Tidal day organic and inorganic material flux of ponds in the Liberty Island freshwater tidal wetland
The loss of inorganic and organic material export and habitat produced by freshwater tidal wetlands is hypothesized to be an important contributing factor to the long-term decline in fishery production in San Francisco Estuary. However, due to the absence of freshwater tidal wetlands in the estuary, there is little information on the export of inorganic and organic carbon, nutrient or phytoplan...
متن کاملWetland seed dispersal by white-tailed deer in a large freshwater wetland complex
Mechanisms of long-distance dispersal are important in establishing and maintaining plant populations in isolated wetland habitats. White-tailed deer (Odocoileus virginianus) have been cited as long-distance dispersers of both native and exotic plant species in North America; however, knowledge regarding their influence in wetlands is limited. Given traditional classification methods for seed d...
متن کاملEvolutionary dynamics of seed size and seedling competitive ability.
We present a model for the evolutionary dynamics of seed size when there is a trade-off between seed size and seed number, and seedlings from large seeds are better competitors and have a higher precompetitive survival than seedlings from small seeds. We find that strong competitive asymmetry, high resource levels, and intermediate harshness of the precompetitive environment favor coexistence o...
متن کاملThe Relationship between Aboveground and Belowground Biomass of Freshwater Tidal Wetland Macrophytes
Whigham, D.F. and Simpson, R.L., 1978. The relationship between aboveground and belowground biomass of freshwater tidal wetland macrophytes. Aquat. Bot., 5: 355--364. Aboveground and belowground biomass relationships of 15 annual and perennial freshwater tidal wetland macrophytes were examined. The data showed that regression equations may be used with confidence to estimate belowground biomass...
متن کاملFreshwater Wetland Resources and Biology
The term “wetlands” means those areas that are inundated or saturated by surface water or groundwater at a frequency and duration sufficient to support a prevalence of vegetation typically adapted for life in saturated soil conditions. They are located at the ecotones between dry terrestrial ecosystems and permanently wet aquatic ecosystems. As such, they have an intermediate hydrology, a bioch...
