Variable measured
  • Variable name: Matrix of trophic relations among the species/taxa  Variable description: This dataset consists in a square matrix where all know predator-prey relationships are listed for bird and mammal species of Labrador and the province of Quebec north of 50°N, as well as for some groups of arthropods (arachnida, coleoptera, diptera, hymenoptera, lepidoptera) and plants (lichens, grasses, low shrubs, erect shrubs, mosses, cyperacea, poacea). In the matrix, 1 means that the species in the column is known to feed on the species/taxa in the row, whereas 0 indicates that no predator-prey relationship is known.  Variable unit: unitless
