Over the years, I’ve had a lot of people ask me why I stayed in the Philadelphia region - why didn’t I just move to a bigger city or a remote island beach, or live a nomadic lifestyle? Aside from my emotional attachments to this place, my response was (and still is) that I feel so spoiled to live here, because no matter what meal I eat in various corners of the planet, chances are, I can find it in Philly. Behavior is a highly sensitive endpoint that influences overall organism fitness and can be used to detect toxicity of environmentally relevant concentrations of aquatic pollutants.Royal Sushi & Izakaya / Photograph by Jesse ItoĪs a food and travel writer, I’ve researched culinary traditions across four continents, from following spice trade routes through Israel and Europe to fishing with the Māori in New Zealand. Early life exposures in fish to pyrethroids cause toxicity at environmentally relevant concentrations, which can alter behavior. The influence that salinity has on organism physiology and the partitioning of hydrophobic chemicals, such as pyrethroids, has driven interest in how toxicity changes in saltwater compared to freshwater. Pyrethroids, a class of commonly used insecticides, are frequently detected in aquatic environments, including estuaries.

Pyrethroids Across A Salinity Gradient, Sara J. While previous investigations have significantly improved our knowledge of shale reservoirs, it has also highlighted …Ĭomparative Behavioral Ecotoxicology Of Inland Silverside Larvae Exposed To Preexisting cemented fractures in unconventional shale reservoirs are abundant and preferentially reactivate during induced hydraulic fracturing treatment to create necessary large-scale permeability. Permeability at multiple scales from nanometer-scale pore sizes and nano-darcy permeability to completion-induced fractures defining a 100’s of meter stimulated reservoir volume plays a significant role in hydrocarbon flow during production in shale reservoirs. Optimizing recovery from unconventional shale reservoirs has generated considerable research into optimal recovery methods through hydraulic fracturing design and shale reservoir characterization in the development of long-term hydrocarbon producers.
