- Modeling the distribution of invasive species in small islands under future climatesPublication . Cabral, V.; Matos, A. A.; Borges, Paulo A. V.; Borda-de-Água, L.; Azevedo, E. B.ABSTRACT: The project described in the article aims to develop a robust data preparation and modeling pipeline to predict the habitat suitability of invasive species in the Azores Archipelago under current and future climate scenarios. Initial findings suggest that ensemble modeling is a useful tool for reducing uncertainty, and also the prospect for a more automated predictor selection. We performed test cases for two species: Gunnera tinctoria (Molina) Mirb. and Paspalum vaginatum (Sw.) P.Fourn. In this summary, we will present our results for Paspalum vaginatum.
- Laurus Azorica Leaves : Sesquiterpene Lactones and Antiaging ActivityPublication . Viveiros, Mariana Moniz; Barreto, Maria do Carmo; Seca, Ana M. L.Plants are a relevant source of biologically active compounds for skin protection. Laurus azorica (Seub.) Franco, an endemic species from Azores, was traditionally used as a disinfectant, and the oil from its berries was used to treat wounds. This species is barely studied concerning its chemical constituents and biological activities. In this study, three sesquiterpene lactones, costunolide, 11,13-dehydrosantonin and reynosin, were isolated for the first time on the hexane fraction of the ethanol extract from Laurus azorica leaves by chromatographic techniques.

- Valorization of Macaronesia Beach-Cast Seaweeds : Secondary Metabolites and Antiaging ActivityPublication . Seca, Ana M. L.; Faustino, Luís M. M.; Viveiros, Mariana Moniz; Rosa, Gonçalo P.; Barreto, Maria do CarmoBeach-cast seaweeds are a seasonal phenomenon consisting of the accumulation of large tons of algae on beaches, which is unpleasant for beach users and affects the tourism industry, mainly because tourists often interpret stranded natural litter as lowering beach quality, especially if the material starts to decompose. These beach casts are always variable mixtures of different species of seagrass and seaweeds. The present work aimed to contribute to the valorisation of this biomass by studying its chemical composition and bioactivities that reveal its potential in the pharmaceutical and/or cosmeceutical industries.

- Kaempferol Derivatives from Hedychium gardnerianum : Unveiling the Potential of an Invasive PlantPublication . Tavares, Wilson R.; Barreto, Maria do Carmo; Seca, Ana M. L.The therapeutic properties of plants and of their secondary metabolites are a current research topic of great interest. Considering that Hedychium species are used in folk medicine around the globe, Hedychium gardnerianum Sheppard ex Ker Gawl., an extremely aggressive invasive plant in Hawaii and in Azores, was selected and phytochemically studied in order to search for natural compounds with interesting biological activities.

