Journal Article
urbanization on birds. PLoS ONE, 12(e01744), https://doi.org/10.1371/journal.pone.0174484

The effects of streets on biodiversity is an important aspect of urban ecology, but it has been
neglected worldwide. Several vegetation attributes (e.g. street tree density and diversity)
have important effects on biodiversity and ecological proces... Read More about Street trees reduce the negative effects of urbanization on birds.

Evaluating patterns of human–reptile conflicts in an urban environment (2016)
Journal Article
environment. Wildlife Research, 42(7), https://doi.org/10.1071/WR15143

Context. Reptiles, especially snakes, can cause a fear reaction in the public and are, therefore, a good model to examine human–wildlife conflicts. Human city dwellers often respond to the presence of snakes or other reptiles by calling out the respo... Read More about Evaluating patterns of human–reptile conflicts in an urban environment.
