Sensor networks are revolutionizing environmental monitoring by producing massive quantities of data that are being made publically available in near real time. These data streams pose a challenge for ecologists because traditional approaches to quality assurance and quality control are no longer practical when confronted with the size of these...
Climate change is increasing the severity of pest and pathogen infestations affecting forests. Resulting shifts in disturbance patterns can have substantial ecological, social, and economic impacts on forested ecosystems and their dependent communities. Researchers are actively investigating methods to improve tree resistance to specific pests and pathogens and enhance forest...
A variational integral method in the Fourier transform domain is
used to calculate the characteristic normal mode parameters of a coupled
pair of nonsymmetrical microstrip transmission lines in an inhomogenous
dielectric medium under quasi-TEM conditions. These together with the
theory of such structures are used to show that ideal directional...
Analyses of long-term records at 35 headwater basins in the United States and Canada indicate that climate change effects on streamflow are not as clear as might be expected, perhaps because of ecosystem processes and human influences. Evapotranspiration was higher than was predicted by temperature in water-surplus ecosystems and lower...
