Species distribution modelling
8 important questions on Species distribution modelling
What is a resource selection function?
- Species use certain habitats (resources) more often than other habitats. These habitats are probably important for survival.

How do you determine if a species is absent (0)?
- Direct and indirect observations
- Random points (excluding the locations where the species has been observed)
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
What is the spatial bias?
What is the temporal bias?
What is the Maximum Entropy Approach?
- Presence-only data
- Pseudo-absence data
- Occurrence is location (X-coord, Y-coord)
- Environmental variables from whole area
What is the input for MaxEnt?
- Presence-only data (o)
- (Random) background locations (pseudo-absences) (x)
- Environmental variables from each location
What is the output from MaxEnt?
- Relative probability of species in every location
- Importance of environmental variables in explaining distribution

- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
