Download or read book An Annotated Catalogue of Elachistinae of the World Lepidoptera Gelechioidea Elachistidae written by Lauri Kaila and published by . This book was released on 2019 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Abstract: An annotated catalogue of world species of Elachistinae (Lepidoptera: Gelechioidea: Elachistidae) is presented. The classification follows recent phylogenetic studies. Genera and the species within each genus are listed in alphabetical order. All family, genus and species-group names of Elachistinae published before 28 August 2018 are treated. Sixty-six genus-group names are listed, 60 of which are nomenclaturally available. In the classification followed in this catalogue the species are placed in 10 genera. There are 1016 nomenclaturally available and 106 unavailable species-group names. Of these, 805 names are currently considered to represent valid species. For each species the following data are given: the reference to the original publication and the page; type locality; deposition of the name-bearing types; in the genus Elachista, the taxonomic rank with the subgenus and the informal species group when applicable; distribution; larval host plants; references to essential illustrations, and remarks, when needed. Synonyms are listed under valid names; distribution with geographic area and country records, for Australia, Canada and U.S.A. territories, provinces and states are given; Russia is divided into subregions. Larval host plant records are listed with notes regarding uncertain records. When possible, original references that are considered trustworthy in later literature are given, as well as relevant literature references for illustrations for each species. Synonymies, incorrect subsequent spellings and misspellings are listed under each species with full reference. Alphabetical lists are given for subfamily and infra-generic groupings of species of the genus Elachista, to summarize the placement of each species in its subgenus and species group within the subgenera. 110 valid and one unavailable species-group names originally described to genera currently considered elachistines, but later removed, are listed. When known, their current identity is given. The following taxonomic changes are made: Elachista amseli (Parenti, 1981), a secondary junior homonym of E. amseli Rebel, 1933, is replaced with E. parentii nom. nov.; Hemiprosopa asiatica Sinev, 1998 = Elachista asiatica (Sinev, 1998) stat. nov., comb. nov.; E. bipunctella (Sinev & Sruoga, 1995), a junior secondary homonym of E. bipunctella Treitschke, 1833, is replaced as E. ochropunctosa Kaila, nom. nov.; Elachista cerusella f. juncta Dufrane, 1957 is raised as species-rank name Elachista juncta Dufrane, 1957 stat. nov., a synonym of E. maculicerusella Bruand; Svenssonia corsicana Tautel & Nel, 2010 is transferred to Elachista (Aphelosetia), comb. n.; E. cupreella Blanchard, 1852 is transferred to Perittia, comb. nov.; E. flammeaepennella Costa, 1836 is raised as valid species, stat. rev.; Illantis Meyrick, 1921 is considered a junior subjective synonym of Elachista, syn. nov.; I. picroleuca Meyrick, 1921 is transferred to Elachista, comb. nov.; E. kosteri Traugott-Olsen, 1995 = E. differens Parenti, 1978, syn. nov.; E. oritropha Bradley, 1965 = E. iriphaea (Meyrick, 1932), syn. nov.; Paraperittia Rebel, 1916 = Phaulernis Meyrick, 1895 (Epermeniidae) syn. nov.; P. uniformella Rebel, 1916 = Phaulernis dentella (Zeller, 1839), syn. nov.; and E. zernyi Hartig, 1941 = E. stelviella Amsel, 1932, syn. nov. A lectotype is designated for Paraperittia uniformella Rebel. Elachista macquartella Duponchel, 1840 is considered a nomen oblitum, stat. nov. Keywords: Lepidoptera, Gelechioidea, Elachistidae"--Page 3.
Download or read book High Mountain Conservation in a Changing World written by Jordi Catalan and published by Springer. This book was released on 2017-08-03 with total page 413 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides case studies and general views of the main processes involved in the ecosystem shifts occurring in the high mountains and analyses the implications for nature conservation. Case studies from the Pyrenees are preponderant, with a comprehensive set of mountain ranges surrounded by highly populated lowland areas also being considered. The introductory and closing chapters will summarise the main challenges that nature conservation may face in mountain areas under the environmental shifting conditions. Further chapters put forward approaches from environmental geography, functional ecology, biogeography, and paleoenvironmental reconstructions. Organisms from microbes to large carnivores, and ecosystems from lakes to forest will be considered. This interdisciplinary book will appeal to researchers in mountain ecosystems, students and nature professionals. This book is open access under a CC BY license.

