When characterizing the processes that shape ecosystems, ecologists increasingly use the unique perspective
offered by repeat observations of remotely sensed imagery. However, the concept of change embodied in much of
the traditional remote-sensing literature was primarily limited to capturing large or extreme changes occurring
in natural systems, omitting many more...

Bi-weekly sampling of zooplankton and environmental parameters was conducted along a cross-shelf transect off the coast of Newport, OR, USA (44.65°N) from 1996 to present. Results have demonstrated the feasibility of using copepod community structure as an early indicator of ecosystem response to seasonal and large scale environmental changes in...
The interannual and intraseasonal variability of the North American monsoon is of great interest because a large proportion of the annual precipitation for Arizona and New Mexico arrives during the summer monsoon. Forty-one years of daily monsoon season precipitation data for Arizona and New Mexico were studied using wavelet analysis....
We describe a new algorithm for robust principal component analysis (PCA) of electromagnetic (EM) array data, extending previously developed multivariate methods to include arrays with large data gaps, and only partial overlap between site occupations. Our approach is based on a criss-cross regression scheme in which polarization parameters and spatial...
The Bering Sea ecosystem has experienced significant climatic and biological shifts
over the past 3 decades, including temporal and spatial fluctuations of jellyfish biomass. Jellyfish
are important predators and competitors of fish; thus, it is critical to understand the effects of environmental
factors on their population dynamics. We explored the...

The history of forest change processes is written into forest age and distribution and affects earth systems at many scales. No one data set has been able to capture the full forest disturbance and land use record through time, so in this study, we combined multiple lines of evidence to...
