Zoologia 34:e19987īogyó D, Magura T, Simon E, Tóthmérész B (2015) Millipede (Diplopoda) assemblages alter drastically by urbanization. Using indicator values, we identified Coelotes atropos, Walckenaeria corniculans, Walckenaeria cucullata, and Pachygnatha listeri as species linked to the rural and suburban habitats Trochosa terricola, Saaristoa abnormis, Robertus lividus as characteristic of the rural habitat and Gongylidium rufipes and Diplocephalus latifrons as urban habitat specialists.Īlaruikka DM, Kotze DJ, Matveinen K, Niemelä J (2002) Carabid and spider assemblages along an urban to rural gradient in southern Finland. Neither the presence of generalists nor light-preferring species increased under more urbanised conditions, but web builders and hygrophilous species were more species-rich in the rural habitat than elsewhere. The number of forest specialist species also decreased along the urbanisation gradient. We found support for Gray’s Increasing Disturbance Hypothesis: the species richness trap −1 was significantly higher in the rural habitat than in any other one, and decreased from the rural forest to forest fragments dominated by non-native trees in the urban park. Using pitfall traps set in forested habitat patches, we collected a total of 3075 adult spiders of 80 species the habitats under different degrees of urbanisation had 45–47 species. We recommend the use of ecoclimatic regions as a framework for conservation of biodiversity in Northern Canada and spiders as useful bioindicators which can help us understand the effects of climate change across ecoclimatic regions of northern Canada.We studied the effects on spiders of a three-step rural-urban urbanisation gradient near a Danish town embedded in a historically forested landscape. At local scales, diversity was non-randomly distributed, and possibly limited by biotic interactions. Longitudinal patterns of spider diversity across Canada may be explained by post-glacial dispersal. Spider diversity was structured at the regional scale across ecoclimatic regions but not with latitude. Over 23, 000 adult spiders, representing 306 species in 14 families, were collected in Northern Canada, with 107 species (35% of the total species collected) representing new Territorial or Provincial records. Variation of diversity was partitioned in relation to multiple environmental and spatial drivers of diversity patterns. Spatial patterns of species richness and composition of Arctic spiders were assessed in 12 sites located in Arctic, Subarctic, and North-Boreal regions, across 30 degrees of latitude and 80 degrees of longitude. We investigated which drivers, environmental or spatial, influence the patterns observed. We examined how Arctic spider (Araneae) biodiversity is distributed at multiple spatial scales in Northern Canada using a standardized hierarchical sampling design.
