A survey of fungi associated with lesioned and chlorotic sago pondweed (Potamogeton pectinatus) A survey of fungi associated with lesioned and chlorotic sago pondweed (Potamogeton pectinatus)
Isolations from 1000 Potamogeton pectinatus plants collected from six major stands in Back Bay, Virginia and 13 in Currituck Sound, North Carolina yielded Pythium spp. consistently and in relatively high frequency. Although specific determination of these isolates was unsuccessful, they were separated into three groups according to morphological and cultural characteristics. Rhizoctonia...

Nesting ecology and reproductive rate of the red-winged blackbird in tidal marshes of the upper Chesapeake Bay region Nesting ecology and reproductive rate of the red-winged blackbird in tidal marshes of the upper Chesapeake Bay region
The nesting ecology and reproductive rate of the polygynous red-winged blackbird, Agelaius phoeniceus, were studied in the tidal marshes of Maryland during the period of 1958 through 1961. Sixteen nesting colonies were located in six major marsh communities of the Eastern Shore and were visited approximately twice a week from late April to mid-August. The average clutch size for 537...

Pellet casting by king and clapper rails Pellet casting by king and clapper rails
The King Rail (Rallus elegans) and Clapper Rail (Rallus longirostris), whose major food is crustaceans, reject the exoskeletal fragments of these animals through the regurgitation of pellets. Seven King Rail pellets collected in Dorchester County, Maryland, averaged 2.0 cm long by 1.5 cm wide.
