Book Description
Howard Evans was a brilliant ethologist and systematist, describing over 900 species in over a dozen entomology and natural history books. Upon his death in 2002, he left behind an unfinished manuscript, intended as an update of his classic 1966 work, The Comparative Ethology and Evolution of the Sand Wasps. O'Neill, Evans's former student and coauthor, has completed and enlarged this work into a tribe-by-tribe, species-by-species review of Bembicinae studies from the last four decades.

Book Description
Social behavior occurs in some of the smallest animals as well as some the largest, and the transition from solitary life to sociality is an unsolved evolutionary mystery. In The Evolution of Social Wasps, James H. Hunt examines social behavior in a single lineage of insects, wasps of the family Vespidae. He presents empirical knowledge of social wasps from two approaches, one that focuses on phylogeny and life history and one that focuses on individual ontogeny, colony development, and population dynamics. He also provides an extensive summary of the existing literature while demonstrating how it can be clouded by theory. Hunt's fresh approach to the conflicting literature on sociality highlights how oft repeated models can become fixed in the thinking of the scientific community. Instead, Hunt presents a mechanistic scenario for the evolution of sociality in wasps that changes our perspective on kin selection, the paradigm that has dominated thinking about social evolution since the 1970s. This innovative new model integrates life history, nutrition, fitness and ecology in which social insect biologists will find a rich storehouse of ideas and information, and behavioral ecologists will find a bracing challenge to long accepted models. Engagingly written, bold, and provocative, The Evolution of Social Wasps marks a milestone in our understanding of one of lifes major evolutionary transitions - the origin of social behavior.

Book Description
Differences in reproductive strategies are often hypothesized as the adaptive result of frequency-dependent and condition-dependent selection. However, conventional explanations of mating systems based on ecology do not include the fitness effects of interactions between the sexes. Ecological factors, phenotypic variation, and intersexual interactions must all be examined in order to understand the evolution of reproductive behavior. I investigated the natural history, ecology, and behavior of the sand wasp Steniolia nigripes (Hymenoptera: Crabronidae), using both field observations and controlled behavioral trials. The sand wasps (Bembicinae) are a large, highly diverse group of wasps with extensive variation in male and female reproductive behavior across species. Steniolia nigripes shows reversed sexual size dimorphism and a previously undescribed resource-based territorial strategy in males. The results of this research indicate that the distribution of S. nigripes is determined primarily by the availability of prey used to provision offspring. Seasonal changes and social environment also affect the distribution and behavior of both male and female wasps. A small minority of male wasps hold territories consisting of plants that females visit for prey and nectar. These territorial males are significantly larger and more aggressive than other males, indicating that body size may be important to male competitive success. However, there is no clear evidence of female mating preferences based on either the size or the behavior of males, despite the frequent harassment of females by territorial males in the field. This species thus demonstrates unusual and highly variable morphological and behavioral phenotypes. Studying unique species such as Steniolia nigripes provides a rich opportunity for a comparative understanding of the evolution of body size and reproductive tactics.

Book Description
A comprehensive study of the biology, taxonomy, and ecology of each of the soil biotic groups. The first chapter presents an ecological approach to soil studies. The remaining 42 chapters provide specific information on each of the taxonomic groupings. Contains illustrated identification keys to each group. Some keys go by functional morphological delineations; others lead the reader to classical identification at family, genus, or species levels. Some incorporate descriptions of new genera and species. Especially useful for the study of mesic, xeric, and hydric terrestrial sites. Includes an extensive bibliography.
