Vegetation of wetlands of the prairie pothole region
Five themes dominate the literature dealing with the vegetation of palustrine and lacustrine wetlands of the prairie pothole region: environmental conditions (water or moisture regime, salinity), agricultural disturbances (draining, grazing, burning, sedimentation, etc.), vegetation dynamics, zonation patterns, and classification of the wetlands.The flora of a prairie wetland is a function of its

Prairie basin wetlands of the Dakotas: a community profile
This description of prairie basin wetlands of the Dakotas is part of a series of community profiles on ecologically important wetlands of national significance. The shallow wetlands of the Dakotas form the bulk of the portion of the Prairie Pothole Region lying within the United States. This region is famous as the producer of at least half of North America's waterfowl and an unknown, but large, p

Dispersal in the communally breeding groove-billed ani (Crotophaga sulcirostris)
We studied dispersal in a color-banded population of the Groove-billed Ani (Crotophaga sulcirostris) in Costa Rica. Eight percent of the young alive at the end of the breeding season bred on their natal territories the next year and 4% remained but did not breed. Thirteen percent dispersed successfully within the study area and bred in communal groups or simple pairs. The remaining 75% of the youn

Rice available to waterfowl in harvested fields in the Sacramento Valley, California
Rice fields in the Sacramento Valley, California were sampled in 1985 and 1986 to determine the weight of rice seed remaining in the fields immediately after harvest and again after the fields were burned. No significant differences were found between years (P>0.05). The pooled mean was 388 kg/ha in harvested fields and 276 kg/ha in burned fields. These values are less than estimates previously av

Wetland bird seasonal abundance and habitat use at Lake Earl and Lake Talawa, California
A study of wetland bird composition, seasonal abundance, and habitat use was conducted on Lake Earl and Lake Talawa in Del Norte County, California from July 1974 through February 1976. Ninety-five species were recorded. Most birds occurred from October to December and during March and April. Diving ducks occurred primarily during fall and winter and were more abundant than surface-feeding waterfo

Carbonate deposition on tail feathers of ruddy ducks using evaporation ponds
Substantial carbonate deposits were observed on rectrices of Ruddy Ducks (Oxyura jamaicensis) collected during 1982-1984 on evaporation ponds in the San Joaquin Valley, California. Carbonate deposits were composed of about 75% aragonite and 25% calcite, both polymorphous forms of CaCO3. Significantly more carbonate deposits were observed on Ruddy Ducks as length of exposure to agricultural drain w

Importance of individual species of predators on nesting success of ducks in the Canadian prairie pothole region
We followed 3094 upland nests of several species of ducks. Clutches in most nests were lost to predation. We related daily nest predation rates to indices of activity of eight egg-eating predators, precipitation during the nesting season, and measures of wetland conditions. Activity indices of red fox (Vulpes vulpes), striped skunk (Mephitis mephitis), and raccoon (Procyon lotor) activity were pos
