This folder contains the data file and R scripts necessary to model population growth rates (lambda) of a natural population, based on data from five transects from 2010-2012. Please contact Jill Anderson (jta24@uga.edu) with questions.

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

How climate change influences the dynamics of plant populations is not well understood, as few plant studies have measured responses of vital rates to climatic variables and modeled the impact on population growth. I used 25 years of demographic data to analyze how survival, growth, and fecundity re

Heritable genetic variation is necessary for populations to evolve in response to anthropogenic climate change. However, antagonistic genetic correlations among traits may constrain the rate of adaptation, even if substantial genetic variation exists. We examine potential genetic responses to select

Current understanding of reproduction for animal-pollinated plant species is based on the premise that traits of flowers and inflorescences influence reproductive success by affecting pollinator behavior. This implies that within-population variation in such traits should affect reproductive success

Pollen discounting, a reduction in success as an outcross pollen parent as a result of selfing, can reduce or eliminate the reproductive advantage commonly attributed to selfing. Previous estimates of pollen discounting have been based on segregation analysis of progeny from open-pollinated plants.

Behavioural adaptations to resource variability were examined in field experiments with least chipmunks, Tamias minimus, and golden-mantled ground squirrels and were predicted by a dynamic patch assessment model that weights patch information according to its reliability.

This overview of non-visual communication in freshwater benthic animals emphasizes recent studies of the effect of chemical and mechanical signals on predator-prey interactions of benthic macroinvertebrates and amphibians. Prey species use chemical signals to modify their morphological development,

A chronosequence study of permanent plots spanning 45 years on a 70-year-old subalpine earthflow in south-western Colorado suggests that it is the severe microclimate of the earthflow which is limiting further colonization of the site.

We studied the feeding and positioning periodicity on natural substrates of the overwintering and fast-growing summer generations of a grazing mayfly, Baetis bicaudatus, in a third-order trout stream and a fishless, first-order tributary in western Colorado. At 4-h intervals over 24-h, we recorded t
