Introduction Citizen science is increasingly recognised as a valuable approach for monitoring marine non-indigenous species (NIS), range-expanding species (RES), and cryptogenic taxa. This study evaluates the outcomes of the Spot the Alien campaign in Maltese waters between 2022 and 2025. Methods A total of 441 expert-validated records of 30 NIS, RES and cryptogenic species were analysed to assess temporal and spatial reportin...
Marine megafauna species are affected by a wide range of anthropogenic threats. To evaluate the risk of such threats, species’ vulnerability to each threat must first be determined. We build on the existing threats classification scheme and ranking system of the International Union for Conservation of Nature (IUCN) Red List of Threatened Species by assessing the vulnerability of 256 marine megafauna species to 23 at‐sea threat...
Influence of food processing conditions on the technofunctional properties of the red seaweed Pyropia columbinaNARA Subscribed
The edible seaweed Pyropia columbina thrives along coastlines worldwide and is rich in water-soluble sulfated galactans with valuable technofunctional properties for innovative applications. However, the impact of processing on P. columbina remains largely unexplored, limiting its application as an ingredient in food products. The objective of this study was to investigate P. columbina dispersions obtained by food processing i...
Cortical volumetry and longitudinal cognitive changes in Parkinson’s disease: insights from the COPPADIS cohortNARA Subscribed
Cognitive decline is a major non-motor symptom in Parkinson’s disease (PD), often linked to brain atrophy. This study examines the relationship between cortical atrophy and age groups in predicting cognitive decline in PD over five years. 188 PD patients from the COPPADIS cohort were stratified by age: young (30–55 years, N = 47), middle-aged (56–65 years, N = 59), and older adults (66–75 years, N = 82). Baseline cortical volu...
The pleustonic, open-ocean dweller Physalia physalis can reach European Atlantic coasts when the combination of wind and currents drags the colonies from their typical habitats in the open ocean towards these shores. Usually, this passive advection happens during the winter months, when low-pressure atmospheric systems typically move from west to east accompanied by strong westerly winds. This is particularly fortunate for hum...
Nine decades of data on environmental chemical pollutant exposure in dogs: a bibliometric analysisNARA Subscribed
In recent decades, a global concern associated with environmental chemical contamination has emerged as an important risk factor for the development of human diseases. Risk assessment methods based on animal approaches have shown to be very useful as early warning systems. However, questions, knowledge gaps, and limitations still need to be addressed in animals close to humans, such as dogs. The objective of this study was to...
A search of records from different kinds of sources namely, scientific and grey literature, social media, and zoological museum collections, has been carried out to review the incidence of Physalia physalis (Linnaeus, 1758), the Portuguese man-of-war, in the Mediterranean Sea. The temporal frame of the records, considered valid if documented with images or collected specimens, ranged from the second half of the eighteenth cent...
The photosymbiosis with host-specific dinoflagellates is a widespread relationship in marine organisms. Despite the evidenced biodiversity of this kind of mutualism, most research focuses on the study of scleractinian corals, and there is a lack of knowledge about other symbiotic cnidarians such as jellyfishes. The Mediterranean jellyfish Cotylorhiza tuberculata (Rhizostomae, Scyphozoa) harbors an endosymbiotic dinoflagellate...
Spawning site distribution of a bluefin tuna reduces jellyfish predation on early life stagesNARA Subscribed
Bluefin tunas across the world migrate long distances to spawn in particularly warm and oligotrophic areas constrained by oceanographic fronts. The low abundance of predators in these areas increases survival chances of their early life stages, but its importance for choice of spawning habitat is unknown. Here, we use estimated clearance rates and data on spatial distributions of Atlantic bluefin tuna larvae Thunnus thynnus an...
NEOTROPICAL ALIEN MAMMALS: a data set of occurrence and abundance of alien mammals in the NeotropicsNARA Subscribed
Biological invasion is one of the main threats to native biodiversity. For a species to become invasive, it must be voluntarily or involuntarily introduced by humans into a nonnative habitat. Mammals were among first taxa to be introduced worldwide for game, meat, and labor, yet the number of species introduced in the Neotropics remains unknown. In this data set, we make available occurrence and abundance data on mammal specie...
