Use of sediment CO2 by submersed rooted plants [PDF]

open access: yesAnnals of Botany, 2009
Submersed plants have different strategies to overcome inorganic carbon limitation. It is generally assumed that only small rosette species (isoetids) are able to utilize the high sediment CO(2) availability. The present study examined to what extent five species of submersed freshwater plants with different morphology and growth characteristics ...

Competitive Interactions of Flowering Rush (Butomus umbellatus L.) Cytotypes in Submersed and Emergent Experimental Aquatic Plant Communities

open access: yesDiversity, 2020
The ability to invade communities in a variety of habitats (e.g., along a depth gradient) may facilitate establishment and spread of invasive plants, but how multiple lineages of a species perform under varying conditions is understudied.

Aquatic vegetation types identified during early and late phases of vegetation recovery in the Upper Mississippi River

open access: yesEcosphere, 2023
Assemblage patterns and processes of aquatic vegetation in most large floodplain rivers are not well understood, particularly after plant recovery. Identifying vegetation types, which are recurring plant groupings based on species composition, diversity,

Comparison of the Photosynthetic Characteristics of Three Submersed Aquatic Plants [PDF]

open access: yesPlant Physiology, 1976
Light- and CO(2)-saturated photosynthetic rates of the submersed aquatic plants Hydrilla verticillata, Ceratophyllum demersum, and Myriophyllum spicatum were 50 to 60 mumol O(2)/mg Chl.hr at 30 C. At air levels of CO(2), the rates were less than 5% of those achieved by terrestrial C(3) plants. The low photosynthetic rates correlated with low activities

The influence of Brazilian plant extracts on Streptococcus mutans biofilm

open access: yesJournal of Applied Oral Science, 2014
Nineteen plant extracts obtained from plants from the Brazilian Amazon showed activity against planktonic Streptococcus mutans, an important bacterium involved in the first steps of biofilm formation and the subsequent initiation of several oral diseases.

Termite species list in a terra firme and ghost forest associated with a hydroelectric plant in Presidente Figueiredo, Amazonas, Brazil [PDF]

open access: yesCheck List, 2012
Termites are among the most important groups to maintain tropical forests but despite their importance they are poorly studied. Termites were sampled in the trunks left over from the flood period in the Balbina Hydroelectric plant (UHB).

Visual Inspection Submersible for Nuclear Power Plant.

open access: yesJournal of the Atomic Energy Society of Japan / Atomic Energy Society of Japan, 1996
Remotely Operated Vehicles (ROV) are currently in use for visual inspections within reactor pressure vessels (RPV). In boiling water reactors (BWR), there is a complex RPV consisting of structures which are not disassembled during outages. To inspect the large volume of the RPV and associated components, the inspection vehicle must be compact and ...
