Plant-animal interactions have become a focus of ecological research, with the processes of herbivory being of special interest. This volume examines the interactions of leaf-cutting ants with the rainforest vegetation on Barro Colorado Islands in Central America. It is the synthesis of field research on multiple scales extending over a period of several years. This work can serve as a model study summarizing and extending knowledge about herbivorous insect-plant relationships, and the resulting consequences on structural and functional features of tropical ecosystems. The text is an invaluable reference for researchers and land managers working in the fields of plant-animal interactions, herbivory, community ecology and biodiversity.

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.
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.
This is the first time that a single book has attempted to cover
the whole of the fossil history of insects so comprehensively. The
volume embraces the history of insect palaeontology, methods for
studying fossils, the taphonomic processes leading to their
formation, the diagnostic features of all insect orders, both
extant and extinct, the major fossils of each order, and the
implications that can be drawn from the palaeoentomological record
about past ecology and climates. Many new insights are presented.
Biological control is among the most promising methods for control of pests, diseases and weeds, and this book treats ecological and societal aspects together for the first time. The aim is to evaluate the significance of certain biological properties like biodiversity and natural habitats. In a societal approach terms like 'consumer's attitude', 'risk perception', 'learning and education' and 'value triangle' are recognized as significant for biological production and human welfare.
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).

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...
Insects are often overlooked because they are small or ignored because they are deemed trivial, and many are dismissed as nuisance pests. But their numbers and diversity are mind-numbing, and under even a modest hand lens they are beautiful or bizarre. Insects dominate the centre ground of all terrestrial and most aquatic ecosystems. They inform us of the conservation value of ancient woodland and chalk downland. They help monitor the purity or pollution levels of ponds, streams and rivers. And they can demonstrate the effects of climate change, acting as warning lights to alert us to the damage that humans are doing to the world. Recent insectageddon headlines are starting to make people sit up and take more notice. What better way to promote an interest in these fascinating creatures than by poetizing them? This cornucopia of discordant nonsense, with some quite frankly dubious rhyming clashes, is offered up so that entomological outreach will at least benefit from their shock value.
This volume summarises current developments in integrated pest management (IPM), focussing on insect pests. Chapters discuss advances in understanding species and landscape ecology on which IPM is founded. The book then reviews advances in cultural, physical and, in particular, biological methods of control. Topics include developments in classical, conservation and augmentative biological control as well as the use of entomopathogenic fungi, viruses, nematodes and semiochemicals. The final parts of the book summarise current research on monitoring pesticide use as well as emerging classes of biopesticides.
Mussels represent an important food source in many parts of the world, including Europe, South America and the Far East, and they have considerable potential as a protein source for many developing countries. In addition, mussels are widely used in pollution studies, and in fundamental ecological and physiological investigations. This book, first published in 1976, is a critical review of information on this group of animals, and sets out the material with suggestions for the future direction of research. The subjects covered include the ecology, physiology, biochemistry, genetics and the culture of mussels. It is an important volume, not only for researchers working with marine molluscs, and with mussels in particular, but also for those in the wider fields of marine ecology, comparative physiology and aquaculture.
In this 2006 volume John Murray investigates the ecological processes that control the distribution, abundance and species diversity of benthic foraminifera in environments ranging from marsh to the deepest ocean. To interpret the fossil record it is necessary to have an understanding of the ecology of modern foraminifera and the processes operating after death leading to burial and fossilisation. This book presents the ecological background required to explain how fossil forms are used in dating rocks and reconstructing past environmental features including changes of sea level. It demonstrates how living foraminifera can be used to monitor modern-day environmental change. Ecology and Applications of Benthic Foraminifera presents a comprehensive and global coverage of the subject using all the available literature. It is supported by a website hosting a large database of additional ecological information (www.cambridge.org/0521828392) and will form an important reference for academic researchers and graduate students in Earth and Environmental Sciences.
