Background. The capacity of species to respond and perceive visual signal is integral to their evolutionary success. Giraffe is closely related to okapi, but the two species have broad range of phenotypic differences including their visual capacities. Vision studies...

We evaluate the population genetic structure of the intertidal barnacle Jehlius cirratus across a broad portion of its geographic distribution using data from the mitochondrial cytochrome oxidase I (COI) gene region. Despite sampling diversity from over 3000km...

Cytochrome C Oxidase Subunit 1 (COX1) is a protein that helps to catalyze the reduction of water into oxygen in Eukaryotes. Through the analyzation of COX1 from online public genetic databases in 16 species of fish, an evolutionary phylogeny of fish was derived...

Nuclear transfer techniques (a.k.a. mitochondrial replacement therapies) are currently under development to provide a route to eliminating particular instances of mitochondrial disease from the germline. Before these kinds of techniques are implemented clinically...

Many animal species use acoustic signals for social communication including attracting mates, defending resources and assessing risks. Nevertheless, a variety of ambient noise sources often interfere with sound communication and efficient decision making. In the...

A large array of species and species complexes from the Iberian Peninsula display strong genetic subdivisions indicative of past population isolation in separate glacial refugia as a result of survival throughout the Pleistocene ice ages. We used mitochondrial...

Reconstructing the timescale of the Tree of Life is one of the principal aims of evolutionary biology. This has been greatly aided by the development of the molecular clock, which enables evolutionary timescales to be estimated from genetic data. In recent years,...

Background. Shugoshins (SGOs) are proteins that protect cohesins located at the centromeres of sister chromatids from their early cleavage during mitosis and meiosis in plants, fungi, and animals. Their function is to prevent premature sister-chromatid disjunction...

Little is known about the factors driving within species Genome Size (GS) variation. GS may be shaped indirectly by natural selection on development and adaptative traits. Because GS variation is particularly pronounced in maize, we have sampled 83 maize inbred...

Chimpanzees have the largest relative brain size, greatest reproductive output, and longest lifespan of any non-human ape; they also have the highest level of physical activity in the wild, as measured by daily walking and climbing distances. In this study, we...

Studies documenting Human-Induced Rapid Evolutionary Change (HIREC) routinely compare contemporary allele or morph frequency distributions with historical baselines. All too often, this involves the re-sampling of a population that was sampled at a single time...
