This book was released on 2020 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Abstract: Anchylorhynchus Schoenherr is a genus of palm-associated weevils currently including 22 described species in the Neotropics. These weevils engage in brood pollination interactions with species in at least four genera of palms (Arecaceae), representing an emerging system for the study of mutualisms. Here we revise the taxonomy of Anchylorhynchus and propose the first phylogenetic hypothesis for the group, based on morphology. Anchylorhynchus chrysomeloides sp. nov., Anchylorhynchus goiano sp. nov., Anchylorhynchus imitator sp. nov., Anchylorhynchus latipes sp. nov., Anchylorhynchus multisquamis sp. nov. and Anchylorhynchus rectus sp. nov. are described, Anchylorhynchus gottsbergerorum Vanin is a new junior subjective synonym of Anchylorhynchus bicarinatus O'Brien, and Anchylorhynchus eriospathae Bondar and Anchylorhynchus pictipennis Hustache are new junior subjective synonyms of Anchylorhynchus tremolerasi Hustache, resulting in 25 valid species for the genus. We provide genus and species descriptions with a new dichotomous key to the species and updated information on geography and host associations based on museum records and extensive new collections. We also produce a new morphological matrix with 113 characters, 11 of them based on measurements while accounting for allometry, correlation and power to delimit groups. The software pipeline to produce these characters was encoded in a graphical user interface named DiscretzR, made available here. Analysis of this matrix under parsimony and Bayesian inference resulted in strong support for the monophyly of Anchylorhynchus, but weaker support for most clades within the genus. Reconstruction of the host plant associations indicates that the common ancestor of Anchylorhynchus visited flowers of Syagrus Mart., with later transitions to other genera restricted to one of the major clades of Anchylorhynchus. This taxonomic revision with the first phylogeny for the group provides a foundation for future evolutionary studies in the genus.

Download or read book Morphology of Baridinae and Related Groups Coleoptera Curculionidae written by Steven R. Davis and published by PenSoft Publishers LTD. This book was released on 2009-05-20 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the first comprehensive review of baridine morphology to date and attempts to present this morphological diversity in a comparative framework by including comparisons of other weevil subfamilies thought to be more closely related. Although this is by no means an exhaustive treatment, it is in hope that this study provides a better understanding of the evolution of this large radiation and the similarities and differences that comprise this group and outline its boundaries. By including over 1000 figures, it was a desire to cover as much of the morphological variation within Baridinae as possible, however, much remains that is not included here. This treatment is being presented in advance of a cladistic analysis of the subfamily based on morphology, thus much of this review pertains to describing structures worthy of inclusion in phylogenetic studies.
Download or read book Biology Immature Stages and Systematics of Snail killing Flies of the Genus Colobaea Diptera Sciomyzidae with Overviews of Aspects of the Tribe Sciomyzini written by author 1 and published by . This book was released on 2020 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Abstract: All reared larvae of flies of the genus Colobaea Zetterstedt, 1837 (Diptera: Sciomyzidae), which comprises 15 valid species, kill and consume freshwater nonoperculate pulmonate snails. New data are presented on the geographic distribution, biology, morphology of immature stages, and classification of Colobaea. Life cycle information is provided from field data and laboratory rearings for four of the 11 Palearctic species--C. bifasciella (Fallén), C. deemingi Knutson & Bratt n.sp., C. pectoralis (Zetterstedt), and C. punctata (Lundbeck)--and for one of the three Nearctic species, C. americana Steyskal. Colobaea bifasciella is shown to be one of the most highly specialized parasitoid Sciomyzini, laying eggs on shells of Galba truncatula (O.F. Müller) and Stagnicola palustris (O.F. Müller) in temporary, intermittent, or vernal semiterrestrial situations. Each larva feeds in only one host snail, which is not killed until shortly before the larva completes development. Puparia are strongly modified to fit tightly within the shell of the host. The other reared species are shown to be less specialized than C. bifasciella, with eggs being laid upon vegetation, the larvae behaving as parasitoids-predators-saprophages of exposed aquatic snails, and the puparia of all four species being adapted to a lesser degree than C. bifasciella to fitting within the shell of the host snail. In nature, C. americana attacks Gyraulus parvus (Say) and Physa Draparnaud sp.; C. pectoralis attacks Anisus vortex (L.) and Bathyomphalus contortus (L.); and C. punctata attacks Gyraulus albus O.F. Müller, Lymnaea "peregra," Planorbarius corneus (L.), and Planorbis planorbis (L.). In the laboratory, these species also attacked and consumed other freshwater nonoperculate snails; C. deemingi was reared on Gyraulus intermixtus (Mousson) and Radix gedrosiana (Say), and an adult fly of the Palearctic C. distincta (Meigen) emerged from a puparium found in the shell of Anisus spirorbis (L.) collected in nature. Described and figured are eggs, larvae of all three instars, and puparia of the five laboratory-reared species. To provide perspective on features of Colobaea, diagnostic features are summarized of the immature stages of the Sciomyzini and the suprageneric categories of Sciomyzidae. The biogeography of the tribe Sciomyzini is presented, along with details of known geographical distribution. The classification and phylogenetic position of Colobaea are discussed. Included are a checklist of all known taxa of Colobaea, maps of geographic distribution, and a key to adults of the 15 valid species.

