Book excerpt: In The Greenland Entomofauna an international team of 64 taxonomic specialists provide for the first time a richly illustrated guide to the identification of the ≈1200 species of Hexapods/Insects, Arachnids and Myriapods so far known to occur in the country. While the composition, origin and adaptations of the Greenland fauna has always been a challenge to biogeographers and ecologists/ecophysiologists, the provision of a tool for detailed identification of its constituent species is now particularly timely, since global climate change will expectedly have a particularly noticeable impact on biota at high latitudes. This obviously renders the feasibility of monitoring distributional range shifts of the principal components of this biota a matter of some urgency.

Book excerpt: "Abstract: This paper presents a catalogue of oribatid mites (Acari, Oribatida) recorded from Continental Southeast Asia (CSEA) covering a period of 55 years from 1965 to the first half of 2020. This subregion comprises countries that are located on the southeastern coast of the Asian continent, namely, Myanmar, Thailand, Laos, Cambodia and Vietnam. For each species, information is compiled on references to the original description, subsequent re-combinations of specific name with other genera, and junior synonyms used in CSEA literature, if any, as well as type habitat, habitats recorded later, and distribution within outside CSEA. A historical review of explorations and taxonomic studies in the various countries is also provided. A total of 820 valid species including subspecies and seven doubtful species are known so far from CSEA. The valid species belong to 313 genera and subgenera, 94 families and 36 superfamilies in all of the five infraorders and two hyporders of the Suborder Oribatida. The Hyporder Brachypylina is most diverse with 620 species, followed by Mixonomata (88), Enarthronota (65), Nothrina (41), Palaeosomata (5) and Parhyposomata (1). Vietnam whose fauna has been best explored tops the records with 730 species, followed by a low second by Thailand (137), then Cambodia (37) and Myanmar (11) while the oribatid fauna of Laos is still entirely unknown. Altogether, the oribatid fauna of Southeast Asia (SEA), including its two subregions, now totals 1601 species belonging to 477 genera, 109 families and 40 superfamilies. Species that are known so far only from CSEA countries and thus probably endemic is highest at 36.4% for Myanmar, 32,1% for Thailand, 23.7% for Vietnam, 0 for Cambodia, 27.2% for CSEA, 59.0% for the Malay Archipelago, and 48.7% for SEA as a whole. About 7% of the recorded species of Thailand and Vietnam are cosmopolitan or semicosmopolitan in distribution, but their faunal elements are decidedly Oriental, with about half (43-54%) occurring also in other Oriental countries. The same countries also share in common many species with other zoogeographic regions, viz. 12-14% Palaearctic, 8-16% Australian, 8-11% Neotropical, 3-11% Ethiopian, and 1-3% Nearctic..

This book was released on 2013-10-08 with total page 505 pages. Available in PDF, EPUB and Kindle. Book excerpt: More than 40,000 species of mites have been described, and up to 1 million may exist on earth. These tiny arachnids play many ecological roles including acting as vectors of disease, vital players in soil formation, and important agents of biological control. But despite the grand diversity of mites, even trained biologists are often unaware of their significance. Mites: Ecology, Evolution and Behaviour (2nd edition) aims to fill the gaps in our understanding of these intriguing creatures. It surveys life cycles, feeding behaviour, reproductive biology and host-associations of mites without requiring prior knowledge of their morphology or taxonomy. Topics covered include evolution of mites and other arachnids, mites in soil and water, mites on plants and animals, sperm transfer and reproduction, mites and human disease, and mites as models for ecological and evolutionary theories.

Available in PDF, EPUB and Kindle. Book excerpt: Mites and ticks are everywhere and acarologists go after them – some explore their bewildering diversity, others try to understand their how and why. For the past 50 years, the International Congress of Acarology has been the forum for worldwide communication on the knowledge of Acari, helping researchers and students to look beyond their disciplines. Many mites and ticks are economic factors as they are pests of agricultural, veterinary and medical importance, and several species have become model organisms in modern biology. The 96 contributions to Trends in Acarology – reflecting fields as molecular biology, biochemistry, physiology, microbiology, pathology, ecology, evolutionary biology, systematic biology, soil biology, plant protection, pest control and epidemiology – have been reviewed and carefully edited. This volume contains a wealth of new information, that may stimulate research for many years to come.

Book excerpt: The world of mites, being exceptionally diverse and rich, may be analysed both in historical and geographical terms. It is commonly known that these tiny, ubiquitous invertebrates are found both in terrestrial and aquatic ecosystems; additionally, they are relatively abundant in aeroplankton. The species composition and character of their assemblages vary, and they are different in the polar, temperate and tropical regions. All the above-mentioned factors force scientists to apply a unique approach to research problems and specifically define the aims of their investigations. The Diversity Special Issue on "Biodiversity of Mites" contains complex acarological issues including zoogeographic, ecological and parasitological research conducted in several regions of the world. The results of the presented research concern various taxonomic groups of mites occurring in both terrestrial and aquatic environments. Therefore, they can be an inspiration to search for new research directions and solve contemporary scientific problems.

