Phylogenetic and ecological relationship between "giant" pygmy whitefish (Prosopium spp.) and pygmy whitefish ( Prosopium coulteri) in North-Central British Columbia.

We developed seven polymerase chain reaction (PCR) based markers that detect genetic variation at loci related to growth (four) and immune function (three) in chinook salmon. One assay shows a length polymorphism following PCR; the others show restriction fragment length polymorphisms (PCR‐RFLP). Two alleles were detected in each assay, and the common alleles were found at frequencies of 0.67–0.95 in seven wild populations in British Columbia, Canada. These loci also amplified in other salmonid species. These markers, by detecting variation linked to genes with high fitness relevance, are expected to be useful in a range of theoretical and applied studies.

“…Pygmy whitefish Prosopium coulterii is a nonanadromous species with a strikingly disjunct distribution in north-central and northwestern North America ( Fig. 6A; Eigenmann and Eigenmann, 1892;Myers, 1932;Wynne-Edwards, 1947;Eschmeyer and Bailey, 1955;Heard and Hartman, 1966;McCart, 1970;Lindsey and Franzin, 1972;Weisel et al, 1973;Poe et al, 1976;Bird and Roberson, 1979;Russell, 1980;Buell, 1991;Chereshnev and Skopets, 1992;Lonzarich, 1992;Mayhood, 1992;Hallock and Mongillo, 1998;Nelson and Shelast, 1998;Mathisen and Sands, 1999;Mackay, 2000;Rankin, 2004;Plumb, 2006;Zemlak and McPhail, 2006;Froese and Pauly, 2009). Pygmy whitefish typically inhabit cold, deep lakes and glacially fed rivers, most within the footprint of the Laurentide and Cordilleran ice sheets, and morphological variations among populations have been used to infer locations of Pleistocene freshwater refugia (e.g., Lindsey and Franzin, 1972).…”

Late Quaternary megafloods from Glacial Lake Atna, Southcentral Alaska, U.S.A.

Geomorphic, stratigraphic, geotechnical, and biogeographic evidence indicate that failure of a Pleistocene ice dam between 15.5 and 26 ka generated a megaflood from Glacial Lake Atna down the Matanuska Valley. While it has long been recognized that Lake Atna occupied ⩾9000 km2 of south-central Alaska's Copper River Basin, little attention has focused on the lake's discharge locations and behaviors. Digital elevation model and geomorphic analyses suggest that progressive lowering of the lake level by decanting over spillways exposed during glacial retreat led to sequential discharges down the Matanuska, Susitna, Tok, and Copper river valleys. Lake Atna's size, ∽50 ka duration, and sequential connection to four major drainages likely made it a regionally important late Pleistocene freshwater refugium. We estimate a catastrophic Matanuska megaflood would have released 500–1400 km3 at a maximum rate of ⩾3×106 m3 s–1. Volumes for the other outlets ranged from 200 to 2600 km3 and estimated maximum discharges ranged from 0.8 to 11.3×106 m3 s–1, making Lake Atna a serial generator of some of the largest known freshwater megafloods.
