After the disaster: The hydrogeomorphic, ecological, and biological responses to the 1980 eruption of Mount St. Helens, Washington
(Geological Society of America, 2009)The 1980 eruption of Mount St. Helens caused instantaneous landscape disturbance on a grand scale. On 18 May 1980, an ensemble of volcanic processes, including a debris avalanche, a directed pyroclastic density current, ... -
Early primary succession on Mount St. Helens: impact of insect herbivores on colonizing lupines
(Ecology, 2002)Lupinus lepidus var. lobbii, the earliest plant colonist of primary successional habitats at Mount St. Helens, can dramatically influence successional rates and ecosystem development through N fixation and other facilitative ... -
The Effect of Consumers and Mutualists of Vaccinium membranaceum at Mount St. Helens: Dependence on Successional Context
(PLoS One, 2011)In contrast to secondary succession, studies of terrestrial primary succession largely ignore the role of biotic interactions, other than plant facilitation and competition, despite the expectation that simplified interaction ... -
Evaluating approaches to the conservation of rare and endangered plants
(Ecological Society of America, 1994)Nearly 25% of the estimated 250,000 species of vascular plants in the world may become extinct within the next 50 yr (Raven 1987), and 22% of vascular plant species in the United States are currently of conservation concern ... -
N-P Co-Limitation of Primary Production and Response of Arthropods to N and P in Early Primary Succession on Mount St. Helens Volcano
(PLoS One, 2010)The effect of low nutrient availability on plant-consumer interactions during early succession is poorly understood. The low productivity and complexity of primary successional communities are expected to limit diversity ... -
Predation on the Invasive Copepod, Pseudodiaptomus forbesi, and Native Zooplankton in the Lower Columbia River: An Experimental Approach to Quantify Differences in Prey-Specific Feeding Rates
(PLoS One, 2015)Invasive planktonic crustaceans have become a prominent feature of aquatic communities worldwide, yet their effects on food webs are not well known. The Asian calanoid copepod, Pseudodiaptomus forbesi, introduced to the ... -
A Stoichiometric Model of Early Plant Primary Succession
(American Naturalist, 2011)The relative importance of plant facilitation and competition during primary succession depends on the development of ecosystem nutrient pools, yet the interaction of these processes remains poorly understood. To explore ... -
Successional Change in Phosphorus Stoichiometry Explains the Inverse Relationship between Herbivory and Lupin Density on Mount St. Helens
(PLoS One, 2009)The average nitrogen-to-phosphorus ratio (N?P) of insect herbivores is less than that of leaves, suggesting that P may mediate plant-insect interactions more often than appreciated. We investigated whether succession-related ... -
Trophic interactions during primary succession: Herbivores slow the reinvasion of lupines on Mount St. Helens
(American Naturalist, 2000)Lupines (Lupinus lepidus var. lobbii), the earliest plant colonists of primary successional habitats at Mount St. Helens, were expected to strongly affect successional trajectories through facilitative effects. However, ... -
Variation in flowering phenology and its consequences for lupines colonizing Mount St. Helens
(Ecology, 1998)Species colonizing large-scale disturbances face heterogeneous environmental conditions that may strongly affect the relationship between phenotypic variation and reproduction. We investigated spatiotemporal variation in ... -
When can herbivores reverse the spread of an invading plant? A test case from Mount St. Helens
(American Naturalist, 2005)Here we study the spatial dynamics of a coinvading consumerresource pair. We present a theoretical treatment with extensive empirical data from a longstudied field system in which native herbivorous insects attack a ...
