Farrell, Professor of Organismic and Evolutionary Biology, Harvard University "Tilmon has assembled a truly wonderful and rich volume, with contributions from the lion's share of fine minds in evolution and ecology of herbivorous insects. The topics comprise a fascinating and deep coverage of what has been discovered in the prolific recent decades of research with insects on plants. Fascinating chapters provide deep analyses of some of the most interesting research on these interactions. From insect plant chemistry, behavior, and host shifting to phylogenetics, co-evolution, life-history evolution, and invasive plant-insect interaction, one is hard pressed to name a substantial topic not included. This volume will launch a hundred graduate seminars and find itself on the shelf of everyone who is anyone working in this rich landscape of disciplines."--Donald R. Strong, Professor of Evolution and Ecology, University of California, Davis "Seldom have so many excellent authors been brought together to write so many good chapters on so many important topics in organismic evolutionary biology. Tom Wood, always unassuming and inspired by living nature, would have been amazed and pleased by this tribute."--Mary Jane West-Eberhard, Smithsonian Tropical Research Institute

Available in PDF, EPUB and Kindle. Book excerpt: Radiations, or Evolution in Action We have just celebrated the “Darwin Year” with the double anniversary of his 200th birthday and 150th year of his masterpiece, “On the Origin of Species by means of Natural Selection”. In this work, Darwin established the factual evidence of biological evolution, that species change over time, and that new organisms arise by the splitting of ancestral forms into two or more descendant species. However, above all, Darwin provided the mechanisms by arguing convincingly that it is by natural selection – as well as by sexual selection (as he later added) – that organisms adapt to their environment. The many discoveries since then have essentially con?rmed and strengthened Darwin’s central theses, with latest evidence, for example, from molecular genetics, revealing the evolutionary relationships of all life forms through one shared history of descent from a common ancestor. We have also come a long way to progressively understand more on how new species actually originate, i. e. on speciation which remained Darwin’s “mystery of m- teries”, as noted in one of his earliest transmutation notebooks. Since speciation is the underlying mechanism for radiations, it is the ultimate causation for the biological diversity of life that surrounds us.
Book Synopsis Evolutionary Ecology across Three Trophic Levels by : Warren G. Abrahamson
Download or read book Evolutionary Ecology across Three Trophic Levels written by Warren G. Abrahamson and published by Princeton University Press. This book was released on 2020-03-31 with total page 478 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a work that will interest researchers in ecology, genetics, botany, entomology, and parasitology, Warren Abrahamson and Arthur Weis present the results of more than twenty-five years of studying plant-insect interactions. Their study centers on the ecology and evolution of interactions among a host plant, the parasitic insect that attacks it, and the suite of insects and birds that are the natural enemies of the parasite. Because this system provides a model that can be subjected to experimental manipulations, it has allowed the authors to address specific theories and concepts that have guided biological research for more than two decades and to engage general problems in evolutionary biology. The specific subjects of research are the host plant goldenrod (Solidago), the parasitic insect Eurosta solidaginis (Diptera: Tephritidae) that induces a gall on the plant stem, and a number of natural enemies of the gallfly. By presenting their detailed empirical studies of the Solidago-Eurosta natural enemy system, the authors demonstrate the complexities of specialized enemy-victim interactions and, thereby, the complex interactive relationships among species more broadly. By utilizing a diverse array of field, laboratory, behavioral, genetic, chemical, and statistical techniques, Abrahamson and Weis present the most thorough study to date of a single system of interacting species. Their interest in the evolutionary ecology of plant-insect interactions leads them to insights on the evolution of species interactions in general. This major work will interest anyone involved in studying the ways in which interdependent species interact.
