Satellite–Derived Topography and Morphometry for VHR Coastal Habitat Mapping: The Pleiades–1 Tri–Stereo Enhancement
leiades–1 photogrammetry RSP topography classification maximum likelihood landscape
2023/12/4
The evolution of the coastal fringe is closely linked to the impact of climate change, specifically increases in sea level and storm intensity. The anthropic pressure that is inflicted on these fragil...
Modelling of the reef benthic habitat distribution within the Cabrera National Park (Western Mediterranean Sea)
GIS bathymetry habitats mapping Mediterranean
2023/11/30
Habitat spatial distribution is essential to know where to focus the protection of the seafloor resources. In this work, the bathymetry and backscatter seabed data show the importance of remote sensin...
WETLAND CLASSIFICATION FOR BLACK DUCK HABITAT MANAGEMENT USING COMBINED POLARIMETRIC RADARSAT 2 AND SPOT IMAGERY
Wetlands Synthetic Aperture Radar Polarimetric data Decomposition Classification
2018/5/16
The black duck population has decreased significantly due to loss of its breeding habitat. Wetlands are an important feature that relates to habitat management and requires monitoring. Synthetic Apert...

2015/12/28
Generally, investigation for protection of the wildlife is difficult because it takes much work and time, and frequent monitoring.Therefore, studies of monitoring with remote sensing and GIS were carr...
The Use of Remote Sensing Data for Habitat Fragmentation and Herpetological Biodiversity Studies in the Mediterranean Basin (BIOFRAG)
RS-GIS Modeling Biodiversity Species Distribution Environmental Parameters
2015/12/18
The aim of the BIOFRAG project is to understand how environmental factors explain herpetological biodiversity in the Mediterranean Basin, with a focus on to identify management options by anticipating...
Open and closed seascapes: Where does habitat patchiness create populations with high fractions of self-recruitment?
coral reef seascapes dispersal
2015/12/11
Which populations are replenished primarily by immigrants (open) and which
by local production (closed) remains an important question for management with implications
for response to exploitation, p...
Many corals host thermally resistant symbionts in high-temperature habitat
Symbiodinium Host–symbiont specifi city
2015/12/11
Physiologically distinct lines of dinoflagellate
symbionts, Symbiodinium spp., may confer distinct thermal
tolerance thresholds on their host corals. Therefore, if a
coral can alternately hos...
Whole-Genome Positive Selection and Habitat-Driven Evolution in a Shallow and a Deep-Sea Urchin
positive selection dN/dS
2015/12/11
Comparisons of genomic sequence between divergent species can provide insight into the action of natural
selection across many distinct classes of proteins. Here, we examine the extent of positive se...
Modeling the spread of the Argentine ant into natural areas: Habitat suitability and spread from neighboring sites
Invasion model Grid-based model
2015/12/10
To predict a fine-scale invasion of Argentine ants (Linepithema humile) into a natural area from the surrounding suburban matrix, we introduce a grid-based invasion model, similar to a cellular ...

Salmonid Electronic tag Geolocation Movement Water temperature Depth Marine Ocean Freshwater
2015/11/16
Acoustic and geolocating archival tags were deployed on steelhead kelts to study their post-spawning migrations, diving behavior and thermal habitat.Fourteen reconditioned steelhead kelts were surgica...
Stable isotope analysis of vertebrae reveals ontogenetic changes in habitat in an endothermic pelagic shark
stable isotope analysis elasmobranch ontogenetic shift satellite tagging stable isotope mixing model
2015/11/16
Ontogenetic changes in habitat are driven by shifting life-history requirements and play an important role in population dynamics. However, large portions of the life history of many pelagic species a...
