Imagine a statistics book for bioassays written by a statistician. Next, imagine a statistics book for bioassays written for a layman. Bioassays with Arthropods, Third Edition offers the best of both worlds by translating the terse, precise language of the statistician into language used by the laboratory scientist. The book explains the statistical basis and analysis for each kind of quantal response bioassay in just the right amount of detail. The first two editions were a great reference for designing, conducting, and interpreting bioassays: this completely revised and updated third edition will also train the laboratory scientist to be an expert in estimation of dose response curves. New in the Third Edition: Introduces four new Windows and Apple-based computer programs (PoloJR, OptiDose, PoloMixture and PoloMulti) for the analyses of binary and multiple response analyses, respectively Replaces out-of-date GLIM examples with R program samples Includes a new chapter, Population Toxicology, and takes a systems approach to bioassays Expands the coverage of invasive species and quarantine statistics Building on the foundation set by the much-cited first two editions, the authors clearly delineate applications and ideas that are exceptionally challenging for those not already familiar with their use. They lead you through the methods with such ease and organization, that you suddenly find yourself readily able to apply concepts that you never thought you would understand.

Biological control of weeds has been practised for over 100 years and Australia has been a leader in this weed management technique. The classical example of control of prickly pears in Australia by the cactus moth Cactoblastis cactorum, which was imported from the Americas, helped to set the future for biocontrol of weeds in many countries. Since then there have been many projects using Classical Biological Control to manage numerous weed species, many of which have been successful. Importantly, there have been no serious negative non-target impacts – the technique, when practised as it is in Australia, is safe and environmentally friendly. Economic assessments have shown that biocontrol of weeds in Australia has provided exceedingly high benefit-to-cost ratios. This book reviews biological control of weeds in Australia to 2011, covering over 90 weed species and a multitude of biological control agents and potential agents. Each chapter has been written by practising biological control of weeds researchers and provides details of the weed, the history of its biological control, exploration for agents, potential agents studied and agents released and the outcomes of those releases. Many weeds were successfully controlled, some were not, many projects are still underway, some have just begun, however all are reported in detail in this book. Biological Control of Weeds in Australia will provide invaluable information for biological control researchers in Australia and elsewhere. Agents used in Australia could be of immense value to other countries that suffer from the same weeds as Australia. The studies reported here provide direction to future research and provide examples and knowledge for researchers and students.

Make a Home for Wildlife helps you see your property in new ways and is the resource you need to take the sometimes daunting steps to improve the quality of your land. According to U.S. Forest Service, 250 million acres of woods and forests in the U.S. are privately held by 10 million individuals/families. Whether you live on a quarter-acre lot in the suburbs, own a 20-acre woodland retreat, run a farm of 100 acres, or belong to an outdoor club with hundreds or thousands of acres, you can make changes to the land, improvements that will turn your property into a better home for wildlife. Habitat projects can be simple or complex, short-term or spanning decades. Cost can be minimal, a few hours of your time spent doing pleasant work in the outdoors, or can run into the hundreds or thousands of dollars. And there is funding to help landowners make wildlife habitat. Focusing on the eastern US, from Canada to Florida and west to the Great Plains, this book describes basic habitat types—forest, shrublands, grasslands, and wetlands—and highlights over 150 select native and introduced trees, shrubs, and plants and explains how they are used or not by wildlife. The book includes 100+ profiles of prominent and interesting species of insects, reptiles, amphibians, birds, and mammals with info on animals and their habitat needs. Large and small mammals, resident and migratory birds, and insects are covered. Fergus relates stories of landowners who have made habitat in different states and regions in different ways.
