Other common names for this plant include "Anacharis" (an older name for the genus "
"), water thyme, common
, and ditch moss.
Chemical control methods against invasive
are ineffective at eradicating
, at best, only slowing the growth for a season or two. As
spreads into new ecosystems, it experiences rapid growth for 5–6 years and then slows as soil nutrients are used up.
is now threatening all of Europe, a wait and see approach has been deemed the best method of control. Chemicals may be used in places that cause undue economic concerns, but very few aquatic herbicides are registered for aquatic use in the EU. Fluridone, the most commonly used aquatic herbicide is highly effective against Hydrilla, but only marginally effective against
, especially at lower use rates.
It is similar to its relative, "
canadensis". However the leaves taper to an acute point.
The larvae feed on "Nymphaea alba", "Potamogeton", "Callitriche", "Ceratophyllum demersum", "
canadensis", "Nuphar lutea" and "Stratiotes".
Plants such as "
" and others have been recorded from the Lagan.
canadensis", sometimes called American or Canadian water weed or pond weed, is widely known as the generic water weed. The use of these names causes it to be confused with similar-looking plants, like Brazilian
("Egeria densa") or hydrilla ("Hydrilla verticillata"). American water weed is an attractive aquarium plant and is a good substitute for Brazilian
. It can be used for science experiments in classrooms demonstrating how plants use carbon dioxide with the usage of bromothymol blue.
Some species have become established ornamental plants, and subsequently serious weeds in the wild (especially "Egeria", "
" and "Hydrilla").
"Cratoxylum celebicum" Blume, "Cratoxylum hypericum" (Blume) Merr. and "
sumatrana" Jack may refer to the same specimen.
Where oxygenation is a critical requirement "Stratiotes aloides", "Hydrocharis morsus-ranae", "Acorus calamus", "Myriophyllum" species and "
" have been used.
is a genus of 6 species of aquatic plants often called the waterweeds described as a genus in 1803. "
" is native to North and South America and is also widely used as aquarium vegetation. It lives in fresh water.
It is closely related to "
nuttallii", which generally has narrower leaves under 2 mm broad. It is usually fairly easy to distinguish from its relatives, like the Brazilian "Egeria densa" and "Hydrilla verticillata". These all have leaves in whorls around the stem; however, "
" usually has three leaves per whorl, whereas "Egeria" and "Hydrilla" usually have four or more leaves per whorl. "Egeria densa" is also a larger, bushier plant with longer leaves.
The breeding of the "
canadensis" species has been inhibited at Lake Alexandrina because of the steep slopes on the east and west sides of the lake, as well as turbulence caused by high winds of 10–14 m/s.
The first european evidence of "
nuttallii" was probably 1914 in England, though it had been determined wrongly as "Hydrilla verticillata". It is a invasive species to Europe and is now covering practically the whole continent.
The most recent phylogenetic treatment of the family recognizes four subfamilies – Hydrocharitoideae ("Hydrocharis", "Limnobium"), Stratiotoideae ("Stratiotes"), Anacharidoideae ("Apalanthe", "Appertiella", "Blyxa", "Egeria", "
", "Lagarosiphon" and "Ottelia") and Hydrilloideae ("Enhalus", "Halophila", "Hydrilla", "Maidenia", "Najas", "Nechamandra", "Thalassia" and "Vallisneria").
Goldfish, like all cyprinids, are egg-layers. Their eggs are adhesive and attach to aquatic vegetation, typically dense plants such as "Cabomba" or "
" or a spawning mop. The eggs hatch within 48 to 72 hours.
The genus was formerly included in the related genus "
", from which it differs in having the leaves in whorls of four or more, not three, and in having more conspicuous flowers with larger (particularly broader) petals.
Lagarosiphon major is a monocotic aquatic plant native to Southern Africa. Common names include African
, curly waterweed, oxygen weed and South African oxygen weed. It is used as freshwater aquarium plant.
The lake supports a range of pondweeds that include "Potamogeton perfoliatus" and "P. lucens", Canadian pondweed ("
canadensis"), and a variety of stoneworts ("Chara" spp., such as "C. pedunculata" and "C. curta") which are marl or hard-water lake indicators.
Aquatic vegetation on the shores is represented by reeds of "Scirpus" spp. and aquatic herbs like watercress, "
potamogeton" and "Myriophyllum" sp. While the surrounding meadows include plants of the genera Carex and Calamagrostis.
Gellan gum is a water-soluble anionic polysaccharide produced by the bacterium "Sphingomonas
" (formerly "Pseudomonas
"). The gellan-producing bacterium was discovered and isolated by the former Kelco Division of Merck & Company, Inc. in 1978 from the lily plant tissue from a natural pond in Pennsylvania, USA. It was initially identified as a substitute gelling agent at significantly lower use level to replace agar in solid culture media for the growth of various microorganisms Its initial commercial product with the trademark as "GELRITE" gellan gum, was subsequently identified as a suitable agar substitute as gelling agent in various clinical bacteriological media.