Arthropods are the most diverse group of organisms on our planet and the tropical rainforests represent the most biologically diverse of all ecosystems. This book, written by 79 authors contributing to 35 chapters, aims to provide an overview of data collected during recent studies in Australia, Africa, Asia, and South America. The book focuses on the distribution of arthropods and their use of resources in the rainforest canopies, providing a basis for comparison between the forest ecosystems of the main biogeographical regions. Topics covered include the distribution of arthropods along vertical gradients and the relationship between the soil/litter habitat and the forest canopy. The temporal dynamics of arthropod communities, habitats and food selection are examined within and among tropical tree crowns, as are the effects of forest disturbance. This important book is a valuable addition to the literature used by community ecologists, conservation biologists entomologists, botanists and forestry experts.
This is the first comprehensive firefly guide for eastern and central North America ever published. It is written for all those who want to know more about the amazing world of lightning bugs and learn the secrets hidden in the flash patterns of the 75+ species found in the eastern and central U.S. and Canada. As an independent researcher working with numerous university teams, naturalist Lynn Frierson Faust, "The Lightning Bug Lady," has spent decades tracking the behavior and researching the habitats of these fascinating creatures. Based on her twenty-five years of field work, this book is intended to increase understanding and appreciation of bioluminescent insects while igniting enthusiasm in a fun and informative way. Species accounts are coupled with historical background and literary epigraphs to engage and draw readers young and old into the world of these tiny sparklers. A chart documenting the flash patterns of the various species will aid in identification. Clear photos illustrate the insects' distinguishing physical characteristics, while habitats, seasonality, and common names are provided in clear, easy-to-understand yet scientifically accurate language. The guide will be welcomed by everyone who wants to learn more about fireflies' and glow-worms' unique traits and about their fragile niche in the ecosystem. FEATURES: Over 600 color photographs Detailed accounts and anatomical diagrams of 75+ species, as well as aids in distinguishing between similar species A first-of-its-kind flash-pattern chart that folds out on heavy-weight paper Extensive scientific details written in an understandable and engaging way Colorful, common names-Twilight Bush Baby, Shadow Ghosts, and Snappy Syncs, and more-for easy species identification based on flash patterns Tips on ideal sites and times of year for firefly watching Conservation-oriented approach
Fleas are one of the most interesting and fascinating taxa of ectoparasites. All species in this relatively small order are obligatory haematophagous (blood-feeding) parasites of higher vertebrates. This book examines how functional, ecological and evolutionary patterns and processes of host-parasite relationships are realized in this particular system. As such it provides an in-depth case study of a host-parasite system, demonstrating how fleas can be used as a model taxon for testing ecological and evolutionary hypotheses. The book moves from basic descriptive aspects, to functional issues and finally to evolutionary explanations. It extracts several general principles that apply equally well to other host-parasite systems, so it appeals not only to flea biologists but also to 'mainstream' parasitologists and ecologists.
Insects are a dominant component of biodiversity in terrestrial ecosystems and play a key role in mediating the relationship between plants and ecosystem processes. This volume examines their effects on ecosystem functioning, focusing mainly, but not exclusively, on herbivorous insects. Renowned authors with extensive experience in the field of plant-insect interactions, contribute to the volume using examples from their own work.
Social behavior occurs in some of the smallest animals as well as some the largest, and the transition from solitary life to sociality is an unsolved evolutionary mystery. In The Evolution of Social Wasps, James H. Hunt examines social behavior in a single lineage of insects, wasps of the family Vespidae. He presents empirical knowledge of social wasps from two approaches, one that focuses on phylogeny and life history and one that focuses on individual ontogeny, colony development, and population dynamics. He also provides an extensive summary of the existing literature while demonstrating how it can be clouded by theory. Hunt's fresh approach to the conflicting literature on sociality highlights how oft repeated models can become fixed in the thinking of the scientific community. Instead, Hunt presents a mechanistic scenario for the evolution of sociality in wasps that changes our perspective on kin selection, the paradigm that has dominated thinking about social evolution since the 1970s. This innovative new model integrates life history, nutrition, fitness and ecology in which social insect biologists will find a rich storehouse of ideas and information, and behavioral ecologists will find a bracing challenge to long accepted models. Engagingly written, bold, and provocative, The Evolution of Social Wasps marks a milestone in our understanding of one of lifes major evolutionary transitions - the origin of social behavior.
