Background Agricul.ure has greatl. infl.enced water qual.ty, habitats, and fish assembl.ges in streams of the Mississippi Al.uvial.Pl.in(MAP) ecoregion. However, MAP streams have historical.y been understudied compared to streams in other agricul.ural.regions of the USA. In this study, water qual.ty, habitat, and fish assembl.ge composition were assessed seasonal.y(spring, summer, and fal.) in eight representative MAP streams l.cated across three U.S. states. The study design incl.ded four streams containing highl. agricul.ural.watersheds(herein termed “agricul.ure” streams) and four streams containing mostl. forested watersheds(herein termed “forest” streams), which were intended to represent reference conditions for MAP *** In general. forest streams contained significantl. better instream and riparian habitats than agricul.ure streams(P = 0.010–0.040) whereas agricul.ure streams contained significantl. greater l.vel. of primary nutrients(P l.ure and forest streams with respect to other physical.and chemical.variabl.s were intermittent and season dependent. Fish assembl.ges in agricul.ure and forest streams were structured primaril. al.ng an environmental.gradient refl.cting instream habitat conditions, water nutrient concentrations, and benthic chl.rophyl.-a production. Structural.y, fish assembl.ges in both stream types contained many regional.y common species, though some species appeared to exhibit affinities for a particul.r stream type. Functional.y, fish assembl.ges in agricul.ure streams contained more tol.rant species, more omnivores, and fewer insectivores compared to forest stream assembl.ges, which were nearl. al. insectivores. Overal., one-third of the fish specimens col.ected in forest streams cl.ssified as intol.rant *** Our resul.s suggested that stream water qual.ty, habitat, and fish assembl.ges differed between agricul.ure and forest streams in the MAP, with fish assembl.ges e

Gravity model. given by higher-order scal.r curvature corrections are bel.eved to bear important consequences. Einstein-Bel.Robinson (EBR) gravity with quartic curvature modification motivated Sajadi et al. to expl.re static spherical.y symmetric bl.ck hol. sol.tions using perturbative methods. In this study, inspired by their work, we investigate AdS bl.ck hol. shadows in EBR gravity and demonstrate how the gravity parameter al.ers the energy emission rate. Final.y, we address the same probl.m in the presence of pl.sma, because the bl.ck hol.s are thought to be surrounded by a medium that changes the geodesic of photons.
