Conserving insect assemblages in urban landscapes: accounting for species-specific responses and imperfect detection

Luis Mata's research

This post is a about a new paper in the Journal of Insect Conservation.

Using the El Maresme shire (north-eastern Spain) as the study area and heteropteran bugs as model organisms, my colleagues (Marta Goula & Amy Hahs) and I set out to explore the effects of urbanization on insects.

I was especially impressed by the large diversity of bugs species that we found in our survey. The field work yielded 142 different species of heteropteran bugs. Since the heteropteran bug gamma diversity of El Maresme is known to be  323 species1, we can estimate that our study collected detection and occupancy data for almost 45% of the heteropteran bug species known to the region. Among these species was the ash-grey leafbug Piesma maculatum (Laporte, 1833), a species that had not been seen in El…
