Item type:Publication, Local social-ecological context explains seasonal rural-rural migration of the poorest in south-west Bangladesh(Public Library of Science, 2024-03-01)Bangladesh is one of the countries most affected by climate change. Internal migration is often presented as a response to environmental degradation. Here, using a people-centred perspective, we explore the complexity of the links between climate-induced change, environmental degradation caused by waterlogging and seasonal rural migration. We used an inductive qualitative approach in social sciences, conducting fourteen semi-directed interviews and six focus group discussions in March-April 2022. We related those results to a rainfall analysis on CHIRPS data for 1981-2021and we represented interactions and feedback between changes and livelihoods in a model. A complex picture of the situation is emerging, showing the interweaving effects of non-climatic and climatic changes, their interplay at different scales, their cumulative effects, the interactions between livelihood types and feedback between social and natural systems. Most of the climate-induced changes gradually become noticeable over the past 25 years. Climate data confirm these changes in recent decades, with July being wetter and January being dryer. Villagers reported waterlogging as the most significant change in their community, pointing to its multiple causes, originating in non-local and local, non-climatic anthropic changes, exacerbated by shrimp farm enclosures and worsened by climate-induced changes such as heavier rains, wetter monsoons and cyclones. Tiger prawn farms, reported as a lucrative and local adaptation to waterlogging and salinisation for the ones who can afford it, worsen the situation for the less wealthy, causing waterlogging and salinisation of the adjacent agricultural lands and buildings, the disappearance of traditional fishing and a reduction of the local job market. In addition, erratic rain patterns, droughts and cyclones affect local production and labour markets. COVID-19 lockdowns, by impacting markets and mobilities, further aggravated the situation. Inequality has increased as the range of adaptations of the less wealthy appears limited in this context of multiple crises. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Hallucinogenic mushrooms (Psilocybe, Hymenogastraceae) in the evolutive development of man's consciousness(Fundacion Miguel Lillo, 2024-05-01)This literature review explores the role of hallucinogenic fungi, specifically the Psilocybe genus of the Hymenogastraceae family, in the evolutionary development of human consciousness. Through a multidisciplinary approach spanning biology, ethnobotany, and neuroscience, the influence of compounds such as psilocybin and psilocin on consumers is examined, revealing their potential to trigger significant neurological and psychological effects. The impact on human consciousness is explored, highlighting perceptual, cognitive, and emotional changes. The evolutionary and anthropological development of humans is analyzed, investigating how the availability of food, the use of mushroom containing psilocybin, and physiological adaptations may have influenced reproductive success and survival over time. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Highly Pathogenic Avian Influenza A (H5N1) in Marine Mammals and Seabirds in Peru(Nature Research, 2023-12-01)Highly pathogenic avian influenza (HPAI) A/H5N1 viruses (lineage 2.3.4.4b) are rapidly invading the Americas, threatening wildlife, poultry, and potentially evolving into the next global pandemic. In November 2022 HPAI arrived in Peru, triggering massive pelican and sea lion die-offs. We report genomic characterization of HPAI/H5N1 in five species of marine mammals and seabirds (dolphins, sea lions, sanderlings, pelicans and cormorants). Peruvian viruses belong to lineage 2.3.4.4b, but they are 4:4 reassortants where 4 genomic segments (PA, HA, NA and MP) position within the Eurasian lineage that initially entered North America from Eurasia, while the other 4 genomic segments (PB2, PB1, NP and NS) position within the American lineage (clade C) that circulated in North America. These viruses are rapidly accruing mutations, including mutations of concern, that warrant further examination and highlight an urgent need for active local surveillance to manage outbreaks and limit spillover into other species, including humans. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Incorporating river morphodynamics in the characterization of key ecological system units for conservation in the western Amazon(Nature Portfolio, 2026-12-01)This study presents a novel methodology for developing a conservation Blueprint in the western Amazon, focusing on the Marañón, Napo, and Ucayali basins. Our approach highlights the critical role of fluvial integrity in shaping ecological functions and biodiversity through floodplain reshaping, habitat interconnecting across forests, and the transport and distribution of sediments, nutrients, and minerals throughout the region. We introduced two ecological attributes, the Modern Morphodynamics Index (MOR) and the Suspended Sediment Index (SSI), which together provide an improved representation of the temporal dynamics and connectivity that rivers impart to the landscape, as well as their influence on biotic dynamics. Our methodology integrates quantification and classification of biotic (five taxa) and abiotic variables across spatially nested hierarchies to assess ecological conditions and human-induced pressure. The resulting Ecological System (ES) units prioritizes areas with high ecological condition scores (i.e., high integrity) and low anthropogenic impact, enabling the development of more targeted conservation strategies. Our findings underscore (1) the value of incorporating MOR and SSI, which identify regions characterized by high dynamism and substantial sediment and nutrient loads as major drivers of biotic patterns; and (2) the urgent need for expanded species diversity surveys to better understand spatiotemporal distribution patterns across these complex river systems. Overall, this comprehensive framework offers a robust foundation for informing conservation planning and infrastructure development, supporting the long-term sustainable management of these critical Amazonian ecosystems.2
