铅华洗尽:浮华面纱下的本色回归

作者： Haley a.lovett 一叶

“素颜风潮”席卷时尚娱乐界，各大娱乐时尚杂志纷纷以明星“素颜”出镜为卖点。继法国版《Elle》杂志2009年4月号的主题“铅华洗尽”之后，美国版《Harper’s Bazaar》2009年9月号亦策划了一期名为“实实在在的美丽”的主题。这场“素... 详细信息

“素颜风潮”席卷时尚娱乐界，各大娱乐时尚杂志纷纷以明星“素颜”出镜为卖点。继法国版《Elle》杂志2009年4月号的主题“铅华洗尽”之后，美国版《Harper’s Bazaar》2009年9月号亦策划了一期名为“实实在在的美丽”的主题。这场“素颜革命”引发的不仅仅是对“本色回归”的讨论，更是满足了众看客的偷窥欲——铅华褪尽，明星还美丽吗？会不会如狗仔队偷拍的那些“妆后”照片那样，让人既惊又喜？——惊于化妆技术之高超，喜于明星也并非美得无懈可击。其实，无论是天然雕饰下，出水芙蓉般的素颜，抑或是浓墨重彩下，堪与桃花相映红的俏颜，真正让时尚娱乐界为之倾倒的，是名叫“美丽”的东西。

We sampled twenty populations of the vulnera- ble endemic shrub or tree, Arbutus pavarii Pampan., at different elevations and aspects within the A1-Akhdar mountainous region of Libya. Our sampling sites were at elevations ranging from 285 to 738 m above sea level, and several different habitats： vallies （locally known as wadis）, north- and south-facing slopes, and mountaintops. All individuals within each quadrat were studied. Population size and structure, and plant functional traits were assessed. None of the populations had a stable distribution of size classes. Some consisted mostly of small plants, with little or no fruit production; others consisted only of mid-sized and large plants, with high fruit production, but no juvenile recruitment. There was a significant increase in percent cover with increasing elevation; reproductive output （the number of fruits per branch and total number of fruits per individual） also generally increased with elevation. In some of these populations the lack of recruitment, and in others the failure to produce fruit, together constituted serious demographic threats. In light of these results, recommen- dations are made for conservation of this vulnerable endemic species.

Within the semi-desert landscape of northern Libya, two sub-humid escarpments occur: Al-Akhdar in the east and Nafusa (Jabal Al-Gharbi) in the west. This study compares plant communities in the two regions, which are along an elevation gradient, in terms of species composition and diversity, frequency of different Raunkiaer life forms, and reproductive phenology. The two regions differed in species composition and life-form frequency between regions and between elevation zones within each region. Patterns were associated with the lower rainfall and lower moisture-holding capacity of soils at Nafusa, resulting in more xeric conditions. Only 13% of species were shared between the two regional landscapes. Species diversity, life-form frequency, and duration of the flowering-fruiting phenophase were all affected by elevation above sea level. The duration of flowering and fruiting in spring and fall was associated with environmental conditions, although there were different thresholds in the two regions. There was both a spring and fall episode of flowering at Nafusa, but only spring flowering at Al-Akhdar. It is anticipated that there will be a gradual shift of plant communities to higher elevations and loss of certain sensitive species in response to ongoing climate change.
