Carabid beetles and chironomid midges are two dominant cold-adapted taxa, respectively on glacier forefiel terrains and in glacialstream rivers. Although their sensitivity to high altitude climate warming is well known, no studies compare the species assemblages exhibited in glacial systems. Our study compares diversity and distributional patterns of carabids and chironomids in the foreland of the receding Amola glacier in central-eastern Italian Alps. Carabids were sampled by pitfall traps; chironomids by kick sampling in sites located at the same distance from the glacier as the terrestrial ones. The distance from the glacier front was considered as a proxy for time since deglaciation since these variables are positively correlated. We tested if the distance from the glacier front affects: i) the species richness; ii) taxonomic diversity; and iii) species turnover. Carabid species richness and taxonomic diversity increased positively from recently deglaciated sites (those ca. 160 m from the glacier front) to sites deglaciated more than 160 yrs ago (those located >1300 m from glacier front). Species distributions along the glacier foreland were characterized by mutually exclusive species. Conversely, no pattern in chironomid species richness and turnover was observed. Interestingly, taxonomic diversity increased significantly: closely related species were found near the glacier front, while the most taxonomically diverse species assemblages were found distant from the glacier front. Increasing glacial retreat differently affect epigeic and aquatic insect taxa: carabids respond faster to glacier retreat than do chironomids, at least in species richness and species turnover patterns.

Polar Urals as one of target regions of Global Observation Research Initiative in Alpine Environments (GLORIA) comprises a suite of four summits, representing an elevation gradient of alpine vegetation patterns. The sampling areas cover the summits from the tops down to the 10 m contour line and are divided into eight sections. For each section, a complete list of vascular plants and herpetobiotic arthropods was collected and resurveyed. In the period from 2001 untill 2015, the species numbers steadily increased and the total surplus of vascular plants was up to 13 species on separate summit. A general decrease in the total cover of vascular plants and changes in percentage cover of the dominant species was recorded on the permanent plots; certain species of herbs decreased and certain shrub species increased. Among the dominant species of invertebrates, ground beetles and millipedes were replaced by click beetles and spiders. After 14 years the altitudinal index calculated for vascular plants gave an average upward movement of 13.6 m, that is more pronounced than in Northern and Southern Urals. The thermophilization of the alpine plant communities of Polar Urals was found equal to 9.3% of one vegetation belt. The temperature sums obtained from data loggers demonstrate the slight tendency of increase, especially for the lower summits. IntroductionThe field sites of this study are located in the Polar Urals and constitute a part of the international long-term monitoring network GLORIA (Global Observation Research Initiative in Alpine Environments). This GLORIA initiative focuses on the alpine life zone, the area above the forestline, for tracing and understanding the response of alpine ecosystems to ongoing climate change (Pauli et al. 2015). The vascular plant species occurrence was recorded first in the year 2001 on 72 mountain summits distributed across 18 study regions in Europe, with Polar Urals among them. Since then the surveys were repeated twice, in 2008 and 2015.The Urals is a unique submeridional mountain range in Eurasia, extending over 2000 km in north-south direction from the Barents Sea and Kara Sea shores at ca. 70°N to the Pre-Aral Sea sands at ca. 48°N. The mountain range crosses several zonobiomes from arctic tundra to steppe and is, accordingly, divided into five orographic regions: Polar, Subpolar, Northern, Middle and Southern Urals (Mikhailov and Olschwang 2003). From these regions, Polar Urals is situated mainly inside the North Polar Circle and is a part of the Arctic floristic region as delimited by Yurtsev (1994). Alongside with Khibiny, Putorana Plateau and other meta-arctic mountains (Makarova et al. 2013), Polar Urals is situated at the North Polar Circle and having alpine life zone in closest contact with the arctic tundra zonobiome. That is why the results of this study are of interest for both alpine and Arctic research.In contrast to meteorological and glaciological studies, long-term observations of climate change impacts on alpine ecosystems are scarce and mainly base...

“…Parlando più in generale nel contesto europeo, la gestione delle foreste può far aumentare (Niemelä et al 1993) o diminuire la ricchezza di specie di carabidi (Magura et al 2003), oppure non avere alcun effetto su di essa (Magura et al 2000). Effettivamente la gestione forestale, modificando svariati fattori come l'umidità, l'intensità luminosa, la lettiera, la necromassa, l'eterogeneità della composizione specifica e la struttura del bosco (vedi bibliografia in Toïgo et al 2013) può influire sulla varietà di specie di coleotteri carabidi (Warnaffe & Dufrêne 2004, Negro et al 2014, Pizzolotto et al 2014. Le caratteristiche ecologico-funzionali delle diverse specie possono spiegare la loro risposta alle variazioni ambientali (Kotze & O'Hara 2003, Mazzei et al 2015.…”

IntroduzioneTra gli ecosistemi terrestri, le foreste sono quelli a maggior diversità genetica, specifica e sistematica (Lindenmayer et al. 2002). In passato, gran parte delle foreste europee sono state fortemente utilizzate , Horák et al. 2012, con interventiriconducibili a una selvicoltura intensiva -che hanno favorito una o poche specie a discapito di altre, it).Abstract: Ground beetles as indicators of past management of old-growth forests in the Sila National Park. Old-growth forests are terrestrial ecosystems with the highest level of biodiversity and the main environments for the study of conservation and dynamics of the forest system. In Mediterranean Europe, two millennia of human exploitation deeply altered the structural complexity of the native forests. Some animal groups, including insects, may be used as a proxy of such changes. In this paper we explored the possible effects of forest management on the functional diversity (species traits) of carabid beetle communities. Three old-growth forests of the Sila National Park were sampled by pitfall traps set up in pure beech, beech-silver fir and Calabrian black pine forests. In each forest, five managed vs. five unmanaged stands were considered. Managed sites were exploited until the sixties of the past century and then left unmanaged. More than 6000 carabid specimens belonging to 23 species were collected. The functional diversity in carabid groups is influenced by forest management especially in beech and beech-silver fir stands. Body size, specialized predators, endemic species and forest species were negatively affected by stand management. On the contrary, omnivorous ground beetles populations (or species) with a high dispersal power (macropterous) and large geographic distribution were positively influenced by stand management. In pine forests the old-growth community seems less sensitive to past management and more affected by soil evolution. Soil erosion and disturbance may reduce species diversity of ground beetles. Anyway, the composition of the carabid community shows that 50-60 years of forest restoration are enough for the reconstruction of a fairly diverse assemblage reflecting a "subclimax" situation.
