Guidance on integrating marine environmental impacts of ocean alkalinity enhancement into life cycle assessmentNARA Subscribed
Purpose Ocean alkalinity enhancement (OAE) is considered a promising marine carbon dioxide removal (mCDR) option and may contribute to climate change mitigation. Life cycle assessment (LCA) is used to assess OAE environmentally but faces limitations in capturing marine impacts. Improving the assessment of OAE in LCA requires a detailed understanding of its marine environment impact pathways to develop sub-compartmentalised and...
An open-source regionalization approach for subnational EEMRIO insights and proof-of-concept application to EU steel circularityNARA Subscribed
Environmentally extended multi-regional input–output (EEMRIO) analysis provides a robust methodology for assessing economic, social, and environmental footprints across nations and regions. Increasing its geographical resolution is essential for addressing local environmental issues and informing targeted policy decisions. While subnational EEMRIOs ideally rely on survey data, such data are often unavailable or resource-intens...
Lifting the lid on Marine HeatwavesNARA Subscribed
Deep‐sea lobster shifts in distribution and population connectivity under future climate changeNARA Subscribed
New Zealand scampi ( Metanephrops challengeri ) is an economically important deep‐sea lobster species found between 140 and 640 m on New Zealand’s continental shelf and slopes. Adult scampi are sedentary and population connectivity is mediated by larval dispersion. In this study we use high‐resolution regional marine climate down‐scalings to examine how climate change will impact connectivity and population distribution in med...
Marine heatwaves (MHWs) are increasing in frequency and intensity globally, yet the impacts of such extreme events are not well understood. We review the effects of MHWs on the fisheries and ecosystems of Aotearoa‐New Zealand (NZ), an island nation with over 15,000 km of coastline, and 4 million km 2 of exclusive economic zone, that supports diverse marine communities and valuable commercial and recreational fisheries. Using A...
Aotearoa New Zealand’s marine carbon cycle in a changing climate – Current understanding and future directionsNARA Subscribed
The marine system plays a critical role in the global climate cycle, as a major control of atmospheric carbon dioxide (CO 2 ). Marine primary production (photosynthesis) and remineralisation of organic carbon (respiration, degradation) determine the amount of CO 2 sequestered in marine sediments and deep‐water environments on century to millennial timescales. The stocks and fluxes of the marine carbon cycle are susceptible to...
Differentiation grade is highly concordant between matched primary and metastatic colorectal cancerNARA Subscribed
Differentiation grade of colorectal cancers (CRC) is histologically defined by the proportion of the tumour which retains the glandular architecture of the normal colon. Poorly differentiated CRCs display loss of glandular architecture and canonical markers of colonic differentiation and are associated with increased metastatic capacity and poorer prognosis. It is currently unclear whether poorly differentiated cells within a...
Non-indigenous species (NIS) are on a rise globally. They can pose strong impacts on ecosystems in their non-native range and can therefore be a serious threat to biodiversity. Here, we compile the existing information available regarding the extent to which commercially and recreationally used fish stocks (exploited fish species) are affected by NIS. To do so, we conducted a literature review to summarize the known and presum...
As global surface temperatures have increased with human‐induced climate change, notable compound climate extremes in the New Zealand (NZ) region associated with atmospheric heatwaves (AHWs) and marine heatwaves (MHWs) have occurred in the past 6 years. Natural modes of variability that also played a key role regionally include the Interdecadal Pacific Oscillation (IPO), El Niño/Southern Oscillation (ENSO) and changes in the l...
Cluster analysis of long COVID symptoms for deciphering a syndrome and its long-term consequenceNARA Subscribed
The long-term symptoms of COVID-19 are the subject of public and scientific discussions. Understanding how those long COVID symptoms co-occur in clusters of syndromes may indicate the pathogenic mechanisms of long COVID. Our study objective was to cluster the different long COVID symptoms. We included persons who had a COVID-19 and assessed long-term symptoms (at least 4 weeks after first symptoms). Hierarchical clustering was...
A facile Agrobacterium-mediated transformation method for the model unicellular green algae Chlamydomonas reinhardtiiNARA Subscribed
A reliable and simple Agrobacterium -mediated transformation system for the unicellular green algae model organism Chlamydomonas reinhardtii has been developed. The protocol has been successfully employed with both neomycin phosphotransferase II ( nptII ) and the phleomycin resistance ( bleI ) genes coupled with the selective agents paromomycin and zeocin, respectively. A set of binary vectors were assembled that carry the sel...
Machine Learning–Based Identification of Target Groups for Thrombectomy in Acute StrokeNARA Subscribed
Whether endovascular thrombectomy (EVT) improves functional outcome in patients with large-vessel occlusion (LVO) stroke that do not comply with inclusion criteria of randomized controlled trials (RCTs) but that are considered for EVT in clinical practice is uncertain. We aimed to systematically identify patients with LVO stroke underrepresented in RCTs who might benefit from EVT. Following the premises that (i) patients witho...
Species invasions often occur on coasts and estuaries where abiotic conditions vary, e.g. salinity, temperature, runoff etc. Successful establishment and dispersal of non-indigenous species in many such systems are poorly understood, partially since the species tend to show genetic and ecological plasticity at population level towards many abiotic conditions, including salinity tolerance. Plasticity may be driven by shifting e...
