Using the climbing ability of Bufo bankorensis and Hynobius arisanensis to discuss the amphibious corridor design for high altitude areas

Abstract

In recent years, as Taiwan’s environmental development density continuously increases, the adverse effect on ecology grows increasingly, especially the effect of mountain waterfront artificial facilities on amphibians. This study measures the body weight and body length of Bufo bankorensis and Hynobius arisanensis, and uses different climatic conditions of side slope matrix, angle, ambient temperature, and humidity to research the differences in climbing ability, and attempts to determine the optimum design model of an amphibious corridor. The findings show that the average weight and body length of Bufo bankorensis are greater than Hynobius arisanensis, where the body weight difference is 33 times and the body length difference is 3.29cm. Hynobius arisanensis has better climbing ability per unit body weight than Bufo bankorensis. Hynobius arisanensis has the best climbing ability on a grass matrix. Generally speaking, the optimum environments for Bufo bankorensis are Clay>Grass>Concrete>Wood>Cobblestone; while the optimum environments for Hynobius arisanensis are Grass>Clay>Cobblestone>Wood>Concrete. This study is expected to provide useful reference for future high mountain area waterfront designers.
