Insects are great classroom study organisms. They are easy to collect and raise and have a fascinating array of life histories. Because they are small and have tremendous reproductive capacity ecological studies of dispersion, predation, parasitism and reproduction can be studied in compressed timeframes and small areas relative to similar studies of larger organisms. Insects are also important bioindicators of the health of ecosystems. In a small space and with very little cost colonies of insects can be raised in classrooms for use in behavioral and physiological studies. The purpose of this book is to explain how to build and use insect collecting and rearing devices and through explanations of the various techniques stimulate educators to explore the study of insects in their classrooms. Insects are often given little consideration with regard to humane handling practices. Please remember that insects are living creatures and, as such, are entitled to the same treatment as other living creatures. Teachers should remember that students look to them for clues to the proper way of behaving in new situations. When collecting and working in the "field" educators should teach students to respect the environment. Do not collect more organisms than needed, treat all of the organisms you collect with care, and try not to leave signs of your presence in an area by returning rocks, logs, etc. to their original locations. If you must kill animals you've collected, do so quickly and humanely.

'Darwin cleared: official' This 1982 Times (7 January) head line of a first leader, reporting the astonishing case brought in Arkansas against compulsory teaching of a biblical account of creation, hopefully set at rest doubts about Darwin in the minds of a public confused by media presentations of such unfamiliar concepts as punctuated equilibria, cladism and phenetics. Mud sticks, but Darwin's perturbed ghost may have found some consolation in the concurrent celebrations at Grange-over-Sands, a modest township in Cumbria, UK, of the centenary of the publication of his less controversial book The Formation of Vegetable Mould through the Action of Worms. In the form of a symposium on earthworm ecology, this attracted some 150 participants, predominantly adrenalin-charged research workers in the full heat of peer-group interaction. This book comprises a selection of the more ecologically oriented papers contributed to the symposium, brutally edited in the interests of brevity and thematic continuity. The book opens with an appraisal of Darwin's earthworm work in its historical and philosophical context and relates his views on 'vegetable mould' to current concepts of humus formation. Thereafter, quotations from Darwin made out of piety have been rigorously excluded. Subsequent sections each comprise a review chapter and two or three 'case studies' presenting new data on a related topic."

The words pronounced by Serge Kreiter during the meeting come to mind. They could record exactly the situation of Acarology in Europe and in the World: "I think that in many European countries there are very few full time acarologists. It is very rare to have new positions available . . . . And public money, from the European Community but also from national countries, is very hard to get when you want to work on mites . . . . Could two acarological associations in Europe (Eur. A. Ac. and S. I. A. L. F) work together or, better, get married?" So, the fourth symposium of the European Acarologists has not only been the occasion to have an idea on which direction the research is addressed today, but also it pointed out the difficulties of our "scientific hranch." On the basis of the presentations and invited papers we had evidences of a "new" Acarology based on modern techniques and methods of investigations but also the importance, often sheltered even if of relevant value, of the "old" Acarology made on the alpha taxonomy and basic studies. So, a "new" Acarology needs the "old" one. In this context, the hope to put together the European acarologists has been coming up. This fact, of political meaning, can surely improve the acarological movement and the discussion on this point showed clearly the importance of several other activities and efforts in this direction. We hope that the meeting in Siena will represent a significative stone for the progress of Acarology.

It is difficult for me to recollect a time when I was not fascinated with the very notion of a desert. Walt Disney's film, The Living Desert, which I initially saw when I was 8 years of age, provided me with my first glimpse of this wondrous yet seemingly ho stile environment. The images were hypnotic and captivating. I looked on in amazement at the promenade Cl deux of the male and female scorpions during courtship. Their rhythmic and coordinated movements as they grasped one another made them appear to glide in unis on over the surface of the sand, each individual totally absorbed with its partner. In the next minute the fern ale had suddenly and utterly transformed herself like some Jekyll and Hyde act, into an aggressive predator whose prior gregarious embrace was now a hold of death for the male. The indomitable desert grasshopper mouse, the ever sentient kit fox, the graceful shovel-nosed snake swimming in an endless sea of sand.

This is a comprehensive account of centipede biology providing a critical review of the work covering anatomy, behaviour, reproduction and life history, predators and parasites, physiology, ecology and taxonomy. It is an important source-book of particular value to scientists working directly with this group and to soil ecologists and those more generally interested in arthropods, arthropod affinities and their evolution. This is a book from an internationally respected scientist and includes many first-hand accounts of his own work both on temperate and tropical species.

This book synthesizes new information about the environmental advantages of plant resistance, transgenic resistance, the molecular bases of resistance, and the use of molecular markers to map resistance genes. Readers are presented in-depth descriptions of techniques to quantify resistance, factors affecting resistance expression, and the deployment of resistance genes. New information about gene-for-gene interactions between resistant plants and arthropod biotypes is discussed along with the recent examples of using arthropod resistant plants in integrated pest management systems.

