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 ...
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, ...
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 ...
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, ...
Early primary succession on Mount St. Helens: impact of insect herbivores on colonizing lupines
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 ...
