Author: A nomenclator of extant and fossil taxa of the Valvatidae (Gastropoda, Ectobranchia)
Author: Gerhard HaszprunarPublisher: PenSoft Publishers LTD
ISBN: 9546427152
Category :
Languages : en
Pages : 179
Book Description
The present catalog provides a compilation of all supra- and (infra-) specific taxa of extant and fossil Valvatidae (Ectobranchia), a group of freshwater operculate snails (Gastropoda, Heterobranchia). Taxa initially described in this family and bsequently classified in other families (in particular Hydrobiidae and Planorbidae, but among others also larval shells of trichopteran insects) as well as names due to errors or misspellings are likewise included. For each taxon the full original reference and the ype locality (and type horizon in fossils) is provided. Remarks on nomenclatorical problems and possible solutions are added if necessary. As a novelty the extensive reference list is as far as possible directly linked to the internet source (digital view or pdf-download) of the respective papers to facilitate future taxonomic research.
Zoogeography of Arachnida
Author: Petar BeronPublisher: Springer
ISBN: 3319744186
Category : Science
Languages : en
Pages : 995
Book Description
This volume merges all geographical and paleogeographical data on all groups of the arachnofauna. The book features topics such as the ecological factors, climate and other barriers that influence the distribution of arachnida. It also elaborates on the characteristics of the distribution such as arachnida at high altitude (e.g. Himalaya), in caves, in polar regions and highlights differences between the arachnofauna of e.g. Mediterranean regions vs Central Europe, West African vs Indomalayan and more. Furthermore, amongst other topics the volume also includes chapters on the systems of arachnida, fossil orders, dispersal and dispersion, endemics and relicts, regional arachnogeography, cave and high altitude arachnida.
The Common Hamster (Cricetus Cricetus)

ISBN:
Category : Nature
Languages : en

Book Description
The Common Hamster is a fascinating species that differs from other hibernating small mammals in several aspects. Females have up to three litters per season and under favourable conditions both males and females are sexually mature in their first year. The ability to cache food changes the need for fattening prior to hibernation and consequently can alter the pattern of reproductive activity. The Common Hamster has lived in agricultural areas in close association with humans for centuries. During the last few decades, the loss of suitable habitats and modern agriculture technology have brought the species close to extinction in many areas. It has thus been listed as a highly threatened species in several European countries. Preventative measures require detailed knowledge about the biology of the species and a "hamster-friendly" management scheme in agricultural areas. In this volume, contributions made at the 13th Meeting of the International Hamster Workgroup have been summarized. Studies investigating burrow architecture, population dynamics, predation pressure, life span and reproductive activity underline the environmental flexibility of the species. The results of conservation programs are presented and discussed. Reports of breeding regimes with selected light-dark-cycles that can be used to optimize reproductive output and may benefit reintroduction projects have also been included. Generally the presented results should help broaden our knowledge about the Common Hamster and promote international networks to plan, implement, coordinate and evaluate management programs.

Book Description
"Bibliographic references to works pertaining to the taxonomy of Coleoptera published between 1758 and 1900 in the non-periodical literature are listed. Each reference includes the full name of the author, the year or range of years of the publication, the title in full, the publisher and place of publication, the pagination with the number of plates, and the size of the work. This information is followed by the date of publication found in the work itself, the dates found from external sources, and the libraries consulted for the work. Overall, more than 990 works published by 622 primary authors are listed. For each of these authors, a biographic notice (if information was available) is given along with the references consulted"--[p. 1].
