Melbourne Water bug database now available

We have worked with Melbourne Water to collate their collection of macroinvertebrate assemblage records from streams of the Greater Melbourne region over the last 25 years into a database, and have made it available and searchable on an open-access web interface (https://tools.thewerg.unimelb.edu.au/mwbugs/). This rich resource of biological information has been…

A data entry app for Australian stream macroinvertebrates

Sure, this might be a bit niche, but in preparation for the imminent release of a portal for Melbourne Water’s stream macroinvertebrate database, I’ve created a data-entry app for compiling macroinvertebrate assemblage data into a table that is suitable for entry into the database (and suitable for analysis on its…

A new year, a new server, a resolution of sorts

The desktop box that is urbanstreams.net is getting old. We are in the process of migrating the contents of this site to a more stable and secure location. The move has begun with our apps. Because he who is last will be first, the most recent app is the first…

The LUMaR tool

Walsh and Webb (2013) developed a new index of stream condition, LUMaR*, based on their distribution models of 60 families of macroinvertebrates across the Melbourne region.  The models allow prediction of the effects of loss (or gain) of forest cover and of conventionally drained urbanization on the occurrence of the 60 families….

A big step forward – escape from Optus

Happy days!  We are finally moving out of our rental house, meaning that we can at last part ways with Optus as an internet service provider.* So, with a new IP address, urbanstreams.net can finally drag itself out of a dark, unvisited corner of the internet, with a proper URL….
