Control of annual reproductive cycle in the subtropical house sparrow (Passer domesticus): evidence for conservation of photoperiodic control mechanisms in birds [0.03%]
亚热带家燕年度生殖周期的调控机制：鸟类中光周期控制机制保守性的证据

Amit K Trivedi
Background: In many birds, day length (= photoperiod) regulates reproductive cycle. The photoperiodic environment varies between different seasons and latitudes. As a consequence, species at different latitudes may have e...
Quantification of damage in DNA recovered from highly degraded samples--a case study on DNA in faeces [0.03%]
一种量化来自严重降解样本的DNA损伤的方法——以粪便中的DNA为例
Bruce E Deagle,J Paige Eveson,Simon N Jarman
Bruce E Deagle
Background: Poorly preserved biological tissues have become an important source of DNA for a wide range of zoological studies. Measuring the quality of DNA obtained from these samples is often desired; however, there are ...
The role of thermal niche selection in maintenance of a colour polymorphism in redback salamanders (Plethodon cinereus) [0.03%]
红色后背嗜酸林蛙(Plethodon cinereus)热亲合力选择在颜色多态性维持中的作用

Erin E Petruzzi
Background: In eastern North America two common colour morphs exist in most populations of redback salamanders (Plethodon cinereus). Previous studies have indicated that the different morphs may be adapted to different th...
Support for a rare pattern of temperature-dependent sex determination in archaic reptiles: evidence from two species of tuatara (Sphenodon) [0.03%]
支持古老的爬行类动物中罕见的温度依赖性性别决定模式的新证据：两种 tuatara（Sphenodon）物种中的证据
Nicola J Mitchell,Nicola J Nelson,Alison Cree et al.
Nicola J Mitchell et al.
Background: The sex of many reptiles is determined by the temperature an embryo experiences during its development. Three patterns of temperature-dependent sex determination (TSD) have been defined, but one pattern where ...
From descriptive to predictive distribution models: a working example with Iberian amphibians and reptiles [0.03%]
从描述性分布模型到预测性分布模型：伊比利亚两栖类和爬虫类动物的实例分析

J W Arntzen
Background: Aim of the study was to identify the conditions under which spatial-environmental models can be used for the improved understanding of species distributions, under the explicit criterion of model predictive pe...
Neuroactive substances specifically modulate rhythmic body contractions in the nerveless metazoon Tethya wilhelma (Demospongiae, Porifera) [0.03%]
神经活性物质特异性调节无神经元动物Tethya wilhelma(Demospongiae，Porifera)的节律性机体收缩
Kornelia Ellwanger,Michael Nickel
Kornelia Ellwanger
Background: Sponges (Porifera) are nerve- and muscleless metazoa, but display coordinated motor reactions. Therefore, they represent a valuable phylum to investigate coordination systems, which evolved in a hypothetical U...
Functional neuroanatomy of the rhinophore of Aplysia punctata [0.03%]
阿氏斑点裸甲藻(Aplysia punctata)鼻咽隆起的功能神经解剖学研究
Adrian Wertz,Wolfgang Rössler,Malu Obermayer et al.
Adrian Wertz et al.
Background: For marine snails, olfaction represents a crucial sensory modality for long-distance reception, as auditory and visual information is limited. The posterior tentacle of Aplysia, the rhinophore, is a chemosenso...
Genetic analysis of male reproductive success in relation to density in the zebrafish, Danio rerio [0.03%]
密度对斑马鱼雄性繁殖成功遗传分析的影响研究
Rowena Spence,William C Jordan,Carl Smith
Rowena Spence
Background: We used behavioural and genetic data to investigate the effects of density on male reproductive success in the zebrafish, Danio rerio. Based on previous measurements of aggression and courtship behaviour by te...
Cardiovascular system in larval zebrafish responds to developmental hypoxia in a family specific manner [0.03%]
发育性低氧对斑马鱼幼体心血管系统的影响具有品系特异性
Francisco B-G Moore,Michelle Hosey,Brian Bagatto
Francisco B-G Moore
Background: Genetic and environmental variation are both known to influence development. Evolution of a developmental response that is optimized to the environment (adaptive plasticity) requires the existence of genetic v...

Matina C Kalcounis-Rueppell
Background: There has been considerable research on rodent ultrasound in the laboratory and these sounds have been well quantified and characterized. Despite the value of research on ultrasound produced by mice in the lab...
