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.

This book was released on 2012-11-28 with total page 1736 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication provides a comprehensive review of the nomenclature and distribution of the Geadephaga of America, north of Mexico. Overall 2439 valid species-group taxa in 208 genera are catalogued along with their synonyms. Besides the usual information pertaining to author(s), date and page of publication, the type locality, location of name-bearing type, first reference establishing each synonym, and etymology for many patronymic names are provided for species-group names. Genus-group names are listed with the author(s), year of publication, page citation, type species with manner of fixation and etymology for most. The geographical distributions of all species-group taxa are briefly summarized and their state and province records are indicated. About 2500 references are listed with publication dates for many in order to assess priority of names.Several new nomenclatural acts are introduced including one new genus-group taxon, one new replacement name, three changes in precedence, five new genus-group synonymies, 65 new species-group synonymies, one new species-group status, and 12 new combinations.The work includes also a discussion of the notable private North American carabid collections, a synopsis of all extant world geadephagan tribes and subfamilies, a brief faunistic assessment of the fauna, a list of North American fossil Geadephaga, a list of North American Geadephaga larvae described or illustrated, a list of species described from specimens mislabeled as from North America, and a list of unavailable names listed from North America.

Download or read book Soil Biology Guide written by Daniel L. Dindal and published by John Wiley & Sons. This book was released on 1991-01-16 with total page 1381 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive study of the biology, taxonomy, and ecology of each of the soil biotic groups. The first chapter presents an ecological approach to soil studies. The remaining 42 chapters provide specific information on each of the taxonomic groupings. Contains illustrated identification keys to each group. Some keys go by functional morphological delineations; others lead the reader to classical identification at family, genus, or species levels. Some incorporate descriptions of new genera and species. Especially useful for the study of mesic, xeric, and hydric terrestrial sites. Includes an extensive bibliography.

Available in PDF, EPUB and Kindle. Book excerpt: Australia and New Zealand boast an active community of scholars working in the field of history, philosophy and social studies of science. • Australasian Studies in History and Philosophy of Science' aims to provide a distinctive publication outlet for their work. Each volume comprises a group of essays on a connected theme, edited by an Australian or a New Zealander with special expertise in that particular area .. In each volume, a majority of the contributors is from Australia or New Zealand. O;mtributions from elsewhere are by no means ruled out, however, and are indeed actively encouraged wherever appropriate to the balance of the volume in question. Earlier volumes in the series have been welcomed for significantly advancing the discussion of the topics they have dealt with. The present volume will I believe be greeted equally enthusiastically by readers in many parts of the world. R. W.
