In some arthropods there is a discrepancy in the number of dorsal tergites compared to the number of ventral sternites and leg pairs. The posterior tergites of the Diplopoda (millipedes) each cover two sternites and two pairs of legs. This ...
Single locus complementary sex determination in Hymenoptera: an "unintelligent" design? [0.03%]
蜂目昆虫的单基因性别互补决定系统的“非智能”设计？

The haplodiploid sex determining mechanism in Hymenoptera (males are haploid, females are diploid) has played an important role in the evolution of this insect order. In Hymenoptera sex is usually determined by a single locus, heterozygotes...
The importance of immune gene variability (MHC) in evolutionary ecology and conservation [0.03%]
适应性免疫遗传多态性的生态与进化意义及保护生物学应用

Genetic studies have typically inferred the effects of human impact by documenting patterns of genetic differentiation and levels of genetic diversity among potentially isolated populations using selective neutral markers such as mitochondr...
Conservation and co-option in developmental programmes: the importance of homology relationships [0.03%]
发育程序中的保护与征用：同源关系的重要性
Matthias Sanetra,Gerrit Begemann,May-Britt Becker et al.
Matthias Sanetra et al.
One of the surprising insights gained from research in evolutionary developmental biology (evo-devo) is that increasing diversity in body plans and morphology in organisms across animal phyla are not reflected in similarly dramatic changes ...
The unsuitability of HTML-based colour charts for estimating animal colours--a comment on Berggren and Merilä (2004) [0.03%]
关于Berggren和Merilä(2004)对基于HTML的颜色图表估计动物颜色的不适用性的评论
Martin Stevens,Innes C Cuthill
Martin Stevens
Background: A variety of techniques are used to study the colours of animal signals, including the use of visual matching to colour charts. This paper aims to highlight why they are generally an unsatisfactory tool for th...
Role of early experience in ant enslavement: a comparative analysis of a host and a non-host species [0.03%]
早期经历在蚁奴现象中的作用——寄主和非寄主物种的比较分析
Rumsaïs Blatrix,Claire Sermage
Rumsaïs Blatrix
Background: Ants use the odour of the colony to discriminate nestmates. In some species, this odour is learned during the first days following emergence, and thus early experience has a strong influence on nestmate discri...
Shape based assignment tests suggest transgressive phenotypes in natural sculpin hybrids (Teleostei, Scorpaeniformes, Cottidae) [0.03%]
基于形状的分配检验表明自然鼠鱼杂交种具有过度表型（辐鳍鱼纲，刺鱼目，鼠鱼科）
Arne W Nolte,H David Sheets
Arne W Nolte
Background: Hybridization receives attention because of the potential role that it may play in generating evolutionary novelty. An explanation for the emergence of novel phenotypes is given by transgressive segregation, w...
The male genital system of the cellar spider Pholcus phalangioides (Fuesslin, 1775) (Pholcidae, Araneae): development of spermatozoa and seminal secretion [0.03%]
地穴小吊蛛（Pholcus phalangioides）的雄性生殖系统：精子和精液的发育

Peter Michalik
Background: Most arthropods pass through several molting stages (instars) before reaching sexual maturity. In spiders, very little is known about the male genital system, its development and seminal secretions. For exampl...

Identifying the individuals within a population can generate information on life history parameters, generate input data for conservation models, and highlight behavioural traits that may affect management decisions and error or bias within...

Maritime Antarctic freshwater habitats are amongst the fastest changing environments on Earth. Temperatures have risen around 1 degrees C and ice cover has dramatically decreased in 15 years. Few animal species inhabit these sites, but the ...
