phalaris aquatica การใช้

• The spider hides under rocks and crevices on this volcanic island, but its habitat is being invaded by the grass " Phalaris aquatica ", while the native vegetation is damaged by introduced goats and rabbits.
• Significant weeds recorded include St John s Wort " Hypericum perforatum ", Serrated Tussock " Nassella trichotoma ", African Lovegrass " Eragrostis curvula " and Phalaris " Phalaris aquatica ".
• These include velvet grass ( " Holcus lanatus " ), tall fescue ( " Festuca arundinacea " ), and Harding grass ( " Phalaris aquatica " ); the impact of these species can be somewhat ameliorated by well-planned livestock grazing, which can reduce these species'cover and allow native species to persist.
• From experiments aimed at identifying the toxin responsible for producing the locomotor disorder ( " staggers " ) and rapidly lethal cardiac toxicosis ( " sudden death " ) periodically observed in livestock feeding on the grass " Phalaris aquatica ", Australian researchers determined that the lowest doses of hordenine that would induce symptoms of " staggers " in sheep were 20 mg / kg i . v ., and 800 mg / kg orally.
