  2. 2. Human-mediated Disturbance Our great loss in biodiversity that is difficult to calculate. Many efforts exist to sample a snapshot of present biodiversity as the world is rapidly changing from increased human activity. enicospilus@gmail.com
  3. 3. Historical Ecology What we grow up with today ends up as the baseline for our viewpoint of “nature” in the future. enicospilus@gmail.com

Conclusions enicospilus@gmail.com 0.0 0.2 0.4 0.6 0.8 1.0 0246810 p(x|y) #InsectSpecies red-listed not red-listed In this dataset (31 hemipteran species collected from USDA red- listed plants and all of their other known hosts) there is a higher probability that the insect was collected on a red-listed host than non red-listed. 19 species have a > 10% probability that they were collected on a federally Endangered or Threatened Plant. 9 species are only known to be collected on a red-listed species.
  12. 12. • Continue to explore new methods for examining this data (Data Science: Ontology & Machine Learning). – Explore data bias of collectors by adding Collector into the equation of p(x|Y). – Include a third trophic level (parasitoids) into the data analysis. – Expand to world plant host list and other insect records outside of Hemiptera. – Include known phylogenies of insect and plant.
