Chun-Wei Chang and Chih-hao Hsieh Prof. Chih-hao Hsieh from the Institute of Oceanography and Prof. Chun-Wei Chang from the Institute of Fishery Sciences, NTU lead an international team and develop a novel method that successfully anticipates the occurrence and type of a variety of critical transition events. This study, published in Science Advances (Jan 2023), overcomes the long-lasting challenge in revealing a quantitative threshold as well as distinguishing types of critical transition by early warning signals using empirical data collected in real-world systems. The proposed method also provides a powerful…

Europe, even located at the mid-high latitude at 40-70oN, the autumn and winter are mild and comfortable. Such pleasant weather is regulated by the warm and humid westerly winds from the North Atlantic Ocean. During the 15th to 19th century, Europe experienced the coldest winters over the last ten thousand years, known as the “Little Ice Age” (LIA). The LIA was suggested to be caused by volcanic eruptions and low solar activity. However, the detailed climate pattern in Europe remains unclear.Dr. Hsun-Ming Hu, the first author, and Prof. Chuan-Chou Shen,…

Causal networks of phytoplankton diversity and biomass are modulated by environmental context Chun-Wei Chang and Chih-hao Hsieh Postdoctoral fellow, Dr. Chun-Wei Chang, from the National Center for Theoretical Sciences and Prof. Chih-hao Hsieh from the Institute of Oceanography, NTU lead an international research team and analyze aquatic ecosystems (ranging from lake, river to estuary and ocean) around the world to unveil key causal interactions and feedbacks between biodiversity, ecosystem functions, and various environmental factors. This study, published in Nature Communications (March 3, 2022), overcomes the long-lasting challenge in quantifying complex…

Profs. Chun-Mao Tseng and Jen-Chieh Shiao from the Institute of Oceanography, NTU, and the US cooperative colleagues worked together as the mercury research team (referred to Team Mercury (Hg) hereinafter). The research provides them to initiate a new tool of the mercury accumulation rate (MAR) using top predators to examine global patterns in the cycling and pollution of Hg across the world's oceans. It also confirms the unchanging truth of "You are what you eat, and You have what you are" since time began. The results of this study, published…

The National Taiwan University has, in an international team effort, collaborated with the Chinese Culture University, the University of Taipei, the National University of Singapore, the Royal Melbourne Institute of Technology, and the Tokyo Institute of Technology, to write a review article on the physics of Yang-Mills in spintronics. This article was recently published in the Physics Reports (Oct 2020). Physics Reports has always been one of the academic journals with the highest impact factor in physics community. The 5-Year Impact Factor is 24.659, which is much higher than the…

NTU oceanographer and international team discovered ongoing and future tropical diversity decline Source：Services for Media, HKU How can patterns in the marine biodiversity of the past help us to understand how it may change in the future? A recent research by Drs Moriaki Yasuhara (School of Biological Sciences and Swire Institute of Marine Science, The University of Hong Kong), Chih-Lin Wei (Institute of Oceanography, National Taiwan University) and numerous international collaborators finds that the tropical diversity decline now seen in the ocean is not purely human induced, but nonetheless will…
