Our findings reveal that the acquisition of an exclusive mechanism controlling the sperm plasma membrane Na+ gradient, critical for glucose uptake, emerged in the ancestor of mammals through gene duplication, which originated the Na+/K+ ATPase transporting subunit alpha 4 transporter (Atp1a4). Furthermore, we demonstrate that testis-specific expression of Atp1a4 was acquired after the divergence from monotremes.

The recurrent loss of function in Atp1a4 coincides with the erosion of the testis-specific glycolytic pathway in these lineages. Furthermore, enrichment analysis of striped dolphin (Stenella coeruleoalba) and naked mole-rat testis transcriptomes also suggests significant alterations in sperm capacitation processes. Overall, we show that the elaboration of a sodium-dependent glucose uptake wiring was a key innovation in the energetic landscape governing mammalian spermatozoa, with secondary gene loss in three separate lineages pointing to drastic alterations in motility and capacitation processes.

Application of the validated method to zooplankton collected around Madeira Island (Portugal) revealed the presence of six oUVFs. Homosalate was the most frequently detected compound (53 % of samples), while octocrylene exhibited the highest concentrations, ranging from 24.01 to 1029 ng g−1 d.w. These findings demonstrate the relevance of zooplankton as bioindicators of oUVF contamination and support the need for regulatory monitoring and ecological risk assessments in coastal ecosystems.

In southern Scandinavia, a lack of spatially-resolved data on harbour seal populations poses a major challenge for developing ecologically informed management frameworks, particularly in Norway, where populations are regulated using county-level administrative boundaries. In this study, we use haul-out data from 26 harbour seals tagged with GPS phone tags during the post-moult period to provide the first assessment of connectivity and movement across management boundaries in the Skagerrak–Kattegat region of southern Scandinavia. Specifically, we examined the frequency and timing of haul-out events relative to management units and quantified spatial networks of connectivity across national and sub-national jurisdictions. We reveal a high degree of spatial connectivity in the region, with haul-outs occurring over a broad, integrated network along the Skagerrak–Kattegat coastline. Generally, harbour seals in the region had a high probability of performing cross-boundary haul-out events, with individuals repeatedly transitioning across distinct Norwegian management units, as well as transnationally between Norway, Sweden and Denmark. This study offers critical insights into harbour seal movement ecology in this data-limited region, whilst also addressing an important topic of applied management. We demonstrate that the current management units in the Norwegian Skagerrak may not adequately reflect the spatiotemporal scales of harbour seal movement. Importantly, these findings can complement forthcoming genetic data and support efforts to redefine management units in the area. More broadly, our study illustrates how telemetry-based assessments of spatial connectivity can provide a powerful tool to inform management frameworks for other wide-ranging marine species facing similar conservation challenges.},

To address this issue, retailers require innovative technologies that enhance stock estimation and influence customer behavior. Monitoring systems that track expiration dates and assess the quality of organic products show promise, but they must be easy to deploy, maintain, and scale for widespread adoption. We introduce BEE, an innovative solution for produce quality estimation that leverages collaborative heat-based bio-sensing from customer interactions. BEE addresses a critical gap in current solutions: lack of user-friendly approaches that are easy to deploy and manage. BEE operates by capturing superficial heat residuals left by customers interacting with fresh produce using a thermal camera, which are then used to construct thermal dissipation profiles that enable accurate quality estimation. Constructing these profiles from sparse and variable thermal residuals in different environments, however, is highly challenging. To overcome this challenge, the key innovations in BEE are the use of opportunistically collected thermal residuals for profiling produce, integration of novel AI image enhancement techniques for improving the quality of thermal residual, AI-based calibration to overcome variations in interactions and consumer characteristics, and a novel computer vision pipeline to facilitate effective estimation. We validate the practicality of BEE through rigorous experiments, demonstrating its ability to capture decay patterns from human heat residuals. Our results indicate that BEE can achieve over 95% accuracy in estimating produce quality while operating robustly across varying environmental conditions and outperforming existing state-of-the-art solutions.

Here, we present daily estimates of nutrient input by baleen whales in high-latitude feeding grounds (Nordic and Barents Seas), based on multielement analyses of feces and urine. We then used end-to-end ecosystem models to assess the impact of these nutrients on primary production. We found that nitrogen is primarily excreted via urine, whereas phosphorus and trace elements are mainly released through feces.

While the annual effects are modest (<2%) in most areas, the greatest impacts (up to 10%) occur during summer stratification and in offshore areas far from other nutrient sources. These increases in primary production have cascading effects on the food web, driving rises in mesozooplankton biomass.

This study assessed oUVFs contamination in the blubber of two deep-diving cetacean species —the short-finned pilot whale (Globicephala macrorhynchus) and the sperm whale (Physeter macrocephalus)—off Madeira Island, Eastern North Atlantic. Using microwave-assisted extraction and UHPLC-MS/MS, four of eleven targeted oUVFs were detected in blubber: homosalate, 2-ethylhexyl salicylate, octocrylene, and methylene bis-benzotriazole (UV-360). Concentrations reached up to 352.3 ng/g wet weight (w.w.) in pilot whales and 1505 ng/g w.w. in sperm whales. Detection frequencies were higher in pilot whales (60–100 %) than in sperm whales (30–50 %). This study provides the first evidence of UV-360 concentration in cetaceans. These findings suggest that pilot whales’ higher site fidelity in Madeiran waters may increase exposure to oUVF, while sperm whales may accumulate oUVFs through benthopelagic feeding at higher trophic levels. These results highlight the potential for oUVF to disperse into deep marine ecosystems and underscore the importance of monitoring emerging contaminants in oceanic apex predators.},

The increasing use of personal care products has led to the widespread of organic UV filters (oUVFs) in marine ecosystems, yet their occurrence and potential impacts on pelagic and deep-sea environments remain unclear. This study assessed oUVFs contamination in the blubber of two deep-diving cetacean species —the short-finned pilot whale (Globicephala macrorhynchus) and the sperm whale (Physeter macrocephalus)—off Madeira Island, Eastern North Atlantic. Using microwave-assisted extraction and UHPLC-MS/MS, four of eleven targeted oUVFs were detected in blubber: homosalate, 2-ethylhexyl salicylate, octocrylene, and methylene bis-benzotriazole (UV-360). Concentrations reached up to 352.3 ng/g wet weight (w.w.) in pilot whales and 1505 ng/g w.w. in sperm whales. Detection frequencies were higher in pilot whales (60–100 %) than in sperm whales (30–50 %). This study provides the first evidence of UV-360 concentration in cetaceans. These findings suggest that pilot whales’ higher site fidelity in Madeiran waters may increase exposure to oUVF, while sperm whales may accumulate oUVFs through benthopelagic feeding at higher trophic levels. These results highlight the potential for oUVF to disperse into deep marine ecosystems and underscore the importance of monitoring emerging contaminants in oceanic apex predators.
