The fishing (dock or wharf) spiders (Dolomedes spp. Latreille, 1804) of the Maritime Provinces of Canada were surveyed
through a combination of new collecting and examination of specimens from the Nova Scotia Museum and the New
Brunswick Museum. Four species (Dolomedes tenebrosus Hentz, 18...

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...

Provides an overview of insects and their close relatives. Coverage includes insect classification, behavior, ecology, genetics and evolution, physiology, and management, and references to relevant literature. All the major arthropod groups are addressed, along with many important families and speci...

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...

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...

Recent concerns about the spread of the mosquito-borne West Nile Virus (WNV) through North America
have prompted a number of regional studies of mosquito species composition and distribution. In this study, we report
on intensive surveys of mosquitoes on Prince Edward Island (PEI). Larvae ...

The importance of microhabitat variables to stream macroinvertebrates can be difficult to assess due to the large number and intercorrelation of relevant environmental variables. In this study, substrate, detritus, and hydraulic variables were evaluated in patches arranged in a grid across a run of ...

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...

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...
