Conservation of fishes in altered ecosystems: the movement ecology of listed Grass Pickerel in an agricultural drain
Scientists and managers are pressed to conserve biodiversity in landscapes altered by human activities, especially agricultural changes in land cover, which can affect biodiversity dramatically. I tested whether Grass Pickerel Esox americanus vermiculatus in Beaver Creek, an agricultural drain near...
