Empirical parameterisation and dynamical analysis of the allometric Rosenzweig-MacArthur equations.

PLoS ONE, 2023
Allometric settings of population dynamics models are appealing due to their parsimonious nature and broad utility when studying system level effects.

Short-term temperature fluctuations increase disease in a Daphnia-parasite infectious disease system.

PLoS Biology, 2023
Climate change has profound effects on infectious disease dynamics, yet the impacts of increased short-term temperature fluctuations on disease spread remain poorly understood.

A new flexible model for maintenance and feeding expenses that improves description of individual growth in insects

Scientific Reports, 2023
Metabolic theories in ecology interpret ecological patterns at different levels through the lens of metabolism, typically applying allometric scaling to describe energy use. This requires a sound theory for individual metabolism.

The megabiota are disproportionately important for biosphere functioning

Nature Communications, 2020
Human-driven losses of megafauna and megaflora may have disproportionate ecological consequences. Here, the authors combine metabolic scaling theory and global simulation models to show that past and continued reduction of megabiota have and will ...

Body size has primacy over stoichiometric variables in nutrient excretion by a tropical stream fish community

Scientific Reports, 2022
Ecological Stoichiometry (ES) and the Metabolic Theory of Ecology (MTE) are the main theories used to explain consumers’ nutrient recycling. ES posits that imbalances between an animal’s body and its diet stoichiometry determine its nutrient excretion ...

Preserving neural function under extreme scaling [PDF]

, 2013
Important brain functions need to be conserved throughout organisms of extremely varying sizes. Here we study the scaling properties of an essential component of computation in the brain: the single neuron. We compare morphology and signal propagation of

Dynamic allometry in coastal overwash morphology [PDF]

Earth Surface Dynamics, 2020
Allometry refers to a physical principle in which geometric (and/or metabolic) characteristics of an object or organism are correlated to its size. Allometric scaling relationships typically manifest as power laws.

Body-Mass Scaling of Metabolic Rate: What are the Relative Roles of Cellular versus Systemic Effects?

Biology, 2015
The reason why metabolic rate often scales allometrically (disproportionately) with body mass has been debated for decades. A critical question concerns whether metabolic scaling is controlled intrinsically at the intracellular level or systemically at ...

Scaling up the curvature of mammalian metabolism

Frontiers in Ecology and Evolution, 2014
A curvilinear relationship between mammalian metabolic rate and body size on a log-log scale has been adopted in lieu of thelongstanding concept of a 3/4 allometric relationship (Kolokotrones et al. 2010).
