“…Our findings that the stress-induced rise in T b differed between years and seasons could be related to physiological and behavioural variations occurring at the population level. For example, eastern chipmunks are known to become much less active in summer, a phenomenon referred to as the summer ''lull'' (Elliot 1978;Yahner 1978). In our population, resting metabolic rate increases in fall compared to spring and summer (Careau, unpublished data).…”

In response to handling or other acute stressors, most mammals, including humans, experience a temporary rise in body temperature (T(b)). Although this stress-induced rise in T(b) has been extensively studied on model organisms under controlled environments, individual variation in this interesting phenomenon has not been examined in the field. We investigated the stress-induced rise in T(b) in free-ranging eastern chipmunks (Tamias striatus) to determine first if it is repeatable. We predicted that the stress-induced rise in T(b) should be positively correlated to factors affecting heat production and heat dissipation, including ambient temperature (T(a)), body mass (M(b)), and field metabolic rate (FMR). Over two summers, we recorded both T(b) within the first minute of handling time (T(b1)) and after 5 min of handling time (T(b5)) 294 times on 140 individuals. The mean ∆T(b) (T(b5) - T(b1)) during this short interval was 0.30 ± 0.02°C, confirming that the stress-induced rise in T(b) occurs in chipmunks. Consistent differences among individuals accounted for 40% of the total variation in ∆T(b) (i.e. the stress-induced rise in T(b) is significantly repeatable). We also found that the stress-induced rise in T(b) was positively correlated to T(a), M(b), and mass-adjusted FMR. These results confirm that individuals consistently differ in their expression of the stress-induced rise in T(b) and that the extent of its expression is affected by factors related to heat production and dissipation. We highlight some research constraints and opportunities related to the integration of this laboratory paradigm into physiological and evolutionary ecology.

“…A monogamous classification seems especially inappropriate in light of the polygynous mating strategies adopted by males later in the winter breeding season. Males engaged in both competitive mate searching for estrous females and scramble competition (Schwagmeyer and Woontner 1985); they also competed directly in multi-male "mating bouts" like those found in tree squirrels and eastern chipmunks (Farentinos 1972;Elliott 1978 ;Yahner 1978 ;Koford 1982). D. spectabilis apparently has considerable flexibility in its reproductive behavior, which is probably the best strategy to use in an environment that can change radically across seasons and years.…”

“…spectabilis has an exclusive territorial spacing system similar to diurnal rodents (tree squirrels and chipmunks) that mate polygynously (Smith 1968;Elliott 1978;Yahner 1978;Koford 1982). Males and females individually defend large dirt mounds, approximately 2-5 m in diameter, and the area immediately surrounding them (Schroder 1979;Schroder and Geluso 1975;Randall 1984).…”

“…Dunford (1970) also places them in a single category, "freezing and fixating," but does not make the function clear. Yahner (1977) places the "freezing and fixating'" in the "Threat" category. The authors believe ikat 'Freeze' and 'Still' have two separate connotations as discussed above.…”
