Coastal lagoons in the United Arab Emirates serve as critical habitats for globally threatened marine megafauna.

Shallow coastal lagoons are vital ecosystems for many aquatic species and understanding their biodiversity is essential. Very little is known about the distribution and abundance of globally threatened marine megafauna in coastal lagoons of the Arabian Gulf. This study combined underwater and aerial surveys to investigate the distributions and relative abundance of marine megafauna in a large lagoon. We identified 13 species of megafauna including sea turtles, sharks, and rays. Eleven of these are globally threatened according to the IUCN Red List of Threatened Species. The Critically Endangered Halavi guitarfish (Glaucostegus halavi), and the Endangered green turtle (Chelonia mydas) were the most frequently occurring species. Results demonstrate the value of combining aerial and underwater video surveys to obtain spatially comprehensive data on marine megafauna in shallow coastal lagoons. This new information emphasises the importance of Umm Al Quwain lagoon for biodiversity conservation to protect threatened marine species and their habitats.

Applying an integrated approach to coastal marine habitat mapping in the north-western United Arab Emirates.

Habitat mapping is essential for the management and conservation of coastal marine habitats. However, accurate and up-to-date habitat maps are rarely available for the marine realm. In this study, we mapped the coastal marine habitats of >400 km of coastline in the north-western United Arab Emirates (UAE) using a combination of data sources including remote sensing, extensive ground-truthing points, local expert knowledge and existing information. We delineated 17 habitats, including critical habitats for marine biodiversity such as coral reefs and mangroves, and previously unreported oyster beds and deep seagrasses. This innovative approach was able to produce a coastal marine habitat map with an overall accuracy of 77%. The approach allowed for the production of a spatial tool well-suited for the needs of environmental management and conservation in a previously data-deficient area of the United Arab Emirates.

Evaluating Mediterranean diet adherence in university student populations: Does this dietary pattern affect students' academic performance and mental health?

Adherence to a healthy diet such as Mediterranean Diet (MD) may exert beneficial effects in university students, promoting their academic performance and quality of life, as well as their mental and physical health status. In this aspect, the present study aimed to critically analyze the current epidemiological evidence concerning MD adherence of university students' populations. PubMed database was comprehensively searched, using relative keywords. Students' dietary habits are moving away from MD guidelines towards unhealthy eating patterns, especially for those living away from home and even for students with a Mediterranean country origin. Most of the available studies have documented that poorer students' health status was associated with lower MD adherence. Higher MD adherence was correlated with lower depression risk, while higher perceived stress score with lower fruit and vegetables intake. The access of students to information and knowledge provided by courses and lectures did not effectively enhance their compliance to MD. Alarmingly enough, the majority of students, even from medical and nutritional university departments, showed inadequate knowledge on healthy eating habits. Due to the influence of diet on the quality of life and the mental and physical health of students, it is crucial to redirect research focus on this important aspect.
