Habitat karakterisering van de Nederlandse Kustwateren. Deel 2: Fysische doelvariabelen

Het project Watersysteemverkenningen (WSV) levert objectieve en kwantitatieve informatie over de fysische, chemische en biologische toestand en het gebruik van verschillende watersystemen in verleden, heden en toekomst. Met behulp van deze informatie ontstaat inzicht in het functioneren van de Nederlandse watersystemen. In dit WSV-rapport wordt...

A practical method for quantification of impact of environmental changes to coastal biotopes

Based on the available data from literature, field observations and model results, the present study aims at achieving progress in the prediction of changes caused by environmental changes. For this a case study has been executed representing a macro-tidal site on the South-East coast of the U.K., the Elmer area

Assessment of direct and indirect effects of breakwater design on species assemblages in soft bottom habitats

Results of sampling at Cubelles (Catalunya, Spain), Elmer (Wessex, UK) and Lido di Dante (Italy).

Identification of the impact time-courses on surrounding assemblages

The aim of these studies were to analyse the extension of the area of influence of a low crested structure on the surrounding soft bottoms and on their infaunal assemblages. For this purpose, a new sampling design allowing to collect samples at a successive distance from the low crested structure have been adopted by the different teams, in...

Zeezoogdieren in de Westerschelde: Knelpunten en kansen

AANTALLEN EEN SCHIM VAN VROEGER Rond 1900 kwamen in de Westerschelde ca. 1000 Gewone Zeehonden (6000-11 000 in het hele Deltagebied) en honderden Bruinvissen voor. Tegenwoordig is het aantal Zeehonden beperkt tot ca. 50 (ca. 150 in de Delta) en komt de Bruinvis slechts sporadisch, maar in toenemende mate, voor. Er zijn tot op heden nog 18 andere...

Fish utilisation of managed realignments

One area of ecological benefit not yet fully evaluated in European waters is the utilisation of restored saltmarsh habitats by fish species. This study examines the utilisation of managed realignments and relic saltmarsh by fish species. Factors affecting habitat heterogeneity and fish populations are discussed, and recommendations are made with...

Zoute wateren EcotopenStelsel (ZES.1) / A Dutch Ecotope System for Coastal Water (ZES.1)

THIS ENTRY CONTAINS BOTH A DUTCH AND ENGLISH VERSION OF THE REPORT. SCROLL DOWN FOR THE ENGLISH SUMMARY. SAMENVATTING Het Zoute wateren EcotopenStelsel (ZES.1) is een instrument waarmee het potentiële voorkomen van habitats van de bodem van brakke en zoute Rijkswateren in kaart kan worden gebracht, voorspeld kan worden en vergeleken kan worden...

Affordance and behavior setting: A multi-level ecological perspective in the study of the meaning of habitat

Spatial and temporal variations' of characidae habitat, case study in Abras de Mantequilla wetland, Ecuador

A central component of predictive ecology in wetlands is the analysis of species distribution as a function of their biotic and abiotic environment. This analysis is normally used by decision-makers in biodiversity conservation, species monitoring and environmental planning, among others. Habitat suitability modelling is a major component of the...

Design-to-Robotic-Production of Underground Habitats on Mars

In order for off-Earth top surface structures built from regolith to protect astronauts from radiation, they need to be several meters thick. Technical University Delft (TUD) proposes to excavate into the ground to create subsurface habitats. By excavating, not only can natural protection from radiation be achieved but also thermal insulation,...

3D Habitat Mapping Using High-Resolution Optical Satellite and Lidar Data

Remote sensing datasets are great resources to map habitat types. In this study, 3D habitat maps were generated using high-resolution multispectral imagery and a LiDAR-derived digital surface model (DSM). Two study areas in the United Kingdom (UK) were selected to investigate the potential of the developed models in habitat classification. The...

Special Issue: Infraestructuras ocultas que apoyan los procesos migratorios en América del Sur

El desplazamiento masivo de la población en América Latina ha creado corredores de movilidad humanitaria en todo el continente y, en consecuencia, un territorio de larga tradición de desplazamiento forzado, donde miles de migrantes legales o ilegales, nacionales e internacionales se mueven cada día. En ese sentido, el primer interrogante que...
