Background: When threespine stickleback colonized fresh water, they repeatedly evolved reduced armour plating via changes in Eda allele frequency. This evolution is typically attributed to differential predation pressure ...
Efficient CRISPR-Cas9 editing of major evolutionary loci in sticklebacks [0.03%]
高效地在三刺鱼中进行CRISPR-Cas9基因编辑以研究主要进化性状的功能效应

Background: Stickleback fish are widely used to study the genetic and ecological basis of phenotypic evolution. Although several major loci have now been identified that contribute to evolutionary differences between wild...
Sex-specific growth, shape, and their impacts on the life history of a long-lived vertebrate [0.03%]
性别特异的增长和形态及其对一种长寿脊椎动物生活史的影响

Luke A Hoekstra et al.
Background: Individual growth rates both comprise and determine life-history phenotypes. Despite decades of interest in understanding the relationship between individual growth and life history, chelonian longevity has li...
Fitness trade-offs and developmental constraints in the evolution of soma: an experimental study in a volvocine alga [0.03%]
有机体体型进化的适应性变迁及发育约束：以眼虫藻类为材料的实验研究
Matthew D Herron,Susma Ghimire,Conner R Vinikoor et al.
Matthew D Herron et al.
Background: The evolution of mortal somatic cells was a critical step in the evolution of complex body plans and the major radiations of multicellular life. In the volvocine green algae, somatic cells are hypothesized to ...
A fluorescence in situ hybridization (FISH) protocol for stickleback tissue [0.03%]

Background: Threespine stickleback are an important model for behaviour and evolutionary studies. A growing number of quantitative trait loci (QTL) and gene expression studies are identifying genes related to ecologically...
Virulence evolution in a host-parasite system in the absence of viral evolution [0.03%]

Question: How does virulence evolve in the Drosophila melanogaster/sigma virus (DMelSV) system? Organisms: Drosophila melanogaster (hos...
The prevalence and persistence of sigma virus, a biparentally transmitted parasite of Drosophila melanogaster [0.03%]
Drosophila melanogaster 分子病毒的流行性和持续性研究

Question: How do vertically transmitted parasites persist? Organisms: Drosophila melanogaster (host) and sigma virus (parasite). ...
Sexually dimorphic body size and development time plasticity in Aedes mosquitoes (Diptera: Culicidae) [0.03%]
蚊科疟疾蚊属蚊虫二型体型及发育时间的可塑性研究

Jillian D Wormington
Background: Sexual size dimorphism (SSD) in insects often accompanies a sexual difference in development time, sexual bimaturism (SBM). Goal: ...
Distributions of reproductive and somatic cell numbers in diverse Volvox (Chlorophyta) species [0.03%]
多样伏隔藻物种的生殖细胞和体细胞数量分布
Deborah E Shelton,Alexey G Desnitskiy,Richard E Michod
Deborah E Shelton
Background: Volvox (Chlorophyta) asexual colonies consist of two kinds of cells: a large number of small somatic cells and a few large reproductive cells. The numbers of reproductive and somatic cells correspond directly ...

Devin M Drown et al.
Background: A host obtains symbionts by horizontal transmission when infected from the environment or contagiously from other hosts in the same generation. In contrast, vertical transmission occurs when a host obtains its...