This volume contains the Proceedings of the 4th International Conference on Ticks and Tick-borne Pathogens (TTP-4), held in Banff, Alberta, Canada, from 21 to 26 July 2002. TTP-4 continues an important tradition established in 1992 at the first Conference in St. Paul, Minnesota, USA, and developed subsequently at the Kruger National Park, South Africa (1995) and the High Tatra Mountains, Slovakia (1999). The 31 papers published in this special issue are divided between six sessions, with a keynote address as an introduction. The first session, which deals with biosystematics, genomics and proteomics of ticks, contains the most recent world list of valid tick names. The papers deal with a broad range of tick-host-pathogen interactions, including remote sensing and mapping of ticks and tick-borne pathogens as well as practical aspects of tick control. It is recommended reading for anyone working on ticks and tick-borne pathogens, which are of increasing medical and veterinary importance worldwide.

Members of the phylum Echinodermata are among the most familiar marine invertebrates. Forms such as the sea star have become virtually a symbol of sea life. Used in ancient oriental medicine as a source of bioactive compounds, sea cucumbers, sea stars and sea urchins are now used for the extraction and purification of cytotoxic, haemolytic, antiviral, antifungal, antifouling, antimicrobial and even anti-tumoural activities. In addition, of the five extant classes, sea urchins and sea cucumbers are important economic resources for current fishery and aquaculture. Molecular and cell biological techniques described in this book are, on the one hand, indicative of the improvements made over the years and, on the other, stress the need of their further exploitation for the sustainable production of bioactive compounds and their application in biomedicine.

Acanthocephalans, or spiny-headed worms, are endoparasites found in almost all marine, freshwater and terrestrial systems. They infect a huge range of definitive and intermediate hosts during their life cycles, including both vertebrates and arthropods. This volume, first published in 2006, examines the distribution and abundance of the Acanthocephala, and uses this ecological information to reveal the group's enormous survival success. It discusses how the acanthocephalans have evolved differently to all other groups of parasites, and represent a distinct and alternative pathway of parasite evolution and host parasite-interactions. Written for graduate students and researchers in parasitology, ecology and zoology or anyone interested in reading about parasite ecology and evolution.

A thorough understanding of planktonic organisms is the first step towards a real appreciation of the diversity, biology, and ecological importance of marine life. A detailed knowledge of their distribution and community composition is particularly important since these organisms are often very delicate and sensitive to change, and can be used as early indicators of environmental change. Natural and man-induced modification of the environment can affect both the distribution and composition of plankton, with important ecological and economic impacts. Marine Plankton provides a practical guide to plankton biology with a large geographic coverage spanning the North Sea to the north-eastern Atlantic coast of the USA and Canada. The book is divided into three sections: an overview of plankton ecology, an assessment of methodology in plankton research covering sampling, preservation, and counting of samples, and a taxonomic guide richly illustrated with detailed line drawings to aid identification. This is an essential reference text suitable for senior undergraduate and graduate students taking courses in marine ecology (particularly useful for fieldwork) as well as for professional marine biologists. It will also be of relevance and use to environmental scientists, conservation biologists, marine resource managers, environmental consultants, and other specialised practitioners.

One of the main reasons that we organized this edited volume is to increase - ternational awareness of the growing use of invertebrate pathogens for control and eradication of invasive arthropods. As the numbers of invasive species continues to rise, more insect pathologists have been involved with work on their control using entomopathogens. In fact, this is not a new area of focus for insect pathologists; work on microbes against invasive arthropods began more than a century ago with classicalbiologicalcontrolintroductionsofentomopathogenicfungiagainstinvasive species in the 1890s. Chapters in this book cover entomopathogens that have been developedforcontrolofinvasivespeciesovermanydecades(e. g. anematodeagainst Sirex noctilio and Bacillus thuringiensis against gypsy moth) while other chapters focusondevelopmentofcontrolmeasuresforveryrecentinvasives(e. g. emeraldash borer?rstfoundintheUSin2002).

