Historical Biogeography Of The North American Glacier Ice Worm, Mesenchytraeus Solifugus (annelida: Oligochaeta: Enchytraeidae)
North American ice worms are the largest glacially-obligate metazoans, inhabiting coastal, temperate glaciers between southcentral Alaska and Oregon. We have collected ice worm specimens from 10 new populations, completing a broad survey throughout their geographic range. Phylogenetic analyses of 87...
