Ecological Responses at Mount St. Helens: Revisited 35 years after the 1980 Eruption ISBN: 9781493974498
The 1980 eruption of Mount St. Helens created an outstanding opportunity to investigate mammal community assembly during primary succession. From 1983 through 2015, we documented the arrival of 34 of the 45 mammals in the regional species pool and th

We documented the recruitment, loss, and turnover of 51 species of ground beetles during 30 years of post-eruption primary succession on the Pumice Plain near Spirit Lake at Mount St. Helens. We observed high species turnover, with many species colon

Mycorrhizae are symbiotic mutualisms between plants and fungi, in which carbon is exchanged for nutrients. The eruption of Mount St. Helens was a large event that covered a topographically complex land area with disturbances of varying intensity that

Sap-feeding and predaceous arthropod faunas of forage bunchgrasses in reseeded rangeland vegetation were examined. Four major species of sap feeders were found; the major predators were spiders. Grass monoculture had very high densities of sap feeder

The degree to which microhabitat elements such as shade from shrubs are used by lizards and the relative importance of such factors compared to others (e.g., prey availability) remains poorly understood. We examined habitat associations of Desert Hor

Habitat structure is of great importance for the distribution and abundance of various organisms. Spiders are especially sensitive to structural features of their environment. Although spiders are influenced by habitat structure, it remains unclear w

Vertebrate carrion decomposition and nutrient cycling have both direct and indirect effects on the soil properties, fauna, and flora associated with an animal's carcass. While few comprehensive quantitative studies have been undertaken, those that ha

A suite of factors including prey availability and prey defenses influence prey selection by consumers and ultimately define an animal’s feeding strategy (e.g., generalist or specialist). Here we examined the relationship between availability and s

Livestock grazing is one of the most common forms of land use in the western United States, yet scientists struggle to accurately predict grazing impacts. This study examined the initial response of desert horned lizards (Phrynosoma platyrhinos) to c
