Abstract With climate change, streams and rivers are at increased risk of droughts flow intermittency. The full implications these conditions for fluvial carbon (C) processing stream-atmosphere CO 2 emissions not well understood. We performed a controlled drought experiment in outdoor hyporheic flumes. simulated small rain events that increase sediment moisture content, but do cause streamflow order to investigate how affect streambed dissolved organic C dynamics, biofilm respiration enzyme...
Abstract Aquatic habitats are particularly susceptible to chemical pollution, such as antimicrobials, from domestic, agricultural, and industrial sources. This has led the rapid increase of antimicrobial resistance (AMR) gene prevalence. Alternate approaches counteract pathogenic bacteria in development including synthetic biological surfactants sodium dodecyl sulfate (SDS) rhamnolipids. In aquatic environment, these may be present pollutants with potential affect biofilm formation AMR...
Surfactants are used to control microbial biofilms in industrial and medical settings. Their known toxicity on aquatic biota, their longevity the environment, has encouraged research biodegradable alternatives such as rhamnolipids. While previous investigated effects of biological surfactants single species biofilms, there remains a lack information regarding synthetic freshwater ecosystems. We conducted mesocosm experiment test how surfactant sodium dodecyl sulfate (SDS) rhamnolipid altered...
We examined the effects of a mixture contaminants found in agricultural watersheds on gut microbiota and physiology both freshwater mussel Lampsilis cardium, L. cardium host fish Micropterus salmoides.
Abstract Freshwater mussels provide invaluable ecological services but are threatened by habitat alteration, poor water quality, invasive species, climate change, and contaminants, including contaminants of emerging concern (CECs). Contaminants concerns well documented in aquatic environments, the Great Lakes Basin, limited information is available on how environmentally relevant mixtures affect freshwater mussel biology throughout their varied life stages. Our main goal was to assess...
Microbial biofilms have co-evolved with grazing animals, such as gastropods, to develop mutually beneficial relationships. Although microbial demonstrate resilience and resistance chemical exposure, pre-existing relationships can be negatively affected by input. In this study, we determined how the grazer, Littorina littorea (common periwinkle sea snail), a biological surfactant (rhamnolipid) interact on phototrophic marine biofilm. Biofilms were cultured in 32 twenty-liter buckets at...

Abstract Aquatic habitats are particularly susceptible to chemical pollution from domestic, agricultural, and industrial sources. Antimicrobials commonly used in medical environments reduce harmful bacteria biofilms. This has led the rapid increase prevalence of antimicrobial resistant (AMR) genes. Alternate remedies fight pathogenic biofilms development including synthetic biological surfactants such as sodium dodecyl sulphate (SDS) rhamnolipids respectively. In aquatic environment these...
