“…The same pattern is observed in this study with the only characteristic plant species of restored (either by managed realignment or accidentally, the pioneer and invasive Spartina anglica) sites different from typical, target, species from natural salt marshes (mainly Atriplex portulacoides). The great long-distance dispersal abilities of spiders likely explain the early colonization of realigned sites by halophilic species, with a possible fast colonization of most sites from the regional species pool (Pétillon and Garbutt, 2008;Cristofoli et al, 2010). These dispersal capacities are probably higher than those of ground beetles (Varet et al, 2013), group in which incomplete restoration has been shown after dozen of years in littoral habitats (Desender et al, 2007).…”

Studying successional processes and related factors in salt marshes encompasses both fundamental (community structuration) and applied (biodiversity conservation and restoration) issues. Current managed realignment projects and sites where, in the past, large storm events led to breaches in embankments create unique experimental conditions for such challenges by re-instating tidal inundation and salt-marsh development. We conducted a pairmatched approach using natural and recreated (either accidentally or managed) salt marshes and studied changes in invertebrate communities over time during a field experiment (Essex, UK). Trophic guild was assigned to all invertebrates, and detailed analyses conducted on most abundant (amphipods, Orchestia sp., 9666 individuals) and diversified (spiders, 43 species) groups. A total of 27,180 invertebrates (almost all arthropods: 99 % of specimens) was collected in 2005. The conservation equivalency was achieved quickly (which was shown here with spider assemblages), but that did not translate into a complete functional equivalency. Indeed neither the structure of trophic guilds, nor the potential role of marine enrichment and fish nursery, estimated through the population size of amphipods, were achieved by managed realignments. We finally argue that the study of invertebrates brings information complementary to those brought by plants, and underline that functional and conservation equivalency have to be assessed separately.

“…Trait-based approaches were previously applied to spider communities to study landscape fragmentation in apple orchards (Herrmann et al 2010), and heathland restoration (Cristofoli et al 2010). To our knowledge, this approach has not yet been used to study the effects of management strategies (including abandoned orchards) or seasons (i.e.…”

The impact of management strategies in apple orchards on the structural and functional diversity of epigeal spiders

Apple orchards are agro-ecosystems managed with high levels of inputs and especially pesticides. Epigeal spider communities were sampled in three seasons using pitfall traps in 19 apple orchards with four different management strategies (abandoned, under organic, Integrated Pest Management or conventional protection) and thus significantly different pesticide usage. The abundance and diversity of the spider communities was the highest in abandoned orchards. Higher diversity and evenness values were the only difference in spider communities from the organic orchards compared to the other commercial orchards. The analysis of five ecological traits (proportion of aeronauts, type of diet, overwintering stages, body size and maternal care), however, clearly showed differences in the spiders from the organic orchards. The spider species in the other commercial orchards were smaller and have higher dispersal abilities. Seven bioindicator species were identified in abandoned orchards, two species in organic ones (only Lycosidae) and one species in conventional orchards (Linyphiidae).

“…Both carabids (Coleoptera: Carabidae) and spiders (Araneae) have received attention as potential indicator taxa (Niemela et al, 1993;Beaudry et al, 1997;Marc et al, 1999;Larochelle & Lariviere, 2003;Rainio & Niemela, 2003;Pearce & Venier, 2006;Gillette et al, 2008;Cristofoli et al, 2010). Lovei and Sunderland (1996), however, have also suggested that failure to account for the presence of ants (Hymenoptera: Formicidae) in some community studies could result in the formation of incomplete or invalid conclusions.…”

“…Spiders have also received attention regarding their potential use as biological indicators (Marc et al, 1999;Pearce & Venier, 2006;Gillette et al, 2008;Cristofoli et al, 2010). The spider fauna is very species-rich and has high functional diversity.…”

“…Spiders (Araneae) are abundant in many habitats, and because many species potentially overlap with ants in terms of niche characteristics and seasonal activity patterns (Van der Aart & de Wit, 1971;Turnbull, 1973;Holldobler & Wilson, 1990) it has been proposed that ants and some spiders may be competitors and/or mutual predators (Van der Aart & de Wit, 1971;Wise, 1993;Halaj et al, 1997;Heikkinen, 1999;Sanders & Platner, 2007). The potential for interspecific interactions to occur between these groups is important given the attention spiders have received as possible bioindicators of environmental conditions (Marc et al, 1999;Cristofoli et al, 2010), including those associated with forest disturbances (Pearce & Venier, 2006;Gillette et al, 2008). In a preliminary study in British Columbia, spider families displayed high habitat specificity , and spider assemblages responded differently relative to different types of habitat disturbances in other areas (Buddie et al, 2000;Larrivee et al, 2005).…”
