- Conceptualization of sustainable higher education institutions, roles, barriers, and challenges for sustainability: an exploratory study in PortugalPublication . Aleixo, Ana Marta; Leal, Susana; Azeiteiro, UlissesHigher Education Institutions play an important role in the promotion of sustainability and an increasing number of stakeholders expect them to be sustainable organizations. However, this can only be achieved when barriers are faced and challenges overcome. This exploratory study aims to investigate how the main stakeholders (leaders, faculty, staff, students, and external stakeholders) of Portuguese Public Higher Education Institutions perceive: the concepts of sustainability and sustainable higher education institutions, the role of higher education for sustainable development, and the barriers, challenges and obstacles to implementing sustainable initiatives in Portuguese Public Higher Education Institutions. Through a qualitative approach, using semi-structured interviews and content analysis procedures, this article explore the perspectives of twenty stakeholders from four Portuguese Public Higher Education Institutions. The results suggest that, although aware of the concept of sustainability, the different stakeholders are not familiar with the concept of sustainable higher education institutions. The lack of financial resources due to the decline in funding for higher education and falling numbers of Portuguese university students is perceived as the main barrier to sustainable development in higher education (i.e. practices are still associated with spending financial resources). This research highlights the importance of a conceptual and organizational change in higher education institutions, notably through identifying new sources of financing, more flexible organizational forms, more comprehensive mission statements, more tailored educational offers, life-long learning and commitment to internationalization, and more strategic human resource management. The paper contributes to the literature by reflecting on how higher education institutions can promote sustainability, how higher education for sustainable development is understood and can be improved in Portuguese Higher Education Institutions.
- Dynamics of Decapoda larvae communities in a southwest Iberian estuary: Understanding the impact of different thermal regimesPublication . Monteiro, Marta; Cruz, Joana; Azeiteiro, Ulisses; Marques, Sónia Cotrim; Baptista, Vânia; Teodosio, Maria AlexandraEnvironmental conditions play a pivotal role in shaping the dynamics of meroplanktonic communities, which represent a vital life stage, crucial for successful recruitment. Specifically, temperature can impact the survival and duration of larval development in decapod crustacean species. The objective of this study is to analyze the community of decapod larvae in the Guadiana estuary, located in southwest Iberia. The analysis focuses on the community's taxonomic composition, temporal variability, and the influence of environmental factors. Particularly, the study emphasizes investigating the impacts of different thermal regimes on the abundance of these assemblages. A comprehensive zooplankton sampling program was conducted at a single station in the lower estuary, from 2014 to 2022. The decapod larvae assemblages are dominated by Upogebia spp., followed by Diogenes pugilator, Panopeus africanus, Afropinnotheres monodi, and Polybius henslowii species. The results of structural equation modeling unveiled a strong influence of water temperature and salinity on the community, while chlorophyll-a concentration, river runoff, and the large-scale climatic mode North Atlantic Oscillation (NAO) revealed no impact on the abundance of these assemblages. Overall, the community and the main taxa displayed a positive linear trend in response to increased salinity. However, the effect of increasing temperature varied among species. In the current climatic scenario, water temperature emerges as a critical factor in predicting seasonal variation of the assemblages' abundances, exhibiting a marked seasonality during spring and summer. Predictive models used to investigate future scenarios, Representative Concentration Pathway (RCP) 2.6 and RCP 8.5, defined by the International Panel on Climate Change (IPCC), where the temperature is expected to rise 2 °C and 4.3 °C by 2100, suggest the possibility for an alteration in assemblages' composition, where the abundances of D. pugilator, the second most abundant species, tend to decrease abruptly. Reported evidence, coupled with the typical Mediterranean climate of the region, where extreme climatic events, like marine heatwaves, are becoming more frequent, the high connectivity with the Mediterranean Sea, where invasion by non-indigenous species is increasing, also connected with changes in freshwater discharges, may trigger significant alterations in species dominance and abundance, with ecological and socio-economic implications.
- Evidence for changes in estuarine zooplankton fostered by increased climate variancePublication . Marques, Sónia Cotrim; Pardal, Miguel Ângelo; Primo, Ana Lígia; Martinho, Filipe; Falcão, Joana; Azeiteiro, Ulisses; Molinero, Juan CarlosEstuaries are among the most valuable aquatic systems in terms of their services to human welfare. They offer an ideal framework to assess multiscale processes linking climate and food web dynamics through the hydrological cycle. Resolving food web responses to climate change is fundamental to resilience management of these threatened ecosystems under global change scenarios. Here, we examined the temporal variability of the plankton food web in the Mondego Estuary, central Iberian Peninsula, over the period 2003 to 2012. The results pointed out a cascading effect from climate to plankton communities that follow a non-stationary behavior shaped by the climate variance envelope. Concurrent changes in hydrographic processes at the regional, that is, upwelling intensity, and local, that is, estuarine hydrology, scales were driven by climatic forcing promoted by the North Atlantic Oscillation; the influence of which permeated the physical environment in the estuary affecting both autotrophic and heterotrophic communities. The most conspicuous change arose around 2008 and consisted of an obvious decrease in freshwater taxa along with a noticeable increase in marine organisms, mainly driven by gelatinous zooplankton. The observed increase in small-sized cosmopolitan copepods, that is, Clausocalanus arcuicornis, Oithona plumifera, thermophilic species, that is, Penilia avirostris, and gelatinous zooplankton suggests a structural change in the Mondego plankton community. These results provide empirical support to the expectation that expanding climate variance changes plankton structure and functioning, likely fostering trophic interactions in pelagic food webs.
