Artificial reefs create less productive fish communities than their natural counterparts mostly due to differences in habitat complexity and food potential. Are there other factors contributing to this decrease in productivity, such as the material of the habitat? I tested the response of the tidepool sculpin, Oligocottus maculatus, to man-made...

Magnetotelluric (MT) data from two sites 150 and
300 km southeast of San Francisco, California (geomagnetic
dipole latitude: 43 degrees, L approximately 1.9) show that
the usual MT assumption of spatially uniform external magnetic
fields is violated to a significant degree in the period
range 10-30 s. Inter-station transfer functions...

Optimum timing and use of fungicides for disease control are improved by an understanding of the characteristics of fungicide physical mode of action. Greenhouse and field experiments were conducted to quantify and model the duration of pre- and postinfection activity of fungicides most commonly used for control of hop downy...

Analytical methods capable of trace measurement of semi-volatile organic
compounds (SOCs) are necessary to assess the exposure of tadpoles to contaminants as a
result of long-range and regional atmospheric transport and deposition. The following
study compares the results of two analytical methods, one using pressurized liquid
extraction (PLE) and the...
