Albatrosses respond adaptively to climate variability by changing variance in a foraging trait.

Glob Chang Biol 2021 Jun 5. Epub 2021 Jun 5.

Centre d'Etudes Biologiques de Chizé, UMR 7372, 79360, Villiers-en-Bois, France.

The ability of individuals and populations to adapt to a changing climate is a key determinant of population dynamics. While changes in mean behaviour are well studied, changes in trait variance have been largely ignored, despite being assumed to be crucial for adapting to a changing environment. As the ability to acquire resources is essential to both reproduction and survival, changes in behaviours that maximise resource acquisition, should be under selection. Read More

Nature-based solutions efficiency evaluation against natural hazards: Modelling methods, advantages and limitations.

Sci Total Environ 2021 Aug 15;784:147058. Epub 2021 Apr 15.

Institute for Interdisciplinary Mountain Research, Austrian Academy of Sciences, Innsbruck, Austria.

Nature-based solutions (NBS) for hydro-meteorological risks (HMRs) reduction and management are becoming increasingly popular, but challenges such as the lack of well-recognised standard methodologies to evaluate their performance and upscale their implementation remain. We systematically evaluate the current state-of-the art on the models and tools that are utilised for the optimum allocation, design and efficiency evaluation of NBS for five HMRs (flooding, droughts, heatwaves, landslides, and storm surges and coastal erosion). We found that methods to assess the complex issue of NBS efficiency and cost-benefits analysis are still in the development stage and they have only been implemented through the methodologies developed for other purposes such as fluid dynamics models in micro and catchment scale contexts.

Development of a non-invasive method for monitoring variations in salt concentrations of seawater using nuclear technique and Monte Carlo simulation.

Appl Radiat Isot 2021 Aug 20;174:109784. Epub 2021 May 20.

Nuclear Engineering Institute - IEN/CNEN, Hélio de Almeida Street, Number 75, Rio de Janeiro, RJ, 21941-906, Brazil.

In the oil production industry, water is used as a fluid injected into the well to raise the oil when the well is depressurized. Water thus produced presents variations in the concentrations of dissolved salts, as there is a mixture of different types of water, related to its origin (such as connate water, sea water). Because it is reused in oil production, water needs to be monitored to maintain the standard suitable for its use as it can be hypersaline, contributing to the encrustation of pipes and contamination of underground water reservoirs.

Environ Pollut 2021 May 19;286:117400. Epub 2021 May 19.

State Key Laboratory of Water Environment Simulation, School of Environment, Beijing Normal University, Beijing, 100875, China.

Coastal wetland soils serve as a great C sink or source, which highly depends on soil carbon flux affected by complex hydrology in relation to salinity. We conducted a field experiment to investigate soil respiration of three coastal wetlands with different land covers (BL: bare land; SS: Suaeda salsa; PL: Phragmites australis) from May to October in 2012 and 2013 under three groundwater tables (deeper, medium, and shallower water tables) in the Yellow River Delta of China, and to characterize the spatial and temporal changes and the primary environmental drivers of soil respiration in coastal wetlands. Our results showed that the elevated groundwater table decreased soil CO emissions, and the soil respiration rates at each groundwater table exhibited seasonal and diurnal dynamics, where significant differences were observed among coastal wetlands with different groundwater tables (p < 0.

Cation-Driven Lipopolysaccharide Morphological Changes Impact Heterogeneous Reactions of Nitric Acid with Sea Spray Aerosol Particles.

J Phys Chem Lett 2021 May 22;12(20):5023-5029. Epub 2021 May 22.

Scripps Institution of Oceanography, University of California San Diego, La Jolla, California 92037, United States.

Lipopolysaccharides (LPS) in sea spray aerosol (SSA) particles have recently been shown to undergo heterogeneous reactions with HNO in the atmosphere. Here, we integrate theory and experiment to further investigate how the most abundant sea salt cations, Na, Mg, and Ca, impact HNO reactions with LPS-containing SSA particles. Aerosol reaction flow tube studies show that heterogeneous reactions of SSA particles with divalent cation (Mg and Ca) and LPS signatures were less reactive with HNO than those dominated by monovalent cations (Na).

Coastal resilience surges as living shorelines reduce lateral erosion of salt marshes.

Integr Environ Assess Manag 2021 May 14. Epub 2021 May 14.

Department of Environmental Sciences, University of North Carolina Wilmington, Wilmington, North Carolina, USA.

A growing suite of research has demonstrated that nature-based shoreline stabilization methods can increase resilience of coastal ecosystems by improving their capacity to return to predisturbance states. Previous work suggests that during hurricanes, living shorelines promote vertical accretion and experience less damage than traditional shoreline stabilization alternatives. Nevertheless, there is limited research looking at the impacts of major storm events on living shorelines and most studies have investigated a small number of sites. Read More

Sources of PM-bound water soluble ions at EMEP's Auchencorth Moss (UK) supersite revealed by 3D-Concentration Weighted Trajectory (CWT) model.

Chemosphere 2021 Jul 15;274:129979. Epub 2021 Feb 15.

UK Centre for Ecology & Hydrology, Bush Estate, Penicuik, UK.

The Concentration Weighted Trajectory (CWT) model is a well-known tool which combines the residence time (trajectory points) of air masses over specific regions with ambient concentrations of air pollutants, aiming to identify potential long range transport impacts. An upgraded 3D-version of CWT model (3D-CWT), investigating not only the geographical origin of the exogenous emissions but also the altitudinal layers in which the transport occurs, was developed and coupled with PM-bound concentrations of water soluble ions (nss- SO (non-sea salt sulfates), NO, Cl, NH, Na, Mg, Ca and K) for the years 2017-2018, derived by the Auchencorth Moss supersite in Southeast Scotland, United Kingdom (UK). The 3D-CWT model was implemented in two distinct altitudinal layers above ground level (0 m ≤ Layer 1 < 1000 m, 1000 m ≤ Layer 2 < 2000 m), because few trajectory points exceeded the 2000 m limit.
