  • African elephants can detect water from natural and artificial sources via olfactory cues 
    Wood, Matthew; Chamaillé-Jammes, Simon; Hammerbacher, Almuth; Shrader, A.M. (Adrian) (Springer, 2022-02)
    Water is vital for mammals. Yet, as ephemeral sources can be difficult to find, it raises the question, how do mammals locate water? Elephants (Loxodonta africana) are water-dependent herbivores that possess exceptional ...
  • Alarm calls or predator calls : which elicit stronger responses in ungulate communities living with and without lions? 
    Makin, Douglas F.; Chamaillé-Jammes, Simon; Shrader, A.M. (Adrian) (Springer, 2019-05)
    Alarm calls and predator vocalizations convey information on predator presence and potential risk. Generally, prey employ anti-predator behaviours more in response to alarm calls. However, occasionally prey respond more ...

    In semi-arid savannas, the availability of surface water constrains movements and space-use of wild animals. To accurately model their movements in relation to water selection at a landscape scale, innovative methods have ...
  • Cueing on distant conditions before migrating does not prevent false starts : a case study with African elephants 
    Pandraud, Anne; Shrader, A.M. (Adrian); Tshipa, Arnold; Ngwenya, Nobesuthu; Chamaillé-Jammes, Simon (Springer, 2022-04)
    Migratory animals often use environmental cues to time their seasonal migrations. Local conditions may, however, differ from distant ones, and current conditions may poorly predict future conditions. This may be particularly ...
  • Disentangling the roles of bottom-up and top-down drivers in the trade-off between food acquisition and safety in prey with multiple predators 
    Pays, Olivier; Blanchard, Pierrick; Chamaillé-Jammes, Simon; Valeix, Marion; Loveridge, Andrew J.; Macdonald, David W.; Periquet, Stephanie; Van der Meer, Esther; Duncan, Patrick; Mtare, Godfrey; Fritz, Herve (Wiley, 2021-02)
    Prey face a trade-off between acquiring food and avoiding predation, but food availability, and therefore its effect, is rarely measured in field studies investigating non-lethal effects of predation. The main aim of this ...
  • Do infanticides occur in harem-forming equids? A test with long-term sociodemographic data in wild plains zebras 
    Vitet, Camille; Duncan, Patrick; Ganswindt, Andre; Mabika, Cheryl; Chamaillé-Jammes, Simon (Elsevier, 2021-07)
    Social dynamics can play a major role in shaping the population ecology and evolutionary trajectory of a species. This is, for instance, the case in species known to experience infanticide when a dominant male is replaced ...
