Trivers and Willard proposed that female mammals should adjust their investment in male versus female offspring relative to the effect of their underlying body condition on their ability to produce high quality offspring. I conducted studies testing whether litter size-sex ratio tradeoffs predicted by adaptive sex allocation (ASA) theory occur among Richardson's ground squirrel (Urocitellus richardsonii) dams, and whether circulating plasma glucose levels of those dams influence offspring sex ratio as predicted by Cameron's glucose metabolism hypothesis. The results of these studies validate the use of the Roche Diagnostics Accu-chek® Aviva glucometer in measuring Richardson's ground squirrel plasma glucose concentration, inform future studies attempting to test the glucose metabolism hypothesis, and provide evidence from long-term data of litter size-sex ratio tradeoffs supporting earlier reports of ASA among Richardson's ground squirrels from the same study population that have been called into question owing to small sample sizes derived over single breeding seasons.

Since its original publication in 1960, The Wildlife Techniques Manual has remained the cornerstone text for the professional wildlife biologist. Now fully revised and updated, this seventh edition promises to be the most comprehensive resource on wildlife biology, conservation, and management for years to come. Superbly edited by Nova J. Silvy, the thirty-seven authoritative chapters included in this work provide a full synthesis of methods used in the field and laboratory. Chapter authors, all leading wildlife professionals, explain and critique traditional and new methodologies and offer thorough discussions of a wide range of relevant topics, including: • experimental design • wildlife health and disease • capture techniques • population estimation • telemetry • vegetation analysis • conservation genetics • wildlife damage management • urban wildlife management • habitat conservation planning A standard text in a variety of courses, the Techniques Manual, as it is commonly called, covers every aspect of modern wildlife management and provides practical information for applying the hundreds of methods described in its pages. To effectively incorporate the explosion of new information in the wildlife profession, this latest edition is logically organized into a two-volume set: Volume 1 is devoted to research techniques and Volume 2 focuses on management methodologies. The Wildlife Techniques Manual is a resource that professionals and students in wildlife biology, conservation, and management simply cannot do without. Published in association with The Wildlife Society
