A comprehensive database of paleoclimate records is needed to place recent warming into the longer-term context natural climate variability. We present a global compilation quality-controlled, published, temperature-sensitive proxy extending back 12,000 years through Holocene. Data were compiled from 679 sites where time series cover at least 4000 years, are resolved sub-millennial scale (median spacing 400 or finer) and have one age control point every 3000 with cut-off values slackened in...
Abstract Quantifying the relative importance of how local (environmental or niche‐based) and regional (dispersal‐related spatial) processes regulate assembly communities has become one main research avenues community ecology. It been shown that degree isolation habitats in landscape may substantially influence role environmental filtering dispersal‐related metacommunities. Dendritic stream networks are unique landscape, where more isolated upstream sites have predicted to be primarily...
We present a Holocene summer air temperature reconstruction based on fossil chironomids from Lake Brazi (1740 m.a.s.l.), shallow mountain lake in the South Carpathians. Summer was performed using transfer functions Swiss (Sw-TF) and merged Norwegian–Swiss calibration data set (NS-TF). Our results suggest that temperatures increased rapidly onset of early onwards ( ca. 11,500–10,200 cal. yr BP), reaching close to July (~11.2°C). Between 10,200 8500 BP mean reconstructed further by 1.5–2.0°C....
Late glacial and early Holocene summer temperatures were reconstructed based on fossil chironomid assemblages at Lake Brazi (Retezat Mountains) with a joint Norwegian"Swiss transfer function, providing an important addition to the late quantitative climate reconstructions from Europe. The pattern of temperature changes in show both similarities some differences NGRIP δ 18 O record other European chironomid-based reconstructions. Our reconstruction indicates that (1740 m a.s.l.) air increased...
Two high-altitude lake-sediment sequences (Lake Lia, 1910 m a.s.l. and Lake Bucura, 2040 a.s.l.) from the Retezat Mountains (South Carpathians, Romania) were analysed using multi-proxy methods to study responses of treeline, timberline alpine/subalpine vegetation climate change human impact during past 16,000 years. Woody species ( Pinus mugo, cembra, Picea abies Juniperus communis) reached Lia between 12,000 11,800 cal. yr BP, whereas P. mugo colonised shores Bucura at 9600 BP. was in...
Variation in community composition and species turnover are different types of beta diversity, expressing non-directional directional changes, respectively. While changes (e.g. turnover) along geographic gradients can be studied any direction depending on the hypothesis interest to researchers, temporal only meaningfully from past present. Although a wide variety methods exist for partitioning variation related community-level phenomena such as similarity, richness difference nestedness,...
In this study we evaluate how variations in taxonomic composition and physical structure of macrophyte stands affect plant-dwelling chironomid assemblages highly variable two densely vegetated backwaters.By using multivariate explanatory techniques found that similar vegetation did not unequivocally relate to assemblages, moreover the diversity correlate with backwaters investigated.Taxonomic structural characteristics had little influence on or functional (i.e.feeding groups) inhabiting...
Circumalpine lakeside settlements have been declared Unesco world heritage in 2011. Their importance is mainly due to waterlogged preservation of organic material and hence the outstanding potential these sites for performing detailed archaeological studies prehistoric societies. However, details taphonomic processes (depositional environment, development anoxia, lateral or vertical displacement objects, etc.) rarely studied. Consequently, interpretations based on find distributions...
In temperate regions, plant-dwelling chironomids can be considered as cyclic colonizers that inhabit seasonally ephemeral submerged and floating-leaved macrophytes.In this study, patterns of abundance species richness were investigated within among stands three macrophyte in oxbow lakes along the River Tisza (Hungary).Chironomids colonized macrophytes rapidly most occupied habitat before it had completely developed June.Assemblage structure particular varied considerably between plant...
