Plasma thyroxine (T4), triiodothyronine (T3) and iodide levels were measured from birth until 30 days of age in 17 Holstein x Friesian (HF), 7 Salers and 7 Charolais calves born at term. The response of plasma T4 and T3 levels to bovine thyrotropin (TSH) injection was also compared in two groups of 9 HF calves 3hrs and 21 days, respectively, after birth. In the HF calves, plasma T4 and T3 level...

plexity. This conclusion is conceptually similar to our own, and it little alters the broader impacts of our published findings; still, the general relevance of the issues warrants a response. In their reanalysis, Gutierrez-Ibanez et al. [2016] perform a ‘residual analysis’, which regresses body weight on brain weight with phylogenetic generalized least squares (PGLS) to obtain size-corrected r...

The high-frequency content observed in teleseisms recorded by seismometers can be produced either by the nonlinear behavior of seismometers and digitizers (Delorey et al. 2008; Hellweg et al. 2008) or by the real Earth response. The latter include scattering from small-scale heterogeneities during seismic wave propagation (e.g., Chen and Long 2000) and high-frequency radiations from the earthqu...

Comparative zoologists, evolutionary biologists, experimental biologists, and mechanical engineers make wonderful generalizations about the movements of different-sized running bipeds and quadrupeds (Heglund et al., 1974; McMahon, 1975; Alexander, 1976; Hoyt & Taylor, 1981; Garland, 1982; McMahon et al., 1987; Rome et al., 1988; Gatesy & Biewener, 1991; Farley et al.,1993; Cynthia & Farley, 199...
