Jochen Bw Wolf,Diethard Tautz,Fritz Trillmich
Jochen Bw Wolf
Background: Accurate formal taxonomic designations are thought to be of critical importance for the conservation of endangered taxa. The Galápagos sea lion (GSL), being appreciated as a key element of the Galápagos mari...
Apparent survival of the salamander Salamandra salamandra is low because of high migratory activity [0.03%]
高迁移活动导致欧洲火蜥蜴外观存活率低
Benedikt R Schmidt,Michael Schaub,Sebastian Steinfartz
Benedikt R Schmidt
Background: Understanding the demographic processes underlying population dynamics is a central theme in ecology. Populations decline if losses from the population (i.e., mortality and emigration) exceed gains (i.e., recr...

Boran Altincicek
Background: The marine annelid Platynereis dumerilii (Polychaeta, Nereididae) has been recognized as a slow-evolving lophotrochozoan that attracts increasing attention as a valuable model for evolutionary and developmenta...
Mating behaviour in the sea slug Elysia timida (Opisthobranchia, Sacoglossa): hypodermic injection, sperm transfer and balanced reciprocity [0.03%]
海蛞蝓Elysia timida（头楯亚纲，叶肢介总目）的交配行为：皮下注射、精子转移与互惠平衡
Valerie Schmitt,Nils Anthes,Nico K Michiels
Valerie Schmitt
Background: In simultaneous hermaphrodites with copulation and internal fertilization it is often unclear whether reciprocal sperm exchange results from the unconditional willingness of both partners to donate and receive...
A novel and ancient group of type I keratins with members in bichir, sturgeon and gar [0.03%]
一种新颖而古老的I型角蛋白大家族及其在肺鱼、鲟鱼和多鳍鱼等动物中的发现
Michael Schaffeld,Mark Haberkamp,Sonja Schätzlein et al.
Michael Schaffeld et al.
Background: Vertebrate epithelial cells typically express a specific set of keratins. In teleosts, keratins are also present in a variety of mesenchymal cells, which usually express vimentin. Significantly, our previous s...
Clouded leopard phylogeny revisited: support for species recognition and population division between Borneo and Sumatra [0.03%]
雾豹类的谱系再研究：支持物种识别以及划分加里曼丹岛和苏门答腊岛的种群分布
Andreas Wilting,Valerie A Buckley-Beason,Heike Feldhaar et al.
Andreas Wilting et al.
Background: The clouded leopard (Neofelis nebulosa) is one of the least known cat species and depletion of their forested habitats puts it under heavy pressure. Recently reclassification of Bornean clouded leopards (N. ne...
A new look at the ventral nerve centre of Sagitta: implications for the phylogenetic position of Chaetognatha (arrow worms) and the evolution of the bilaterian nervous system [0.03%]
重新审视萨吉塔腹神经中心：关于有毛虫门（箭虫）的系统发育位置及其两侧对称动物神经系统演化的意义
Steffen Harzsch,Carsten H G Müller
Steffen Harzsch
Background: The Chaetognatha (arrow worms) are a group of marine carnivores whose phylogenetic relationships are still vigorously debated. Molecular studies have as yet failed to come up with a stable hypothesis on their ...
Analysis of a possible independent origin of triploid P. formosa outside of the Río Purificación river system [0.03%]
三倍体Psathyrella formosa可能独立起源于普里费德赛オン河系以外地区的分析研究
Susanne Schories,Kathrin P Lampert,Dunja K Lamatsch et al.
Susanne Schories et al.
Background: Unisexuality, or all female reproduction, is rare among vertebrates. Studying these exceptional organisms may give useful information with respect to the evolution and maintenance of sexual reproduction. Poeci...

Gunnar Grah
Background: Desert ants (Cataglyphis fortis) are central place foragers that navigate by means of path integration. This mechanism remains accurate even on three-dimensional itineraries. In this study, we tested three hyp...
