Grassland patches embedded in an urban matrix can harbour a significant number of spider taxa, including rare and endangered species. To further benefit urban biodiversity, Karlsruhe was one of the first cities in Central Europe that adopted biodiversity friendly mowing regimes. The aim of this study was to investigate the effects of two mowing reg...

Although urbanisation is one of the greatest threats to biodiversity, its effect on particular invertebrate groups remains ambiguous on local and landscape scales. We aimed to analyse the effect of urban grassland management on spiders (Araneae) and carabids (Coleoptera: Carabidae), as well as other local and landscape parameters. We investigated 2...

Xysticus grallator Simon, 1932 is a little-known species of crab spider distributed in the western Medi-terranean region. We present new records of this species from mainland Italy, together with images of living and preserved specimens, the copulatory organs, and the habitat. A map of literature records provides insights into the known distributio...
Article
Full-text available
Urbanization has a major impact on biodiversity. For many organisms, the urbanization process means environmental stress caused by fragmentation and increased temperatures in cities and atmospheric, soil, light, and noise pollution. Such environmental stress can influence both the morphology and behavior of animals. Hence, individuals might be sele...
Article
Full-text available
Aim The continuous spread of invasive species is attributed to demographic processes and high dispersal rates. Both can change and evolve during range expansion, eventually accelerating spread dynamics. Here, we document such an accelerated spread for one of the most invasive spiders in Europe, the dwarf spider Mermessus trilobatus , and test wheth...
Article
The type material of Poecilochroa loricata Kritscher, 1996 is revised and the holotype is illustrated in detail.
Article
Full-text available
Philodromus poecilus (Thorell, 1872) is a Transeurasian species reported from most parts of Europe except the British Isles and the Iberian Peninsula. Although widely distributed, this species is extremely rarely recorded in Germany and neighbouring countries. In Bavaria, it has not been found since the time of Ludwig Koch (1825–1908). Recently, se...
Article
Full-text available
Macrothele calpeiana (Walckenaer, 1805) is among the largest and most remarkable European spiders. The species is frequently introduced to areas outside its natural distribution by the ornamental plant trade, a major vector for alien species. Two further imports of this species are presented in this paper, which were both found in Germany (Central...
Article
Full-text available
The European wolf spider name Lycosa accentuata Latreille, 1817, has had a long and convoluted nomenclatural history. The interpretation of the name has baffled arachnologists for more than two centuries. Here we describe the historical development of the evolving interpretations and show that the name is certainly not a senior synonym of Alopecosa...
Article
Full-text available
Plant invasions can have major impacts on ecosystems and influence global species diversity. In Central Europe, Himalayan balsam ( Impatiens glandulifera ) and American goldenrods ( Solidago canadensis and S. gigantea ) are important invaders often establishing dense and homogeneous stands, especially in urban and other disturbed habitats. We inves...
Article
Full-text available
The natural and life history of the family Viridasiidae is largely unexplored. Laboratory observations on specimens of a species belonging to the genus Viridasius Simon, 1889 have shown that it constructs hanging, silken retreatsfor molting and hiding. These retreats are camouflaged with soil, sand, or debris, similar to the already known egg sac o...

The conversion of semi-natural habitats and land-use intensification are major threats to terrestrial biodiversity. While the decline in insects and particularly wild bees seems to be ongoing in agricultural landscapes, there is evidence for the persistence of rare species, and even generalists performing better, in urban areas. This seems surprisi...

Article
Full-text available
A surprisingly large number of European spider species have never been reliably rediscovered since their first description many decades ago. Most of these are probably synonymous with other species or unidentifiable, due to insufficient descriptions or missing type material. In this second part of a series on this topic, we discuss about 100 of the...

Full-text available
Cheiracanthium rupestre Herman, 1879, and Xysticus albomaculatus Kulczyński, 1891, both originally described from Hungary, are among the most rarely reported species of their genera in Europe. Here we report that both of these species have very close relationships to similarly uncommon species originally described from France at about the same time...
Article
Full-text available
The five European species of the genus Larinioides are among the most conspicuous spiders of the area, and some of them can be the dominant orb weavers of their habitat. Three of the species were described by Clerck (1757), yet their nomenclatural history since then has been marred by considerable confusion. Only in the last 40 years has the nomenc...
