Fungal endophytes in spotted knapweed influence its competitive interactions
Fungal endophytes in spotted knapweed influence its competitive interactions. Abstract Fungal symbionts are often overlooked in studies of plant invasion. Nevertheless, their role could be essential to the competitive success of the invader. We studied fungal endophytes in the widespread invasive Centaurea stoebe (common knapweed). A preliminary experiment showed that endophytes in roots of C. ...
متن کاملMolasses as an Energy Source for Sheep
Diets based on molasses as the principle source of energy for cattle are well established (Preston and Willis 1974). However, the use of molasses as an energy source for sheep, particularly under drought conditions, has not been studied extensively. The main purpose of the studies reported here was to measure the intake and production of sheep given diets containing a high proportion of molasse...
متن کاملTrained Dogs Outperform Human Surveyors in the Detection of Rare Spotted Knapweed
Invasive plants have devastating effects on ecosystems and biodiversity that early intervention can prevent. Eradication or containment of new invasions is difficult to achieve because of constraints posed by the low density and detectability of individuals. Domestic dogs trained to cue on distinctive scents might provide an effective method to detect spotted knapweed. The objective of this stu...
متن کاملThe case against (-)-catechin involvement in allelopathy of Centaurea stoebe (spotted knapweed).
Proving allelopathic chemical interference is a daunting endeavor, in that production and movement of a phytotoxin from a donor plant to a receiving plant must be demonstrated in the substrate in which the plants grow, which is usually a complex soil matrix. The soil levels or soil flux levels of the compound generated by the donor must be proven to be sufficient to adversely affect the receivi...
متن کاملMaculosin, a host-specific phytotoxin for spotted knapweed from Alternaria alternata.
Several diketopiperazines have been isolated from liquid cultures of Alternaria alternata, the causal agent of black leaf blight of spotted knapweed, Centaurea maculosa Lam. One of these compounds, maculosin [the diketopiperazine cyclo(-L-Pro-L-Tyr-)], was active in the nicked-leaf bioassay at 10(-5) M; synthetic maculosin possessed chemical and biological activities identical to those of the n...
