Pickeral rush (Pontederia cordata) occupies wetland shoreline. This emergent aquatic, with its leaves and flowers above water and portions of the stem under water, is found typically in shallow, quiet water. The seeds can be eaten like nuts and the young leaf-stalks cooked as greens. Deer also feed on these plants. The common name suggests that this plant, as well as the fish known as pickerel, occupy the same habitat. plant,marsh,wetland,native,bog,swamp,Maryland

Killdeer (Charadrius vociferus) nest in busy parking lot protect Found on golf courses or vacant gravell parking lots, this noisy plover is best known for its "broken wing" behavior. If a predator approaches, a nesting killdeer performs a conspicuous distraction display, dragging itself as if mortally wounded, often on one foot, its wings seemingly broken and its rusty tail fanned toward the intruder. This feigning of injury is effective in luring the predator away from the eggs or young, at which point the bird then "recovers" and flies off, calling loudly.

Storm Timing and Impacts on Chesapeake Bay Flora and Fauna The timing of tropical storms and hurricanes can have major impacts on the life histories of Chesapeake Bay flora and fauna. Changes in water salinity can cause early spawning in some species, such as the blue crab, and increased sediment can cause widespread die-off of seagrasses.   diagram,eco-rythm,storms,chesapeake,tropical,hurricanes,early,migration,timing

Conowingo Dam Reservoir and Susquehanna Flats Depiction In the section of the river above the dam builds up with sediment, making the dam shallower. High water flow causes scouring and the transport of sediment and associated nutrients over the dam.  On this other side of the dam phosphorus mobilizes in reaction with salt water.  Further down the river seagrass beds grow on the Susquehanna flats.    diagram,conowingo,dam,susquehanna,flats,sediment,deposition,scouring,sediment,transport,nutrients