Insects represent over half of the planet's biological diversity. This popular textbook provides a comprehensive introduction to this extraordinary diversity, and places entomology central to the theory and practice of evolutionary and ecological studies. Fully revised, this fifth edition opens with a chapter concerning the popular side of insect studies, including insects in citizen science, zoos and butterfly houses, and insects as food for humans and animals. Key features of insect structure, function, behaviour, ecology and classification are integrated with appropriate molecular studies, including the latest international studies. Much of the book is organized around major biological themes: living on the ground, in water, on plants, in colonies, and as predators, parasites/parasitoids and prey insects. A strong evolutionary theme is maintained throughout. There is major revision to the chapter on systematics and taxonomy, and a new chapter, Insects in a Changing World, includes insect responses to, and the consequences of, both climate change and human-assistedglobal alterations to distributions. Updated 'Taxoboxes' demonstrate topical issues and provide conciseinformation on all aspects of each of the 28 major groupings (orders) of insects, plus the three orders of non-insect hexapods. New boxes describe a worrying increase in insect threats to landscape and commercial trees (including eucalypts, palms and coffee) and explain the value of molecular genetic data, including evolutionary developmental biology and DNA barcoding, in insect biodiversity studies.The authors maintain the clarity and conciseness of earlier editions, and extend the profuse illustrations with new hand-drawn figures. Over 50 colour photographs, together with the informative text and an accompanying website with links to video clips, appendices, textboxes and further reading lists, encourage a deeper scientificstudy of insects. The book is intended as the principal text for students studying entomology, as well as a reference text for undergraduate and graduate courses in fields of ecology, agriculture, fisheries and forestry, palaeontology, zoology, and medical and veterinary science.
Wetlands are crucial ecosystems that help filter a great number of toxicants out of the earth's waters. They must be managed and occasionally even built from scratch, including all of the flora and fauna that grows there. Invertebrates play a key role in the wetland food chain. This comprehensive resource is the first dedicated solely to the ecology and management of invertebrates.
Featuring completely updated chapters, additional authors, and an increased emphasis on alternatives to traditional pesticides, the second edition of Ecological Entomology is the field's leading reference on the role of insects in ecosystems. The authors cover insect growth and development, what they eat, how they reproduce, and how they move in various environments. The book also examines how insects interact with the plant community and how to control insect populations naturally.
This book is a detailed account of the embryology, growth and metamorphosis of mosquitoes, the nutrition of larvae and adults, and egg production by the adult females. Physiological adaptations of larvae to their aquatic environment are also described. Written in a manner to be comprehensible to any informed biologist, the book has received glowing reviews.
This book addresses these topical issues and is based on a Discussion Meeting held at the Royal Society, London, in April 1998. Contributors include scientists from leading research groups in Europe, North America, Asia and Australia. The papers have also been published as an issue of the journal Philosophical Transactions: Biological Sciences, published by the Royal Society. Topics covered include molecular genetics, mechanisms, ecological genetics and management. There is also discussion of the genetically delivered toxicant derived from the insect pathogen Bacillus thuringiensis. The book is essential reading for agricultural, medical and veterinary entomologists concerned with pest management.
Our highly seasonal world restricts insect activity to brief portions of the year. This feature necessitates a sophisticated interpretation of seasonal changes and enactment of mechanisms for bringing development to a halt and then reinitiating it when the inimical season is past. The dormant state of diapause serves to bridge the unfavourable seasons, and its timing provides a powerful mechanism for synchronizing insect development. This book explores how seasonal signals are monitored and used by insects to enact specific molecular pathways that generate the diapause phenotype. The broad perspective offered here scales from the ecological to the molecular and thus provides a comprehensive view of this exciting and vibrant research field, offering insights on topics ranging from pest management, evolution, speciation, climate change and disease transmission, to human health, as well as analogies with other forms of invertebrate dormancy and mammalian hibernation.
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. |
