“…A dense cover of herbs may prevent the movement and food capture of the forest species, because these species are not adapted to such conditions. Similar arguments were used by Guillemain et al (1997) explaining that a thick litter layer resulted in a decreased abundance and number of species of the carabids.…”

The impacts of non-native Norway spruce plantation on the abundance and species richness of carabids were studied in the Bükk National Park in Hungary, central Europe. Pitfall catches from recently established (5 yr old), young (15 yr after planting), middle-aged (30 yr after planting), old Norway spruce Picea abies plantation (50 yr after planting), and a native submontane beech forest (Fagetum sylvaticae) as a control stand were compared. Our results showed that deciduous forest species decreased significantly in abundance in the plantations, and appeared in high abundance only in the native beech forest. Furthermore, open habitat species increased remarkably in abundance in the recently established plantation. Carabids were significantly more abundant and species rich in the native forest than in the plantations, while differences were not significant among the plantations. Multiple regression between the abundance and species richness of carabids and twelve environmental measurements showed that pH of the soil, herb cover and density of the carabids’ prey had a significant effect in determining abundance and species richness. Our results showed that plantation of non-native Norway spruce species had a detrimental effect on the composition of carabid communities and no regeneration could be observed during the growth of plantations even 50 yr after the establishment. This emphasises the importance of an active nature management practice to facilitate the recolonization of the native species

“…The reason of the similarity in diversity of carabids might be the small size of the plots or that the quality of cover is less important for ground beetles than the presence or absence of a shelter (and it seems that mulch as a soil cover that imitates the natural layer of decaying plant material is accepted as shelter). One must also note that the abundancy of potential prey also plays an important factor in the abundance and diversity of carabid beetles of an area (Guillemain et al, 1997). According to our study, year had no effect on the diversity of carabid beetles ( Figure 2).…”

“…Another study on the carabid fauna in France found that the thickness of the leaf litter influences the density of Abax ater, Villers, as it may be harder for a carabid predator to catch the prey under a thick layer of leaf litter. This study indicated that the thicker the layer, the lower the number of carabid beetles was (Guillemain et al, 1997). That fenomenon may appear in mulched fields as well, since the width of leaf litter is increased.…”

The effect of mulching on the abundance and diversity of ground beetle assemblages in two hungarian potato fields

Abstract:The benefits of mulching in potato (Solanum tuberosum L.) production are manifold, such as it provides shelters for natural enemies of pests. The aim of our study was to detect the effect of two organic mulch types on the abundance, diversity and species composition of carabid beetles. Our potato plots were located in two sites with similar habitats including similar soil characteristics. Each plot was treated with hay and leaf litter mulch (hay, leaf, control) with 4 replications at each site. It resulted in 24 samples in each study site annually. Carabid beetles were collected by using pitfall traps in between 2011-2013. We found that due to mulching a larger and more diverse carabid population occurred on potato plots. Both mulching types increased the total number of carabids captured having a 17% higher abundance on hay mulched plots and 14% higher abundance on leaf litter mulched plots. According to the results 28 % of the collected species was found only on mulched plots, whereas only 13 % of the captured species were found only on unmulched areas. For some of the species, especially for Brachinus crepitans (L.), the number of individuals was significantly higher on mulched plots. The two different mulching materials had very similar effects on assemblages of carabid species. The species composition of ground beetles was considerably affected by the two locations, and to a lesser extent by the different time periods. While the dominant species of Budaörs was B. crepitans, the most abbundant carabid beetle at Hidegkút belonged to genus Harpalus. Neither hay nor leaf litter were able to constantly increase the biodiversity of the carabid assemblages on potato plots, because the effect of the two years overwrote the between-treatment effects on carabid diversity. The positive effect of organic mulching on carabid diversity however, was found significant in both years of 2011 and 2012.

“…The positive relationship between the number of generalist species and the cover of leaf litter is surprising, because Guillemain et al (1997) showed that the number of habitat generalist carabid species could decrease by increasing the amount and thickness of leaf-litter. Perhaps the thick leaf litter may offer new niches, for example, by providing space for the vertical separation of the coexisting species.…”

Several managed native forest stands have been reforested with conifer trees inEurope during recent centuries. These habitat alterations have influenced ground-dwelling invertebrates. We studied carabid beetle assemblages from a native beech forest (70-y-old), and a recently established (5-y-old), a young (15-y-old), a middle-aged (30-y-old) and a mature (50-y-old) Norway spruce plantation by pitfall trapping to explore the effect of reforestation on carabid beetles. The total number of carabid species, and the forest species were highest in the beech forest. The number of open-habitat species was highest in the youngest, relatively open monoculture. Ordination also confirmed changes in carabid composition with change in the studied habitats. Newly proposed forest affinity indices, based on species specificity, fidelity, and on a combination of specificity and fidelity were significantly higher in beech forest than in spruce plantations. We found these affinity indices especially useful in revealing the ecological character of the studied carabid assemblages. Regression analyses showed that leaf litter cover, herbs, shrubs, canopy closure and prey abundance were related to the structure of carabid-beetle assemblages.
