When are your animals in each other’s vicinity?
For how long? And how often?

Conduct your interaction studies with our two-collar Proximity Sensor system, in which the Master collars sense the presence or absence of the SUB (‘Slave UHF Beacon’) collars. In this way, new animal interaction dynamics are revealed. This system is a cost-effective alternative for studying groups of any size.

A two-part system

Master Collar
Detects the presence or absence of SUB collars and relays this information to you remotely.master collar

  • IridiumTrackM (800 g – 1.2 kg)
  • WildCell GSM (500 g – 950 g)
  • Schedules may be altered remotely
  • Video camera option

SUB Collar
When the SUBs are within short range of the GPS Master, the SUB IDs are recorded by the Master collar.master collar

  • Weight 150 – 450 g
  • 1 – 3 years battery life
  • 65,000 unique IDs
  • 200 IDs in view of Master at a time

Types of interaction studies that can be conducted with Lotek Proximity Sensors include:

Conspecific interactions:

  • Fawn survival rates
  • Yearling adult separation time
  • Social status
  • Reproductive strategy
  • Herd coherence

Interspecies interactions:

  • Disease transmission (e.g., brucellosis, tuberculosis)
  • Competition for food resources

Predator-prey interactions:

  • Predation efficiency
  • Individual kill participation
  • Refractory period / chase details
