Geography

Country: Canada

State: Nunavut

Coordinate: 67° 14' N, 100° 15' W

Coordinate basis: stated in text

Geography comments: "at Karrak Lake... and surrounding areas in the Queen Maud Gulf Bird Sanctuary"

•

Environment

Habitat: tundra

Protection: unprotected

Substrate: ground surface

Habitat comments: "gently rolling tundra"

Methods

Life forms: rodents

Sites: 4

Sampling methods: line transect,baited,snap traps

Sample size: 41 individuals

Years: 2000 - 2004

Days: 10

Seasons: summer

Nets or traps: 300

Net or trap nights: 3000

Sampling comments: sampling was "from July 2000 to July 2004... in two 1 km x 1 km study areas in the goose colony at Karrak Lake and in two 1 km x 1 km study areas outside the colony" and sampling was only in "early to mid-July" each year
there were "three traplines" in each area and "Each trapline consisted of 25 trap-stations, spaced 10 m apart, and with one snap-trap within 1 m of each trap station... Traplines were set for two consecutive nights" and "baited with a mixture of peanut butter and rolled oats"; there was a total of "2744.5 trap-nights" because the authors "subtracted 0.5 trap-nights for each trap that was snapped without capture", so the actual total seems to have been 10 x 300 = 3000 trap-nights
