We conducted a survey using a domestic rabbit (Oryctolagus cuniculus) as an alternative animal to Amami rabbit. We investigated the sizes of square gaps that could prevent a rabbit from entering an agricultural land. Three experimental sizes of square gaps were used as follows: four-squares (5.0×5.0 cm -15.0×15.0 cm at 2.5 cm intervals), vertically long rectangles (15.0 cm × 5.0-12.5 cm at 2.5 cm intervals), and horizontally long rectangles (5.0-12.5 cm × 15.0 cm at 2.5 cm intervals), and the minimum size of square gap that a rabbit could enter was the 7.5×7.5 cm four-square, 15.0×5.0 cm vertically long rectangle, and 7.5×15.0 cm horizontally long rectangle, respectively. According to our result, rabbit was able to enter into the narrower gap of vertically long rectangle more than that of the horizontally long rectangle. In conclusion, the length of one side of square gap that prevented a rabbit from entering an agricultural land was 5 cm for four-square, 5 cm for horizontally long rectangle, and less than 5 cm for vertically long rectangle.}, pages = {1--10}, title = {カイウサギが通り抜け出来ない方形枠のサイズは?}, volume = {71}, year = {2021} }
