There are several tutorials and articles out there, but this is what I did when I needed to plot a bathymetry profile across a set of points.
What was supposed to be a weekend counting shorebirds at Rangitoto and Motutapu islands turned into a little lizard survey by surprise.
The breeding season 2018-2019 is over and it looks like it hasn't been bad for the west coast. As far as I know a total of 10 chicks have successfully fledged but I expect the final count to be announced at the Auckland dotterel forum next April.
One of my favorite papers last year was "Aquatic Ecological Assessment" taught by Dr. Kevin Simon. As part of this course I did an analysis using data collected by the Auckland Council from a set of freshwater streams in the Auckland region. The report makes use of several macroinvertebrate biotic indices: macroinvertebrate community index (MCI), semi-quantitative macroinvertebrate community index (SQMCI), taxa richness (TR) and the percentage of Ephemeroptera (mayfly), Plecoptera (stonefly) and Trichoptera (caddisfly) (%EPT). I used R to perform all the calculations and to generate all the graphs and plots included in the analysis.
Non-metric multidimensional scaling (NMDS) is a technique often used to find similarities and similarities between communities composition. As a part of a broader analysis I wrote to assess the ecological integrity of a set of freshwater streams in the Auckland region, I used NMDS (using R) to compare macroinvertebrate communities composition among the studied streams.
Someone (no idea who!) nominated my mate Sean and I for a "Love your place" award. We were nominated under the category of "Kahikatea" for our work with the NZ dotterel at Piha. According to Ecomatters, the organisers of the event, the Kahikate award is given to an outstanding individual volunteer taking action on a local environmental issue.
