为了解城市社区生物多样性的季节变化特点,文章以城市鸟类为研究对象,于2018年4月—2019年3月,利用样线法对林科院社区进行实地鸟类调查,并通过鸟类丰富度、多样性、均匀度等指数探讨鸟类群落结构的季节变化规律。调查共记录到鸟类31种,其中,留鸟12种、旅鸟10种、夏候鸟4种、冬候鸟3种;全年优势种为麻雀(Passer montanus)和灰喜鹊(Cyanopica cyanus);鸟类区系以古北界为主,生态类群以鸣禽为主,取食方式以虫食性为主;鸟类群落结构季节变化显著(从种类看,秋季最多,春季次之,夏季最少,并于10月份达到了峰值;从数量看,冬季最多,秋季次之,夏季最少,并于8月份达到最低值,11月份达到最高值);鸟类群落结构变化的原因主要来自于候鸟的季节性迁徙和留鸟的季节性繁殖。 相似文献

In central Argentina, Serrano forest has a long history of fire disturbance; however, the impact of fire on avifauna remains unknown. We compared the avian–habitat relationships in forest patches with low, moderate, and high fire regimes using a community-level (species richness, abundance, ordination and guilds) and species-level (indicator species analysis) approach. In patches under each fire condition, we recorded bird community composition, richness and abundance, and different vegetation structure variables. The site under high-severity fire regime was structurally poor and had been converted from original forest to dense grassland. There, diversity of bird community was low, retaining approximately 30 % of the species present in the least impacted site. Avian assemblage was dominated by generalist and open area birds. Guilds were underrepresented, showing an important reduction of foliage granivorous, nectarivorous, omnivores, and foliage and bark insectivorous, and absence of fly-catchers. Moreover, low abundance of forest understory, midstory, and canopy species and of birds belonging to open and closed nesting guilds was detected. By contrast, under low and moderate-severity fire regimes highest bird diversity as well as highest representativeness of most guilds was observed. Forest bird species were strongly associated with low fire disturbance, whereas moderate fire disturbance was characterized by the presence of forest and generalist species. Given the critical conservation status of Serrano forest in Córdoba, Argentina, habitat restoration and protection of forest relicts could be suitable measures to promote avifauna preservation. 相似文献

四川海子山自然保护区鸟类群落结构及多样性 总被引:5,自引:0,他引:5
应用样线法,调查海子山自然保护区鸟类的组成和群落结构,经调查确认保护区内有鸟类16目48科210种,以留鸟和夏候鸟为主,鸟类区系成分复杂,古北界种类略占优势。根据鸟类栖息地的生境类型,将保护区鸟类划分为5个群落。调查得知,不同群落的优势种、常见种有较大差异;同一群落类型的物种组成、数量、遇见频次的季节差异明显。运用Shannon Weinner指数计算各群落的多样性;采用E=H/Hmax。计算群落中各群落物种的均匀度;用百分率相似性数(index of percent similarity)对各群落做相似性比较。结果表明:保护区内鸟类群落结构与各群落类型内部的空间异质性程度密切相关,群落的空间结构越复杂,则物种多样性就越高;湿地鸟类群落的均匀度指数最高,而高山灌丛鸟类群落的均匀度指数最低;各群落类型百分比相似性指数均较低;鸟类群落结构具有较大差异。 相似文献

This study examined the effects of framework trees, planted in 1998, and bird community on the natural recruitment of tree
seedling species in a forest restoration experiment designed to test the framework species method of forest restoration established
by Chiang Mai University’s Forest Restoration Research Unit (FORRU-CMU). Tree seedlings establishing beneath five framework
tree species: Erythrina subumbrans (Hassk.) Merr., Hovenia dulcis Thunb., Melia toosendan Sieb. & Zucc., Prunus cerasoides D.Don and Spondias axillaries Roxb., were surveyed. Five trees of each species were selected in the 8-year-old trial plots. Birds visiting each tree were
observed to determine possible seed dispersal activities. Thirty-six tree seedling species were found beneath the selected
trees, of which 11 were wind-dispersed and 25 were animal-dispersed. The population density of animal-dispersed tree seedlings
was higher than the wind-dispersed seedlings beneath all selected framework trees. The sample plots beneath P. cerasoides supported the highest population density of tree seedlings. Forty-nine bird species were recorded visiting the framework
trees between July 2006 and June 2007. Non-frugivorous birds were recorded more frequently than the frugivorous birds. The
effects of birds on seedling recruitment were different among each of the selected framework tree. Bigger trees, which attracted
high number of birds by providing food resources, roosting and nesting sites may increase the seed deposition more than smaller
trees with fewer attractants. 相似文献