Book Synopsis Phenotypic Plasticity of Cuticular Hydrocarbons in Herbivorous Insects by : Tobias Otte
Download or read book Phenotypic Plasticity of Cuticular Hydrocarbons in Herbivorous Insects written by Tobias Otte and published by . This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Speciation of herbivorous insects may be driven by specialization on host plants. Plasticity in host plant preferences might promote sympatric speciation of herbivorous insects if plants affect mating signals and thus, lead to assortative mating. The general aim of this thesis is to understand the causes and consequences of phenotypic plasticity of mating recognition systems of herbivorous insects. The investigated species are the syntopic leaf beetles Phaedon cochleariae and P. armoraciae which have a common host plant range, but use divergent host species when occurring at the same site. Their sexual behavior is mediated by their cuticular hydrocarbon (CHC) profiles which function as contact pheromones for mate and species recognition. Behavioral bioassays and chemical analyses are used to study the question whether the host plant species affects the CHC pattern of the beetles, and thus, their mate recognition. Within a species, males prefer mating with females feeding on the same host plant species to mating with females feeding on an alternative host plant. Sexual isolation between species ceases when beetles feed upon the same host plant species. A discriminant analysis reveals that the beetles' quantitative composition of CHC profiles clearly differ in dependence of sex, host plant and insect species. However, the profiles of the two beetle species are more similar when feeding upon the same host plant species. These findings give rise to the idea that plant-induced phenotypic divergence in mate recognition cues of herbivorous insects may act as an early barrier to gene flow between insect populations on different host species, thus preceding genetic divergence and thus, promoting ecological speciation
Book Synopsis Evolution of Insect Migration and Diapause by : Hugh Dingle
Download or read book Evolution of Insect Migration and Diapause written by Hugh Dingle and published by Springer. This book was released on 1978-04-11 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is an outgrowth of a Symposium entitled "Evolution of Escape in Space and Time" held at the XV International Congress of Entomology in Washington, D. C., USA in August, 1976. The choice of topic was prompted by recent advances in evolutionary ecology and the apparent suitability of insect migration and dia pause as appropriate material for evolutionary studies. In the event, that choice seems amply justified as I hope a perusal of these papers will show. These Sympos ium papers hardly cover the topic of the evolution of escape mechanisms exhaustively, and I am sure everyone will have his favorite lacuna. Some of the more obvious ones are indicated by Professor Southwood in his Concluding Remarks at the end of the book. The purpose of the Symposium, however, was not complete coverage, but rather to indicate the potential inherent in insect migration and diapause for the study of evolutionary problems. In that I think we have succeeded reasonably well. These papers are expanded and in some cases somewhat altered versions of the papers delivered in Washington. This has allowed greater coverage of the topics in question. I suggested a format of a general overview of a topic emphasizing the author's own research con tributions. In general the papers follow this outline although emphases vary. Two of the authors, Dr. Rainey and Dr. Lumme, were unable to attend the Symposium. Dr. Rainey's paper was read by Mr. Frank Walsh, but Dr.
Book Synopsis Major Evolutionary Radiations by : Paul D. Taylor
Download or read book Major Evolutionary Radiations written by Paul D. Taylor and published by Clarendon Press. This book was released on 1990 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: This unique volume takes a close look at patterns of evolutionary change responsible for the astounding diversity of life and the major radiations seen in many taxonomic groups. Evidence from the fossil record shows that this process has not occurred at an even rate. Rather, relatively short but highly active periods of evolution have yielded the multiplication of species and morphological divergences, such as the emergence of flowering plants during the late Cretaceous. The contributors to this work, all recognized authorities in their fields, discuss general aspects of major radiations, and then focus on evolution in taxonomic groups with ample fossil records. The book is an important complement to the literature of extinction and paleontology, and will be read with interest by paleontologists and evolutionary biologists alike.
Book Synopsis Coevolution of Life on Hosts by : Dale H. Clayton
Download or read book Coevolution of Life on Hosts written by Dale H. Clayton and published by University of Chicago Press. This book was released on 2016 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: For many of us, the mere mention of lice forces an immediate hand to the head, and recollection of childhood experience with nits, special shampoos, etc. But for a certain breed of biologist, lice make for fascinating scientific fodder, especially so if you are a scientist studying coevolution. Lice and their various hosts--humans, birds, etc. --provide a stunning example of the ecology of species coevolution. This system of complex symbiotic relations reveals some of the ecological principles of coevolutionary relations, one of the most exciting areas of research in evolutionary biology of recent. This work provides an introduction to coevolutionary concepts and approaches, ranging from microevolutionary (ecological) time to macroevolutionary time. The authors then use the system of parasitic lice and their hosts to illustrate some of these different concepts and approaches. They draw examples from a variety of other coevolving systems for comparative purposes, and emphasize the integration of cophylogenetic, comparative, and experimental data in testing coevolutionary hypotheses. Because lice are permanent parasites that spend their entire lifecycle on the body of the host, their close ecological association makes them ideally suited for this kind of synthetic overview of coevolution."

