Spiders (Araneae) of Churchill, Manitoba: DNA Barcodes And
Blagoev et al. BMC Ecology 2013, 13:44 http://www.biomedcentral.com/1472-6785/13/44 RESEARCH ARTICLE Open Access Spiders (Araneae) of Churchill, Manitoba: DNA barcodes and morphology reveal high species diversity and new Canadian records Gergin A Blagoev1*, Nadya I Nikolova1, Crystal N Sobel1, Paul DN Hebert1,2 and Sarah J Adamowicz1,2 Abstract Background: Arctic ecosystems, especially those near transition zones, are expected to be strongly impacted by climate change. Because it is positioned on the ecotone between tundra and boreal forest, the Churchill area is a strategic locality for the analysis of shifts in faunal composition. This fact has motivated the effort to develop a comprehensive biodiversity inventory for the Churchill region by coupling DNA barcoding with morphological studies. The present study represents one element of this effort; it focuses on analysis of the spider fauna at Churchill. Results: 198 species were detected among 2704 spiders analyzed, tripling the count for the Churchill region. Estimates of overall diversity suggest that another 10–20 species await detection. Most species displayed little intraspecific sequence variation (maximum <1%) in the barcode region of the cytochrome c oxidase subunit I (COI) gene, but four species showed considerably higher values (maximum = 4.1-6.2%), suggesting cryptic species. All recognized species possessed a distinct haplotype array at COI with nearest-neighbour interspecific distances averaging 8.57%. Three species new to Canada were detected: Robertus lyrifer (Theridiidae), Baryphyma trifrons (Linyphiidae), and Satilatlas monticola (Linyphiidae). The first two species may represent human-mediated introductions linked to the port in Churchill, but the other species represents a range extension from the USA. -

Hygropetric and Litter-Inhabiting Spiders (Araneae) from the Abruzzo Apennines (Central Italy)
Arachnol. Mitt. 37: 15-26 Nürnberg, Juli 2009 Hygropetric and litter-inhabiting spiders (Araneae) from the Abruzzo Apennines (Central Italy) Marco Isaia, Giuseppe Osella & Giovanna Pannunzio Abstract: We present the results of a study of spider material extracted by means of Berlese apparatus from wet mosses and by litter sieving in broadleaf woods within several natural reserves of the Abruzzo region (Central Italy). The main aim of the work is to contribute to the knowledge of the spider fauna of the Apen- nines; currently one of the lesser known in Italy. In total, 520 spiders, belonging to 49 species and 14 families were collected. The most abundant and diverse family was Linyphiidae, with 278 individuals belonging to 22 species. Altogether we provide 28 new records for the Abruzzo region, including two species of Theridiidae, twenty of Linyphiidae, four of Hahniidae and two of Thomisidae. We also present additional unpublished records of several rare, litter-inhabiting species collected by litter sieving in the same area. Data on habitat preferences and details on the Italian distribution of the rarest species are presented. Key words: Berlese apparatus, Dysderidae, Linyphiidae, litter sieving, National Park of Gran Sasso, National Park of Monti della Laga, regional fauna Hygropetric habitats become established on rocky published records of several rare, litter-inhabiting or soil surfaces, with thin water films moving down species collected by litter sieving in the same area, in a mostly laminar flow. This habitat is colonised including details on their Italian distribution and mainly by bryophytes (mosses and peat-mosses) habitat preference. and often harbours unique assemblages of arthro- pods, characterised by endemic or rare species. -

