Variation of Ceratophyllum Demersum in Eastern Kansas
Transactions of the Kansas Academy of Science (1903-), 1951Field observations in the state reveal that Ceratophyllum demersum L. is a much more common plant than our records show. Gates (1940) lists the plant from eight scattered counties. The writer has, however, found the species in many Kansas counties and feels certain that it occurs throughout the state in suitable habitats.

Ceratophyllum demersum – phosphorus interactions in nutrient enriched aquaria
Hydrobiologia, 2003High macrophyte density in shallow lakes is often associated with clear water, especially when the non-rooted, submerged angiosperm Ceratophyllum demersum is dominant. Lack of true roots and high surface area:volume ratio suggest that nutrient uptake from the water column by C. demersum may be high.

Growth Substances and Dormancy in Ceratophyllum demersum
Physiologia Plantarum, 1979Abstract Ceratophyllum demersum L. occurs in winter in the dormant form, in summer in the vegetative form. Factors that affect growth and dormancy in Ceratophyllum were studied. After several weeks of severe winter conditions the plants changed from dormant to quiescent state.

The kinetics of NH4 uptake by Ceratophyllum
Hydrobiologia, 1973The relationship between growth of aquatic plants and their nutrient supply is poorly understood, because of the lack of suitable models which could be tested in the field. The purpose of this research was to learn if the Michaelis-Menten expression describes the relationship between the uptake of NH4 by Ceratophyllum and the concentration of NH4 in ...

Photosynthetic characteristics of the submerged macrophyte Ceratophyllum demersum
Physiologia Plantarum, 1986The photosynthetic and growth characteristics of Ceratophyllum demersum L. were investigated under laboratory conditions which simulated those encountered in the plants' normal environment. The carbon fixation rate of C. demersum measured with 14C at light and carbon saturation at pH 8.0 was 4.48 mg C (g ash‐free dry weight)−1 h−1. It was lower at pH 6.

Charophyte occurrence in Ceratophyllum demersum stands
Hydrobiologia, 2014The hornwort Ceratophyllum demersum is a loosely attached to the bottom or free-floating vascular macrophyte, which builds dense stands in nutrient-rich waters. The hornwort stands are usually monospecific communities with a negligible contribution of other aquatic plants.

Ceratophyllum submersum L. in Nederland
1961Up to 1954 Ceratophyllum submersum L. was represented in the Netherlands herbaria mainly from a few localities in the neighbourhood of the coast, and in the living state it was practically unknown to Dutch botanists. As appears from an investigation since 1954, this species still occurs in several localities in the coastal area, and is fairly common in
