Seasonal comparisons of weight loss for two types of Typha glauca Godr. leaf litter
Abstract Samples of living (2.8% N, 0.3% P) and naturally senesced (0.6% N, 0.05% P) leaves of cattail (Typha glauca Godr.) were collected from a shallowly flooded stand during July 1979 and FebruaryExpand
Evaluation of translocation criteria: case study with trumpeter swans (Cygnus buccinator)

Effects of Flooding on Dissolved and Suspended Nutrients in Small Diked Marshes
Flooding ten 5- to 7-ha diked marshes in the Delta Marsh, Manitoba, to about 1 m above natural marsh levels did not increase dissolved or suspended nutrient concentrations in the surface water.Expand
Effects of Prolonged Flooding on Nektonic Invertebrates in Small Diked Marshes
This study examined the response by nektonic invertebrates to prolonged flooding of a series of experimental marshes in the Delta Marsh in south-central Manitoba. Prior to flooding, nektonicExpand
