“…Our results agree with those of other similar studies, which suggest that the composition of beetles present at a site is related to environmental factors such as vegetative physiognomy (vegetation age, diversity, height and density) (Watts & Gibbs 2002;Grimbacher & Catterall 2007), presence of dead wood on the ground (Reay & Norton 1999) and LD (Sanderson et al 1995). With increasing age, restored plant communities in a mined peat bog at Torehape (35 km east of Whangamarino) become more diverse and structurally complex, resulting in the beetle community composition converging rapidly on the target community structure of an undisturbed peat bog (Watts et al 2008).…”

We investigated the effects of invasion by introduced grey willow (Salix cinerea) on beetle communities within four wetland vegetation types: native vegetation, native vegetation following grey willow removal, native vegetation undergoing grey willow invasion and dense grey willowdominated vegetation. In total, 1505 beetles from 90 species were collected using modified Malaise traps. Native wetland vegetation had significantly lower beetle species richness than willow-dominated vegetation and was dominated by herbivores, whereas detritivores characterised willow-dominated vegetation. Beetle abundance was highest in the willow-dominated vegetation and mostly comprised detritivores. In contrast, beetle abundance was lowest in native wetland vegetation, but had even proportions of herbivores and detritivores. Native wetland vegetation had a high proportion of native beetles present. As grey willows invaded, introduced beetles became more common. The beetle community composition differed significantly between grey willow-dominated vegetation and native wetland vegetation. These compositional differences were mainly due to the increasing complexity of vegetation structure following grey willow invasion. The beetle communities within restored native wetland vegetation were most similar to those within the native wetland vegetation. From a conservation perspective, these results are encouraging and suggest that, although grey willows dramatically alter the composition of beetle communities present, these communities can be restored to a beetle fauna that is similar to those found within native wetland through the removal of the willows.

“…This highlights the very low dispersal abilities of at least some flightless species, even though apparently hospitable habitats. However, it is likely that given sufficient time such dispersal limitation could be overcome and flightless species would colonise (Grimbacher and Catterall 2007). The length of time required for this to occur is likely to be much greater, however, in landscapes that are more fragmented than those seen on the SPTA, i.e.…”

Effects of vegetation structure and floristic diversity on detritivore, herbivore and predatory invertebrates within calcareous grasslands

Calcareous grasslands in Europe have shown wide scale declines in their extent and quality as a result of modern agricultural practices, increased atmospheric eutrophication and lack of management. In addition to being a key habitat for specialist plants, calcareous grasslands are also important for many threatened invertebrates. In this UK based study, we investigated the impact of military vehicle activity, floral species richness and vegetation structure on assemblages of detritivore, herbivore and predatory invertebrates. We also consider the impact that disturbance by military vehicle activity on the proportion of invertebrate species capable of flight, a surrogate for dispersal ability. Sward height was negatively correlated with detritivore, herbivore and predator species richness. Herbivores species richness was positively correlated with both forb and grass species richness. Spatial variation in the number of plant species was negatively correlated with herbivore species richness. Those sites most heavily disturbed by military vehicle activity supported the lowest proportions of flightless invertebrates. Successful management for calcareous grassland invertebrates should aim to maintain short swards with high floristic diversity, in terms of both the forbs and grasses. It should be noted, however, that these findings refer to principally surface rather than sward active invertebrates. While disturbance associated with military vehicle activity was not found to affect invertebrate species richness, it has negative consequences for the structure of invertebrate assemblages by selecting against invertebrates with low dispersal ability. To support invertebrate diversity in calcareous grasslands we emphasise the need for variety in the timing and type of management applied to promote heterogeneity in sward structure.

“…However, recent studies investigating faunal recovery have shown that other variables besides vegetation per se can influence its return (e.g. connectivity, composition of the surrounding landscape, regional species pool, biotic factors) (Brudvig, 2011;Grimbacher and Catterall, 2007;Majer, 2009). Even less is known about the recovery of ecological functions provided by biological diversity (Brudvig, 2011;Cadotte et al, 2011).…”
