The Oweniidae are marine annelids with many unusual features of organ system, development, morphology, and ultrastructure. Together with magelonids, oweniids have been placed within the Palaeoannelida, a sister group to all remaining anneli...
The importance of being integrative: a remarkable case of synonymy in the genus Viridiscus (Heterotardigrada: Echiniscidae) [0.03%]
整合的重要性：Viridiscus属（异爪猛水蚤目：棘盾猛水蚤科）中同义词的一个显著案例

Adaptation to a hypertonic marine environment is one of the major topics in animal physiology research. Marine teleosts lose water osmotically from the gills and compensate for this loss by drinking surrounding seawater and absorbing water ...
Integrative taxonomy resolves species identities within the Macrobiotus pallarii complex (Eutardigrada: Macrobiotidae) [0.03%]
整合分类学解决了Macrobiotus pallarii复合体（细 tardigrade：Macrobiotidae）内的物种身份问题
Daniel Stec,Matteo Vecchi,Magdalena Dudziak et al.
Daniel Stec et al.
The taxonomy of many groups of meiofauna is challenging due to their low number of diagnostic morphological characters and their small body size. Therefore, with the advent of molecular techniques that provide a new source of traits, many c...
The formation of a hatching line in the serosal cuticle confers multifaceted adaptive functions on the eggshell of a cicada [0.03%]
蝉卵鞘上的孵化线具有多方面的适应功能
