Resheff et al. (2024), How to treat mixed behavior segments in supervised machine learning of behavioural modes from inertial measurement data. Mov Ecol

The application of supervised machine learning methods to identify behavioural modes from inertial measurements of bio-loggers has become a standard tool in behavioural ecology…

Olive baboons: We used a dataset from 6 olive baboons that were collared with data loggers (e-Obs Digital Telemetry, Gruenwald, Germany) in August 2019 for a period of one month and videotaped during this period to match the acceleration records with known behaviours. Continuous triaxial accelerations were recorded…

Papageorgiou et al. (2024), Testing the information centre hypothesis in a multilevel society. _Journal of Animal Ecology

  1. In various animal species conspecifics aggregate at sleeping sites. Such aggregations can act as information centres where individuals acquire up-to-date knowledge about their environment. In some species, communal sleeping sites comprise individuals from multiple groups, where each group maintains stable membership over time.
  2. We used GPS tracking to simultaneously record group movement in a population of wild vulturine guineafowl (Acryllium vulturinum) to investigate whether communal sleeping sites can facilitate the transfer of information among individuals across distinct groups. These birds live in large and stable groups that move both together and apart, often forming communal roosts containing up to five groups.
  3. We first test whether roosts provide the opportunity for individuals to acquire information from members of other groups by examining the spatial organization at roosts. The GPS data reveal that groups intermix, thereby providing an opportunity for individuals to acquire out-group information.
  4. We next conduct a field experiment to test whether naïve groups can locate novel food patches when co-roosting with knowledgeable groups. We find that co-roosting substantially increases the chances for the members of a naïve group to discover a patch known to individuals from other groups at the shared roost. Further, we find that the discovery of food patches by naïve groups subsequently shapes their space use and inter-group associations. We also draw on our long-term tracking to provide examples that demonstrate natural cases where communal roosting has preceded large-scale multi-group collective movements that extend into areas beyond the groups’ normal ranges.
  5. Our findings support the extension of the information centre hypothesis to communal sleeping sites that consist of distinct social groups.