Book Synopsis Insects and Other Arthropods of Tropical America by : Paul E. Hanson
Download or read book Insects and Other Arthropods of Tropical America written by Paul E. Hanson and published by Cornell University Press. This book was released on 2016-06-15 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: Visitors to tropical forests generally come to see the birds, mammals, and plants. Aside from butterflies, however, insects usually do not make it on the list of things to see. This is a shame. Insects are everywhere, they are often as beautiful as the showiest of birds, and they have a fascinating natural history. With their beautifully illustrated guide to insects and other arthropods, Paul E. Hanson and Kenji Nishida put the focus on readily observable insects that one encounters while strolling through a tropical forest in the Americas. It is a general belief that insects in the tropics are larger and more colorful than insects in temperate regions, but this simply reflects a greater diversity of nearly all types of insects in the tropics. On a single rainforest tree, for example, you will find more species of ant than in all of England. Though written for those who have no prior knowledge of insects, this book should also prove useful to those who study them. In addition to descriptions of the principal insect families, the reader will find a wealth of biological information that serves as an introduction to the natural history of insects and related classes. Sidebars on insect behavior and ecological factors enhance the descriptive accounts. Kenji Nishida’s stunning photographs—many of which show insects in action in their natural settings—add appeal to every page. A final chapter provides a glimpse into the intriguing world of spiders, scorpions, crabs, and other arthropods.
Book Synopsis Origins, Diversity, and Diversification of the Native Hawaiian Leafhoppers (Hemiptera by : Gordon M. Bennett IV
Download or read book Origins, Diversity, and Diversification of the Native Hawaiian Leafhoppers (Hemiptera written by Gordon M. Bennett IV and published by . This book was released on 2012 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: The relationship between plants and insects is one of the greatest evolutionary stories in the history of life on earth. Their importance in global terrestrial ecosystem functioning is self evident, as both represent the most abundant life on the planet. While plant-insect interactions have received much attention and are easily manipulated in experimental investigations, there have been few broad-scale phylogenetic studies for circumscribed herbivorous groups. As a result, the evolutionary role of interspecific interactions in promoting herbivorous insect diversification, at both the global and local scales, remains unclear. Remarkably, one of the largest gaps in our evolutionary and ecological understanding includes the sap-feeding insects in the Auchenorrhyncha suborder (Hemiptera), which contain some of the largest, terrestrially dominant host-plant restricted insect groups known (e.g., Cicadas, planthoppers, and leafhoppers). The evolutionary success of Auchenorrhyncha is due, at least in part, to ancient associations with a consortium obligate bacterial endosymbionts that have persisted for over 260 million years. However, like their insect hosts, the diversity and evolutionary relationships of endosymbiont associations remain relatively unknown for most aucchenorrhynchan groups. The leafhoppers (Cicadomorpha: Cicadellidae) remain one of the largest, yet poorly understood insect families. Of the 22,000 currently described species, thousands remain to be described with an overall unknown diversity (some estimates suggest as many as 90% of tropical Cicadomorpha remain to be described). This is surprising, since they offer excellent models to understand ecological and biogeographic mechanisms of species diversification due to their strict host-plant specificity, limited dispersal, and high rates of local endemism. The cicadellid subfamily, Deltocephalinae, represents the largest leafhopper groups, yet their patterns of species diversification, host-plant use, and endosymbiont associations remain almost entirely unknown. This study used the Hawaiian Archipelago as a model system to investigate the roles of ecology, biogeography, and endosymbiont interactions in the diversification of the native Hawaiian leafhopper genus, Nesophrosyne (Cicadellidae: Deltocephalinae). The Hawaiian Islands offer a tractable natural laboratory to circumscribe and study plant-insect evolution due to their isolated, discrete and replicated nature, and high levels of endemism. Nesophrosyne represents one of the most diverse and ecologically dominant herbivore radiations on Hawaii, but has eluded scientific attention for over 60 years. Species are obligate phloem feeders and are highly host-plant specific. Moreover, Nesophrosyne exhibits the quintessential characteristics of an adaptive radiation, including dramatic morphological adaptations to the endemic Hawaiian flora and adaptive diversification across the archipelago to fill habitat types from coastal to sub-alpine regions. The specific goals of this study were to 1) update the current taxonomic status of Nesophrosyne, 2) determine the diversity and phylogenetic relationships of species in the genus, 3) infer the roles of ecology and geology in the adaptive radiation, historical biogeography, and species diversification dynamics of Nesophrosyne, and 4) to reconstruct the global relationships of the dual obligate bacterial endosymbionts of Nesophrosyne and their rates