By adopting the dynamic panel threshold approach, this study assesses how foreign direct investment (FDI) shapes the causality between urbanization and CO₂ emissions in China from 1996–2018. The results suggest that a rise in the pace of urbanization increases CO₂ emissions, but this harmful effect becomes weaker after achieving a certain level of foreign capital. We also find that the more developed the technology, financial and government sectors, the more it can promote urbanization to reduce CO₂ emissions. These results offer policy implications for China’s urban planning and environmental policy.

Although the GDP of the fishery sector accounts for less than 0.3% of Taiwan’s GDP, there are many secondary and tertiary industries related to fisheries that add great value to the country’s economy. Therefore, when analyzing and calculating the output value and value added of the fishery sector, the relevance of these upstream and downstream industries should be considered jointly, and the value chain of the fishery industry should be studied and analyzed in order to truly present the value added created by fishery. This study aims to do this by first analyzing not only the primary fishery industry, but the value chain of the fishery industry at different stages such as fishery production, marine fishing, aquaculture, fishery processing, retail and services, and supportive systems. Then the value added of the whole fishery value chain to Taiwan’s GDP is estimated by using the Leontief input–output model, from the perspective of industry linkages and covering the period from 2011 to 2018. The empirical results suggest that the value added created by fishery and related industries accounted for 2.96% of the GDP in 2011, which rose to 3.11% in 2014, fell to 2.87% in 2015, rose to 2.93% in 2017, and fell to 2.84% in 2018. From 2011 to 2018, the amount of value added created by fisheries and related industries rose from NT$ 422.8 billion to NT$ 520.9 billion. The primary fishery sector has the largest contribution, followed by the fishery input sector, and transportation and sale service sector, and the fishery product processing sector has the lowest contribution rate. The empirical results provide important implications and references to the policy makers.

A new species, Stemonosudis adenensissp. nov., of slender barracudina is described based on a specimen collected off Somalia, Western Indian Ocean. The new species differs from its congeners by having a uniformly brown body, without distinct black patches; nostrils slightly before the posterior end of the maxilla; anus above the tip of the appressed pelvic fin; lateral-line scales: prepelvic 39, predorsal 48, preanal 59, total 81; vertebrae: prepelvic 38, prehaemal 42, predorsal 46, preanal 59, caudal 53, and total 95; and total gill rakers 68. Additional records of Stemonosudis siliquiventer Post, 1970 from the Caribbean Sea are also provided.
