Simultaneous Visualization of Enzymatic Activity in the Cytoplasm and at Polyphosphate Inclusions in Beggiatoa sp. Strain 35Flor Incubated with 18O-Labeled Water

open access: yesmSphere, 2018
Here we report on a new nanoscale secondary ion mass spectrometry (nanoSIMS) approach based on enzyme-mediated oxygen isotope exchange, which combines the visualization of general metabolic activity in the cytoplasm with insights into the activity of ...

Impact of Sovereign Debt Maturity on Fiscal Sustainability

open access: yesInternational Journal of Finance &Economics, EarlyView.
ABSTRACT This study is the first to investigate the impact of the term structure of public debt on fiscal sustainability. We adopt the widely used backward‐looking measure of fiscal sustainability—fiscal responsiveness as proposed by Bohn. Using data from De Graeve and Mazzolini and focusing on a sample of 19 most developed countries, we demonstrate ...

Risk Forecasting in Shipping Exchange‐Traded‐Fund (ETF) Markets

open access: yesInternational Journal of Finance &Economics, EarlyView.
ABSTRACT This article examines the risk properties of freight‐derivative‐based exchange‐traded funds (ETFs), focusing on the Breakwave Dry Bulk Shipping ETF (BDRY), and evaluates the accuracy of Value‐at‐Risk (VaR) and Expected Shortfall (ES) forecasts across a range of econometric models.

Examining New Donors in the OECD's Development Assistance Committee

open access: yesJournal of International Development, EarlyView.
ABSTRACT How do emerging donors integrate into the existing international aid architecture? While the existing literature focuses largely on emerging donors from the Global South, such as Brazil, China, India and Russia, there are many emerging donors from the Global North that have joined the OECD's Development Assistance Committee (DAC)—the premier ...

The world’s enclosed seas highlight the need for urgent emission reductions and societal adaptation

open access: yesCommunications Earth & Environment
Enclosed marginal seas are hotspots of endemic biodiversity that sustain societies through fisheries, tourism, and vital ecosystem services. Their small size makes them highly sensitive to global warming but systematic assessments of future climate ...

Sound speed contributions of solutes in water

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Understanding sound speed in natural waters is utilized in applications such as echo sounding, side scanning, temperature field tomography, evaluating compressibility and thermodynamic properties. While established approaches, such as the UNESCO formula and TEOS‐10 package, describe sound speed in oceanic waters, the information about the ...

Warming modifies trophic impacts of invading shrimp with impact varying among primary producers

open access: yesOikos, EarlyView.
Environmental change drivers, such as climate change and species invasions, can disrupt biological networks and weaken ecosystem stability. Acting together, these drivers may interact and alter the effects on the ecosystem. However, few studies have examined the interactive effects of climate change and species invasions, particularly in aquatic ...

In Search of a Field-Based Relationship Between Benthic Macrofauna and Biogeochemistry in a Modern Brackish Coastal Sea

open access: yesFrontiers in Marine Science, 2018
During several cruises in the southern Baltic Sea conducted in different seasons from 2014 to 2016, sediment cores were collected for the investigation of pore-water biogeochemistry and associated nutrient fluxes across the sediment-water interface.

Different demographic drivers of recovery in two adjacent populations of a long‐lived bird of prey

open access: yesOikos, EarlyView.
Understanding the demographic mechanisms underlying population decline or recovery is critical for conservation and management, yet similar population trends may arise from very different underlying processes. Comparing populations of vulnerable species groups like long‐lived raptors in different environments can reveal how species respond to change ...
