Tropical parabiotic ants: Highly unusual cuticular substances and low interspecific discrimination [0.03%]
热带半生境蚂蚁:高度非同寻常的表皮物质和较低的种间辨别力
Florian Menzel,Nico Blüthgen,Thomas Schmitt
Florian Menzel
Background: Associations between animal species require that at least one of the species recognizes its partner. Parabioses are associations of two ant species which co-inhabit the same nest. Ants usually possess an elabo...

Ants and termites are the most abundant animals on earth. Their ecological success is attributed to their social life. They live in colonies consisting of few reproducing individuals, while the large majority of colony members (workers/sold...
Myogenesis in the basal bilaterian Symsagittifera roscoffensis (Acoela) [0.03%]
榍藻动物Roscoff海扁虫(Symsagittifera roscoffensis)(底栖两侧对称动物)的肌细胞生成
Henrike Semmler,Xavier Bailly,Andreas Wanninger
Henrike Semmler
Background: In order to increase the weak database concerning the organogenesis of Acoela - a clade regarded by many as the earliest extant offshoot of Bilateria and thus of particular interest for studies concerning the ...
Vocal mother-offspring communication in guinea pigs: females adjust maternal responsiveness to litter size [0.03%]
家兔母子间的发声交流:雌性根据幼崽数量调整抚育行为响应程度
Melanie Kober,Fritz Trillmich,Marc Naguib
Melanie Kober
Background: In parent-offspring communication, vocal signals are often used to attract attention and offspring might call to induce parental behaviour. In guinea pigs (Cavia aperea f. porcellus) mothers wean larger litter...
Blocking primers to enhance PCR amplification of rare sequences in mixed samples - a case study on prey DNA in Antarctic krill stomachs [0.03%]
Hege Vestheim,Simon N Jarman
Hege Vestheim
Background: Identification of DNA sequence diversity is a powerful means for assessing the species present in environmental samples. The most common molecular strategies for estimating taxonomic composition depend upon PC...

Lars-Henrik Heckmann et al.
Background: Eicosanoids are biologically active, oxygenated metabolites of three C20 polyunsaturated fatty acids. They act as signalling molecules within the autocrine or paracrine system in both vertebrates and invertebr...
Adult nutrition and butterfly fitness: effects of diet quality on reproductive output, egg composition, and egg hatching success [0.03%]
成人营养和蝴蝶体魄:饮食质量对繁殖产出、卵成分及卵孵化成功率的影响
Thorin L Geister,Matthias W Lorenz,Klaus H Hoffmann et al.
Thorin L Geister et al.
Background: In the Lepidoptera it was historically believed that adult butterflies rely primarily on larval-derived nutrients for reproduction and somatic maintenance. However, recent studies highlight the complex interac...
Development of the retinotectal system in the direct-developing frog Eleutherodactylus coqui in comparison with other anurans [0.03%]
与其它蛙类相比,树蟾(Eleutherodactylus coqui)视网膜-脑皮系统的发育特色
Gerhard Schlosser
Gerhard Schlosser
Background: Frogs primitively have a biphasic life history with an aquatic larva (tadpole) and a usually terrestrial adult. However, direct developing frogs of the genus Eleutherodactylus have lost a free living larval st...

Tobias Seidl
Background: During long-distance foraging in almost featureless habitats desert ants of the genus Cataglyphis employ path-integrating mechanisms (vector navigation). This navigational strategy requires an egocentric monit...
Plasticity of electric organ discharge waveform in the South African Bulldog fish, Marcusenius pongolensis: tradeoff between male attractiveness and predator avoidance? [0.03%]
南非塘鳢电器官放电波形的可塑性:雄性吸引力和捕食者回避之间的权衡?
Susanne Hanika,Bernd Kramer
Susanne Hanika
Background: In adult male Marcusenius pongolensis the duration of their Electric Organ Discharge (EOD) pulses increases with body size over lifetime (267 to 818 mus, field-measured). Spawning males have been observed to e...
