Special Issue Information

Dear Colleagues,

Endemic and threatened species are considered important by both scientists and politicians. Nature conservation concepts and measures require profound knowledge of evolutionary and ecological processes, as well as of the distribution patterns of biodiversity and threats to this diversity. Land-use change and the intensification of agriculture, forestry, and fisheries increase the pressure on ecosystems and their biota.

This Special Issue will focus on analyses of selected endemics or globally threatened species in relation to biogeography, landscape ecology, and genetics/taxonomy. The purpose is to generate scientific information on selected taxa as a fundament for political decisions related to ecosystems or special regions.

We thus welcome contributions on, for example, less-familiar mollusks or insects, as well as new insights on well-known vascular plants or vertebrates. This Issue focuses on taxa with a very restricted range or which are seriously threatened. In particular, we welcome submissions demonstrating how such studies have had an impact on policy (local, regional, or national).

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. 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 1400 CHF (Swiss Francs). We particularly encourage submissions from top researchers who may be under financial constraints. If you would like to apply for a discount, please submit a cover letter of interest for publication to the Editorial Office () and provide all authors' information and the abstract or proposal. We would provide a specific discount once the abstract/proposal gets approved by the office. Submitted papers should be well formatted and use good English.

Preference for Artificial Refugia over Natural Refugia in an Endangered Fish

The availability of appropriate refugia may ameliorate some impacts of habitat degradation and can aid in the conservation of target species. In addition to natural refugia, the provision of artificial refugia may be viable, particularly in degraded habitats. We examined the conservation potential of natural and artificial refugia for the endangered Eastern Cape redfin, Pseudobarbus afer. We show that deeper water is preferred so is likely to constitute a natural refuge. However, this preference is overridden by the provision of artificial refugia (a plastic pipe). We highlight that the most important habitat factor in the conservation of P. afer is availability of suitable natural refugia through avoidance of habitat destruction. However, when redfin habitat is already compromised, appropriate artificial refugia may supplement the protection provided by natural refugia and may provide benefits to the whole aquatic community.

Fawn Counts and Adult Female Site Use Are Mismatched Indicators of Habitat Quality in an Endangered Deer

Many ungulates are spotted as neonates. This trait is unique to individuals, making their identification feasible from remote cameras. Key deer (Odocoileus virginianus clavium) are an endangered subspecies of white-tailed deer endemic to the lower Florida Keys, U.S.A. Habitat loss and hunting were historical drivers of population decline but recent studies report positive associations of key deer with urbanization. Using opposing camera traps at 56 sites throughout the National Key Deer Refuge on Big Pine Key, we used spot patterns to uniquely identify and estimate fawn abundance with N-mixture models. We further compared those inferences to models informed by adult doe counts to see how well tracking adult females alone corresponded with fawn habitat associations. Our results indicated that fawn abundance was negatively associated with increasing elevation and human trails, contrary to models based on adult female observations alone. The lowest elevations where fawns were most abundant were associated with dense wetland plant communities, which were likely selected for thermal cover and warrant further investigation given that those areas are most vulnerable to sea-level rise. Our methods showcase the utility of identifying neonates from camera trap photos and draw attention to possible misaligned inferences when tracking adult females in isolation. Full article
