Objective: To assess the nutritional quality of lunchtime food consumption among
elementary-school children on Prince Edward Island according to the source of
food consumed (home v. school).
Design: Students completed a lunchtime food record during an in-class survey.
Dietary ade...

We examined the life history and production of the Ephemeroptera, Plecoptera, and Trichoptera (EPT) community along a 500-m stretch of a hydrologically stable cold springbrook in Prince Edward Island during 1997 and 1998. Six mayfly species (Ephemeroptera), 6 stonefly species (Plecoptera), and 11 ca...

Mature nymphs of Pteronarcys biloba collected from Catamaran Brook, New Brunswick, between October 1994 and October 1995, were hosts to high numbers of parasitic chironomid larvae [Nanocladius (Plecopteracoluthus) undescribed sp., nr, branchicolus]. Nanocladius (P.) sp. has a univoltine life cycle i...

1. Life history patterns and production of eight shredder-detritivore species were studied in relation to the detritus dynamics of a small acidic stream in England. Mean annual detritus inputs (direct and lateral sources combined) were approximately 400 g m(-2) year(-1) and showed significant season...

Nymphs of Pteronarcys biloba Newman and attached chironomid larvae (Nanocladius [Plecopteracoluthus] undescribed sp, nr. branchicolus) were collected from Catamaran Brook, New Brunswick, in May and November 1997 for stable-carbon- and stable-nitrogen-isotope analysis. Nanocladius (P.) sp. had mean (...

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...

Mayflies (Ephemeroptera) were collected from 35 sites (streams and tundra ponds) across southern Nunavut in 2002-2005. Nine mayfly species were previously reported for Nunavut: Acentrella feropagus Alba-Tercedor and McCafferty, Acerpenna pygmaea (Hagen), Baetis bundyae Lehmkuhl, B. flavistriga McDun...

Predaceous water beetles were collected during expeditions along two northern Canadian rivers during 2000 and 2002. Twelve species of Dytiscidae (including 11 named species and one additional genus identified from a larva) and one species of Gyrinidae are recorded from 20 sites along the Horton and ...

Aim To understand factors that facilitate insular colonization by black flies, we tested six hypotheses related to life-history traits, phylogeny, symbiotes, island area, and distance from source areas. Location Four northern islands, all within 150 km of the North American mainland, were included i...
