Movement of foraging Tundra Swans explained by spatial pattern in cryptic food densities.
We tested whether Tundra Swans use information on the spatial distribution of cryptic food items (below ground Sago pondweed tubers) to shape their movement paths. In a continuous environment, swans create their own food patches by digging craters, which they exploit in several feeding bouts. Series of short (<1 m) intra-patch movements alternate with longer inter-patch movements (>1 m). Tuber ...
متن کاملHampered Foraging and Migratory Performance in Swans Infected with Low-Pathogenic Avian Influenza A Virus
It is increasingly acknowledged that migratory birds, notably waterfowl, play a critical role in the maintenance and spread of influenza A viruses. In order to elucidate the epidemiology of influenza A viruses in their natural hosts, a better understanding of the pathological effects in these hosts is required. Here we report on the feeding and migratory performance of wild migratory Bewick's s...
متن کاملYield of Black Swans
h EXCEPT FOR GETTING your chip to market on time, optimizing yield is perhaps the most important thing we can do to improve IC profitability. We address this problem in several ways: design for manufacturability (DFM) through layout rules, process control, and increasingly clean cleanrooms. In an ideal world, this would solve our yield problems. We know it doesn’t, so we build a diagnostic capa...
متن کاملIn Situ Analyses of Methane Oxidation Associated with the Roots and Rhizomes of a Bur Reed, Sparganium eurycarpum, in a Maine Wetland.
Methane oxidation associated with the belowground tissues of a common aquatic macrophyte, the burweed Sparganium eurycarpum, was assayed in situ by a chamber technique with acetylene or methyl fluoride as a methanotrophic inhibitor at a headspace concentration of 3 to 4%. Acetylene and methyl fluoride inhibited both methane oxidation and peat methanogenesis. However, inhibition of methanogenesi...
