Biodiversity Data Journal 5: e21010. https://doi.org/10.3897/BDJ.5.e21010 Abstract Background During a field course on spider taxonomy and ecology at the University of Helsinki, the authors had the opportunity to sample four plots with a dual objective of both teaching on field methods, spider identification and behaviour and uncovering the spider diversity patterns found in the southern coastal forests of Hankoniemi, Finland. As an ultimate goal, this field course intended to contribute to a global project that intends to uncover spider diversity patterns worldwide. With that purpose, a set of standardised methods and procedures was followed that allow the comparability of obtained data with numerous other projects being conducted across all continents. New information A total of 104 species and 1997 adults was collected. -
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. -

Editing Science: Helping Communicate to Scientists, Policy‐Makers and the Public Editors Canada conference, May 26, Saskatoon Carolyn Brown Science Communication | Publishing Consulting 61 Diversity, species richness, and abundance of spiders (Araneae) in different strata of boreal white spruce stands Jaime Pinzon,1 John R. Spence, David W. Langor Abstract—Spiders (Araneae) were sampled in white spruce (Picea glauca (Moench) Voss (Pinaceae)) dominated stands from the ground and shrub layers, and from several overstorey strata to assess patterns in species composition and diversity (alpha and beta) along the vertical gradient (0–12 m above ground). Overall, 3070 adult spiders in 15 families and 76 species were collected, with the ground layer accounting for the highest species richness (40 species) followed by the mid-overstorey (36 spp.) and the shrub layers (33 species). Vertical stratification was apparent in the samples: richness clearly decreased with height, and species turnover between the ground, shrub, and mid-overstorey levels was evident, suggesting that species composition in each layer was highly distinctive. Within the mid-overstorey stratification was less obvious but both species richness and spider abundance were predicted significantly by height from the ground and branch size. Given the role of late-seral conifer stands for maintaining old-growth species, understanding diversity patterns across strata provides basic knowledge to support forest management decisions that effectively conserve spider species and assemblages. It is clearly important to include higher canopy layers in considering impacts of forestry on biodiversity in the boreal mixedwood.

“There Would Doubtless Be a Just Feeling of Pride
“There would doubtless be a just feeling of pride and satisfaction in the heart of a naturalist who could say that he had made himself thoroughly acquainted with all the species of a particular group of animals, had learned their most secret habits, and mastered their several relations to the objects, animate and inanimate, which surrounded them. But perhaps a still keener pleasure is enjoyed by one who carries about with him some problem of the kind but partially solved, and who, holding in his hand the clue which shall guide him onwards, sees in each new place that he visits fresh opportunities of discovery.” J.

PREFACE This brochure is a second one in a series of annual additions to the Catalogue of the spiders of the territories of the former Soviet Union. The basic structure of the main catalogue has not been changed in the present addition (for details, see the Methodology chapter). The checklist includes only species with revised distribution data (giv- en bold). Other novations, like generic affiliation of certain species (especially in the former Lepthyphantes), new synonymy, are to be checked completely in the revised edition of the main catalogue. I am deeply obliged to my colleagues Drs. Yu.M. Marusik (Ma- gadan), A.V. Tanasevitch (Moscow), D.V. Logunov (Novosibirsk), S.L. Esyunin (Perm), Mr. E.M. Zhukovets (Minsk), Mr. A.V. Gromov (Alma-Ata), and to numerous other persons for supplying me with all necessary publications. Several reviews of my catalogue printed during the last year were also taken into consideration. 3 METHODOLOGY Each spider species included in the checklist is supplied with an attribution both to main physiographical areas and to post-Soviet republics. The physiographical areas and republics are coded by Rus- sian letters and abbreviations, respectively. The sequence of referenc- es is as follows: Physiographical areas (see also Map 1). À Atlantic-Arctic insular area, Á Fennoscandia (Karelian-Kola area), Â Russian Plain, Ã1 Novaya Zemlya and Vaigach islands, Ã2 Urals, Ä Carpathians, Å1 Crimea, Å2 Caucasus, Æ1 Armenian Upland, Æ2 Kopetdagh Mts, Ç+È mountainous Middle Asia, Ê deserts of Middle Asia, Ë Kazakhstan hills, Ì West Siberia, Í+Î Middle Siberia, Ï mountains of South Siberia, Ð northeastern Siberia, Ñ1 continental Far North-East (without Kamchatka), Ñ2 Kamchatka, Ñ3 northern Kurile Islands, Ñ4 Commander Islands, Ò1 continental Southern Far East (Amur-Maritime area), Ò2 Sakhalin and Moneron islands, Ò3 southern Kurile Islands. -

