Cryopreservation of crane semen Cryopreservation of crane semen
The method for the cryopreservation of crane semen at Patuxent Wildlife Research Center is described in detail. Cryopreservation is useful for the long-term storage of crane semen and for specialized propagation needs. A 50% fertility rate from most sandhill cranes, Grus canadensis, inseminated with frozen-thawed semen can be expected. Additional research should improve the fertility...

Approaches to the conservation of coastal wetlands in the Western Hemisphere Approaches to the conservation of coastal wetlands in the Western Hemisphere
Coastal wetlands rank among the most productive and ecologically valuable natural ecosystems on Earth. Unfortunately, they are also some of the most disturbed. Because they are productive and can serve as transportation arteries, coastal wetlands have long attracted human settlement. More than half of the U.S. population currently lives within 80 km of its coasts, and one estimate places...

Growth rates of great egret, snowy egret and black-crowned night-heron chicks Growth rates of great egret, snowy egret and black-crowned night-heron chicks
Growth rates of Great Erget (Casmerodius albus), Snowy Erget (Egretta thula), and Black-crowned Night-Heron (Nycticorax nycticorax) chicks to 18 days-of-age were estimated from repeated measurements of chicks in broods of three young. Weight gain (g/day) or increase in length (mm/day) of forearm, tarsus, or culmen did not between Black-crowned Night-Heron chicks at a colony in Rhode...

A vacuum-operated pore-water extractor for estuarine and freshwater sediments A vacuum-operated pore-water extractor for estuarine and freshwater sediments
A vacuum-operated pore-water extractor for estuarine and freshwater sediments was developed and constructed from a fused-glass air stone attached with aquarium airline tubing to a 30 or 60 cc polypropylene syringe. Pore water is extracted by inserting the air stone into the sediment and creating a vacuum by retracting and bracing the syringe plunger. A hand-operated vacuum pump attached...

Ethyl parathion in wetlands following aerial application to sunflowers in North Dakota Ethyl parathion in wetlands following aerial application to sunflowers in North Dakota
An operational aerial application of parathion to sunflower fields resulted in greater or equal spray deposit in wetlands adjacent to or surrounded by sunflower fields than in the sunflower fields. In another application, when the applicator attempted to avoid contamination of the wetlands, parathion still drifted into wetlands in detectable amounts; in 2 of 4 comparisons, spray deposit...

Social organization in deer: Implications for localized management Social organization in deer: Implications for localized management
Populations of white-tailed deer (Odocoileus virginianus) inhabiting many state and national parks and suburban areas have grown to the point that they conflict with human activities. Conflicts range from destruction of vegetation through browsing to public perception that diseases carried by deer pose threats to human health. Traditional modes of hunting to control populations are...
