Quantitative fatty acid signature analysis: A new method of estimating predator diets
(2004-05)
Accurate estimates of the diets of predators are required in many areas of ecology, but for many
species current methods are imprecise, limited to the last meal, and often biased. The diversity of
fatty acids and their ...
Spectrally weighted transparency in models of water-column photosynthesis and photoinhibition by ultraviolet radiation
(2004)
We present a simple method for describing the influence of variable attenuation of spectral irradiance, Kd(lambda), on water-column photosynthesis and its inhibition by ultraviolet radiation (UV). The approach is based on ...
Demonstration of the deposition and modification of dietary fatty acids in pinniped blubber using radiolabelled precursors
(2004-07)
Radioisotopes are commonly used to study the in vivo metabolism and deposition of dietary fatty
acids in adipose tissue. The application of this approach to pinnipeds is problematic because of
their large mass and blubber ...
Synchronized hatch and its ecological significance in rainbow smelt Osmerus mordax in St. Mary's Bay, Newfoundland
(2004-11)
Early life history stages in most marine animals are subject to high mortality through
predation, starvation, and dispersal. Accordingly, the potential exists for the selection of
behavioral mechanisms that reduce ...
Mapping coastal optical and biogeochemical variability using an autonomous underwater vehicle and a new bio-optical inversion algorithm
(2004-08)
Autonomous underwater vehicles (AUVs) can map water conditions at high spatial ( horizontal and vertical) and temporal resolution, including under cloudy conditions when satellite and airborne remote sensing are not feasible. ...
Taking measure of the Andromeda halo: a kinematic analysis of the giant stream surrounding M31
(2004-06)
We present a spectroscopic survey of the giant stellar stream found in the halo of the Andromeda galaxy. Taken with the DEIMOS multi-object spectrograph on the Keck2 telescope, these data display a narrow velocity dispersion ...
