A bioassay-guided approach was used to identify defense compounds that are present on
the surface of Zostera marina and which inhibit settlement of microfoulers at natural …

We used photosynthetic activity (measured as chlorophyll a fluorescence) and
photosynthetic pigment concentrations to assess the effect of pulsed exposures of aged …

A study was conducted to determine the effect of the herbicide 2, 4-dichlorophenoxyacetic
acid (2, 4-D) on nine submersed macrophyte species. The first objective of the study was to …

A 1‐ha plot with smooth cordgrass (Spartina alterniflora) at three locations in Willapa Bay, a
southwestern Washington estuary, was aerially treated with 4.7 L/ha Rodeo® and 0.9 L/ha X …

Pulse amplitude modulation (PAM) fluorometry is ideally suited to measure the sub-lethal
impacts of photosystem II (PSII)-inhibiting herbicides on microalgae, but key relationships …

Purple loosestrife (Lythrum salicaria) is an invasive wetland perennial that became
established in northeastern North America in the early 1800s. Despite its designation as a …

The effect of the triazine herbicide, atrazine, on the photosynthetic O 2 evolution of 3 distinct
geographical races of Cyclotella meneghiniana Kütz, was investigated. Cells from Arizona …

Eelgrass (Zostera marina) leaf necrosis resulting from intertidal aerial exposure is described.
A desiccation index was developed and tested to quantitatively assess damage across …

The effects of algal concentration (Selanastrum capricornatum) on the toxicity of the
organochlorine pesticide endosulfan and the synthetic pyrethroid esfenvalerate to Daphnia …

The co-occurrence of aquatic contaminants, such as antibiotics and herbicides, has
motivated investigations into their interactive effects on aquatic organisms. We examined the …
