Download or read book Biogeography and Taxonomy of Honeybees written by Friedrich Ruttner and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Honeybees are as small as flies or as large as hornets, nesting in nar row cavities of trees and rocks or in the open on large limbs of trees 30 m above ground. They occur in tropical zones and in the forests of the Ural mountains, they survive seven months of winter and even longer periods of drought and heat. Historically, they lived through a extended time of stagnation in the tropics from the mid-Tertiary, but then experienced an explosive evolution during the Pleistocene, re sulting in the conquest of huge new territories and the origin of two dozen subspecies in Apis mellifera. This vast geographic and ecologic diversification of the genus Apis was accompanied by a rich morphological variation, less on the level of species than at the lowest rank, the subspecies level. Variation being exclusively of a quantitative kind at this first step of speciation, tradi tional descriptive methods of systematics proved to be unsatisfactory, and honeybee taxonomy finally ended up in a confusing multitude of inadequately described units. Effective methods of morphometric-sta tistical analysis of honeybee popUlations, centered on limited areas, have been developed during the last decades. Only the numerical characterization of the populations, together with the description of behavior, shows the true geographic variability and will end current generalizations and convenient stereotypes.
Download or read book The oil collecting bees of Centris Melanocentris Hymenoptera Apidae written by Felipe Vivallo and published by Felipe Vivallo. This book was released on 2022-04-15 with total page 536 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Neotropical Region is one of the most diverse places in the world. In this region are found most of the lineages of bees that collect floral oils, a unique characteristic among insects. The genus Centris is an extensive group of this type of bees, which are distributed from the United States to Patagonia, in the extreme south of South America. The largest, most striking, colorful and beautiful species of the genus are found in the humid forests of South America, all of them forming part of the subgenus Centris (Melanocentris). This book brings a taxonomic review of all the species of this subgenus, including the description of numerous species hitherto unknown to science. Along with the description of these species, the new subgenus Centris (Odontoxys) is also described, which contains species that are distributed from Mexico to Argentina. The book also includes redescriptions and photographs of both sexes of all species, along with distribution maps, an identification key, and lists of material examined and of floral hosts.
Download or read book The oil collecting bees of Centris Paracentris Hymenoptera Apidae written by Felipe Vivallo and published by Felipe Vivallo. This book was released on 2020-12-01 with total page 379 pages. Available in PDF, EPUB and Kindle. Book excerpt: Centris (Paracentris) Cameron is one of the most specious and morphologically diverse subgenera of the bee genus Centris Fabricius. These two features, along with the lack of modern taxonomic revisions make this group one of the lineages with the greatest taxonomic problems within Centridini. Partial revisions of groups of species from North and South America have been published, but none comprehensively studying all species described. In this book are studied all species of Centris (Paracentris) for the first time, providing diagnoses and redescriptions of both sexes. The following twenty one species are described as new: C. aenigmatica sp. nov., C. agyniax sp. nov., C. areequipensis sp. nov., C. aymara sp. nov., C. bagualis sp. nov., C. caribensis sp. nov., C. comonoxa sp. nov., C. diaguita sp. nov., C. euctenoda sp. nov., C. hexirrhina sp. nov., C. inca sp. nov., C. mexicanaides sp. nov., C. milluni sp. nov., C. multistriata sp. nov., C. niveiceps sp. nov., C. rasmusseni sp. nov., C. rozeni sp. nov., C. sacsayhuaman sp. nov., C. tayabamba sp. nov., C. xenopoda sp. nov., and C. yawar sp. nov., mainly from the South American Andes, including the first species recorded from the Caribbean. Centris satana Snelling is proposed as new junior synonym of C. laevibullata Snelling. In addition, the male of C. cisnerosi (Cockerell) and the female of C. euphenax Cockrell are described for the first time. An identification key, figures, maps, new distribution records, floral hosts, and an updated catalog for all species of the subgenus are also provided.

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.
