Abstract:
... The values used for natural mortality (M) are very influential in stock assessment models, affecting model outcomes and management advice. Natural mortality is one of the most difficult demographic parameters to estimate, and there is often limited information about the true levels. Here, we summarise the evidence used to estimate natural mortality at age for the four main stocks of yellowfin tuna ...

Abstract:
... Empirical studies that investigate the effect of design thinking within complex contexts involving multiple stakeholders are rare. The aim of this study is to contribute to the literature on design thinking, by investigating the perceived usefulness of including design thinking activities into a complex research project for food safety. A survey was distributed to all participants in SafeConsume, ...
... More scientifically based stock assessments of data-limited species are rapidly increasing worldwide. Concurrently, non-negligible biases of stock status estimated using data-limited methods are becoming an issue. It is well known that the assumed prior distribution on depletion for some data-limited methods strongly affects the estimated stock status. Priors on depletion are best set based on exp ...

Abstract:
... Artificial reef designs have evolved rapidly over the past two decades, but further work is needed to inform how specific design features affect reef function. In south-eastern Australia, most artificial reefs consist of either a field of concrete modules, or large steel structures which are deployed to enhance recreational fisheries. To evaluate how these two designs might influence the densities ...

Abstract:
... This manuscript describes the natural soil amendments used in agriculture, which are divided into three groups: organic, organic-mineral, and mineral amendments. It also describes less popular agents, such as clay minerals, sewage sludge, and amendments based on slaughterhouse wastes. A specific group of organic amendments are algae-base amendments which are becoming more and more popular. The soi ...

Abstract:
... In this work, Chloroquine diphosphate, and the cationic dye Safranin-O were selectively removed from water using the agar-graphene oxide (A-GO) hydrogel, produced via simple one-step jellification process. The morphology of the A-GO biocomposite was characterized and batch experiments were performed, with adsorption isotherms satisfactorily fitting (R² > 0.98) Sips (Safranin-O) and Freundlich (Chl ...

Abstract:
... Natural mortality (M) is one of the most influential parameters in fisheries stock assessment and management. It relates directly to stock productivity and reference points used for fisheries management advice. Unfortunately, M is also very difficult to estimate, and hence very uncertain. Representing the uncertainty in M and how this influences estimates of management quantities is therefore an i ...

Abstract:
... As an important modeling method for multi-energy systems, the energy hub (EH) plays an important role in the planning and operation research of multi-energy systems. In this regard, this paper proposes an optimal load dispatch model for the EH system by considering the coupling relationship of electric and thermal energy. The target of the proposed model is to reduce the total cost of the EH syste ...

Abstract:
... Soil structure plays a central role in many soil processes that are environmentally relevant. Intermittent freezing of the soil over winter is an important abiotic disturbance in temperate climates and its effects on soil structure depend on the soil’s preexistent structural strength and cohesion. Management choices such as tillage and plant cover after harvest strongly influence soil structure, a ...

Abstract:
... The characterization of lake hydromorphology is crucial to understand the dynamics of biodiversity. In Europe, it is also a regulatory requirement of the Water Framework Directive. However, according to the literature, few methods include this characterization. The aim of this study is to review the state of the art of the methods currently used or under development in European countries to assess ...

Abstract:
... Previously, we found increased rates of ST-elevation myocardial infarction (STEMI) associated with increased ultrafine particle (UFP; <100 nm) concentrations in the previous few hours in Rochester, New York. Relative rates were higher after air quality policies and a recession reduced pollutant concentrations (2014–2016 versus 2005–2013), suggesting PM composition had changed and the same PM mass ...

Abstract:
... Iron oxide nanoparticles (IONPs) have been widely used as a nanoscale tool in biomedical research. However, it remains largely unknown how IONPs are transformed at a subcellular level to elicit distinct biological effects. In the present study, we prepared three different IONPs, including two IONPs targeting mitochondria (IONP-TPP) and lysosomes (IONP-APM), respectively, and a control with no spec ...

Abstract:
... Temperature can be considered as pro-oxidant factor that favor the generation of ROS on the species with lower antioxidant efficiency may leads to affect the level of tolerance. So the basic antioxidant enzyme activity (LPO, CAT, SOD, GPx and GST) of gastropod Nerita oryzarum was evaluated at six stations which located between the thermal effluent discharges points from Tarapur Atomic Power Statio ...

Abstract:
... In this work, we successfully constructed a label-free electrochemiluminescence (ECL) immunosensor for the detection of breast cancer marker antigen (CA15-3). In particular, 3,4,9,10-perylenetetracarboxylic acid (PTCA) is cleverly attached to the surface of silica spheres as a luminophore (NH₂-SiO₂-PTCA), which greatly alleviates the disadvantage of PTCA anti-induced aggregated luminescence and im ...

Abstract:
... Mercapto-palygorskite (MP) is a novel immobilization material for cadmium (Cd) pollution, but the immobilization mechanism on alkaline Cd contaminated soil is not completely clear. In this paper, field experiment was carried out to study the effect of MP on the transfer of Cd in aggregates at different depth, the contribution of soil aggregates to the reduction of Cd in bulk soil and the immobiliz ...

Reducing the possibility of a potential phosphorus (P) resource crisis and increasing P use efficiency (PUE) by improving P fertilizer management is of paramount importance for truly sustainable agricultural production. However, information on how layered application of phosphate fertilizer at different soil depths affects yield and PUE in winter wheat (Triticum aestivum L.) is limited. Here, a 2- ...

Abstract:
... Abundant reserves of metals and oil have spurred large-scale mining developments across northwestern Canada during the past 80 years. Historically, the associated emissions footprint of hazardous metal(loid)s has been difficult to identify, in part, because monitoring records are too short and sparse to have characterized their natural concentrations before mining began. Stratigraphic analysis of ...

Abstract:
... Understanding the spatial and temporal habitat use of a population is a necessary step for recovery planning. For Chinook salmon (Oncorhynchus tshawytscha), variation in their migration and habitat use complicate predicting how restoring habitats could impact total recruitment. To evaluate how juvenile life history variation affects a population’s response to potential restoration, we developed a ...
