Table 1 Study eligibility criteria

From: What are the effects of climate variability and change on ungulate life-histories, population dynamics, and migration in North America? A systematic map protocol

PECO component Include Exclude
Population: Pronghorn, elk, mule deer, moose, bighorn sheep, white-tailed deer, American bison, mountain goat, Dall sheep, muskox, caribou, collared peccaries, white-lipped peccaries, brown brocket deer, and red brocket deer in North America Articles on any wild population of native ungulates in North America 1) Articles on populations of ungulates located outside of North America (e.g. moose in northern Europe)
2) Articles on domestic or non-native populations of ungulates
Exposure:
1. Direct climate variables (temperature, precipitation) and their derivatives
2. Secondary variables (plant phenology, wildfire, invasive species, disease, predation)
1) Articles on the effects of temporal changes in direct climate variables on ungulates in North America
2) Articles on the effects of temporal changes in secondary variables on ungulates, if the changes in secondary variables are linked to changes in a direct climate variable
1) Articles that describe space-for-time time comparisons and do not describe a temporal change in variables
2) Articles exploring the effects of changes in secondary variables on ungulates, but do not link those changes in secondary variables to changes in a direct climate variable
Comparator: A comparison of at least two different time points, over which there is a quantified, inferred, or projected change in a direct climate or secondary variable Articles that use empirical analyses or projections to describe (1) the effects of temporal changes in direct climate variables on ungulates, or (2) the effects of climate-related changes in secondary variables on ungulates Articles that only use data from a single point in time or those that do not specify the temporal scale of the study
Outcome: Life-history characteristics; population dynamics; migratory behavior; spatial location or quality of migration corridor, winter range, or summer range habitat Articles that document (1) the effects of changes in direct climate variables or (2) the effects of climate-related changes in secondary variables on any aspect of ungulate life-history characteristics, population dynamics, migration, or range habitats in North America
