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 2018-07-12 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Black Hills, straddling the border between southwestern South Dakota and northeastern Wyoming, represent an ecological "island" of mountainous terrain in the midst of the Great Plains. Streams, rivers, lakes, and ponds are abundant, yet the aquatic insect fauna inhabiting those ecosystems has not previously been compiled in a single document. This work demonstrates that the known fauna of 95 families, 335 genera, and 447 species-level aquatic insect taxa has a curious mix of eastern, western, northern, and southern biogeographic affinities, yet many significant data gaps remain, and this work can only represent a starting point. The Black Hills beckon more curious naturalists to come and add to our knowledge.

Book excerpt: The First Edition of Ecology and Classification of North American Freshwater Invertebrates has been immensely popular with students and researchers interested in freshwater biology and ecology, limnology, environmental science, invertebrate zoology, and related fields. The First Edition has been widely used as a textbook and this Second Edition should continue to serve students in advanced classes. The Second Edition features expanded and updated chapters, especially with respect to the cited references and the classification of North American freshwater invertebrates. New chapters or substantially revised chapters include those on freshwater ecosystems, snails, aquatic spiders, aquatic insects, and crustaceans. Most up-to-date and informative text of its kind Written by experts in the ecology of various invertebrate groups, coverage emphasizes ecological information within a current taxonomic framework Each chapter contains both morphological and taxonomic information, including keys to North American taxa (usually to the generic level) as well as bibliographic information and a list of further readings The text is geared toward researchers and advanced undergraduate and graduate students
