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 Paths of Pollen written by Stephen Humphrey and published by McGill-Queen's Press - MQUP. This book was released on 2023-10-15 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: A tiny organism called pollen pulls off one of nature’s key tasks: plant reproduction. Pollination involves a complex network of different species interacting with one another and mutually adapting to their ecosystems, which are constantly changing. Some pollen grains require just a puff of wind to set them in motion, but most plants depend on creatures gifted with mobility. These might be birds, bats, reptiles, or insects including butterflies, beetles, flies, wasps, and over twenty thousand species of bee. In Paths of Pollen Stephen Humphrey asks readers to imagine a tipping point where plants and pollinators can no longer adapt to stressors such as urbanization, modern agriculture, and global climate change. Illuminating the science of pollination ecology through evocative encounters with biologists, conservationists, and beekeepers, Humphrey illustrates the significance of pollination to such diverse concerns as food supply, biodiversity, rising global temperatures, and the resilience of landscapes. As human actions erase habitats and raise the planet’s temperature, plant diversity is dropping and a growing list of pollinators faces decline or even extinction. Paths of Pollen chronicles pollen’s vital mission to spread plant genes, from the prehistoric past to the present, while looking towards an ecologically uncertain future.

Download or read book The Routledge Handbook of Urban Ecology written by Ian Douglas and published by Routledge. This book was released on 2020-12-15 with total page 1382 pages. Available in PDF, EPUB and Kindle. Book excerpt: This second edition covers recent developments around the world with contributors from 33 different countries. It widens the handbook’s scope by including ecological design; consideration of cultural dimensions of the use and conservation of urban nature; the roles of government and civil society; and the continuing issues of equity and fairness in access to urban greenspaces. New features include an emphasis on the biophilic design of homes and workplaces, demonstrating the value of nature, in order to counter the still prevalent attitude among many developers that nature is a constraint rather than a value. The volume explores great practical achievements that have occurred since the first edition, with many governments increasingly recognizing and legislating on urban nature and green infrastructure matters, since cities play a major role in adapting to change, particularly to climate crisis. New topics such as the ecological role of light at night and human microbiota in the urban ecosystem are introduced. Additional attention is given to food production in cities, particularly the multiple roles of urban agriculture and household gardens in different contexts from wealthy communities to the poorest informal settlements in deprived communities. The emphasis is on demonstrating what can be achieved, and what is already being done. The book aims to help scholars and graduate students by providing an invaluable and up-to-date guide to current urban ecological thinking across the range of disciplines, such as geography, ecology, environmental science/studies, planning, and urban studies, that converge in the study of towns and cities and urban design and living. It will also assist practitioners and civil society members in discovering the ways diff erent specialists and thinkers approach urban nature.

Book excerpt: This publication is the result of a course on identification of Hymenoptera given three times since 1985 at the Centre for Land and Biological Resources Research. The considerable interest in these courses indicated the need for a comprehensive identification guide to all extant families of Hymenoptera. The main emphasis is on family identification using the keys, which are complemented by family sketches. The sketches include a taxonomic diagnosis to supplement the keys, a summary of the biology, the size and distribution, and important literature references.

Download or read book The Routledge Handbook of Urban Ecology written by Ian Douglas and published by Routledge. This book was released on 2010-12-21 with total page 1163 pages. Available in PDF, EPUB and Kindle. Book excerpt: The birds, animals, insects, trees and plants encountered by the majority of the world’s people are those that survive in, adapt to, or are introduced to, urban areas. Some of these organisms give great pleasure; others invade, colonise and occupy neglected and hidden areas such as derelict land and sewers. Urban areas have a high biodiversity and nature within cities provides many ecosystem services including cooling the urban area, reducing urban flood risk, filtering pollutants, supplying food, and providing accessible recreation. Yet, protecting urban nature faces competition from other urban land uses. The Handbook of Urban Ecology analyses this biodiversity and complexity and provides the science to guide policy and management to make cities more attractive, more enjoyable, and better for our own health and that of the planet. This Handbook contains 50 interdisciplinary contributions from leading academics and practitioners from across the world to provide an in-depth coverage of the main elements of practical urban ecology. It is divided into six parts, dealing with the philosophies, concepts and history of urban ecology; followed by consideration of the biophysical character of the urban environment and the diverse habitats found within it. It then examines human relationships with urban nature, the health, economic and environmental benefits of urban ecology before discussing the methods used in urban ecology and ways of putting the science into practice. The Handbook offers a state-of the art guide to the science, practice and value of urban ecology. The engaging contributions provide students and practitioners with the wealth of interdisciplinary information needed to manage the biota and green landscapes in urban areas.
