Combined toxicity of microplastic and lead on submerged macrophytes
Chemosphere, 2022Microplastic pollution has become ubiquitous due to industrialization and wide use of plastic products. The continuous discharge of microplastics into aquatic ecosystems, combined with different toxic chemicals can create serious environmental pollution.

Effects of Motor Boats on Submerged Aquatic Macrophytes
Lake and Reservoir Management, 1997ABSTRACT Excluding motor boats from small experimental plots in a lake with heavy boat traffic significantly increased macrophyte biomass, coverage, and shoot height compared to impacted areas. Lakes across the country are increasingly threatened by overuse, particularly involving more and larger motor boats.

The abundance of nirS-type denitrifiers and anammox bacteria in rhizospheres was affected by the organic acids secreted from roots of submerged macrophytes [PDF]
Chemosphere, 2020 Excessive nitrogen has been a global concern to cause lake eutrophication. The denitrification and anammox processes are considered to be effective biological pathways for nitrogen removal. Submerged macrophytes also play a key role in the nitrogen cycle

Determinants of submerged macrophytes palatability to grass carp Ctenopharyngodon idellus [PDF]
Ecological Indicators, 2018 Submerged macrophytes reestablishment is one of key processes in restoration of water ecological system. However, adverse effect caused by grass carp on macrophyte communities is existed during the process of ecological restoration. At present, little is

Water transport in submerged macrophytes
Aquatic Botany, 1993Abstract Compared with their terrestrial ancestors, submerged angiosperm species have a reduced but, nevertheless, well-structured vascular tissue containing xylem, phloem and an endodermis with casparian strips, thought to be important for a regulated flow of ions and water.

Microcystin production in epiphytic cyanobacteria on submerged macrophytes
Toxicon, 2010Cyanotoxins have been largely studied in planktonic and benthic cyanobacteria, but microcystin (MCYST) production in epiphytic cyanobacteria has not been reported yet. The present study reports for the first time the MCYST production in epiphytic cyanobacteria on submerged macrophytes.

PALEOECOLOGY OF SUBMERGED MACROPHYTES IN THE UPPER CHESAPEAKE BAY
Ecological Monographs, 2000Fossil seed distributions of submerged aquatic vegetation (SAV) from dated sediment cores in tributaries of the upper Chesapeake Bay show prehistoric changes in species composition and abundance and reflect the response of SAV species to human disturbance since European settlement.

Regulation of photosynthetic rates of submerged rooted macrophytes
Oecologia, 1989Fourteen temperate, submerged macrophytes were cultivated in the laboratory at high DIC levels (3.3-3.8 mM), 10.4-14.4 mol photons (PAR) m-2 d-1 and 15°C. Photosynthesis at photosaturation ranged between 0.59 and 17.98 mg O2 g-1 DW h-1 at ambient pH (8.3) and were markedly higher between 1.76 and 47.11 mg O2 g-1 DW h-1 at pH 6.5 under elevated CO2 ...

Submerged macrophytes mediated remediation of molybdenum-contaminated sediments
Environmental Science and Pollution Research, 2023Molybdenum (Mo) sourced mainly from artificial activities is an emerging environmental concern whose remediation is seldom reported. This study screened the Mo-enriched macrophyte Vallisneria natans (Lour.) Hara due to its high enrichment factor (10.25). Phytoremediation (V. natans) and microorganism-assisted phytoremediation (V.
