Description

A data file with paired mortality estimates of humans and non-human predators on shared prey.

Usage

predPom

Format

A data frame with 99 rows and 22 variables:

CaseID: integer Indicates exploitation rates of a particular prey from the same study. Rows with the same CaseID represent exploitation rates by different predators from the same study.
Ecosystem: logical Indicates Marine or Terrestrial Ecosystem
SystemID: integer Indicates predator-prey interactions from the same ecosystem/location and the same study. In cases where studies provided data from more than one ecosystem, different system identifiers were provided.
Citation: character Publication from which exploitation rates were obtained
DataSource: character Page number and/or table from which exploitation rates were obtained within the original publication
StudyType: character The type of study (e.g., EwE ecosystem model, survivorship, etc)
PubYear: integer Year in which the study was published
Region: character Ocean for marine studies or continent for terrestrial studies
Lat: double Latitude of the study
NS: character North or South Hemisphere for Latitude
Long: double CLongitude of the study
EW: character East or West Hemisphere for longitude
SpeciesID: integer nique identifier for prey species (numeric)
Order: character Order of prey species
Family: character Family of prey species
Genus: character Genus of prey species
Species: character Prey species
Paired: character "P" indicates studies that have exploitation estimates for both humans and non-human predators, "U" indicates exploitation estimates that are unpaired (in this file all cases are paired, "P")
HumanPoM: double Proportion of mortality on a prey species attributed to humans
MaxPOM: double Maximum proportion of mortality; Proportion of mortality on a prey species attributed to the highest-exploiting non-human predator in a terrestrial system
CumPOM: double Cumulative proportion of mortality; Proportion of mortality on a prey species attributed to all non-human predators in a terrestrial system
NPredPOM: integer Number of non-human predators in the system
