Invertebrates constitute the majority of animal species and are critical for ecosystem functioning and services. Nonetheless, global invertebrate biodiversity patterns and their congruences with vertebrates remain largely unknown. We resolve the first high-resolution (~20-km) global diversity map for a major invertebrate clade, ants, using biodiver...

Eighteen new collection records from four new locations in California are reported for the very rare ant Temnothorax paiute. It had previously been collected only twice in the 1950s from two locations.

Keys to the species of ants in the deserts of California.

Dichotomous keys to the 96 species of ants that are known to occur in the San Gabriel Mountains of Southern California are provided. The keys are designed to be supplemented by the imaged found at AntWeb.org.

An analysis of the creationists' program as it is encountered in schools and the public arena. Specific examples of creationist claims are accompanied by technically competent explanations of the science and suggested teaching strategies.

1. Although numerous studies have examined the ecology of plant resistance to herbivores and the distribution of herbivores within plant hybrid zones, few have examined how plant hybridization influences herbivore growth, development, or life history. The experiment reported here examines variation in survivorship, development time, and final adult...

Hummingbirds may need to replace electrolytes and minerals lost during daily diuresis and seasonal reproduction. Minerals such as calcium may not be obtained in sufficient quantities from a nectar-rich diet alone. We report observations of female Rufous Hummingbirds (Selasporus rufus) ingesting soil in western Oregon and review other known observat...
