Can allelopathically active submerged macrophytes stabilise clear-water states in shallow lakes?

Inhibition of phytoplankton by allelochemicals released by submerged macrophytes is supposed to be one of the mechanisms that contribute to the stabilisation of clear-water states in shallow lakes. The relevance of this process at ecosystem level, however, is debated because in situ evidence is difficult to achieve. Our literature review indicates that allelopathically active species such as My...

Mowing Submerged Macrophytes in Shallow Lakes with Alternative Stable States: Battling the Good Guys?

Submerged macrophytes play an important role in maintaining good water quality in shallow lakes. Yet extensive stands easily interfere with various services provided by these lakes, and harvesting is increasingly applied as a management measure. Because shallow lakes may possess alternative stable states over a wide range of environmental conditions, designing a successful mowing strategy is ch...

Multielement stoichiometry of submerged macrophytes across Yunnan plateau lakes (China)

Stoichiometric homeostasis of element composition is one of the central concepts of ecological stoichiometry. We analyzed concentrations of macroelements (C, N, P, Ca, K, Mg, S), microelements (Cu, Fe, Mn, Mo, Ni, Zn) and beneficial elements (Na, Se, Si) in submerged macrophytes, water and sediments across 20 Yunnan plateau lakes. We predicted that tissue element composition in submerged macrop...

Spectral Discrimination of Submerged Macrophytes in Lakes Using Hyperspectral Remote Sensing Data

Submerged macrophytes give important information about a lake ́s trophic state and its ecosystem. Aquatic macrophytes can therefore serve as useful indicators of water pollution along the littoral zones. The spectral signatures of various macrophyte species were investigated to determine whether species could be discriminated by remote sensing. The spectral reflectance of macrophytes collected f...
