Abstract:

Data is from Tarnecki, J.H., Wallace, A., Simons, J. and Ainsworth, C.H. 2016. Progression of a Gulf of Mexico Food Web Supporting Atlantis Ecosystem Model Development. Fisheries Research (doi:10.1016/j.fishres.2016.02.023). This is a dataset representing predator-prey linkages with associated error ranges for Gulf of Mexico fish functional groups. The data will be used in an Atlantis biogeochemical trophic ecosystem model of the Gulf of Mexico described by Ainsworth et al. 2015 (NOAA Technical Memorandum NMFS-SEFSC-676). This diet dataset is based on data previously published in Masi, M.D., Ainsworth, C.H., Chagaris, D., 2014. (Ecol. Model. 284, 60-74) and expanded to include new original stomach sampling described by Tarnecki et al., as well as information collated in the Gulf of Mexico Species Interaction Database (GoMexSI) maintained by Jim Simons at Texas A&M Corpus Christi. The main improvement over the original Masi et al. diet matrix is that more species are considered and from a wider geographic range (including waters of the western Gulf of Mexico). Tarnecki et al use this improved diet matrix in Atlantis to show improved model performance; they also compared this revised diet matrix against previously published diet matrices for the Gulf of Mexico. The format of this data is similar to the original Masi et al. diet data located here: http://dx.doi.org/10.7266/N7Q23X72 (UDI: R1.x135.120:0007).
