Unprecedented Burning in Tropical Peatlands During the 20th Century Compared to the Previous Two MillenniaNARA Subscribed
Tropical peatland wildfire incidence has risen in recent decades, driven by drainage for land use and intensified by severe droughts with global climate change. These disturbances have altered vegetation structure, disrupted ecosystem functioning, and increased carbon emissions, particularly in Southeast Asia. However, the long‐term history and characteristics of wildfires in tropical peatlands remain largely unknown. Here, we...
Evidence-based decision making as part of marine spatial planning (MSP) requires an understanding of marine ecosystem structure and functioning, including associated spatial-temporal variability. Community spatial structure, such as that derived from larval transport dynamics, should be considered in decision making because it can govern system stability and resilience to perturbation. We utilize a novel network-theoretic appr...
Welfare Indicators for Aquaculture Research: Toolboxes for Five Farmed European Fish SpeciesNARA Subscribed
Refining approaches to measuring, monitoring and appraising animal welfare in aquaculture research is key to (i) protecting and optimizing it, (ii) documenting the severity of how and when it deviates, and (iii) ensuring good scientific quality, reliable results and reproducibility, amongst other factors. However, different fish species and life stages can have varying welfare needs and assessing their welfare can be challengi...
Drill core samples from the Profitis Ilias Pb-Zn-Cu-Ag-Au vein mineralization on Milos Island, Greece provide new insights into (i) the metal sources, (ii) the primary vertical metal(loid) distribution, and (iii) the supergene enrichment processes in a transitional shallow-marine to subaerial hydrothermal environment. Metal contents of unaltered and altered host rocks combined with Pb isotope analyses of hydrothermal sulfides...
Tidal stream energy is a renewable energy resource that might be developed to offset carbon emissions. A tidal energy demonstration (TED) area has been designated in Minas Passage, Bay of Fundy, for testing and installing marine hydrokinetic (MHK) turbines. Regulations require quantification of the potential for MHK turbine installations to harm local populations of marine animals. Here, we use acoustic telemetry to quantify t...
Per- and polyfluoroalkyl substances (PFASs) are omnipresent and have been shown to induce a wide range of adverse effects, including hepatotoxicity, developmental toxicity and immunotoxicity. So far, little information is available about the mechanisms underlying the toxicity of PFASs, including those related to their immunotoxicity. Reported immunotoxic effects of PFASs include decreased antibody responses in experimental ani...
Small Block Model Tests for the Behaviour of a Blocky Rock Mass Under a Concentrated Rock Anchor LoadNARA Subscribed
Rock anchors are used to stabilise large-scale infrastructure such as the foundations of high buildings or road cuts, and their failure could lead to severe economic and social consequences. A rock anchor can fail in one or more of the following four modes; breakage of the tendon steel, tendon-grout bond failure, grout-rock bond failure and rock mass failure. In current rock anchor design, the knowledge for the first two failu...
Urinary calculi are observed in some cultured marine fish larvae and may negatively impact larval health and survival. This study assessed urinary calculi in striped trumpeter Latris lineata larvae from hatching to 28 days post‐hatching (dph). The prevalence of urinary calculi was variable over time and ranged from 15% to 50%, whereas the average size of calculi increased with larval age. Urinary calculi were semi‐translucent,...
The high-K calc-alkaline to shoshonitic volcanism of Limnos, Greece: implications for the geodynamic evolution of the northern AegeanNARA Subscribed
Genetic models for the formation of K-rich magmas in subduction-related settings range from partial melting of subduction-affected mantle sources to melting of crustal rocks depending on the local tectonic framework. The Miocene high-K calc-alkaline to shoshonitic rocks of Limnos Island reflect the magmatic activity in the northern Aegean, which migrated southwards in response to trench retreat and the collision of continental...
Seasonal changes in stress metabolites of native and introduced red algae in New ZealandNARA Subscribed
Intertidal algae have to cope with diurnally and seasonally fluctuating environmental factors such as salinity, temperature, dehydration, and light. In New Zealand, solar radiation, including the ultraviolet wavelengths, is also an important stress factor for such algae. Therefore, two native ( Bostrychia arbuscula W.H.Harvey [Ceramiales], Champia novae-zelandiae (J.D.Hooker & Harvey) Harvey [Rhodymeniales]) and one introduced...
