Over the last three decades, the threat to amphibian animals has become more and more serious. Especially, the loss of natural habitats caused by changes to the way land is used by human beings. This issue has hit amphibians extraordinarily hard. Moreover, it is known that amphibians are particularly vulnerable to human activities because they rely on both terrestrial and aquatic habitats for survival. Due to increased development in many areas, concrete structures are often built along water bodies in order to increase the safety of structures. The development of solid banks along streams related with human improvement has become a major issue in Taiwan. Most ecosystems used by amphibians are lakes, ponds, rivers and stream banks. However, there is no related design solution to accommodate the needs of those amphibians. The need to develop the relevant design specification considering protecting the amphibian is very urgent. The objectives of this study were to investigate (1) the relationships between the physical characteristics and climbing ability of toads, (2) whether statistics analysis can be can be utilized to improve the understandings of the actual attributes of amphibian, (3) whether Artificial Neural Network can be used to simulate the climbing ability of toad. The experimental and numerical results showed that there is a strong positive correlation between physical characteristics and climbing ability of toads.

In 2019, the degree of food self-support in Taiwan was 32.08%, which was lower than that in the previous year by 2.4%. Taiwan does not have the ability to control the availability of food in the face of a food crisis. This study used an aquaponics system to implement the mutualism of fish, flowers, vegetables, and water, as well as to implement the cyclic utilization of water, so that vegetables and fruit could be produced to relieve food shortages in the world. The simulation site of this study was located on a gentle grassy slope alongside Li-tze Lake in Changhua County, Taiwan. In the simulation, three light-tight experimental buckets, with an upper rim diameter of 130 cm, a bottom rim diameter of 125 cm, and a height of 180 cm, were embedded in the ground. The target vegetables and flowers were planted in pots at 17 cm apart, and they were planted on the water surface using the floating island principle. A solar power system enabled a motorized pump to irrigate the plants. An aerator provided adequate aeration to achieve an elementary purifying effect. The experimental results showed that, in terms of the dissolved oxygen, the mean difference of the experimental group was about 1 mg/L, that of the control group was 2 mg/L, and the maximum difference was 6.5 mg/L. As the fish died in April, the ammonia nitrogen value of the control group was 68 times higher than that of the experimental group. Due to the nitrification in July, the ammonia nitrogen decomposed into NO2, which suddenly increased to 13 mg/L and was extremely unsuitable for the existence of aquatic organisms. This amount was five to six times higher than that of the experimental group. In terms of the fish growth rate, the control group could not bear the drastic changes in the water body at the intermediate stage, and all the fish died, whereas the fish in the experimental group were not affected. The results of this study could provide useful data for gardening, aquatic products, and space design staff.

Environmental protection is an important issue in modern society. Most construction demolition wastes cannot be easily decomposed, thus occupying a lot of space in landfill. Reducing the demand for new resources is an efficient approach to decrease the environmental burden. Most green buildings are made from reused and recycled materials. Although there are a variety of green building materials available on the market, there is no material, as yet, with thermochromic functionality. This study used a form of face bricks, and six recovered materials, including wood chips, iron powder, fallen leaves, concrete, newspaper, and silt, to make smart green building materials. The modules were made in accordance with Taiwan’s green building material regulations. The discoloration efficiency of indoor and outdoor green building materials was tested, and the RGB (red, green, blue) values of the face bricks were measured by a color analyzer to observe the discoloration effect. The findings show that among the A, B, C, and D groups, Group D exhibited the optimal rate of change in color, and the rates of change in the six recycled waste materials of indoor Group D were wood chips > newspaper > fallen leaves > concrete > iron powder > silt, while the rates of change in the outdoor group were newspaper > wood chips > fallen leaves. This study successfully reused waste materials to reduce the environmental burden, achieve sustainable environmental protection, and ensure both the aesthetics and quality of the building materials. The results of this study can offer an alternative choice to architects or space designers when selecting green building materials.

Current excessive environmental developments result in a growing number of artificial facilities, and the impact of human activities leads to the destruction and loss of many natural habitats, while the remaining habitats are isolated and fragmented, and are increasingly replaced by more artificial facilities. Today’s agriculture in Taiwan generally adopts pesticides and other means of farming, and the government encourages the use of cement as a ridge. Although a cement ridge can be easily used by farmers, will reduce the amount of weeds, and improve agricultural production, its environmental costs may be higher. Therefore, this study mainly probes into the differences in ecological abundance between organic farms with a mud ridge and conventional farms with a cement ridge. This study employs field investigation, records the species found by camera, and observes and analyzes the abundance and the relationship between the growth and decline of the species in these two different environments. According to the research results, biological species occur throughout the year; however, the numbers of species in organic farms are nearly 3 times higher than that of conventional farms: 7 more types of insects, 1 more type of arachnid, and 7 more types of birds, and the number of a single species is 20 times higher. This study can be used as a reference and basis for engaging in agricultural production and planning farming areas when considering environmental and ecological conservation in the future.

Artificial Floating Islands (AFIs) are human-made floating structures capable of supporting aquatic vegetation. Previous studies pointed out that most AFIs use aquatic plants to carry out improvement of water quality and ecological conservation. This study proposed a modified AFI system, named Green Water Farm (GWF), to increase the practical application value of traditional AFIs, and added a special design to create an environment that allows for terrestrial plants (including vegetables and flowers) to grow and to carry out improvement of water quality and ecological conservation. The research site was located at the waterfront of Li-tze Lake in Pitou Township, Taiwan. A GWF was established to evaluate the improvement of water quality and ecological conservation. During one year, water quality and ecological conservation assessments were recorded to investigate the performance of GWF system. The research results showed that GWF could improve water quality and ecological conservation. In addition, the results of this study can provide useful information for more food sources for humans and animals, and increase biodiversity and ecological conservation.

Because of thriving tourism in recent years, concrete constructions have been installed by creeks in order to protect the safety of tourists, but the effect of concrete structures on the habitats and the mobility of certain species is still unknown. This study evaluates the different effects of various water bank substrates in terms of the influence on Hynobius arisanensis's (Maki) motility in Alishan National Park. Comparing the concrete area with two other areas where primitive streams flow by, it was observed that concrete structures lead to increased flow velocities, shallower water depths and poorer water quality. In the biological motility assessment, moss, rock, wood, clay and concrete as distinct water bank substrates were used to test the climbing ability of H. arisanensis. Based on the seasonal humidity changes in winter and summer of Alishan area, H. arisanensis's climbing ability was tested in two conditions, high humidity/high temperature and high humidity/low temperature. It was determined that climbing ability dropped rapidly with increasing slope angles. It was observed that the climbing ability of H. arisanensis is slightly decreased in low temperature. Regarding the upper limit of design slope suitable for H. arisanensis are: wood and concrete are ≤45°, moss surface ≤60° and clay surface ≤30°. The results here can provide insights for future engineering projects on creek banks to benefit H. arisanensis conservation.
