Summary: Estimating seabird and pinniped abundance is crucial in Antarctica's wildlife management and ecosystem monitoring. Unoccupied aerial systems (UAS) can collect images to support monitoring, and automating target detection using deep learning techniques may improve data acquisition. However, the choice of image sensors and training data can affect model performance.

Summary: The aim of this study was to assess the safety of bee drone brood in terms of contamination risk and sensory acceptability. The analysis found that drone brood has a good mineral content and low microbial levels, making it a potentially safe food source. However, there were differences in taste between the oatmeal ball and drone brood ball.

Summary: The researchers aimed to design an innovative dietary supplement containing freeze-dried drone brood enriched with calcium ions. They found that the components of drone brood were more bioaccessible from the supplements enriched with ground chicken eggshell compared to those enriched with calcium carbonate. This newly proposed two-ingredient supplement shows potential for treating osteoporosis but further studies are needed.

Summary: The study aimed to evaluate the use of high-resolution UAV images for identifying forest species in areas of forest regeneration in the Amazon. By training convolutional neural networks with different thresholds, the results showed that CNN can accurately identify species with over 90% accuracy. The study concluded that CNN is an effective tool for classifying species in UAV images.

Summary: This article introduces the development of a multicopter system to study the vertical distribution of pollutants, various user requirements, system setup, instrumentation, and initial application results. Research found that the vertical distribution of particulate matter next to highways is closely related to atmospheric stratification, with different concentrations changing with temperature inversions.

Summary: Effective methods for tree delineation and species classification in an Australian native forest were identified in this study. The study found that the highest classification accuracies were achieved at the superpixel scale, and the DeepForest method showed potential for tree detection compared to conventional methods.

Summary: The study found that drone brood has higher antioxidant activity in the early stages of larval development and is mainly composed of hydrophilic antioxidants. Freeze-drying did not significantly affect the antioxidant activity of brood preparations. HPTLC analysis indicated that the polyphenolic fraction of drone brood homogenate consists mainly of phenolic acids and flavonoids.

Summary: Understanding population trends of hippos in Ndumo Game Reserve is crucial, with data showing a decline in numbers over the past 40 years. Collaboration between conservation authorities, South African government departments, and local communities is recommended to protect hippos and other wildlife by reestablishing reserve boundaries.

Summary: The thermal adjustment of non-breeding waterbird communities to climate warming in the Mediterranean region was assessed to identify priority sites for wetland protection. The study found that strictly protected areas could support the thermal adjustment of waterbird communities, but there is a need to strengthen the protected areas network in at-risk sites. This study provides important guidance for conservation planning in the Mediterranean region to support waterbird responses to climate change.

Summary: The flow field induced by multirotor drones is of great importance for atmospheric research as it affects atmospheric sensors and can cause interference with measurement equipment. A study combining pressure and temperature measurements, numerical simulations, and laboratory tests was conducted to investigate the near flow field of a quadcopter system.

Summary: Despite a lack of understanding in the behavioral development of young songbirds, technological advances have allowed for more robust examinations. This study used automated radio-telemetry systems to document post-fledging activity rates of juveniles across different species in Illinois. Findings showed similarities in fledgling activity rates, with a steady increase before leveling off around 3 to 4 weeks post-fledging. The study also highlighted the influence of wing development and brood size on fledgling activity rates.

Summary: This study investigated how the distribution of breeding individuals and breeding success of waterbirds in Southeastern Finland changed along gradients in ice-out date and habitat structure. The research found significant differences in distribution and breeding success of different species along environmental gradients. The potentially positive impact of climate change on breeding phenology was outweighed by negative changes in habitat quality.

Summary: Goose and swan populations have increased alongside the degradation of wetlands, but they do not negatively affect other trophic levels. The abundance of geese and swans is positively related to other waterbird guilds, specific macrophytes, and invertebrate richness and abundance. Productive wetlands support higher abundance of waterbirds, indicating that geese and swans benefit from the environmental changes.

Summary: This study investigated the dynamics of biodiversity change in local waterbird communities and the relative role of eutrophication and alien predators. The results showed contrasting trends in species richness and total abundance between historical and current time series, as well as differences in habitat specialists and generalists. The study also found that increased predation has been an important driver of population and biodiversity declines in waterbird communities.
