Using behavioural and state variables to identify proximate causes of population change in a seabird (2005)
Journal Article
Lewis, S., Grémillet, D., Daunt, F., Ryan, P. G., Crawford, R. J., & Wanless, S. (2006). Using behavioural and state variables to identify proximate causes of population change in a seabird. Oecologia, 147(4), 606-614. https://doi.org/10.1007/s00442-005-

Changes in animal population size are driven by the interactions between intrinsic processes and extrinsic forces, and identifying the proximate mechanisms behind population change remains a fundamental question in ecology. Here we report on how meas... Read More about Using behavioural and state variables to identify proximate causes of population change in a seabird.

Parasitism of maternal investment selects for increased clutch size and brood reduction in a host (2005)
Journal Article
Cunningham, E. J., & Lewis, S. (2006). Parasitism of maternal investment selects for increased clutch size and brood reduction in a host. Behavioral ecology official journal of the International Society for Behavioral Ecology, 17(1), 126-131. https://doi.

The allocation of resources to young that will ultimately be left to die appears counterintuitive. Yet obligate brood reduction has evolved in a number of species, despite the waste of reproductive investment this may incur. Here we test whether broo...

Sex-specific foraging behaviour in tropical boobies: does size matter? (2005)
Journal Article
Lewis, S., Schreiber, E. A., Daunt, F., Schenk, G. A., Orr, K., Adams, A., …Hamer, K. C. (2005). Sex-specific foraging behaviour in tropical boobies: does size matter?. Ibis, 147(2), 408-414. https://doi.org/10.1111/j.1474-919x.2005.00428.x

Sex differences in the foraging behaviour of adults have been observed in a number of sexually size-dimorphic birds, and the usual inference has been that these sex-specific differences are driven primarily by differences in body size. An alternative... Read More about Sex-specific foraging behaviour in tropical boobies: does size matter?.
