Short summary
In cold regions of the Earth, thawing permafrost can change the landscape, impact ecosystems, and lead to the release of greenhouse gases. In this study we used many observational tools to better understand how sediment moves on permafrost hillslopes. Some topographic change conforms to our understanding of slope stability and sediment transport as developed in temperate landscapes, but much of what we observed needs further explanation by permafrost-specific geomorphic models.

Widely-used land models project near-surface drying of the terrestrial Arctic despite increases in the net water balance driven by climate change. Drying was generally associated with increases of active-layer depth and permafrost thaw in a warming climate. However, models lack important mechanisms such as thermokarst and soil subsidence that will change the hydrological regime and add to the large uncertainty in the future Arctic hydrological state and the associated permafrost carbon feedback.

At the foot of the Himalayas in Nepal, land cover time series and data of environmental drivers show changes in disturbance-dependent grasslands that serve as habitat for endangered megafauna. The changes in surface area and heterogeneity of the grassland patches are attributed to a relocation of the dominant river channel of the Karnali River and associated decline of hydromorphological disturbances and a decrease in anthropogenic disturbances after its establishment as conservation area.

We evaluate the relationships between geodiversity, limnological conditions, and freshwater ostracodes from southern Mexico to Nicaragua. Geological, limnological, geochemical, and mineralogical characteristics of 76 systems reveal two main limnological regions and seven subregions. Water ionic and sediment composition are the most influential. Geodiversity strongly influences limnological conditions, which in turn influence ostracode composition and distribution.

Cryoconite holes are ponds on the glacier surface that play an important role in glacier nutrient pathways. This paper presents the first description of the carbon and nitrogen isotopic composition of cryoconite consumers (tardigrades and rotifers) and their potential food. We showed that consumers differ in nitrogen isotopes and carbon isotopes vary between taxa and between glaciers. The study contributes to improving knowledge about cryoconite hole functioning and cryoconite trophic networks.

Across North America and Europe, goose populations have increased exponentially in response to agricultural intensification. By using an experimental approach, we empirically demonstrated that geese act as bio-vectors, making terrestrial nutrients more bioavailable to freshwater systems. The study revealed that the nutrient loading from goose faeces has the potential to change phytoplankton community composition, with a shift toward an increased presence of cyanobacteria.

Based on classical concepts in ecology, and a literature survey, we highlight the importance of flooded land as a preferential source of atmospheric carbon to aquatic systems at the global scale. Studies in terrestrial and aquatic ecosystems could be reconciled by considering the occurrence of an efficient wetland CO2 pump to river systems. New methodological approaches coupling hydrology and ecology are also necessary to improve scientific knowledge on carbon fluxes at the land–water interface.

How environmental change affects a species' phenotype is crucial for taxonomy and biodiversity assessments and for their application as paleoecological indicators. Morphometric data of a Neotropical ostracod species, as well as several climatic and hydrochemical variables, were used to investigate the link between morphology and environmental conditions. Temperature seasonality, annual precipitation, and chloride and sulphate concentrations were identified as drivers for ostracod ecophenotypy.

The diversity of microalgae and cyanobacteria in cryoconites on three high-Arctic glaciers was investigated. Possible bottom-up controls via nutrient limitation, wind dispersal, and hydrological stability were measured. Grazer populations were quantified to estimate the effect of top-down controls. Nutrient limitation appeared to be the most important control on the diversity and competition outcomes of microalgae and cyanobacteria.

Thaw ponds and lakes varied in their bacterial community structure. A small number of taxa occurred in high abundance and dominated many of the communities. Nevertheless, there were taxonomic differences among different valleys implying some degree of habitat selection. Association networks were composed of a limited number of highly connected OTUs. These "keystone species" were not merely the abundant taxa, whose loss would greatly alter the structure and functioning of these aquatic ecosystem.

Based on our molecular data and performed analyses we found that the gastropods studied represent a comparatively old group that most likely evolved with a constant rate of diversification. However, preliminary data of the SCOPSCO deep-drilling program indicate signatures of environmental/climatic perturbations in Lake Ohrid. We therefore propose that the constant rate observed has been caused by a potential lack of catastrophic environmental events and/or a high ecosystem resilience.

Terrestrial inputs are considered the major driver of longitudinal patterns of nutrient concentration. Yet we show that longitudinal trends result from hydrological mixing with terrestrial inputs and in-stream processes. We challenge the idea that nutrient concentrations decrease downstream when in-stream net uptake is high. Conversely, in-stream processes can strongly affect stream nutrient chemistry and fluxes even in the absence of consistent longitudinal trends in nutrient concentration.

Under UVR and stratification,the commensalistic algae-bacteria interaction was strengthened in the high-UVR lake, where excretion of organic carbon rates exceeded the bacterial carbon demand,but did not occur in the low-UVR lake.The greater UVR damage to algae and bacteria and the weakening of their commensalistic interaction found in the low-UVR lake indicates these lakes would be especially vulnerable to UVR. These results have implications for the C cycle in lakes of the Mediterranean region.

Short summary
Aquatic tundra plants dominate productivity and methane fluxes in the Arctic coastal plain. We assessed how environmental nutrient availability influences production of biomass and greenness of aquatic tundra. We found phosphorous to be the main nutrient limiting biomass productivity and greenness in Arctic aquatic grasses. This study highlights the importance of nutrient pools and mobilization between terrestrial–aquatic systems and their influence on regional carbon and energy feedbacks.
Aquatic tundra plants dominate productivity and methane fluxes in the Arctic coastal plain. We...
