“…The tight relationship between time allocated to resting, resting postures and seasonal changes seems to be a paramount thermoregulatory strategy and has been repeatedly observed in studies on lemurs (Morland, 1993; Pereira et al, 1999), on other primates (Stelzner and Hausfater, 1986; Schino and Troisi, 1990; Dasilva, 1993; Thompson et al, 1994; Bicca‐Marquez and Calegaro‐Marquez, 1998; Pochron, 2000; Hill et al, 2004; Hill, 2006; Hanya et al, 2007; Campos and Fedigan, 2009; Kosheleff and Anderson, 2009), and on mammals in general (Bradley and Hudson, 1974; Hasler and Sorenson, 1974; Körtner and Geiser, 2000). Our results show that seasonal fluctuations had a major role in shaping the four types of behavioral thermoregulation used by collared lemurs.…”

“…Among mammals, both nonplacental semi‐poikilotherms (McNab, 1978; Rübsamen et al, 1983; Körtner and Geiser, 2000; McCarron et al, 2001; Brice et al, 2002; Grigg et al, 2003; Bethge et al, 2004) and placental endotherms (Bradley and Hudson, 1974; Hasler and Sorenson, 1974) use the full set of behavioral thermoregulatory strategies, although in different combinations and in different proportions. Primates have been shown to resort to microhabitat selection, adjustments in posture and activity, and huddling as responses to environmental temperature ( Microcebus murinus , Aujard et al, 1998; Varecia variegata , Morland, 1993; Leontopithecus rosalia , Thompson et al, 1994; Alouatta caraya , Bicca‐Marquez and Calegaro‐Marquez, 1998; Colobus polykomos , Dasilva, 1993; Papio cynocephalus , Stelzner and Hausfater, 1986; Pochron, 2000; Hill and Dunbar, 2002; Hill et al, 2004; Hill, 2006; Macaca fuscata , Schino and Troisi, 1990; Hanya et al, 2007; Cebus capucinus , Campos and Fedigan, 2009; Pan troglodytes , Takemoto, 2004; Kosheleff and Anderson, 2009).…”

Primates deal with fluctuations of the thermal environment by both physiological and behavioral mechanisms of thermoregulation. In this article we focus on non-hibernating lemurs, which are hypometabolic and have to cope with a seasonal environment. Behavioral thermoregulation has received little attention compared with specific physiological adaptations to seasonality, i.e., hibernation and torpor, which characterize a number of lemurs. We investigated the role of seasonality and dietary-related factors in determining frequencies of resting, social and postural thermoregulation, and microhabitat selection in collared lemurs, Eulemur collaris. We observed two groups of collared lemurs over a 14-month period in the littoral forest of Sainte Luce, Southern Madagascar. Frequencies of total resting and time spent in huddling, prone, and curled postures were collected via 5-min instantaneous sampling. Microhabitat selection was evaluated as the proportion of time spent in the upper canopy as compared with other layers. Climatic variables were recorded by automatic data loggers, while dietary variables were derived from phenological data and nutritional analyses of the ingested food items. We weighted the combined effects of climatic and dietary variables on the different types of behavioral thermoregulation by means of canonical correlation analysis. The model with the strongest canonical correlation included a first root representing mainly feeding time, day length, and ambient temperature and a second root representing diet quality and height of feeding trees. The output indicated that collared lemurs adapt to thermal and dietary-related metabolic stress by adjusting resting time, social, and postural thermoregulation.

“…Because of this controversy, tree shrews have been subject to considerable anatomical and embryological study. In addition, there have been a number of behavioural studies of captive tree shrews which include those by Sprankel ( 1961 ); Vandenberg ( 1963 ); Kaufmann ( 1965); Conaway & Sorenson ( 1966a, b); Sorenson & Conaway (1968); Martin (1968); Sorenson (1970Sorenson ( , 1974; Hasler & Sorenson (1974). Although these studies have contributed valuable information on the biology of tree shrews there appears to be no published information, apart from cursory mention, on their ecology in the wild and this account presents some preliminary findings.…”

The ecology of the Common tree shrew, Tupaia glis in peninsular Malaysia

The Common tree shrew was studied over three and half years in tropical rainforest habitats in West Malaysia, using various trapping methods. It was more terrestrial than arboreal and the overall sex ratio remained close to unity. The main reproductive period was between February and June and the litter size invariably two. Some females bred more than once a season and the age at first pregnancy was seven months. Growth rate was measured from weaning to adult weight. Density varied from about two to five animals per hectare. The monthly survival rate was 0·75–0·93, and the maximum age recorded was over 4 years. The main period of emigration or mortality was during the breeding period or the North East Monsoon. The main food was invertebrates with some vegetable matter. These results support captive studies that T. glis are territorial with about two pairs per hectare prior to breeding. Predation did not seem to be important. Although survival resembled that of temperate insectivores, the litter size was more like lower primates. The annual breeding coincided with the abundance of invertebrates after the dry season, also shown by insectivorous birds. The low production of young was compensated for by the relatively high longevity of adults.

“…Adult female residents are often tolerated in territorial invasions by neighbouring adult females (KAWAMICHI • KAWAMICHI, 1979). Also in captivity, adult females sleep together in one nest box in T. glis (KAUFMANN, 1965), T. long# pes (SORENSON & CONAWAY, 1966) and T. chinensis SORENSON, 1970;HASLER & SORENSON, 1974). On the other hand, tolerance between males has hardly been observed in captive tree shrews of various species as well as in T. glis in our field study.…”

“…However, many adult females were assumed to be pregnant when other females disappeared synchronously in late January since this time is one month after the onset of mating and just prior to frequent oestrus observations. Observations of tree shrews in captivity have shown that "pregnancy has produced marked anti-social aggressiveness in the females" of T. glis (HENDRICKSON, 1954) and that oestrous females were aggressive towards other females in T. tongipes (SoRENSON & CONAWAY, 1966) and T. chinensis' (HASLER & SORENSON, 1974). However, it cannot be determined yet whether or not the increase of aggressiveness observed in captivity is connected directly with spatial exclusion from groups in the wild.…”

ABSTRACT. Field observations on 117 tree shrews (Tupaia glis) were conducted over a period of six months in Singapore. Of 19 groups (pairs or harems, with or without offspring), nine changed their composition mainly through the disappearance of juveniles. Juvenile males tended to disappear earlier than juvenile females. The areas used by the groups remained stable throughout their disappearance and membership changes. The onset of mating was observed in December, and the synchronous disappearance of offspring of the preceding reproduction typically occurred in late January. However, in one group, two litters coexisted. Offspring were usually excluded from their group presumably by the adult member of the same sex. Males disappeared at the timing of oestrus in their mothers, while females probably disappeared during the later stages of pregnancy of their mothers.
