Cryptic diversity in <i>Ptyodactylus</i> (Reptilia: Gekkonidae) from the northern Hajar Mountains of Oman and the United Arab Emirates uncovered by an integrative taxonomic approach - Fig 4

<p><b>Visualization of the climatic space occupied by <i>Ptyodactylus orlovi</i> (1) and <i>Ptyodactylus ruusaljibalicus</i> sp. nov. (2) based on PCA-env (A) and ENFA (B).</b> (A) The niches of both species are displayed on a multi-dimensional scale represented by the first two axes of a principal component analyses (PCA) summarizing the entire study area. (B) The x-axis shows marginality and the y-axis specialization. In both figures the grey shadings reflect the density of the occurrences of each species by cell. The dashed and solid contour lines illustrate, respectively, 50% and 100% of the available background environment. The significance of the equivalency and similarity tests is shown with an asterisc (*).</p

L'ABC della relatività

Tutti sanno che Einstein cambiò un capitolo della storia del pensiero umano quando scoprì la teoria della relatività, ma poci hanno le idee chiare in proposito..

Principal Component Analysis (PCA) of the climatic space of Oman (grey dots) using 12 BIOCLIM variables.

<p>Dashed lines delimit the climatic clusters that group 10% of the explained variance by PC1 and PC2. Green dots represent the climatic space of protected areas.</p

Number of species displayed in a cumulative way.

<p>Dots represent the years with species descriptions. Dashed lines divide the graph into intervals of 20 years. The last dot includes the species in the process of being described.</p

Percentage of the species’ distribution area included within a protected area.

<p>Dashed lines indicate the conservation target of 17% and 12% of the total species’ distribution area within a protected area. (A) The extent of species occurrence was defined using the presence-absence in every pixel of 1 km x 1 km. (B) The extent of species occurrence was defined using a minimum convex polygon (MCP) of the observations filtered by the species’ average altitude.</p

Map of Oman indicating the sampling effort.

<p>Grids of 10 arc-minutes (~18km) with observations (red dot). Empty grid cells are either due to no observation or no sampling.</p
