水位变动影响下三峡库区汉丰湖鸟类群落及多样性

受三峡水库夏落冬涨的水位调控方式影响,位于三峡库区腹心的重庆开州区汉丰湖形成22.5m水位落差。为了解汉丰湖鸟类群落结构与动态水位变化之间的响应关系,2015年3月—2016年2月对汉丰湖鸟类群落结构及多样性进行了调查。共记录鸟类97种,隶属12目32科,其中湿地鸟类49种,主要包括雁鸭类(18种)、鸻鹬类(13种)、鹭类(7种)及秧鸡类(5种)。研究表明:受水位变化影响,鸟类群落结构及其多样性变化显著。夏季(8月)低水位期(水位高程152.50m),鸟种数最高,为34种,Shannon-Wiener指数最高;肉食性鸟与食虫鸟是主要取食功能群;与夏季低水位期生境类型多样、消落带植物正处于生长旺盛期、食物资源丰富有关,是雀形目鸟类、鹭类、秧鸡类等适宜的栖息地。冬季(12月)高水位期(水位高程174.50m),鸟种数为30种,Shannon-Wiener指数、均匀度指数均最低,植食性鸟类是主要的取食功能群,鸟类数量最高;与冬季高水位期水面开阔、生境类型单一有关,高水位期的大水面有利于鸭类集群越冬。冬季在退水期(水位高程170.01m),水位下降导致汉丰湖生境结构变化,越冬鸟类数量和物种丰度降低,空间分布格局也随之变化。鸟类是三峡水库生物多样性的重要组成部分,为保护和提升三峡水库生物多样性,恢复和营造鸟类栖息地,应针对繁殖鸟和越冬水鸟的功能需求进行生态设计。

Seasonal fluctuations in population size and habitat segregation of Kittlitz's Plover Charadrius pecuarius at Barberspan Bird Sanctuary,North West province,South Africa

Seasonal fluctuations in population size reflect breeding patterns and movements of birds, but distinguishing residents from itinerant birds is difficult with partially migratory species such as Kittlitz's Plover. We determined changes in the size of Kittlitz's Plover populations in two microhabitats (Goose Point and Sandy Beach) at Barberspan Bird Sanctuary, North West province, South Africa, where we ringed waders between February 2008 and May 2010. Using a Bayesian model, we estimated the population of this species at these two sites from capture–recapture data gathered in eight 3- to 12-day collection periods. The estimated adult population at Goose Point peaked at 161 in October 2009, but decreased to about 40 in March 2009 and March 2010. The immature population peaked at 119 in January–February 2010. This, along with observations of nests and chicks, suggests that residents bred at Goose Point from September to March. The estimated number of adults at Sandy Beach increased from 48 in March 2010 to 380 in April 2010. Adults captured there in April 2010 formed feeding flocks and were heavier than the resident birds at Goose Point. These results suggest that Barberspan Bird Sanctuary supports resident and itinerant populations that are partially segregated in different microhabitats.

Two mitogenomes in Gruiformes (<Emphasis Type="Italic">Amaurornis akool</Emphasis>/<Emphasis Type="Italic">A. phoenicurus</Emphasis>) and the phylogenetic placement of Rallidae

Rallidae, with 34 genera including 142 species, is the largest family in the Gruiformes, the phylogenetic placement of this family was still in debate. The complete mitochondrial genomes (mitogenomes), with many advantageous characters, have become popular markers in phylogenetic analyses. We sequenced the mitogenomes of brown crake (Amaurornis akool) and white-breasted waterhen (Amaurornis phoenicurus), analyzed the genomic characters of mitogenomes in Rallidae, and explored the phylogenetic relationships between Rallidae and other four families in Gruiformes based on mitogenome sequences of 32 species with Bayesian method. The mitogenome of A. akool/A. phoenicurus was 16,950/17,213 bp in length, and contained 37 genes typical to avian mitogenomes and one control region, respectively. The genomic characters of mitogenomes in Rallidae were similar. The phylogenetic results indicated that, among five families, Rallidae had closest relationship with Heliornithidae, which formed a sister taxa to Gruidae, while Rhynochetidae located in the basal lineage. Within Rallidae, Rallina was ancestral clade. Gallirallus & Rallus and Aramides were closely related, Gallicrex & Amaurornis and Fulica & Gallinula had close relationships, and these two taxa formed a sister clade to Porphyrio & Coturnicops. Our phylogenetic analyses provided solid evidence for the phylogenetic placement of Rallidae and the evolutionary relationships among different genus within this family. In addition, the mitogenome data presented here provide useful information for further molecular systematic investigations on Gruiformes as well as conservation biology research of these species.     

