Special Issue Information

Dear Colleagues,

Hybridisation among related species is increasingly studied due to its role in the adaptation, evolution, and diversification of species. Habitat degradation and livestock translocation have been reported to promote hybridisation between domestic species and their wild counterparts. The effects of such genetic admixture can lead to very different consequences: they can provide adaptive features or lead to the erosion of genetic diversity; they can disrupt adaptation processes or introduce beneficial traits for survival or economic purposes.

We pose three main questions to approach such a multifaceted scenario:

  • How the livestock x wildlife interaction is going to affect the distribution and survival of wild species (competition/fertility/quality traits)?
  • Processes related to animal behaviour, ecological features or demography might influence the level of genetic diversity of populations. What are the genetic consequences of livestock x wildlife interaction?
  • How the livestock x wildlife interaction affects the distribution of diseases and survival of individuals (sensitivity/resistance)?

We welcome contributions related, but not limited, to the effect of wild x domestic interaction, in order to realise a Special Issue that extends on the current knowledge of the topic and will inspire future research.

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. Animals 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.

A wide range of mammalian hybrids has recently been found by chance or through population-screening programs, but studies about their fertilizing capacity remain scarce and incomplete. Most of them are assumed to be sterile due to meiotic arrest caused by the failure of chromosome pairings. In this study, we evaluated both sperm meiotic segregation, by 2D fluorescent in situ hybridization (FISH) analysis, and sperm quality (Sperm Chromatin Structure Assay) by flow cytometer in a fertile boar–pig hybrid (2n = 37,XY) originating from a Nero Siciliano pig breed (Sus scrofa domesticus) and a wild boar (Sus scrofa ferus). Spermatozoa were also separated by a dual-layer (75–60%) discontinuous Percoll gradient, resulting in two fractions with a significantly better overall quality in the motile sperm fraction. These data were confirmed by FISH analysis also, where the frequencies of spermatozoa with a regular chromosome composition were 27% in total sperm fraction and 64% in motile sperm fraction. We also evaluated the nuclear architecture in all counted spermatozoa, showing a chromatin distribution changing when chromosome abnormalities occur. Our results demonstrate that the chromosome pairing has a minimal effect on the sperm segregation and semen quality of a boar–pig hybrid, making it fertile and harmful for the conservation of autochthonous pig breeds.
