Book Description
"Abstract: We present a revision of the Clavatulidae gastropods of the Neogene of the Central and Eastern Paratethys seas. In total, 111 species level names have been used in the literature for Clavatulidae of the Paratethys Sea. After revision, we document 83 species. Seventeen genus-level groups are recognized, of which eleven are formally described. Six species-groups cannot be clearly placed in a certain Clavatulidae genus. The presence of Clavatula, Perrona, Pusionella, Scaevatula and Tomellana in the Paratethyan assemblages documents a biogeographic relationship with extant Clavatulidae faunas from the tropical eastern Atlantic. No Indo-West Pacific influences were observed, as Paratethyan species previously placed in Turricula, which belongs within the Clavatulidae, do not belong within that genus. The Langhian (middle Miocene) diversity of 62 species is comparable to the number of extant species recorded from West Africa (~65 species), but displays a much higher diversity at genus level. This high biodiversity in Paratethyan assemblages suggests that the Central Paratethys was a major center of radiation for clavatulid gastropods, which is also expressed by a high endemicity of 98.8%. In contrast, the clavatulid diversity in the Eastern Paratethys was very low and stratigraphically restricted to the early Miocene Sakaraulian. Granulatocincta nov. gen., Megaclavatula nov. gen., Neoperrona nov. gen., Olegia nov. gen., Striopusionella nov. gen. are established as new genera. Clavatula sorini nov. sp., 'Clavatula' irisae nov. sp., Tomellana dulaii nov. sp., Tomellana aueri nov. sp., Granulatocincta callim nov. sp., Granulatocincta theoderichi nov. sp., Megaclavatula grunerti nov. sp., Megaclavatula pilleri nov. sp., Neoperrona zoltanorum nov. sp., Olegia mandici nov. sp., Perrona koeberli nov. sp., Perrona loetschi nov. sp., Pusionella hofmanni nov. sp. are described as new species from the Miocene Paratethys, and 'Clavatula' ariejansseni nov. sp., 'Clavatula' atatuerki nov. sp. and Granulatocincta pelliscrocodili nov. sp., are described from the eastern Proto-Mediterranean Karaman Basin of Turkey. 'Clavatula' jarzynkae nov. nom., Perrona grossi nov. nom., Perrona ilonae nov. nom. and Perrona wanzenboecki nov. nom. are introduced as new names for Clavatula auingeri Finlay, 1927 [non Hilber, 1879], Pleurotoma (Clavatula) auingeri Hilber, 1879 [non Hoernes, 1875], Clavatula vindobonensis nodosa Csepreghy-Meznerics, 1954 [non Bellardi, 1847] and Pleurotoma concinna Handmann, 1883 [non Scacchi, 1836] respectively. Clavatula kowalewskii Bałuk, 2003, Clavatula letkésensis Csepreghy-Meznerics, 1953, Pleurotoma aculeatum Eichwald, 1830, Pleurotoma subscalaris Handmann, 1882 and Pleurotoma (Clavatula) reginae Hoernes & Auinger, 1891 are treated as junior subjective synonyms of Pleurotoma (Clavatula) antoniae Hoernes & Auinger, 1891, Perrona emmae (Hoernes & Auinger, 1879), Pleurotoma laevigata Eichwald, 1830, Pleurotoma schreibersi Hörnes, 1854 and Pleurotoma (Clavatula) apolloniae Hoernes & Auinger, 1891 respectively. Keywords: Miocene, Paratethys Sea, Proto-Mediterranean Sea, Clavatulidae, biodiversity, Europe"--Page 5.

Book Description
From the rain forests of Borneo to the tenements of Manhattan, winged insects are a conspicuous and abundant feature of life on earth. Here, Robert Dudley presents the first comprehensive explanation of how insects fly. The author relates the biomechanics of flight to insect ecology and evolution in a major new work of synthesis. The book begins with an overview of insect flight biomechanics. Dudley explains insect morphology, wing motions, aerodynamics, flight energetics, and flight metabolism within a modern phylogenetic setting. Drawing on biomechanical principles, he describes and evaluates flight behavior and the limits to flight performance. The author then takes the next step by developing evolutionary explanations of insect flight. He analyzes the origins of flight in insects, the roles of natural and sexual selection in determining how insects fly, and the relationship between flight and insect size, pollination, predation, dispersal, and migration. Dudley ranges widely--from basic aerodynamics to muscle physiology and swarming behavior--but his focus is the explanation of functional design from evolutionary and ecological perspectives. The importance of flight in the lives of insects has long been recognized but never systematically evaluated. This book addresses that shortcoming. Robert Dudley provides an introduction to insect flight that will be welcomed by students and researchers in biomechanics, entomology, evolution, ecology, and behavior.

Book Description
This project was designed to build a documented chronostratigraphic and outcrop record of depositional sequences calibrated across European basins. Data on standard stages, magnetostratigraphy, and geochronology integrated with high resolution biostratigraphy calibrate the stratigraphic position of depositional sequence boundaries. Higher order eustatic sequences show a significant increase in the number identified. A good portion of the European Mesozoic and Cenozoic succession is set in the sequence stratigraphic context with a stratigraphic record of its bonding surfaces.
