Nonindigenous aquatic species are becoming increasingly common in coastal and inland waters, largely due to the global transport of zooplankton via commercial shipping and recreational boating. The cost of mitigation and lost income due to invas[...]

Dams and river regulation greatly alter the downstream environment for gross primary production (GPP) because of changes in water clarity, flow, and temperature regimes. We estimated reach-scale GPP in five locations of the regulated Colorado Ri[...]

A sediment core has been sampled at a spatial resolution of about two centimeters for noble-gas analysis of the sediment pore water. This high-resolution sampling allowed an excess of dissolved atmospheric gases to be identified in the pore wate[...]

To test the hypothesis that the sex ratio of the copepod Acartia tonsa is biased at birth, adult sex ratios of the offspring of families (21 families in 2011 and 72 in 2013) produced by field-caught females were determined in the laboratory unde[...]
