Available in PDF, EPUB and Kindle. Book excerpt: Speciation is one of the great themes of evolutionary biology. It is the process through which new species are born and diversity generated. Yet for many years our understanding of the process consisted of little more than a perception that if populations are isolated geographically, they will diverge genetically and may come to form new species. This situation began to change in the 1960s as an increasing number of biologists challenged the exclusivity of allopatric speciation and began to probe more deeply into the actual process by which divergence occurs and reproductive isolation is acquired. This focus on process led to many new insights, but numerous questions remain and speciation is now one of the most dynamic areas of research in modern evolutionary biology. This volume presents the newest research findings on speciation bringing readers up to day on species concepts, modes of speciation, and the nature of reproductive barriers. It also discusses the forces that drive divergence of populations, the genetic control of reproductive isolation, and the role played by hybrid zones and hybridization in speciation.

Book Synopsis Tropical Biology and Conservation Management - Volume 7 by : Kleber Del Claro
Download or read book Tropical Biology and Conservation Management - Volume 7 written by Kleber Del Claro and published by EOLSS Publications. This book was released on 2009-05-11 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Encyclopedia of Tropical Biology and Conservation Management is a component of the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty one Encyclopedias. Tropical environments cover the most part of still preserved natural areas of the Earth. The greatest biodiversity, as in terms of animals and plants, as microorganisms, is placed in these hot and rainy ecosystems spread up and below the Equator line. Additionally, the most part of food products, with vegetal or animal origin, that sustain nowadays human beings is direct or undirected dependent of tropical productivity. Biodiversity should be looked at and evaluated not only in terms of numbers of species, but also in terms of the diversity of interactions among distinct organisms that it maintains. In this sense, the complexity of web structure in tropical systems is a promise of future to nature preservation on Earth. In the chemicals of tropical plant and animals, could be the cure to infinite number of diseases, new food sources, and who knows what more. Despite these facts tropical areas have been exploited in an irresponsible way for more than 500 years due the lack of an ecological conscience of men. Exactly in the same way we did with temperate areas and also tropical areas in the north of Equator line. Nowadays, is estimated that due human exploitation, nation conflicts and social problems, less than 8% of tropical nature inside continental areas is still now untouchable. The extension of damage in the tropical areas of oceans is unknown. Thus so, all knowledge we could accumulate about tropical systems will help us, as in the preservations of these important and threatened ecosystems as in a future recuperation, when it was possible. Only knowing the past and developing culture, mainly that directed to peace, to a better relationship among nations and responsible use and preservation of natural resources, human beings will have a long future on Earth. These volumes, Tropical Biology and Natural Resources was divided in sessions to provide the reader the better comprehension possible of issue and also to enable future complementation and improvements in the encyclopedia. Like we work with life, we intended to transform this encyclopedia also in a “life” volume, in what new information could be added in any time. As president of the encyclopedia and main editor I opened the theme with an article titled: “Tropical Biology and Natural resources: Historical Pathways and Perspectives”, providing the reader an initial view of the origins of human knowledge about the tropical life, and what we hope to the future. In the sequence we have more than 100 chapters distributed in tem sessions: Tropical Ecology (TE); Tropical Botany (TB); Tropical Zoology (TZ); Savannah Ecosystems (SE); Desert Ecosystems (DE); Tropical Agriculture (TA); Natural History of Tropical Plants (NH); Human Impact on Tropical Ecosystems (HI); Tropical Phytopathology and Entomology (TPE); Case Studies (CS). This 11-volume set contains several chapters, each of size 5000-30000 words, with perspectives, applications and extensive illustrations. It is the only publication of its kind carrying state-of-the-art knowledge in the fields of Tropical Biology and Conservation Management and is aimed, by virtue of the several applications, at the following five major target audiences: University and College Students, Educators, Professional Practitioners, Research Personnel and Policy Analysts, Managers, and Decision Makers and NGOs.

Available in PDF, EPUB and Kindle. Book excerpt: "This volume captures the state-of-the-art in the study of insect-plant interactions, and marks the transformation of the field into evolutionary biology. The contributors present integrative reviews of uniformly high quality that will inform and inspire generations of academic and applied biologists. Their presentation together provides an invaluable synthesis of perspectives that is rare in any discipline."--Brian D. 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

Book Synopsis Cladistic Analysis of North American Platynini and Revision of the Agonum Extensicolle Species Group (Coleoptera, Carabidae) by : James Kenneth Liebherr
Download or read book Cladistic Analysis of North American Platynini and Revision of the Agonum Extensicolle Species Group (Coleoptera, Carabidae) written by James Kenneth Liebherr and published by Univ of California Press. This book was released on 1986-01-01 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cladistic analysis based on internal male female reproductive characters and external characters is used to group exemplar taxa in the carabid tribe Platynini. A classification, key to genera in North America, and a key to species groups of Agonum in North America north of Mexico are presented. The Agonum extensicolle species group comprises seven species: A. cyanope (Bates); A. extimum Liebherr, n.sp.; A. parextimum Liebherr n. sp.; A. texanum (LeConte); A. extensicolle (Say); A. decorum (Say); A. elongatulum (Dejean). Analyses of infraspecific geographic variation show: 1 ) A. texanum is biometrically uniform over the center of its range whereas individuals from outlying populations deviate in several measurements; 2) A. extensicolle is a variable species, with clinal changes in biometry and color ocurring across its range; 3) A. decorum is polymorphic for color and setation, and clinally variable in biometric characters. Across the group, flight apparatus development is inversely correlated with the amount of genetic heterogeneity measured by starch-gel electrophoresis. Electrophoretic, qualitative morphological, and biometric data are used to estimate phylogenetic relationships in the A. extensicolle group. The electrophoretic and morphological data produce compatible estimates of phylogeny. The biometric data are incompatible with the other data and are judged less useful for estimation of affinities. Distributional data are utilized in conjunction with the proposed phylogeny to investigate speciation events in the group. The principal mechanism is allopatric speciation brought about by vicariance across the lowlands of southeastern Arizona; the Cochise filter barrier. A second pattern involves a peripheral isolate of Antillean stock diverging on the Florida peninsula. A third speciation event involves a habitat shift in which a lowland desert form produced a species which now inhabits the pine-oak zone in the Sierra Madre Occidental. The area-taxon relationships are compared with those in other groups. Based on an electrophoretic clock calibrated using data from Drosophila, the timing of the initial speciation event in the group is estimated at 6-12 million years b.p. Other speciation events occurred throughout the Pliocene and Pleistocene, with the most recent divergence of A. decorum and A. elongatulum estimated at less than two million years b.p.
