为了解白头叶猴(Trachypithecus leucocephalus)的栖息地利用规律及其影响因素,2016年2月至2017年1月,采用瞬时扫描取样法对广西崇左白头叶猴国家级自然保护区一群白头叶猴的栖息地利用进行了研究。结果表明,白头叶猴对山体不同部位的利用存在显著性差异(χ2 =39.467,df=3,P<0.001),其中,对崖壁(56.75±9.55)%的利用比例最大,其次是对山坡(39.42±10.93)%和山顶(2.98±2.54)%的利用,而对山脚(0.84±1.47)%的利用频率最低。白头叶猴对不同微生境类型的利用存在差异(χ2=27.709,df=3,P<0.001),其中对乔木(49.37±12.31)%的利用比例最大,其次是裸岩(24.05±13.61)%,随后依次为藤本(15.48±8.01)%和灌木(10.87±5.45)%。白头叶猴主要在山坡上觅食,利用崖壁移动、休息,进行社会活动;主要利用裸岩进行社会活动,觅食、移动、休息主要发生在乔木上。从整体来看,白头叶猴在雨季对乔木的利用频率显著大于旱季(Z=-2.680,n=12,P=0.007);雨季在山坡觅食频率显著大于旱季(Z=-2.517,n=12,P=0.012),而在崖壁觅食频率刚好相反(Z=-2.842,n=12,P=0.004);白头叶猴雨季在乔木休息的频率显著大于旱季(Z=-2.355,n=12,P=0.019)。白头叶猴对栖息地的利用受到温度的影响。白头叶猴对乔木的总体利用频率随着平均温度的升高而增加(r=0.664,n=12,P=0.018);觅食时,对崖壁、裸岩的利用频率均与平均温度成负相关关系(崖壁:r=-0.685,n=12,P=0.014;裸岩:r=-0.600,n=12,P=0.039);休息时,对乔木的利用频率与平均温度呈正相关关系(r=0.650,n=12,P=0.022)。不同季节,白头叶猴对栖息地的利用方式不同。白头叶猴的栖息地利用模式可能是在觅食利益和捕食风险之间作出的权衡,并受到环境温度的影响。 相似文献

白头叶猴栖息环境与栖息地选择的研究 总被引:3,自引:2,他引:3
通过样方法和焦点动物法分别对白头叶猴栖息环境进行了观察,并对栖息环境的植物多样性进行了统计分析。结果表明,白头叶猴栖息地可分为山脚、山腰、山顶和山弄平地4部分,各部分优势种植物不同,白头叶猴栖息地的Shannon Venner多样性指数为6.152,均匀度为0.8439,白头叶猴对石山山脚、山腰、山顶和山弄平地的利用率分布为66.45 5.65%,21.15±5.49%,12.78±6.8%。在山脚主要是休息和觅食,在山腰主要是移动,在山顶主要是冬季晒太阳。因此,保护白头叶猴的栖息地对保护白头叶猴有特别重要的意义。 相似文献

圈养白头叶猴春季昼夜活动节律 总被引:1,自引:0,他引:1
2008 年3 ~5 月,采用瞬时扫描法,对上海动物园5 只白头叶猴的行为进行24 h 昼夜连续观察。结果表明:春季圈养白头叶猴一天的活动起于06∶ 00 左右,结束于18∶ 00 或18∶ 30。白天白头叶猴的主要行为为休息、取食和移动,平均频次依次是13.79 次、4.75 次和2.18 次。夜间的主要行为为休息、移动和抓挠,平均频次依次是22.13 次、0.43 次和0.26 次。不同个体昼夜活动节律差异很大。其中,移动、理毛、玩耍和其它行为的差异显著。夜间无理毛和玩耍行为,移动行为在夜间21∶ 00, 00 ∶ 30, 03∶00 和04∶ 30 出现高峰。在22∶ 30, 01∶ 00, 02∶ 00, 03∶ 30, 04∶ 30 和05∶30 则出现抓挠高峰。这预示白头叶猴夜间休息时处于一个“轻睡眠”状态。同时,雌雄白头叶猴昼夜移动行为差异显著。 相似文献

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26a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。 相似文献

Understanding how animals cope with habitat‐specific environmental factors can assist in species conservation management. We studied the habitat use of four groups (two large and two small groups) of white‐headed langurs (Trachypithecus leucocephalus) living in the forest of southwest Guangxi, China between September 2016 and February 2017 via instantaneous scan sampling. Our results showed that the langurs primarily used hillsides (55.91% ± 6.47%), followed by cliffs (29.70% ± 5.48%), hilltops (7.26% ± 3.55%), flat zones (6.99% ± 6.58%), and farmlands (0.14% ± 0.28%). The langurs moved most frequently on hillsides (49.35% ± 6.97%) and cliffs (35.60% ± 9.17%). The hillsides were more frequently used (66.94% ± 7.86%) during feeding, and the langurs increased the use of hilltops during the rainy season, and the use of cliffs in the dry season. The langurs frequently rested on hillsides (49.75% ± 8.16%) and cliffs (38.93% ± 8.02%). The larger langur group used cliffs more frequently when moving and resting, whereas the small langur group used hillsides more frequently while resting. Langurs in all groups avoided the flat zones for feeding. Their use of habitat reflected the balancing of foraging needs, thermoregulation, and predator avoidance. We conclude that the ecological factors are determinants of habitat use for white‐headed langurs. Our findings suggest that conservation efforts should focus on protecting the vegetation on the hillsides and restoring the vegetation on the flat zones. 相似文献

