Sexes in sync: phenotypic plasticity, sexual selection and phenological synchrony between the sexes in a wild hibernator.

Desynchrony of phenological responses to climate change is a major concern for ecological communities. Potential uncoupling between one of the most fundamental divisions within populations, males and females, has not been well studied. To address this gap, we examined sex-specific plasticity in hibernation phenology in two populations of Columbian ground squirrels ().

Parental investment in the Columbian ground squirrel: empirical tests of sex allocation models.

Parental allocation of resources into male or female offspring and differences in the balance of offspring sexes in natural populations are central research topics in evolutionary ecology. Fisher (Fisher, R. A.

Preliminary codesign and testing of a feedback tool to improve the quality of peer appraiser documentation for medical revalidation.

Medical appraisal and associated revalidation are mandatory for doctors in the United Kingdom. However, the quality of appraisal documentation, which informs the revalidation process on a doctor's fitness-to-practise, is known to be variable. This preliminary study aimed to develop and test a formative educational tool that could be used, as part of routine appraiser training in the general practice setting, to review and provide evidence and feedback on the quality of documentation completion.

Testing the reproductive and somatic trade-off in female Columbian ground squirrels.

Energetic trade-offs in resource allocation form the basis of life-history theory, which predicts that reproductive allocation in a given season should negatively affect future reproduction or individual survival. We examined how allocation of resources differed between successful and unsuccessful breeding female Columbian ground squirrels to discern any effects of resource allocation on reproductive and somatic efforts. We compared the survival rates, subsequent reprodction, and mass gain of successful breeders (females that successfully weaned young) and unsuccessful breeders (females that failed to give birth or wean young) and investigated "carryover" effects to the next year.

Fitness implications of seasonal climate variation in Columbian ground squirrels.

The influence of climate change on the fitness of wild populations is often studied in the context of the spring onset of the reproductive season. This focus is relevant for climate influences on reproductive success, but neglects other fitness-relevant periods (e.g.
