福建省武夷山和梅花山远盲蚓属蚯蚓四新种及其与近缘物种的遗传关系

福建省武夷山和梅花山国家级自然保护区地处中亚热带季风常绿阔叶林气候区,该区域物种多样性丰富,然而土壤动物蚯蚓的物种多样性研究相对较少。通过形态分类学方法和DNA条形码技术,本文报道在福建省武夷山和梅花山采集的巨蚓科(Megascolecidae)远盲蚓属(Amymthas)蚯蚓新物种4种:表土远盲蚓(A.epigenus Sun&Qiu,sp.nov.)、梅花山远盲蚓(A.meihuamontis Sun&Qiu,sp.nov.)、苔蘚远盲蚓(A.muscosus Sun&Jiang,sp.nov.)和腐土远盲蚓(A.humatalis Sun&Jiang,sp.nov.)。这4个新物种在Sims等(1972)的物种群中属于A.sieboldi-group,其受精囊孔均位于6/7~8/9节间。所有新种附形态学描述、图片以及与相似物种的形态学比较和提交至GenBank的条形码登记号。此外还通过在GenBank上同源性搜索,筛选出了与新物种亲缘关系较近的蚯蚓物种,并对其进行了遗传距离计算和分子系统发育关系的梳理。以上结果将福建省武夷山和梅花山国家级自然保护区记录的蚯蚓物种数由4种增加至8种。

海南岛蚯蚓物种组成及其系统发育分析

海南岛独特的地理位置和复杂的古地理事件使其成为我国生物多样性的热点地区。已有的海南岛蚯蚓资料显示, 该岛的蚯蚓区系十分特殊, 且与大陆地区蚯蚓存在扩散与迁移。然而, 当海南岛与周围大陆断开形成独立岛屿后, 海南岛蚯蚓如何为适应海南岛的环境而逐渐形成现在岛内的分布与区系, 仍然是一个值得研究和探讨的问题。因此, 本研究在海南岛全面调查和采集蚯蚓标本, 整理海南岛地区的蚯蚓物种组成及其地理分布特征, 并联合5个线粒体基因COⅠ、COⅡ、ND1、12S rRNA和16S rRNA构建海南岛蚯蚓的分子系统发育树, 推测其分化时间和祖先分布区域, 探讨海南岛蚯蚓在岛内的分化与扩散过程。研究结果表明: (1)海南岛共有蚯蚓6科9属122种, 巨蚓科蚯蚓为优势科, 且全部为环毛类蚯蚓, 其中103种为海南岛特有种。蚯蚓物种数沿海拔呈先增加后减少的趋势, 在800‒1,000 m最大; (2)海南岛环毛类蚯蚓不同水平的遗传距离与我国巨蚓科蚯蚓的遗传距离区间基本一致。物种水平上, 美丽远盲蚓(Amynthas scitulus*)与纬向远盲蚓(A. zonarius)的基因遗传距离最小。在亚种水平, 保宁腔蚓指名亚种(Metaphire magna magna)和保宁腔蚓小型亚种(M. magna minuscula)的遗传距离均接近整体的物种水平。在种群水平, 等毛远盲蚓(A. homosetus)不同种群间遗传距离均接近整体的亚种水平; (3)海南岛环毛类蚯蚓可划分为7个类群, 其祖先于68.26 Ma开始分化, 可能起源于吊罗山。在新生代, 7个类群均得到较大发展。通过对海南岛蚯蚓组成及系统发育的梳理, 不仅为我国蚯蚓物种多样性研究提供基础资料, 也为岛屿蚯蚓物种系统发育关系分析提供科学参考。

中国巨蚓科蚯蚓的起源与演化

截至2017年中国已记录巨蚓科蚯蚓579种(亚种), 优势类群为远盲蚓属(Amynthas)与腔蚓属(Metaphire), 其丰富的物种多样性值得深入研究。近年来的研究指出联合形态分类与分子系统发育可较好地探讨中国巨蚓科蚯蚓的起源、分化与扩散。本文概述了中国巨蚓科蚯蚓物种的起源、分化时间以及扩散历程, 探讨了受精囊孔、盲肠形状等重要特征的演化, 分析了现行分类系统的缺陷。多项研究表明, 中国巨蚓科主要类群的祖先起源于中南半岛, 于白垩纪末期至新生代初期进入中国, 在新生代得以繁荣发展; 受精囊孔的对数或位置是多起源的, 盲肠形状演化中有祖征重现的现象, 故使用少数形态特征进行类群划分的现行分类系统有待改进。此外, 中国巨蚓科蚯蚓的具体演化机制及影响因素仍不明确。因此, 在未来研究中整合形态特征、分子数据与地理格局、地质历史及环境因子等信息, 定量分析类群演化与古地理、生物与非生物因素间的关系, 将有助于全面厘清中国巨蚓科蚯蚓演化的具体机制。

Species Diversity,Distribution, and Microhabitats of Anurans on Mt. Kalo-Kalo of the Mt. Kalatungan Range Natural Park,Bukidnon, Philippines

