Dr. Aldo Compagnoni


Research Interests


I am a population and community ecologist focusing on the response of plant populations to climate and biotic interactions. My past work addressed these themes using both experiments and analysis of long-term data.

Past work: During my dissertation, I investigated how warming and snowfall change the performance of Bromus tectorum, one of the most harmful plant invaders in North America. In my postdoc, I used long-term data sets to assess how life history characteristics modulate the effect of climate variability on long-term population growth rate.

My work on biotic interactions examined how competition and mating between the sexes balance to determine population level recruitment.

Currently, as part of the sApropos working group, I am investigating the life history determinants of species responses to climate. To achieve this aim, we are studying the effect of climate variability on the demographic fluctuations of a wide variety of plant taxa.
