Chironomidae (Diptera) of peatlands in northwestern Ontario, Canada
Characteristic features of the chironomid fauna of peatlands at ELA are discussed, the general applicability of these features to peatland, and needs for further research in these neglected but extensive Canadian habitats are considered.
Species diversity and emergence patterns of nematocerous flies (Insecta: Diptera) from three coastal salt marshes in prince Edward Island, Canada
Emerging insects were monitored every 10 days between early May and late August 1993, from tidal pools in three coastal salt marshes on Prince Edward Island, Canada, and overall patterns were highly variable, depending upon species.
Sampling Emerging Chironomidae (Diptera) with Submerged Funnel Traps in a New Northern Canadian Reservoir, Southern Indian Lake, Manitoba
We examined sampling characteristics of submerged funnel traps which were used to study emergence of Chironomidae in a large boreal riverine reservoir. Clay, bedrock, and marsh shorelines were…
Water mites from Canada, with description of a new species, Atractides (Atractides) ontarioensis (Acari: Hygrobatidae)
A new species, Atractides (Atractides) ontarioensis, is described from the Experimental Lakes Area, near Kenora as well as from lakes in the Dorset region.
Chironomidae (Diptera) Emerging from the Littoral Zone of Reservoirs, with Special Reference to Southern Indian Lake, Manitoba
The adult chironomid fauna of the littoral zone of Southern Indian Lake (SIL) was compared with that of other similar reservoir studies. A total of 158 species of adult Chironomidae were collected…
Descriptions and ecological notes on seven new species of Cladotanytarsus (Chironomidae: Diptera) collected from an experimentally acidified lake
The pupal diagnosis to Cladotanytarsus has been revised to accommodate the 21 Holarctic species included in a pupal key and the phenologies, depth distributions, and effects of pH changes on the tolerance ranges of the seven new species.

Experimental acidification of a poor fen in northwestern Ontario: effects on emergence of Chironomidae (Diptera)
Stability of species composition, despite experimental treatments and physiographic differences in the fen, may be a widespread characteristic of Canadian acidic peatlands.

The experimental flooding of Lake (L) 979, a small wetland lake at the Experimental Lakes Area (ELA) in northwestern Ontario, provided an opportunity to study effects on the chironomid fauna emerging from the surrounding peatland, which changed dramatically and added another 18 species to the 37 peat land species already identified from previous studies at the ELA.
Atractides (Octomegapus) elaensis, a new species of water mite from western Ontario (Acari: Hydrachnellae: Hygrobatidae)
ABSTRACT Atractides (Octomegapus) elaensis Conroy and Bilyj n.sp. is described from Lake 239 in the Experimental Lakes Area, near Kenora, Ontario. This represents the first record of a member of the…
