Special Issue Information

Dear Colleagues,

The novel concept of behavioural instability and its implications for the definition of the individual personality is now well established. It has been recognized that there is a need for high level of accuracy of a distribution’s four parameters: 1) mean, 2) variance, 3) skewness, and 4) kurtosis. In particular, the skewness of a distribution and the mean’s distance from the median of the distribution are very relevant for the characterization of the degree of asymmetry of a distribution. These two parameters allow us to quantify the degree of asymmetry in terms of fluctuating asymmetry and directional asymmetry. The variance can be used to estimate the degree of phenotypic variability, which is also correlated with the degree of asymmetry. There is now a need to test the method of “Asymmetry Indexes- Behavioural Instability”, on studies with larger sample size from animals kept in captivity and/or model organisms under different environmental setups which can be controlled in the laboratory.

The increased capacity of monitoring animals for long time periods with new behavioural devices and software has increased the statistical power of behavioural studies.

This increased statistical power will make it possible to answer several unresolved questions, such as:

  1. Is behavioural instability heritable? If behavioural instability should have an evolutionarily significant effect, it needs to have a certain degree of heritability, and the heritability of behavioural instability can be quantified by making experiments involving animals from several generations.
  2. Is behavioural instability maternally inheritable? Transgenerational effects like maternal effect could also be quantified.
  3. Is behavioural instability determined by a genotype × environment interaction? The use of clonal organisms could remove the bias due to the genetic variation between individuals and make it possible to quantify to what degree the genetic differences between individuals can determine differences in the degree of behavioural instability. In addition, it would also make it possible to discover to what degree differences between individuals in the degree of behavioural instability vary across environments.
  4. There are also practical application aspects that should be investigated further. For example, is it conceivable that behavioural instability is crucial for the understanding of behavioural results obtained from animal models?

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Symmetry is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
