Permafrost thaw lakes are a subject of increasing research interest given their abundance across the northern landscape. Our aim in the present study was to characterize the photosynthetic communities in a range of subarctic thaw lakes using a combination of HPLC analysis of algal and bacterial pigments, flow cytometry and molecular analysis. Our results showed that the thaw lakes contain diverse phototrophic communities and are a previously unrecognized habitat for abundant picophotoautotrophs.

The MALINA oceanographic expedition was conducted in the Mackenzie River and the Beaufort Sea systems. The sampling was performed across seven shelf–basin transects to capture the meridional gradient between the estuary and the open ocean. The main goal of this research program was to better understand how processes such as primary production are influencing the fate of organic matter originating from the surrounding terrestrial landscape during its transition toward the Arctic Ocean.

Meltwater runoff trapped by an ice shelf can create a freshwater lake floating directly on seawater. We show that the depth of the freshwater–seawater interface varies substantially due to changes in meltwater inflow and drainage under the ice shelf. By accounting for seasonality, the interface depth can be used to monitor long-term changes in the thickness of ice shelves. We show that the Milne Ice Shelf, Ellesmere Island, was stable before 2004, after which time the ice shelf thinned rapidly.

Subarctic lakes are changing in size as a result of permafrost thawing, resulting in mobilization of soil materials. Our study characterizes the carbon and nutrient regime of a set of thaw lakes and their adjacent permafrost soils in a rapidly degrading landscape, showing how these materials create favorable conditions for aquatic bacterial communities. We discuss the controls over the bacterial community, and demonstrate that gain processes are not a primary control.

In this review, we give an overview of the current state of knowledge regarding how permafrost thaw affects aquatic systems. We describe the general impacts of thaw on aquatic ecosystems, pathways of organic matter and contaminant release and degradation, resulting emissions and burial, and effects on ecosystem structure and functioning. We conclude with an overview of potential climate effects and recommendations for future research.

Studies have found excessive re-vegetation causes negative environmental effects in the agro-pastoral ecotone of northwest China, while the latest national ecological project plans to expand grasslands to 60 %. Therefore incorporating an appropriate mixture of land use/cover into decision-making is urgently required. Thus, this paper identified the proper land use/cover pattern within the local hydrological and climatic metrics, for the first time, among scenarios simulated by CLM 5.0.

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.

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.

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.

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
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.
