Biology - Diet

[RGamble1]

• Ensure meaningful diet contributions for major predators
• Ensure overlap in space/time of expected matchups

Issues:
currently squid-heavy diets for many, including apex preds
ANC, HER not represented well as primary diet item for predators (but often in ‘rest’)
HAL adult primary pred not sharks but HAD
SHK & WHK primary predators for many large fish (some OK)

[RGamble1]

ToDo:
Adjust pPrey as required (in process)
Adjusted vertday_XXX vertnight_XXX to see if matchups in space/time different

Testing diets
Scaled increase availability of all vertebrate (only) to other vertebrates:
20191001dtb - 1st iteration
20191001dtd - 2nd pass through scalar function

Reduce availability of BFF and BG to heavy vertebrate consumers:
20190930dtc

Reduce availability of invertebrates to vertebrates:
20190924dtb

[RGamble1]

• Create diet data file for species/groups in Atlantis from 2001 - 2010
  • Create R script for gathering and apportioning the diet
  • Compare results from R script to Brian Smith's original code
