Special Issue Information

Dear Colleagues,

I cordially invite you to submit your research to this upcoming Special Issue on (ecto- and endo-) parasites and endosymbionts of the reptile world. In addition to your very appreciated contributions, suggestions of other potential contributors are very welcome. The more contributions made to this interesting Topic, the better.

Reptiles represent an important component of global vertebrate biodiversity. They are threatened by global change in both climate and land use. Some species are already disappearing or are expected to vanish soon. These ectotherms carry important infra-estimated components of invertebrate biodiversity: parasites and endosymbionts. Some are host-specialist and remain unknown to science, which makes them susceptible to disappearance before being revealed. This Special Issue aims to fill in this gap within knowledge and also elucidate some ecological interactions between this type of neglected diversity and reptile hosts.

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 submissions that pass pre-check are 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. Diversity 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 2100 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.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Vertebrates function as intermediate hosts for the last larval stages of metazoan parasites and as their definitive hosts where sexual reproduction takes place. In this work, the metazoans that parasitize the snake Thamnophis melanogaster in Laguna de Cuitzeo, Michoacán, were identified, and their infection parameters were calculated to determine the factors that determine the presence of the metazoan species found. A total of 24 snakes (20 adults and 4 neonates) were collected, but only the adults affected by parasitic metazoans were detected, accounting for 54.2% of the total sample. One trematode species, one nematode species, and one acanthocephalan species were found inside the snake. The cystacanth Polymorphus brevis (37.5%) and Contracaecum sp. (25%) stand out for their high prevalence. Ochetosoma brevicaecum and the pentastomids of the genus Porocephalus presented a low prevalence. Only O. brevicaecum uses T. melanogaster as a definitive host. The life cycles of the metazoan that parasitizes T. melanogaster suggest that the snake acquires the infection through active transmission by penetration or passive transmission by ingestion.