Recolonisation des mares d’un fen en restauration par les araignées et les dytiques Mémoire André-Philippe Drapeau Picard Maîtrise en biologie végétale Maître ès sciences (M.Sc.) Québec, Canada © André-Philippe Drapeau Picard, 2016 Recolonisation des mares d’un fen en restauration par les araignées et les dytiques Mémoire André-Philippe Drapeau Picard Sous la direction de : Line Rochefort, directrice de recherche Maxim Larrivée, codirecteur de recherche Résumé La technique du transfert muscinal, largement appliquée pour la restauration des tourbières perturbées par l’extraction de la tourbe en Amérique du Nord, vise le retour d’un couvert végétal dominé par des mousses accumulatrices de tourbe. Bien qu’efficace en ce sens, l’approche ne restaure pas l’hétérogénéité des habitats qui supportent la grande biodiversité des tourbières naturelles. Les mares de tourbière sont des habitats auxquels une faune et une flore caractéristiques sont associées et qui contribuent significativement à la biodiversité des tourbières. La création de mares dans les tourbières restaurées devrait y augmenter l’hétérogénéité des habitats et, ainsi, la biodiversité. Dans virtuellement tous les écosystèmes, les arthropodes sont diversifiés et abondants, et ils sont sensibles aux variations environnementales à une échelle fine, ce qui fait d’eux des indicateurs écologiques intéressants. Pour ce projet, 21 mares réparties dans deux classes de profondeur (profondes et peu profondes) et trois classes de végétation (mousses, arbustes et plantes graminoïdes) ont été aménagées lors de la restauration d’une tourbière minérotrophe dans la région du Bas-Saint-Laurent. Les mares de quatre tourbières des environs ont été inventoriées en tant qu’écosystème de référence. -
Arachnida: Araneae) of the Canadian Prairies
75 Chapter 4 Spiders (Arachnida: Araneae) of the Canadian Prairies Héctor Cárcamo Lethbridge Research Centre, Agriculture and Agri-Food Canada, Lethbridge, AB Jaime Pinzón Department of Renewable Resources, Faculty of Agricultural, Life and Environmental Sciences, University of Alberta, Edmonton Robin Leech 10534, 139 St NW, Edmonton AB John Spence Department of Renewable Resources, Faculty of Agricultural, Life and Environmental Sciences, University of Alberta, Edmonton Abstract. Spiders are the seventh most diverse order of arthropods globally and are prominent predators in all prairie habitats. In this chapter, a checklist for the spiders of the Prairie Provinces (767 recorded species and 44 possible species) is presented along with an overview of all 26 families that occur in the region. Eighteen of the species from the region are adventive. Linyphiidae is by far the dominant family, representing 39% of all species in the three provinces. Gnaphosidae and Lycosidae each represent 8% and three other families (Salticidae, Dictynidae, and Theridiidae) each account for 7%. A summary of biodiversity studies conducted in the Prairies Ecozone and from transition ecoregions is also provided. The Mixed Grassland Ecoregion has the most distinctive assemblage; Schizocosa mccooki and Zelotes lasalanus are common only in this ecoregion. Other ecoregions appear to harbour less distinctive assemblages, but most have been poorly studied. Lack of professional opportunities for spider systematists in Canada remains a major barrier to the advancement of the taxonomy and ecology of spiders. Résumé. Les aranéides forment le septième ordre le plus diversifi é d’arthropodes dans le monde; ce sont des prédateurs très présents dans tous les habitats des Prairies. -
Unexpectedly High Among-Habitat Spider (Araneae) Faunal Diversity
219 Unexpectedly high among-habitat spider (Araneae) faunal diversity from the Arctic Long-Term Experimental Research (LTER) field station at Toolik Lake, Alaska, United States of America Derek S. Sikes,1 Michael L. Draney, Brandi Fleshman Abstract—A comparison is made between a three-year structured-sampling study that compared spider faunas of two tundra habitats and a single-year unstructured-sampling study, both within the Arctic Long-Term Experimental Research (LTER) field station at Toolik Lake, Alaska, United States of America. The three-year study documented 51 species and predicted a total of 60 species for the area. Our one season study documented 39 species, of which 24, or 62%, are not shared by the three-year study, raising the total count for the LTER to 75 species. These findings emphasise limitations of species richness estimation methods and help dispel the perception that Arctic tundras are homogeneous and species poor. Re´sume´—Nous comparons une e´tude de trois ans sur les faunes d’araigne´es de deux habitats de toundra base´e sur une e´chantillonnage structure´a` une autre e´tude d’un an base´e sur un e´chantil- lonnage non structure´; les deux e´tudes ont e´te´re´alise´es dans le cadre de l’Arctic LTER (Long Term Experimental Research – recherche expe´rimentale a` long terme) station de recherche au lac Toolik, Alaska, E´ tats-Unis d’Ame´rique.

