Vertigo angustior JEFFREYS 1830

<i>Vertigo angustior</i> JEFFREYS 1830 (Tab. 3) <p>Currently there is a lack of information about the population size and abundance of this species in Slovakia. Despite the fact, the criterion C1 was evaluated as "good" because of the relatively widespread distribution of the species in Slovakia. Even though a low weight (2 or 1) was appointed for the criterion C1. The criterion C2 (Habitats) was evaluated as "good" from the habitat status point of view and "average" concerning the water regime because of the long-term decreasing of numbers of suitable wetland habitats within Slovakia, generally.</p> <p> <i>V. angustior</i> is listed as vulnerable (VU) in the National Red List of Molluscs of Slovakia (ŠTEFFEK & VAVROVÁ 2006), which was prepared in 2006 under the categories and criterion of IUCN, version 3.1 (2001).</p>Published as part of <i>Vavrová, Ľ. & Šteffek, J., 2007, Favourable conservation status of European important species of genus Vertigo spp. in Slovakia - categories and criteria, pp. 667-676 in Linzer biologische Beiträge 39 (1)</i> on page 671, DOI: <a href="http://zenodo.org/record/5412309">10.5281/zenodo.5412309</a&gt

Determination of ecological significance based on geostatistical assessment: a case study from the Slovak Natura 2000 protected area

Abstract: The Sitno Natura 2000 Site covers an area of 935,56 hectares. The Sitno region is significant due to the number of rare and endangered species of plants, and as a result is considered a location of great importance to the maintenance of floral gene pools. The study area suffers human impacts in the form of tourism. The main purpose of this study is to the measure landscape elements, determine the ecological significance of habitats within the Sitno area, and from this data, organize the study area into conservation zones. The results of this landscape quantification are numerical values that can be used to interpret the quality of ongoing ecological processes within individual landscape types. Interpretation of this quantified data can be used to determine the ecological significance of landscapes in other study areas. This research examines the habitats of Natura 2000 Sites by a set of landscape metrics for habitat area, size, density, and shape, such as Number of patches (NP), Patch density (PD), Mean patch size (MPS), Patch size standard deviation (PSSD) and Mean shape index (MSI). The classification of land cover patches is based on the Annex Code system.M. Klauco, B. Gregorová, P. Koleda, U. Stankov, V. Markovic, and P. Lemenkova.
