Previously, Donelan and colleagues had found that the speed of nerve fiber conduction is nearly constant across the full size range of terrestrial animals.
Future increases in nitrogen deposition have been predicted to increase the size of these terrestrial and marine carbon sinks, but although higher rates of nitrogen deposition might enhance carbon uptake in northern and tropical forests, they will probably have less of an impact on ocean sink strength.
Various dynamics, such as Milankovich cycles (which impact solar energy distribution across the Earth's surface), or plate tectonics (which largely determine the location, size, and geology of terrestrial landmasses), affect climate patterns and determine the abiotic conditions to which ecosystems are exposed [23].
TEM uses spatially referenced information on climate, elevation, soils, and vegetation to make monthly estimates of C and N fluxes and pool sizes of the terrestrial biosphere.
The size of the liver of terrestrial mammals obeys the allometric scaling law over a weight range of >3 ∗ 106.
Thus, if man, the species, should ever become a cosmic imperialist, his stature will increase in proportion to the number and size of his extra-terrestrial colonies.
Because of the small size and terrestrial habitat of C. elegans it is likely that most globins in this species were selected for reasons other than enhancing hemoglobin synthesis capacity.
Although we were unable to obtain similar sample sizes for terrestrial systems, there were no significant between-system differences in mean effect size for any of the tested metrices.
The gray wolf (Canis lupus) is the accepted ancestor of the domestic dog (C. familiaris), but as a consequence of centuries of selective breeding, the latter had one of the greatest ranges of body size among terrestrial vertebrates.
For more than seven years, a group of German and Swiss scientists has made a concerted effort to test the limits of body size in terrestrial vertebrates and, in the process, try to answer these and other questions related to the enigma of sauropod gigantism.
