Cryoconite is a mixture of mineral and organic material covering glacial ice, playing important roles in biogeochemical cycles lowering the albedo glacier surface. Understanding differences structure cryoconite across globe can be recognizing past future changes supraglacial environments ice-organisms-minerals interactions. Despite worldwide distribution over century studies, basic characteristics cryoconite, including its forms geochemistry, remain poorly studied. The major purpose our...

Habitat loss threatens large mammals worldwide, and their survival will depend on habitat in human-dominated landscapes. Conservation planners thus face the challenge to identify areas of least conflict with land use, yet broadscale species distribution models rarely incorporate real landscape patterns nor do they potential conservation conflicts. An excellent example such challenges is provided by European bison (Bison bonasus). Almost extinct early 20th century, can only survive wild if...

Abstract The worldwide distribution of microinvertebrates on glaciers, the coldest biome, is poorly known. Owing to their tolerance hostile conditions, small size and dispersal abilities, nematodes, tardigrades rotifers are considered cosmopolitan together inhabit various ecosystems. In this study, we investigated global in cryoconite holes – a type freshwater reservoir forming directly glacial ice that creates biodiversity hotspots glaciers. We analysed samples (using classical microscopic...

Summary 1. Where populations are confined to fragmented, human‐dominated landscapes, preventing declines and extirpations will often rely on metapopulation management. Spatially‐explicit population viability analyses provide tools evaluate how well the local management efforts can be combined conserve metapopulations across large areas. Yet, models have rarely been with assess cost‐effectiveness of different conservation strategies. 2. European bison Bison bonasus only occur in small,...

Abstract Pseudechiniscus is a morphologically homogeneous genus of tardigrades. The morphological features commonly used for species discrimination in this are the dorsal sculpture, shape and number plates trunk appendages.

All similar their general appearance all lack Moreover, not only nominal suillus, but also other members have been insufficiently described. In our study, we examined several populations from...

Studies on Antarctic tardigrades started at the beginning of twentieth century and have progressed very slowly ca. 75 tardigrade species are known from this region. Paramacrobiotus fairbanksi was described USA based genetic markers later reported Italy, Poland, Spain. The “everything is everywhere” hypothesis suggests that microscopic organisms specific features which help them to inhabit most environments due they can be considered cosmopolitan.

Abstract Microbes play a critical role in plant litter decomposition and influence the fate of carbon rivers riparian zones. When decomposing low‐nutrient litter, microbes acquire nitrogen (N) phosphorus (P) from environment (i.e., nutrient immobilization), this process is potentially sensitive to loading changing climate. Nonetheless, environmental controls on immobilization are poorly understood because rates also influenced by chemistry, which coupled same factors. Here we used...

We discovered a 50-cm-thick peat deposit near Cape Rasmussen (65.2°S), in the maritime Antarctic. To our knowledge, while aerobic 'moss banks' have often been examined, waterlogged 'peatlands' never described this region before. The system is approximately 100 m2, with shallow water table. Surface vegetation dominated by Warnstorfia fontinaliopsis, wet-adapted moss commonly found Antarctic Peninsula. Peat inception was dated at 2750 cal. BP and followed relatively rapid accumulation (~0.1...

Pseudechiniscus is a morphologically homogeneous heterotardigrade genus with relatively low number of morphological features useful for the species discrimination. The suillus-facettalis complex are some most challenging tardigrades to identify. Here, we examine several populations from Antarctica, Italy, Madagascar and Norway that would have likely been attributed Pse. suillus prior recent redescription species. Populations were analysed using integrative taxonomy—a combination classical...
