selection thresholdsimulationMost deleterious mutations have very slight effects on total fitness, and it has become clear that below a certain fitness effect threshold, such low-impact mutations fail to respond to natural selection. The existence of such a selection threshold suggests that many low-...
Natural Selection:Natural selection is the process whereby traits that are beneficial for the survival for the animal are selected for. These traits are passed down to the offsprings. Traits that are not beneficial will not pass down as effectively. For example a brown spider can outlive a ...
alleles will inevitably differ between flies and humans for many reasons, not least because flies do not experience the menopause or receive any indirect benefits from providing parental care. However, it is important to note that the aim of this experiment was simply to see if biasing selection...
As part of stress tests, the FRB previously conducted a qualitative assessment of selected firms’ capital planning practices, which covered “governance, risk management, internal controls, capital policies, incorporating stressful conditions and events, and estimating impact on capital positions,” howeve...
A great challenge for ecology in the coming decades is to understand the role humans play in eco-evolutionary dynamics. If, as emerging evidence shows, rap... M Alberti - 《Trends in Ecology & Evolution》 被引量: 123发表: 2014年 Genomic signature of natural and anthropogenic stress in wild...
Populations adapted to human-altered habitats in the native range are likely to increase in abundance within areas frequented by humans and associated with human transport mechanisms, thus enhancing the likelihood of transport to a novel range. Given that habitats are altered by humans in similar ...
humans principally introduce modern invaders, repeatedly and in large quantities, and in ways that can facilitate release from enemies and competitors. Associated increases in exotic species’ propagule rain, survival and competitive ability could enable some introduced species to overcome the tradeoffs th...
Humans are exposed to poly- and perfluoroalkyl substances (PFASs) from diverse sources and this has been associated with negative health impacts. Advances in analytical methods have enabled routine detection of more than 15 PFASs in human sera, allowing better profiling of PFAS exposures. The compo...
Selection of appropriate concentration of ES in the model system of the analysis, reflective of the concentration reported in humans in active area of exposure, is important to draw parallels between the effects in the model system and human beings. HPLC analysis of the serum from ES-treated mic...
