SEUS MBON Zooplankton dataset comparisons #10

Open 7yl4r opened 1 year ago

7yl4r commented 1 year ago

There are three sources of Zooplankton from the SEUS MBON research cruises:

  1. Jaime's microscopy
  2. Natalia's microscopy
  3. Anni's eDNA

Digna has done comparison of Jaime's & Natalia's datasets. Some notable facts for the datasets:

  1. Jaime's has more species+genus level taxa - especially with copepods.
  2. The number of samples analyzed for Jaime & Natalia are similar for mesh sizes 200+500, but Natalia's dataset has very few analyzed for the 64 mesh size.
  3. ~12 full samples at different mesh sizes for different times of years were overlapped between the two datasets.

open questions

  1. how do we compare datasets with subjective taxa bias
  2. what is the taxa level that two datasets can be effectively compared at?
  3. what generalized recommendation can be we make for future data collection efforts?
  4. can we use network analysis methods to compare occurrence datasets as weighted taxa trees of occurrences?
