Light Reflectance, Transmittance, and Utilization Efficiency of Leaves of Mikania micrantha and Interspecies Comparison within the Same Community
薇甘菊 草本植物 木本植物 光合能力 反射率 透射率
2009/11/18
该文对薇甘菊及其所在群落内19种植物(草本和木本)的叶片透射率、反射率和光合特征指标进行了测定, 结果表明:薇甘菊与其它植物透射和反射图谱的变化趋势都比较相近, 在各个光学特征指标与光合相关指标的相互关系中, 薇甘菊并没有表现出区别于同一群落内其它植物的特征。从平均值来看, 200-800 nm下叶片反射率和透射率由大到小依次为: 薇甘菊>草本植物>木本植物, 薇甘菊各光学植被指标(SR680、S...
Nonequilibrium plankton community structures in an ecohydrodynamic model system
Nonequilibrium plankton community structures ecohydrodynamic model system
2009/11/16
Due to the local and global impacts of algae blooms and patchiness on water quality, carbon cycling and climate, models of plankton dynamics are of current interest. In this paper, the temporal and sp...

Net Loss of CaCO3 from a subtropical calcifying community due to seawater acidification:mesocosm-scale experimental evidence
CaCO3 subtropical calcifying community seawater acidification experimental evidence
2010/1/20
Acidification of seawater owing to oceanic uptake of atmospheric CO2 originating from human activities such as burning of fossil fuels and land-use changes has raised serious concerns regarding its ad...
Net community production of oxygen derived from in vitro and in situ 1-D modeling techniques in a cyclonic mesoscale eddy in the Sargasso Sea
Net community production oxygen vitro situ 1-D modeling techniques Sargasso Sea
2010/1/20
It has been proposed that the disagreement traditionally reported between in vitro incubation and in situ estimates of oxygen net community production (NCP) could be explained, at least partially, by ...
