The pyrrolizidine alkaloids (PAs) and ergot alkaloids are known natural toxicants found in livestock forage. These alkaloids contribute to large economic losses in livestock throughout the world. An understanding of the mechanisms of toxicity and development of better diagnostic tools for better management practices was investigated. Variability exists in the...
Ergovaline is an ergot alkaloid produced by the symbiotic endophyte Epichloë coenophiala which can colonize varieties of the cool-season grass tall fescue (Festuca arundinacea). It is the principle toxicant responsible for the vasoconstrictive and reproductive sequelae seen in “fescue toxicosis” in livestock which consume forage exceeding the threshold of toxicity...
Perennial ryegrass (Lolium perenne) hay is an important source of forage for a variety of livestock species, and is most common in cool, coastal climates such as the Pacific Northwest. An endophyte fungus called Neotyphodium lolii frequently colonizes this grass to promote insect resistance, drought tolerance, and growth enhancement without...

The manufacturing processes of royal demolition explosive (RDX), or hexahydro-1,3,5-trinitro-1,3,5-triazine, have resulted in
serious water contamination. As a potential carcinogen, RDX can cause a broad range of harmful effects to humans and
animals. The ovine rumen is capable of rapid degradation of nitroaromatic compounds, including RDX. While ruminal RDX-degrading
bacteria...

Plant species in the family Solanaceae are the usual hosts of potato psyllid, Bactericera cockerelli (Sulc) (Hemiptera: Psylloidea: Triozidae). However, the psyllid has also been shown to develop on some species of Convolvulaceae (bindweeds and morning glories). Developmental success on Convolvulaceae is surprising given the rarity of psyllid species worldwide...
The essential oil from two Lantana species (Lantana lucida Schauer and Lantana salzmannii Schauer) were evaluated for their chemical composition by GC-MS. Results showed 17 predominant compounds for L. lucida, among which β-caryophyllene (19.0%) and α- caryophyllene (or humuleno, 33.0%) were the major components. L. salzmannii showed the presence of...
