Article Abstract:
Silvicultural practices such as gapping and thinning of young-growth forest enhance and maintain habitat for breeding and wintering birds in the temperate rainforests of Prince of Wales Island, southeast Alaska. The breeding bird species between young- and old-growth treatments are less similar than those among young-growth treatments. Winter severity determines the higher use of old-growth by wintering birds. Thinning young-growth to create more canopy layers, retaining old-growth in clearcuts, and conserving the old-growth temperate rainforest can enhance the bird habitats.

Article Abstract:
The genetic mating system of the Dusky Antbird, a tropical passerine, was studied using multilocus DNA fingerprinting. This technique is a powerful molecular method that assesses genetic mating systems according to behavioral patterns. Results reveal no evidences of extra-pair fertilization among the samples utilized. Furthermore, there were no signs of specific brood parasitism for other samples as well.
