Spiders (Araneae) of Stony Debris in North Bohemia
Arachnol. Mitt. 12:46-56 Basel, Dezember 1996 Spiders (Araneae) of stony debris in North Bohemia o v v Vlastimil RUZICKA & Jaromfr HAJER Abstract: The arachnofauna was studied at five stony debris sites in northern Bohemia. In Central Europe, the northern and montane species inhabiting cold places live not only on mountain tops and peat bogs but also on the lower edges of boulder debris, where air streaming through the system of inner compartments gives rise to an exceedingly cold microclimate. At such cold sites, spiders can live either on bare stones (Bathyphantes simillimus, Wubanoides ura/ensis), or in the rich layers of moss and lichen (Dip/oeentria bidentata). Kratoehviliella bieapitata exhibits a diplostenoecious occurrence in stony debris and on tree bark. Latithorax faustus and Theonoe minutissima display diplostenoecious occurrence in stony debris and on peat bogs. The occurrence of the species Seotina eelans in the Czech Republic was documented for the first time. Key words: Spiders, stony debris, microclimate, geographic distribution. INTRODUCTION Stony debris constitute, in Central Europe, island ecosystems which have remained virtually intact over the entire Holocene. Due to the unfeasibility of utilization, stony debris areas are among the few ecosystems that have only minimally been affected by man. In bulky accumulations, air can flow through the system of internal spaces. In this way, cold air can accumulate in the lower part of the tal us, so that ice can form and persist there until late spring. This phenomenon, well known from the Alp region (FURRER 1966), occurs widely in North Bohemia (KUBAT 1971). Owing to the specific substrate and microclimate, stony debris areas are inhabited by specific plant (SADLO & KOLBEK 1994) and animal communities, contributing thus o v v significantly to the biodiversity of the landscape (RUZICKA 1993a). -

BULLETIN OF THE UNIVERSITY OF UTAH Volume 23 December, 1932 No. 2 North American Spiders of the Genera Cybaeus and Cybaeina BY RALPH V. CHAMBERLIN and WILTON IVIE BIOLOGICAL SERIES, Vol. II, No. / - PUBLISHED BY THE UNIVERSITY OF UTAH SALT LAKE CITY THE UNIVERSITY PRESS UNIVERSITY OF UTAH SALT LAKE CITY A Review of the North American Spider of the Genera Cybaeus and Cybaeina By R a l p h V. C h a m b e r l i n a n d W i l t o n I v i e The frequency with which members of the Agelenid genus Cybaeus appeared in collections made by the authors in the mountainous and timbered sections of the Pacific coast region and the representations therein of various apparently undescribed species led to the preparation of this review of the known North American forms. One species hereto fore placed in Cybaeus is made the type of a new genus Cybaeina. Most of our species occur in the western states; and it is probable that fur ther collecting in this region will bring to light a considerable number of additional forms. The drawings accompanying the paper were made from specimens direct excepting in a few cases where material was not available. In these cases the drawings were copied from the figures published by the authors of the species concerned, as indicated hereafter in each such case, but these drawings were somewhat revised to conform with the general scheme of the other figures in order to facilitate comparison. -

