Use of dredged material substrates by nesting terns and black skimmers
Article Abstract:
Research focusing on black skimmers and gull-billed terns, and to a lesser extent on least terns, in the Atchafalaya Delta, the only actively building delta in the northern Gulf of Mexico, has established that shell substrates play a significant role in reproductive success. Nests of black skimmers and gull-billed terns are harder to find on shell than on fine-textured dredged materials, thus making them less vulnerable to predators. Black skimmers have no preference for substrates, but this does not mean that the presence of shell has no impact on this species.

Habitat use and nest success of overwater nesting ducks in westcentral Minnesota
Article Abstract:
Patterns of nest habitat use and nest success among five duck species in westcentral Minnesota were studied. Using a canonical discriminant function analysis, the similarities and differences in the nest habitat use of redheads, ruddy ducks, mallards, ring-necked ducks, and canvasback were examined. The redheads and ruddy ducks preferred to nest in more open, larger wetlands while most mallards and ring-necked ducks chose smaller, shallower wetlands. Canvasbacks nested in wetlands of average size, depth and proportion of basin covered by overwater habitat.

Further evaluation of the genetic consequences of translocations on southeastern white-tailed deer populations
Article Abstract:
The Mantel matrix correlation can be used to gain an insight into links between the matrix of genetic distances among southeastern white-tailed deer populations and the matrices of translocation history. The matrix comparisons support the view that translocations influence the genetic structure of deer populations. It seems that restocking has a positive impact in encouraging recovery of at least some recipient populations.