- Higher education students’ perceptions of sustainable development in PortugalPublication . Aleixo, Ana Marta; Leal, Susana; Azeiteiro, UlissesHigher education institutions play an increasingly important role in advancing sustainable development. Various studies have demonstrated the key contribution made by teachers to achieving sustainable development. However, few works have addressed students’ perceptions in this regard and given that the students of today will be the main influencers and decision-makers of the future, a greater understanding of their beliefs and attitudes towards sustainable development should be gleaned. The aim of this research is to analyse the perceptions of sustainable development held by students at Portuguese public higher education institutions. To this end, a descriptive and exploratory study was conducted by administering an online questionnaire. The sample is made up of 1257 students from different Portuguese public higher education institutions (68.6% women; average age 24.96 years). The results show that although the students recognise the importance of sustainable development and most of them have already heard about the sustainable development goals (16% never heard about them), they believe that the higher education institutions could and should give more training on this matter. Most students state that they would accept a lower salary from a company with a good social and environmental performance in some circumstances. The majority also have pro-sustainability habits and behaviours. Most of the students are concerned about climate change, most speak of some reusing, reducing and recycling practices, but fewer students contribute to sustainable development by participating in activities (e.g., environmental or community volunteering) organised by environmental organisations or the higher education institution. Differences in the behaviours and habits related to sustainability were observed between the students of different genders, ages and scientific areas. The results further present four clusters of students regarding their perception of sustainable development and related practices. The largest cluster (about 45%) includes students who are more concerned about climate change, actively contribute to sustainable development with reuse, reduction and recycling practices, and participate in organised activities to promote the protection of the environment or society. The smallest cluster (about 8%) includes students who are still sceptical about climate change and therefore adopt less environmentally friendly practices. Five years after the publication of the sustainable development goals, students feel that sustainability is starting to be integrated in education. However, the impact on their behaviours and attitudes remains moderate.

- Rankings and sustainability in Portuguese higher education institutions: a descriptive analysisPublication . Aleixo, Ana Marta; Leal, Susana; Leal Filho, Walter; Mendes, Susana; Azeiteiro, UlissesThe issue of ranking in Higher Education Institutions (HEIs) has produced a growing body of literature at an international level that is focused on metaanalysis. However, there is still comparably little discussion on the subject of Higher Education (HE) in Portugal. This paper strives to fill this gap. This research was conducted using the Portuguese public HEIs websites and presents a critical review of HEIs rankings in Portugal. These are the types of Higher Education Institution (HEI) rankings that are concerned with the promotion of sustainable development rankings. The links between rankings and institutional commitment, advanced sustainability or the promotion of a positive image are discussed. This work results in the preliminary discussion of a proposal for an alternative ranking for Sustainable Development (SD) in HEIs. An alternative ranking would take the system and subsystem activities of HEIs into consideration, and would constitute a starting point for further discussion when it comes to the development of the ranking for sustainability in HEIs in responding to the issue of holistic and integrated sustainability in Portuguese public HEIs.
- Students’ perspectives on sustainable development goals in Portuguese higher education institutionsPublication . Aleixo, Ana Marta; Leal, Susana; Azeiteiro, UlissesIn this paper, we present a research about the understanding of sustainable development (SD) among students of public higher education institutions, in Portugal. It explores the students’ perspectives about SD through the analysis of their attitudes, skills and experiences on the theme. Their knowledge about sustainable development goals (SDGs) and their opinion about the importance of SD as future professionals were also under consideration. The research design of the study follows a descriptive and exploratory approach with a quantitative reporting of results. It was used an on-line questionnaire, adapted from the National Union Students (2018), Chuvieco et al. (2018) and Dagiliūtė et al. (2018). A sample of 1257 students from the Portuguese public higher education institutions (HEIs) was obtained. In general, the results show that students have knowledge about environmental issues. Students study, at different degrees, subjects related to SD and SDGs, however participation and involvement is lacking. It is urgent to introduce SD education in all curricula. In addition, most students already have heard about SDGs and know what they are, however, only a small number of students are actively involved in activities organized by their HEIs. Students also consider that secondary education was the educational path that most encouraged to think and act in ways that help the environment and people. Students consider that HEIs can do more in terms of education for SD. From a global perspective, this study corroborate the three previous studies, namely the factors associated to more pro-environmental attitudes and behaviours are still poorly understood. This research has a national scope and the results should be interpreted only in the Portuguese context. Future studies should include a larger range of institutional actors within the faculty. The study helps to better understand the students’ perceptions about SD and the role of HEIs to improve it, namely in Portugal where the studies about the theme are scarce. The results could be used by HEIs to introduce the SD topics in formal and informal education, as well as to improve it integration on campus activities.