Download or read book Biology As Ideology written by Richard Lewontin and published by House of Anansi. This book was released on 1996-10-23 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: R. C. Lewontin is a prominent scientist -- a geneticist who teaches at Harvard -- yet he believes that we have placed science on a pedestal, treating it as an objective body of knowledge that transcends all other ways of knowing and all other endeavours. Lewontin writes in this collection of essays, which began their life as CBC Radio's Massey Lectures Series for 1990: "Scientists do not begin life as scientists, after all, but as social beings immersed in a family, a state, a productive structure, and they view nature through a lens that has been molded by their social experience... . Science, like the Church before it, is a supremely social institution, reflecting and reinforcing the dominant values and vices of society at each historical epoch." In Biology as Ideology Lewontin examines the false paths down which modern scientific ideology has led us. By admitting science's limitations, he helps us rediscover the richness of nature -- and appreciate the real value of science.

Download or read book A Guide to the Beetles of Australia written by George Hangay and published by CSIRO PUBLISHING. This book was released on 2010-04-27 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: A Guide to the Beetles of Australia provides a comprehensive introduction to the Coleoptera – a huge and diverse group of insects. Beetles make up 40 per cent of all insects known to science. The number of described beetle species in the world – around 350 000 – is more than six times the number of all vertebrate species. New beetle species are being discovered all the time. Of the 30 000 species that may occur in Australia, only 20 000 have been scientifically described. These include around 6500 weevils (Curculionidae), 2600 scarabs, dung beetles and chafers (Scarabaeidae); and 2250 leaf beetles (Chrysomelidae). A Guide to the Beetles of Australia highlights the enormous diversity of this unique insect Order. It emphasises the environmental role of beetles, their relationships with other plants and animals, and their importance to humans. Winner of the 2010 Whitley Medal.

Download or read book A Survey of the Weevils of Ukraine written by Tatyana Nikulina and published by . This book was released on 2015 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our knowledge of Ukrainian bark and ambrosia beetles (Coleoptera: Curculionidae: Scolytinae and Platypodinae) is summarized as a baseline for future studies of the fauna, with a checklist including information on distribution, host trees, biology and taxonomy. One hundred twenty-two species are recorded from Ukraine, of which seven are recorded for the first time. One species is recorded for the first time from Europe. Previous records of 24 species are considered dubious and requiring confirmation. In contrast to the Palaearctic Catalogue (Knížek 2011b), we consider Anisandrus maiche to be first described by Kurentsov (1941) rather than by Eggers (1942); A. maiche (Eggers, 1942) is a junior synonym of A. maiche(Kurentsov, 1941).

Download or read book A catalogue of Lithuanian beetles Insecta Coleoptera written by Vytautas Tamutis and published by PenSoft Publishers LTD. This book was released on 2011-08-05 with total page 500 pages. Available in PDF, EPUB and Kindle. Book excerpt: A catalogue of Lithuanian beetles (Insecta, Coleoptera)? is the first most comprehensive publication on Lithuanian beetle fauna. This volume provides a general overview of the main features of Lithuanian territory, the origins and formation of the beetle fauna and their conservation measures, the faunistic investigations in Lithuania to date revealing the most important stages of the research process. Basing on the published and interactive sources since 1830 the full lists of recorded and expected for Lithuania beetle species as well as enlarged list of references have been compiled in the catalogue. After revision of public beetle collections in Lithuania, the authors propose to remove 43 species from the beetle species list of the country on the grounds they have been wrongly identified or published by mistake. The information published in the monograph will serve to further research Lithuanian beetles.
