摘要： 如此冗长的假期，唆使自己放纵一下吧。唉，也是的，虽然现在假期不算少，但挪出整块的时间来却也颇难。比如，《圣诞节清唱剧》，《马太受难曲》，或者随便找一部歌剧来，也要两三个小时。幸好有这个长假，两个半小时的《圣诞节清唱剧》今天可以听足三遍。

摘要： 随着圣诞节的临近,以往每到这个时候,玩具商就在应付铺天盖地的圣诞订单,而今年订单却少得可怜。近来,部分玩具制造商反映,许多厂家的仓库有大量存货无法出口,只能转销国内市场。此外,各项成本增加以及银行提高贷款要求,使企业不仅利润减少而且造成现金流不畅;同时,企业用工成本还在上升,工人供应不足,出现了招工难现象;加上出口质量标准提高、

摘要： 圣诞节前一天,波士顿从早上就开始飘雪,过了午后,雪越下越大,纷纷扬扬,一层一层,将布鲁克兰镇的房屋、树木、湖泊都涂成了银白色.“好好玩吧,这是我们在美国过的最后一个圣诞了.”葛利望着窗外正在堆雪人的儿子女儿,心里说道.五分钟前,他刚刚按下电邮的发送键,回绝了Bruce意欲高价购买他酿茶技术的请求.

关键词： Species limits   cryptic species   dilatata   fecunda  

摘要： The presence of sibling species within the marine gastropod genus Crepipatella has complicated the taxonomy of members of the group. Since the establishment of the genus, 15 species have been described, but recent studies have indicated that there are only five valid species, two of which inhabit the coasts of Chile, namely C. dilatata and C. fecunda. The two species are morphologically indistinguishable as adults, but can be differentiated on the basis of their encapsulated developmental stages. The primary aim of this study was to reconstruct phylogeny within the genus, and to establish species limits of C. dilatata and C. fecunda, using mitochondrial DNA data. To this end, we used maximum parsimony, maximum likelihood, and Bayesian inference to reconstruct phylogenies using 589 bp of the cytochrome oxidase I (COI) gene. The mtDNA phylogenies were then used as input in a general mixed Yule-coalescent (GMYC) analysis to estimate species boundaries. In addition, quarter likelihood mapping was used to test a posteriori the confidence of inner branch patterns in the phylogenetic tree. Both DNA tree-based and GMYC methods provide support for five isolated lineages within this species complex. Our data also suggest that Late Pleistocene and Holocene fragmentation and subsequent range expansion events may have shaped contemporary genetic patterns of Crepipatella in South America.

摘要： 野生蓝莓是地球上真正的、稀有的蓝色食物之一,也是少数原产于北美的水果之一。它生长在加拿大大西洋四省、魁北克未被破坏、无污染的土地上,已经自然生长了一万年,两年仅收获一次且仍以传统的手工采摘为主要手段。野生蓝莓具有天然的超级抗氧化能力,口味甜美且香味浓郁独特,易于搭配在多种食品和饮品中,且能通过各种方式加工保留其口味、组织、形状、色泽和香味,是浆果中

关键词： Coral reefs   Trophic structure   Fishing   FORAM Index   Foraminifera   Nutrification   Kiritimati  

摘要： Community assemblages of live and dead benthic foraminifera from Kiritimati (Christmas) Island, Kiribati, were used to investigate changes in nutrification before and after human occupation. Benthic foraminiferal assemblages have previously been shown to have strong empirical relationships with water quality: mixotrophic, symbiont-bearing foraminifera dominate in clear, nutrient-poor waters, while heterotrophic and/or opportunistic foraminifera are more prevalent in polluted or nutrified waters. After human occupation, the proportion of mixotrophic taxa decreased significantly at all sites on Kiritimati with the largest decreases observed at sites with the highest fishing pressure. These changes in the benthic foraminiferal assemblage indicate that nutrification has occurred on Kiritimati over the scale of decades, possibly due to changes in trophic structure and nutrient cycling caused by fishing.
