Utheria

Ranging behaviour

Units

Miners should be particularly careful with the choice of units in this list and note that some units are lengths, whilst others are areas. Choose one of:
• square metres
• hectares
• square kilometres
• acres
• square miles
• metres — for linear ranges.
• kilometres — for linear ranges.
• miles — for linear ranges.

Range Type
Choose one of:
• Territory size — size of the area actively defended by individuals or groups.
• Home Range — size of the area within which everyday activities of individuals or groups are typically restricted.
• Day Range — linear distance typically traversed by individuals or groups in a 24-hour cycle

Estimation Method
Choose one of:
• Unspecified
• Trapping — capture of live animals.
• Radio telemetry — tracking movements of animals fitted with radio transmitting device. This category also covers GPS tracking methods.
• Direct observations — direct recordings of individual animals by field observers.

Study Start Date
Use this field to record the start date of the study. The start date should be recorded as precisely as possible but if only month or season are reported then record this information in the Study Start Date field. The miner should also enter data on study duration and effort.

The miner must also record whether the range is individual or group range. If the data is for a group range then the record the group size and select the Group Type from the following list:

• Social group — individuals that spend the majority of their time in a 24 hour cycle together where there is some indication that these individuals form a social cohesive unit, unlike the esamples given above. In most instance, this will be social group size will be the same as population group size.
• Population group — individuals that spend the majority of their time in a 24 hour cycle together. This includes all data on aggregations, including loose aggregations of
individuals such as bat roosting groups, ungulate migration groups, carnivore/ungulate hauling out groups and bat mating swarms.
• Parental care group — individuals grouping for the purposes of care of infants during the period of primary dependency.
• Mating group — aggregation of individuals for the purposes of reproduction, including size of harem groups, mating swarms and leks.
• Hunting group — individuals actively cooperatively hunting for food.
• Feeding group — individuals gathering to feed (e.g. grazing herds of ungulates, primates around a fruit tree, carnivores gathering around a kill)
