This study provides novel knowledge on the natural markings and population parameters of Blainville’s beaked whales (Mesoplodon densirostris). Using photographic-identification data from adults and subadults of both sexes in Madeira Island (Eastern North Atlantic, 2015–2020), we estimated abundance and survival using capture-recapture models, the Robust Design (RD) and the POPAN. We calculated the proportion of marked individuals (i.e., at least slightly distinctive) as 0.88, with new marks appearing every 0.4 years (range = 0.1–0.7). Annual abundance estimates from both models were similar and showed no trend. The corrected annual abundance estimates from the POPAN best-fitting model ranged from 42 whales (95% CI = 39–46 in 2016, and 95% CI = 39–48 in 2019) to 61 (95% CI = 51–72 in 2015). The POPAN model estimated a corrected super-population of 112 individuals (95% CI = 99–134) between 2015 and 2020. Survival rates of 0.98 (95% CI = 0.83–1.0) and 0.99 (95% CI = 0.97–1.00) were estimated (excluding transients) from the RD and POPAN models, respectively, which are similar to other regions. Despite potential caveats discussed in our analysis, these plausible estimates for a relatively small population should be considered in conservation and management strategies, highlighting the need to monitor the potential impact of local human activities.},

Population parameters have been studied for only five out of 24 beaked whale species in limited locations. This study provides novel knowledge on the natural markings and population parameters of Blainville’s beaked whales (Mesoplodon densirostris). Using photographic-identification data from adults and subadults of both sexes in Madeira Island (Eastern North Atlantic, 2015–2020), we estimated abundance and survival using capture-recapture models, the Robust Design (RD) and the POPAN. We calculated the proportion of marked individuals (i.e., at least slightly distinctive) as 0.88, with new marks appearing every 0.4 years (range = 0.1–0.7). Annual abundance estimates from both models were similar and showed no trend. The corrected annual abundance estimates from the POPAN best-fitting model ranged from 42 whales (95% CI = 39–46 in 2016, and 95% CI = 39–48 in 2019) to 61 (95% CI = 51–72 in 2015). The POPAN model estimated a corrected super-population of 112 individuals (95% CI = 99–134) between 2015 and 2020. Survival rates of 0.98 (95% CI = 0.83–1.0) and 0.99 (95% CI = 0.97–1.00) were estimated (excluding transients) from the RD and POPAN models, respectively, which are similar to other regions. Despite potential caveats discussed in our analysis, these plausible estimates for a relatively small population should be considered in conservation and management strategies, highlighting the need to monitor the potential impact of local human activities.

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.

abstract = {Seagrasses are highly sensitive to human-induced disturbances and global environmental changes. Since the 1980s, Zostera marina meadows along the West Swedish coast (Skagerrak) have declined significantly, as evidenced by changes in morpho-anatomical traits, reductions in area coverage, and shifts in associated communities. However, infaunal assemblages within Z. marina meadows remain understudied compared to epifaunal communities and have not been previously used as indicators of seagrass regression. To investigate spatial variability in infaunal composition, we analysed samples from 15 coastal stations at depths of 1.5–3 m depth. Using an n-dimensional hypervolume framework, we assessed functional differences between infaunal and epifaunal communities. We examined infaunal community descriptors—such as species richness and individual abundance—biotic indices, environmental drivers (including wave exposure and Z. marina biomass), and correlations with epifauna. Variability in infaunal composition across sampling stations was primarily driven by differences in the abundance of dominant taxa, including the polychaete Capitella capitata, oligochaetes, nematodes, and chironomids. Several coastal stations, such as Marstrand and Finsbo, were classified as moderately polluted, though biotic indices, i.e., AMBI, M-AMBI and ISI, showed discrepancies. Spatial patterns in infaunal assemblages were mainly influenced by Z. marina biomass and maximum fetch, with a good representation of oligochaetes and chironomids in exposed stations. These findings suggest that infauna respond differently from epifauna but provide valuable additional insights into the ecological status, functional traits, and trophic diversity of Z. marina meadows. Integrating multiple community components is essential for a more comprehensive understanding of the processes and patterns driving seagrass ecosystem regression.},

abstract = {Whales have long been suggested to enhance ocean productivity by recycling essential nutrients, yet their quantitative impact on primary production has remained uncertain. Our study quantifies nutrient release via feces and urine by baleen whales in high-latitude feeding grounds and evaluates its impact on primary production using ecosystem models. Results indicate that whales enhance ocean productivity, particularly in offshore regions where nutrients are scarce, leading to cascading effects on the food web. These findings highlight the ecological importance of whale-mediated nutrient cycling and emphasize the role of whale populations in sustaining productive and resilient marine ecosystems. Primary production in the ocean is a fundamental process that supports marine food webs and global carbon sequestration. This process depends on nutrients that are often limited in surface waters. Whales are known to release essential elements such as nitrogen, phosphorus, and iron, yet the extent of their contribution to ocean primary production remains unclear. 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. Ecosystem models indicate that baleen whales, including minke, fin, sei, humpback, blue, and bowhead whales, support annual and seasonal net primary production, with varying impacts across space and time. 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 highlights the ecological significance of nutrient cycling by whales and underscores the value of integrating whale nutrient data into ecosystem modeling to assess the broader impacts of whales on marine productivity.},
