Fluctuation domains in adaptive evolution [PDF]

Theoretical Population Biology, 2010
We derive an expression for the variation between parallel trajectories in phenotypic evolution, extending the well known result that predicts the mean evolutionary path in adaptive dynamics or quantitative genetics. We show how this expression gives rise to the notion of fluctuation domains - parts of the fitness landscape where the rate of evolution ...

Adaptive Evolution on Neutral Networks [PDF]

Bulletin of Mathematical Biology, 2001
We study the evolution of large but finite asexual populations evolving in fitness landscapes in which all mutations are either neutral or strongly deleterious. We demonstrate that despite the absence of higher fitness genotypes, adaptation takes place as regions with more advantageous distributions of neutral genotypes are discovered.

From transmission to adaptive evolution: genomic surveillance of Getah virus [PDF]

Frontiers in Cellular and Infection Microbiology
Getah virus (GETV) is a member of the Alphavirus of the Togaviridae. It is a single-stranded positive-RNA virus that is mainly transmitted by mosquitoes.

Microbial adaptive evolution [PDF]

Journal of Industrial Microbiology and Biotechnology, 2021
Abstract Bacterial species can adapt to significant changes in their environment by mutation followed by selection, a phenomenon known as “adaptive evolution.” With the development of bioinformatics and genetic engineering, research on adaptive evolution has progressed rapidly, as have applications of the process.

Behavioural variability among captive African elephants in the use of the trunk while feeding [PDF]

PeerJ, 2020
The Proboscideans, an order of mammals including elephants, are the largest of the Earth lands animals. One probable consequence of the rapid increase of their body size is the development of the trunk, a multitask highly sensitive organ used in a large ...

The relationship between distal trunk morphology and object grasping in the African savannah elephant (Loxodonta africana) [PDF]

PeerJ, 2022
Background During reach-to-grasp movements, the human hand is preshaped depending on the properties of the object. Preshaping may result from learning, morphology, or motor control variability and can confer a selective advantage on that individual or ...

Understanding patterns of taxonomic diversity, functional diversity, and ecological drivers of fish fauna in the Mekong River

Global Ecology and Conservation, 2021
Understanding different facets of biodiversity patterns and their ecological drivers are essential for freshwater conservation. This is especially true for fish fauna in the Mekong River, one of the largest rivers in the world, which faces large-scale ...

TRPV3: Structure, Diseases and Modulators

Molecules, 2023
Transient receptor potential vanillin 3 (TRPV3) is a member of the transient receptor potential (TRP) superfamily. As a Ca2+-permeable nonselective cation channel, TRPV3 can recognize thermal stimulation (31–39 °C), and it plays an important regulatory ...

Evolution by Adapting Surrogates [PDF]

Evolutionary Computation, 2013
To deal with complex optimization problems plagued with computationally expensive fitness functions, the use of surrogates to replace the original functions within the evolutionary framework is becoming a common practice. However, the appropriate datacentric approximation methodology to use for the construction of surrogate model would depend largely ...
