Soil Functionality Undermined by Symbiotic Fungal Decline Following Forest ConversionNARA Subscribed
The conversion of native forests to other terrestrial ecosystems represents a profound form of land‐use change, threatening aboveground biodiversity and biomass. However, its impact on soil ecological functions remains uncertain, particularly the regulatory role of soil microbial communities. To address this, we evaluated soil functionality related to carbon, nitrogen and phosphorus cycling by measuring nine enzyme activities...
Several legal acts mandate that management agencies regularly assess biological populations. For species with distinct markings, these assessments can be conducted noninvasively via capture‐recapture and photographic identification (photo‐ID), which involves processing considerable quantities of photographic data. To ease this burden, agencies increasingly rely on automated identification (ID) algorithms. Identification algori...
Organic matter decomposition in mountain peatlands: effects of substrate quality and peatland degradationNARA Subscribed
Background and Aims Peatlands occupy only 3% of Earth’s terrestrial lands but store about one-third of global soil carbon. However, these large carbon stocks are currently under threat due to peatland degradation, where altered hydrological balance could enhance peat oxidation; thus releasing large amounts of CO 2 into the atmosphere. We investigated the interactive effects of substrate quality, peat depth and peatland degrada...
Drought alters the functional stability of stream invertebrate communities through timeNARA Subscribed
Aim In fresh waters, most biogeographical understanding of how extreme events such as drought modify biodiversity and ecosystem functioning derives from static, spatial comparisons of ecological communities, between intact and disturbed sites or along stress gradients. Impacts of drought on the development of ecological communities over time remain poorly resolved, with information on parallel trends in community structure and...
Simulating rewetting events in intermittent rivers and ephemeral streams: A global analysis of leached nutrients and organic matterNARA Subscribed
Climate change and human pressures are changing the global distribution and the extent of intermittent rivers and ephemeral streams (IRES), which comprise half of the global river network area. IRES are characterized by periods of flow cessation, during which channel substrates accumulate and undergo physico‐chemical changes (preconditioning), and periods of flow resumption, when these substrates are rewetted and release pulse...
Variation in the diet‐tissue fractionation of stable nitrogen isotopes (Δ15N) is a major source of uncertainty in mixing model outputs and the calculation of trophic level in food web studies in aquatic systems. Using δ 15 N and δ 13 C of algae and consumers collected from a broad range of streams and rivers in Australia and New Guinea, we calculated Δ15N using a gradient approach, and compared these estimates with those from...
