WebNov 17, 2024 · While phenotypic convergence for long generation is decided by genetic evolutionary constraints in the adaptive evolution dynamics, other factors may be more important in the convergence of phenotypes in the short term by gene expression rather than genetic evolution. One explanation of these results is that there is selective pressure … WebAmong these genetic mechanisms, the same amino acid changes in protein-coding genes play an important role in adaptive phenotypic convergence. Methods for detecting adaptive convergence at the protein sequence level have been constantly debated and developed. Here, we review recent progress on using genomic approaches to evaluate the genetic ...
WebJul 22, 2014 · Phenotypic convergence is diagnosed when independent lineages share a common optimum. We found that the SURFACE algorithm can occasionally lead to incorrect inference of phenotypic regimes for certain lineages on account of the order dependence induced by the forward stepwise procedure. WebDec 27, 2024 · The method works by computing the angle between the phenotypic vectors of the species as a measure of their similarity and allows identification of the clades (rather than just the species) that converge. We show through simulations that search. conv is remarkably powerful and fast.
WebThis analysis revealed that resistant strains are divided into four groups that are positioned in different regions of PCA (Figure 2A), highlighting the convergence toward specific phenotypic states in response to antibiotic exposure. β-lactams, aminoglycoside, quinolone, and polymyxin antibiotics are commonly applied for the treatment of lung ...

WebEvolutionary convergence is a core issue in the study of adaptive evolution, as well as a highly debated topic at present. Few studies have analyzed this issue using a "real-time" or evolutionary trajectory approach. Do populations that are initially differentiated converge to a similar adaptive state when experiencing a common novel environment? green sand down to earthWeb1 Introduction. As a fundamental concept for dynamic component of the climate system, resilience is typically defined as the ability of individual trees, forests or ecosystems to resist sudden disturbances and recover to their initial state (Holling, 1973; Simoniello et al., 2008).Given the large potential of vegetation to take up atmospheric carbon dioxide and … fm0abe0000 base 2015WebStudying phenotypic convergence (the independent evolution of similar traits in different organisms) provides an opportunity to address evolutionary predictability at different hierarchical levels.