Epigean Spider Diversity in the Classical Karst
HACQUETIA 8/1 • 2009, 67–78 DOI: 10.2478/v10028-009-0005-z EpIgean spIdEr dIvErsIty In thE clAssIcAl KArst Matjaž GREGORIČ*1 & Matjaž KUNTNER1 Abstract The classical Karst (Kras in Slovenian) is a limestone karst plateau of south-western Slovenia and north- eastern Italy surrounded by flysch or alluvial areas. We explored surface spider species richness in the Karst by conducting a season-long quantitative inventory of the epigean fauna. By examining three localities, each with three succession-stage sites (grassland, overgrowth, forest) we tested for differences in alpha and beta diversity among different successions based on species incidence data. A total of 90 ethylene glycol pitfall traps (10 traps per each of nine sites) operated between 24. V. 2005 and 20. VII. 2006. We recorded a total of 3681 adult spiders belonging to 136 species, 82 genera and 30 families. Of these 28 species are new records for Slovenia. The observed species richness and total adult spider abundances were highest in the spring and early summer, and among succession stages they were highest in grassland (95 species; 1563 individuals), fol- lowed by overgrowth (81 species; 1047 individuals) and forest (64 species; 1071 individuals). By comparing our results with previous pitfall samplings in the Dinaric karst, we conclude that the sampling effort needed for a meaningful estimation of epigean spider diversity was barely sufficient in our study when all data were combined, but completely inadequate in previous samplings. In our study the total species richness was esti- mated by nonparametric statistics to lie at 181, thus 25 % richer than observed. -
Policy Highlights Marine Protected Areas Economics, Management and Effective Policy Mixes
Marine Protected Areas Economics, Management and Effective Policy Mixes Policy HIGHLIGHTS Marine Protected Areas Economics, Management and Effective Policy Mixes Progress in expanding the coverage of marine protected areas is underway. With a push from the Sustainable Development Goals their global coverage is expected to increase even further. But their effectiveness is uneven. It is one thing to draw a line on a map – it is another to effectively design, site, monitor and enforce them. We are starting to understand what works and what doesn’t. Adaptive management and improvements over time will be essential if marine conservation and sustainable use objectives are to be met. Simon Upton – OECD Environment Director POLICY HI G HLI G H T Pressures on marine ecosystems from human activities are already severe and the often S competing demands for marine space and resources are projected to rise. Costs of poor ocean management practices include environmental and social costs that are often not factored into decision-making processes. This undermines the resilience of the ecosystems upon which we depend, for food, for income, but also other less visible life-support functions such as coastal protection, habitat provisioning and carbon sequestration. Marine protected areas are one of the policy instruments available to help ensure the conservation and sustainable use of our vast yet vulnerable ecosystems. While progress is being made towards increasing the global coverage of marine protected areas, significantly greater efforts are needed to ensure these are also being located in areas that are under threat and can therefore yield greatest environmental benefits, and that they are effectively managed. -

Biodiversity Data Journal 1: e977. doi: 10.3897/BDJ.1.e977 Abstract A total of 294 species from 31 families have been found in Galichitsa Mt. Of them, 85 species are new to the mountain, while 20 are also new to the fauna of FYR of Macedonia. According to their current distribution the established species can be assigned to 17 zoogeographical categories, grouped into 5 complexes (Cosmopolitan, Holarctic, European, Mediterranean, Endemics of Balkans). Dominant are Holarctic species (66.0%) followed by European (16.5%) and Mediterranean (9.3%). The endemics (6.2%) and Southeast European species (1.7%) emphasize the local character of this fauna, but its low percentage suggests an important process of colonization.

Evaluator: Tim Mark Ziesche, Landeskompetenzzentrum Eberswalde Published online at the Institutional Repository of the University of Potsdam: URL http://opus.kobv.de/ubp/volltexte/2011/5558/ URN urn:nbn:de:kobv:517-opus-55588 http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-55588 Abstract The heterogeneity in species assemblages of epigeal spiders was studied in a natural forest and in a managed forest. Additionally the effects of small-scale microhabitat heterogeneity of managed and unmanaged forests were determined by analysing the spider assemblages of three different microhabitat structures (i. vegetation, ii. dead wood. iii. litter cover). The spider were collected in a block design by pitfall traps (n=72) in a 4-week interval. To reveal key environmental factors affecting the spider distribution abiotic and biotic habitat parameters (e.g. vegetation parameters, climate parameters, soil moisture) were assessed around each pitfall trap. A TWINSPAN analyses separated pitfall traps from the natural forest from traps of the managed forest. A subsequent discriminant analyses revealed that the temperature, the visible sky, the plant diversity and the mean diameter at breast height as key discriminant factors between the microhabitat groupings designated by The TWINSPAN analyses.
