DOI: 10.1002/bies.201700001
Abstract: Heterogeneity in mitochondrial content has been previously suggested as a major contributor to cellular noise, with multiple studies indicating its direct involvement in biomedically important cellular phenomena. A recently published dataset explored the connection between… read more here.

DOI: 10.1093/icb/icac038
Abstract: Metabolic rate (MR) usually changes (scales) out of proportion to body mass (BM) as MR = aBMb, where a is a normalisation constant and b is the scaling exponent that reflects how steep this change is. This… read more here.

The Evolution of Offspring Size: A Metabolic Scaling Perspective
Sign Up to like & getrecommendations! Published in 2022 at "Integrative and Comparative Biology"
DOI: 10.1093/icb/icac076
Abstract: Abstract Size at the start of life reflects the initial per offspring parental investment—including both the embryo and the nutrients supplied to it. Initial offspring size can vary substantially, both within and among species. Within… read more here.

DOI: 10.1098/rspb.2022.1605
Abstract: Life's size and tempo are intimately linked. The rate of metabolism varies with body mass in remarkably regular ways that can often be described by a simple power function, where the scaling exponent (b, slope… read more here.

DOI: 10.1126/science.adf5188
Abstract: Froese and Pauly argue that our model is contradicted by the observation that fish reproduce before their growth rate decreases. Kearney and Jusup show that our model incompletely describes growth and reproduction for some species.… read more here.

DOI: 10.3389/fphys.2019.01166
Abstract: As an example of applying the evidential approach to statistical inference, we address one of the longest standing controversies in ecology, the evidence for, or against, a universal metabolic scaling relationship between metabolic rate and… read more here.
