For the past few years sambar in Yushan National Park have been found gnawing bark off trees, sometimes “girdling” the entire tree by gnawing the bark along its entire circumference, cutting off the transmission of nutrients and killing the tree. The park administration opened up an investigation into the problem. Preliminary findings point to the sambar needing calcium for the growth of their antlers, and stripping the tree bark to supplement the nutrient. The exact reason for this still requires further analysis. Future research will also look into how to address the problem, and how to avoid trees dying because their bark is being stripped, altering the forest physiognomy and ecology.
The park administration says it has been investigating the problem of sambar gnawing tree bark along the Nanzih Siansi Forest Road in the park area. Research focusing on the Red Cypress coniferous trees has discovered that the gnawing occurs mostly between March and May, during the spring.
This period, between March and May, coincides with the time the antlers of the park’s sambars are hardening. It is at this time that they need calcium, and this nutrient is found in the bark of the Red Cypress coniferous trees. It is thought that the sambars are gnawing the bark to obtain calcium. To protect the trees in the park, animal salt blocks are being placed in the area, to provide for the sambars’ nutritional needs. It is hoped that this measure will reduce the bark stripping.

Another investigation has been taking place in the Tataka area of the park over the past few years. The initial findings of this investigation is that the bark gnawing is occurring in the period from May through November, mostly in the summer and fall, different from the time in the Nanzih Siansi Forest Road area.
In the future, the height above sea level and the forest physiognomy of the two areas will be compared, to clarify what is producing the different bark gnawing behavior. This could be because the sambar herds are migrating through the areas. This information will be used as a reference for future forest conservation efforts.

Chinese automobile manufacturer Zotye Auto is a household name in China. The company is famous for manufacturing copies of car models by luxury international brands including Audi, Porsche and Lamborghini. After a long delay, on June 22, Zotye Auto finally released its 2019 year end financial results. The report revealed that last year, the automaker suffered losses of 11.2 billion yuan (approximately NT$46.6 billion), or an average of 30 million yuan per day. The company’s market value also shrank from 30 billion yuan to a mere 3.6 billion yuan. Even worse, because the company is unable to guarantee the authenticity,
Onions, with their sweet aroma, are a popular cooking ingredient, used in both Western and Eastern cuisines. Today, however, information is appearing online suggesting that onions should not be eaten with fish, shrimp, seaweed or honey, as these combinations cause kidney stones. But is there any truth to this? The Taiwan FactCheck Center asked dieticians and experts and confirmed that this information was false. Onion loving foodies everywhere can breathe a sigh of relief. According to information on certain social media platforms, onions should not be eaten together with fish, as the fish has a high protein content, and the oxalic
Pluto, a frigid little world inhabiting the solar system’s outer reaches, may have been born as a warmer place sheltering a subsurface ocean that still exists today, researchers said on Monday. An analysis of images of its surface taken in 2015 by NASA’s New Horizons spacecraft and computer simulations of the dwarf planet’s interior led the researchers to propose a “hot start” scenario for Pluto’s formation some 4.5 billion years ago as the solar system, including Earth, took shape. “When Pluto was forming, new material would have been coming in and impacting its surface. Each impact is like an explosion that
Segway Inc. announced last week that it will end production of its iconic two-wheeled personal vehicle starting July 15. When the company launched the product nearly two decades ago, it boldly claimed that its namesake two-wheeler would revolutionize the way people move, but it only sold 140,000 units across the world. The Segway was criticized for the high price tag of US$4,950 (about NT$147,000). It was also challenging to ride, because riders must maintain a balance at a specific angle for the vehicle to move forward, and can easily be thrown off if they lose control. Several months after buying the