Wehavebeencloselyinvolvedwiththeircontrolusing- crobes, atvaryinglevels(fromlaboratorybenchto?eldstudiestonationalcommittees evaluating eradication programs using the entomopathogen B. thuringiensis). Within the past few years, symposia on use of microbes for invasive control have been organized twice at the annual meetings of the Society of Invertebrate Pathology (2005 - Anchorage, Alaska, and 2007 - Quebec City, Quebec, Canada), demonstrating interest in this subject across the international community of inv- tebrate pathologists. However, no written summaries, covering the different types of pathogens being studied, developed and used for control, have previously - dressed this subje

Pine wilt disease (PWD) is unquestionably a major threat to forest ecosystems worldwide. After seriously affecting Eastern Asian countries, the challenge is now in Europe, following its detection in Portugal in 1999 and its subsequent spread. For foresters, these were really very bad news and, in order for adequate action to be taken, scientists had to teach politicians about the seriousness of the problem. That is never an easy task, but it was successfully done at that time, mainly by the continued effort of Professor Manuel Mota. The challenge of having political decisions based on good science is fundamental for the success of any program, but especially in dif?cult situations such as those arising by the introduction of harmful organisms in new ecosystems. The success of the dialogue between science and policy requires intelligent partners from each side, which is not always necessarily the case... Examples of lack of recognition of problems raised by science are unfortunately abundant throughout the history of science. The recent recognition of the efforts of the Intergovernmental Panel on Climate Change (IPCC) and Al Gore with the - bel Prize, and the continued failure in taking appropriate actions by major political players is a dramatic modern example of the dif?culty of this dialogue...

The Reef Guide documents some 800 reef fishes and invertebrates found along the east and south coasts of southern Africa.

Following on the success of Dennis King’s earlier two titles, this impressive new guide features 578 species of fish and includes sections on anemones, starfish, snails, crabs and shrimps.

Full-colour photographs and descriptive text for each species, along with useful and interesting information, make for easy identification. While focusing on southern Africa, the book is also applicable to the entire east coast of Africa, as well as the islands of the western Indian Ocean – Seychelles, Mauritius, Reunion, Madagascar, the Comoros and the Maldives.

Indispensable for divers, snorkelers and rock-pool enthusiasts, as well as fishermen and marine aquarists.

Interrelationships Between Corals and Fisheries is derived from a workshop held by the Gulf of Mexico Fishery Management Council in Tampa, Florida in May 2013, where world authorities came together to discuss the current problems in managing tropical fisheries and offered suggestions for future directions for both researchers and environmental resource managers. This book addresses current and emerging threats as well as challenges and opportunities for managing corals and associated fisheries. It provides an information baseline toward a better understanding of how corals and the consequences of coral condition influence fish populations, especially as they relate to management of those populations. The book contains content from presentations modified as a result of interactions and discussions with colleagues and peer reviews by global experts in corals and fisheries. Many chapters include additional materials not presented in the workshop. There are also papers that were not presented at the workshop but contribute to the central theme of the book. Topics covered include: Global decline in coral reefs and impacts on fishery yields Distribution and diversity in the Gulf of Mexico Implementation of Coral Habitat Areas of Particular Concern (CHAPCs) Deepwater coral/sponge habitats Coral populations on offshore platforms Mangrove connectivity for sustaining coral reef fisheries Restoring deepwater coral ecosystems and fisheries after the Deepwater Horizon oil spill Predictive mapping of coral reef fish Covering a range of subject matter, most of the chapters offer suggestions for future research on the interrelationships between corals and fisheries. In addition, the final chapter presents a summary on these interrelationships and discusses managing them for the future.

Considerable progress has been made since the 1990s in unravelling the complexities of the snail parasite relationship. The articles in this text cover many different aspects of this subject, including ecology, parasite transmission, parasite interactions, evolutionary biology, molecular systematics and snail-defense systems, emphasizing the topical nature of this important area of parasite biology. Many techniques are now used to investigate the intricacies of host parasite relationships. Genome and post-genomic studies, such as the schistosome genome project, are set to revolutionise parasite biology and unravel molluscan genomes.This volume provides a succinct overview and is intended to generate impetus for future research.

This book is about those animals found on the sea floor that live by filtering microscopic particles carried by water currents. Its purpose is to review what is known about the biology of suspension feeders in relation to their flow environment. The book includes the larval biology, physiology, ethology, and ecology of suspension feeders interacting with water flow. It will be of value to marine scientists beginning research in the new, interdisciplinary field of hydrodynamics and benthic biology, and it is the first attempt to provide a comprehensive overview of this synthesis from the biological viewpoint.

The Mediterranean, Black, and Caspian Seas, the rivers and canals that connect them, and the enormous volume of shipping in the region, represent a conduit for aquatic invasion, whose consequences are only now beginning to be understood. This book provides an up-to-date overview of jelly invasions in the Ponto-Caspian which have affected local ecosystems since the early 1980s, contrasting that with other biological invasions, in search of underlying principles.

