The effects of various environmental factors on the success of tristylous Lythrum salicaria.
(2001)
Invasive species can influence a community, causing a decline or even extinction of native species. Lythrum salicaria, or purple loosestrife, is an exotic, tristylous plant that spreads over disturbed wetland areas in ...
Investigation of ozone stomatal flux in a northern mixed hardwood forest during the 1999 to 2004 growing seasons
(2007)
Hourly ozone stomatal fluxes (Fs_O3) were calculated for the University of Michigan’s Biological Station (UMBS) forest in northern Michigan from June 15 to September 15 for each year from 1999 to 2004 based on a set of ...
Measurement of temperature, fuel concentration and equivalence ratio fields using tracer LIF in IC engine combustion
(Springer-Verlag, 2000-11)
A technique based on planar laser-induced fluorescence of 3-pentanone, for measurements of absolute concentration, temperature and fuel/air equivalence ratios in turbulent, high-pressure combustion systems such as an ...
Integrative measures of consumption rates in salmon: expansion and application of a trace element approach
(Blackwell Science Ltd, 2004-10)
1. Establishing reliable estimates of consumption is necessary for understanding the physiology, bioenergetics and trophic relationships of organisms. For fish, the inability to measure consumption directly prevents a ...
Parametric and Semiparametric Model-Based Estimates of the Finite Population Mean for Two-Stage Cluster Samples with Item Nonresponse
(Blackwell Publishing Inc, 2007-12)
This article concerns item nonresponse adjustment for two-stage cluster samples. Specifically, we focus on two types of nonignorable nonresponse: nonresponse depending on covariates and underlying cluster characteristics, ...
Nitrogen flow and distribution in a northern Michigan dune system
(2008)
While the study of nutrient flow from terrestrial habitats to aquatic habitats is well known, little is known of the nutrient flow from aquatic to terrestrial habitats. The study of nitrogen flow from water to land in a ...
Climate‐related variations in mixing dynamics in an Alaskan arctic lake

Shallow bias in Neogene palaeomagnetic directions from the Guide Basin, NE Tibet, caused by inclination error
(Blackwell Science Ltd, 2005-12)
Too-shallow inclinations have frequently been observed in Cenozoic sedimentary strata in central Asia, and new palaeomagnetic results obtained by us from the Guide Basin in NE Tibet are no exception. We use a statistical ...
Impairment of feeding behavior of the spottail shiner (Notropis hudsonius) by metacercariae of the digenetic trematode Diplostomum flexicaudum.
(2004)
The spottail shiner (Notropis hudsonius) was infected in the laboratory with cercariae of the eye fluke Diplostomum flexicaudum to determine if infection by the parasite impaired feeding behavior of the fish. The mean and ...
