Energy-efficient computing for wildlife tracking: design tradeoffs and early experiences with ZebraNet

The goal is to use the least energy, storage, and other resources necessary to maintain a reliable system with a very high `data homing' success rate and it is believed that the domain-centric protocols and energy tradeoffs presented here for ZebraNet will have general applicability in other wireless and sensor applications.

Role assessment, reserve strategy, and acquisition of information in asymmetric animal conflicts
It was formerly argued that alternative evolutionarily stable strategies (ESSs) are possible for animal contests characterized by some asymmetry that can be perceived with perfect accuracy. Where…
Mortality risk of spatial positions in animal groups: The danger of being in the front
We modified Hamilton's (1971) selfish herd model by introducing directional movement to the prey groups and the predators. The consequences of this modification with regards to differential predation…
Social relationships and reproductive state influence leadership roles in movements of plains zebra, Equus burchellii

In animal groups, collective movements emerge from individual interactions. Biologists seek to identify how characteristics of actors in these groups, and their relationships, influence the…
The Dynamics of Herds: From Individuals to Aggregations
Abstract The dynamic behavior of small herds is investigated by means of simulations of two-dimensional discrete-stochastic models. An individual-based approach is used to relate collective behavior…
Network metrics reveal differences in social organization between two fission–fusion species, Grevy’s zebra and onager

The current approach demonstrates the utility of network metrics for identifying fine-grained variation among individuals and populations in association patterns and can make testable predictions about behavioral mechanisms underlying social structure and its effects on transmission processes.
DNA metabarcoding illuminates dietary niche partitioning by African large herbivores

DNA metabarcoding was used to quantify diet breadth, composition, and overlap for seven abundant LMH species (six wild, one domestic) in semiarid African savanna, suggesting that LMH diversity may be more tightly linked to plant diversity than is currently recognized.
Leadership in fish shoals
Leadership is not an inherent quality of animal groups that show directional locomotion. However, there are other factors that may be responsible for the occurrence of leadership in fish shoals, such…
Moving in the Anthropocene: Global reductions in terrestrial mammalian movements
Using a unique GPS-tracking database of 803 individuals across 57 species, it is found that movements of mammals in areas with a comparatively high human footprint were on average one-half to one-third the extent of their movements in area with a low human footprint.
