The number of collared adult females is 'topped up' at each month_collar. Survival rates in each month/year determine the number of mortalities. The probability of uncertain mortality determines the proportion of mortalities that are uncertain. The probability of uncertain survival reduces the number of collared adult females without adding mortalities.

Arguments

collared_adult_females

A whole positive number of the number of collared adult females. The number of collared adult females is 'topped up' each year at month_collar.

survival_adult_female_month_year

A matrix of the female adult survival rates with dimensions month and year.

probability_uncertain_mortality

A number between 0 and 1 of the probability of uncertain mortality.

probability_uncertain_survival

A number between 0 and 1 of the probability of uncertain survival.

month_collar

A whole number between 1 and 12 of the collaring month.

population_name

A string of the population name. This does not affect simulation but can be used as a unique identifier.

Value

A data.frame of the number of collared adult females, certain mortalities and uncertain mortalities in each year and month.

Examples

survival <- bbs_survival_caribou(0.84)
survival_adult_female <- survival$eSurvival[, , 3]
survival_collared <- bbs_survival_collared(
  collared_adult_females = 30,
  survival_adult_female_month_year = survival_adult_female