福建漳江口红树林鹭科鸟类巢址选择

2011年4～5月、2012年4～5月,采用样线调查和样方调查相结合的方法对福建漳江口红树林国家级自然保护区内鹭科鸟类巢址与影响其选择的因子进行研究.t-检验结果显示,红树基径、盖度、距地面平均高度、植株密度及秋茄比5个参数在巢区样方(n=23)与对照样方(n=37)之间存在显著差异(P＜0.05),桐花比、距道路距离、距村庄距离与距池塘距离4个参数存在极其显著差异(P＜0.01).主成分分析表明,植被结构和干扰条件是影响鹭科鸟类巢址选择的主要因子,植被结构不仅能够影响鹭科鸟类群落结构,还受到鹭科鸟类集群繁殖影响.     

Fruiting phenology of animal-dispersed plants in response to winter migration of frugivores in a warm temperate forest on Yakushima Island, Japan

The fruiting phenology of animal-dispersed plants was observed in a warm temperate, evergreen forest on Yakushima Island. The number of ripe fruits was counted for 22 trees, four lianas and one parasitic epiphyte species with sapfruit. These fruits were consumed by birds and Japanese macaques (Macaca fuscata yakui). Birds with small gapes (e.g. Japanese white-eye [Zosterops japonica]) consumed only small fruit less than 6 mm in diameter, while birds with large gapes (e.g. red-capped green pigeon [Sphenurus formosae]) and Japanese macaques consumed a wide range of fruits from 4 to 16 mm in diameter. The larger animals did not ignore the smaller fruits. Brown-eared bulbul (Hypsipetes amaurotis) and Japanese white-eye were the main consumers of sapfruit in terms of frequency in winter. Some of the observed consumers were year-round residents, but most of the consumers migrated to Yakushima Island from the main islands of Japan to overwinter (from November to March), and their abundance in winter was four times as high as during the rest of the year (from May to October). In 23 of the 27 plant species investigated, sapfruit production coincided with their immigration season, whereas tree species bear capsules and nuts during autumn from September to November. We suggest that sapfruit species set their ripe period to the season when frugivorous birds are most abundant.     

A stem lineage representative of buttonquails from the Lower Oligocene of Germany – fossil evidence for a charadriiform origin of the Turnicidae

A new species of the charadriiform taxon Turnipax Mayr, 2000 is described from the Lower Oligocene fossil site Frauenweiler in southern Germany. The postcranial skeleton assigned to Turnipax oechslerorum sp. nov. is very well preserved and allows the recognition of significant, previously unknown osteological details of Turnipax , especially concerning the wing and pectoral girdle bones. We provide evidence that Turnipax is a stem lineage representative of the Turnicidae (buttonquails) and synonymize Turnipacidae Mayr, 2000 with Turnicidae Gray, 1840. Turnipax is the earliest fossil representative of the Turnicidae, which otherwise have no Paleogene fossil record. Because recent molecular studies support a charadriiform origin of buttonquails, the mosaic distribution in the skeleton of Turnipax of derived features of the Turnicidae and non-turnicid charadriiform birds is of particular interest. Turnipax exhibits a more plesiomorphic morphology than extant Turnicidae, and we assume that its habitat and way of living differed from that of crown group Turnicidae, which may not have diversified before the spread of grasslands during the Oligocene and Miocene.
