台湾短低温桃品种种性研究

2000年引进台湾4个短低温桃品种进行了种性研究,结果表明:供试品种需冷量少,坐果率极高,丰产性好,抗病性强,适合在闽东、中、南高湿多湿区域栽培,但其品质与市场要求存在一定差距,莺歌桃风味偏酸,台脆桃、福寿桃、甜蜜桃果实偏小,暂不适宜大规模发展。     

Age, growth, and reproduction of silky sharks, Carcharhinus falciformis, in northeastern Taiwan waters

To examine the age, growth and reproduction of silky sharks, Carcharhinus falciformis, in the waters off northeastern Taiwan, 469 specimens (213 females and 256 males) were collected from August 2000 to January 2002 at the Nanfanao fish market, northeastern Taiwan. The relationship between body weight (W) and total length (TL) for both sexes combined was expressed as: W = 2.92 × 10⁻⁶ TL^3.15 (n = 469, p < 0.01). The relationship between TL and vertebral centrum radius (R) for both sexes combined data was estimated as: TL = 25.979 + 18.197R (n = 250, p < 0.01). Growth bands (including translucent and opaque zones) in precaudal vertebrae formed once a year between December and January and were counted up to 11 and 14 for females and males, respectively. The von Bertalanffy growth function (VBGF) was used to model the observed length at age data. The sexes combined VBGF predicted an asymptotic length (L_∞) = 332.0 cm TL, growth coefficient (k) = 0.0838 year⁻¹, age at zero length (t₀) = −2.761 year (n = 250, p < 0.01). Size at 50% maturity for males was estimated to be 212.5 cm based on the logistic curve, which corresponded to 9.3 years. Females matured at 210–220 cm, which correspond to 9.2–10.2 years. The length at birth was estimated to be 63.5–75.5 cm TL. The number of embryos per litter was 8–10 and sex ratio of embryos was 1:1.     

Geopolitical multiculturalism in East Asia

In this research note, I expand the discussion on multicultural policies in East Asia by proposing the concept of ‘geopolitical multiculturalism’. It describes that the receiving state promotes multiculturalism or pro-immigrant programmes and discourses to enhance the nation's global standing, regional importance, economic development, and geopolitical security. East Asian countries serve as illustrative examples of this concept, as their substantial immigrant populations are relatively recent, and the development of multicultural programmes is closely tied to international influence. I will first elaborate on three approaches to geopolitical multiculturalism, followed by a detailed analysis of Taiwan's case, including the recent implementation of the New Southbound Policy. I draw conclusions regarding the implications and potential applications of this concept for future research.