Identifying Spiders Through DNA Barcodes
481 Identifying spiders through DNA barcodes Rowan D.H. Barrett and Paul D.N. Hebert Abstract: With almost 40 000 species, the spiders provide important model systems for studies of sociality, mating systems, and sexual dimorphism. However, work on this group is regularly constrained by difficulties in species identi- fication. DNA-based identification systems represent a promising approach to resolve this taxonomic impediment, but their efficacy has only been tested in a few groups. In this study, we demonstrate that sequence diversity in a standard segment of the mitochondrial gene coding for cytochrome c oxidase I (COI) is highly effective in discriminating spider species. A COI profile containing 168 spider species and 35 other arachnid species correctly assigned 100% of subse- quently analyzed specimens to the appropriate species. In addition, we found no overlap between mean nucleotide di- vergences at the intra- and inter-specific levels. Our results establish the potential of COI as a rapid and accurate identification tool for biodiversity surveys of spiders. Résumé : Avec presque 40 000 espèces, les araignées constituent un modèle important pour l’étude de la vie sociale, des systèmes d’accouplement et du dimorphisme sexuel. Cependant, la recherche sur ce groupe est souvent restreinte par les problèmes d’identification des espèces. Les systèmes d’identification basés dur l’ADN présentent une solution prometteuse à cette difficulté d’ordre taxonomique, mais leur efficacité n’a été vérifiée que chez quelques groupes. Nous démontrons ici que la diversité des séquences dans un segment type du gène mitochondrial de la cytochrome c oxydase I (COI) peut servir de façon très efficace à la reconnaissance des espèces d’araignées. -

Biodiversity Data Journal 8: e55242. https://doi.org/10.3897/BDJ.8.e55242 Abstract Background Since the late 1980s, long-term monitoring of various components of natural ecosystems under conditions of industrial pollution has been carried out in the Central Urals. In the mid-2000s, similar programmes were started in the Southern Urals. As a part of these monitoring programmes, the data on invertebrates in different types of biotopes, collected with different methods and in a different time intervals, continue to be gathered. Amongst the most well-studied groups of invertebrates are spiders and harvestmen whose communities are a convenient indicator of the environment. The data collected through these monitoring programmes can also be used to study natural local biodiversity. New information The dataset, presented here, includes information from a long-term monitoring programme for Araneae and Opiliones that inhabit grass stands of secondary dry meadows and litter of spruce-fir, aspen-birch and pine-birch forests in the Central and Southern Urals. The dataset (available from the GBIF network at https://www.gbif.org/dataset/e170dbd1- a67f-4514-841c-5296b290ca90) describes the assemblage structure of spiders and © Nesterkov A et al.