Anurans are considered good indicators of habitat quality due to their bi-phasic life mode,limited dispersal abilities,and sensitivity to environmental changes brought about by habitat fragmentation,pollution,climate change,and emerging infectious diseases.This study aimed to determine species diversity and local distribution of anurans in lower(1000–1400 masl)and upper(1400–1600 masl)montane forests on Mt.Kalo-Kalo of the Mt.Kalatungan Range Natural Park,Central Mindanao,Southern Philippines by employing standard sampling techniques for amphibians.We recorded a total of 251 individual anurans,representing 12 species during a brief recent study period.Mt.Kalo-Kalo’s upper montane forest has a higher diversity index(H’=1.276)than the lower montane forest(H’=0.851).Despite the very low diversity indices,the level of endemism of anurans was 100%where ten of the recorded species are Mindanao Faunal Region endemics and an additional two species are Philippine endemics.Ansonia muelleri exhibited the highest local abundance and individuals of this species which constituted 73%of individual anurans observed.Most of the species encountered prefer terrestrial and aquatic microhabitats,specifically on the rocks and bank substrates along the rivers and streams.Three species of anurans(Philautus acutirostris,P.poecilius,and Rhacophorus bimaculatus)were strictly found in arboreal microhabitats.Limnonectes magnus and A.muelleri have overlapping microhabitats.Results indicate that for such a short survey and modest sampling effort,the lower and upper montane forests of Mt.Kalo-Kalo support high endemism of anuran species suggesting that conservation efforts continue to be a priority in this unique protected area.     

Wide-ranging chimpanzees at Mt. Assirik,Senegal

A 4-year study of the ecology and ethology of wild chimpanzees (Pan troglodytes verus)was carried out in far western Africa. Contacts with chimpanzees and the locations of their nests were noted to determine which types of habitat were most used and to estimate the density of the population and the size of its home range. The results show that this community has one of the lowest densities and largest home ranges of all populations of chimpanzees studied so far. As such, it may provide a useful model for the reconstruction of hominid evolution in the Plio-Pleistocene.     

New species and range extensions from Mt Namuli,Mt Mabu and Mt Chiperone in northern Mozambique

The three sections of this paper report on i) new species, ii) new records for the Flora Zambesiaca region and for Mozambique and iii) expansion of distributions of species previously thought to be endemic to particular mountains. Specimens have been collected from three mountains in north-central Mozambique visited during a collecting programme from 2006 to 2008 investigating the conservation value of the biodiversity of currently unprotected areas. Three new species: Crotalaria namuliensis, Isoglossa namuliensis and Helixanthera schizocalyx are described. Five taxa not previously recorded from the Flora Zambesiaca region are here recorded as new records for the region and 31 taxa are listed from Mozambique for the first time, including five taxa previously thought to be Malawi mountain endemics. The number of range extensions recorded from these Mozambican mountains is evidence of the paucity of specimens collected from this part of Mozambique and shows the need for continued collection in order to clarify the distributions of this region’s rarest species.     

Medicinal plants of Mt. Pelion,Greece

This study focuses on plants used for medicinal purposes in the Mt. Pelion area of Greece; however other plant uses were noted when discovered. A total of 225 taxa representing 77 families are presented along with habitat data and ethnobotanical information when relevant. Some notes on related species are also included. In addition to ethnobotanical field research which included collection of voucher specimens, ancient literature pertaining to plant usage was also consulted. Local markets that sold wild plants or their products were investigated as well. Some plants not known to be ethnobotanically significant were also collected in order to learn more about species distribution on Mt. Pelion. It is possible that ancient plant usage information that was lost due to the destruction of classical literary works has survived in the oral tradition in the Mt. Pelion area and elsewhere in Greece. A number of little known psychoactive and narcotic plant uses (including ivy as an additive to wine) are reported in this publication.

Ranging behavior ofMacaca thibetana at Mt. Emei,China

Food handouts from visitors to Mt. Emei, in The People’s Republic of China, have considerably increased the diversity of food available to an indigenous population of Macaca thibetana.Some 43% of the feeding time was spent at the trail area frequented by tourists. Ranging behavior was of two kinds: wandering around within the group’s most densely used areas and making peripheral excursions between the areas. Three kinds of trail-area use were observed: three-group overlapping, two-group overlapping, and exclusive. M. thibetanatended to use sheltered sites for sleeping, to ensure safety and/or to keep dry in a rainy habitat. Exclusively and successively used sleeping sites were noted. The average size of the home range per group was 3 km ²; the average population density for the entire range was 13/km², and the biomass was 109 kg/km². The population may be growing, a possibility that is also supported by previous analyses using data on group composition.     

The subalpine vegetation of Mt. Vysokaya, central Sikhote-Alin

The subalpine vegetation structure of Mt. Vysokaya, the Central Sikhote-Alin, is described. This vegetation consists mainly of subalpine spruce-fir forest, a complex of subalpine meadows, shrubs, groves of Betula lanata (B. ermanii s.l.), krummholz of Pinus pumila and alpine tundras. Significant disturbances in the vegetation structure were noted, especially in the forest-tundra ecotone accompanying a sharp reduction of the belts of Betula lanata and Pinus pumila. The altitudinal level of the upper timberline reaches 1600 m a.s.l. which is 250 m less than the expected altitude calculated by Kira's warmth index. An undergrowth of scattered trees of Picea and Betula are growing up to the mountain top. Based on these data and a review of the literature, we concluded that a catastrophic lowering of the timberline and devastation of the subalpine vegetation belt occurred several centuries ago, probably as result of fires.
