Phylogenetic analysis of the ecology and evolution of mammalian sleep (2008)
Journal Article
Capellini, I., Barton, R. A., McNamara, P., Preston, B. T., & Nunn, C. L. (2008). Phylogenetic analysis of the ecology and evolution of mammalian sleep. Evolution, 62(7), 1764-1775. https://doi.org/10.1111/j.1558-5646.2008.00392.x

The amount of time asleep varies greatly in mammals, from 3 h in the donkey to 20 h in the armadillo. Previous comparative studies have suggested several functional explanations for interspecific variation in both the total time spent asleep and in r...

Habitat primary production and the evolution of body size within the hartebeest clade (2007)
Journal Article
Capellini, I., & Gosling, L. M. (2007). Habitat primary production and the evolution of body size within the hartebeest clade. Biological journal of the Linnean Society, 92(3), 431-440. https://doi.org/10.1111/j.1095-8312.2007.00883.x

Local adaptation is a key process in the evolution of biological diversity but relatively few studies have identified the selective forces that drive trait divergence at low taxonomic levels, particularly amongst mammals. Variation in body size acros... Read More about Habitat primary production and the evolution of body size within the hartebeest clade.

The phylogeny of sleep database : a new resource for sleep scientists (2007)
Journal Article
McNamara, P., Capellini, I., Harris, E., Nunn, C. L., Barton, R. A., & Preston, B. (2007). The phylogeny of sleep database : a new resource for sleep scientists. The open sleep journal, 1(1), 11-14. https://doi.org/10.2174/1874620900801010011

We have constructed a database that describes the sleeping characteristics of 127 different mammalian species representing 46 families across 17 orders. The data were extracted from 178 separate references that were found using standardized search pr... Read More about The phylogeny of sleep database : a new resource for sleep scientists.

The evolution of fighting structures in hartebeest (2006)
Journal Article
Capellini, I. (2006). The evolution of fighting structures in hartebeest. Evolutionary Ecology Research, 8(6), 997 - 1011

Question: Is sexual selection for the evolution of larger horns and related fighting structures opposed by food constraints in bovids? Data studied: Horn circumference and length, pedicel height, skull weight, and body size (skull length) were measur... Read More about The evolution of fighting structures in hartebeest.

Evolution of body size in the genus Damaliscus: a comparison with hartebeest Alcelaphus spp. (2006)
Journal Article
Capellini, I. (2006). Evolution of body size in the genus Damaliscus: a comparison with hartebeest Alcelaphus spp. Journal of Zoology, 270(1), 139-146. https://doi.org/10.1111/j.1469-7998.2006.00100.x

In species with low levels of sexual size dimorphism, it may be relatively easy to detect the role of natural selection in the evolution of body size. Habitat primary production (HPP) appears to be a key factor in the divergence of size in the harteb...
