Book Description

"Wallace, together with Darwin was the founder of modern evolutionary theory, and when Darwin received Wallace's paper of 1858 (a year before the publication of the Origin of Species), he wrote to Lyell "All my originality, whatever it may amount to, will be smashed"."I never saw a more striking coincidence.Your words (referring to Lyell's earlier warnings that Darwin might be anticipated) have come true with a vengeance." In 1858 Wallace was already preparing an announcement of an importent zoogeographical discovery, which proposed a boundary line dividing the archipelago of Indo-Malayan and Australian zoological regions. The culmination of Wallace's approach was achieved in his monumental two-volume "The geographical Distribution." and it is a pioneer-work in zoogeography."--Abebooks website.

Book Description

Conservation and biodiversity of protists The conservation of biodiversity is not just an issue of plants and vertebrates. It is the scarcely visible invertebrates and myriads of other microscopic organisms that are crucial to the maintenance of ecological processes on which all larger organisms and the composition of the atmosphere ultimately depend. Biodiversity and Conservation endeavours to take an holistic view of biodiversity, and when the opportunity arises to issue collections of papers dealing with too-often neglected groups of organisms. The protists, essentially eukaryotes that cannot be classi?ed in the kingdoms of animals, fungi, or plants, include some of the lea- known groups of organisms on earth. They are generally treated as a separate kingdom, commonly named Protista (or Protoctista) in textbooks, but in reality they are a mixture of organisms with disparate a?nities. Some authors have hypothesized that the numbers of protists are not especially large, and that many have extraordinarily wide distributions. However, the p- ture that unfolds from the latest studies discussed in this issue is di?erent. There are many species with wide ranges, and proportionately more cosmopolitan species than in macroorganism groups, as a result of their long evolutionary histories, but there are also de?nite patterns and geographical restrictions to be found. Further, some protists are linked to host organisms as mutualists or parasites and necessarily con?ned to the distributions of their hosts.

Book Description

Wallace's Island Life is one of the foundation works of zoogeography. It focused on the detailed problems of animal dispersal and speciation. Like Darwin, Wallace classified islands as either oceanic (no previous connection to a land mass) or continental (previously connected to a land mass). He considered the means by which each class of island might become colonized, the types of animals most likely to perform the necessary migrations, and the conditions-such as major climactic or geologic change-under which the migrations might have been made. Wallace was the first to use the new knowledge of Pleistocene ice ages to explain certain phenomena of animal distribution, and in Island Life he speculated about the possible causes of glaciation. He was one of the few 19th-century scientists to realize that astronomical causes alone would not suffice, but had to be combined with a corresponding elevation in the northern land mass -- Abe books website.

Book Description

Pearly mussels (Unionoidea) live in lakes, rivers, and streams around the world. These bivalves play important roles in freshwater ecosystems and were once both culturally and economically valuable as sources of food, pearls, and mother-of-pearl. Today, however, hundreds of species of these mussels are extinct or endangered. David L. Strayer provides a critical synthesis of the factors that control the distribution and abundance of pearly mussels. Using empirical analyses and models, he assesses the effects of dispersal, habitat quality, availability of fish hosts, adequate food, predators, and parasites. He also addresses conservation issues that apply to other inhabitants of fresh waters around the globe and other pressing issues in contemporary ecology.

Book Description

Climate change poses many challenges that affect society and the natural world. With these challenges, however, come opportunities to respond. By taking steps to adapt to and mitigate climate change, the risks to society and the impacts of continued climate change can be lessened. The National Climate Assessment, coordinated by the U.S. Global Change Research Program, is a mandated report intended to inform response decisions. Required to be developed every four years, these reports provide the most comprehensive and up-to-date evaluation of climate change impacts available for the United States, making them a unique and important climate change document. The draft Fourth National Climate Assessment (NCA4) report reviewed here addresses a wide range of topics of high importance to the United States and society more broadly, extending from human health and community well-being, to the built environment, to businesses and economies, to ecosystems and natural resources. This report evaluates the draft NCA4 to determine if it meets the requirements of the federal mandate, whether it provides accurate information grounded in the scientific literature, and whether it effectively communicates climate science, impacts, and responses for general audiences including the public, decision makers, and other stakeholders.
