evolution, this indicates that infection resistance can impose random bottlenecks that determine the genetic composition of the infective population and not necessarily select for new strain lineages40. For example, rapid evolution is reported as an important mechanism of genetic variation in phytopathogen...
Furthermore, range shifts of Antarctic krill were out of step with the pace of warming, with an abrupt shift occurring during a warming hiatus45. This nonlinearity was attributed to population processes, including an abrupt occupation of a new spawning ground in the south. Species with low ...
The demographic history inferred from the analysis indicates that M. lacei has experienced significant population declines during past glaciations, with a stabilization of population size around 10,000 years ago. However, the current population size is alarmingly low, with only 52 individuals known in...
Genome content of key sulfur-cycling MAGs. Genes involved in oxidation reactions are in pink; reduction in green; disproportionation in blue. Yellow text indicates sulfur species putatively exchanged between S-oxidizing and S-reducing bacteria. Complete gene names and genome content are located in Tab...
We then consider the potential negative consequences of overinterpretation and review the growing body of evidence that indicates these consequences are already occurring. 2.1. Improved recognition It is possible that, as a result of the reduced stigma and improved mental health literacy resulting from ...
Decay experiments have demonstrated that recalcitrant cuticular remains of ecdysozoans can survive for extended periods of time as long as they remain undisturbed by scavengers, whereas more labile tissues will become degraded by the activity of naturally occurring endogenous bacteria (Caron and Jackson...
The term "human" in the definition indicates that language is possessed by human beings only and is very different from the communication systems of other living creatures. The term "communication" means that language makes it possible for its users to talk to each other and fulfill their ...
13. Why is Bill going to Germany? A. To work on a project B. To study German. C. To start a new company. 14. What did the woman dislike about Germany? A. The weather. B. The food. C. The schools. 15. What does Bill ...
Our analysis indicates both dry and wet bias, each of which has significant implications for either side of the drought assessment spectrum. The extensive dry bias will influence the perspective of decision makers on drought magnitude such that drought will appear more severe than is appropriate for...
One of the fundamental questions in insect evolution is the origin of their wings and primary function of ancestral wing precursors. Recent phylogenomic and comparative morphological studies broadly support a terrestrial ancestor of pterygotes, but an aquatic or semiaquatic ancestor cannot be ruled out...
