Abstract The Arctic experiences climate changes that are among the fastest in world and affect all Earth system components. Despite expected increase terrigenous inputs to Ocean, their impacts on biogeochemical cycles currently largely neglected IPCC-like models. Here we used a state-of-the-art high-resolution ocean biogeochemistry model includes carbon nutrient from rivers coastal erosion produce twenty-first-century pan-Arctic projections. Surprisingly, even with an anticipated rise primary production across wide range of emission scenarios, our findings indicate change will lead counterintuitive 40% reduction efficiency Arctic’s biological pump by 2100, which contribute 10%. Terrigenous also drive intense CO 2 outgassing, reducing Ocean’s sink at least 10% (33 TgC yr −1 ). These unexpected reinforced feedback, mostly due accelerated remineralization rates, lower capacity for sequestering carbon.

Water browning or brownification refers to increasing water color, often related dissolved organic matter (DOM) and carbon (DOC) content in freshwaters. Browning has been recognized as a significant physicochemical phenomenon altering boreal lakes, but our understanding of its ecological consequences different freshwater habitats regions is limited. Here, we review the on habitats, food webs aquatic-terrestrial habitat coupling. We examine global trends DOM/DOC, use remote sensing tool investigate from local scales. Studies have focused lakes rivers while seldom addressing effects at catchment scale. Other such small temporary waterbodies overlooked, making study entire network incomplete. While past research investigated response primary producers, aquatic invertebrates fishes, macrophytes, invasive species, understudied. Research without considering fluxes between terrestrial habitats. highlight importance how changes one may cascade another. broader than heretofore concentration region. Overall, propose that future studies improve through following actions: 1) knowledge processes other wetland types rivers, 2) assessing impact multiple scales, 3) examining coupling, 4) expanding scale, 5) using consequences.

Human impacts, particularly nutrient pollution and land-use change, have caused significant declines in the quality quantity of freshwater resources. Most global assessments concentrated on species diversity composition, but effects multifunctionality streams rivers remain unclear. Here, we analyse most comprehensive compilation stream ecosystem functions to date provide an overview responses uptake, leaf litter decomposition, productivity, food web complexity six globally pervasive human stressors. We show that stressors inhibited functioning for stressor-function pairs. Nitrate uptake efficiency was affected by 347% due agriculture. However, concomitant negative positive were common even within a given pair. Some part this variability effect direction could be explained structural heterogeneity landscape latitudinal position streams. Ranking their absolute revealed all studied stressors, with wastewater effluents (194%), agriculture (148%), urban land use (137%) having strongest effects. Our results demonstrate are at risk losing functional backbone if persist contemporary intensity, freshwaters critical services humans rely on. advocate more studies multiple improve understanding impacts. Finally, management must shift its focus toward ecological function-based approach needs develop strategies maintaining or restoring rivers.

Anthropogenic land use has increased nutrient concentrations and altered dissolved organic matter (DOM) character its bioavailability. Despite widespread recognition that DOM reactivity can vary temporally, the relative influence of stream order on characteristics is poorly understood across seasons entire flow regime. We examined 28-day bioavailable carbon (BDOC) a river network to determine roles in driving variability bioavailability throughout year. 1st-order streams was distinct from higher orders with lower DOC concentrations, less aromatic (specific ultraviolet absorbance at 254 nm (SUVA254)), more autochthonous (fluorescence index), recently produced (β/α) DOM. Across all months, primarily explained by use, rather than or season. Land most variation transitional winter months least during dry months. BDOC greater watersheds (SUVA254) recent allochthonous development impervious surface. With continued development, smallest impacted expected increase.

Abstract Despite our growing understanding of the global carbon cycle, scientific consensus on drivers and mechanisms that control dissolved organic (DOC) turnover in aquatic systems is lacking, hampered by mismatch between research approaches DOC reactivity from either intrinsic (inherent chemical properties) or extrinsic (environmental context) perspectives. Here we propose a conceptual view which combination factors controls rates determines reactions will occur. We review three major types (biological, photochemical, flocculation) an perspective further define environmental features modulate expression chemically inherent potential. Finally, hypotheses how together shape patterns across land‐to‐ocean continuum, underscoring there no without context. By acknowledging intrinsic–extrinsic duality, framework intends to foster improved modeling its impact ecosystem services.