(2009),24(1-3): 2 In memoriam JEAN-PIERRE MAELFAIT Kortrijk 01/06/1951 Gent 06/02/2009 Jean-Pierre Maelfait is ons ontvallen op 6 februari van dit jaar. We brengen hulde aan een man die veel gegeven heeft voor de arachnologie in het algemeen en meer specifiek voor onze vereniging. Jean-Pierre is altijd een belangrijke pion geweest in het bestaan van ARABEL. Hij was medestichter van de “Werkgroep ARABEL” in 1976 en op zijn aanraden werd gestart met het publiceren van de “Nieuwsbrief” in 1986, het jaar waarin ook ARABEL een officiële vzw werd. Hij is eindredacteur van de “Nieuwsbrief” geweest van 1990 tot en met 2002. Sinds het ontstaan van onze vereniging is Jean-Pierre achtereenvolgens penningmeester geweest van 1986 tot en met 1989, ondervoorzitter van 1990 tot en met 1995 om uiteindelijk voorzitter te worden van 1996 tot en met 1999. Pas in 2003 gaf hij zijn fakkel als bestuurslid over aan de “jeugd”. Dit afscheid is des te erger omdat Jean- Pierre er na 6 jaar afwezigheid terug een lap ging op geven, door opnieuw bestuurslid te worden in 2009 en aldus verkozen werd als Secretaris. Alle artikels in dit nummer opgenomen worden naar hem opgedragen. Jean-Pierre Maelfait nous a quitté le 6 février de cette année. Nous rendons hommage à un homme qui a beaucoup donné dans sa vie pour l’arachnologie en général et plus particulièrement pour Arabel. Jean-Pierre a toujours été un pion important dans la vie de notre Société. -

ZooKeys 841: 39–59. https:// doi.org/10.3897/zookeys.841.33271 Abstract The scarce and biased knowledge about the diversity and distribution of Araneae species in the Iberian Peninsula is accentuated in poorly known habitats such as the Mesovoid Shallow Substratum (MSS). The aim of this study was to characterize the spiders inventory of the colluvial MSS of the Sierra de Guadar- rama National Park, and to assess the importance of this habitat for the conservation of the taxon. Thirty-three localities were selected across the high peaks of the Guadarrama mountain range and they were sampled for a year using subterranean traps specially designed to capture arthropods in the MSS. -
Spiders (Araneae) of the Abandoned Pasture Near the Village of Malé Kršteňany (Western Slovakia)

It is the southernmost edge of the Strážovské vrchy Mountains (Mts) (48°55ʹ46ʹʹN; 18°26ʹ05ʹʹE), separated from the central massif by the river ow Nitrica. is area is considerably inuenced by human activity: In the past, it had massive deforestation and agricultural use (mainly as pasture), recently, it is dominated by mining activities (several quarries). e whole area is out of the territo- rial protection, with the exception of the little Nature reserve Veľký vrch, surrounded by two quarries, and the le one is more or less abandoned. In the past, this area was used mainly for grazing, but this is currently very limited. Our research site is an aban- doned pasture; therefore, ecological succession is carried out intensively here. Forgot- ten aer-utility areas (abandoned quarries, pastures, industrial sites) are usually con- sidered to be ‘sterile’ and unattractive for zoological research, but this may not always correspond to reality. Even in our research site, we have carried out several rare and surprising ndings. We would like to present the results of our research in this paper. It is sad, but a large amount of abandoned pastures is scattered throughout Slova- kia. -

A new genus and species of spider (Araneae, Linyphiidae, Erigoninae) from a tropical montane cloud forest of Mexico is described from both male and female specimens, Xim trenzado gen. et sp. nov. A phylogenetic parsimony analysis situates Xim gen. nov. as a distinct genus among the distal Erigoninae. Xim gen. nov. is sister to a clade including Ceratinopsis, Tutaibo and Sphecozone, but differs from those genera by having a high cymbium, large paracymbium, short straight embolus, male cheliceral stridulatory striae widely and evenly spaced, both sexes with a post-ocular lobe, male with two series of prolateral macrosetae on femur I, and the female by having strongly oblong, u-shaped spermathecae. -
The Effect of Native Forest Dynamics Upon the Arrangements of Species in Oak Forests-Analysis of Heterogeneity Effects at the Example of Epigeal Arthropods

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.
