Description of Work This spring (2014) we will measure Asian carp eDNA over time at a Missouri River site downstream of multiple spawning areas before and during spawning. We will measure the amount of Asian carp eDNA in water samples. The amount of eDNA will be related to the numbers of eggs and larvae counted in matched samples (water samples taken at the same time and place). The time since the eDNA was released by the carp will be estimated and these results will be related to the average age of AC eggs and larvae in matched samples. We will also test for substances which interfere with the eDNA measurement techniques and can lead to false negatives. We will also be validating markers developed by USGS and...

Description of Work Initial tests of a variety of chemical stimuli identified a strong response to the algal food attractant. Field testing of chemical stimulants based on algae will seek to identify potent mixtures based on persistence and duration of attraction. These studies will include consideration of component chemicals such as amino acids produced by algae that enhance the attractiveness of the stimulus, based on carp smell and taste senses. Means of providing a sustained release of the stimulant will be explored through tests of various media. Tests will be conducted to confirm the possibility that carp can be conditioned to feeding stations that can be used to facilitate their capture. Relevance & Impact...

This data release includes physical and chemical characteristics of field collected sediment and soil samples in Missouri representing potential sediment/soil that may enter the water column during construction related activities. Three samples were collected, including Spring River sediment, Osage River bank soil and Columbia crushed limestone. The impacts of increased suspended solid level due to the three samples on early-stage freshwater mussels were examined using three freshwater mussel species, including Fatmucket (Lampsilis siliquoidea), Arkansas Brokenray (Lampsilis reeveiana), and Washboard (Megalonaias nervosa). Specifically, toxicity endpoints including survival, biomass, and growth of juveniles were...

This dataset provides results for the following: (1) metals concentrations in soils surrounding breeding song bird nest sites; (2) metals concentrations in invertebrates (earthworm and grub composites) collected near nest sites; (3) metals concentrations and delta-aminolevulinic acid dehydratase (ALAD) activity in avian blood samples; and (4) metals concentrations, indicators of oxidative stress and DNA damage, and histopathology in liver and/or kidney tissues collected from breeding song birds.
