Implications of Demographic Uncertainty for Harvest Management of North American Sea Ducks

In 2010, the Sea Duck Joint Venture (SDJV) identified the need for improved science support for harvest and habitat management of North American sea ducks.
In order to prioritize monitoring and research needs in support of harvest management, we applied a Prescribed Take Level (PTL) framework to assess the influence of uncertainty about sea duck demographic
parameters on comparisons of observed and allowable harvest estimates. We focused on 7 populations of North American sea ducks: the American subspecies of common eider (Somateria mollissima dresseri

Sea Duck Joint Venture Strategic Communications Plan 2015-2019

The mission of the Sea Duck Joint Venture(SDJV)is to promote the conservation of North American sea ducks through partnerships by providing greater knowledge
and understanding for effective management. SDJV focuses on the 15 species of North American sea ducks on their coastal water habitat for migration and wintering as well as boreal forest and tundra habitat for nesting. Since the JV’s founding in 1998, the four pillars of its work have included science, communications, funding, and conservation.

Abstract. Phylogenetic relationships of modem seaducks (Me&i) were investigated
using a cladistic analysis of 137 morphological characters. The analysis produced a single
tree (consistency index = 0.692, excluding autapomorphies) with complete resolution of the
relationships among the 25 taxa recognized. Phylogenetic inferences include: (1) the eiders
(Polysticta and Somateria) constitute a monophyletic group and are the sister-group of other
