“…Nevertheless, the investigation on small-scale spider distribution enhances the understanding of species requirements to habitat factors since the ecology of several spider species in forests is still not well understood. Moreover, our results on spiders are likely to assume that the composition of further functional guilds and indicator taxa may show correlations to small-scale environmental conditions of a forest stand (e.g., Taylor and Doran, 2001;Grand and Mello, 2004;Buddle et al, 2006;Pihlaja et al, 2006) and react with community alterations on human-induced habitat changes (see Charnley et al, 2007;Pohl et al, 2007).…”

“…However, as we included only near‐pristine forested catchments, it may be that our catchment variables simply showed too little variability to overwhelm the impact of local environmental variables in controlling macroinvertebrate community structure. In terrestrial ecosystems, strong relationships between community structure and landscape characteristics have been documented in a number of studies (Grand and Mello 2004, Schweiger et al 2006). For example, after correcting for regional effects, the species composition and functional guilds of terrestrial arthropod communities showed stronger responses to landscape variables than to local environmental variables across anthropogenically altered landscapes (Schweiger et al 2006).…”

We examined the community-environment relationships of lotic macroinvertebrates in near-pristine headwater streams, and the correlation between patterns in taxonomic and functional structure at two regional extents. The across-ecoregion scale comprised five ecoregions spanning all of Finland, while the within-ecoregion scale comprised of north boreal and middle boreal ecoregions. We expected that taxonomic structure should exhibit stronger relationships than functional structure to spatial gradients, while the reverse should be true for local environmental factors. We found some support for this notion, because spatial variables were marginally more important for taxonomic than functional structure. Furthermore, within the two ecoregions, local environmental variables were slightly more important for functional than taxonomic structure. Geographical location (i.e. spatial variables) was more influential at the across-ecoregions extent than within the two ecoregions. Largely the same local environmental variables accounted for variation in both taxonomic and functional structure, including water pH, nutrients, colour, and stream size. Similar responses to local environmental features likely contributed to the significant correlation between patterns in taxonomic and functional structure. It has been suggested that functional traits may be rather insensitive to natural variation, yet our functional categorization showed distinct variation along local environmental, catchment, and spatial gradients across nearpristine streams. Thus, natural ecological filters should be accounted for prior to the examination of the effects of anthropogenic filters on stream macroinvertebrate community composition.

“…We assess the moths' response to two contrasting regimes, mowing and abandonment, within a middle-sized fenland reserve. Unlike studies restricted to Macrolepidoptera, or macro-moths (e.g., Woiwod & Hanski 1992;Grand & Mello 2004;Littlewood 2008;Mutshinda et al 2008;Merckx et al 2009a, b), we also included Microlepidoptera (micro-moths), which are more difficult for handling and identification and hence rarely considered in ecology studies (but see Fuentes-Montemayor et al 2011;Summerville et al 2001). We expected that due to small body sizes, Microlepidoptera might contain a higher number of specialised sedentary species, and should be more sensitive to impacts of site management (e.g., Vávra et al 1996;Spitzer et al 1999;Šumpich 2006;Summerville et al 2007).…”

Although reserves of temperate seminatural grassland require management interventions to prevent succesional change, each intervention affects the populations of sensitive organisms, including insects. Therefore, it appears as a wise bet-hedging strategy to manage reserves in diverse and patchy manners. Using portable light traps, we surveyed the effects of two contrasting management options, mowing and temporary abandonment, applied in a humid grassland reserve in a submountain area of the Czech Republic. Besides of Macrolepidoptera, we also surveyed Microlepidoptera, small moths rarely considered in community studies. Numbers of individiuals and species were similar in the two treatments, but ordionation analyses showed that catches originating from these two treatments differed in species composition, management alone explaining ca 30 per cent of variation both for all moths and if split to Marcolepidoptera and Microlepidoptera. Whereas a majority of macrolepidopteran humid grassland specialists preferred unmown sections or displayed no association with management, microlepidopteran humid grassland specialists contained equal representation of species inclining towards mown and unmown sections. We thus revealed that even mown section may host valuable species; an observation which would not have been detected had we considered Macrolepidoptera only. Our results highlight the necessity of diversified management, including temporary abandonment, to conserve the biodiversity of grassland reserves and grasslands in general.