Echinoderms and prochordates occupy a key position in vertebrate evolution. The genomes of sea urchin share 70% homology with humans. Researches on cell cycle in sea urchin and phagocytosis in asteroids have fetched Nobel Prizes. In this context, this book assumes immense importance. Echinoderms are unique, as their symmetry is bilateral in larvae but pentamerous radial in adults. The latter has eliminated the development of an anterior head and bilateral appendages. Further, the obligate need to face the substratum for locomotion and acquisition of food has eliminated their planktonic and nektonic existence. Egg size, a decisive factor in recruitment, increases with decreasing depths up to 2,000-5,000 m in lecithotrophic asteroids and ophiuroids but remains constant in their planktotrophics. Smaller (< 18 mm) ophiuroids do not produce a lecithotrophic eggs but larger (> 110 mm) asteroids generate planktotrophic eggs only. Publications on sex ratio of echinoderms indicate the genetic determination of sex at fertilization but those on hybridization, karyotype and ploidy induction do not provide evidence for heterogametism. But the herbivorous echinoids and larvacea with their gonads harboring both germ cells and Nutritive Phagocytes (NPs) have economized the transportation and hormonal costs on gonadal function. Despite the amazing potential just 2 and 3% of echinoderms undergo clonal reproduction and regeneration, respectively. Fission is triggered, when adequate reserve nutrients are accumulated. It is the most prevalent mode of clonal reproduction in holothuroids, asteroids and ophiuroids. However, budding is a more prevalent mode of clonal reproduction in colonial hemichordates and urochordates. In echinoderms, fission and budding eliminate each other. Similarly, autoregulation of early development eliminates clonal reproduction in echinoids and solitary urochordates. In pterobranchs, thaliaceans and ascidians, the repeated and rapid budding leads to colonial formation. Coloniality imposes reductions in species number and body size, generation time and life span, gonad number and fecundity as well as switching from gonochorism to simultaneous hermaphorditism and oviparity to ovoviviparity/viviparity.

The techniques for establishing and maintaining invertebrate tissues and cells in culture remain difficult due to the diversity of invertebrates and their structural and physiological characteristics. Research involving invertebrate cell cultures continues to increase, although the number of cell lines used is still limited. This manual gives detailed descriptions of the technical procedures for the establishment of primary invertebrate cell cultures in vitro. Nutritional requirements, culture media, and species-specific methods for both cell and organ cultures as well as useful techniques for studies on cultured cells are described. The Appendix lists established cell lines available for research with information on the composition of their physiological and nutrient solutions. This comprehensive manual, the first of its kind, is a valuable reference for investigators working with invertebrate cell cultures in academia and industry.

In most terrestrial and aquatic habitats, the vast majority of animals transmitting and receiving communicative signals are arthropods. This book presents the story of how this important group of animals use pheromones, sound, vibration, and light for sexual and social communication. Because of their small to minute body size most arthropods have problems sending and receiving acoustic and optical information, each of which have their own severe constraints. Because of these restraints they have developed chemical signaling which is not similarly limited by scale. Presenting the latest theoretical and experimental findings from studies of signaling, it suggests that close parallels between arthropods and vertebrates reflect a very limited number of solutions to problems in behavior that are available within the confines of physical laws.

This is the third edition of this popular text which reviews all aspects of earthworm biology and ecology. The book has been updated throughout and extensive additions made. These include a greatly expanded treatment of earthworm community ecology, interactions between earthworms and microorganisms, and the importance of earthworms in environmental management and their use in organic waste management. A straightforward and integrative approach has been taken to reviewing the literature of this important area (over 1400 references are cited). An extensive appendix has also been added summarizing the toxicity to earthworms of a wide range of chemicals. This book will continue to be an invaluable text for students of agriculture, soil science, ecology and invertebrate zoology.

The nervous system is particularly fascinating for many biologists because it controls animal characteristics such as movement, behavior, and coordinated thinking. Invertebrate neurobiology has traditionally been studied in specific model organisms, whilst knowledge of the broad diversity of nervous system architecture and its evolution among metazoan animals has received less attention. This is the first major reference work in the field for 50 years, bringing together many leading evolutionary neurobiologists to review the most recent research on the structure of invertebrate nervous systems and provide a comprehensive and authoritative overview for a new generation of researchers. Presented in full colour throughout, Structure and Evolution of Invertebrate Nervous Systems synthesizes and illustrates the numerous new findings that have been made possible with light and electron microscopy. These include the recent introduction of new molecular and optical techniques such as immunohistochemical staining of neuron-specific antigens and fluorescence in-situ-hybridization, combined with visualization by confocal laser scanning microscopy. New approaches to analysing the structure of the nervous system are also included such as micro-computational tomography, cryo-soft X-ray tomography, and various 3-D visualization techniques. The book follows a systematic and phylogenetic structure, covering a broad range of taxa, interspersed with chapters focusing on selected topics in nervous system functioning which are presented as research highlights and perspectives. This comprehensive reference work will be an essential companion for graduate students and researchers alike in the fields of metazoan neurobiology, morphology, zoology, phylogeny and evolution.
