Biodiversity data
- ocean depth, temp, water chemistry, solar radiation
- terrestrial temps, first freeze, etc.
- location data and changes over time for lots of species
- lots of people recording observations
How were these data collected?
- Inconsistancies in what’s recorded
- eg. sometimes seeing dog or cat
- how often do we record human
- how easy is it to see something hard to see
- how easy is it to overlook the obvious
- Some data is collected by non-scientists, some by scientists
- Data is often volunteered - where ever these people are
- ebird, inaturalist
- not totally reliable
- Data may be collected systematically
- Aquamaps - research studies - locations of species
- Aquamaps - ocean depth, temperature, physical characteristics
Are there any ethical concerns about the collection or use of these data?
- 1st world consumerism and impacts on 3rd world countries with high biodiversity
If there’s a model how is it constructed?
- Think about what’s recorded - how data is collected
- Aquamaps - predictive model of where a species might be
- make correlations in known areas for known data
- use correlations to predict response variable (# or probability or diversity) in unknown areas
- model change over time of particular species
- find predictive variables
