“…Many studies have found a positive relationship between plant species richness and predatory invertebrate richness as measured by species richness or diversity indices such as the Shannon-Weaver diversity index (Crisp et al, 1998;Siemann et al, 1998;Knops et al, 1999;Jonas et al, 2002). However, some studies have contradicted these results.…”

a b s t r a c tIn recent decades, agricultural producers and non-governmental organizations have restored thousands of hectares of former cropland in the central United States with native grasses and forbs. However, the ability of these grassland restorations to attract predatory invertebrates has not been well documented, even though predators provide an important ecosystem service to agricultural producers by naturally regulating herbivores. This study assessed the effects of plant richness and seeding density on the richness and abundance of surface-dwelling (ants, ground beetles, and spiders) and aboveground (ladybird beetles) predatory invertebrates. In the spring of 2006, twenty-four 55 m × 55 m-plots were planted to six replicates in each of four treatments: high richness (97 species typically planted by The Nature Conservancy), at low and high seeding densities, and low richness (15 species representing a typical Natural Resources Conservation Service Conservation Reserve Program mix, CP25), at low and high seeding densities. Ants, ground beetles, and spiders were sampled using pitfall traps and ladybird beetles were sampled using sweep netting in [2007][2008][2009]. The abundance of ants, ground beetles, and spiders showed no response to seed mix richness or seeding density but there was a significant positive effect of richness on ladybird beetle abundance. Seeding density had a significant positive effect on ground beetle and spider species richness and Shannon-Weaver diversity. These results may be related to differences in the plant species composition and relative amount of grass basal cover among the treatments rather than richness.Published by Elsevier B.V.

“…This capture method is widely used by many experts in the Czech Republic as well as in Europe for decades (Adis, 1979;Absolon et al, 1994;Kůrka, 1982;Jonas et al, 2002;Larsen et al, 2003;Raemakers et al, 2001;Kwiatkovski, 2011 etc.). On the other hand, this method is non-standard for weevils and leaf beetles.…”

The number of remarkable species on a locality is an important indicator of locality value. The ecological requirements of the rare species may help to target correct landscape management activities. Our objective was to fi nd out if standardly used capture methods for diff erent group of invertebrate are able to detect really representative composition of species including rare taxa. Our experiment was carried out at the Moravský kras Protected Landscape Area (Macošská and Vilémovická stráň slope) where secondary dry grasslands are typical for each investigated locality. We used fi ve groups of invertebrates (spiders, ground beetles, rove beetles, leaf beetles and weevils) and three capture methods (pitfall traps, sweeping on vegetation and yellow Möricke traps). Arthropods were determined and classifi ed according to their rarity. Using the three capture methods, we obtained in total 127 spider species (Areneae), 31 ground beetle species (Carabidae), 29 rove beetle species (Staphylinide), 52 leaf beetle species (Chrysomelidae) and 55 weevil species (Curculionidae). Results showed that the diff erent capture methods signifi cantly infl uenced number of detected remarkable species. It was statistically proved for spiders (P = 0.025), weevils (P = 0.038) and marginally also for rove beetles (P = 0.051). Spiders of climax (C species) and semi-natural (SN species) habitats were rather detected by pitfall traps, whereas spiders of disturbed habitats were collected by sweeping on vegetation and Möricke yellow pans eventually. Relict species of weevils (R species) were detected by pitfall traps, typical species (T species) were collected by Möricke yellow pans and expansive species (E species) were found by sweeping on vegetation.

“…Invertebrate abundance and taxonomic composition in grassland and woodland ecosystems are known to vary widely in response to changes in precipitation, temperature, plant biomass, and land management (Jonas et al 2002, SaintGermain et al 2005. Invertebrates are closely tied to changes in plant species diversity and structural complexity (Dennis et al 1998, Siemann et al 1998, and although not always reaching significance, our post hoc analyses were consistent with these findings in 2006.…”

Abstract. Woody plant encroachment is a worldwide phenomenon in grassland and savanna systems whose consequence is often the development of an alternate woodland state. Theoretically, an alternate state may be associated with changes in system state variables (e.g., species composition) or abiotic parameter shifts (e.g., nutrient availability). When statevariable changes are cumulative, such as in woody plant encroachment, the probability of parameter shifts increases as system feedbacks intensify over time. Using a Before-After Control-Impact (BACI) design, we studied eight pairs of grassland sites undergoing various levels of eastern redcedar (Juniperus virginiana) encroachment to determine whether responses of flora and fauna to experimental redcedar removal differed according to the level of pretreatment redcedar cover. In the first year after removal, herbaceous plant species diversity and evenness, woody plant evenness, and invertebrate family richness increased linearly with pretreatment redcedar cover, whereas increases in small-mammal diversity and evenness were described by logarithmic trends. In contrast, increases in woody plant diversity and total biomass of terrestrial invertebrates were accentuated at levels of higher pretreatment cover. Tree removal also shifted small-mammal species composition toward a more grasslandassociated assemblage. During the second year postremoval, increases in herbaceous plant diversity followed a polynomial trend, but increases in most other metrics did not vary along the pretreatment cover gradient. These changes were accompanied by extremely high growingseason precipitation, which may have homogenized floral and faunal responses to removal. Our results demonstrate that tree removal increases important community metrics among grassland flora and fauna within two years, with some responses to removal being strongly influenced by the stage of initial encroachment and modulated by climatic variability. Our results underscore the importance of decisive management for reversing the effects of woody plant encroachment in imperiled grassland ecosystems.
