Temperature and nutrient availability play key roles in controlling the pathways and rates at
which energy and materials move through ecosystems. These factors have also changed …

Climate change and species invasions represent key threats to global biodiversity. Subarctic
freshwaters are sentinels for understanding both stressors because the effects of climate …

Ecosystem metabolism, that is, gross primary productivity (GPP) and ecosystem respiration
(ER), controls organic carbon (OC) cycling in stream and river networks and is expected to …

Streams play a key role in the global carbon cycle. The balance between carbon intake
through photosynthesis and carbon release via respiration influences carbon emissions …

Streams and rivers are important conduits of terrestrially derived carbon (C) to atmospheric
and marine reservoirs. Leaf litter breakdown rates are expected to increase as water …

Water temperatures fluctuate in time and space, creating diverse thermal regimes on river
networks. Temporal variability in these thermal landscapes has important biological and …

Global quantitative estimations of ecosystem functions are vital. Among those, ecosystem
respiration and photosynthesis contribute to carbon cycling and energy flow to food webs …

Streams are important emitters of CO2 but extreme spatial variability in their physical
properties can make upscaling very uncertain. Here, we determined critical drivers of stream …

Climate warming is expected to have large effects on ecosystems in part due to the
temperature dependence of metabolism. The responses of metabolic rates to climate …

The magnitude of Alaska (AK) inland waters carbon (C) fluxes is likely to change in the
future due to amplified climate warming impacts on the hydrology and biogeochemical …
