“…Especially, it seems likely that some of the Mediterranean areas are insufficiently investigated due to low sampling efforts in these areas (e.g. Sardinia, parts of the Balkan Peninsula; Deltshev 2004). In contrast, in Western, Northern and Central Europe knowledge on spider species richness seems to be quite good, although species lists are still being extended as new species are encountered in certain areas, or due to nomenclatural changes.…”

Macroecological patterns of spider species richness across Europe

We analysed the pattern of covariation of European spider species richness with various environmental variables at different scales. Four layers of perception ranging from single investigation sites to the whole European continent were selected. Species richness was determined using published data from all four scales. Correlation analyses and stepwise multiple linear regression were used to relate richness to topographic, climatic and biotic variables. Up to nine environmental variables were included in the analyses (area, latitude, elevation range, mean annual temperature, local variation in mean annual temperature, mean annual precipitation, mean July temperature, local variation in mean July temperature, plant species richness). At the local and at the continental scale, no significant correlations with surface area were found, whereas at the landscape and regional scale, surface area had a significant positive effect on species richness. Factors that were positively correlated with species richness at both broader scales were plant species richness, elevation range, and specific temperature variables (regional scale: local variation in mean annual, and mean July temperature; continental scale: mean July temperature). Latitude was significantly negatively correlated with the species richness at the continental scale. Multiple models for spider species richness data accounted for up to 77% of the total variance in spider species richness data. Furthermore, multiple models explained variation in plant species richness up to 79% through the variables mean July temperature and elevation range. We conclude that these first continental wide analyses grasp the overall pattern in spider species richness of Europe quite well, although some of the observed patterns are not directly causal. Climatic variables are expected to be among the most important direct factors, although other variables (e.g. elevation range, plant species richness) are important (surrogate) correlates of spider species richness.

In order to increase our arachnological knowledge of Greece, and in particular north-east Greece, an investigation of the arachnofauna of the Aladjagiola wetland complex was conducted from April to July 2008. The study area is part of the Nestos Delta in north-east Greece, and comprises an area of approximately 20 km 2 . Spiders were collected from 28 sites using pitfall traps. In all, 6694 specimens were sampled, including 206 species from 31 families. Altogether, 30 and 74 species were new to the districts of Greece and Macedonia, respectively. A number of faunistically interesting species were recorded during the study:

“…The importance of the Carpathians and Balkan Highlands as centers of diversification and endemism has been discussed for many groups of organisms, including plants (e.g., Trigas et al 2007, Hajek et al 2008, mammals (e.g., Griffiths 2002, Kotlik et al 2006), reptiles (Bohme et al 2007), leeches (Sket and Trontelj 2008), spiders (Deltschev 1999), and a wide array of insects including butterflies (Schmitt andHaubrich 2008, Varga 2008) and caddisflies (e.g., Botosaneanu 1973, 1975, Mey and Botosaneanu 1985, Balint et al 2008, Previšic et al 2009). …”
