Factors affecting the distribution patterns of aquatic macrophytes

open access: yesLimnological Review, 2014
Aquatic macrophytes constitute important components of many freshwater ecosystems. The manifold role of aquatic macrophytes in freshwater habitats is closely linked to their distribution, which in turn depends on a myriad of factors.

Control of algal growth by macrophytes and macrophyte-extracted bioactive compounds

open access: yesWater Science and Technology, 1996
Algae (Selenastrum capricornutum and Microcystis aeruginosa) were respectively assayed in a mixed-culture system using various concentrations of macrophytes obtained from Egeria densa, Cabomba caroliniana, and Myriophyllum spicatum in order to evaluate their inhibitory effects on algal growth due to possible secretion of anti-algal bioactive compounds ...

Analyse multi-compartiments et rôles fonctionnels des macrophytes dans les hydrosystèmes

open access: yesSciences, Eaux & Territoires, 2008
Les macrophytes sont mis en relation avec les autres compartiments des hydrosystèmes, tant abiotiques (masse d'eau, milieu physique) que biotiques (algues épiphytes, invertébrés, poissons).

The effects of water depth on the growth of two submerged macrophytes in an in situ experiment

open access: yesJournal of Freshwater Ecology, 2021
An in situ experiment was designed in which Potamogeton crispus and Hydrilla verticillata were planted in plastic pots 25, 50, 75, 100, 125, 150, 175 and 200 cm underwater to study the effect of water depth on the growth and photosynthetic fluorescence ...

Ecological biomechanics of marine macrophytes

open access: yesJournal of Experimental Botany, 2022
AbstractMacroalgae and seagrasses in coastal habitats are exposed to turbulent water currents and waves that deform them and can rip them off the substratum, but that also transport essential water-borne substances to them and disperse their propagules and wastes.

Effects of water temperature on summer periphyton biomass in shallow lakes: a pan-European mesocosm experiment [PDF]

open access: yes, 2015
Periphyton communities play an important role in shallow lakes and are controlled by direct forces such as temperature, light, nutrients, and invertebrate grazing, but also indirectly by planktivorous fish predation.

Ecological study of chalk streams. Lambourn project. Interim report October 1977 to April 1979 [PDF]

open access: yes, 1979
Few detailed studies have been made on the ecology of the chalk streams. A complex community of plants and animals is present and much more information is required to achieve an understanding of the requirements and interactions of all the species. It is

Oligochaeta (Annelida, Clitellata) in the Aquatic Macrophytes in Dam of Ribeirão of Anhumas Screamers (Américo Brasiliense-Sp)

open access: yesRevista Brasileira Multidisciplinar - ReBraM /Brazilian Multidisciplinay Journal, 2014
Macrophytes have different morphological structural complexities, offering to animals the availability of various niches. These plants are also an important substrate for the development of periphyton, which has a high nutritional value and is one of the
