Classification of the input data (number of individuals: 113 species × 2 cultivation methods × 36 surveys) using the self-organizing map. (a) 42 output neurons arranged in a two-dimensional grid (7 × 6). (b) Neurons grouped into four clusters, which are shown in different colors, using dendrograms produced using Ward’s linkage method. V1-V42 indicate each output neuron (hexagon unit). The circles in the neurons indicate the input data, which are the bird communities observed in two areas by cultivation method during 36 surveys periods.
