UAV Data Collection Co-Registration: LiDAR and Photogrammetric Surveys for Coastal Monitoring
DronesWhen georeferencing is a key point of coastal monitoring, it is crucial to understand how the type of data and object characteristics can affect the result of the registration procedure, and, above all, how to assess the reconstruction accuracy. For this

Boreas, Volume 55, Issue 3, Page 612-669, July 2026.We present a 25‐stage reconstruction of the ice‐flow pattern evolution of the Scandinavian Ice Sheet based on mapping and analysis of ~240 000 subglacial lineations and lineation fields across Norway, Sweden, Finland, and parts of NW Russia. Our reconstruction uses a glacial geomorphological inversion approach, in which we generated 611 individual ...

European Journal of Soil Science, Volume 77, Issue 4, July/August 2026.ABSTRACT Soil profiles are the primary field evidence from which pedogenesis, soil classification and land‐use effects are interpreted, yet their availability remains uneven across climates and land‐cover contexts. Here, we analyse the World Soil Information Service (WoSIS) 2023 snapshot together with Copernicus Global Land Cover 2015 and the global ...

Surface grain-size mapping of braided channels from SfM photogrammetry [PDF]
Earth Surface DynamicsBraided channels are known as fluvial systems with a high heterogeneity of physical conditions, resulting from particularly active interacting processes of coarse sediment sorting and transport.

Aquaculture, Fish and Fisheries, Volume 6, Issue 3, June 2026.ABSTRACT The ‘Ten‐Year Fishing Ban’ policy in the Yangtze River Basin has compelled over 230,000 fishermen to cease fishing and transition to alternative livelihoods, making their post‐ban livelihood development critical to the policy's long‐term effectiveness. Drawing on household survey data from Hubei and Hunan provinces—which account for nearly 40%

Biodiversity as a Dominant Force in Shaping Ethnic Music Styles 生物多样性:塑造民族音乐风格的主导力量
Integrative Conservation, Volume 5, Issue 2, Page 236-245, June 2026.Our findings show that plant, bird, and mammal diversity considerably shape musical features such as vocal range and ornamental sounds, more so than geography or lifestyle. Our study provides the first empirical evidence linking biodiversity to ethnic music styles. Protecting biodiversity, the musical and cultural will be protected.
