Aquatic fungal colonization dynamics and seasonal patterns were investigated in two sites in Catamaran Brook, New Brunswick, Canada, as part of a larger study to evaluate logging effects on a salmon stream. Four leaf-pack trials were conducted between May 1995 and Dec 1996 to determine species compo...

In early July 1991, 234 pitcher plants (Sarracenia pulpurea) were transplanted from a Prince Edward Island bog being mined for peat into three bogs that varied with respect to previous pitcher plant abundance. One bog had a thriving natural pitcher plant population prior to transplant, while the oth...

Surveys of benthic invertebrates in subarctic Southern Indian Lake, Manitoba, before and after manipulation of the lake for hydroelectric development, revealed that Hexagenia (Insecta: Ephemeroptera) populations collapsed following the diversion phase. Initial conclusions attributed the collapse to ...

High levels of azinphos-methyl (0.4–0.8 μg/L) were detected in the Wilmot River, Prince Edward Island, Canada, following runoff from an agricultural field after a heavy rainfall on 19 July 2002. Benthic macroinvertebrate abundance and diversity were sharply lower in samples collected 1 d after th...

High levels of azinphos-methyl (0.4-0.8 mu g/L) were detected in the Wilmot River, Prince Edward Island, Canada, following runoff from an agricultural field after a heavy rainfall on 19 July 2002. Benthic macroinvertebrate abundance and diversity were sharply lower in samples collected 1 d after the...

Hexagenia limbata (Serville) and H. rigida McDunnough from Southern Indian Lake, Manitoba, were reared at 10-degrees, 15-degrees, and 20-degrees-C to assess temperature effects on growth. Subsequently, H. limbata was reared at two food levels and two or three nymphal densities (depending on size cla...

Egg development was investigated for Hexagenia limbata (Serville) from Southern Indian Lake (SIL) in northern Manitoba, Canada. The SIL population is located near the northern range limit of H. limbata, and some important differences in hatching dynamics were seen in comparison with southern populat...
