Glucocorticoids GC play a major role in this link through their baseline levels into the blood and their implication in stress responses to environmental perturbations. However, very few studies have investigated the long-term joint relationships between GC stress reactivity, life history, and behavior in natural conditions.
Here, we took advantage of the behavioral and life history differences among individual males and females of a wild population of eastern chipmunks Tamias striatus: We investigated how individual exploration, age, and reproduction were linked to level and intra-individual variability IIV of fecal cortisol metabolites over a 5-month period.
Our analyses revealed that female cortisol levels decreased during gestation and lactation compared with non-reproductive females.
We also found that slower exploring females and females with a smaller litter displayed higher IIV in fecal cortisol metabolites. For males, fecal cortisol metabolites level during the mating season increased with the number of offspring produced and decreased with age.
Our study highlights the necessity of considering simultaneously seasonal fluctuations in GC level and the dynamics of stress reactivity in the study of life history and behavioral co-adaptations within natural populations.Start studying Behavioral Adaptations.

Scatter hoarding is a common means of temporary storage for seeds and bulbs. The small supplies, located throughout the home range, may later be eaten on the spot if perishable or consolidated in one of several large galleries in the burrow system of even in the underground nest.
A Behavioral Adaptation is something an animal does - how it acts usually in response to some type of external stimulus. Examples of behavioral adaptations: Migration-a seasonal movement of animals from one region to another. Hibernation-Hibernation is a deep sleep that helps them to save energy and survive the winter without eating much.

Structural and Behavioral Adaptations: All organisms have adaptations that help them survive and thrive. Some adaptations are structural. Structural adaptations are physical features of an organism like the bill on a bird or the fur on a bear.
Other adaptations are behavioral. Behavioral adaptations are the things organisms do to survive.
