Goal-dependent current compensation and drift in surf scoter flocks
BACKGROUND Animals moving through air or water toward a goal frequently must contend with fluid currents, which can drift the actual path of the animal away from the direction of heading. Whether, and to what degree, animals compensate for currents depends on the species and environmental context, but plays an important role in the movement ecology of the species. In this paper, flocks of surf ...
متن کاملComposition, Shell Strength, and Metabolizable Energy of Mulinia lateralis and Ischadium recurvum as Food for Wintering Surf Scoters (Melanitta perspicillata)
Decline in surf scoter (Melanitta perspicillata) waterfowl populations wintering in the Chesapeake Bay has been associated with changes in the availability of benthic bivalves. The Bay has become more eutrophic, causing changes in the benthos available to surf scoters. The subsequent decline in oyster beds (Crassostrea virginica) has reduced the hard substrate needed by the hooked mussel (Ischa...

متن کاملSpeeding up SURF Imaging
Any good medical ultrasound imaging system must be able to resolve anatomical structures properly, and simultaneously provide adequate frame rate so that moving structures can be studied with ease. In a conventional imaging system these properties are related by a trade-off, but is it possible to have one and the other by applying more advanced post-processing to acquired RF data? Two new metho...
متن کاملThe surf is up