- Cosmeceutical Potential of the Green Macroalga Caulerpa ProliferaPublication . Rosa, Gonçalo P.; Seca, Ana M. L.; Barreto, Maria do Carmo; Pinto, Diana C. G. A.The present cosmeceutical industry has been gradually shifting its interest from products based on synthetic compounds to macroalgae-based products due to their interesting antiaging properties but also to their lower cytotoxicity and allergens content. Molecules isolated from macroalgae already showed potential as either active cosmetic ingredients or key elements for the consistency of the cosmetic formulation. In this regard, it is of foremost importance to keep studying the chemical composition of different algal species, aiming to find new compounds with cosmeceutical potential. […].
- Marine and coastal ecosystems and climate change : a public awareness surveyPublication . Fonseca, Catarina; Andriamahefazafy, Mialy; Casal, Gema; Chaigneau, Tomas; Cornet, Cindy C.; Degia, Anna; Failler, Pierre; Ferraro, Gianluca; Furlan, Elisa; Hawkins, Julie P.; de Juan, Silvia; Krause, Torsten; Pérez, Géraldine; Roberts, Callum M.; Tregarot, Ewan; Wood, Louisa; O'Leary, Bethan C.Hundreds of millions of people worldwide directly rely on marine and coastal ecosystems for their food, livelihoods and ways of life, yet these ecosystems are subject to a variety of pressures (UNEP, 2006; Hoegh-Guldberg et al., 2015; Korpinen et al., 2019). These pressures include climate change - one of the most urgent challenges societies are currently facing, with “long-lasting or irreversible” adverse consequences predicted as a result (IPCC 2018). Healthy marine and coastal ecosystems are a pre-requisite for the continuing delivery of ecosystem services, such as the provision of food, climate regulation and carbon storage. Therefore, it is critical to achieve a more sustainable management and effective protection of such valuable ecosystems. Policy makers are increasingly aware of the adverse effects of climate change and environmental degradation on our coasts and oceans. As public opinion influence decision-making on the actions to take and contribute to the success of their implementation (Rasmussen et al., 2017), it is important to understand how well informed the public is about climate change impacts and solutions in marine and coastal systems. In recent years, significant efforts have been made by the scientific community to raise public awareness of climate change and the links between healthy marine and coastal ecosystems and ecosystem service provision, including their role in mitigating and adapting to climate change (Barracosa et al., 2019). However, there has been little consideration of how the public perceives the interlinkages between climate change and its effects on marine and coastal ecosystems. Instead, most efforts have addressed climate change perceptions (van Valkengoed et al., 2022) Mildenberger et al., 2019) and marine threats perceptions (Ankamah-Yeboah et al., 2020; Lotze et al., 2018), separately. In the scope of the research project on “Marine Coastal ecosystems Biodiversity and Services in a changing world” (MaCoBioS) funded by the European Commission, people’s views on climate change, the value of marine and coastal ecosystems and the threats facing they face, as well as potential management options were investigated.
- Evaluating the effectiveness of nature-based solutions to climate change adaptation : A literature review of existing frameworks and indicatorsPublication . Halim, Firdaous; Fonseca, Catarina; O'Leary, Bethan C.; Villasante, SebastiánClimate change is generating a broad range of negative impacts worldwide, particularly on marine and coastal ecosystems (MCE) (IPCC-SROCC, 2019 and IPBES-IPCC, 2021). These impacts include coastal flooding and erosion, sea-level rise and storm surges. To adapt to these adverse effects and improve the well-being of coastal communities, engineered approaches have traditionally been used; however, there is growing recognition of the potential of Nature-based Solutions (NbS) to address these impacts while enhancing biodiversity (Baustian et al., 2020 and Chausson et al., 2020). NbS are actions that aim to address societal challenges and provide socialecological benefits by harnessing ecological processes (Cohen-Shacham et al., 2016). They have the potential to support climate change adaptation, for example, through storm surge attenuation, wave height reduction and flood protection; thus, enhancing ecosystem resilience and the provision of ecosystem services (i.e., improved fish stocks, biodiversity conservation, coastal tourism and recreation) (Chausson et al., 2020; Seddon et al., 2020; UNEP, 2021).

- Nature exposure scale : Psychometric properties, reliability and validity evidence from Azores (Portugal)Publication . Arroz, Ana Moura; Picanço, Ana; Silva, Alexandra R.; Rosário, Isabel Amorim do; Gabriel, RosalinaAlthough exposure to nature has asserted its impact on health and well-being in numerous studies, the way in which it is assessed is still problematic and there are no validated measures for Portuguese-speaking countries. Hence, in this study, we carried out a psychometric analysis of the Nature Exposure Scale (NES), a self-report instrument with four Likert items, from its administration to a convenience sample of 579 adults residing in the Azores (Portugal). Overall, the results of the NES scale show good reliability and adequate divergent and convergent validity. But the understanding of its latent structure must be deepened.
- Ask a Scientist : using place-based mobile learning to promote adolescents’ interest in naturePublication . Silva, Alexandra R.; Gabriel, Rosalina; Arroz, Ana Moura; Sousa, Daniel; Piasentin, Flora Bonazzi; Rosário, Isabel Amorim do; Matos, SóniaQuestioning can be an important instrument to promote students' interest in nature. In this study, based on questions from local adolescents about nature, we designed mobile learning materials focused on local nature-rich environments in the form of podcast episodes and tested them, in a quasi-experimental design, with a new group of adolescents to assess their efficacy in promoting participants’ curiosity about nature. Contributions of this study include insights for future research on technological nature and adolescents' interaction with nature and educational developments related to place-based learning for nature conservation.
- The Field Guide app : Connecting island communities to local conservation through mobile interactionPublication . Sousa, Daniel; Rocha Silva, Alexandra Filipa; Rosário, Isabel Amorim do; Ashby, Simone; Arroz, Ana Moura; Piasentin, Flora Bonazzi; Gabriel, Rosalina; Matos, SóniaHere we present Field Guide, a mobile application (app) designed to connect communities to nature-rich environments, which play a crucial role in nature conservation efforts. The app aligns to a mode of science communication that seeks to establish direct contact between publics and specialised scientific communities, most commonly known as the ’ask a scientist’ approach. Field Guide uses a geolocation positioning system to offer users the opportunity to pose questions to scientists whilst exploring a nature conservation site. In this demo, we display the app as a mock-up presentation before its first use by children and teenagers during afield-trip to a nature trail later in 2021.
