Biased escorts: offspring sex, not relatedness explains alloparental care patterns in a cooperative breeder (2017)
Journal Article
Vitikainen, E. I. K., Marshall, H. H., Thompson, F. J., Sanderson, J. L., Bell, M. B. V., Gilchrist, J. S., Hodge, S. J., Nichols, H. J., & Cant, M. A. (2017). Biased escorts: offspring sex, not relatedness explains alloparental care patterns in a cooperative breeder. Proceedings of the Royal Society B: Biological Sciences, 284(1854), 20162384. https://doi.org/10.1098/rspb.2016.2384

Kin selection theory predicts that animals should direct costly care where inclusive fitness gains are highest. Individuals may achieve this by directing care at closer relatives, yet evidence for such discrimination in vertebrates is equivocal. We i...

Explaining negative kin discrimination in a cooperative mammal society (2017)
Journal Article
Thompson, F. J., Cant, M. A., Marshall, H. H., Vitikainen, E. I. K., Sanderson, J. L., Nichols, H. J., Gilchrist, J. S., Bell, M. B. V., Young, A. J., Hodge, S. J., & Johnstone, R. A. (2017). Explaining negative kin discrimination in a cooperative mammal society. Proceedings of the National Academy of Sciences, 114(20), 5207-5212. https://doi.org/10.1073/pnas.1612235114

Kin selection theory predicts that, where kin discrimination is possible, animals should typically act more favorably toward closer genetic relatives and direct aggression toward less closely related individuals. Contrary to this prediction, we prese... Read More about Explaining negative kin discrimination in a cooperative mammal society.

Evidence of oxidative shielding of offspring in a wild mammal (2016)
Journal Article
Vitikainen, E. I. K., Cant, M. A., Sanderson, J. L., Mitchell, C., Nichols, H. J., Marshall, H. H., Thompson, F. J., Gilchrist, J. S., Hodge, S. J., Johnstone, R. A., & Blount, J. D. (2016). Evidence of oxidative shielding of offspring in a wild mammal. Frontiers in Ecology and Evolution, 4, Article 58. https://doi.org/10.3389/fevo.2016.00058

Oxidative damage has been proposed as a potential mechanism underlying a life history tradeoff between survival and reproduction. However, evidence that reproduction is associated with increased oxidative damage is equivocal, and some studies have fo...

Reproductive competition triggers mass eviction in cooperative banded mongooses (2016)
Journal Article
Thompson, F. J., Marshall, H. H., Sanderson, J. L., Vitikainen, E. I. K., Nichols, H. J., Gilchrist, J. S., Young, A. J., Hodge, S. J., & Cant, M. A. (2016). Reproductive competition triggers mass eviction in cooperative banded mongooses. Proceedings of the Royal Society B: Biological Sciences, 283(1826), 20152607. https://doi.org/10.1098/rspb.2015.2607

In many vertebrate societies, forced eviction of group members is an important determinant of population structure, but little is known about what triggers eviction. Three main explanations are: (i) the reproductive competition hypothesis, (ii) the c... Read More about Reproductive competition triggers mass eviction in cooperative banded mongooses.

The cost of dominance: suppressing subordinate reproduction affects the reproductive success of dominant female banded mongooses. (2012)
Journal Article
Bell, M. B. V., Nichols, H. J., Gilchrist, J., Cant, M. A., & Hodge, S. J. (2012). The cost of dominance: suppressing subordinate reproduction affects the reproductive success of dominant female banded mongooses. Proceedings of the Royal Society B: Biological Sciences, 279, 619-624. https://doi.org/10.1098/rspb.2011.1093

Social species show considerable variation in the extent to which dominant females suppress subordinate reproduction. Much of this variation may be influenced by the cost of active suppression to dominants, who may be selected to balance the need to...

Reproductive control via eviction (but not the threat of eviction) in banded mongooses (2010)
Journal Article
Cant, M. A., Hodge, S. J., Bell, M. B. V., Gilchrist, J., & Nichols, H. J. (2010). Reproductive control via eviction (but not the threat of eviction) in banded mongooses. Proceedings of the Royal Society B: Biological Sciences, 277, 2219-2226. https://doi.org/10.1098/rspb.2009.2097

Considerable research has focused on understanding variation in reproductive skew in cooperative animal societies, but the pace of theoretical development has far outstripped empirical testing of the models. One major class of model suggests that dom... Read More about Reproductive control via eviction (but not the threat of eviction) in banded mongooses.

Caregivers recognize and bias response towards individual young in a cooperative breeding mammal, the banded mongoose (2008)
Journal Article
Gilchrist, J., Otali, E., & Mwanguhya, F. (2008). Caregivers recognize and bias response towards individual young in a cooperative breeding mammal, the banded mongoose. Journal of Zoology, 275, 41-46. https://doi.org/10.1111/j.1469-7998.2007.00405.x

In research on parental care and cooperative breeding an issue is whether caregivers recognize individual young and therefore preferentially care for those young that will maximize inclusive fitness gains. This field study experimentally evaluates wh... Read More about Caregivers recognize and bias response towards individual young in a cooperative breeding mammal, the banded mongoose.

Aggressive monopolization of mobile carers by young of a cooperative breeder (2008)
Journal Article
Gilchrist, J. (2008). Aggressive monopolization of mobile carers by young of a cooperative breeder. Proceedings of the Royal Society B: Biological Sciences, 275, 2491-2498. https://doi.org/10.1098/rspb.2008.0597

Competition between young of the same brood or litter is of particular interest in the fields of behavioural and evolutionary ecology, because the competing individuals are likely to be closely related, where evolutionary theory predicts a greater de...
