Ergopeptine Alkaloids in Grazed Tall Fescue
Endophyte (Acremonium cotnophiaJum Morgan-Jones et Gams) -Infected tall fescue (Festuca arundinacea Schreb.) produces ergopeptiDe alkaloids (EP) that may be associated with fescue toxicosis symptoms in cattle (B03 taurus). A study was conducted during 1983 and 1984 at Watkinsville, GA, to determine the effects of endophyte infection, season, and N fertilization on EP concentration and Steer ave...
متن کاملPostgraze assessment of toxicosis symptoms for steers grazed on toxic endophyte-infected tall fescue pasture.
A 2-yr pen experiment was conducted using 12 different crossbred Angus steers each year to determine if short-term changes in prolactin concentrations, body temperature, and vasoconstriction reflect recovery from fescue toxicosis after steers that previously grazed toxic endophyte (Neotyphodium coenophialum)-infected Kentucky 31 tall fescue [Lolium arundinaceum (Schreb.) Darbysh] are placed on ...
متن کاملCurved Surface Patches for Rough Terrain Perception
Attaining animal-like legged locomotion on rough outdoor terrain with sparse foothold affordances — a primary use-case for legs vs other forms of locomotion — is a largely open problem. New advancements in control and perception have enabled bipeds to walk on flat and uneven indoor environments. But tasks that require reliable contact with unstructured world surfaces, for example walking on nat...

متن کاملExpanded view of ecosystem stability: A grazed grassland case study
Analysis of stability under linearized dynamics is central to ecology. We highlight two key limitations of the widely used traditional analysis. First, we note that while stability at fixed points is often the focus, ecological systems may spend less time near fixed points, and more time responding to stochastic environmental forcing by exhibiting wide zero-mean fluctuations about those states....
