Ranging behavior of the François’langur(Trachypithecus francoisi)in limestone habitats of Nonggang,China被引量:2
2011年
Ranging behavior is an important aspect of animal behavior that researchers use to investigate ecological influences on individual behavior.We collected data on the ranging behavior of one group of François’langurs(Trachypithecus francoisi)between August 2003 and July 2004 in a limestone habitat within Nonggang Nature Reserve,China.We evaluated the influences of food availability,water resources and sleeping sites on ranging behavior.During the study period,the total home range size for the study group was 64.5 or(69.3 ha if the lacunae within the borders in which langurs were not observed were included),and the mean daily path length was 541 m.These are well within the range of variation reported in Trachypithecus species.The monthly range size was between 9.8 and 23.3 ha,and monthly range size correlated negatively with young leaf availability.The langurs tended to use a larger range size during young leaf-lean periods.The langurs did not use their home range uniformly,and 74%of their activities occurred within 35%of their home range.The most heavily used quadrats in the home range were located near the most frequently used sleeping sites,suggesting that sleeping sites have a significant influence on the ranging behavior of François’langurs in limestone habitats.

白头叶猴(Trachypithecus leucocephalus)栖息地景观格局的时空变化被引量:13
2008年
运用3S技术,以1973年MSS影像和1999年TM影像为主要数据源,研究了白头叶猴(Trachypithecus leucocephalus)栖息地26 a间景观格局的变化特征,并探讨了景观格局的变化及其对白头叶猴的影响。结果表明:1973年至1999年间白头叶猴栖息地景观格局变化剧烈,九重山、咘遵和弄官山3片区域内景观斑块平均面积平均减少了34.89%,聚集度平均下降了12.23%;同时景观多样性指数平均增加了14.15%,景观形状指数平均增加了31.08%,边界密度平均增加了36.39%,破碎度指数平均增加了64.17%;林地景观类型面积平均减少了18.50%,而农田、居民点等人为景观面积则大幅增加。栖息地景观格局的剧烈变化和环境质量的降低,改变了白头叶猴原始的生存环境,将会对白头叶猴的生存产生严重的影响。

亚洲象等野生动物对西双版纳尚勇自然保护区周边村寨的影响被引量:8
2007年
本文通过整理西双版纳州国家级自然保护区尚勇管理所多年的内部资料,了解亚洲象(Elaphas maximus)和其他野生动物在周边村寨附近活动的情况;并使用“双S”技术即GIS地理信息系统和GPS全球卫星定位系统进行分析,了解和掌握亚洲象活动分布及时间。由此对人与亚洲象等野生动物冲突的现状及其原因进行了讨论,并提出了管理对策。

广西扶绥黑叶猴食物水分含量的研究被引量:9
2010年
2006年1-12月,采用焦点动物取样技术研究了黑叶猴的觅食行为,并测定了黑叶猴食物的水分含量.结果表明,食物中的月平均水分含量在61.1%~76.4%之间,各个月份间食物的平均水分含量有显著性差异(χ2=22.00,df=11,p=0.024〈0.05).在不同的食物部位中,花、嫩叶、果实、成熟叶的月平均水分含量分别为74.32%、70.69%、62.46%、60.73%.不同生活型的食物平均水分含量不同,其中乔木的水分含量最高(71.43%),其次为藤本植物(68.55%),灌木(67.37%),最低为草本植物(63.03%).黑叶猴取食植物含水分较多的嫩叶部分作为主要的食物,但检验发现黑叶猴全年对食物种类的取食时间与该种类的平均水分含量没有显著的相关关系.因此,食物的水分含量不是影响黑叶猴选择食物种类的决定因素.

三种笼养灵长类活动时间分配的比较研究被引量:7
2008年
采用焦点动物法和连续记录法对3种笼养灵长类活动时间分配进行比较研究。结果表明,川金丝猴Rhi-nopithecus roxellanae和熊猴Macaca assamensis用于休息的时间多于猕猴Macaca mulatta,移动时间则相反;川金丝猴和猕猴用于理毛的时间多于熊猴。不同性别年龄组之间的活动时间分配有差异,主要表现在川金丝猴母亲用于理毛的时间明显多于成年儿子,用于玩耍的时间则相反;猕猴成年雄性的移动时间和理毛时间多于成年雌性,玩耍时间则少于成年雌性;熊猴成年雌性的移动时间多于成年雄性,与成年个体相比,幼体花更多的时间用于玩耍,而相应的减少了其休息时间。

Habitat use and locomotion of the François’langur(Trachypithecus francoisi)in limestone habitats of Nonggang,China被引量:5
2013年
We collected data on habitat use and locomotion of the François’langur(Trachypithecus francoisi)between August 2003 and July 2004 at Nonggang Nature Reserve,China.A total of 739 h of behavioral data were collected during this study.We tested 2 predictions:(1)that the langurs may have special patterns of habitat use and locomotion adaptive to the limestone habitat,and(2)the langurs may exhibit different patterns of habitat use and locomotion among different zones of limestone hill.Our results indicated that François’langurs spent more time in the low-risk,relatively food-poor cliff-hilltop areas.When young leaves and fruit were scarce in the dry season,the langurs increased their time in the high-risk,food-rich valley basin.François’langurs were semi-terrestrial,and leaping and climbing were their main locomotor modes.These behavioral patterns are considered to be related to characteristics of topography and vegetation in limestone habitat,such as large areas of cliff and discontinuous canopy.Our results also supported Prediction 2.The langurs confined locomotion to the main canopy and frequently adopted leaping while traveling in the hillside and valley basin.While traveling in cliff-hilltop areas,they tended to stay in the lower stratus(≤5 m)or move on the ground,and walking and climbing were their dominant traveling modes.
