Shifts in metabolic scaling, production, and efficiency across major evolutionary transitions of life
The scalings of metabolic rate, population growth rate, and production efficiency with body size have changed across the evolutionary transitions, showing Kleiber’s 3/4 power scaling law does not apply universally across organisms. Expand
On the Regulation of Populations of Mammals, Birds, Fish, and Insects
It is found that rates of population growth are high at low population densities but, contrary to previous predictions, decline rapidly with increasing population size and then flatten out, for all four taxa. Expand
Producers and scroungers: A general model and its application to captive flocks of house sparrows
A mathematical model is presented which shows whether or not scroungers are maintained in a group, depending on their frequency and the group size, and tests in captive flocks of house sparrows found scrougers fared better when one of more producers were present. Expand
Strategies of digestion and defecation
Why are organisms usually bigger in colder environments? Making sense of a life history puzzle.
The resolution of this apparent paradox may be that the response of adult size to temperature is adaptive, but is constrained by a trade-off that can be understood in terms of von Bertalanffy's classic theory of growth. Expand
The allometry of ornaments and weapons.
This work shows how scaling exponents reflect the relative fitness advantages of ornaments vs. somatic growth by using a simple mathematical model of resource allocation during ontogeny and explains why interspecific allometries have consistently lower exponents than intraspecific ones. Expand
Metabolic ecology : a scaling approach
Each chapter focuses on a different process, level of organization, or kind of organism and provides an integrated framework that holds the promise for a unified theory of ecology. Expand
Likelihood-based estimation of microsatellite mutation rates.
Application to data composed of 118,866 parent-offspring transmissions of AC microsatellites supports the hypothesis that mutation rate increases exponentially with microsatellite length, with a suggestion that contractions become more likely than expansions as length increases and a stationary distribution for allele length maintained by mutational balance.

Optimal foraging when regulating intake of multiple nutrients
The approach was to construct a smooth fitness landscape over nutrient space, centred on a ‘target’ intake at which no fitness cost is incurred, and this leads to a natural classification of the simple possible fitness landscapes based on Taylor series approximations of landscape shape. Expand
