Special Issue Information

Dear Colleagues,

Morphological characterization of animals and their organs provides unique information about their function, development, and how they have been shaped by evolution. In this Special Issue of Animals, we invite the submission of manuscripts that describe animal morphology from evolutionary and environmental perspectives. Examples of evolutionary works include but are not limited to fossil studies, comparative morphology, and functional morphology with a detailed discussion of its evolutionary aspects. The effect of environmental factors (e.g., temperature and contamination) on morphology is a typical example of the topic for environmental works, which comprises the field of histopathology. Interactions with other species is also considered to be an environmental factor.

We particularly welcome the submission of studies employing ultrastructural and immunohistochemical observations as well as those on samples that are difficult to obtain (e.g., the noninvasive observation of museum collections, approved studies on endangered species, and deep-sea animals). It is also important to apply state-of-the-art technologies such as magnetic resonance imaging (MRI), computerized tomography (CT), and artificial intelligence (AI; for data analysis), as they move the field of zoology forward beyond the conventional frame. A combination with nonmorphological data is acceptable as long as morphological characterization comprises the main body of the paper.

With your invaluable contributions, we hope that this Special Issue will be a useful opportunity to recall the intellectual excitement and importance of describing nature and biodiversity, which underlie the progressive development of modern biology.

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. Animals is an international peer-reviewed open access semimonthly 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 2400 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.

In this, work some aspects of the development of the visual system of Nothobranchius guentheri at the main stages of ontogenesis were described for the first time. It was possible to establish that the formation of the visual system occurs similarly to other representatives of the order Cyprinodontiformes, but significantly differs in terms of the individual stages of embryogenesis due to the presence of diapause. In the postembryonic period, there is a further increase in the size of the fish’s eyes and head, to the proportions characteristic of adult fish. The histological structure of the eye in adult N. guentheri practically does not differ from most teleost fish living in the same environmental conditions. The study of the structure of the retina showed the heterogeneity of the thickness of the temporal and nasal areas, which indicates the predominant role of peripheral vision. Morphoanatomical measurements of the body and eyes of N. guentheri showed that their correlation was conservative. This indicates an important role of the visual system for the survival of fish in natural conditions, both for the young and adults. In individuals of the older age group, a decrease in the amount of sodium (Na) and an increase in magnesium (Mg) and calcium (Ca) were found in the eye lens. Such changes in the elemental composition of the lens can be a sign of the initial stage of cataractogenesis and disturbances in the metabolism of lens fibers as a result of aging. This allows us to propose N. guentheri as a model for studying the structure, formation, and aging of the visual and nervous systems. Full article
