He discussed various theoretical aspects, including a number of earlier attempts at defining expressive behavior unequivocally, and formulated the following definition of his own:作者: Cursory 時間: 2025-3-23 19:43

Relations with Animals of Other Speciescan very broadly categorize such relations—from the point of view of the ungulate—as positive, neutral, or negative. A relationship is positive when the ungulate involved derives some benefit from the association or interaction.
