Modelling the clonal growth of the rhizomatous macrophyte Potamogeton perfoliatus
Macrophytes play a crucial role in the functioning of lake ecosystems. Until now most macrophyte models neglected the fact that the majority of macrophyte species expand clonally during the growing season. Inclusion of a detailed description of clonal growth in models can facilitate our understanding of space occupation and patch expansion and predict future macrophyte development. “CLOMO” is a...
متن کاملComparison of methods for measuring production by the submersed macrophyte , Potamogeton perfoliatus L
Six conventional methods for measuring primary production of submersed vascular plants were compared to test for previously suggested inherent shortcomings in the O,-exchange techniques. Production was measured for experimental populations of Potamogeton perfoliatus L., from upper Chesapeake Bay in five comparative studies, each including an O,-exchange method. All techniques tested (14C incorp...
متن کاملSpatio-temporal dynamics and plasticity of clonal architecture in Potamogeton perfoliatus
Aboveand below-ground clonal growth architecture was compared for two neighbouring patches of Potamogeton perfoliatus L. in Lake Constance, representing typical sparse and dense growth types. A detailed map of individual ramets and their corresponding rhizome network was produced and the seasonal development of ramet sprouting and rhizome growth was reconstructed. Rhizomes extended at rates ran...

15 صفحه اولLeaf Form Evolution in Viburnum Parallels Variation within Individual Plants.
Few studies have critically evaluated how morphological variation within individual organisms corresponds to variation within and among species. Subindividual variation in plants facilitates such studies because their indeterminate modular growth generates multiple serially homologous structures along growing axes. Focusing on leaf form, we evaluate how subindividual trait variation relates to ...
