The Lepidopteran Hitchhiker's Guide to the Globe: The Spread and Dispersal of Non‐Native Moths and ButterfliesNARA Subscribed
Aim To assess the diversity, temporal dynamics, and global distribution of non‐native Lepidoptera. Location Global, encompassing 258 non‐overlapping geopolitical regions comprising countries and distinct insular territories. Time Period ~1500 ce to the present. Major Taxa Studied Lepidoptera species, with distinctions between moths and butterflies. Methods We developed a global dataset of the distribution and timing of first r...
Marine fossil records hold outstanding importance for ecological, evolutionary and biogeographical studies. Santa Maria Island in the Azores Archipelago (central Atlantic) features a remarkable marine fossil record spanning from the Pliocene to recent times. This record includes late Pleistocene outcrops with fossiliferous deposits dated from the last interglacial period (MIS 5e). In this study, we describe a newly discovered...
Status and biology of hawksbill turtles at Poilão Island, Guinea-Bissau: a key stronghold for the species in West AfricaNARA Subscribed
This study provides the first detailed assessment of the hawksbill turtle ( Eretmochelys imbricata ) nesting population from Poilão island, in the Bijagós archipelago of Guinea-Bissau, the only documented regular nesting site for this species in West Africa. Over 17 years, from 2007 to 2024, 29 females were tagged, with one to six individuals nesting annually, some for more than 10 years. Nesting occurs from July to November,...
Nutrient Input from Green Turtle Eggs and Hatchlings in a West Africa Island and Its Nearshore EnvironmentNARA Subscribed
Sea turtle nesting brings marine-derived nutrients into sandy beach ecosystems, potentially influencing their dynamics. We investigated nutrient input from green turtle Chelonia mydas eggs and hatchlings into coastal habitats in Guinea-Bissau, West Africa. We assessed two islands within the João Vieira-Poilão Marine National Park (‘JVPMNP’), with contrasting sea turtle nesting density: very low (João Vieira) and very high (Poi...
Understanding spatial heterogeneity in reproductive success among at-risk populations facing localised threats is key for conservation. Sea turtle populations often concentrate at one nesting site, diverting conservation efforts from adjacent smaller rookeries. Poilão Island, Bijagós Archipelago, Guinea-Bissau, is a notable rookery for green turtles Chelonia mydas within the João Vieira-Poilão Marine National Park, surrounded...
Rhodolith beds and their onshore transport in Fuerteventura Island (Canary Archipelago, Spain)OA Marine
Rhodoliths occur extensively around the shores of Fuerteventura Island in the Canary Archipelago, with Lithothamnion cf. corallioides being the most prominent species. A large number of rhodoliths end up washed onshore, the debris from which contributes to the formation of sediments constituting modern beaches. In a previous study by one of the co-authors (MEJ), the northern coast of Fuerteventura was shown to comprise various...
Green turtles ( Chelonia mydas ) are highly dependent on neritic foraging areas throughout much of their life. Still, knowledge of recruitment dynamics, foraging habits, and habitat use in these areas is limited. Here, we evaluated how the distribution and food preferences of green sea turtles from different life stages varied within a foraging aggregation. We focused on two islands in Guinea-Bissau, Unhocomo and Unhocomozinho...
MAMMALS IN PORTUGAL : A data set of terrestrial, volant, and marine mammal occurrences in P ortugalNARA Subscribed
Mammals are threatened worldwide, with ~26% of all species being included in the IUCN threatened categories. This overall pattern is primarily associated with habitat loss or degradation, and human persecution for terrestrial mammals, and pollution, open net fishing, climate change, and prey depletion for marine mammals. Mammals play a key role in maintaining ecosystems functionality and resilience, and therefore information o...
Growth modelling is essential to inform fisheries management but is often hampered by sampling biases and imperfect data. Additional methods such as interpolating data through back-calculation may be used to account for sampling bias but are often complex and time-consuming. Here, we present an approach to improve plausibility in growth estimates when small individuals are under-sampled, based on Bayesian fitting growth models...
Enhancing knowledge on low‐value fishing species: the distinct reproductive strategy of two gurnard speciesNARA Subscribed
The depletion and overexploitation of several fish stock demands for a valorisation of non‐target and discarded species. Nonetheless, such species are often poorly studied, and information on their biological parameters must be gathered for effective population management. For 1 year, the reproductive strategy of the piper gurnard Trigla lyra and the red gurnard Chelidonichthys cuculus was studied by monthly samples obtained f...
Motivation The BioTIME database contains raw data on species identities and abundances in ecological assemblages through time. These data enable users to calculate temporal trends in biodiversity within and amongst assemblages using a broad range of metrics. BioTIME is being developed as a community‐led open‐source database of biodiversity time series. Our goal is to accelerate and facilitate quantitative analysis of temporal...
Invasive alien predators can impose strong selection on native prey populations and induce rapid evolutionary change in the invaded communities. However, studies on evolutionary responses to invasive predators are often complicated by the lack of replicate populations differing in coexistence time with the predator, which would allow the determination of how prey traits change during the invasion. The red swamp crayfish Procam...
