Abstract
François' langur (Trachypithecus francoisi) is an indicator species living in Karst rocky habitats. To understand the François' langurs ecological adaptation to high-altitude habitat, we used the field tracking method to collect home-range data and daily travel distance of François' langur at high-altitude (800-1400 m) areas of Kuankuoshui National Nature Reserve between April 2008 and March 2009. The results revealed the following: (1) according to the grid cell method, the home range of François' langurs was estimated to be 50.7 ha. The area in the winter-spring season was larger than in the summer-autumn season (37.7 vs. 27.7 ha). According to the minimum convex polygon method by GIS, the home range of François' langurs in the winter-spring season and the summer-autumn season was 123.5 and 68.8 ha, respectively. The whole-year home range of François' was clearly larger than the grid cell method (140.4 vs. 50.7 ha). (2) The home range of François' langurs had clear superposition. Langur's core areas were concentrated in three small areas, which only occupied 18.2% of the home range. (3) The langur had a short daily travel distance (230-1115 m) and significant seasonal differences. The summer-autumn season moving distances being obviously shorter than the winter-spring season (517 vs. 785 m). (4) With the decrease in the availability of food resource in winter-spring season, the home range and daily travel distance of François' langurs significantly increased. (5) Living in the high altitudes, François' langurs tended to form a larger group (≥ 8 individuals), which is larger than other groups at lower altitude, had the larger home range, and had shorter daily travel distance. Our results indicate that colobines' survival strategies tend to form a larger home range and shorter day-traveling distance to adapt to high-altitude and low-temperature habitat.
弗朗索瓦叶猴(Trachypithecus francoisi)是喀斯特岩栖的指示物种。为了解羊角叶猴对高海拔生境的生态适应性,2008年4月至2009年3月,采用野外跟踪法采集了宽阔水国家级自然保护区海拔800 ~ 1400 m地区羊角叶猴的家程和日行程数据。结果表明:(1)根据网格单元法,估算出法国叶猴的栖息范围为50.7 ha。冬春季节的面积大于夏秋季节(37.7 ha vs. 27.7 ha)。根据GIS的最小凸多边形法,冬春季节和夏秋季节,叶猴的栖息地面积分别为123.5 ha和68.8 ha。franois法的全年房屋面积明显大于网格法(140.4 ha vs. 50.7 ha)。(2)法国叶猴的栖地有明显的重叠性。叶猴的核心区集中在3个小区域,仅占栖地的18.2%。(3)叶猴日游距离较短(230 ~ 1115 m),季节差异显著。(4)随着冬春季节食物资源可得性的降低,叶猴的活动范围和日活动距离显著增加。(5)生活在高海拔地区的褐叶猴倾向于形成更大的群体(≥8只),比低海拔地区的其他类群规模更大,活动范围更大,日活动距离更短。研究结果表明,为适应高海拔、低温生境,耧斗菜的生存策略倾向于形成更大的活动范围和更短的日游距离。
期刊介绍:
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
