Adult female mink were fed diets supplemented with 0, 0.001, 0.01, 0.1, 1, 10, or 100 ppb 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) for up to 125 days. There was a dose-dependent decrease in feed consumption and body weights indicative of the "wasting syndrome" previously reported for mink and other species exposed to chlorinated hydrocarbon compounds. Mortality reached 12.5, 62.5, and 100% by day 28 in the 1-, 10-, and 100-ppb groups, respectively, and by day 125, mortality increased to 62.5 and 100% in the 1- and 10-ppb groups, respectively. Adrenal gland weights were significantly greater in the three highest dose groups compared to the control group. The percentage of band neutrophils was also significantly greater in the TCDD-treated groups compared to the control. LC50 (+/- SE) values for 28 and 125 days of dietary exposure to TCDD were calculated to be 4.8 +/- 4.99 ppb and 0.85 +/- 0.64 ppb, respectively. Based on feed consumption of control mink, these LC50 concentrations approximate 0.264 and 0.047 microgram TCDD/kg body weight/day for the 28- and 125-day exposure periods, respectively. These results confirm the sensitivity of mink to TCDD.

“…To extend the analyses to a broader array of animals, I compiled additional data on hair density and body mass for 29 terrestrial nonprimate mammal species from the literature representing eight orders, and one primate, the Japanese macaque (Supplementary Material; hair density: Giacometti and Machida, ; Dawson and Brown, ; Voipio and Hissa, ; Jenkinson and Nay, ; McClure and Porter, ; Maurel et al, ; Korhonen, ; Webb and McClure, ; Flood et al, ; Reynolds, ; Fish et al, ; Sheriff et al, ; body mass: McClure and Porter, ; Webb and McClure, ; Vleck and Kenagy, 1987 in Lovegrove, ; Reynolds, ; Sidorovich et al, ; Pérez‐Barbería and Gordon, ; Jones et al, ; Sheriff et al, ). Mammals exhibit variable types of hair, and different terms are used to describe these different types of hair depending on the taxa being studied.…”

Brief communication: Hair density and body mass in mammals and the evolution of human hairlessness

Humans are unusual among mammals in appearing hairless. Several hypotheses propose explanations for this phenotype, but few data are available to test these hypotheses. To elucidate the evolutionary history of human "hairlessness," a comparative approach is needed. One previous study on primate hair density concluded that great apes have systematically less dense hair than smaller primates. While there is a negative correlation between body size and hair density, it remains unclear whether great apes have less dense hair than is expected for their body size. To revisit the scaling relationship between hair density and body size in mammals, I compiled data from the literature on 23 primates and 29 nonprimate mammals and conducted Phylogenetic Generalized Least Squares regressions. Among anthropoids, there is a significant negative correlation between hair density and body mass. Chimpanzees display the largest residuals, exhibiting less dense hair than is expected for their body size. There is a negative correlation between hair density and body mass among the broader mammalian sample, although the functional significance of this scaling relationship remains to be tested. Results indicate that all primates, and chimpanzees in particular, are relatively hairless compared to other mammals. This suggests that there may have been selective pressures acting on the ancestor of humans and chimpanzees that led to an initial reduction in hair density. To further understand the evolution of human hairlessness, a systematic study of hair density and physiology in a wide range of species is necessary.
