Rayleigh-Wave Multipathing along the West Coast of North America
We have created a movie of surface ground motion for the 3 November 2002 Denali fault earthquake based on spectral-element simulations using crustal model CRUST2.0, mantle model S20RTS, topography and bathymetry model ETOPO5, and a finite-fault slip model. The movie features two anomalous wave packets that travel along the west coast of the North American plate following offgreat-circle paths. ...
متن کاملEffects of chronic exposure to thiamethoxam on larvae of the hoverfly Eristalis tenax (Diptera, Syrphidae)
There is widespread concern over the use of neonicotinoid pesticides in the agro-ecosystem, due in part to their high water solubility which can lead to widespread contamination of non-target areas including standing surface water. Most studies investigating the negative fitness consequences of neonicotinoids have focused on bees, with little research on the impact on other non-target insects. ...
متن کاملThe behaviour of hoverfly larvae (Diptera, Syrphidae) lessens the effects of floral subsidy in agricultural landscapes
20 Modern agricultural landscapes favour crop pests: herbivores benefit from resource 21 concentration and/or the absence of natural enemies in large areas of intensively farmed fields 22 interspersed by small fragments of natural or non-crop habitats. 23 Conservation biological control (CBC) aims at increasing the functional diversity of 24 agricultural landscapes to make them more hospitable ...
متن کاملRearing and observation of immature stages of the hoverfly Microdon katsurai (Diptera, Syrphidae)
BACKGROUND The hoverfly Microdon (Chymophila) katsurai Maruyama et Hironaga 2004 was speculated to be a myrmecophilous species associated with the ant Polyrhachis lamellidens based on observations of adults near the ant nest. However, there have been no reports regarding the observation of immature stages of this species in association with P. lamellidens. NEW INFORMATION For the first time, ...
متن کاملIncreasing background ozone during spring on the west coast of North America
[1] Using a 15-year record of O3 from Lassen Volcanic National Park, a rural elevated site in northernCalifornia, data from two aircraft campaigns conducted in 1984 and 2002 over the eastern North Pacific, and observations spanning 18 years from five U.S. west coast, marine boundary layer sites, we show that O3 in air arriving from the Eastern Pacific in spring has increased by approximately 10...
