Shifts in metabolic scaling, production, and efficiency across major evolutionary transitions of life.
Convergence of trophic interaction strengths in grassland food webs through metabolic scaling of herbivore biomass.
The metabolic scaling exponent (b) represents the increasing metabolic efficiency with body size; the values that we found for b (0.94 and 0.86) are somewhat higher than the previously reported value of 0.76 for A.
Size matters: plasticity in metabolic scaling shows body-size may modulate responses to climate change.
of antibiotics in reptiles: basis and limitations.
(2003), is based on the idea that metabolic scaling depends on the number and size of cells comprising an organism (Davison 1955).
In this paper, we analyze published data to determine metabolic scaling across species of Orthoptera, and additionally describe metabolic scaling in an ontogenetic series within a single species.
"Metabolic scaling is a many-splendored thing," he says.
"West and Brown deserve a great deal of credit for rekindling the interest of the scientific community in this phenomenon of metabolic scaling," Suarez says.
To determine whether scleractinian corals are free of allometric constraints, we quantified metabolic scaling
, measured as aerobic respiration, in small colonies ([less than or equal to]40 mm in diam.) of the scleractinian Siderastrea siderea.
The scaling relationships for Histioteuthis heteropsis (y = [2.10x.sup.-0.25[pm]0.14]; [r.sup.2] = 0.55; P [less than] 0.01; n = 11), Chiroteuthis calyx ([y = 4.20x.sup.-0.39[pm]0.25]); [r.sup.2] = 0.76; P = 0.01; n = 7), and Japetella diaphana ([y = 0.40x.sup.-0.29[pm]0.15]; [r.sub.2] = 0.88; P = 0.004; n = 11) were within the normal range found for aerobic metabolic scaling
in a variety of animals (Schmidt-Nielsen, 1984).
Previous observations on the intraspecific metabolic scaling
of gelatinous animals have found small or non-significant effects of size on oxygen consumption rate (e.g., Kremer et al., 1986; Larson, 1987b; Vernon, 1895).
