Since the arrival of Europeans about 500 years ago, an estimated 50,000 non-native species have been introduced to North America (including Hawaii). Non-native species figure prominently in our lives, often as ornamentals, sources of food or pests. Although many introduced species are beneficial, there is increasing awareness of the enormous economic costs associated with non-native pests. In contrast, the ecological impacts of non-native species have received much less public and scientific attention, despite the fact that invasion by exotic species ranks second to habitat destruction as...

Soil microorganisms play a major role in the degradation and recycling of organic material. Microbes are involved in the food web and strongly contribute to soil fertility. In the past, attention was mainly directed towards free-living or particle-bound microorganisms, while the role of intestinal microbes of soil animals has been neglected.

For the first time, "Intestinal Microorganisms of Termites and Other Invertebrates" focuses on the microbes in gut systems of soil animals. It starts with a profound overview of the biology of soil invertebrates. A major part deals with the gut...

This is the first book on molluscs as sources for pharmaceutical drugs. Marine molluscs are very promising candidates for a wide range of biotechnological applications. For example, they possess analgesic drugs more potent than morphine and very effective anticancer agents. International experts provide coverage of the most stimulating topics related to molluscs. This knowledge of their history and current studies opens the door to the future.

The fourth volume of the IPMD Series covers, in three Sections, emerging issues in the integrated management of main nematode parasites of fruit, tree and forest crops. The chapters provide basic data about the crops concerned, listing main nematode threats, in order to facilitate their detection and management. Special attention is given to the management strategies as experienced by farmers, nematologists and consultants, in different areas of the world, including exploitation of plant resistance sources and integrated or organic management.

The first Section covers key nematode...

The great diversity of ostracod applications in biology and palaeontology is clearly illustrated by eighteen papers from the 15th International Symposium on Ostracoda. Collectively, the contributions provide a comprehensive update of ongoing research and the latest findings in ostracod sciences. You ll learn how ostracods are used as model groups in a variety of research studies, ranging from evolutionary biology to climate change."

Although the ancestral home of chelicerates was the sea, the vast majority of modern species live on land. Most students of spiders and mites also restrict themselves to terrestrial habitats. However, a surprising number of mites (Arachnida: Acari) have returned to a watery existence. Approximately 7000 species from the Mesostigmata, Astigmata, Oribatida, and especially the Prostigmata, now live in marine and freshwater habitats. In Aquatic Mites, a dozen chapters explore the distribution, ecology, behavior, genetics, and evolution of the most diverse of these astonishing arachnids. The...

Insect Behavior is the second edition of the text that for thirty years served as the fundamental introduction to a field of study that has been growing enormously. Today, new technologies and understandings are allowing questions to be shaped and answered in ways that once could not have been envisioned. However, massive new information also can overwhelm and obscure the broader perspectives needed to put new discoveries into context. Thus, the times fairly demand that students and non-specialists seek a wider understanding of diverse proximate and ultimate forces that cause...

Hands-On Chemical Ecology: Simple Field and Laboratory Exercises, a premiere collection of practical exercises in chemical ecology, offers tools and strategies for understanding this young science. The exercises included use general principles and follow a simple structure. Topics examined include birds, fish, insects, mammals, and plant chemistry among others. Additionally, exercises require accessible materials, ensuring that each can be easily modified and completed anywhere in the world with locally existing instruments. This text will be of value to undergraduate and graduates...

The offered volume intends to review the biological control theme of phytonematodes from several prospects: ecological; applicative as well as commercial state of the art; understanding the mode-of-action of various biocontrol systems; interaction between the plant host, nematodes surface and microorganism s; candidates for biocontrol; extrapolation of the wide knowledge existed in another systems for understanding biocontrol processes: C. elegans as a model and lessons from other natural systems; and exploiting advanced genomic tools to promote understanding biocontrol processes...

Do real stem cells and stem cell lineages exist in lower organisms? Can stem cells from one organism parasitize the soma and/or the germ line of conspecifics? Can differentiated cells in marine organisms be re-programmed to regenerate tissues, organs and appendages through novel de-differentiation, transdifferentiation, or re-differentiation processes, leading to virtually all three germ layers, including the germline? The positive answers to above questions open a new avenue in stem cell research: the biology of stem cells in marine organisms. It is therefore unfortunate that while the...

Fisheries genetics researchers will find invaluable the thirty-eight peer-reviewed contributions in this book, presented at the 20th Lowell Wakefield Fisheries Symposium "Genetics of Subpolar Fish and Invertebrates," held in May 2002 in Juneau, Alaska.

Looming over concerns of lost fisheries stocks and persistent erosion of genetic variability are predictions of global warming, which may further tax genetic resources. One consequence is an increased reliance on genetic applications to many aspects of fisheries management, aquaculture, and conservation.

The contributions in...
