异色跗虎天牛的种内变异探讨及再描述(鞘翅目,天牛科,天牛亚科)

对2011年6月采自云南勐仑的73头异色跗虎天牛Perissus mutabilis Gahan,1894标本进行研究,发现该种73号标本在鞘翅斑纹、前足爪开式、前胸背板颜色及斑点、后足腿节长度存在不同程度的差异,研究认为上述特征不宜用作该种分类鉴定的特征。红胸跗虎天牛Perissus mutabilis vitabilis Pic,1923和黑胸跗虎天牛Perissus mutabilis obscuricolorPic,1937依据部分上述特征建立,且特征出现交叉,分布区域与指名亚种异色跗虎天牛P.mutabilis mutabilis Gahan,1894重叠,建议取消红胸跗虎天牛P.mutabilis vitabilis Pic,1923和黑胸跗虎天牛P.mutabilis obscuricolor Pic,19372个亚种。并对异色跗虎天牛P.mutabilis Gahan,1894进行重描述。

金绒花天牛与金丝花天牛的鉴定及分布(鞘翅目,天牛科,花天牛亚科,花天牛族)(英文)

金丝花天牛Leptura aurosericans Fairmaire,1895广泛分布在中国南方与东南亚地区,而金绒花天牛Leptura auratopilosa(Matsushita,1931)仅分布于台湾岛。最近10年,国内在金绒花天牛与金丝花天牛的鉴定及分布记录方面出现了一些不一致的报道。为了澄清这些问题,在核对模式标本及检视系列标本(包括许多正在自然交配的成对标本)的基础上,重新描述了这两个种的形态特征,给出了这两个种的鉴别特征并提供了彩色照片,认为金绒花天牛是台湾特有种,目前在大陆尚未发现。

HABITAT DURATION,LENGTH OF LARVAL PERIOD,AND THE EVOLUTION OF A COMPLEX LIFE CYCLE OF A SALAMANDER,AMBYSTOMA TEXANUM

In many organisms, genotypic selection may be a less effective means of adapting to unpredictable environments than is selection for phenotypic plasticity. To determine whether genotypic selection is important in the evolution of complex life cycles of amphibians that breed in seasonally ephemeral habitats, we examined whether mortality risk from habitat drying in natural populations of small-mouthed salamanders (Ambystoma texanum) corresponded to length of larval period when larvae from the same populations were grown in a common laboratory environment. Comparisons were made at two levels of organization within the species: 1) among geographic races that are under strongly divergent selection regimes associated with the use of pond and stream habitats and 2) among populations within races that use the same types of breeding habitats. Morphological evidence indicates that stream-breeding A. texanum evolved from pond-breeding populations that recently colonized streams. Larvae in streams incur heavy mortality from stream drying, so the upper bound on length of larval period is currently set by the seasonal duration of breeding sites. We hypothesized that selection would reduce length of larval period of pond-breeders that colonize streams if their larval periods are inherently longer than those of stream-breeders. The results of laboratory experiments support this hypothesis. When grown individually in a common environment, larvae from stream populations had significantly shorter larval periods than larvae from pond populations. Within races, however, length of larval period did not correlate significantly with seasonal duration of breeding sites. When males of both races were crossed to a single pond female, offspring of stream males had significantly shorter larval periods than offspring of pond males. Collectively, these data suggest that differences in complex life cycles among pond and stream-breeders are due to genotypic selection related to mortality from habitat drying. Stream larvae in the common-environment experiment were significantly smaller at metamorphosis than pond larvae. Yet, the evolution of metamorphic size cannot be explained readily by direct selection: there are no intuitively obvious advantages of being relatively small at metamorphosis in streams. A positive phenotypic correlation was observed between size at metamorphosis and length of larval period in most laboratory populations. A positive additive genetic correlation between these traits was demonstrated recently in another amphibian. Thus, we suspect that metamorphic size of stream-breeders evolved indirectly as a consequence of selection to shorten length of larval period.     

A CHECK-LIST OF THE BIRDS OF SABAH, BORNEO

A short account of the geography of Sabah, North Borneo, is followed by a survey of the main habitats and bird communities. The greater part of the paper is devoted to a check-list of the birds of Sabah, which incorporates information collected since the standard work on Borneo by Smythies (1960). 504 species belonging to 65 families have been recorded.     

陕西蓝田公王岭“蓝田伟猴”化石的再研究

蓝田公王岭动物群中,唯一的一种非人灵长类化石由胡长康、齐陶(1978)定名为Megamacaca lantianensis(蓝田伟猴)。但按其形态,我们觉得把它归于疣猴亚科比较适宜。特别是与该亚科中的金丝猴属(Rhinopithecus)更为相像,例如蓝田标本下颌支与下颌体垂直,冠状突略向后弯,齿尖起伏较大等都显示了金丝猴的一般性质。至此,本文将蓝田伟猴归于金丝猴属,保留原有种名:Rhinopithecus(Megamacaca)lantianensis(Hu and Qi)。时代为早更新世晚期。     

贵州凤冈志留纪晚LLANDOVERY世植物黔羽枝研究综述

简要论述贵州凤冈志留纪Llandovery世晚期Pinnatiramosus qianensis Geng(黔羽枝)的研究历史、地层时代、主要特征、早期陆生维管植物起源和演化意义、争议焦点及其今后的研究途径和展望。P.qianensis代表了一类目前仍鲜为人知、由水生藻类植物向陆生环境过渡的植物类群,具有陆生维管植物某些重要特征,在后续演化过程中,可能是一类不成功的灭绝类群。由于P.qianensis的特有外部形态和复杂的内部解剖特征,对其认识引发了很大的争议,焦点集中在是否属于真正的志留纪植物(产出地层是否为志留纪Llandovery世晚期,是否属于这个时期的早期维管植物或植物根系)。作者认为:我国西南地区是探索早期陆生维管植物起源和早期演化的关键地区,通过一系列野外和室内研究,进一步强化对P.qianensis及其共生植物群的研究,并采用多学科交叉的方法,系统揭示P.qianensis的生物学属性、分类系统及其生态环境,在早期植物演化上提出新观点和演化模式,推进早期陆生维管植物起源、演化的研究。
