“Ecomorphological analyses have identified a number of important evolutionary trends in vertebrate limb design, but the relationships between daily travel distance, locomotor ecology, and limb length in terrestrial animals remain

poorly understood. In this paper I model the net rate of energy intake as a function of foraging efficiency, and thus of locomotor economy; improved economy leads to greater net energy intake. However, the relationship between locomotor economy and net intake is highly dependent on foraging efficiency;

only species with low foraging efficiencies experience strong selection pressure for improved locomotor economy and increased limb length. Examining 237 terrestrial species, ABT-737 in vivo I find that nearly all taxa obtain sufficiently high foraging efficiencies that selection for further increases in economy is weak. Thus selection pressures for increased economy and limb length among living terrestrial animals may be relatively weak and similar in magnitude across ecologically diverse species. The Economy Selection Pressure model for locomotor economy may be useful in investigating the evolution of limb design in early terrestrial taxa and the coevolution of foraging ecology and

locomotor anatomy in lineages with Orotic acid low foraging efficiencies. (C) 2011 Elsevier Ltd. All rights reserved.”
“Heroin addicts can benefit from methadone substitution therapy. However, little is known about the significance of pre-exposure to opioids for psychoactive effects of methadone. We modeled some behavioral and neurobiological aspects of the opioid abuse-related phenomena in Sprague-Dawley rats, using morphine (10 mg/kg/day) or methadone (1 or 2 mg/kg/day) treatment (14 doses over a 16-day period) followed by 2-week withdrawal and methadone challenge; control rats were given 0.9% NaCl treatment and methadone challenge by the same schedule. Locomotor response to the challenge showed substantial enhancement only after the morphine treatment. Fos immunohistochemistry in selected brain regions including cortex, nucleus accumbens, striatum and some parts of the hippocampus, thalamus and amygdala also revealed marked differences between the effects of the tested treatments. Sensitization of Fos response was found in a few regions of the morphine-treated rats. The rats given the higher methadone dose treatment showed a fairly weak tendency for sensitization that reached significance only in somatosensory cortex layer IV.
