New data on the spider fauna (Araneae) of Navarre, Spain: results from the 7^thEDGG Field Workshop

Abstract

Multi-taxon investigations are of great importance in biodiversity research. We sampled spiders during the 7 th EDGG Field Workshop aimed at studying dry grassland diversity in Navarre, Spain. A total of 99 spider species from 15 families were recorded from 14 localities. Of these, 47 species were new to Navarre. To date, the list of spiders of Navarre accounts for 322 species. During this first dry grassland-specific study of spiders in Spain, 78 species were recorded for the first time in this type of habitat in Navarre, and for 69 species it is a newly recorded habitat in the Iberian Peninsula. The grasslands growing in the submediterranean humid and supramediterranean upper dry territories, belonging to Festuco-Brometea and Festuco-Ononidetea phytosociological classes, were the richest in terms of inhabiting spiders (26 and 23 species respectively) while the communities of mesomediterranean semi-arid area (Lygeo-Stipetea and Salicornietea fruticosae classes) were the poorest (four species each).

“…In general, all terricolous vascular plants, bryophytes and lichens are recorded in the plot. Additionally, sporadically we also sample other taxa: spiders, orthopterans, leafhoppers, butterflies, fungus gnats(Filibeck et al 2018;Polchaninova et al 2018;Aleksanyan et al 2020;Magnes et al 2020; Moysiyenko et al 2022).Past Field Workshops already resulted in numerous scientific publications, devoted to the questions of biodiversity patterns, syntaxonomical issues, floristic findings, etc. (e.g.,Kuzemko et al 2016; Polyakova et al 2016;Magnes et al 2020;Dembicz et al 2021a;García-Mijangos et al 2021;Bergauer et al 2022).…”
