“…Line transects and observation plot data were pooled to increase the number of recorded adult syrphids per study site. Samplings were carried out once in mid‐June and mid‐August 2015 and 2016 at suitable weather conditions, i.e., temperature minimum 15°C (temperature is a limiting factor for adult syrphids activity; Mudri‐Stojnic, Andric, Józan, & Vujic, ), no rain and wind, dry vegetation and sunshine. Sampling time was restricted to the period of 10:00–17:00 to cover maximum pollinator activity.…”

Grasslands are often managed with different intensities in the European Alps. Studies have shown that a medium management can benefit plant and animal biodiversity in these ecosystems. However, in recent decades abandonment of extensively managed meadows is an ongoing global challenge. Syrphids (hoverflies) have been recognized as a threatened group due to environmental drivers, and these managed grasslands provide preferred habitats for them. Yet, at what extent syrphids respond to grassland management strategies is little known. We investigated whether abandonment of managed mountain meadows (mown once a year, no fertilizer use) affects syrphid abundance, richness and species assemblages. Moreover, the influence of plant richness, flower frequency and surrounding landscape on syrphids were assessed. Four managed meadows were compared with four abandoned meadows in a mountainous region in Austria. Adult syrphids were sampled over two consecutive years (June and August 2015–2016) by sweep netting using line transects and observation plots. Syrphid abundance was significantly higher in managed than abandoned meadows and increased with increasing plant richness and flower frequency across management types. Management and sampling time also significantly affected syrphid species assemblages. Syrphid richness and abundance were not influenced by surrounding landscape. We conclude that both abandoned and managed meadows provide important habitat types for syrphids. Therefore, efforts should be made to maintain both managed and abandoned meadows in order to protect syrphid species within mountainous landscapes.

Abstract:The quantification of landscape structures is an important part in many ecological analysis dealing with GIS derived satellite data. This paper introduces a new free and open-source tool for conducting landscape ecology analysis. LecoS is able to compute a variety of basic and advanced landscape metrics in an automatized way by iterating through an optional provided vector layer. It is integrated into the QGIS processing framework and can thus be used as a stand-alone tool or within bigger complex models. Finally a potential case-study is demonstrated, which tries to quantify pollinators responses on landscape derived metrics at various scales.

“…These two methods were used because they are suitable for use in alpine meadows. Moreover, these methods were studied because they are regularly used but usually separately (Frank, 1999;Sobota & Twardowski, 2004;Marcos-García et al, 2012;Mudri-Stojnić et al, 2012;Power et al, 2016;Walcher et al, 2017). The aim of the present work was to determine which of these two sampling methods recorded the most species and individuals of adult syrphids.…”

“…There were four observation sessions (60 min per meadow) both in June and August 2015 when weather conditions were suitable, i.e. minimum temperature 15°C (temperature is a limiting factor for adult syrphid activity (Mudri-Stojnić et al, 2012), no rain or wind, dry vegetation and sunshine. The time of sampling was restricted to between 10 a.m. and 5 p.m. when syrphids are most active visiting fl owers and was carried out by the same people, that is, they had the same experience of identifying syrphids.…”

The outcome of assessments of the biodiversity of a taxonomic group often depend on the sampling method. The choice of an adequate method is especially important for biomonitoring purposes. In this study, the effectiveness of two methods of sampling syrphids (Diptera: Syrphidae) is compared: observation plot method vs. line transect, both sampled by sweep netting. Altogether, 18 meadows were selected in three mountain regions in the Austrian and Swiss Alps. We recorded a signifi cantly higher abundance and richness of syrphids using the observation plot method than the line transect method in 2015. Comparing data for one region recorded in 2015 and 2016, similar results were obtained. Syrphid species assemblages were affected by sampling method in both years. More syrphid species and individuals were recorded using the observation plot method, which makes it more suitable for studies aiming at comparing differences in the numbers of adult syrphids in different grassland habitats.
