Whiskered Auklets Aethia Pygmaea, Foxes, Humans and How to Right a Wrong

چکیده
Whiskered Auklets Aethia pygmaea are relatively rare alcids, currently distributed on select islands within the Aleutian, Commander, and Kurile island chains of the North Pacific to which they are endemic (Fig. 1; Byrd & Williams 1993, Gaston & Jones 1998). Whiskered Auklets forage in tiderips, swirls, and tidal pumps or fronts on zooplankton that is concentrated near islands and offshore reefs by strong upwelling (Byrd & Gibson 1980, Byrd & Williams 1993, Gaston & Jones 1998). These foraging areas are persistent in space and time and largely do not depend on the season (Zubakin & Konyukhov 2001). Because of this, Whiskered Auklets are mostly non-migratory, unlike other Aethia species, and are found year-round within 16 km of shore (Byrd & Gibson 1980). This nearshore marine foraging habitat is common throughout the Aleutian and Kurile islands, and is the primary factor regulating the distribution and abundance of Whiskered Auklets (Zubakin & Konyukhov 2001).

Toward sustainable ecosystem services from the Aleutian Archipelago
The new research reported in this special issue of Fisheries Oceanography expands our understanding of the Aleutian Archipelago ecosystem. Yet our knowledge remains very limited, while the use of this ecosystem for commercial activities, recreation and other purposes expands. Given this situation, how can we sustain the ecosystem services (food, fuel, fibers as well as spiritual, recreational, ...
متن کاملA test of founder effect speciation using multiple loci in the auklets (Aethia spp.).
Whether speciation results more frequently from the genetic consequences of founder events or from gradual genetic divergence of large populations is a matter of debate. In this study, multiple analyses were applied to data from three loci (cytochrome b, alpha-enolase intron VIII, and MHC class II B) to test for founder effects associated with speciation in Aethia (Aves: Alcidae), a genus of se...
متن کاملAvian plumage ornaments are some of the best-studied sexually selected traits in animals. From the elongated tails of long-tailed widowbirds Euplectes progne (Andersson, 1982) to the ornate forehead crests of crested auklets Aethia cristatella
sexually selected traits in animals. From the elongated tails of long-tailed widowbirds Euplectes progne (Andersson, 1982) to the ornate forehead crests of crested auklets Aethia cristatella (Jones et al., 2000), particular attention has been paid to understanding the types of information that birds communicate with these extravagant displays. The bright plumage colors of male birds have emerge...
متن کاملWorking through polytomies: auklets revisited.
Polytomies, or phylogenetic "bushes", are the result of a series of internodes occurring in a short period of evolutionary time (which can result in data that do not contain enough information), or data that have too much homoplasy to resolve a bifurcating branching pattern. In this study we used the Aethia auklet polytomy to explore the effectiveness of different methods for resolving polytomi...
متن کاملAssessing the Effects of Introduced Norway Rats (rattus Norvegicus) on Survival and Productivity of Least Auklets (aethia Pusilla)
A .—We assessed potential eff ects of introduced Norway rats (Ra us norvegicus) on Least Auklets (Aethia pusilla) breeding at Sirius Point on Kiska Island, the largest auklet colony in the Aleutian Islands, Alaska. We compared productivity, chick growth, and adult survival of Least Auklets during 2001–2003 at Kiska and two nearby, rat-free Least Auklet colonies on Buldir and Kasatochi islands. ...
