Figure 4 in Dung beetle conservation in a heterogeneous landscape of the Maputaland Centre of Endemism
Figure 4. Contribution of each spatial component (habitat and patch size) to total species numbers sampled in the entire reserve (gamma diversity, n = 61 species); alpha (α) = diversity contributed by study sites; beta (β1) = diversity between study sites; beta (β2) = diversity between habitats. Proportions contributed by alpha and beta diversity are shown by the divisions within the bars whereas numbers of species are shown inside the bars (see methods). DF = dune forest; SF-L, SF-M, SF-S = large, medium and small sand forest patches; G = grassland.
Figure S1 in Dung beetle conservation in a heterogeneous landscape of the Maputaland Centre of Endemism
Figure S1. Rarity index values for each species ranked from highest to lowest. Dotted lines show rare species found at up to two sites and indicate the high proportion of the total species (~60%) found at eight sites or less (key to blocks of species numbers in Table S1; species in bold biased to grassland occurrence).
Figure 3 in Dung beetle conservation in a heterogeneous landscape of the Maputaland Centre of Endemism
Figure 3. Box plots comparing number of species (A) and abundance (B) in each habitat type (DF = dune forest, SF-L, SF-M, SF-S = large, medium and small sand forest patches, G = grassland). Within each box, the mid-line represents the median whereas the lower and upper extents of the box represent the interquartile range Q1 = 25th percentile and Q3 = 75th percentile, respectively. Whiskers are minimum and maximum values. Black points represent outliers. Different letters indicate statistical differences at P <0.05.
Figure 2 in Dung beetle conservation in a heterogeneous landscape of the Maputaland Centre of Endemism
Figure 2. Frequency distribution for proportions of species recorded at 32 study sites in MSR (n = 4 in dune forest; n = 7 in grassland and each of three patch sizes of sand forest). Dotted lines delineate the relative incidence of rar- er species at study sites. Note that a high percentage of the total species are found only in 25% of the sampled sites. See Figure S1 for values of the species rarity index.
Figure 1. A in Dung beetle conservation in a heterogeneous landscape of the Maputaland Centre of Endemism
Figure 1. A, map outlining the study area and showing the position of Maputo Special Reserve (MSR) in relation to land usage in the surrounding area of southeast Mozambique and northeast KwaZulu-Natal, South Africa (nature and game reserves are marked by green and yellow, darker grey outlines the Lubombo Conservancy, unprotected areas are pale grey, Indian Ocean, inlets and lagoons are blue) (redrawn from Peace Parks Foundation 2020); B, position of sampling localities in MSR plotted onto Google Earth; L1–L7 = study sites at each locality in large, medium and small sand forest patches plus grassland; L8, DF1–DF4 = dune forest study sites. Position of most forest sites was measured at the point of entry as the GPS could not detect satellites under the canopy.

Fig. 3 Canonical correspondence analysis. Only axes 1 and 2 are shown. Type 2 in Evaluating the correlation between area, environmental heterogeneity, and species richness using terrestrial isopods (Oniscidea) from the Pontine Islands (West Mediterranean)
Fig. 3 Canonical correspondence analysis. Only axes 1 and 2 are shown. Type 2 scaling is shown. A right-angled projection of a point representing a response variable (ecological categories of species) onto an arrow representing an explanatory variable (biotope type)
Fig. 2 in Evaluating the correlation between area, environmental heterogeneity, and species richness using terrestrial isopods (Oniscidea) from the Pontine Islands (West Mediterranean)
Fig. 2 Path analysis model. In this model, species richness (S) is the dependent variable. Area (A) and environmental heterogeneity (H) can have a direct effect on S, whereas A can also have an effect on H. The indicators used for A and S are the log-transformed area in square kilometres (LogA) and the number of species (LogS). Different indicators were used for environmental heterogeneity (B, LogB, Shannon, and 1-D, see main text). The symbols bAS, bAH, and bHS indicate the partial standardised regression coefficients

Heterogeneous Integrated Dataset for Maritime Intelligence, Surveillance, and Reconnaissance
<p>Facing an increasing amount of movements at sea and daily impacts on ships, crew and our global ecosystem, many research centers, international organizations, industrials have favored and developed sensors, detection techniques for the monitoring, analysis and visualization of sea movements. Automatic Identification System (AIS) is one of these electronic systems that enable ships to broadcast their dynamic (position, speed, destination...) and static (name, type, international identifier…) information via radio communications.</p> <p>Having spatially and temporally aligned maritime dataset relying not only on ships' positions but also on a variety of complementary data sources is of great interest for the understanding of maritime activities and their impact on the environment.</p> <p>This dataset contains ships' information collected though the Automatic Identification System, integrated with a set of complementary data having spatial and temporal dimensions aligned. The dataset contains four categories of data: Navigation data, vessel-oriented data, geographic data, and environmental data. It covers a time span of six months, from October 1st, 2015 to March 31st, 2016 and provides ships positions within Celtic sea, the Channel and Bay of Biscay (France). The dataset is proposed with predefined integration and querying principles for relational databases. These rely on the widespread and free relational database management system PostgreSQL, with the adjunction of the PostGIS extension, for the treatment of all spatial features proposed in the dataset.</p>
