Subspecies and Distribution. H.a.aquaticusOgilby,1841—WAfricafromGuineaandSierraLeonetoGhana. H.a.bates:Lydekker,1906—Nigeria,Cameroon,andpresumablyneighboringcountries. H. a. cottoni Lydekker, 1906 — Republic of the Congo, DR Congo, and presumably Uganda. The Water Chevrotain reportedly has a disjunct distribution, occurring in coastal forests from West Africa and in the rainforests of Central Africa from Nigeria to DR Congo, marginally entering Uganda. It has been listed for the following countries in Central Africa: Angola (Cabinda), Cameroon, Central African Republic, DR Congo, Equatorial Guinea, Gabon, Nigeria, Republic of the Congo, and Uganda (Semliki Valley). A record from Angola's Lunda Norte Province, near the Cassai River,is the southernmost record of the species. The species' status in some countries remains unclear. It is apparently absent from the Republic of Benin and Togo (but the speciesis listed as probable in the Ot Basin in Togo); its supposed occurrence in Guinea Bissau and Senegal remains unsupported by evidence. The species was listed for Sierra Leone, although its presence had been called into question. Photographic evidence seems to clarify that the species occurs in Sierra Leone. In 1850, a specimen was recorded from Gambia, but the present status of the species is unclear. Local people report the species from the Boké Préfecture in NW Guinea, which might be the northernmost area from which the species has been recently reported. Extensive field and market surveys there and in the southern Guinea savanna belt did notfind evidence for the species' presence. in Tragulidae

Top-k comparison between spatial regions with respect to species occurrence
<h1>Abstract</h1> <p>Indicative species allow in their abundance the classification of biotopes, a spatially limited area with adapted species. However, because species interact between biotopes, it is also interesting to group biotopes together that are functionally or spatially related to each other, called biotop complexes, leading to implications for nature conservation measures. The classification of biotop complexes poses some challenges, as appropriate methods are still lacking. Building on existing studies from Edler et al. 2016 and Pang et al. 2023 this study presents a new framework that supports the objective identification of indicative species in biotop complexes and enables the searchability of biotop complexes using a localized search engine. This novel approach of using a search engine allows for a finer granularity of resolution, as biotop complexes were not sorted into rigid classes, but individually compared to each other based on a similar indicator species composition, which allow a more precise adaption of nature conservation measures. As a proof of concept, this thesis therefore attempts to answer the question whether biotop complexes with a similar indicator species composition produce similar indicative species in the framework. To support this study, an example dataset was created based on biotop locations in the National Park Kellerwald-Edersee and plant species records from Becker, Frede, and Lehmann 1996 of the national park area. For the implementation, the national park area was divided into cells and in each cell the indicative species were grouped and determined by an indicator species analysis. The indicative species were stored in the search engine and thus allowed the search of cells and therefore biotop complexes by their indicative species. The results showed that the predictions of indicative species by the framework depended on the cell size, as the cell size affected properties such as the biotopes intersecting with the cell or the number of plant species found by the framework. The number of biotop complexes with similar biotop compositions, as well as the similarity of their framework predicted indicative species, also depended on the cell size, while the overall similarity of the indicative species in these biotop complexes tended to be low. Additionally as the creation of the example dataset and the determination of the indicative species show a huge influence on the predictive capabilities of the framework, this thesis offers connection possibilities for future research. This thesis provides a solid foundation upon which future research can be built. The next steps to optimize the various customization options provided by the framework and to determine the optimal cell size to increase the significance of the framework's predictions allowing the framework to support future nature conservation management.</p>
