Abstract:
... Gases were extracted from the internal atmosphere of Elodea canadensis and Ceratophyllum demersum in a closed system under reduced pressure. The volume of extractable gases varied throughout the daily period. Gases separated and quantitatively measured by gas chromatography included CO₂, O₂, N₂, and CH₄. Results from diurnal studies showed a lag between peak values for dissolved oxygen in the surr ...

Abstract:
... This study investigated the community structure of ammonia‐oxidizing bacteria /archaea (AOB and AOA), as well as the effects of four aquatic plants (namely Ceratophyllum demersum, Hydrilla verticillata, Potamogeton crispus, and Nymphaea tetragona) rhizospheres on the abundance of AOB amoA, AOA amoA, anammox 16S rRNA, nirK, and nirS in Lake Liangzi, China. Phylogenetic analysis revealed that most A ...

Abstract:
... We examined temporal changes in spatial patterns of submersed aquatic vegetation (SAV) in response to the restoration of geomorphic habitat in Navigation Pool 8 of the Upper Mississippi River from 1998 to 2016. The frequency of occurrence and species composition of SAV at sampling sites were spatially interpolated for each year to create annual maps. Linear models were fitted to temporal changes i ...

Abstract:
... The Shallow Lakes Restoration Project aims to restore eutrophic shallow lakes throughout the Iowa Prairie Pothole Region (PPR). We compared the vegetation taxa richness and frequency of taxa in three vegetation groups surveyed in 2016 and 2017 across non-restored sites, younger restorations, and older restorations. We also assessed the impact of these groups on numbers of breeding marsh birds. Res ...

Abstract:
... Ceratophyllum demersum is a submerged aquatic angiosperm which is fast growing in contaminated water. This plant has no roots and so takes up nutrients from the water column without the complicating factor of differential shoot/root uptake of nutrients. This study aimed to compare the bioaccumulative capacities of Cu, Zn and their combination by C. demersum and physiological responses (growth, chl ...

Abstract:
... As a new and efficient selective pre-emergence herbicide, flurochloridone (FLC) has been widely promoted in recent years but readily results in residues in nature. As the primary producers and restorers of the water environment, aquatic plants are at risk of FLC exposure. In the present research, we studied the phytotoxicity of FLC in Lemna minor and Ceratophyllum demersum. The physiological and g ...

Abstract:
... The dispersal of aquatic plant propagules is highly facilitated in streams due to flow. As many aquatic plants predominantly spread through vegetative propagules, the specific retention and thus drift distance of dispersed plant fragments largely contribute to the rapid spread along the course of a stream. We determined fragment retention for four aquatic plant species (Elodea canadensis, Myriophy ...
