“…Therefore, it is important that juveniles increase their exploration behavior with density if it helps them locating food resources. Adults, on the contrary, have a very low survival probability until the next breeding season (Leirs et al, 1993) where the benefits of increasing their exploration behavior do not outweigh the potential costs such as predator attraction (Jones & Godin, 2010;Rödel et al, 2015) and a higher metabolism (Careau & Garland, 2012;Careau, Thomas, Humphries, & Réale, 2008) and may potentially explain why adults do not increase their exploration with density. However, it is not clear if being more explorative increases survival.…”

Conspecific density and animal personality (consistent among‐individual differences in behavior) may both play an important role in disease ecology. Nevertheless, both factors have rarely been studied together but may provide insightful information in understanding pathogen transmission dynamics. In this study, we investigated how both personality and density affect viral infections both direct and indirectly, using the multimammate mice (Mastomys natalensis) and Morogoro arenavirus (MORV) as a model system. Using a replicated semi‐natural experiment, we found a positive correlation between MORV antibody presence and density, suggesting that MORV infection is density‐dependent. Surprisingly, slower explorers were more likely to have antibodies against MORV compared to highly explorative individuals. However, exploration was positively correlated with density which may suggest a negative, indirect effect of density on MORV infection. We have shown here that in order to better understand disease ecology, both personality and density should be taken into account.

“…Variation in this trait can considerably affect an animal's subsequent growth and development, with consequences for survival and reproduction (Albon, Clutton-Brock, & Guinness, 1987;Lindström, 1999;Quiniou, Dagorn, & Gaudré, 2002). Typically, offspring born with smaller size and with a lower postnatal growth often suffer from a higher mortality prior to weaning and beyond (Côté & Festa-Bianchet, 2001;Guinness, Clutton-Brock, & Albon, 1978;Magnabosco, Bernardi, Went, Cunha, & Bortolozzo, 2016;Maniscalco, 2014;Rödel et al, 2015;Rödel, Starkloff, Seltmann, Prager, & von Holst, 2009). …”

We asked whether within-litter differences in early body mass are associated with differences in house mouse pups' thermogenic performance and whether such variation predicts individual differences in competitive interactions for thermally more advantageous positions in the huddle. We explored pups' thermogenic performance in isolation by measuring changes in (maximal) peripheral body temperatures during a 5-min thermal challenge using infrared thermography. Changes in peripheral body temperature were significantly explained by individual differences in body mass within a litter; relatively lighter individuals showed an overall quicker temperature decrease leading to lower body temperatures toward the end of the thermal challenge compared to heavier littermates. Within the litter huddle, relatively lighter pups with a lower thermogenic performance showed consistently more rooting and climbing behavior, apparently to reach the thermally advantageous center of the huddle. This suggests that within-litter variation in starting body mass affects the pups' thermal and behavioral responses to environmental challenges.

“…This is particularly true for mammals, some of which serve as important model species in biomedical research (Freund et al, ; Lewejohann, Zipser, & Sachser, ; Rödel & Meyer, ). Although an increasing number of studies have assessed and could successfully show the existence of personality traits in young mammals around weaning by means of behavioral consistencies across time and context (Gracceva, Koolhaas, & Groothuis, ; Guenther, Finkemeier, & Trillmich, ; Herde & Eccard, ; Petelle, McCoy, Alejandro, Martin, & Blumstein, ; Rödel & Meyer, ; Rödel, Zapka, Talke, Kornatz, Bruchner, & Hedler, ), there have still been few studies of the development of personality in mammals from birth (reviews in Hudson, Bautista, Reyes‐Meza, Montor, & Rödel, ; Hudson, Rangassamy, Saldaña, Bánszegi, & Rödel, ; Stamps & Groothuis, ). This is understandable given the problem of testing dependent young without disturbing the often close mother–young relationship and affecting normal development.…”

Study of the development of individuality is often hampered by rapidly changing behavioral repertoires and the need for minimally intrusive tests. We individually tested 33 kittens from eight litters of the domestic cat in an arena for 3 min once a week for the first 3 postnatal weeks, recording the number of separation calls and the duration of locomotor activity. Kittens showed consistent and stable individual differences on both measures across and within trials. Stable individual differences in the emission of separation calls across trials emerged already within the first 10 s of testing, and in locomotor activity within the first 30 s. Furthermore, individual kittens' emission of separation calls, but not their locomotor activity, was highly stable within trials. We conclude that separation calls provide an efficient, minimally intrusive and reliable measure of individual differences in behavior during development in the cat, and possibly in other species emitting such calls.
