Current freshwater conservation efforts fall short in effectively protecting freshwater biodiversity. Acknowledging the challenge in freshwater conservation management, further assessments are needed regarding the efficiency of conservation planning. We aim to analyze global, systematic conservation planning networks given the key features habitat and biodiversity to (i) highlight areas of irrepl…
The Hydography90m dataset » Click here for the visualization « We used the MERIT Hydro Digital Elevation Model at 3 arc-sec (∼90 m at the equator) to derive a globally seamless, standardised hydrographic network, the “Hydrography90m”, with corresponding stream topographic and topologicalinformation. A central feature of the network is the minimal upstream contributing area, i.e. flow accumulation…
Freshwater ecosystems are among the most biodiverse and the most important providers of services to humans globally. Unfortunately, these ecosystems are also among the most threatened in the world. In Cuba, the main threats to freshwater ecosystems are climate change and habitat loss and fragmentation induced by land use/land cover change (LULC). Cuba’s National System of Protected Areas (in shor…
The Geomorphho90m dataset » Click here for the visualization « Topographical relief comprises the vertical and horizontal variations of the Earth’s terrain and drives processes in geomorphology, biogeography, climatology, hydrology and ecology. Its characterisation and assessment, through geomorphometry and feature extraction, is fundamental to numerous environmental modelling and simulation anal…
This tutorial shows you how to calculate stream-specific freshwater variables by relating the upstream e.g. land cover to any given downstream location using the GRASS GIS add-ons r.stream.watersheds & r.stream.variables . The original 1km data and publication are available here - see also the original code from spatial-ecology.net . This example contains the following steps: Download an exemplar…
