岛野公司的成功秘诀

提起自行车变速器人们很自然地会把它与日本岛野公司(中文译名禧玛诺)联系起来,因为在当今世界岛野公司几乎成了自行车变速器的代名词,创建于1921年的岛野公司至今已有74年生产自行车传动变速件的历史。目前他已成为一家拥有近18亿美元资产总额的跨国公司。在德国、英国、荷兰、意大利、加拿大。

Influence of Climate and Daylength on the Activity Budgets of Feral Goats (Capra hircus) on the Isle of Rum, Scotland

Daytime activity budgets of feral goats （ Capra hircus ） were studied in 1981, 1982 and 2000 on the Isle of Rum, northwest Scotland. This paper analyzes the influence of key weather variables （temperature and rainfall） and seasonal variations in daylength on daytime activity budgets. This study showed that the percentage of daytime spent in feeding by feral goats on Rum Island decreased with average monthly temperature, while the percentage of daytime spent in lying increased and rainfall had no significant effects on the percentage daytime spent in feeding or lying. The daylength varied greatly from January to December with the longest daylength being in June and July, and the shortest one in December and January. The amount of daytime spent feeding decreased from summer to winter, although the percentage of daytime spent feeding increased greatly from summer to winter. The seasonal variations in daylength seem to be an important factor in constraining feral goats＇ activity, especially in the cold and wet winters when forage biomass and quality are both at their lowest level. We discuss the influence of such constraining effects on the forage intake of these goats and their winter survival rate, as well as its implication for population regulation of these goats.

深水光滩红树林恢复工程技术--以珠海野狸岛为例

设计了野狸岛红树林围堰种植试点工程项目的实施方案,并针对工程各阶段提出了围堰吹填工程技术、红树林人工营造技术和红树林管护措施等技术措施。首先,运用围堰吹填工程措施,垫高滩面至红树林生长所需高度(平均垫高0.8 m,表层20~30 cm为泥质土);然后,采用混交方式种植红树林苗木,前缘带状混交速生的无瓣海桑和拉关木,中后缘块状混交慢生的秋茄、桐花树和木榄,速生与慢生树种的种植比例2∶8;最后,对种植区域进行2~3 a封滩管护并补植苗木,以保证造林保存率不低于80%。野狸岛西侧滩涂红树林种植试点工程为今后华南地区红树林生态建设工程的设计及实施提供了参考。
