Our objective was to analyze the spatial patterns of arthropod assemblages along a gradient of different stabilization levels, which represents the different stages of dune stabilization &#8211; from the shifting crest of the dune to the stabilized crusted interdune.<\/p>\n<p>The study was carried out at the sand dunes of the North-Western Negev in Israel. Data was collected using dry pitfall traps over two consecutive years during the<\/p>\n<p>spring along northern windward aspects. Four dunes were chosen, characterized by three signifi cant landscape units: shifting crest, semi-stabilized slope and stabilized<\/p>\n<p>interdune.<\/p>\n<p><strong>Results: <\/strong>We identified three significant assemblages of arthropods along the gradient. The shifting dune crests are populated by psammophilic species found<\/p>\n<p>almost exclusively in sandy habitats in Egypt and the western Negev in Israel. The crusted, stabilized inter-dunes are populated mainly by loess-dwelling species, which<\/p>\n<p>are common in most of the Negev loess plains and have a wide distribution range, and the semi-stabilized slopes host species of both extreme landscape units but is<\/p>\n<p>distinguished by four species that show significant affinity to it.<\/p>\n<p><strong>Conclusions: <\/strong>Our results demonstrate functional arthropod heterogeneity and emphasize the risk of regional species homogenization. Heterogeneity is a key property in maintaining sand dune biodiversity. Homogenization, as a result of sand stabilization, may lead to loss of psammophilic species.<\/p>\n<figure style=\"width: 960px\" class=\"wp-caption alignnone\"><img fetchpriority=\"high\" decoding=\"async\" class=\"wp-image-6066 size-full\" src=\"https:\/\/www.adssc.org\/en\/wp-content\/uploads\/2020\/11\/ELLI-\u05d3\u05d9\u05d5\u05e0\u05d4.jpg\" alt=\"\" width=\"960\" height=\"450\" srcset=\"https:\/\/www.adssc.org\/en\/wp-content\/uploads\/2020\/11\/ELLI-\u05d3\u05d9\u05d5\u05e0\u05d4.jpg 960w, https:\/\/www.adssc.org\/en\/wp-content\/uploads\/2020\/11\/ELLI-\u05d3\u05d9\u05d5\u05e0\u05d4-600x281.jpg 600w, https:\/\/www.adssc.org\/en\/wp-content\/uploads\/2020\/11\/ELLI-\u05d3\u05d9\u05d5\u05e0\u05d4-300x141.jpg 300w, https:\/\/www.adssc.org\/en\/wp-content\/uploads\/2020\/11\/ELLI-\u05d3\u05d9\u05d5\u05e0\u05d4-768x360.jpg 768w\" sizes=\"(max-width: 960px) 100vw, 960px\" \/><figcaption class=\"wp-caption-text\">The sampled landscape units along a vegetation and altitude transect of about 500 m long: shifting crest, semi-stabilized northern slope and stabilized interdune.<\/figcaption><\/figure>\n<p>&nbsp;<\/p>\n<figure id=\"attachment_6065\" aria-describedby=\"caption-attachment-6065\" style=\"width: 908px\" class=\"wp-caption alignnone\"><img decoding=\"async\" class=\"wp-image-6065 size-full\" src=\"https:\/\/www.adssc.org\/en\/wp-content\/uploads\/2020\/11\/ELLI-\u05d2\u05e8\u05e3-\u05de\u05e9\u05d5\u05dc\u05e9.png\" alt=\"\" width=\"908\" height=\"967\" srcset=\"https:\/\/www.adssc.org\/en\/wp-content\/uploads\/2020\/11\/ELLI-\u05d2\u05e8\u05e3-\u05de\u05e9\u05d5\u05dc\u05e9.png 908w, https:\/\/www.adssc.org\/en\/wp-content\/uploads\/2020\/11\/ELLI-\u05d2\u05e8\u05e3-\u05de\u05e9\u05d5\u05dc\u05e9-600x639.png 600w, https:\/\/www.adssc.org\/en\/wp-content\/uploads\/2020\/11\/ELLI-\u05d2\u05e8\u05e3-\u05de\u05e9\u05d5\u05dc\u05e9-282x300.png 282w, https:\/\/www.adssc.org\/en\/wp-content\/uploads\/2020\/11\/ELLI-\u05d2\u05e8\u05e3-\u05de\u05e9\u05d5\u05dc\u05e9-768x818.png 768w\" sizes=\"(max-width: 908px) 100vw, 908px\" \/><figcaption id=\"caption-attachment-6065\" class=\"wp-caption-text\">Affinity triangular: The percentage of abundance in each landscape unit for each species (given as a circle with a number).