of evolution. In the first chapter, the taxonomic history and status of Nesophrosyne was reviewed. The genus was redescribed, and the subgenus Nesoreias was synonymized with Nesophrosyne. Eight new species associated with the widespread host-plant species, Broussaisia arguta (Hydrangeaceae), were described. Results reveal morphologically cryptic diversity according to individual Hawaiian Islands and volcanoes within this group. A model usage of morphological and molecular characters was developed for future delimitation of species in Nesophrosyne. The second chapter reconstructed a comprehensive phylogeny for Nesophrosyne in order to determine the origins, species diversity, and host-plant use of the native Hawaiian leafhoppers. Results support a monophyletic Nesophrosyne, originating from the Western Pacific basin, with a sister-group relationship to the genus Orosius. Nesophrosyne species are characterized by high levels of morphologically cryptic diversity and local endemicity, comprising> 200 species. Species demonstrate four dominant patterns of host-plant specialization that shape species diversity: 1) diversification through host switching; 2) specialization on widespread hosts with allopatric speciation; 3) repeated, independent shifts to the same hosts; and, 4) absence or low abundance on some hosts, suggesting herbivore interactions may limit ecological opportunity. The third chapter inferred the roles of ecology and geology in the adaptive radiation, historical biogeography, and species diversification dynamics of Nesophrosyne. The molecular age of Nesophrosyne indicates a split from Orosius 4.5 million years ago (Ma), with a basal divergence on Hawaii 3.2 Ma. The genus originated on Kauai and subsequently colonized younger islands as they formed. Ancestral host-plant reconstructions reveal that the plant families, Urticaceae and Rubiaceae, played important roles in the early diversification of Nesophrosyne. Results indicate that island geography have imposed significant barriers to continued gene flow, leading to extensive allopatric speciation and intra-island diversification. Finally, Nesophrosyne diversification dynamics show an initial burst in speciation rates, with a subsequent diversity-dependent decline, corresponding to island formation. Finally, chapter four examined the global relationships of Nesophrosyne's dual obligate, bacteriome restricted bacterial endosymbionts, Candidatus Sulcia muelleri' and a novel ß-proteobacterium in the Ca. Nasuia' genus. A global bacterial phylogeny was reconstructed, revealing a shared origin for the ß-proteobacterial lineages throughout Deltocephalinae genera, and potentially throughout Auchenorrhyncha. The bacteriome association and transovarial transmission of Nesophrosyne's endosymbionts were confirmed using Fluorescent in situ Hybridization techniques. Finally, inference of absolute molecular rates demonstrates highly elevated rates of molecular evolution - the fastest so far recorded. We propose a second species in the genus Nasuia to describe the novel ß-proteobacterium in Nesophrosyne. Hawaii has long been held as a model system to understand adaptive radiation and evolutionary biology, however my study is one of the first to test these patterns directly for a hyper-diverse endemic insect radiation, and for the suborder Auchenorrhyncha. The presented results illustrate that, in diverse herbivorous groups, multiple evolutionary processes play fundamental roles in species diversification, including associations with bacterial endosymbionts, host-plant specialization, insect-insect interactions, and the geologic formation of islands. These results develop both an understanding of how ecological and geological controls shape adaptive diversification in insects, and a general model for contextualizing species diversification in herbivorous insects.
Book Synopsis Genetic Structure and Local Adaptation in Natural Insect Populations by : Susan Mopper
Download or read book Genetic Structure and Local Adaptation in Natural Insect Populations written by Susan Mopper and published by Springer. This book was released on 2013-03-06 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Providing an essential foundation for evolutionary theory, this comprehensive volume examines patterns of genetic variation within natural insect populations, and explores the underlying mechanisms that lead to the genetic divergence of coexisting organisms. In particular, the text investigates current research on finescale genetic structure in natural insect populations. Internationally renowned scientists offer a wealth of current information not previously published. Part I present case studies of adaptive genetic structure in natural insect populations, including a critical discussion of the strenghts and weaknesses of the experimental methods employed. Part II addresses the ecological mechanisms that produce adaptive genetic structure in natural insect populations. Part III describes how behavioral and life-history patterns influence genetic structure. Finally, Part IV combines theoretical and empirical approaches linking genetic structure at the population level with larger-scale patterns of variation, such as host race formation and speciation. This broad-ranging, interdisciplinary source of information supplies a thorough examination of the mechanisms that promote and impede genetic structure in natural insect populations. It is a book that will be of interest to undergraduate and graduate students, and to researchers in the fields of ecology, evolution, insect and plant systems, entomology, and population genetics.
