Recreating biomes one label at a time

  1. 1. Recreating biomes one label at a time Katja C. Seltmann American Museum of Natural History
  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.
  3. 3. Historical Ecology What we grow up with today ends up as the baseline for our viewpoint of “nature” in the future.
  4. 4. Myzocallis (Myzocallis) castaneae Hemiptera have declining plant hosts Reuteria querci Telamona reclivata Platycotis vittata Atymna castaneaeAtymna querci Ophiderma flava Cyrtolobus maculifrontis Archasia auriculata Myzocallis (Neomyzocallis) punctata
  5. 5. Calculating host specificity
  6. 6. Role of natural history collections
  7. 7. Digitization of Hemiptera Present Dataset: Over 1,011,627 Total Specimens Date Range: 1811 – Present 124 total insect families Unique collecting events/ insect family
  8. 8. IUCN red list status 0.52% species of insects evaluated
  9. 9. Heteroptera have declining plant hosts IUCN Red List: Worldwide total plants: 345 81 plant species 322 Hemiptera species USDA Plants List: (Federally listed Endangered or Threatened) North American total plants: 752 31 plant species 127 Hemiptera species
  10. 10. Heteroptera have declining plant hosts Insect Plant 1 2
  11. 11. Conclusions 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. Future directions
