Many aspects of an animal's early development might potentially contribute to long-term individual differences in physiology and behavior. Here we asked whether differences among littermates of the domestic rabbit in the position in the litter huddle that they occupy during the early nest period might contribute to the development of distinct behavioral and physiological phenotypes. In each of 12 litters we determined the pup occupying the most peripheral, the most central, and an intermediate… 

Topics from this paper

Early development and the emergence of individual differences in behavior among littermates of wild rabbit pups
TLDR
Individual differences in behavior and associated differences in body temperature and growth are already present during early postnatal life, although such relationships can be easily overlooked, as they predominantly emerge as relative differences among littermates.
Contribution of within-litter interactions to individual differences in early postnatal growth in the domestic rabbit
TLDR
The observed developmental patterns were truly driven by pups' body mass relative to their current littermates rather than being a consequence of (epi)genetic effects potentially associated with their birth mass, underlines the importance of interactions among siblings in shaping individual differences in early growth and development largely independent of genetic factors.
Stable individual differences in separation calls during early development in cats and mice
TLDR
Brief separation experiments in young mammals, and particularly the measurement of separation calls, provide a promising approach to study the ontogeny of personality traits.
Sibling differences in litter huddle position contribute to overall variation in weaning mass in a small mammal
TLDR
Benefits in early growth arising from a more central position in the litter huddle are also apparent when comparing pups across all litters—even though there is typically a notable variation in growth among different litters, for example due to litter size and maternal (parity) effects.
Lactation does not alter the long-term stability of individual differences in behavior of laboratory mice on the elevated plus maze
TLDR
This study explores the stability of behavioral responses across a 43-day period by successively testing the animals on an elevated plus maze and finds clear evidence of individual consistency over time by means of positive significant correlations across the different tests.
Differential metabolism of brown adipose tissue in newborn rabbits in relation to position in the litter huddle.
TLDR
Findings confirm the contribution of early sibling relations to individual differences in growth and metabolic processes associated with thermoregulation in newborn rabbits.
Individual differences in behavior and heart rate variability across the preweaning period in the domestic horse in response to an ecologically relevant stressor
TLDR
Individual differences in behavior and heart rate variability of foals in response to brief maternal separations were consistent and were correlated from a very early age and contribute to an understanding of the expression of individual differences in physiology and behavior from a developmental perspective.
Competition in newborn rabbits for thermally advantageous positions in the litter huddle is associated with individual differences in brown fat metabolism
TLDR
During early development littermates of the rabbit experience differing degrees of activation of the sympathetic nervous system as a consequence of exposure to different thermal environments associated with different positions in the litter huddle, suggesting differences in the physiological response to cold.
Individual differences in early body mass affect thermogenic performance and sibling interactions in litter huddles of the house mouse
TLDR
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 huddled, suggesting that within-litter variation in starting body mass affects the pups' thermal and behavioral responses to environmental challenges.
Within-litter differences in personality and physiology relate to size differences among siblings in cavies
TLDR
Physiological state variables were tightly correlated with personality traits and also influenced by the size rank within litter, suggesting that the size relative to littermates constitutes an important factor in shaping an individual's developmental trajectory.

Development of behavior in the litter huddle in rat pups: within- and between-litter differences.
TLDR
There to be consistent between- litter as well as within-litter differences in behavioral patterns during early life, which might have important implications for an individual's long-term behavioral and physiological performance.
The effect of siblings on early development: a potential contributor to personality differences in mammals.
TLDR
It is concluded that in mammals, individual differences in early growth, physiology and behavior potentially important for the development of animal personality, are shaped to an appreciable extent by early sibling relations and that this little-researched field deserves closer attention.
Long-term consequences of early development on personality traits: a study in European rabbits
TLDR
Evidence is provided that an animal's early development can exert long-term effects on its personality type, although it is not clear whether body mass per se or some correlated physiological features drive the observed relationships.
Differential development of body equilibrium among littermates in the newborn rabbit.
TLDR
It is reported that high birth weight pups are also better able to maintain body equilibrium, which provides further support for the usefulness of birth weight, not only as an absolute measure but also relative to the weight of other littermates, as a predictor of different developmental trajectories, behavioral and physiological, among same-age siblings in this mammal.
Littermate presence enhances motor development, weight gain and competitive ability in newborn and juvenile domestic rabbits.
TLDR
Before weaning, it was found that pups raised separately from their littermates obtained less milk, and showed lower weight gain and slower development of the ability to maintain body equilibrium than their litter-raised sibs, which was the case even though the two groups did not differ in birth weight or in the ratio of converting milk into body mass in their temperature-controlled nest boxes.
The Pattern of Behaviour of Rabbit Pups in the Nest
TLDR
The ability of the pups to anticipate the nursing and the their thermoregulatory self-sufficiency may contribute to shortening the time rabbit does must spend in the nest.
Features of the early juvenile development predict competitive performance in male European rabbits
TLDR
It is pointed out that parameters of the early development are involved in shaping the competitive performance during later life via other mechanisms than just by promoting a high adult body mass.
Do newborn domestic rabbits Oryctolagus cuniculus compete for thermally advantageous positions in the litter huddle?
TLDR
In newborn rabbits, competition for the mother’s milk exists alongside mutual “cooperative” benefits of littermate presence, and it is concluded that rather than competing for thermally advantageous positions within the huddle newborn rabbits share out thermologically advantageous positions as they move in a continual dynamic flow through it.
Separating maternal and litter-size effects on early postnatal growth in two species of altricial small mammals
TLDR
Litter size, i.e. sibling number, was the most important factor, followed by maternal mass or age, and then by mothers' history of previous reproductive activity, and it is likely that these findings will be valid for other mammalian species giving birth to large litters of altricial young.
Behavioral styles in European rabbits: Social interactions and responses to experimental stressors
TLDR
The study concludes that the study fails to support the existence of domain-general behavioral phenotypes in European rabbits because of a lack of consistent behavioral styles across both tests.
