Special Issue Information

Dear Colleagues,

This Special Issue aims to explore the remarkable diversity of sensory systems in mammals, stemming from their adaptations to a variety of environmental conditions. Contributions are invited that explore the morpho-functional, physiological, genomic, ecological, and evolutionary bases that define the unique sensory traits of mammals. By extending the scope beyond traditional sensory research, this Special Issue seeks to spotlight groundbreaking studies that reveal how various habitats influence the sensory capabilities of mammals. We encourage submissions on complex sensory adaptations that have allowed mammals to successfully occupy diverse ecological niches.

Contributions should aim to enhance our understanding of sensory evolution and functionality across the mammalian clade. Furthermore, it is crucial to equally address the interactions among different sensory systems, as understanding these interactions can provide deeper insights into the integrative nature of sensory inputs in mammals. We aim to expand the boundaries of knowledge in sensory biology and encourage submissions in underexplored or traditionally overlooked areas such as ultrasound detection, visceral sensory mechanisms, electroreception, and chemosensory communication.

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 250 words) can be sent to the Editorial Office for assessment.

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-anonymized 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.

The vomeronasal system (VNS) is directly linked to the various behavior and ecology of all animal species, and understanding it might help to prevent deer damage. We therefore histochemically analyzed the accessory olfactory bulb (AOB) and the vomeronasal organ (VNO) that, respectively, function as a primary integrative center and a peripheral receptor organ, in Hokkaido sika deer (Cervus nippon ssp. yesoensis). The AOB consisted of the vomeronasal nerve, glomerular, plexiform, and granule cell layers. We found that G protein α subunit i2 (Gαi2) and o (Gαo) that are, respectively, coupled with vomeronasal receptor type 1 and 2 families were strongly and weakly expressed in the glomerular layer, respectively. These properties of the AOB of sika deer were similar to those of other artiodactyl species, including wapiti. We then explored the sika deer VNO using 21 lectins that bind to each glycan structure. Although various cell types in the VNO had unique lectin binding profiles, all 21 lectins bound to the free border of the sensory epithelium, suggesting that various glycoconjugates are involved in pheromone detection in sika deer via the VNO. Furthermore, the reactivity of some lectins in the sensory epithelium and vomeronasal gland differed from those of roe deer and wapiti. Our findings suggest that the composition of glycoconjugates in the VNO differs among deer species. Full article
