Community ecology in 3D: Tensor decomposition reveals spatio-temporal dynamics of large ecological communities
Fig 1
Presentation of the data set and its multidimensional nature.
(A) Community data represented as a three-dimensional tensor. Each pixel represents the abundance level (relative to the average abundance of each species in the survey) of the fish species in the North Sea in its 3 dimensions: species, time and space. (B) Map of the study area showing the 7 predefined areas (called roundfish areas) which serve as the spatial scale of our study.
