Phosphorus export across an urban to rural gradient in the Chesapeake Bay watershed
[1] Watershed export of phosphorus (P) from anthropogenic sources has contributed to eutrophication in freshwater and coastal ecosystems. We explore impacts of watershed urbanization on the magnitude and export flow distribution of P along an urban-rural gradient in eight watersheds monitored as part of the Baltimore Ecosystem Study Long-Term Ecological Research site. Exports of soluble reactiv...
متن کاملI – Recent Fish Health Issues in the Chesapeake Bay Watershed
A northern snakehead Channa argus population was documented within a 23km reach of the tidal freshwater Potomac River and associated tributaries in 2004 when 20 snakeheads were collected with several gears including hook-and-line and electrofishing. An additional 271 snakeheads were collected in 2005 primarily with various electrofishing gears. Boat electrofishing mean catch rate increased from...
متن کاملAddressing Variable Phosphorus Solubility of Organic Amendments Inthe Chesapeake Bay Program’s Phase 6 Watershed Model
Because land-applied organic amendments (manures and biosolids) have widely differing susceptibilities to phosphorus (P) solubilization by water, total P (TP) content is an unreliable indicator of their potential to impact water quality. While P can be transported by erosion of Penriched soil particles, much research has addressed P loss to surface runoff and subsurface drainage in the form of ...
متن کاملRevised Method and Outcomes for Estimating Soil Phosphorus Losses from Agricultural Land in the Chesapeake Bay Watershed Model.
Current restoration efforts for the Chesapeake Bay watershed mandate a timeline for reducing the load of nutrients and sediment into receiving waters. The Chesapeake Bay watershed model (WSM) has been used for two decades to simulate hydrology and nutrient and sediment transport; however, spatial limitations of the WSM preclude edge-of-field scale representation of phosphorus (P) losses. Rather...
متن کاملthe effect of oxytetracycline on serum calcium, phosphorus and magnesium in cattle
نتایج این مطالعه نشان می دهد که مقدار کلسیم (یونیزه و تام)، منیزیم و فسفر به طور معنی داری تغییر پیدا کرد به جزء مقدار کلسیم تام و منیزیم در روش داخل عضلانی که تغییر معنی داری نداشته است. بر اساس نتایج این مطالعه می توان نتیجه گیری کرد که اکسی تتراساکلین بر روی مقادیر سرمی کلسیم و منیزیم تأثیر می گذارد باید مقدار این کاتیون ها در بیماران، در هنگامی که اکسی تتراسایکلین استفاده می شود مورد توجه ق...
