Comparing Freshwater eDNA With Conventional Survey Methods to Detect Vertebrate Biodiversity in a Malagasy Tropical Rainforest

Environmental DNA, Volume 8, Issue 3, May–June 2026.
This study compares the efficacy of conventional surveys of vertebrate taxa to eDNA metabarcoding of freshwater samples from a tropical rainforest ecosystem in the Makira Forest Protected Area (MFPA), Madagascar. We demonstrate high but taxa‐varying efficacy of eDNA metabarcoding detections, reinforcing its use as a complementary biodiversity survey ...

Seabed classification in the Gulf of Alaska from acoustic surveys using deep learning

Limnology and Oceanography: Methods, Volume 24, Issue 5, May 2026.
Abstract High‐resolution mapping of seafloor habitats has wide applications for fisheries, conservation efforts, offshore infrastructure planning, mineral extraction, and scientific modeling. This study leverages existing widespread single‐beam acoustic data and machine learning to create habitat maps for the Gulf of Alaska at a spatial resolution of ...

Rapidly declining seagrass meadows in Brazil: Findings from satellite imagery and local knowledge

People and Nature, Volume 8, Issue 5, Page 1155-1171, May 2026.
Abstract Due to the limitations of individual monitoring approaches, integrating social perceptions with multiple advanced technologies provides a new opportunity to gain a comprehensive understanding of ecosystem degradation. We combined historical aerial mapping, satellite imagery, semi‐structured interviews with local stakeholders, and a bilingual ...

Mapping River Bed Topography in Whitewater Rapids Using Bathymetric LiDAR

River Research and Applications, Volume 42, Issue 4, Page 886-900, May 2026.
ABSTRACT Bathymetric LiDAR captures river topography efficiently for clear and shallow water, but for mountain rivers, whitewater rapids still pose challenges. This study proposes a novel method to enable the extraction of bottom returns specifically in turbulent whitewater sections.
