Ebullition is an important pathway for transport of methane (CH) to the atmosphere in wetlands. Water level changes have been suggested to trigger ebullition, especially in tidally flooded areas, although the controlling mechanisms remain uncertain. Bubble transport in submerged sediment represents a ...
A metacommunity is a set of local communities linked by the dispersal of multiple interacting plant species within a landscape or region, and these local communities often occur in different habitats, such as valleys, hills, river beaches, wetlands, and deltas. Habitat heterogeneity (i.e., ...
After carbon monoxide, it is the largest sink of the hydroxyl radical (OH) and therefore plays a significant role in determining the oxidizing capacity of the global troposphere. Emissions are from wetlands, agriculture (e.g., rice paddies, ruminants, and waste), anthropogenic emissions (e.g....
In what way are the wetlands important? Why is density dependence important in multicellular organisms? Why is seed dispersal important in the life of plants. What would be the consequences of having seeds that simply fell to the ground underneath the parent tree? Describe how polluti...
A loss of biodiversity due to an invasive What happens to the net primary productivity and to the species diversity when humans disrupt wetlands by adding more nutrients, as in the example of agriculture in the Everglades? What...
Coastal wetlands of southern Ontario are highly fragmented and exist as islands within a primarily urbanized and agricultural matrix. Given the large varia... LA Smith,P Chow-Fraser - 《Wetlands》 被引量: 2发表: 2010年 Differences in Habitat at Two Spatial Scales Fail to Predict Differing Occur...
Indeed, interactions between salinity and hydroperiod have been implicated in the regulation of survival, growth, physiological proficiency, and zonation of individual seedlings, saplings, and trees that colonize mangrove wetlands [10, 11]. Through repetitive experimentation, we are progressively gaining ...
Our findings demonstrate the importance of effective stress changes in triggering ebullition from mudflat areas in tidal wetlands, modulated by the mechanical properties of shallow soft sediments.ChenXi 1SlaterLee 2 1 State Key Laboratory of Earth Surface Processes and Resource Ecology...
We examined patterns of metaphyton community composition from 150 sites in spring wetlands of the Bonneville Basin across three spatial scales: valleys, wetlands nested in valleys, and habitat types nested in wetlands (springs, channels, and marshes) to determine which scale(s) accounted for the ...
Wetlands are disappearing faster than any other ecosystem. Germany has one of the worlds highest rates of wetland losses. From a legal perspective, the significant extent of these degradations since 1976 is symptomatic of the inadequate incorporation of the Ramsar Convention into the German legal ...
