“…This Austrian study found H. rufipes the most abundant species too, but P. cupreus was captured in notably larger abundance than in our experiment. Our study confirmed the presence of carabid species that are usually found along the edges of forests (Roume et al, 2011), namely Anchomenus dorsalis (Pontoppidan), Trechus quadristriatus (Schrank). The number of these species was relatively low, as they are not among the most important species of arable lands and are assumed to have been attracted into our experimental potato plots by of the presence of the organic mulching material.…”

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.

“…We found it in the largest number on plots covered with leaf litter mulch but it was hardly found on unmulched plots. One of the most frequent species of the Budaörs location, B. crepitans (Roume et al, 2011), which prefers open habitats, was found in large numbers on plots mulched with hay and was scarcely found on unmulched plots.…”

“…Together with enhancing flower‐visiting insects and associated pollination services, logging could promote the provision of other ecosystem services, such as biological control by natural enemies of pest insects (Holland & Fahrig, ; Roume et al ., ). At the same time, the aesthetic and thus the recreational value of the landscape could be enhanced by well‐planned ecotone management (Tahvanainen et al ., ; Hietala‐Koivu et al ., ).…”

1. Mitigation tools aimed at counteracting the loss of farmland insect diversity and associated ecosystem services are usually conducted on cultivated fields. Possibilities of managing field-forest ecotones for biodiversity have been rarely discussed, despite their importance for flower-visiting insects.2. The effectiveness of logging in enhancing three aspects of insect diversity (bumblebee abundance, total species richness, and habitat specialist butterfly abundance) and changes in insect community composition were studied in a three-year field experiment. The study included 15 field-forest ecotones, each with a 50 m long and 25 m wide treated area and a corresponding control. At forest edge, a 5 m wide strip was clear-cut and behind this strip, a 20 m wide belt was thinned to a basal area of 8 m 2 ha À1 .3. Logging simultaneously promoted all three aspects of insect diversity. Changes were more apparent at clear-cut edge than in the thinned interior. Community composition changed via increased abundance of open habitat species, especially butterflies. 4. Logging promoted warm microclimates and flower availability at clear-cut edges. All three aspects of insect diversity showed a positive response to flower coverage, which in turn was negatively correlated with the amount of logging residue.5. Creating open field-forest ecotones is beneficial for flower-visiting insects and open habitat species in particular. This approach is expected to be most beneficial at sunny forest edges and sites which become overgrown slowly. In addition, we suggest logging residue to be removed when aiming to promote flower-visitors.

BioRisk 13: 1-29. https://doi.org/10.3897/biorisk.13.22316 AbstractInsect conservation is challenging on various ecological scales. One largely neglected aspect is the quality of undisturbed hibernation sites. This study aims to fill a lack of knowledge concerning insect hibernation on uncut meadows persisting in urban green spaces during the winter season in a middle-sized town in south Germany. During two years of sampling, 13,511 insect specimens of the orders Heteroptera, Hymenoptera, Coleoptera and Diptera were caught from their winter stands. The specimens were assigned to 120 families and 140 taxonomic species were determined from the orders Heteroptera, Coleoptera and Diptera and 324 morphotypes from the orders Hymenoptera, Coleoptera and Diptera. The data indicate the importance of winter fallows for insect hibernation. Unmown meadows offer additional plant structures in winter (flower heads, stems, tufts and leaves) that are absent from mown ones. This increased structural diversity results in both higher species diversity and numbers of insect individuals during spring emergence. The results of this study thus emphasise the value of unmown structures for insect conservation and suggest a mosaic-like cutting maintenance of meadows, way-and river-sides and other green infrastructure in both the urban area and the open landscape.
