Demography of species of conservation concern

Collaborators:
Christine Hunter,  Stephanie Jenouvrier, Richard Lawler, Carly Strasser

Conservation is, in essence, a demographic problem. There is no endangered species that could not be transformed into a pest species by the application of a little positive exponential growth. Hence, understanding the growth potential, the factors that limit it, and the potential of management actions to influence it, are critical to conservation. My laboratory has a long tradition of producing demographic analysis of threatened or endangered species. I look for cases that are likely to lead to new theoretical or analytical developments, and where collaborators with interesting data sets can be found. Recent examples include
  • the North Atlantic right whale
  • the polar bear
  • Verreaux's sifaka (a lemur; really cute)
  • the emperor penguin
  • several species of albatrosses and other seabirds
  • endangered terrestrial plants, including Boltonia decurrens in the flood plain of the Illinois River, and Lomatium bradshawii in prairies in Oregon.
Recently, these projects have developed a focus on effects of climate change, described here as another project.
