Evolutionary Relationships through Genome Comparisons02:54

Evolutionary Relationships through Genome Comparisons

6.9K
Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...

Genetics of Speciation02:16

Genetics of Speciation

20.9K
Speciation is the evolutionary process resulting in the formation of new, distinct species—groups of reproductively isolated populations.

Types of Genetic Transfer Between Organisms02:18

Types of Genetic Transfer Between Organisms

30.5K
Genetic transfer occurs when genetic information is passed from one organism to another. It occurs via two mechanisms: vertical gene transfer and horizontal gene transfer. Vertical gene transfer occurs when genetic information is transferred from one generation to the next, which happens much more frequently than horizontal gene transfer. Both sexual and asexual reproduction are forms of vertical gene transfer, where one or more organisms pass some or all of their genome onto their progeny.

Conservation of Small Populations02:04

Conservation of Small Populations

16.6K
Small population sizes put a species at extreme risk of extinction due to a lack of variation, and a consequent decrease in adaptability. This weakens the chances of survival under pressures such as climate change, competition from other species, or new diseases. Large populations are more likely to survive pressures such as these, as such populations are more likely to harbor individuals that have genetic variants that are adaptive under new stresses. Small populations are much less...

Gene Flow02:39

Gene Flow

37.5K
Gene flow is the transfer of genes among populations, resulting from either the dispersal of gametes or from the migration of individuals.

科学领域:

  • 生态学和进化论的发展
  • 科学出版科学出版
  • 数据科学数据科学数据科学

背景情况:

  • 数据和代码共享对于科学可信度和可重复性至关重要.
  • 期刊政策显著影响数据和代码共享实践.
  • 这些政策在生态和进化领域的范围和可访问性仍然不清楚.

研究的目的:

  • 评估275个生态和进化期刊的数据和代码共享政策的清晰度,严格性和时间.
  • 通过两个主要期刊的手稿提交来评估最初遵守这些政策.
  • 确定需要改进的期刊政策和其执行方面的领域,以提高可重复性.

主要方法:

  • 对275个生态和进化学期刊的政策分析.
  • 评估数据和代码共享政策的特点 (清晰度,严格性,时间).
  • 提交手稿的合规性评估 (n=2340对于皇家学会B的记录,n=571对于生态信件).

主要成果:

  • 只有22.5%的期刊鼓励和38.2%的期刊授权数据共享; 26.6%鼓励和26.9%的期刊授权代码共享.
  • 强制性共享政策更频繁地与同行评审要求相关 (59.0%的数据,77.0%的代码).
  • 鼓励共享与同行评审的联系较少 (40.3%的数据,24.7%的代码),这表明政策整合的空间更强.

结论:

  • 期刊政策在促进数据和代码共享方面发挥着关键作用.
  • 需要在政策明确性,严格性和合规性方面进行重大改进,以提高研究可重复性.
  • 提出了七项建议,以加强数据和代码共享实践以及科学出版的政策遵守.
