Recent Evolution (1956–2017) of Rodas Beach on the Cíes Islands, Galicia, NW Spain
Journal of Marine Science and Engineering, 2019 Sedimentary coastal areas change rapidly and are economically and environmentally important. This research focuses on determining the extent to which natural dynamics and human activity have contributed to visible changes on Rodas, Cíes Islands in ...

Monitoring sediment transfer processes on the desert margin [PDF]
LANDSAT Thematic Mapper and Multispectral Scanner data have been used to construct change detection images for three playas in south-central Tunisia. Change detection images have been used to analyze changes in surface reflectance and absorption between ...

Geomorphic change detection in Gadria-Strimm and Moscardo catchments, Italy
, 2015 Methods devoted to the assessment of geomorphic changes can be used to identify geomorphologically unstable areas, to quantify processes intensity, and to compute sediment budgets. Digital elevation models (DEMs) built from repeated topographic surveys can be used to produce DEM of Difference (DoD) maps whose analysis allows to study morphological ...

Scenarios and strategies for future‐proofing ecosystem management under climatic novelty
Conservation Biology, EarlyView.Abstract Climate change is driving unprecedented declines in dominant, habitat‐forming foundation species across marine and terrestrial ecosystems globally. As climatic novelty becomes the norm, ecosystem reassembly will become increasingly common. Predicting and understanding these transitions, and their implications for future ecosystem functioning ...

, 2021 Repeated topographic surveys enable the creation of multi-temporal Digital Elevation Models (DEMs) and allow the derivation of DEM of Difference (DoD) that permits assessing geomorphic changes and estimates area and volume of changes through time. This study analysed three high-resolution DEMs (1 m resolution) in order to assess topographic changes ...

Journal of Fish Biology, EarlyView.Abstract Southern Africa is a region denoted by both high levels of fish diversity, some of it cryptic and unrecognised by current taxonomy, and severely threatened freshwater ecosystems. The Waterberg, a key aquatic ecoregion of the greater Limpopo River basin in South Africa, represents an area with high terrestrial conservation value but is lacking ...

Journal of Fish Biology, EarlyView.Abstract Quantifying the potential effects of climate change on juvenile salmonid body length at a large spatiotemporal scale is challenging given the multitude of biological processes and methodological constraints. In the present work, we analysed potential changes in size‐at‐age of juvenile Atlantic salmon cohorts over the past 50 years in the ...

Glaciation of northwestern Wyoming interpreted from ERTS-1 [PDF]
Analysis of ERTS Imagery has shown a number of alpine glacial features can be recognized and mapped successfully. Although the Wyoming mountains are generally regarded as the type locality for Rocky Mountain glaciation some areas have not been studied ...