Download or read book Inselbergs written by S. Porembski and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 543 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inselbergs are isolated rock outcrops that stand out abruptly from surrounding plains. Despite the widespread occurrence of granite inselbergs throughout all climatic and vegetational zones, their remarkably rich plant life was largely neglected in the recent literature. This richly and partly in color illustrated volume provides a detailed survey of all major abiotic and biotic features characteristic for inselbergs. The extreme environmental conditions on inselbergs are described in depth as well as specific adaptive traits of rock outcrop plants including their morphological, anatomical and physiological responses. The diversity and structure of inselberg plant communities are examined on a global scale with detailed regional accounts for different tropical and temperate zones.
Download or read book Plant Geography of Chile written by Andres Moreira-Munoz and published by Springer Science & Business Media. This book was released on 2011-01-19 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first and so far only Plant Geography of Chile was written about 100 years ago, since when many things have changed: plants have been renamed and reclassified; taxonomy and systematics have experienced deep changes as have biology, geography, and biogeography. The time is therefore ripe for a new look at Chile’s plants and their distribution. Focusing on three key issues – botany/systematics, geography and biogeographical analysis – this book presents a thoroughly updated synthesis both of Chilean plant geography and of the different approaches to studying it. Because of its range – from the neotropics to the temperate sub-Antarctic – Chile’s flora provides a critical insight into evolutionary patterns, particularly in relation to the distribution along the latitudinal profiles and the global geographical relationships of the country’s genera. The consequences of these relations for the evolution of the Chilean Flora are discussed. This book will provide a valuable resource for both graduate students and researchers in botany, plant taxonomy and systematics, biogeography, evolutionary biology and plant conservation.
Download or read book Relict Species written by Jan Christian Habel and published by Springer Science & Business Media. This book was released on 2009-12-03 with total page 451 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mankind has evolved both genetically and culturally to become a most successful and dominant species. But we are now so numerous and our technology is so p- erful that we are having major effects on the planet, its environment, and the b- sphere. For some years prophets have warned of the possible detrimental consequences of our activities, such as pollution, deforestation, and overfishing, and recently it has become clear that we are even changing the atmosphere (e. g. ozone, carbon dioxide). This is worrying since the planet’s life systems are involved and dependent on its functioning. Current climate change – global w arming – is one recognised consequence of this larger problem. To face this major challenge, we will need the research and advice of many disciplines – Physics, Chemistry, Earth Sciences, Biology, and Sociology – and particularly the commitment of wise politicians such as US Senator Al Gore. An important aspect of this global problem that has been researched for several decades is the loss of species and the impoverishment of our ecosystems, and hence their ability to sustain themselves, and more particularly us! Through evolutionary time new species have been generated and some have gone extinct. Such extinction and regeneration are moulded by changes in the earth’s crust, atmosphere, and resultant climate. Some extinctions have been massive, particularly those asso- ated with catastrophic meteoric impacts like the end of the Cretaceous Period 65Mya.

This book was released on 1998 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report profiles the natural history of the rich hardwood forests of the middle St. John River Valley in New Brunswick and in the eastern section of Aroostook County, Maine. Section 1 defines what is meant by the St. John River Valley Hardwood Forest (SJRHF), describes the forest assemblage type in general, and outlines how that type differs from hardwood forest assemblages found in other regions of the Maritime Provinces. Section 2 describes the physical characteristics of the central St. John valley and the vegetation history of the area, from the beginning of the post-glacial period to the present. Section 3 profiles the life history characteristics of ground flora associated with temperate deciduous forest. Section 5 gives detailed descriptions of the rare vascular plant species associated with the SJRHF. The final section reviews conservation prospects for the SJRHF in New Brunswick based on current land use trends and makes management recommendations for its protection.
