Rodents are notable for their unique life history traits that render a fast-breeding capacity.
Their short generation times allow local adaptations to appear, and several studies have …

Background Species adjust to changes in temperature and the accompanying reduction in
resource availability during the annual cycle by shifts in energy allocation. As it gets colder …

In mammals, birth mass is an important predictor of early growth and survival. Within litters,
heavier siblings are usually able to outcompete smaller siblings and gain more resources …

Life-history trade-offs are predicted to contribute to the maintenance of personality variation.
Individuals with 'fast'lifestyles should develop faster, reproduce earlier and exhibit more risky …

Species following a fast life history are expected to express fitness costs mainly as increased
mortality, while slow‐lived species should suffer fertility costs. Because observational …

Seasonality influences behaviour, physiology and life history of organisms, and photoperiod
is a reliable and influential cue gearing individual adaptation to seasonal changes in the …

Simple Summary Inbred strains of guinea pigs are a vital resource in the study of human
disease and infection. However, maintenance of these colonies can be challenging due to …

Environmental variation strongly influences individual life histories, behavior, and immunity.
For many animals living in non-tropical regions, environmental variation due to season is …

To survive and reproduce successfully, animals have to find the optimal time of breeding.
Species living in nontropical environments often adjust their reproduction plastically …

The domesticated guinea pig, Cavia porcellus, has a long and rich history in laboratory
research. This history is in part because the docile rodent shares many biobehavioral …
