Fig. 1 in Spatial genetic structure in the vulnerable smooth-coated otter (Lutrogale perspicillata, Mustelidae): towards an adaptive conservation management of the species
Fig. 1. Lutrogale perspicillata distribution (in yellow; see insets for Iraq and Pakistan) including sampling localities of modern (white circles) and museum (green squares) individuals. As far as the latter are concerned, we reported only sites for which samples were successfully investigated (see Table S1 for the entire sample size of this study; symbol "?" stands for unknown locality). The white stars indicate, in Iraq, the locality (TaqTaq, Kurdistan) where the sample of Omer et al. (2012) was collected, in Cambodia/Thailand and Malaysia, the country/ies of origin of EF472348 and KY117557 GenBank sequence, respectively. In Iraq, Pakistan, and supposedly Java, Indonesia, the green squares indicate localities (when known) of L. p. maxwelli, L. p. sindica, and L. p. perspicillata museum holotypes, respectively. Finally, Naga Hills at the border between Myanmar and India as well as Bahoo-Kalat River Basin between Iran and Pakistan are indicated (see text for more details). The species' geographic range was adapted from IUCN (International Union for Conservation of Nature) 2015. Lutrogale perspicillata. The IUCN Red List of Threatened Species 2019-3 was modified using CorelDraw!12 (2003). Digital images (insets) were obtained from Google Earth 7.1.5.1557 (2015 Google Inc.) and Google Earth map data (Data SIO, NOAA, U.S. Navy, NGA, GEBCO - Image Landsat). Please note that thick dotted lines mark out new borders for L. p. sindica and L. p. perspicillata subspecies as established in this study (see text for more details).

Niche conservation in copepods between ocean basins
<p>This dataset provides the necessary data to test for niche conservatism as demonstrated in the article "Niche conservatism in copepods between ocean basins; 10.1111/ecog.05690". </p> <p>Our study examined niche conservatism (i.e. a species' niche remains stable in space and time) between populations of the same species of marine copepod in different ocean basins. We used two approaches to test for niche conservatism which can be defined as a Princpial Component Analysis (PCA) and Environmental Niche Model (ENM) method. Niches may differ by virtue of the fact that the available environmental conditions do not overlap. This can be addressed by first establishing a baseline or a null model that quantifies how far a niche would be expected to differ by chance based on the environmental conditions in both areas. We used six environmental variables to define the environmental niche (sea surface temperature - SST °C, Salinity, mixed layer depth - MLD (m), bathymetric depth (m), chlorophyll-<em>a</em> - chl-<em>a</em> (mg m<sup>-3</sup>) and wind stress (N m-2).</p> <p>The PCA method uses the first 3 principal components to define the species niche in each population and the available background conditions in each area. If the niche distance between two populations is found to be significantly LESS than the distance in mean background conditions then the niches are judged to be conserved even if they are different. In contrast, if the niche distances are significantly different and MORE than the distance in mean background conditions then the niches are judges to be diverged. </p> <p>The ENM method compares the niches of two populations by using Maximum Entropy modelling (MaxEnt) to first define each popultions distributions across the environmental gradients. The niche overlap between two different populations were quantified using the Schoener's D metric where 0 = no niche overlap to 1 = full niche overlap. To separate the effect of different background conditions on the level of niche overlap (D), a null distribution (H<sub>0</sub>) was generated for each population by<br> calculating the differences between 100 ENMs generated using the presence data of one population and random background samples from the other population. If H<sub>0</sub> < D, the niches overlap greater than would be expected purely by chance and are therefore conserved. In contrast If H<sub>0</sub> > D the niches overlap less than would be expected by chance and are therefore diverged.</p> <p>Of the 21 pairwise comparisons between populations of the same species a total of 10 showed evidence of niche divergence. The divergent popaultions belonged to 7 of the 15 marine copepod species with the majority belonging to the genus <em>Pleuromamma. </em>The findings have important implicatons on the use of ecological models in defining the niche of marine copepods as regional populations may respond differently to environmental pressures.<em> </em>Evidence of strong genetic variation has been shown for many of these species with the potential for adaptive evolutionary response to regional pressures at a much faster rate than expected. Given this fact we encourage future studies to incorporate phylogenetic information into niche model analyses for plankton.</p>
