A lesson from Bass Strait on connectivity conservation

Isolation effects on the distributions of plant species in fragmented forests appear to be weak over tens to hundreds of years and strong over geological eras. The 250 km wide, 6.5 millennia old Bass Strait, and other millennium-scale disjunctions in the range of Eucalyptus regnans forests, were used to determine the effects of intermediate periods of isolation on plant species occurrence and composition. Three of six floristic communities were found on both sides of Bass Strait. The residuals from multiple regression models using climatic variables on the latitude vector were not explained by latitude, indicating negligible isolation effects from Bass Strait. However, there was a lesser compositional effect of disjunctions within land masses than between land masses, suggesting some effect of the larger barrier. No species that commonly occurred with E. regnans and were largely confined to wet forest exhibited absences from any region where the climate and soils were within their range. If areas isolated from each other for millennia can maintain their vascular plant biota, the expenditure of conservation funds on creating corridors to connect large areas separated by anthropogenic landscape modification might require more justification than it is currently afforded.     

Study on the strontium isotope standard in pig teeth excavated from Zaoshugounao site,Shaanxi Province of China

In archaeology, strontium isotope analysis is developing into an efficient scientific technique for tracing the movement of prehistoric humans and animals. Determining the local bioavailable ⁸⁷Sr/⁸⁶Sr ratio range is the key to distinguishing whether the human or animal is indigenous to the local area. It has been shown that the ⁸⁷Sr/⁸⁶Sr ratio in the enamel of pigs can be an excellent sample to determine the range of local strontium isotope ratio at the site. However, pigs may not be all local at the site, and there is no special study on whether pigs’ different ages and tooth types impact the local strontium isotope characteristics. In this paper, the tooth enamel of 19 pigs from the Zaoshugounao site for strontium isotope ratio (⁸⁷Sr/⁸⁶Sr) by multicollector–inductively coupled plasma mass spectrometry. There were no significant differences in ⁸⁷Sr/⁸⁶Sr ratios of local pigs at different months and different molar types, which did not affect the determination of the local strontium isotope standard. Based on the local strontium isotope ratio range (0.711056–0.711476), we found that five pigs were non-local. The Jing and Wei river basins (in Guanzhong basin) and northern Shaanxi are likely sources of non-pigs.

媒人现象的社会作用及其演变

媒人是历史发展中的特殊民俗现象,也是一种特定的文化符号。媒人随一夫一妻制的聘娶婚的出现而出现,在防止男女乱性、保障婚姻安全、完善规范礼法等方面起着积极的历史作用。媒人不仅不会退出历史舞台,相反,在新的历史时期,媒人的社会作用将更加彰显。     

浙江省平湖庄桥坟遗址出土石犁的保护修复

浙江平湖庄桥坟遗址出土的石犁是史前考古的新发现,属于痕迹文物。出土时木构件痕迹饱水,为暗褐色、开裂严重、整体呈腐蚀状,非常脆弱。针对器物的保存状况,因地制宜地制定一系列保护方法:木构件痕迹的脱水保护、底托的加固制作、木构件粘贴复原等,使文物得以长期保存。     

"虚拟"先人与十九世纪新加坡华人社会--兼论海外华人的"亲属"概念

在东南亚殖民地时代,"虚拟血缘"的组织原则对于华人移民社会的重组重建及其运作,具有重要的意义.本文以19世纪的新加坡为个案,考察华人移民如何透过埋葬先人的坟山组织建构"社群共祖"以整合华人社会,讨论东南亚华人虚拟的"先人"或"祖先"概念,进而思考海外华人的亲属研究问题.本文也讨论与比较了"虚拟血缘"组织原则在明代华南宗族"联宗"形态、台湾汉人社会发展早期的"合约式"宗族和东南亚华人坟山组织的不同运用.
