A checklist of freshwater algae of the Northwest Territories, Canada. Can. J. Bot. 60: 1964- 1997. A checklist of the freshwater algae from the Northwest Territories has been compiled to add to an algal flora of Canada. The 44 studies included report on 279 bodies of water. A large diversity of algal communities has been examined in these investigations, such as phytoplankton and periphyton in permanent and temporary tundra ponds, polluted and unpolluted high arctic lakes, and subarctic lakes and streams. The flora consists of 212 genera and 1577 subgeneric taxa. The major algal classes represented in this list are the Bacillariophyceae (761 taxa), the Chlorophyceae (481 taxa), and the Cyanophyceae (173 taxa). Introduction and discussion This checklist (see Appendix) has been to extend the partial freshwater algal flora of Canada initiated by the publication of checklists from ontario (Duthie and Socha 1976) and ~ ~ i t columbia i ~ h (stein and Borden 1979). Such a flora will be useful as a baseline for future limnological studies, environmental impact assessments, and biogeographic and speciation analyses. The literature cited includes largely published works plus a few key unpublished governmental reports. Wherever possible, dated published taxonomic names have been reassigned using such references as Bourrelly (1968, 1970, 1972), Patrick and Reimer (1966, 1975), and Prescott et al. (1972, 1975, 1977, 1981). ~h~ Northwest ~ ~ ~occupies i the ~ largest ~ rsur- i face area of any province, state, or territory in ~~~h America (2 080 000 km2). hi^ complex geographic region includes boreal forest, alpine regions, marine and continental low arctic tundra, and high arctic areas (Burns 1973). The number of ponds and lakes estimated to occur in tundra regions ranges from hundreds of thousands to millions (Rawson 1953), covering 50% or more of the surface in some places (Mackay 1963). The 44 studies included in this checklist report on 279 bodies of water and hence only a tiny fraction of the freshwater habitats have been examined. However, these investigations have covered a wide diversity of communities, such as phytoplankton and periphyton in permanent and temporary tundra ponds, polluted and unpolluted high arctic lakes, and subarctic lakes and streams. ~h~ checklist contains 212 genera and 1577 subgeneric taxa. The major groups reported are the Bacillariophyceae (761 taxa or 48.3%), ~ h l (481~ taxa or ~ 30.5%), and Cyanophyceae (173 taxa or 11.0%). The minor classes include the Chrysophyceae (73 taxa), (26 taxa)' (21 Eugleno~h~ceae (I9 taxa)y X a n t h o ~ h ~ c e a(I4 e taxa), F1Orideophyceae (2 taxa), PrasinO~h~ceae (2 taxa), Pr~mnesiophYceae (1 taxon), Craspedophyceae (1 taxon), and Bangiophyceae (1 taxon). There are also two glaucophytes of uncertain taxonomic position. The major type of freshwater habitat in the N.W.T. is the tundra pond which is unique in terms of habitats contributing to a Canadian flora. Tundra ponds are less than 2 m in depth and freeze solid each winter, thereby preventing their habitation by fish (Hobbie 1980). The growing season is shortened to 3 or 4 months during time the photoperiod is altered to a prolonged light phase (PrescOtt 1963). The lack a dark period greatly inhibits sponlation gametogenesis in taxa requiring da~-length As a result$members of the Oedogoniales and Zygnematales have been form zygOspOresin tundra regions (PrescOtt 1963; Sheath et 1975). Lack of resistant-spore formation is critical in that cells must survive freezing for up to 9 months in the vegetative ~ ~ state. One might expect these environmental stresses to produce a unique northern algal composition. However, this checklist contains few endemics and the majority of species are widespread in temperate parts of the world. The predominance cOsmo~O1itan species is true of tundra ponds and lakes in ~ l a s k a the , flora of which coincides with that the N.W.T. an average of 62% (Hilliard 1959; Prescott and Vinyard 1965; ~ a l f 1967; f Alexander et al. 1980). The similarity between algal communities in northern and temperate regions may be The lowered frequency more apparent than sexual reproduction in the arctic combined with geographic separation tend to produce a small gene pool which may be genetically those in southern areas. Therefore, before definitive conclusions can be made regarding algal floristics in the N.W.T., it will be necessary for genetic comparisons to be ~made between ~ hclones ~isolated~ from several ~ ~locations ~ using such techniques as electrophoresis and immuneALEXANDER, V., D.
