Much to the excitement of marine ecologists, new coral reefs have been discovered in Shanyuan Bay (
"The Shanyuan Bay coral reefs span a broad area of water and contain a wide diversity of coral strains," said Chen Chao-lun (陳昭倫), an associate researcher at Academia Sinica's Research Center for Biodiversity.
"Coral communities can be found in waters 1km off the coastline at a depth of 8m to 10m," Chen said, adding that the coral reef located closest to the coast is only 50m away from the shore.
Chen surveyed waters in Shanyuan Bay earlier this month as part of a study of coral reef habitats in eastern coastal regions.
He recorded 110 coral strains, roughly one-third the total number of species documented in Taiwanese waters. Among them, 94 were stone corals, 11 were soft corals and five were polyp corals.
"The number indicates that Shanyuan Bay's coral diversity is similar to that around Green Island," Chen said.
Shanyuan Bay, just off the coast from Taitung City, also boasts a dense and diverse cornularia coral community in which a wealth of fish, shrimp and shell species live, a phenomenon not seen in the Kenting and Green Island areas, Chen said.
A mature, well-developed polyp coral community also exists in 3m to 5m-deep waters in the bay, another rarity for Taiwan, Chen said.
Most encouraging was that a stem of Oulophyllia bennetthae coral was discovered in the bay, Chen said, adding that it marked the first time that the coral strain normally seen in the Indian Ocean had been recorded in Taiwanese waters.
"Although this coral species is spread over a wide area, the frequency of its appearance is very low," Chen said, adding that the existence of the 1m high, 60cm-wide coral underscores the diversity to be found in Taiwan's coral communities.
Chen's study coincides with a UN global coral reefs survey, as this year has been designated the International Year of Reefs to enhance public awareness of the importance of protecting coral reefs and their ecosystems.
Chen said he was impressed by the special coral reef ecological scenes beneath Shanyuan Bay, with various kinds of soft corals growing on large reefs.
"Its beauty and biodiversity rival those found in the Kenting area more than 10 years ago and can even compare with those found off Green Island and Orchid Island," Chen said.
With a five-story holiday resort sitting on the bay's left bank, Chen said he is worried that the coral reefs in the region could face a fate similar to those in the Kenting area.
Chen urged relevant government agencies to take immediate steps to better manage and protect the Shanyuan Bay coral reefs.
Theaters and institutions in Taiwan have received 28 threatening e-mails, including bomb threats, since a documentary critical of China began being screened across the nation last month, the National Security Bureau said yesterday. The actions are part of China’s attempts to undermine Taiwan’s sovereignty, it said. State Organs (國有器官) documents allegations that Chinese government officials engage in organ harvesting and other illegal activities. From last month to Friday last week, 28 incidents have been reported of theaters or institutions receiving threats, including bomb and shooting threats, if they did not stop showing the documentary, the bureau said. Although the threats were not carried out,
The Mainland Affairs Council (MAC) on Friday condemned Chinese and Russian authorities for escalating regional tensions, citing Chinese warplanes crossing the Taiwan Strait’s median line and joint China-Russia military activities breaching South Korea’s air defense identification zone (KADIZ) over the past two days. A total of 30 Chinese warplanes crossed the median line of the Taiwan Strait on Thursday and Friday, entering Taiwan’s northern and southwestern airspace in coordination with 15 naval vessels and three high-altitude balloons, the MAC said in a statement. The Chinese military also carried out another “joint combat readiness patrol” targeting Taiwan on Thursday evening, the MAC said. On
The Mainland Affairs Council (MAC) yesterday confirmed that Chinese students visiting Taiwan at the invitation of the Ma Ying-jeou Foundation were almost all affiliated with the Chinese Communist Party (CCP). During yesterday’s meeting convened by the legislature’s Foreign Affairs and National Defense Committee, Democratic Progressive Party (DPP) Legislator Michelle Lin (林楚茵) asked whether the visit was a way to spread China’s so-called “united front” rhetoric, to which MAC Deputy Ministry Shen You-chung (沈有忠) responded with the CCP comment. The MAC noticed that the Chinese individuals visiting Taiwan, including those in sports, education, or religion, have had increasingly impressive backgrounds, demonstrating that the
MILITARY EXERCISES: China is expected to conduct more drills in the region after President William Lai’s office announced he would stopover in Hawaii and Guam China is likely to launch military drills in the coming days near Taiwan, using President William Lai’s (賴清德) upcoming trip to the Pacific and scheduled US transit as a pretext, regional security officials said. Lai is to begin a visit to Taipei’s three diplomatic allies in the Pacific on Saturday, and sources told Reuters he was planning stops in Hawaii and the US territory of Guam in a sensitive trip shortly after the US presidential election. Lai’s office has yet to confirm details of what are officially “stop-overs” in the US, but is expected to do so shortly before he departs, sources
