Determining diet is a key prerequisite for understanding species interactions, food web
structure and ecological dynamics. In recent years, there has been considerable …

Northern ecosystems are experiencing some of the most dramatic impacts of global change
on Earth. Rising temperatures, hydrological intensification, changes in atmospheric acid …

Arctic rivers provide an integrated signature of the changing landscape and transmit signals
of change to the ocean. Here, we use a decade of particulate organic matter (POM) …

An important question in the context of climate change is to understand how CH4 production
is regulated in anoxic sediments of lakes and reservoirs. The type of organic carbon (OC) …

Water browning or brownification refers to increasing water color, often related to increasing
dissolved organic matter (DOM) and carbon (DOC) content in freshwaters. Browning has …

Inland water carbon (C) sequestration rates play a potentially important role in the balance
between C supplies from the atmosphere and associated watersheds and the net demand of …

We here review the ecological role of essential nutritional biomolecules [fatty acids (FA),
amino acids (AA), sterols, vitamins] in aquatic and terrestrial food webs, encompassing the …

In many dry parts of the world, salinization of water resources threatens freshwater
biodiversity and the livelihood of people. However, ecological impact studies remain scarce …

Abstract The River Continuum Concept implies that consumers in headwater streams have
greater dietary access to terrestrial basal resources, but recent studies have highlighted the …

Global environmental changes are causing widespread nutrient depletion, declines in the
ratio of dissolved inorganic nitrogen (N) to total phosphorus (DIN: TP), and increases in both …
