Prevalence and predictability of handling effects on plants in field studies: Results from field experiments and a meta-analysis

Brown, M., Hik, D.S., Weir, J., Dabros, A., Cahill, J.F.
Various effects on plant growth associated with handling or touching plants are well documented from greenhouse and laboratory studies, but are generally unknown or ignored under field conditions. We examined the prevalence of the effects of handling, at levels typical of many ecological...

Variation in the temporal pattern of vulnerability can provide important insights into predator-prey relationships and the evolution of antipredator behavior. We illustrate these points with a system that has coyotes (Canis latrans) as a predator and two species of congeneric deer (Odocoileus...

The evolution of GnRH and the role of multiple forms within the brain are examined. Three forms of GnRH were purified from the brain of Pacific herring (Clupea harengus pallasi) and characterized using Edman degradation and mass spectrometry. Two forms correspond with the known structures of...

Somoza, G.M., Rivier, J.E., Fischer, W.H., Park, M.K., Chang, J.P., Craig, A.G., Montaner, A.D., Sherwood, N.M.
The neuropeptide GnRH is the major regulator of reproduction in vertebrates acting as a first signal from the hypothalamus to pituitary gonadotropes. Three GnRH molecular variants were detected in the brain of a fish, pejerrey (Odontesthes bonariensis), using chromatographic and immunological...

An unidentified environmental reservoir of infectivity contributes to the natural transmission of prion diseases (transmissible spongiform encephalopathies [TSEs]) in sheep, deer, and elk. Prion infectivity may enter soil environments via shedding from diseased animals and decomposition of...
