt: Four genera formed a monophyletic group, referred to as the Kochius clade, in the phylogeny of the North American vaejovid scorpion subfamily Syntropinae Kraepelin, 1905: Balsateres González-Santillán and Prendini, 2013; Kochius Soleglad and Fet, 2008; Kuarapu Francke and Ponce-Saavedra, 2010; and Thorellius Soleglad and Fet, 2008. In the present contribution, all except Kochius, treated elsewhere, are revised. The monotypic Balsateres and Kuarapu are redescribed. Thorellius cristimanus (Pocock, 1898) and Thorellius intrepidus (Thorell, 1876) are redescribed and their type localities discussed and clarified. Three new species of Thorellius are described: Thorellius tekuani; Thorellius wixarika; and Thorellius yuyuawi. Vaejovis intrepidus atrox Hoffmann, 1931, is newly synonymized with T. cristimanus based on examination of the type material. A key to identification of the species of Thorellius is presented, and new locality records and updated distribution maps provided for all species covered.

This book was released on 2015 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Mexican vaejovid scorpion genus Konentontli González-Santillán and Prendini, 2013, was created to accommodate five species united, among other characters, by a subaculear tubercle on the telson. Species of Konetontli are among the smallest vaejovid scorpions. Their very small size, cryptic coloration, and apparently seasonal surface activity may explain their rarity in collections and it is likely that more undescribed species await discovery. In the present contribution, we describe four new species (Konetontli ignes, sp. nov.; Konetontli ilitchi, sp. nov.; Konetontli juxtlahuaca, sp. nov.; Konetontli migrus, sp. nov.) and revalidate Konetontli zihuatanejensis (Baldazo-Monsivaiz, 2003), comb. nov., previously synonymized with Konetontli acapulco (Armas and Martín-Frías, 2001), raising to 10 the number of species in the genus; redescribe previously described species, including the first description of the female of Konetontli nayarit (Armas and Martín-Frías, 2001); and present new records, comprehensive distribution maps, and a key to the identification of the species.

Available in PDF, EPUB and Kindle. Book excerpt: This diverse collection of research articles is united by the enormous power of modern molecular genetics. Every author accomplished two objectives: (1) making the field and the research described accessible to a large audience and (2) explaining fully the genetic tools and approaches that were used in the research. One fact stands out - the importance of a genetic approach to addressing a problem. I encourage you to read several chapters. You will feel the excitement of the scientists, and you will learn about an area of research with which you may not be familiar. Perhaps most importantly, you will understand the genetic approaches; and you will appreciate their importance to the research.
Download or read book Stress Signaling in Plants Genomics and Proteomics Perspective Volume 1 written by Maryam Sarwat and published by Springer Science & Business Media. This book was released on 2013-06-21 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant diseases, extreme weather caused by climate change, drought and an increase in metals in soil are amongst the major limiting factors of crop production worldwide. They devastate not only food supply but also the economy of a nation. Keeping in view of the global food scarcity, there is, an urgent need to develop crop plants with increased stress tolerance so as to meet the global food demands and to preserve the quality of our planet. In order to do this, it is necessary to understand how plants react and adapt to stress from the genomic and proteomic perspective. Plants adapt to stress conditions by activation of cascades of molecular mechanisms, which result in alterations in gene expression and synthesis of protective proteins/compounds. From the perception of the stimulus to transduction of the signal, followed by an appropriate response, the plants employ a complex network of primary and secondary messenger molecules. Cell signaling is the component of a complex system of communication that directs basic cellular activities and synchronizes cell actions. Cells exercise a large number of noticeably distinct signaling pathways to regulate their activity. In order to contend with different environmental adversities plants have developed a series of mechanisms at the physiological, cellular and molecular level. This two volume set takes an in-depth look at the Stress Signaling in Plants from a uniquely genomic and proteomics perspective. Stress Signaling in Plants offers a comprehensive treatise on the Chapter, covering all of the signaling pathways and mechanisms that have been researched so far. Each chapter provides in-depth explanation of what we currently know of a particular aspect of stress signaling and where we are headed. All authors have currently agreed and abstracts have been complied for the first volume, due out midway through 2012. We aim to have the second volume out at the beginning of 2013.
Download or read book Astrovirus Research written by Stacey Schultz-Cherry and published by Springer Science & Business Media. This book was released on 2012-10-12 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: Astroviruses were first identified in the feces of children in 1975. Since then, they have been found in ~ 3 to 20% of children with diarrhea. Given that serological studies have demonstrated that up to 90% of children have been exposed to at least one strain of astrovirus by age 9, the prevalence of infection may be much higher. Supporting this are studies demonstrating that astroviruses can also be isolated in a subset of asymptomatic individuals, suggesting that a proportion of infected individuals shed the virus asymptomatically or for some time after the resolution of other symptoms of infection. Asymptomatic carriers may be a major reservoir for astroviruses in the environment and could contribute to dissemination of the virus. Astroviruses are extremely stable in the environment and can be transmitted nosocomially, directly from infected individuals and potentially animals, and through contaminated food and water. Although typically an acute disease, astrovirus infection in premature infants may be associated with the development of necrotizing enterocolitis and in new-onset celiac disease in children. Immunocompromised children are even more susceptible often developing persistent infections that lead to wasting or even systemic infections associated with fatal encephalitis. In spite of its importance, little is known about astrovirus pathogenesis, molecular biology, epidemiology, or cell biology. The goal of this book is to provide the latest and most up-to-date information on this medically important and rapidly evolving group of viruses. It will include sections on the history of astroviruses and their disease in humans; information on viral replication and immune responses; new information on how astroviruses induce disease including the expression of a viral enterotoxin regulating intestinal epithelial cell tight junctions, the isolation and identification of new astrovirus genotypes in mammals including humans, and astroviruses of veterinary importance. Finally, the book will also introduce the complexity of astrovirus epidemiology and potential as an important new zoonotic disease, and its role in food-borne disease. This will be the first book of its kind and will be of great interest to microbiologists, virologists, infectious disease specialists, immunologists, pediatricians, public health and food safety experts, veterinarians, poultry industry specialists, and researchers and clinicians interested in enteritis.
