Download or read book Revision and Reclassification of Lasioglossum Evylaeus L Hemihalictus and L Sphecodogastra in Eastern North America Hymenoptera written by Gibbs Jason and published by . This book was released on 2013 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: The black species of weak-veined Lasioglossum (or Hemihalictus series) in eastern North America are revised to clarify their taxonomy and nomenclature and to facilitate identification. A subgeneric classification based upon available phylogenetic data is applied. Lasioglossum (Sphecodogastra) is applied more broadly than any previous usage to include many species typically classified as L. (Evylaeus). The subgenus L. (Evylaeus) is retained but applied narrowly in agreement with phylogenetic results. Lasioglossum (Hemihalictus) has historically been considered monotypic but is here applied to many species of L. (Dialictus) sensu lato (equivalent to the carinaless L. (Evylaeus) of some authors). Usage of L. (Dialictus) is restricted primarily to species with metallic integument. Additional subgeneric synonymies for extralimital taxa are formalized and discussed. Descriptions are provided for each species with a synonymic list, diagnosis, and notes on taxonomy and biology. The recently revised Onagraceae-specialist species of L. (Sphecodogastra) are given abbreviated treatments. Notes on available DNA barcode data are given, with diagnostic characters supplied for closely related species. One new species is described: L. (Sphecodogastra) seillean Gibbs and Packer and the males of L. fedorense (Crawford) and L. pectinatum (Robertson) are described for the first time. The following three new synonymies are proposed: Lasioglossum (Hemihalictus) sopinci (Crawford), senior subjective synonym of Evylaeus bradleyi Mitchell; Lasioglossum (Hemihalictus) macoupinense (Robertson), senior subjective synonym of Halictus divergens Lovell; and Lasioglossum (Hemihalictus) inconditum (Cockerell), senior subjective synonym of Halictus tracyi Cockerell. Lasioglossum inconditum is here considered to be distinct from the Palaearctic species L. rufitarse (Zetterstedt). A lectotype is designated for Halictus quebecensis Crawford. We present the first record of L. lustrans (Cockerell) and L. swenki (Crawford) in Canada and the first record of L. lusorium (Cresson) east of the Mississippi River. Updated keys to species are provided for the fauna of eastern North America.

Download or read book World Bee Day 2022 Pollinators in Urban Environments written by Guaraci Duran Cordeiro and published by Frontiers Media SA. This book was released on 2024-01-26 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: World Bee Day takes place on the 20th of May, commemorating the date on which we acknowledge the influence of the most popular pollinator species, bees, in plant diversity and our society. The aim of this Research Topic is to raise awareness of the importance of pollinators in urban areas, the threats they face and their contribution to sustainable development. It is in this spirit that Frontiers is launching a new article collection to coincide with this UN day. This occasion not only offers an opportunity to acknowledge the sustainable approach that is protecting wildlife in any form in urban areas, but also to consider the importance of bees in our ecosystem and their positive impact on human society. This Frontiers in Sustainable Cities Research Topic aims to address Urban Greening and Resource Management-specific dimensions of this UN day, highlighting the importance of having healthy green areas and all-level decision-making and considering how pollinators interact with many levels of our society. Topics may include, but are by no means limited to: - Technology and practices for urban greening and pollinator populations - Urban solutions for declining bee populations - Influence of community gardens on pollinator populations - Increases of the awareness of the importance of pollinators in local community gardens and urban greening - Policy making to protect pollinators in urban areas - Facilitating urban management of natural resources for the benefit of pollinator populations - Harnessing SDGs for urban pollinators population - Citizen science to monitor pollinators - Pollination service in urban areas - Effects of environmental contaminants, climate warning and light on pollinators - Plant pollinator networks in cities and urban areas

Download or read book The Solitary Bees written by Bryan N. Danforth and published by Princeton University Press. This book was released on 2019-08-27 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: The most up-to-date and authoritative resource on the biology and evolution of solitary bees While social bees such as honey bees and bumble bees are familiar to most people, they comprise less than 10 percent of all bee species in the world. The vast majority of bees lead solitary lives, surviving without the help of a hive and using their own resources to fend off danger and protect their offspring. This book draws on new research to provide a comprehensive and authoritative overview of solitary bee biology, offering an unparalleled look at these remarkable insects. The Solitary Bees uses a modern phylogenetic framework to shed new light on the life histories and evolution of solitary bees. It explains the foraging behavior of solitary bees, their development, and competitive mating tactics. The book describes how they construct complex nests using an amazing variety of substrates and materials, and how solitary bees have co-opted beneficial mites, nematodes, and fungi to provide safe environments for their brood. It looks at how they have evolved intimate partnerships with flowering plants and examines their associations with predators, parasites, microbes, and other bees. This up-to-date synthesis of solitary bee biology is an essential resource for students and researchers, one that paves the way for future scholarship on the subject. Beautifully illustrated throughout, The Solitary Bees also documents the critical role solitary bees play as crop pollinators, and raises awareness of the dire threats they face, from habitat loss and climate change to pesticides, pathogens, parasites, and invasive species.

Download or read book Pollination Services to Agriculture written by Barbara Gemmill-Herren and published by Routledge. This book was released on 2016-04-14 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is only recently that the immense economic value of pollination to agriculture has been appreciated. At the same time, the alarming collapse in populations of bees and other pollinators has highlighted the urgency of addressing this issue. This book focuses on the specific measures and practices that the emerging science of pollination ecology is identifying to conserve and promote animal pollinators in agroecosystems. It reviews the expanding knowledge base on pollination services, providing evidence to document the status, trends and importance of pollinators to sustainable agricultural production. It provides practical and specific measures that land managers can undertake to ensure that agroecosystems are supportive and friendly to pollinators. It draws on the Global Pollination Project, supported by UNEP/GEF and implemented by FAO and seven partner countries (Brazil, Ghana, India, Kenya, Nepal, Pakistan and South Africa), which serve to provide "lessons from the field".

Download or read book Dorylaimida written by Mohammad Shamim Jairajpuri and published by BRILL. This book was released on 1992-01-01 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Dorylaimida represent a large and very important group of soil and freshwater inhabiting nematodes of great agricultural importance. Both in appearance and mode of life they represent a wide diversity and as a consequence the number of species and higher taxa that have been described hitherto is the highest within Nematoda. The identification of species, genera, families, etc. of Dorylaimida is very difficult and at times causes problems for the specialist too. The large number of species on the one hand and often the meagre descriptions on the other make even well-known taxonomists to look at Dorylaimida with great hesitation and desperation. M. Shamim Jairajpuri and Wasim Ahmad have undertaken a great task in summarizing, evaluating and systematizing all the knowledge that has been published so far.