This book was released on 2015-04-30 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: The history of biological control of harmful organisms by mites is marked by outstanding achievements with a few premiere natural enemies. Early works concentrated on the use of predatory mites for the control of synanthropic flies, More recently, the focus has been mostly on mites of the family Phytoseiidae for the control of plant feeding mites. This is an important family of acarine predators of plant pest mites, which are effectively used in agriculture worldwide. Besides the vast knowledge in several species in this family, there are as well many opportunities for biological control, represented in an array of organisms and through the improvement of management techniques, which are constantly explored by researchers worldwide. This has resulted in an increasing interest in predatory mite species within the families Stigmaeidae, Ascidae, Laelapidae, Rhodacaroidea, Macrochelidae, Erythraeidae and Cheyletidae, among others. This book will compile important developments with predatory mite species within these families, which are emerging as important tools for integrated pest management. New developments with predatory insects and pathogenic organisms attacking mites will also be a subject of this book. Finally, the potential and gaps in knowledge in biological control of acarine plant pests will be addressed.

Available in PDF, EPUB and Kindle. Book excerpt: Igapó forests are a common part of the Amazon whose ecosystems are critical to our shared human future. The introduction addresses the structure, function and dynamics of igapó forests in the Amazon basin, focusing on their uniqueness due to their high level of complexity defined as the many ways that different components of igapó forests in the Amazon basin ecosystem interact and also on how those interactions are on a higher-order compared to other tropical forests. The text then breaks down the igapó ecosystem using these sections: (1) Igapó forests over space and time, (2) Water, light and soils, (3) The carbon cycle, (4) Litter, fungi and invertebrates, (5) Vertebrates, (6) Plant population studies, (7) Plant community studies, and (8) Human impacts and management. Experts from around the world serve as chapter authors that review what is known about their specific part of the igapó ecosystem, what research they have done, and also what needs to be done in the future.

This book was released on 2010-01-06 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forensic Entomology deals with the use of insects and other arthropods in medico legal investigations. We are sure that many people know this or a similar definition, maybe even already read a scientific or popular book dealing with this topic. So, do we really need another book on Forensic Entomology? The answer is 13, 29, 31, 38, and 61. These are not some golden bingo numbers, but an excerpt of the increasing amount of annual publications in the current decade dealing with Forensic Entomology. Comparing them with 89 articles which were published d- ing the 1990s it illustrates the growing interest in this very special intersection of Forensic Science and Entomology and clearly underlines the statement: Yes, we need this book because Forensic Entomology is on the move with so many new things happening every year. One of the most attractive features of Forensic Entomology is that it is multid- ciplinary. There is almost no branch in natural science which cannot find its field of activity here. The chapters included in this book highlight this variety of researches and would like to give the impetus for future work, improving the dev- opment of Forensic Entomology, which is clearly needed by the scientific com- nity. On its way to the courtrooms of the world this discipline needs a sound and serious scientific background to receive the acceptance it deserves.

This book was released on 2004-12-30 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: Paleolimnology is a rapidly developing science that is now being used to study a suite of environmental and ecological problems. This volume is the fourth handbook in the Developments in Paleoenvironmental Research book series. The first volume (Last & Smol, 2001a) examined the acquisition and archiving of sediment cores, chronological techniques, and large-scale basin analysis methods. Volume 2 (Last & Smol, 2001b) focused on physical and chemical methods. Volume 3 (Smol et al. , 2001), along with this book, summarize the many biological methods and techniques that are available to study long-term environmental changeusing information preserved in sedimentary profiles. A subsequent volume (Birks et al. , in preparation) will deal with statistical and data handling procedures. It is our intent that these books will provide sufficient detail and breadth to be useful handbooks for both seasoned practitioners as well as newcomers to the area of paleolimnology. These books will also hopefully be useful to non-paleolimnologists (e. g. , limnologists, archeologists, palynologists, geographers, geologists, etc. ) who continue to hear and read about pal- limnology, but have little chance to explore the vast and sometimes difficult to access journal-based reference material for this rapidly expanding field. Although the chapters in these volumes target mainly lacustrine settings, many of the techniques described can also be readily applied to fluvial, glacial, marine, estuarine, and peatland environments. This current volume focuses on zoological indicators preserved in lake sediments, whilst Volume 3 focused on terrestrial, algal, and siliceous indicators.

Book excerpt: Although the ancestral home of chelicerates was the sea, the vast majority of modern species live on land. Most students of spiders and mites also restrict themselves to terrestrial habitats. However, a surprising number of mites (Arachnida: Acari) have returned to a watery existence. Approximately 7000 species from the Mesostigmata, Astigmata, Oribatida, and especially the Prostigmata, now live in marine and freshwater habitats. In Aquatic Mites, a dozen chapters explore the distribution, ecology, behavior, genetics, and evolution of the most diverse of these astonishing arachnids. The results of these studies raise as many interesting questions as they answer, and should provoke more investigations of the biology of freshwater and marine Acari.
