“…Similar responses to ours have been demonstrated for other taxa. Species richness and abundance of ground-dwelling spiders is significantly higher and spider species composition is different on the surface of DWM compared to the forest floor (Buddle 2001; Varady-Szabo and Buddle 2006). The responses of these two taxa, spiders and oribatid mites, are remarkably similar; rarefied species richness is highest on DWM, and species composition on wood differs from that adjacent to DWM and on the forest floor.…”

The removal of timber during harvesting substantially reduces important invertebrate habitat, most noticeably microhabitats associated with fallen trees. Oribatid mite diversity in downed woody material (DWM) using species-level data has not been well studied. We investigated the influence of decaying logs on the spatial distribution of oribatid mites on the forest floor at the sylviculture et aménagement forestiers écosysté-mique (SAFE) research station in the Abitibi region in NW Québec. In June 2006, six aspen logs were selected for study, and samples were taken at three distances for each log: directly on top of the log (ON), directly beside the log (ADJ) and at least one metre away from the log and any other fallen wood (AWAY). Samples ON logs consisted of a litter layer sample, an upper wood sample and an inner wood sample. Samples at the ADJ and AWAY distances consisted of litter samples and soil cores. The highest species richness was collected ON logs, and logs harboured a distinct oribatid species composition compared to nearby forest floor. There were species-specific changes in abundance with increasing distance away from DWM, which indicates an influence of DWM in structuring oribatid assemblages on the forest floor. Additionally, each layer (litter, wood and soil) exhibited a unique species composition and hosted a different diversity of oribatid mites. This study further highlights the importance of DWM to forest biodiversity by creating habitat for unique assemblages of oribatid mites.

“…Birds may actively use wood barriers for shelter, roosting, perching and even as feeding points. Even without fruiting plants, coarse woody debris can be a source of macro-arthropods in winter (Jabin et al 2004, Varady-Szabo & Buddle 2006, and the majority of the frugivorous species we found also have an insectivore component in their diet (Snow & Perrins 1998). Consequently, the higher use of the barriers by frugivorous-insectivorous birds could be the cause of the higher seed dispersion rate in this microhabitat.…”

Can salvage logging affect seed dispersal by birds into burned forests?

The recovery of vegetation in Mediterranean ecosystems after wildfire is mostly a result of direct regeneration, since the same species existing before the fire regenerate on-site by seeding or resprouting. However, the possibility of plant colonization by dispersal of seeds from unburned areas remains poorly studied. We addressed the role of the frugivorous, bird-dependent seed dispersal (seed rain) of fleshy-fruited plants in a burned and managed forest in the second winter after a fire, before on-site fruit production had begun. We also assessed the effect on seed rain of different microhabitats resulting from salvage logging (erosion barriers, standing snags, open areas), as well as the microhabitats of unlogged patches and an unburned control forest, taking account of the importance of perches as seed rain sites. We found considerable seed rain by birds in the burned area. Seeds, mostly from Olive trees Olea europaea and Evergreen pistaches Pistacia lentiscus, belonged to plants fruiting only in surrounding unburned areas. Seed rain was heterogeneous, and depended on microhabitat, with the highest seed density in the unburned control forest but closely followed by the wood piles of erosion barriers. In contrast, very low densities were found under perches of standing snags. Furthermore, frugivorous bird richness seemed to be higher in the erosion barriers than elsewhere. Our results highlight the importance of this specific post-fire management in bird-dependent seed rain and also may suggest a consequent heterogeneous distribution of fleshy-fruited plants in burned and managed areas. However, there needs to be more study of the establishment success of dispersed seeds before an accurate assessment can be made of the role of bird-mediated seed dispersal in post-fire regeneration.

“…However, there is little information about CWD's impact on the near environment within transect distance. The majority of this research is carried out on logs (Jabin et al, 2004;Kappes et al, 2006;Varady-Szabo and Buddle, 2006). It should be emphasized that applied distances from CWD varied in range.…”

Mesostigmatid mites are one of the natural elements of soil fauna, but they are also found in decomposing wood. Many studies have focused on mites in decayed logs; however, information about the mite communities in decayed stumps and additionally in the adjacent litter is scarce. The primary objective of this study was to analyze how the mite fauna differs between Scots pine (Pinus sylvestris L.) and sessile oak [Quercus petraea (Matt.) Liebl.] stumps, as well as to discover how much the stumps affect the soil mite community in temperate forests. This study was conducted in two managed forests (pine versus oak) in five microhabitats [clear-cut stumps, ecotone, and litter at three distances (0.5, 1.0, and 1.5 m)]. The forests were 98 years old, growing in brownish, rusty soil and were located in the Murowana Goślina Forest Experimental Station (Poznań, Central Poland). Our study revealed that the mean number of species, mean abundance, and evenness differed between the pine and oak forests. Additionally, the study indicated that Scots pine and sessile oak clear-cut stumps as well as the adjacent litter (up to 1.5 m away) were inhabited by the same abundant mite species. Moreover, unique species such as Oplitis minutissima and Pergamasus mediocris were restricted in distribution to ecotone in the Scots pine forest.
