Allometric scaling in small colonies of the scleractinian coral Siderastrea siderea (Ellis and Solander).
Although most physiological traits scale allometrically in unitary organisms, it has been hypothesized that modularity allows for isometric scaling in colonial modular taxa. Isometry would allow increases in size without functional constraints, and is thought to be of central importance to the success of a modular design. Yet, despite its potential importance, scaling in these organisms has rec...
متن کاملHigh-Throughput Tissue Bioenergetics Analysis Reveals Identical Metabolic Allometric Scaling for Teleost Hearts and Whole Organisms
Organismal metabolic rate, a fundamental metric in biology, demonstrates an allometric scaling relationship with body size. Fractal-like vascular distribution networks of biological systems are proposed to underlie metabolic rate allometric scaling laws from individual organisms to cells, mitochondria, and enzymes. Tissue-specific metabolic scaling is notably absent from this paradigm. In the c...
متن کاملThe predominance of quarter-power scaling in biology
1. Recent studies have resurrected the debate over the value for the allometric scaling exponent that relates whole-organism metabolic rate to body size. Is it 3 / 4 or 2 / 3 ? This question has been raised before and resolved in favour of 3 / 4 . Like previous ones, recent claims for a value of 2 / 3 are based almost entirely on basal metabolic rate (BMR) in mammals. 2. Here we compile and ana...
متن کاملScaling of metabolism in Helix aspersa snails: changes through ontogeny and response to selection for increased size.
Though many are convinced otherwise, variability of the size-scaling of metabolism is widespread in nature, and the factors driving that remain unknown. Here we test a hypothesis that the increased expenditure associated with faster growth increases metabolic scaling. We compare metabolic scaling in the fast- and slow-growth phases of ontogeny of Helix aspersa snails artificially selected or no...
متن کاملOn the vegetative biomass partitioning of seed plant leaves, stems, and roots.
A central goal of comparative life-history theory is to derive the general rules governing growth, metabolic allocation, and biomass partitioning. Here, we use allometric theory to predict the relationships among annual leaf, stem, and root growth rates (GL, GS, and GR, respectively) across a broad spectrum of seed plant species. Our model predicts isometric scaling relationships among all thre...
