The fate of natural populations is mediated by complex interactions among vital rates, which can vary within and among years. While the effects of random, among-year variation in vital rates have been studied extensively, relatively little is known about how periodic, non-random variation in vital r

These R scripts contain the code to replicate the analyses performed in Demographic consequences of changing environmental periodicity , Ecology. Vital-rate estimation We used the demographic data of each species to model periodic differences in vital rates for each life-cycle stage using generalize

Animals are often confronted with potentially informative stimuli from a variety of sensory modalities. While there is a large proximate literature demonstrating multisensory integration, no general framework explains why animals integrate. We developed and tested a quantitative model that explains

This data file contains a matrix of genetic kinship for the 43 individual marmots analyzed in this study. Kinship was calculated as pair-wise relatedness between individuals based on genotypes taken from 12 microsatellite loci (detailed genotyping methods described in Blumstein et al. 2010 doi:10.11

This data file contains trait information concerning the 43 individual marmots, or their blood samples (one per individual), analyzed in this study. Much of the data was collected in the field (e.g., sex, dispersal status), whereas other data were collected in the lab (e.g., RIN score, cell counts).

The cumulative cost of reproduction hypothesis predicts that reproductive costs accumulate over an individual’s reproductive lifespan. While short-term costs have been extensively explored, the prevalence of cumulative long-term costs and the circumstances under which such costs occur alongside or i

Humans in strong social relationships are more likely to live longer because social relationships may buffer stressors and thus have protective effects. However, a shortcoming of human studies is that they often rely on self-reporting of these relationships. By contrast, observational studies of non
