BadgerActivity: Longitudinal badger activity data

In romunov/AED: Package Accompanying 'Mixed Effects Models and Extensions in Ecology with R'

Description

Longitudinal badger activity data from several farms from 2003-2005.

Usage

data("BadgerActivity")

Details

Longitudinal data of badger (Meles meles) activity from 36 farms in eight consecutive occassions from 2003 to 2005. All farms were located in South-West England, known for its high badger activity. Badgers are known to be a a vector for spreading tuberculosis which is why humans (Homo sapiens) have a keen interest in studying them as they can have public health and economic impact on humans and livestock.

Some of the original variable names have been renamed (i.e. Year -> year) for consistency. Variables in the dataset are:

• year: Calendar year

• season: Spring (Mar-May), summer (Jun-Aug), autumn (Sept-Nov), winter (Dec-Feb)

• farm_code: Blinded farm identifier

• survey: Which of the eight survey occasions (i.e. the time indicator)

• signs_in_yard: Binary indicator of signs of badger activity

• latrines_with_farm_feed: Binary indicator - do (any) observated badger latrines contain farm feed? This is proxy for the fact that badgers must have been on the farm.

• no_latrines_with_farm_feed: The number of the above

• no_scats_with_farm_feed: Number of badger scats identified as containing farm feed

• no_latrines: Number of badger latrines observed

• no_setts_in_fields: Number of badger setts (i.e. homes) observed

• no_active_setts_in_field: Number of actively used setts observed

• no_buildings: Number of buildings on farm

• no_cattle_in_buildings_yard: Number of cattle housed in the building yard

• mode_feed_store_accessibility: Quantitative index of how easy it would be for badgers to access farm's feed store

• accessible_feed_store_present: Binary indicator - is such a feed store present?

• mode_cattle_house_accessibility: Quantitative indicator of how easy it would be for badgers to access the cattle house

• accessible_cattle_house_present: Binary indicator - is cattle house present?

• accessible_feed_present: Binary indicator - is accessible food present?

• grass_silage: Binary indicator of presence of grass silage

• cereal_silage: Binary indicator of presence of cereal silage

• hay_straw: Binary indicator of presence of hay or straw

• cereal_grains: Binary indicator of presence of cereal grains

• concentrates: Binary indicator of presence of concentrates

• protein_blocks: Binary indicator of presence of protein blocks

• sugar_beet: Binary indicator of presence of sugar beet

• vegetables: Binary indicator of presence of vegetables

• molasses: Binary indicator of presence of molasses
