Available in PDF, EPUB and Kindle. Book excerpt: Ledrinae represent a relatively small subfamily within the very large and diverse leafhopper family Cicadellidae. Prior to this study, the subfamily contained approximately 450 species in 5 tribes and 73 genera distributed worldwide, but primarily in Australia, Africa, and the Indomalayan region. Several authors have suggested Ledrinae are not monophyletic, and recent studies based on molecular and morphological data have called the existing classification into question. The goals of this study were to collect and analyze morphological data under rigorous phylogenetic criteria in order to test the monophyly of Ledrinae, provide robust definitions for the subfamily and its tribes, and provide a phylogenetic framework for understanding relationships among these leafhoppers. New phylogenetic hypotheses are presented here regarding the monophyly of Ledrinae and its included tribes. A total of 235 morphological characters were coded for 60 species from 31 genera in the tribes Ledrini and Petalocephalini, 5 species from the tribes Stenocotini, Thymbrini, and Xerophloeini, and 10 species selected as outgroups from various other cicadellid subfamilies. Data were analyzed in PAUP* and resulted in a single completely resolved topology with many well-supported nodes. Ledrinae, as previously defined, was found to be polyphyletic with respect to Stenocotini, Thymbrini, and various ledrine genera, which were placed with the outgroup taxa. Stenocotini and Thymbrini were placed with Tartessinae, agreeing with results of other recent studies. Rubria, Hespenedra, and the Afrorubria genus group formed independent lineages within Ledrinae. Xerophloeini was placed as a basal lineage within Ledrinae closely associated with the Afrorubria group. Ledrini and Petalocephalini, as previously defined, did not form monophyletic lineages, but were randomly interspersed with respect to one another. Stenocotini and Thymbrini are here removed to the subfamily Tartessinae, and Petalocephalini is mad.

This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This research examines the phylogeny of the tribes of the leafhopper subfamily Typhlocybinae using both morphological, 73 binary and multistate characters, and molecular, 16S rDNA and Histone (H3), evidence. Seventy-five taxa were included in the morphological study, and 48 were included in the molecular analysis. The combined, total evidence, analysis used 48 taxa common to both sets of data. Results of the total evidence analyses suggested 4 tribes with the following topology: Alebrini + (Empoascini + Typhlocybini) + (Dikraneurini including subtribe Erythroneurina). This topology does not completely resemble any of the last century's major typhlocybine works, but comes closest to Dr. Young's 1952 work. Based on the results of these analyses, a revised classification is proposed. A key is provided to distinguish the tribes, and each is described with notes on distribution and evolutionary relationships, a list of the included genera (current to Feb. 2007), and illustrations of key morphological characters.

This book was released on 2007 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cicadellinae includes approximately 340 genera and over 2,000 species distributed worldwide, with member commonly referred to as sharpshooters. Sharpshooters are specialists on xylem sap, one of the nutritionally poorest diets, along with related cicadas and spittlebugs. Statistical analyses using phylogenetic contrasts of hemipteran body sizes did not show a significant increase in xylem feeding lineages, but results should be viewed cautiously. Sharpshooters host two mutualistic bacterial endosymbionts to complement their poor diet. Phylogenetic analyses were conducted based on the 16SrDNA from Baumannia and Sulcia and on COI, COII, 16SrDNA, and H3 for 29 leafhopper hosts. A congruent evolutionary history of both Baumannia and Sulcia with their sharpshooter hosts is supported based on all (Baumannia) or most (Sulcia ) statistical tests conducted here, suggesting a long-term association of these bacteria with their hosts. Additionally in this thesis, studies on the taxonomy of economically important genus Homalodisca are presented. Finally, incongruence in the higher-level classification of Cicadellinae is mainly due to the lack of robust phylogenetic hypotheses, like the one presented in this thesis. A morphological study based on 183 characters coded for 170 taxa and a molecular study based on partial regions of COI, COII, 16S rDNA, and H3 gene sequences from 91 taxa. Results support changes in the higher-level classification of Cicadellinae including: the erection of the tribe Oncometopiini based on previous members of the Proconiini; the treatment of Phereurhinini within the subfamily Cicadellinae; and placements of 9 genera in different tribes. Furthermore, based on a combined analysis, the origin of the egg-powdering behavior and related sexually-dimorphic morphological characteristics were studied. Results suggest a single origin of the egg-powdering behavior, possibly in the ancestor of Phereurhinini and Oncometopiini. Modifications of the female hindlegs for scraping the brochosomes off onto the egg nests were also acquired once in the ancestor of the Oncometopiini, while modifications on the female forewing setation for better anchoring of brochosome pellets, seem to have been acquired multiple times. Multiple losses of the behavior and its related associated traits occurred in various oncometopiine lineages.

Available in PDF, EPUB and Kindle. Book excerpt: This book will give an overview of insect ovaries, showing the diversities and the common traits in egg growth processes. The idea to write this book developed while looking at the flood of information which appeared in the early 1980s on early pattern formation in Drosophila embryos. At this time a significant breakthrough was made in studies of this little fly, combining molecular biological methods with classical and molecular genetics. The answers to questions about early pattern formation raised new questions about the architecture of ovaries and the growth of eggs within these ovaries. However, by concentrating only on Drosophila it is not possible to form an adequate picture of what is going on in insect ovaries, since the enormous diversity found among insects is not considered sufficiently. Almost forgotten, but the first to study the architecture of ovaries, was Alexander Brandt writing in 1878 in aber das Ei und seine Bildungsstaette (On the egg and its organ of development). More than 100 years later, a series of ten books or more would be required to survey all the serious informa tion we have today on insect oogenesis. Thus, this book is a personal selection and personal view on the theme, and the authors must be excused by all those scientists whose papers could not be included. The book briefly describes the ectodemes, i. e.

This book was released on 2022-08-11 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mesozoic Biological Events and Ecosystems in East Asia covers a wide range of topics, encompassing palaeoenvironments, palaeoecosystems and important vertebrate, invertebrate and plant fossils, some found in amber with excellent preservation of delicate morphological features. Fifty-three authors from a number of different disciplines – geochronology, palaeontology, stratigraphy, sedimentology, tectonics and geochemistry – contribute to the 18 articles in the volume. Well-preserved fossils and rocks continue to be found from marine and terrestrial sediments across East Asia. Over some years, the palaeontological and geological evidence discovered from this region has significantly improved our understanding of Mesozoic environments. In discussing feathered dinosaurs, primitive birds, early mammals, diverse insects, amber inclusions, the oldest-known flowers and research utilizing new, advanced methods, this volume explores Earth’s history in even greater detail. What other exciting discoveries are waiting to be unveiled in the future?
