Figure 3 in Well-known species, unexpected results: high genetic diversity in declining Vipera ursinii in central, eastern and southeastern Europe

Figure 3. Genetic relationship between locations calculated using Cavalli-Sforza and Edwards Dc distance (Cavalli-Sforza and Edwards, 1967) using the software POPULATIONS 1.2.28 (Langella, 1999). The distances were calculated with 5 microsatellite markers and branches with bootstrap support>40 were indicated.

Figure 2 in Well-known species, unexpected results: high genetic diversity in declining Vipera ursinii in central, eastern and southeastern Europe

Figure 2. Maximum-likelihood tree from combined data (Cytochrome b and ND4, totalling 1920 bp) for different subspecies of Vipera ursinii. Values of bootstrap support for maximum likelihood (first) maximum parsimony (middle) are shown for nodes found in more than 50% of 1000 trees, as well as posterior probability from Bayesian inference (right). The population number (see fig. 1 and supplementary table S1) where the haplotypes have been found are added to the haplotype label. Drawing of Vipera ursinii rakosiensis courtesy of Márton Zsoldos.

Figure 1 in Well-known species, unexpected results: high genetic diversity in declining Vipera ursinii in central, eastern and southeastern Europe

Figure 1. Location of the samples used in the study: squares represent mtDNA data, round symbols represent microsatellites data. The size of the round symbols is proportional to the number of samples used. Locality numbers correspond with supplementary table S1 (in black when microsatellite data are available; in white when mtDNA data). The colours of the marks are different between subspecies: green: V. ursinii rakosiensis, yellow: V. u. moldavica, blue: V. u. macrops, grey: V. u. macrops from Bistra Mt., red: V. renardi. White striped grids show distribution of each subspecies/species on a 100x100 UTM grid resolution (after Sillero et al., 2014). Distribution area of V. greaca (from IUCN red list, Mizsei et al., 2018) is colored in pink. On the top left, insert A shows a zoom in the V. ursinii macrops region, while insert B illustrates the location of study area within Europe.

Figure 4. Comparative phylogenetic relationship between the 11 in Well-known species, unexpected results: high genetic diversity in declining Vipera ursinii in central, eastern and southeastern Europe

Figure 4. Comparative phylogenetic relationship between the 11 regions with both mtDNA (left) and nDNA (right). left: Mitochondrial DNA tree based on the genetic distances of the different haplotypes (combining cytochrome b and ND4; 1920 bp) within each region. right: Nuclear tree based on Cavalli-Sforza and Edwards Dc distances (Cavalli-Sforza and Edwards, 1967) calculated with the software POPULATIONS 1.2.28 (Langella, 1999) based on 5 microsatellites markers. Dashed branches correspond to discrepancies between both phylogenetic reconstructions. Both trees were not rooted. The colours are different between subspecies: green: V. ursinii rakosiensis, yellow: V. u. moldavica, blue: V. u. macrops, grey: V. u. macrops from Bistra Mt., red: V. renardi.

Predicting species richness and diversity using satellite remote sensing and random forest machine learning algorithm

<p><strong>Aims</strong>: Remote sensing approaches could be beneficial for monitoring and compiling essential biodiversity data because it is cost-effective and allows for coverage of large areas over a short period. This study investigated the relationship between multispectral remote sensing data from Landsat 8 and Sentinel 2 and species richness and diversity in mountainous and protected grasslands.</p> <p><strong>Locations</strong>: Golden Gate Highlands National Park, Free State, South Africa. </p> <p><strong>Methods</strong>: In-situ data of plant species composition and cover from 142 plots with 16 releves each were distributed across the study site and used to calculate species richness and Shannon-wiener species diversity index (species diversity. We used a machine-learning random forest algorithm to optimise the prediction of species richness and diversity. The algorithm was used to identify the optimal spectral bands and vegetation indices for estimating species richness and diversity. Subsequently, the selected bands and vegetation indices were used to estimate species richness through random forest regression. </p> <p><strong>Results</strong>: This research found weak relationships between remote sensing vegetation indices and the diversity metrics, but significant relationships were found between some spectral bands and diversity metrics. Moreover, using machine learning random forest, the multispectral datasets exhibited strong predictive powers. In this investigation, for both sensors, near-infrared (NIR) seemed to be the most selected band to explain species diversity in mountainous grasslands.</p> <p><strong>Main</strong> <strong>conclusions</strong>: This finding further ascertains the efficiency of using NIR in vegetation mapping.  This research shows that NIR, SAVI and EVI are the most adequate for predicting species richness and diversity in mountainous grasslands with relatively good accuracies.</p>
