Although this hinders drawing conclusions on longer selection scenarios, this approach does highlight potential contemporary selection pressures “acting here and now”, including newly arising selection pressures such as education and income. Especially among men, social status has always been a ...
Aneuploidy, an abnormal number of chromosomes within a cell, is a hallmark of cancer. Patterns of aneuploidy differ across cancers, yet are similar in cancers affecting closely related tissues. The selection pressures underlying aneuploidy patterns are not fully understood, hindering our understanding of...
In such high Arctic, less productive ecosystems there may be a greater dependence on a few prey-rich habitats, perhaps resulting in clearer selection pressures for specific prey species than in more productive, low Arctic areas. Besides being generally more productive, the habitat structure of our...
predicted to be at least partly convergent when such changes are analogous. Our results largely match this scenario because ancestral selection pressures on traits directly related to cooperative social colony life, such as chemosensory perception for communication, synaptic plasticity for behavioral ...
(Fig.3a), indicating that these local temperature features might collectively act as selective pressures shaping the SNP landscape. Then, we profiled the correlation coefficient |Rho| along the genome, and found that |Rho| values between AF and various bioclimatic variables showed similar profiles ...
The action of selection leaves signs along the genome as responses to environmental and anthropogenic pressures that can be revealed using specific methodologies and bioinformatic tools. We applied three complementary methods for detecting a wider range of candidate genes that can be further investigated....
S6). Different selective pressures from heterogeneous environments (surface and bottom water) acted on microbial communities, which produced great composition differences and enhanced the relative importance of variable selection. It has been reported that bacterial communities between May and September ...

The development of agriculture also changed the selective pressures on humans in another way: Increased population density made the transmission of infectious diseases easier, and it probably expanded the already substantial role ofpathogensas agents of natural selection. That role is reflected in the ...
