Trade-off between morphological convergence and opportunistic diet behavior in fish hybrid zone [0.03%]
鱼杂交区形态趋同与机会性摄食行为之间的权衡关系
Emmanuel Corse,Caroline Costedoat,Nicolas Pech et al.
Emmanuel Corse et al.
Background: The invasive Chondrostoma nasus nasus has colonized part of the distribution area of the protected endemic species Chondrostoma toxostoma toxostoma. This hybrid zone is a complex system where multiple effects ...
Oscillating magnetic field disrupts magnetic orientation in Zebra finches, Taeniopygia guttata [0.03%]
震荡磁场干扰斑胸草雀Taeniopygia guttata的磁导向
Nina Keary,Tim Ruploh,Joe Voss et al.
Nina Keary et al.
Background: Zebra finches can be trained to use the geomagnetic field as a directional cue for short distance orientation. The physical mechanisms underlying the primary processes of magnetoreception are, however, largely...
Bourgeois queens and high stakes games in the ant Aphaenogaster senilis [0.03%]
嗜老叶甲蚁的雌性社会等级及其在培育新世代过程中的作用
Adam L Cronin,Thibaud Monnin
Adam L Cronin
Background: Many animals face some form of conflict over reproductive opportunities. Queen selection in social insect colonies represents a high-stakes conflict where competition occurs among multiple queens for a few or ...
No effect of mate novelty on sexual motivation in the freshwater snail Biomphalaria glabrata [0.03%]
淡水螺Biomphalaria glabrata的交配新颖性对其性动机无影响
Ines K Häderer,Johanna Werminghausen,Nico K Michiels et al.
Ines K Häderer et al.
Background: When mating effort (e.g. via ejaculates) is high, males are expected to strategically allocate their resources depending on the expected fitness gains from a given mating opportunity. One mechanism to achieve ...
Two matched filters and the evolution of mating signals in four species of cricket [0.03%]
两种匹配滤波器及四种蟋蟀交配信号的进化
Konstantinos Kostarakos,Matthias R Hennig,Heiner Römer
Konstantinos Kostarakos
Background: Male field crickets produce pure-tone calling songs to attract females. Receivers are expected to have evolved a "matched filter" in the form of a tuned sensitivity for this frequency. In addition, the periphe...
Jacob Engelmann,Sabine Nöbel,Timo Röver et al.
Jacob Engelmann et al.
Background: Electric fish navigate and explore their dark and turbid environment with a specialised electric sense. This active electrolocation involves the generation and perception of an electric signal and fish have pr...
Tiny but complex - interactive 3D visualization of the interstitial acochlidian gastropod Pseudunela cornuta (Challis, 1970) [0.03%]
微小而复杂-交互式三维可视化介隙蜗牛类无壳目伪乌拉科尼亚角cow品物种挑战斯(1970)
Timea P Neusser,Martin Heß,Michael Schrödl
Timea P Neusser
Background: Mesopsammic acochlidians are small, and organ complexity may be strongly reduced (regressive evolution by progenesis), especially in microhedylacean species. The marine interstitial hedylopsacean Pseudunela co...
Sponge budding is a spatiotemporal morphological patterning process: Insights from synchrotron radiation-based x-ray microtomography into the asexual reproduction of Tethya wilhelma [0.03%]
海绵芽殖是一种时空形态模式化过程——基于同步辐射X射线显微层析成像的威尔海姆海綿无性繁殖的新视野
Jörg U Hammel,Julia Herzen,Felix Beckmann et al.
Jörg U Hammel et al.
Background: Primary agametic-asexual reproduction mechanisms such as budding and fission are present in all non-bilaterian and many bilaterian animal taxa and are likely to be metazoan ground pattern characters. Cnidarian...
Phasing of muscle gene expression with fasting-induced recovery growth in Atlantic salmon [0.03%]
大西洋鲑鱼肌源性基因表达与饥饿诱导的恢复生长同步化研究
Neil I Bower,Richard G Taylor,Ian A Johnston
Neil I Bower
Background: Many fish species experience long periods of fasting in nature often associated with seasonal reductions in water temperature and prey availability or spawning migrations. During periods of nutrient restrictio...
Audience effects in the Atlantic molly (Poecilia mexicana)-prudent male mate choice in response to perceived sperm competition risk? [0.03%]
关于墨西哥剑尾鱼的观众效应-对感知到的竞争风险的谨慎配偶选择？
Madlen Ziege,Kristin Mahlow,Carmen Hennige-Schulz et al.
Madlen Ziege et al.
Background: Multidirectional interactions in social networks can have a profound effect on mate choice behavior; e.g., Poecilia mexicana males show weaker expression of mating preferences when being observed by a rival. T...
