This week in research #140

Here's what caught my eye in research over the past week (another quiet week, it seems):

• Higney et al. (open access) estimate the marginal value of bird song, using a choice experiment with a 'simulated soundscape'

Also new from the Waikato working papers series:

• Gibson, Boe-Gibson, and Scrimgeour use night-time lights to measure the urban expansion and contraction of urban areas in New Zealand, finding that rapid expansion is concentrated in commuter towns surrounding major cities and amenity-oriented settlements, while some smaller towns experience contraction associated with economic restructuring and changing locational advantages
