Simple Summary The metabolic conversion of resources into living structures and processes
is fundamental to all living systems. The rate of metabolism ('fire of life') is critical for …

All life forms depend on the conversion of energy into biomass used in growth and
reproduction. For unicellular heterotrophs, the energetic cost associated with building a cell …

It has been hypothesized that vacuolar occupancy in mature root cortical parenchyma cells
regulates root metabolic cost and thereby plant fitness under conditions of drought …

Along with different life strategies, organisms have evolved dramatic cellular composition
differences. Understanding the molecular basis and fitness effects of these differences is key …

Understanding metabolic performance limitations is key to explaining the past, present and
future of life. We investigated whether heat tolerance in actively flying Drosophila …

The intrinsic sources of mortality relate to the ability to meet the metabolic demands of tissue
maintenance and repair, ultimately shaping ageing patterns. Anti-ageing mechanisms …

Morphological analyses of the internal anatomy are a milestone in different fields of animal
biology, such as physiology, development and reproduction, and systematic studies …

Along with differences in life histories, metazoans have also evolved vast differences in
cellularity, involving changes in the molecular pathways controlling the cell cycle. The extent …

Environmental gradients cause evolutionary and developmental changes in the cellular
composition of organisms, but the physiological consequences of these effects are not well …

Simple Summary Ontogenetic phase shift (ie, a sudden change) in metabolism has been
observed in several fish species during their early development, and understanding such …
