Effects of the introduced floating vascular aquatic Hydrocharsis morsus-ranae Hydrocharitaceae on some North American aquatic macrophytes. Although of little economic importance, these herbaceous plants provide important habitats for fish and help stabilize shorelines. Knowledge of the extent and structure of genetic diversity and a speciesâ ecological niche are integral to formulating management plans for the conservation of threatened species. The most important thing to remember when using botanical terms is that just because some aspect of an organism is dignified by a sesquipedalian word, this by no means signifies that the term refers to an interesting part of "reality" (see also Kirchoff et al. Because grasses are of great economic importance, there have been a few studies of their leaf mesophyll oil bodies, beginning with the earliest observations (despite his misleading dissertation title) from several species by Monteverde (1890).

Because hydrilla is highly invasive and can cause severe economic and ecological damages, it has raised great concerns from ecologists and environmental managers.
