Benthic Macroinvertebrate/ Water Quality
The Ecology contribution to address this question is to determine possible physicochemical impacts on 1) pond water quality and biological integrity, and 2) avulsed pit pond water quality and biological integrity in the historical pit location and receiving waters. These questions will be addressed by all study partners together in a more comprehensive fashion after the interim phase of reporting.

متن کاملEvaluation of Three Bottom Grab Samplers for Collecting River Benthos
The performances of the standard Petersen, Ekman, and Ponar grabs were compared using 2 sets of samples collected from gravel, sand, silt, and mud substrates. The data obtained during this study show that estimates of macroinvertebrate populations may vary considerably depending on the grab utilized, the nature of the substrate, and the number of replicate samples collected. The Ekman sampler w...

متن کاملAirborne virus sampling: Efficiencies of samplers and their detection limits for infectious bursal disease virus (IBDV).
INTRODUCTION The airborne transmission of infectious diseases in livestock production is increasingly receiving research attention. Reliable techniques of air sampling are crucial to underpin the findings of such studies. This study evaluated the physical and biological efficiencies and detection limits of four samplers (Andersen 6-stage impactor, all-glass impinger "AGI-30", OMNI-3000 and MD8 ...
