Summary: This paper explores the potential of studying wooden raw materials used during the Prehispanic period on the island of Gran Canaria through xylological analyses. The results suggest a preference for pinewood in crafting artefacts, with the presence of dragon tree wood in some funerary boards. The analysis also indicates a sophisticated woodworking knowledge in a region lacking metal ores. Further research on other islands of the archipelago is needed for a comprehensive understanding of wood procurement and use during this period.

Summary: Animal poisoning poses a significant threat to wildlife conservation, with a higher degree of threat observed in the Canary Islands, leading to the implementation of a legal framework to combat wildlife poisoning. The main agent used in the archipelago is Carbofuran, with a growing trend of using mixtures of pesticides in baits. Areas with lower population density and higher agricultural and livestock activity have a significantly higher positivity rate for poisoning.

Summary: This study in the Canary Islands reveals the relationship between specific characteristics and smoking behavior, including mental health factors. The results indicate a positive correlation between psychopathology and the probability of smoking. Public policies aimed at reducing the risk of mental illnesses may contribute to a decrease in smoking prevalence and the development of more effective prevention strategies.

Summary: This research focuses on evaluating the Water-Energy-Environment Nexus implications of replacing fossil-based power generation systems with wind and photovoltaic renewable energy systems in water-scarce regions. The results show that this replacement improves water sustainability and reduces CO2 emissions.

Summary: There is a concern about the health effects of pesticide residues in bananas and their link to chronic diseases. This study analyzed 733 banana samples produced in the Canary Islands from 2008 to 2017, investigating 191 different active substances and their toxicological, agricultural, and legal implications.

Summary: Consistent He-3/He-4 ratios have been measured in geothermal fluids and gases from Cumbre Vieja and Teide in the Canary Islands for over 25 years. The differences in helium isotopes between the two islands can be attributed to distinct mantle sources, with La Palma having a high-mu (HIMU)-type mantle source and Tenerife having a more enriched mantle. Temporal variability in He-3/He-4 distribution in geothermal samples compared to older lavas indicates heterogeneity and evolution of mantle sources at intraplate volcanoes.

Summary: Waves in coastal areas can be converted into electricity through wave energy converters. However, the lack of knowledge about the regional distribution and variability of wave properties is a challenge for wave energy conversion. In this study, we accurately simulated the wave climate of the Canary Islands using physics-based and non-physics-based approaches. The results showed that the annual mean wave power on the north-western coast of Lanzarote Island was about 25 kW/m. The variability of wave energy resource was relatively low, and the dominance of swell waves reduced the variability when combined with wind energy.

Summary: This study investigated the causal mechanism of the first mesopelagic fish strandings along the southeast shore of Gran Canaria Island. It was found that these strandings were mainly dominated by Diaphus dumerilli, but other Myctophidae species were also present. The study suggests that a monitoring program of coastal sites combined with satellite-derived environmental data can provide valuable information for modeling and predicting such events. The findings highlight the importance of mesoscale oceanographic structures in the occurrence of fish strandings.

Summary: Before the COVID-19 pandemic, the World Tourism Organization (UNWTO) emphasized the need for innovation, sustainability, and accessibility in sun and beach tourist destinations. This study focuses on the geotourism development in La Palma, an island in the Canary Islands, which has faced a tourism crisis exacerbated by the eruption of Tajogaite, Cumbre Vieja in 2021. The research identifies and characterizes points of interest in the two largest population centers, Santa Cruz de La Palma and Los Llanos de Aridane, showcasing the diverse natural and cultural volcanic and non-volcanic heritage of the regions.

Summary: Extreme geohazards like volcanic eruptions, earthquakes, landslides, and tsunamis can cause cascading effects with unpredictable risks, which are often overlooked in hazard assessment. Anticipating and preparing for such extreme events is crucial for maintaining safe and sustainable lifestyles. Volcanic islands, such as Tenerife in the Canary Archipelago, have experienced multiple occurrences of cascading extreme hazards in the past, highlighting the importance of understanding and mitigating the potential consequences.

Summary: This research examines the impact of the Cumbre Vieja volcano eruption on regional and local air quality using open-source data. The study focuses on emissions of volcanic material and the spread of aerosols in the atmosphere. The findings can help in forecasting air pollution and associated health risks resulting from large-scale volcanic eruptions.

Summary: In this study, the authors used paleogenomic data from the indigenous people of the Canary Islands to investigate the Prehistory of North Africa and how genetics were influenced by isolation and resource availability. They found that the native population of the Canary Islands showed genetic signatures related to Bronze Age expansions in Eurasia and trans-Saharan migrations, in addition to components already present in Moroccan Neolithic populations. The lack of gene flow between islands and constant or decreasing population sizes indicate isolation. The researchers also observed variations in genetic diversity among islands, with islands with fewer natural resources exhibiting greater effects of insularity and isolation. Lastly, there were consistent genetic differences between eastern and western islands, suggesting a more complex colonization process than previously thought.

Summary: The Canary Islands have experienced two volcanic eruptions in the last decade: a submarine eruption in El Hierro in 2011-12, and a subaerial eruption in La Palma in 2021. Necropsies of fish specimens from El Hierro and La Palma revealed pathological findings associated with both eruption styles. During the submarine eruption, high mortality and congestion in various organs were observed in fishes, while fishes near the lava deltas of the subaerial eruption showed increased mortality, ash particles in their gills, and intestinal impaction with volcanic material.

Summary: Climate change is expected to worsen weather conditions prone to wildfires in the Canary Islands. A regional climate projection study based on the CMIP5 initiative shows that by the end of the century, all fire risk indicators will increase, with the fire season potentially extending up to 75 days per year. The main parameter influencing the fire danger index is currently temperature, but the significance of precipitation will increase in the future.
