Background Agriculture has greatly influenced water quality, habitats, and fish assemblages in streams of the Mississippi Alluvial Plain(MAP) ecoregion. However, MAP streams have historically been understudied compared to streams in other agricultural regions of the USA. In this study, water quality, habitat, and fish assemblage composition were assessed seasonally(spring, summer, and fall) in eight representative MAP streams located across three U.S. states. The study design included four streams containing highly agricultural watersheds(herein termed “agriculture” streams) and four streams containing mostly forested watersheds(herein termed “forest” streams), which were intended to represent reference conditions for MAP *** In general, forest streams contained significantly better instream and riparian habitats than agriculture streams(P = 0.010–0.040) whereas agriculture streams contained significantly greater levels of primary nutrients(P rences between agriculture and forest streams with respect to other physical and chemical variables were intermittent and season dependent. Fish assemblages in agriculture and forest streams were structured primarily along an environmental gradient reflecting instream habitat conditions, water nutrient concentrations, and benthic chlorophyll-a production. Structurally, fish assemblages in both stream types contained many regionally common species, though some species appeared to exhibit affinities for a particular stream type. Functionally, fish assemblages in agriculture streams contained more tolerant species, more omnivores, and fewer insectivores compared to forest stream assemblages, which were nearly all insectivores. Overall, one-third of the fish specimens collected in forest streams classified as intolerant *** Our results suggested that stream water quality, habitat, and fish assemblages differed between agriculture and forest streams in the MAP, with fish assemblages e

Ethical principles form a bedrock to medical practice in any specialty,guiding physicians to appropriate attitudes and behaviors.A formal ethics curriculum can be difficult to generate de novo in an ophthalmology training program.A number of barriers exist in most ophthalmology departments:trainees may think ethics is of secondary importance compared to core basic and clinical science topics;most ophthalmology faculty have no formal degree in medical ethics;there is limited didactic time with competing academic,clinical,and surgical priorities;work-hours regulations may limit the time available to deliver“para-professional”lectures;and there is a belief that the medical ethics lectures during medical school is a sufficient amount of coursework to last through a physician’s career with no need for continuing professional *** four pillars of medical ethics are beneficence,non-maleficence,autonomy,and *** addition,morals,ethics,and professionalism are important aspects of sound medical practice.A curriculum specific to medical ethics in ophthalmology can be developed in any of our sub-specialties and include lectures,curated readings,case rounds,and clinic wrap-up *** considerations are part of everyday clinical practice,and a structured ethics curriculum can be incorporated into ophthalmology training *** concept of backward design can be used to structure the curriculum,starting with the expected outcome,then designing authentic assessments,and finally putting together a learning plan that has students actively involved in ethical *** paper will provide a guide to developing an ethics curriculum for an ophthalmology training program utilizing the concept of backwards design and guide the reader through the process of developing expected learning outcomes,authentic assessments,and a unified learning plan.