A survey was performed to investigate the infection status of fishborne trematode (FBT) metacercariae in freshwater fish from Guangxi Zhuang Autonomous Region, China. A total of 307 freshwater fish of 31 species were collected from 5 administrative regions of Guangxi Zhuang Autonomous Region. They were examined by artificial digestion method from July 2003 to August 2004. No metacercariae were detected in fish from Fusui-xian. In fish from Mashan-xian and a market in Nanning, 3 species of metacercariae, Haplorchis taichui, Haplorchis pumilio, and Centrocestus formosanus, were mainly detected. Metacercariae (8 in number) of Clonorchis sinensis were found in 1 Chanodichthys dabryi purchased from a market in Nanning. In fish from Yangshuo, Metagonimus yokogawai metacercariae were detected from all 18 fish species examined. Total 13 C. sinensis metacercariae were found in 3 out of 10 Hemibarbus maculatus from Yangshuo. All 7 Zacco platypus from Yangshuo were infected with 8-112 Echinochasmus perfoliatus metacercariae. In fish from Binyang-xian, H. pumilo metacercariae were mainly detected in all 5 fish species examined, and only 1 metacercaria of C. sinensis was found in a Hemiculter leucisculus. From the above results, it was confirmed that some species of freshwater fish play a role of second intermediate hosts for FBT in Guangxi Zhuang Autonomous Region, China. In particular, 4 species of intestinal flukes, M. yokogawai, H. taichui, H. pumilio, and C. formosanus, were prevalent in fish hosts, whereas C. sinensis metacercariae were detected only in 3 fish species. 相似文献

Presbytis potenziani is found only on the Mentawai Islands, Indonesia, and its ecology and feeding and ranging behavior have
been little studied. I studied 10 groups ofPresbytis potenziani in the primary forests of North Pagai Island, Mentawai, Indonesia.P. potenziani used primarily the upper strata of the forests for feeding, movement, and resting. Groups remained cohesive during their
daily activities, ranged between 100 to > 1000 m daily, and occupied home ranges of ≤ 40 ha. Neither sex predominantly initiated
group movement. Locomotion was primarily quadrupedal, with frequent leaping. P. potenziani showed two feeding peaks, one in
early morning and one during midafternoon. P. potenziani fed mainly on climbers and trees of the Dipterocarpaceae. They ate
primarily leaves, but also fed on fruits and other plant parts. 相似文献

Populations of many Afro-Palearctic birds have declined, with those wintering in sub-Saharan Africa, such as Wood Warbler Phylloscopus sibilatrix, particularly affected. In this study we investigated the relationship between habitat characteristics and Wood Warbler presence/absence in the Centre Region of Cameroon. A total of six transects were established in three habitat types (forest, forest–savanna transitional zone and savanna). Call playback surveys were conducted monthly from November 2015 to April 2016 to determine Wood Warbler presence/absence. Detailed habitat measurements were also recorded in each transect. A total of 86 responses were recorded: 33 (mean 6.6 ± 2.3) in forest habitat, 47 (mean 9.4 ± 3.36) in the forest–savanna transitional zone, and 6 (mean 2 ± 1.1) in savanna habitat. Wood Warbler presence increased significantly with the number of trees between 3 and 7 m in height, and decreased significantly with the number of shrubs between 0.5 and 3 m in height. Anthropogenic disturbance such as the agricultural cycle and burning were not found to have an effect on Wood Warblers presence/absence. We conclude that Wood Warblers overwinter in all three habitat types with probability of detection greatest in the forest–savanna transitional habitat with a relatively low canopy and an open understorey. Forest clearance in sub-Saharan Africa potentially threatens wintering habitat for Wood Warblers. 相似文献

本文在文献研究和实地调查的基础之上, 结合目前开展的关于壮族生物多样性相关传统知识的调查、整理与编目工作, 分别从酸食文化、织染文化、地名文化和文学艺术的角度对壮族文化多样性和生物多样性之间的关系进行了初步探究, 并从自然崇拜、乡规民约和习惯法、传统生态观念以及传统医药文化等几个方面探讨了传统文化对当地生物多样性的保护作用。结果表明: (1)壮族文化多样性与生物多样性密切相关。丰富的生物多样性孕育了传统文化, 而传统文化的形成和发展又直接或间接地丰富了当地的生物多样性; (2)壮族人民在长期生产生活中创造的传统文化和传统知识促进了当地生物多样性的保护与可持续利用; 而对生物多样性的保护又进一步保障了当地传统文化的传承。本文还对传统知识和传统文化的发展现状及受威胁因素进行了讨论, 并以此为基础, 提出传承壮族传统文化、保护和可持续利用传统知识的相关建议, 即应通过加强宣传和立法, 建立传统知识数据库和发展乡村旅游等形式, 加强对传统知识与传统文化的保护。 相似文献
