  • Call order within vocal sequences of meerkats contains temporary contextual and individual information 
    Rauber, Ramona; Kranstauber, Bart; Manser, Marta B. (BioMed Central, 2020-09)
    BACKGROUND: The ability to recombine smaller units to produce infinite structures of higher-order phrases is unique to human language, yet evidence of animals to combine multiple acoustic units into meaningful ...
  • Collective close calling mediates group cohesion in foraging meerkats via spatially determined differences in call rates 
    Engesser Sabrina; Manser, Marta B. (Elsevier, 2022-03)
    During group movements, many socially living and group-foraging animals produce contact calls. Contact calls typically function to coordinate and maintain cohesion among group members by providing receivers with information ...
  • Cost of dispersal in a social mammal : body mass loss and increased stress 
    Maag, Nino; Cozzi, Gabriele; Bateman, Andrew; Heistermann, Michael; Ganswindt, Andre; Manser, Marta B.; Clutton-Brock, Tim H.; Ozgul, Arpat (The Royal Society, 2019-02)
    Dispersal is a key process influencing the dynamics of socially and spatially structured populations. Dispersal success is determined by the state of individuals at emigration and the costs incurred after emigration. ...
  • Decline and fall : the causes of group failure in cooperatively breeding meerkats 
    Duncan, Chris; Manser, Marta B.; Clutton-Brock, Tim H. (Wiley Open Access, 2021-11)
    In many social vertebrates, variation in group persistence exerts an important effect on individual fitness and population demography. However, few studies have been able to investigate the failure of groups or the causes ...
  • Discrete call types referring to predation risk enhance the efficiency of the meerkat sentinel system 
    Rauber, Ramona; Manser, Marta B. (Nature Publishing Group, 2017-03-17)
    Sentinel behaviour, a form of coordinated vigilance, occurs in a limited range of species, mostly in cooperative breeders. In some species sentinels confirm their presence vocally by giving a single sentinel call type, ...
  • Disentangling influence over group speed and direction reveals multiple patterns of influence in moving meerkat groups 
    Averly, Baptiste; Sridhar, Vivek; Demartsev, Vlad; Gall, Gabriella; Manser, Marta B.; Strandburg‑Peshkin, Ariana (Nature Research, 2022-08-16)
    Animals that travel together in groups must constantly come to consensus about both the direction and speed of movement, often simultaneously. Contributions to collective decisions may vary among group members, yet inferring ...
  • Dispersal decreases survival but increases reproductive opportunities for subordinates in a cooperative breeder 
    Maag, Nino; Paniw, Maria; Cozzi, Gabriele; Manser, Marta B.; Clutton-Brock, Tim H.; Ozgul, Arpat (University of Chicago Press, 2022-05)
    In most socially structured populations, the formation of new groups depends on the survival and reproduction of dispersing individuals. Quantifying vital rates in dispersers, however, is difficult because of the logistic ...
  • Dispersal-induced social stress prolongs gestation in wild meerkats 
    Maag, Nino; Cozzi, Gabriele; Seager, David; Manser, Marta B.; Sickmueller, Anna; Hildebrandt, Thomas B.; Clutton-Brock, Tim H.; Ozgul, Arpat (Royal Society Publishing, 2023-06)
    In the majority of mammals, gestation length is relatively consistent and seldom varies by more than 3%. In a few species, females can adjust gestation length by delaying the development of the embryo after implantation. ...
  • Diurnal oscillations in gut bacterial load and composition eclipse seasonal and lifetime dynamics in wild meerkats 
    Risely, Alice; Wilhelm, Kerstin; Clutton-Brock, Tim H.; Manser, Marta B.; Sommer, Simone (Nature Research, 2021-10)
    Circadian rhythms in gut microbiota composition are crucial for metabolic function, yet the extent to which they govern microbial dynamics compared to seasonal and lifetime processes remains unknown. Here, we investigate ...
  • Dominance loss and tenure maintenance in Kalahari meerkats 
    Duncan, Chris; Thorley, Jack; Manser, Marta B.; Clutton-Brock, Tim H. (Oxford University Press, 2023-11)
    In many social species, both the acquisition of dominance and the duration that individuals maintain their status are important determinants of breeding tenure and lifetime reproductive success. However, few studies have ...
  • Effect of group size and experience on the ontogeny of sentinel calling behaviour in meerkats 
    Rauber, Ramona; Manser, Marta B. (Elsevier, 2021-01)
    Increased vulnerability to predation results in young individuals of many species experiencing higher predation pressure than adults. Consequently, the production of antipredator-related calls by young can differ from that ...
  • The effects of recruitment to direct predator cues on predator responses in meerkats 
    Zottl, Markus; Lienert, Raphaela; Clutton-Brock, Tim H.; Millesi, Eva; Manser, Marta B. (Oxford University Press, 2013)
    Behavioral responses of animals to direct predator cues (DPC; e. g. urine) are common and may improve their survival. We investigated wild meerkat (Suricata suricatta) responses to DPCs by taking an experimental approach. ...
  • Experience of the signaller explains the use of social versus personal information in the context of sentinel behaviour in meerkats 
    Rauber, R.; Manser, Marta B. (Nature Publishing Group, 2018-08-23)
    To maximise foraging opportunities while simultaneously avoiding predation, group-living animals can obtain personal information on food availability and predation risk and/or rely on social information provided by group ...
  • Genetic variance in fitness indicates rapid contemporary adaptive evolution in wild animals 
    Bonnet, Timothee; Morrissey, Michael B.; De Villemereuil, Pierre; Alberts, Susan C.; Arcese, Peter; Bailey, Liam D.; Boutin, Stan; Brekke, Patricia; Brent, Lauren J.N.; Camenisch, Glauco; Charmantier, Anne; Clutton-Brock, Tim H.; Cockburn, Andrew; Coltman, David W.; Courtiol, Alexandre; Davidian, Eve; Evans, Simon R.; Ewen, John G.; Festa-Bianchet, Marco; De Franceschi, Christophe; Gustafsson, Lars; Honer, Oliver P.; Houslay, Thomas M.; Keller, Lukas F.; Manser, Marta B.; McAdam, Andrew G.; McLean, Emily; Nietlisbach, Pirmin; Osmond, Helen L.; Pemberton, Josephine M.; Postma, Erik; Reid, Jane M.; Rutschmann, Alexis; Santure, Anna W.; Sheldon, Ben C.; Slate, Jon; Teplitsky, Celine; Visser, Marcel E.; Wachter, Bettina; Kruuk, Loeske E.B.
