Book excerpt: Excerpt from Revision of the North American Species of the Genus Juncus It was thought best to add a second table, giving the extremes of every month and every year in those seven years, as the extremes are of more practical importance for the boatmen, as well as the inhabitants of the banks, than the means. The table shows that from September to February the river has never been higher than 17 feet, from March to July never lower than 6 feet, and in April, May, and June never lower than 8 feet above low water mark. The lowest stage, zero, was observed on December 21, 1863, and the highest, feet, on July 27, 1844. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book excerpt: Excerpt from Revision of the North American Species of the Genus Lithocolletis Hubner To Dr. Edward Meyrick of Marlborough, England, to whose consideration the proposed division of the genus was submitted, I am indebted for the expression of his opinion on the establishment of the subgenera, ' and also for the comparison of several American species with closely related European ones. Through the kindness of Dr. Henry Skinner of the Academy of Natural Sciences of Philadelphia, and Prof. Samuel Henshaw of the Museum of Comparative Zoology at Cambridge, Mass, I was given every opportunity to examine and sketch the many valuable types of species of this genus. Dr. James Fletcher has sent me a number of Canadian species for examination, for which privilege I return thanks.

This book was released on 2017-12-22 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Revision of the North American, Species of Xanthium, Vol. 4 The monographic study of the genus Xanthium is involved. In difficulties not only as to bibliography but also as to Species concept. Thanks to the kind and hearty co-operation of various botanists, we have been able to settle very satisfactorily the numerous matters of bibliography. The species concept in Xanthium, however, must long remain a perplexing problem. In temperate regions, the plants do not mature their fruits sufficiently for exact determination until after frost comes and the majority of collecting botanists have ceased their field-work. This renders good material in herbaria scanty in quantity and inadequate in quality. Some of the Species are known to exhibit most striking variations in fruiting characters, variations that with many botanists would be taken to represent varieties or subspecies. In fact, several of the more pronounced of these forms have been made the basis of new species by certain authors, notably Greene X. Acutum, X. Afiine, X. Cahform'cum, X. Glandulifemm). In the present monograph the writers have endeavored to be neither hasty in the proposal of new Specific names nor radical in the reduction of old names to synonomy. The taxonomic treatment has been made to accord as strictly as possible with the Observed data. We have retained several of the less well known species (e. G., X. Acerosum, X. Cylindricum, X. Globosum, species that with some botanists might be reduced to varietal or subspecific rank), because 'we have felt that only after fur ther field Observations and breeding tests can satisfactory conclusions as to their true status be reached.

Download or read book A Handbook of Global Freshwater Invasive Species written by Robert A. Francis and published by Routledge. This book was released on 2012-03-12 with total page 918 pages. Available in PDF, EPUB and Kindle. Book excerpt: Invasive non-native species are a major threat to global biodiversity. Often introduced accidentally through international travel or trade, they invade and colonize new habitats, often with devastating consequences for the local flora and fauna. Their environmental impacts can range from damage to resource production (e.g. agriculture and forestry) and infrastructure (e.g. buildings, road and water supply), to human health. They consequently can have major economic impacts. It is a priority to prevent their introduction and spread, as well as to control them. Freshwater ecosystems are particularly at risk from invasions and are landscape corridors that facilitate the spread of invasives. This book reviews the current state of knowledge of the most notable global invasive freshwater species or groups, based on their severity of economic impact, geographic distribution outside of their native range, extent of research, and recognition of the ecological severity of the impact of the species by the IUCN. As well as some of the very well-known species, the book also covers some invasives that are emerging as serious threats. Examples covered include a range of aquatic and riparian plants, insects, molluscs, crustacea, fish, amphibians, reptiles and mammals, as well as some major pathogens of aquatic organisms. The book also includes overview chapters synthesizing the ecological impact of invasive species in fresh water and summarizing practical implications for the management of rivers and other freshwater habitats.
