Untangling Taxonomy: a DNA Barcode Reference Library for Canadian Spiders
Molecular Ecology Resources (2016) 16, 325–341 doi: 10.1111/1755-0998.12444 Untangling taxonomy: a DNA barcode reference library for Canadian spiders GERGIN A. BLAGOEV, JEREMY R. DEWAARD, SUJEEVAN RATNASINGHAM, STEPHANIE L. DEWAARD, LIUQIONG LU, JAMES ROBERTSON, ANGELA C. TELFER and PAUL D. N. HEBERT Biodiversity Institute of Ontario, University of Guelph, Guelph, ON, Canada Abstract Approximately 1460 species of spiders have been reported from Canada, 3% of the global fauna. This study provides a DNA barcode reference library for 1018 of these species based upon the analysis of more than 30 000 specimens. The sequence results show a clear barcode gap in most cases with a mean intraspecific divergence of 0.78% vs. a min- imum nearest-neighbour (NN) distance averaging 7.85%. The sequences were assigned to 1359 Barcode index num- bers (BINs) with 1344 of these BINs composed of specimens belonging to a single currently recognized species. There was a perfect correspondence between BIN membership and a known species in 795 cases, while another 197 species were assigned to two or more BINs (556 in total). A few other species (26) were involved in BIN merges or in a combination of merges and splits. There was only a weak relationship between the number of specimens analysed for a species and its BIN count. However, three species were clear outliers with their specimens being placed in 11– 22 BINs. Although all BIN splits need further study to clarify the taxonomic status of the entities involved, DNA bar- codes discriminated 98% of the 1018 species. The present survey conservatively revealed 16 species new to science, 52 species new to Canada and major range extensions for 426 species. -

MAPPING THE VARIATION IN SPIDER BODY COLOURATION FROM AN INSECT PERSPECTIVE Ajuria-Ibarra, H. 1 Tapia-McClung, H. 2 & D. Rao 1 1. INBIOTECA, Universidad Veracruzana, Xalapa, Veracruz, México. 2. Laboratorio Nacional de Informática Avanzada, A.C., Xalapa, Veracruz, México. Colour variation is frequently observed in orb web spiders. Such variation can impact fitness by affecting the way spiders are perceived by relevant observers such as prey (i.e. by resembling flower signals as visual lures) and predators (i.e. by disrupting search image formation). Verrucosa arenata is an orb-weaving spider that presents colour variation in a conspicuous triangular pattern on the dorsal part of the abdomen. This pattern has predominantly white or yellow colouration, but also reflects light in the UV part of the spectrum. We quantified colour variation in V. arenata from images obtained using a full spectrum digital camera. We obtained cone catch quanta and calculated chromatic and achromatic contrasts for the visual systems of Drosophila melanogaster and Apis mellifera. Cluster analyses of the colours of the triangular patch resulted in the formation of six and three statistically different groups in the colour space of D. melanogaster and A. mellifera, respectively. Thus, no continuous colour variation was found. -

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. -
A Protocol for Online Documentation of Spider Biodiversity Inventories Applied to a Mexican Tropical Wet Forest (Araneae, Araneomorphae)

C. P. 04510. Del. Coyoacán, Ciudad de México, México. E-mail: [email protected] 2Corresponding author Abstract Spider community inventories have relatively well-established standardized collecting protocols. Such protocols set rules for the orderly acquisition of samples to estimate community parameters and to establish comparisons between areas. These methods have been tested worldwide, providing useful data for inventory planning and optimal sampling allocation efforts. The taxonomic counterpart of biodiversity inventories has received considerably less attention. Species lists and their relative abundances are the only link between the community parameters resulting from a biotic inventory and the biology of the species that live there. However, this connection is lost or speculative at best for species only partially identified (e. g., to genus but not to species). This link is particularly important for diverse tropical regions were many taxa are undescribed or little known such as spiders. One approach to this problem has been the development of biodiversity inventory websites that document the morphology of the species with digital images organized as standard views. -

(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. -
