Seasonal nutrient fluxes variability of northern salt marshes: examples from the lower St. Lawrence Estuary
Springer Science and Business Media LLC - - 2009
This study presents the tidal exchange of ammonium, nitrite + nitrate, phosphate and silicate between two salt marshes and adjacent estuarine waters. Marsh nutrient fluxes were evaluated for Pointe-au-Père and Pointe-aux-Épinettes salt marshes, both located along the south shore of the lower St. Lawrence Estuary in Rimouski area (QC, Canada). Using nutrients field data, high precision bathymetric ...... hiện toàn bộ

To the importance of genetic diversity of Phragmites australisin the development of reed stands
Springer Science and Business Media LLC - Tập 8 - Trang 403-414 - 2000
Reed stands in Germany and Europe were investigatedwith respect to their genetic diversity by means ofRandom Amplified Polymorphic DNA (RAPD) via thePolymerase Chain Reaction (PCR-fingerprinting).Different types of clonal distribution could bedistinguished: monoclonal reed stands and polyclonalreed stands, and among the latter, stands with low orhigh numbers of different clones as well as standswi...... hiện toàn bộ
Tidal asymmetry in creeks surrounded by saltflats and mangroves with small swamp slopes
Springer Science and Business Media LLC - Tập 8 - Trang 223-232 - 2000
Most mangrove swamp/salt flat systems have tidal currents that are ebb dominated, however, some systems show only slight ebb dominance despite having a very large swamp volume relative to the creek volume. Cocoa Ck in northern Australia is such a system. Results are presented from a simple analytical model for flow in Cocoa creek together with detailed water level observations in the swamps. It wa...... hiện toàn bộ
Use of dredge islands by a declining European shorebird, the Kentish Plover Charadrius alexandrinus

The role of salt marshes in the Mira estuary (Portugal)
Springer Science and Business Media LLC - Tập 9 - Trang 121-134 - 2001
The Mira estuary is a narrow entrenched pristine estuary of the Ria type, about 30 km long. It comprises an area of 285 ha of salt marsh, of which250 ha have been proposed for reclamation for aquaculture. Dredging, village and recreation development menace the yet undisturbed estuarine ecosystem. To assess the biological importance of this wetland, a multidisciplinary study was conducted in apart ...... hiện toàn bộ
Aquatic ecosystem responses to fire and flood size in the Okavango Delta: observations from the seasonal floodplains
Springer Science and Business Media LLC - - 2010
The frequency of fires in the Okavango Delta seasonal floodplains peaked at an intermediate frequency of flooding. Floodplains are commonly burnt every 3–5 years. This study showed fundamental changes in ecosystem properties due to burning. A burnt seasonal floodplain in the aquatic phase had oxygen levels well above saturation, 100–200%, while the levels in the un-burnt control site were below sa...... hiện toàn bộ
Short-term changes in soil nutrients during wetland creation
Springer Science and Business Media LLC - Tập 6 - Trang 203-208 - 1998
This study examined changes in pH and extractable nutrients in soilsfollowing wetland creation. Sample plots were established in two areas: (1) an old-field with parts that were flooded during wetland creation, and (2) a native wetland in a floodplain of the Ohio River called Green Bottom Swamp. Soils were sampled before inundation and eight months afterwards. Compared to old-field soils in the pr...... hiện toàn bộ
Impacts of recreation management practices in a subalpine wetland system dominated by the willow plant, Salix planifolia
Springer Science and Business Media LLC - Tập 26 - Trang 119-124 - 2017
Wetland habitat in the subalpine Rocky Mountains is an area of high biodiversity and includes many species of willow. These willow-dominated communities are often used for both summer and winter recreation. The maintenance of winter recreation trails has the potential to disturb wetland vegetation and compromise the long-term persistence of the wetland. In Breckenridge, Colorado, willow plants are...... hiện toàn bộ
