Analysing diet of small herbivores: the efficiency of DNA barcoding coupled with high-throughput pyrosequencing for deciphering the composition of complex plant mixtures [0.03%]
用于解析复杂植物混合物组成的有效性分析小型食草动物的饮食：DNA条形码与高通量测序相结合的方法
Eeva M Soininen,Alice Valentini,Eric Coissac et al.
Eeva M Soininen et al.
Background: In order to understand the role of herbivores in trophic webs, it is essential to know what they feed on. Diet analysis is, however, a challenge in many small herbivores with a secretive life style. In this pa...
Demographic analysis reveals gradual senescence in the flatworm Macrostomum lignano [0.03%]
人群分析揭示了扁虫Macrostomum lignano的逐渐衰老过程
Stijn Mouton,Maxime Willems,Patricia Back et al.
Stijn Mouton et al.
Free-living flatworms ("Turbellaria") are appropriate model organisms to gain better insight into the role of stem cells in ageing and rejuvenation. Ageing research in flatworms is, however, still scarce. This is partly due to culture diffi...
Faces capture the visuospatial attention of chimpanzees (Pan troglodytes): evidence from a cueing experiment [0.03%]
面孔吸引黑猩猩的空间注意：来自线索实验的证据

Background: Faces, as socially relevant stimuli, readily capture human visuospatial attention. Although faces also play important roles in the social lives of chimpanzees, the closest living species to humans, the way in ...
Habitat adaptation rather than genetic distance correlates with female preference in fire salamanders (Salamandra salamandra) [0.03%]
栖息地适应与遗传距离无关，但可决定火_salandra_salamandra_的雌性偏好
Barbara A Caspers,Claudia Junge,Markus Weitere et al.
Barbara A Caspers et al.
Background: Although some mechanisms of habitat adaptation of conspecific populations have been recently elucidated, the evolution of female preference has rarely been addressed as a force driving habitat adaptation in na...
Phylogenetic support values are not necessarily informative: the case of the Serialia hypothesis (a mollusk phylogeny) [0.03%]
系统发育支持值并没有像想象的那样可靠——以软件动物演化为例说明该问题
J Wolfgang Wägele,Harald Letsch,Annette Klussmann-Kolb et al.
J Wolfgang Wägele et al.
Background: Molecular phylogenies are being published increasingly and many biologists rely on the most recent topologies. However, different phylogenetic trees often contain conflicting results and contradict significant...
The central nervous system of sea cucumbers (Echinodermata: Holothuroidea) shows positive immunostaining for a chordate glial secretion [0.03%]
海参(棘皮动物：海 cucumber 总科)的中枢神经系统显示出脊索动物神经胶质分泌物的阳性免疫染色反应
Vladimir S Mashanov,Olga R Zueva,Thomas Heinzeller et al.
Vladimir S Mashanov et al.
Background: Echinoderms and chordates belong to the same monophyletic taxon, the Deuterostomia. In spite of significant differences in body plan organization, the two phyla may share more common traits than was thought pr...
Comparative morphology of the axial complex and interdependence of internal organ systems in sea urchins (Echinodermata: Echinoidea) [0.03%]
海胆(棘皮动物门：海胆纲)轴柱的比较形态学及其内脏系统间的相互依存关系
Alexander Ziegler,Cornelius Faber,Thomas Bartolomaeus
Alexander Ziegler
Background: The axial complex of echinoderms (Echinodermata) is composed of various primary and secondary body cavities that interact with each other. In sea urchins (Echinoidea), structural differences of the axial compl...
Biogeographical and evolutionary importance of the European high mountain systems [0.03%]
欧洲高山系的生物地理和进化的重要性
Thomas Schmitt
Thomas Schmitt
Europe is characterised by several high mountain systems dominating major parts of its area, and these structures have strongly influenced the evolution of taxa. For species now restricted to these high mountain systems, characteristic biog...
The hatching larva of the priapulid worm Halicryptus spinulosus [0.03%]
棘毛深刺螠Priapulusspinulosus的孵化幼虫阶段研究报告

Ralf Janssen
Despite their increasing evolutionary importance, basic knowledge about the priapulid worms remains limited. In particular, priapulid development has only been partially documented. Following previous description of hatching and the earlies...
Bacterial feeding induces changes in immune-related gene expression and has trans-generational impacts in the cabbage looper (Trichoplusia ni) [0.03%]
球孢白粉菌的喂食可引起免疫相关基因表达量的变化并产生跨世代的影响——以烟芽夜蛾为模型研究
