Abstract:
We examined behaviour in adult eastern chipmunks (Tamias striatus) from 1992 to 1995 in a landscape altered by forest clear-cutting in central Pennsylvania, U.S.A. Our objective was to compare behaviour patterns in chipmunk populations occupying mature continuous forest versus mature forested corridors (100 m wide) surrounded by clearcuts. Chipmunks spent a significantly greater proportion of their time pausing in the forested-corridor habitat than in the continuous-forest habitat. In addition, chipmunks spent less time locomoting and foraging in the forested-corridor habitat than in the conti

Abstract:
When food patches vary in quality over time, sampling by repeated visits can allow animals to track this variation and improve their foraging success. Sampling, however, requires spending time visiting patches that are currently poor. The optimal investment in sampling should depend on characteristics of the patch, the animal, and the environment, but there are few empirical studies of these relationships in nature. Here, we describe discovery, exploitation, and sampling of randomly varying artificial food patches by free-ranging eastern chipmunks ( Tamias striatus (L., 1758)). Chipmunks effec

Abstract:
Eastern chipmunks ( Tamias striatus (L., 1758)) capitalize on pulsed production of storable seed from masting trees by accumulating large, long-term larder hoards in their burrow. Since this species does not accumulate fat, hoarded food is the sole source of energy used during hibernation and inactive periods. Because hoards can be very large, they offer chipmunks the possibility of forgoing aboveground foraging when seeds or nuts are not abundant on the forest floor. Here, we present evidence that at least 82 chipmunks in two different populations interrupted aboveground activity for 9–11 mon

Abstract:
Most research pertaining to the diet of North American weasels has been conducted in agricultural areas and may not be representative of diets in forested regions. Ermine carcasses (N = 155) collected from trappers during a two-week harvest (16-30 November 1996) in forested New Brunswick were analyzed for food habits. The contents of 81 stomachs and 98 gastrointestinal tracts (N = 179) were considered as separate eating events and used in the calculation of the percent frequency of occurrence. Results suggest that soricids (28.0%), arvicolines (24.6%), and cricetines (17.3%) comprised two-thir

Abstract:
Body mass has been proposed as a factor that contributes to the onset of puberty in some species of mammals. In this study we examined the relationship between body mass and primiparity in the eastern chipmunk (Tamias striatus) by comparing females that reproduced and those that did not during any given breeding opportunity. We also investigated whether season of birth influenced the season of first reproduction. No differences in season of first reproduction were observed between spring-born and fall-born females. Females that produced a litter had significantly greater body mass than did fem

Abstract:
Life-history allocation trade-offs are dynamic over time and space according to the ecological and demographical context. Fluctuations in food availability can affect physiological trade-offs like oxidative status regulation, reflecting the balance between pro-oxidant production and antioxidant capacity. Monitoring the spatio-temporal stability of oxidative status in natural settings may help understanding its importance in ecological and evolutionary processes. However, few studies have yet conducted such procedures in wild populations. Here, we monitored individual oxidative status in a wild

Abstract:
Predation risk may have a profound impact upon foraging behaviour. I studied how potential exposure to predation affected the foraging behaviour of eastern chipmunks (Tamias striatus). I measured the time taken to approach a patch ("approach time"), the period of residency in the patch ("patch residence time"), the degree of vigilance, and the size of the load of seeds taken by chipmunks foraging at patches (food trays) in both open and forested sites. Chipmunks have shorter approach times to trays in the open than to trays amongst forest cover. Although the load size taken did not differ betw

Abstract:
Measuring activity of small mammals in the field is challenging because they are often out of view. We used a novel method, based on temperatures of collar radio transmitters, to quantify the proportion of time eastern chipmunks (Tamias striatus (L., 1758)) spent active, curled up resting, and torpid during the summer and fall of 2 years in southern Quebec. Time active over the 24 h day was lower in a nonmast (8%) than a mast (26%) year. In the mast year, activity varied strongly from a low of 7% during the summer lull to a high of 35% in the fall. Chipmunks that exploited a feeder had higher

Abstract:
When an animal has found and consumed food at a new location, information about whether and when food will be present again could improve future foraging efficiency. A series of rapid returns followed by less frequent visits and finally abandonment of the patch could provide such information. By analogy with area-concentrated (area-restricted) search, we call this hypothesized pattern “time-concentrated sampling”. We tested whether eastern chipmunks ( Tamias striatus (L., 1758)) would show time-concentrated sampling in the field and whether the pattern of visits would be affected by patch valu

Abstract:
Small endotherms typically have elevated and relatively invariant rates of metabolism, but adaptations such as food hoarding and hibernation endow some species with considerable energetic flexibility in responding to resource fluctuations. I examined the interactions between resource availability, food hoarding, and hibernation in a population of eastern chipmunks (Tamias striatus) subjected to seasonal and multi-annual periods of resource shortage. Incompatibility of torpor and digestion could be an important constraint associated with relying on stored food rather than body fat during hibern

Abstract:
In a variable environment, the ability to track food resources that vary in time and space may increase the foraging efficiency of individuals. Tracking can be accomplished by repeatedly visiting patches, but this sampling will be economical only if its benefits outweigh its costs. I examined the effects of patch characteristics and social factors on sampling using simulation models and both large- and small-scale field experiments on eastern chipmunks ( Tamias striatus). In the first experiment, chipmunks discovered large renewing patches within a few days, sampled them frequently enou

Abstract:
Little theoretical or empirical research has examined how an animal that has found and exploited a new patch should determine whether and when it will renew. A rapid series of visits to the patch should provide information concerning the probability of a quick renewal. If a renewal is not encountered, however, a subsequent decrease in the rate of visits should allow monitoring of the patch at minimal cost. After a long period without renewal, a patch should not be visited at all. By analogy with area-concentrated search, I propose the term 'time-concentrated sampling' (TCS) for this pat
