In recent decades, the invasive seaweed Rugulopteryx okamurae has had a huge environmental impact on marine biodiversity, fisheries, GHG emissions and public health along much of Iberian Peninsula islands coastline. Due to enormous amount algae biomass that is expelled beaches where it slowly rots, some circular economy business initiatives, such as composting, are emerging. present study, we compared quality compost obtained from earthworms ( Dendrobaena veneta ), cockroaches Eublaberus sp .), mealworms Tenebrio molitor ) black soldier fly larvae Hermetia illucens ). Batches fed with 100% organic kitchen waste (control group) were batches 50% (treatment group). Our results show most sensitive species D . T R toxins adequately.

Abstract Cellulose has been intensively investigated for biomedical applications, because of its excellent properties, like biodegradability, biocompatibility, abundant availability renewable resources and cost-effectiveness. Among all sources cellulose, marine macroalgae or seaweeds, are acquiring tremendous attention, due to their high around the world. Moreover, atypical proliferation some exotic species represents a serious problem ecosystems, since accumulation threatens native oceanic worldwide. Several studies already reported successfully extraction cellulose derivatives from brown, green red macroalgae. The extracted properties vary according type algae, maturity used methods. This review will cover main methods extract focusing on more sustainable ones, as well further processing into various derivatives. Electrospun nanofibers have revealed great potential such delivery therapeutic agents, tissue engineering, wound dressings enzyme immobilization. Pure presents drawbacks, limited solubility in organic solvents inability fuse inter intra-molecular hydrogen bonding. To overcome these limitations, derivatives, which includes microcrystalline nanocrystals, nanofibers, acetate carboxymethyl extensively studied generate electrospun fibers. Therefore, this aims explore seaweeds promising source methodologies compounds, demonstrate developed by electrospinning with algae-based applications.

Biological invasions, resulting from human activities, exert substantial impacts on ecosystems worldwide. This review focuses marine invasive alien species (IAS) in Europe, examining the current state, proposing strategies to address problem, and offering recommendations for enhanced management. Effective management of biological invasions relies accessible, accurate data inform decision-making. Information systems such as European Alien Species Network (EASIN), Aquatic Non-Indigenous Cryptogenic (AquaNIS), World Register Introduced Marine (WriMS) provide comprehensive databases IAS, but their sustainability requires long-term maintenance, continuous updates, support. Most countries lack specific monitoring programs standardization improvement methods are needed. Port plays a vital role early detection new arrivals, recent advancements molecular techniques show promise effective IAS monitoring. Risk screening tools commonly employed rank taxa based invasiveness potential regions, variations protocols can yield inconsistent results. impact assessments highlight resource competition, novel habitat creation, predation primary mechanisms negative biodiversity, while creation habitats represents key mechanism positive impacts. Preventing introductions is critical, measures ballast water treatment implemented reduce likelihood introductions. However, understanding introduction pathways remains uncertain many IAS. Eradication control efforts have limited success, emphasizing need biosecurity measures. Climate change, especially ocean warming, intensify native ecosystems. In climate change hotspots, some tropical aliens may, however, compensate loss thermally sensitive natives with similar traits. Therefore, it imperative consider interactions between developing conservation strategies. Enhancing Europe entails i) securing adequate funding, ii) expanding list Union Concern adequately cover iii) learning successful practices, iv) sustaining information systems, v) improving warning innovative technologies, vi) enhancing prediction models, vii) conducting integrated mapping cumulative impacts, considering benefits ecosystem functioning services.

In recent years, pelagic sargassum (S. fluitans and S. natans - henceforth sargassum) macroalgal blooms have become more frequent larger with higher biomass in the Tropical Atlantic region. They environmental socio-economic impacts, particularly on coastal ecosystems, tourism, fisheries aquaculture industries, public health. Despite these challenges, has potential to offer commercial opportunities blue economy, although, it is reliant key chemical physical characteristics of for specific use. this study, we aim utilise remotely sensed spectral profiles determine species/morphotypes at different decomposition stages their biochemical composition support monitoring valorisation sargassum. For this, undertook dedicated field campaigns Barbados Ghana collect, first time, situ measurements between 350 2500 nm using a Spectra Vista Corp (SVC) HR-1024i spectrometer stranded biomass. The were complemented by uncrewed aerial system surveys DJI Phantom 4 drone P4 multispectral instrument. Using ground airborne datasets research developed an operational framework remote detection beached sargassum; created maps infer composition. We able identify some regions, including consistent absorption feature (920-1080 nm) found all morphotype profiles; also observed distinction fresh recently around 900-1000 nm.

Human-induced pressures have led to substantial changes in marine ecosystems worldwide, with the introduction of non-indigenous species (NIS) emerging as a significant threat ecological, economic, and social aspects. The Macaronesian islands, comprising Azores, Madeira, Canary Islands, Cabo Verde archipelagos, are regions where regional economy is dependent on resources (e.g., traffic, ecotourism fisheries). Despite their importance, concerted efforts manage biological invasions Macaronesia been scarce. In this context, current study aims contribute much-needed debate biosecurity measures unique insular ecosystem prevent mitigate impact NIS. By adhering Preferred Reporting Items for Systematic Reviews Meta-Analyses (PRISMA) criteria, work validated analyzed 260 documents providing insights into management NIS until 2022.

Beach-cast seaweed of the invasive brown macroalga Rugulopteryx okamurae was used in this study as raw material to obtain fermentable sugars, which can be converted into high added-value products. The dietary fibre composition macroalgae determined and compared other red macroalgae, showing one highest proportions (27.3 %) cellulose (13.6 %). Therefore, enzymatic hydrolysis R. could lead obtaining hydrolysates with a concentration reducing sugars. main variables (biomass loading, enzyme dose stirring rates) operation mode (fed-batch versus batch) were evaluated maximize sugar concentration. Thus, maximum total 13.7 g/L obtained at optimum conditions: biomass loading 10 % (w/v), 50 FPU/g biomass, 250 rpm operating batch mode. In addition, kinetic model has been developed describe biomass. model, unlike first-order kinetics, includes specific term considering diffusion through solid proposed leads better fitting experimental data than especially for long incubation times.
