Modelling habitats in karst landscape by integrating remote sensing and topography data

Open Geosciences, 2018
Field mapping is an accurate but also time consuming method of detailed mapping of habitat types. Levels of habitat types are usually hierarchically nested at several levels.

Fully convolutional neural networks applied to large-scale marine morphology mapping

Frontiers in Marine Science, 2023
In this study we applied for the first time Fully Convolutional Neural Networks (FCNNs) to a marine bathymetric dataset to derive morphological classes over the entire Irish continental shelf.

Mapping Habitat Structures of Endangered Open Grassland Species (E. aurinia) Using a Biotope Classification Based on Very High-Resolution Imagery

Remote Sensing
Analyzing habitat conditions and mapping habitat structures are crucial for monitoring ecosystems and implementing effective conservation measures, especially in the context of declining open grassland ecosystems in Europe.

SEABED MAPPING USING 3D SEISMIC DATA TO INVESTIGATE CONTINENTAL SLOPE MORPHOLOGY AT THE BRAZILIAN EQUATORIAL MARGIN

, 2022
The Brazilian Equatorial Margin (BEM) is a transform passive margin formed by the Gondwana break-up during the Early Cretaceous (Aptian-Albian) (Matos, 1999). Rifting created a series of rift sedimentary basins including the Potiguar Basin (POT) (Fig.1a)-

Multispectral Multibeam Echo Sounder Backscatter as a Tool for Improved Seafloor Characterization

Geosciences, 2019
The establishment of multibeam echosounders (MBES), as a mainstream tool in ocean mapping, has facilitated integrative approaches towards nautical charting, benthic habitat mapping, and seafloor geotechnical surveys. The combined acoustic response of the

Exploration in Mapping Kernel-Based Home Range Models from Remote Sensing Imagery with Conditional Adversarial Networks

Remote Sensing, 2018
Kernel-based home range models are widely-used to estimate animal habitats and develop conservation strategies. They provide a probabilistic measure of animal space use instead of assuming the uniform utilization within an outside boundary. However, this

Avidin is evolutionarily conserved in fish but dispensable for development and resistance against Streptococcus agalactiae in zebrafish

FEBS Open Bio, EarlyView.
The presence of biotin‐binding avidin proteins in fish and their biological significance are poorly characterized. We cataloged fish avidins and demonstrate that they are widely present and evolutionarily conserved. We created avd knockout zebrafish and show that zebavidin is dispensable for development and that resistance of avd knockout embryos in ...

Detection of Boulders in Side Scan Sonar Mosaics by a Neural Network

Geosciences, 2019
Boulders provide ecologically important hard grounds in shelf seas, and form protected habitats under the European Habitats Directive. Boulders on the seafloor can usually be recognized in backscatter mosaics due to a characteristic pattern of high ...
