Biochar amendment for reducing the environmental impacts of reclaimed polluted sediments

Journal of Environmental Management, Journal Year: 2023, Volume and Issue: 344, P. 118623 - 118623

Dredging activities produce large amounts of polluted sediments that require adequate management strategies. Sediment reuse and relocation can involve several environmental issues, such as the release CO2 nitrogen compounds in environment, transfer metals to plant tissues persistence phytotoxic compounds. In this framework, aim present work is evaluate use biochar at different doses, combination with growth, reduce impacts dredged sediments. Irrespective treatment, amendment sediment lowest dose (3%) reduced by 25% emissions substrate, 89% substrate carbon loss 35% amount released into environment (average values three treatments). The negative priming effect on organic matter mineralization be responsible for beneficial reduction environment. lack similar effects observed higher doses depend low albedo particles, causing warming (+1 °C highest dose) accelerating mineralization. Finally, shrub growth 3% was able offset emission lost. This provides new insight potential benefit related matter-rich sediments, suggesting moderate wood plantation

On the structure of species-function participation in multilayer ecological networks

Nature Communications, Journal Year: 2024, Volume and Issue: 15(1)

Understanding how biotic interactions shape ecosystems and impact their functioning, resilience biodiversity has been a sustained research priority in ecology. Yet, traditional assessments of ecological complexity typically focus on species-species that mediate particular function (e.g., pollination), overlooking both the synergistic effect multiple functions might develop as well resulting species-function participation patterns emerge harbor functions. Here we propose mathematical framework integrates various types observed between different species. Its application to recently collected data an islet ecosystem-reporting 1537 691 plants, animals fungi across six (pollination, herbivory, seed dispersal, decomposition, nutrient uptake, fungal pathogenicity)-unveils non-random, nested structure way plant species participate The further allows us identify ranking functions, where woody shrubs decomposition keystone actors whose removal have larger-than-random secondary extinctions. dual insight-from functional perspectives-offered by opens door richer quantification ecosystem better calibrate influence multifunctionality functioning biodiversity.
