Microsatellite and allozyme analyses reveal few genetic differences among spatially distinct aggregations of geoduck clams (Panopea abrupta, Conrad 1849)
(2004-12)
The genetic population structure of geoduck clams (Panopea abrupta) in inland waters of
Washington may affect fishery management and aquacultural practices involving this species. To
investigate genetic differentiation ...
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 ...
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 ...
Two centuries of multiple human impacts and successive changes in a North Atlantic food web
(2004-10)
European colonization of North America, severely altered terrestrial and aquatic ecosystems alike. Here, we integrate archaeological, historical, and recent data to derive the ecological history of the Quoddy Region, Bay ...
Pollen limitation of plant reproduction: Ecological and evolutionary causes and consequences
(2004-09)
Determining whether seed production is pollen limited has been an area of intensive empirical study over the last two decades. Yet current evidence does not allow satisfactory assessment of the causes or consequences of ...
