- 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.

- Macro biological degradation of wood treated with sorbitol and citric acid : first results from marine environment and termite exposurePublication . Treu, Andreas; Nunes, Lina; Larnøy, ErikMost European wood species are rapidly and severely degraded in termite-infested areas and the marine environment. There is a need for new solutions, especially in the marine environment, since we lack wood preservatives approved for marine applications in Europe. Several wood modification systems show high resistance against both marine borers and subterranean termites. However, the existing commercialised methods of wood modification are costly. Therefore, a new, low cost and non-toxic wood modification system from inexpensive and readily-available feedstock chemicals have been used in this study. The treatment of wood with a combination of sorbitol and citric acid (PS-modification) showed good resistance against wood borers in the marine environment after one season and against subterranean termites in the laboratory after eight weeks. Future results from the ongoing field tests in the marine environment will reveal the long-term performance of PS-treated wood. The low termite survival rate in the non-choice test already in the first week of testing indicate a mode of action which is not comparable with other wood modification treatments.
- Evaluation of ETICS characteristics that affect surface mould developmentPublication . Parracha, João Luís; Cortay, Armand; Borsoi, Giovanni; Veiga, Rosário; Nunes, LinaExternal Thermal Insulation Composite Systems (ETICS) are nowadays often used in new constructions but are also one of the most frequently used thermal retrofitting solutions for buildings. These systems have several advantages such as low installation cost, ease of application and increased thermal efficiency. Nevertheless, a number of questions have been raised on their long-time durability particularly related to biodeterioration. Biological growth is strongly influenced by several parameters, such as water content, temperature, pH but also by the type and hygroscopic properties of the building materials. It is therefore essential to understand and correlate those properties with biological growth. This paper aims at evaluating some ETICS characteristics that might influence surface mould development which is recognized as one of the major groups of deteriorating organisms. The susceptibility of the surface finishing layer and thermal insulation to biological growth was assessed through natural inocula and selected fungi and, whenever possible, correlated with water absorption and drying capacity. This study is part of a wider research project: WGB_Shield (Shielding building‘ facades on cities revitalization. Triple-resistance for water, graffiti and biocolonization of external thermal insulation systems) that aims at the development of ETICS with improved durability in the urban environment. Further development on this issue are ongoing.
- Hábitos alimentares de Paralonchurus brasiliensis (Steindachner, 1875) em Penha, SC, Sul do BrasilPublication . Goetten, Maurício Antônio; Bosse, Afonso; Sedrez, Mário C.; Barrilli, Germano H. C.; Verani, José R.; Martins, Mariana de Oliveira; Branco, Joaquim Olinto; Barreiros, João P.Paralonchurus brasiliensis é um Sciaenidae comum no bycatch da pesca de arrasto do camarão sete-barbas (X. kroyeri) no sul do Brasil. A despeito de sua importância ecológica, estudos sobre os hábitos alimentares dessa espécie são ainda incipientes (COSTA et al., 2012). Assim, esse trabalho tem como objetivo analisar os hábitos alimentares de P. brasiliensis, a fim de se avaliar o impacto da pesca de arrasto sobre as cadeias alimentares marinhas costeiras do sul do Brasil.
