Immune response to sympatric and allopatric parasites in a snail-trematode interaction [0.03%]
同地和异地理螺体 Trematoda 间免疫反应的对比研究
Erik E Osnas,Curtis M Lively
Erik E Osnas
Background: The outcome of parasite exposure depends on the (1) genetic specificity of the interaction, (2) induction of host defenses, and (3) parasite counter defenses. We studied both the genetic specificity for infect...
Behavioral and neuroendocrine consequences of social subjugation across adolescence and adulthood [0.03%]
贯穿青少年期和成年期的社会从属地位的神经内分泌及行为后果
Craig F Ferris,Tara Messenger,Ross Sullivan
Craig F Ferris
BACKGROUND: Social subjugation is a very significant and natural stressor in the animal kingdom. Adult animals defeated and subjugated during establishment of dominance hierarchies or territorial encounters can be highly submissive in futur...

Comparative performance of the 16S rRNA gene in DNA barcoding of amphibians [0.03%]
DNA条形码技术在两栖动物分类中的应用及16S rRNA基因的比较性能研究
Miguel Vences,Meike Thomas,Arie van der Meijden et al.
Miguel Vences et al.
BACKGROUND: Identifying species of organisms by short sequences of DNA has been in the center of ongoing discussions under the terms DNA barcoding or DNA taxonomy. A C-terminal fragment of the mitochondrial gene for cytochrome oxidase subun...
Asymmetry in host and parasitoid diffuse coevolution: when the red queen has to keep a finger in more than one pie [0.03%]
宿主和寄生虫分散协同进化的不对称性：当红皇后不得不兼顾多个派系时
Laurent Lapchin,Thomas Guillemaud
Laurent Lapchin
BACKGROUND: Coevolution between pairs of antagonistic species is generally considered an endless "arms race" between attack and defense traits to counteract the adaptive responses of the other species. PRESENTATION OF THE HYPOTHESIS: When m...
Opisthobranchia (Mollusca, Gastropoda) - more than just slimy slugs. Shell reduction and its implications on defence and foraging [0.03%]
头足纲(软体动物门，腹足纲)-不仅仅是粘滑的海兔。壳的退化及其对防御和觅食的影响
Heike Wägele,Annette Klussmann-Kolb
Heike Wägele
BACKGROUND: In general shell-less slugs are considered to be slimy animals with a rather dull appearance and a pest to garden plants. But marine slugs usually are beautifully coloured animals belonging to the less-known Opisthobranchia. The...
Linking biogeography to physiology: Evolutionary and acclimatory adjustments of thermal limits [0.03%]
生物地理学与生理学的联系：热极限的进化和习得性调整

Temperature-adaptive physiological variation plays important roles in latitudinal biogeographic patterning and in setting vertical distributions along subtidal-to-intertidal gradients in coastal marine ecosystems. Comparisons of congeneric ...
Secondary neurons are arrested in an immature state by formation of epithelial vesicles during neurogenesis of the spider Cupiennius salei [0.03%]
蛛网膜囊的形成使杯口蜘蛛(Cupieninius salei)的神经元发育停滞在幼稚阶段
Angelika Stollewerk
Angelika Stollewerk
BACKGROUND: In the spider Cupiennius salei about 30 groups of neural precursors are generated per hemi-segment during early neurogenesis. Analysis of the ventral neuromeres after invagination of the primary neural precursor groups revealed ...
Homologs of wingless and decapentaplegic display a complex and dynamic expression profile during appendage development in the millipede Glomeris marginata (Myriapoda: Diplopoda) [0.03%]
千足虫Glomeris marginata的附肢发生过程中wingless和decapentaplegic同源基因表达模式复杂且动态变化
Nikola-Michael Prpic
Nikola-Michael Prpic
BACKGROUND: The Drosophila genes wingless (wg) and decapentaplegic (dpp) comprise the top level of a hierarchical gene cascade involved in proximal-distal (PD) patterning of the legs. It remains unclear, whether this cascade is common to th...
The structure of biodiversity - insights from molecular phylogeography [0.03%]
分子系统地理学揭示的生物多样性分布格局及形成机制
Godfrey M Hewitt
Godfrey M Hewitt
DNA techniques, analytical methods and palaeoclimatic studies are greatly advancing our knowledge of the global distribution of genetic diversity, and how it evolved. Such phylogeographic studies are reviewed from Arctic, Temperate and Trop...
