Thermoregulatory characteristics of slender lorises largely resemble those of other slow-moving Lorisidae: Body temperature is slightly below the normal mammalian level and basal metabolic heat production is only about half of the mass-specific standard. During cold exposure only a rather small body core is kept at a high temperature level whereas large parts of the body are allowed to cool. Contrary to the findings in other Lorisidae slender lorises are more tolerant against high environmental temperatures, largely due to the ability of considerably increasing evaporative cooling.

“…The greater bushbaby, for example, can eliminate only 1/3 at 33°C and 2/3 at 38°C of the internal heat load by evaporation (Muller & Jaksche 1980). These estimates are similar for the potto (Hildwein & Goffart 1975) and the slow loris (Muller 1979). It has thus been suggested that these animals were not forced to develop highly efficient mechanisms of evaporative cooling during evolution mainly owing to their nocturnal behaviour.…”

“…1989,24(2) manner except that temperatures above 28°C lead to a marked increase in body temperature (Muller & Jaksche 1980). In the slow loris and potto rectal temperature was highly variable, several degrees lower than in guinea pigs, cats and rabbits and showed a distinct correlation to the activity pattern of the animal (Hildwein & Goffart 1975;Muller 1979). The ability of bushbabies to maintain body temperature at low ambient temperatures, while other Lorisidae do not, may be due to a large increase in heat production and to their dense fur which offers excellent insulation.…”

“…Higher primates rely, to a large extent, on sweating to enhance evaporative cooling but in prosimians sweat glands are not thought to playa major role in thermoregulation (Hiley 1976). These primates rather promote heat loss by increasing respiratory frequency (Hildwein & Goffart 1975) and this may have caused the significant increase in respiratory exchange ratio found in the male group within the thermal neutral zone. Because bushbabies are found in areas where water resources are limited, using evaporative cooling as a long-term thermoregulatory mechanism would be disadvantageous to them.…”

Human dietary patterns and metabolic requirements are compared to those of nonhuman primate species in order to gain insights into the evolution of our nutritional needs. In general, primate diet quality (i.e., caloric and nutrient density) is inversely related to body size and total resting metabolic requirements (RMR). Humans, however, consume a diet of much higher quality than is expected for our size and metabolic needs. This energy-rich diet appears to reflect an adaptation to the high metabolic cost of our large brain. Among primates, the relative proportion of resting metabolic energy used for brain metabolism is positively correlated with relative diet quality. Humans represent the positive extreme, having both a very high quality diet and a large brain that accounts for 20-25% of resting metabolism. Evidence from the hominid fossil record implies that major changes in diet and relative brain metabolism occurred with the emergence of the genus Homo. © 1994 Wiley-Liss, Inc.
