English and American Wildlife Law: Lessons From the Past

1993 Proc. Annu. Conf. SEAFWA
Other laws also gave particular attention to breeding animals: gathering the eggs of birds
was prohibited in 1533 and in 1710, salmon were protected during their spawning runs, so
that they might "become very plentiful and common . . . as they were formerly" (Lund 1980).
Physical changes in animals' defensive abilities were also the occasion for English regulations.
In 1533 birds were protected when "the said old fowl be moulted, and not replenished with

Phylogeny and Evolutionary Ecology of Modern Sea ducks Anatidae: Mergini

The Condor 97:233-255 The Cooper Ornithological Society 1995
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

Curious Lives of Sea Ducks

Eleven out of 15 species of sea ducks appear to have declining populations within some portion of their range (exceptions are common goldeneyes, buffleheads, red-breasted mergansers and common mergansers). Furthermore, two species (Steller's eider and spectacled eider) are listed as threatened. Thus, waterfowl managers need current, science-based models to establish sustainable harvest strategies for sea ducks, and they need it now.

Wind Power, Wildlife and the Migratory Bird Treaty Act: A Way Forward

The “challenges facing wind energy remain both substantial and complex.Wildlife impacts
serve as one such obstacle for the wind industry, and as wind power expands in the United
States, so too do concerns about the impact of wind farms on avian and bat species.
In Part II we discuss anthropogenic effects on avian and bat species with particular emphasis
on wind turbines. In Part III, we provide a broad overview of the U.S. wildlife laws most pertinent

Behaviour and Ecology of Sea Ducks

Sea Ducks have been marginalized in Waterfowl conservation and management programs as most attention has been focused on the "sport ducks" notably mallards. In fact much of our understanding of the demography and harvest of ducks is based on the mallard model. Preceived lack of interest in the Sea Ducks had led to liberal management of this group. Large harvests in Southern areas and intense subsistence use in the North have proved a dangerous combination.
