On 11 September 2014 I gave a talk about road ecology for DERSA in São Paulo, Brazil. DERSA is the state agency for roads in São Paulo state (44 million people). There were several journalists present, including from an engineering magazine "Revista O Empreiteiro" ("The Contractor Magazine"). http://www.oempreiteiro.com.br/Publicacoes/15240/O_fator_animal.aspx
