Allelopathy of aquatic autotrophs
|
ABSTRACT: Allelopathy in aquatic environments may provide a competitive advantage to angiosperme, algae, or cyanobacteria in their interaction with other primary producers. Allelopathy can influence the competition between different photoautotrophs for resources and change the succession of species, for example, in phytoplankton communities. Field evidence and laboratory studies indicate that allelopathy occurs in all aquatic habitats (marine and freshwater), and that all primary producing or...

Allelopathic interactions between sponges on a tropical reef.
Ecology
; INTRODUCTION Predation and competition for space are among the most important processes that influence the structure of marine benthic communities (Menge and Farrell 1989, Paine 1994). Predation is a major source of mortality for benthic organisms and, in the absence of an escape response, it must

Plant phenolics in allelopathy.
The Botanical Review
; II. Introduction Allelopathy, as defined by Rice (1984) is any direct or indirect beneficial or harmful effect of one plant (including microorganisms) on the other through release of chemicals into the environment. The term allelochemicals derives from allelochemics, coined by Whittaker and Feeny

Evidence of tissue-specific allelopathic activity in euthamia graminifolia and Solidago canadensis (Asteraceae)
The American Midland Naturalist
; ABSTRACT.-Euthamia graminifolia and Solidago canadensis may be found growing in dense, essentially monospecific, stands. One hypothesis to explain this phenomenon is that both of these goldenrods, as do many related taxa in Asteraceae, release allelochemicals into the surrounding environment. To

Polyphenolic allelochemicals for the aquatic angiosperm Myriophyllum spicatum inhibit photosystem II
Plant Physiology
; Myriophyllum spicatum (Haloragaceae) is a highly competitive freshwater macrophyte that produces and releases algicidal and cyanobactericidal polyphenols. Among them, /3-1,2,3-tri-O-galloyl-4,6-(S)-hexahydroxydiphenoyl-D-glucose (tellimagrandin II) is the major active substance and is an effective

Weed and crop allelopathy
Critical Reviews in Plant Sciences

Enrichment can stabilize population dynamics: autotoxins and density dependence.
Ecology
; INTRODUCTION Understanding the factors that influence population stability and variability is a major goal of population ecology. Many theoretical models predict that enrichment, such as the addition of nutrients, will reduce population stability and cause complex dynamics. Simple models of
