“…The habitat of G. microps is described as characteristic of willow thickets, under stones, in moss, meadows, and moors (Platnick and Dondale 1992) and previous authors have noted its affinities for wet environments with thick moss/lichen layer, such as peatlands, arctic-alpine tundra, and many white spruce stands (Aitchison-Benell 1994; Koponen 1994; Pinzon et al 2012). Another lycosid, Pardosa hyperborea (Thorell) (Araneae: Lycosidae) (Supplementary Appendix 1), although uncommon, was collected only from the tree bog in our study and has been previously associated with coniferous forest, peatlands, bog, tundra environment, and harvested conifer forest (Dondale and Redner 1990; Aitchison-Benell 1994; Nordstrom and Buckle 2002; Pinzon et al 2011, 2012). Koponen (1994) noted that both G. microps and P. hyperborea are northern species found mainly in bogs in more southern localities, a phenomena also characterising other species inhabiting peat bogs (Spitzer and Danks 2006).…”

“…Pardosa mackenziana (Keyserling) (Araneae: Lycosidae), significantly indicated the low bush cranberry aspen-dominated ecosite (Table 2). This species is among the commonest spiders of the Canadian boreal forest (Pearce et al 2004; Work et al 2004; Pinzon et al 2011, 2012) and may be found in many different habitats such as salt marshes, beaches, and deciduous forest (Lowrie 1973; Dondale and Redner 1990; Buddle et al 2000; Nordstrom and Buckle 2002). Pardosa mackenziana could be considered as generalist but in our study and the studies by Work et al (2004) and Pinzon et al (2012) conducted at the same site in northwestern Alberta, this species appears to be more common in deciduous forest than in coniferous forest and bogs.…”

Effect of habitat type and pitfall trap installation on captures of epigaeic arthropod assemblages in the boreal forest

et al. 2013

It is unrealistic to achieve high-resolution biodiversity inventories required to support local conservation strategies over large areas; however, benchmark associations between arthropods and ecosystem classification can support landscape scale biomonitoring. We investigated habitat associations of ground-dwelling spiders (Araneae), staphylinid beetles (Coleoptera: Staphylinidae), and carabid beetles (Coleoptera: Carabidae) in three forest ecosystems in northwestern Alberta, Canada and also studied the effect of variation in depth of pitfall trap installation on catch. Composition and diversity of all three taxa were correlated with the ecosystem classification map, and 20 species were strong indicators of particular habitats. The black spruce (Picea mariana (Miller) Britton, Sterns, and Poggenburg; Pinaceae) bog supported fewer species and individuals of beetles but this trend was not observed for spiders because of natural history traits associated with their performance in this environment. Pitfall trapping biases were constant among habitats enabling proper comparison of ground-dwelling invertebrate assemblages. Three species of beetles (Agonum retractum LeConte (Coleoptera: Carabidae), Pterostichus brevicornis (Kirby) (Coleoptera: Carabidae), and Quedius velox Smetana (Coleoptera: Staphylinidae)) were disproportionally active beneath the soil surface, as catches were greater in pitfall traps with the lip situated 15-25 cm below the soil surface. Thus, even highly standardised trap placement will influence the concept of biodiversity achieved through pitfall trapping, because some target organisms are disproportionately active in subterranean zones.Résumé-La connaissance des associations entre les arthropodes épigés et la classification des écosystèmes forestiers peut procurer un inventaire pouvant supporter les stratégies de conservation de la biodiversité sur de grandes superficies. Nous avons examiné les associations des espèces d'araignées (Araneae), de staphylins (Coleoptera : Staphylinidae) et de carabes (Coleoptera: Carabidae) avec trois habitats forestiers du nord-ouest de l'Alberta, Canada. Nous avons aussi étudié l'effet de la variation de profondeur d'installation des pièges fosses sur les captures. La composition et diversité des trois taxa était étroitement reliée au système de classification des écosystèmes forestiers et 20 espèces furent identifiées comme étant fortement indicatrices d'un certain habitat. Le peuplement d'épinette noire (Picea mariana (Miller) Britton, Sterns, and Poggenburg; Pinaceae) supportait moins d'espèces et d'individus de coléoptères mais cette tendance ne fut pas observée pour les araignées parce que certains traits fonctionnels leur permettent de performer dans cet environnement adverse. Les biais des pièges fosses étaient constants entre types forestiers permettant une comparaison juste des assemblages d'invertébrés épigés. Trois coléoptères (Agonum retractum LeConte (Coleoptera: Carabidae), Pterostichus brevicornis (Kirby) (Coleoptera: Carabidae), and Quedius velox ...

Eight species attributed to Tmeticus are reviewed; five are redescribed and illustrated: Tmeticus affinis (Blackwall, 1885), Tmeticus bipunctis (Bösenberg & Strand, 1906), Tmeticus nigriceps Kulczyński, 1916, Tmeticus ornatus (Emerton, 1914) and Tmeticus tolli Kulczyński, 1908. The new genus, Paratmeticus gen. n. is erected for Tmeticus bipunctis, and a new combination is established: Paratmeticus bipunctis (Bösenberg & Strand, 1906), comb. n. Three species names: Gongylidium vile Kulczyński, 1885, syn. n., Tmeticus difficilis Kulczyński, 1926, syn. n. and Tmeticus dubius Kulczyński, 1926, syn. n., are synonymized with Tmeticus tolli Kulczyński, 1908. Although Gongylidium vile has date priority over Tmeticus tolli it is synonymized because of the lack of usage. Three species from Japan attributed to Tmeticus: Tmeticus neserigonoides Saito & Ono, 2001, Tmeticus nigerrimus Saito & Ono, 2001 and Tmeticus vulcanicus Saito & Ono, 2001 are not related to Tmeticus affinis, the type species of the genus, and their affinities remain unclear. The male of Tmeticus nigriceps is described for the first time.
