Roots, Dean 2010 Journal Sierra Mazateca, Oaxaca, Mexico Oct. 23 Dana Lee, a former Berkeley student in my IB104 class, flew to DF on Oct. 21. Yesterday, we left and drove to Teotitlán del Camino, then turned off on the road to Huautla. We arrived at Puerto Ixtepec after dark and searched along roadbanks for ~30 min. It was pretty dry, and I found only a Grangeria mexicana crossing the road. We drove to Huautla to spend the night. This morning, we spent a while getting permission from the Comisariado de Bienes Comunales in San Gerónimo Tecóatl. We then drove to Plan de Cuadulope and turned south for ~1 km. We started searching under small rocks along the road, but the roadside had recently been scraped clean. We looked in the walls and under many loose rocks as well as in a large pile of very good rocks along the road. We then climbed up the hill W of the road and searched in logs in very disturbed oak forest for ~30 min. We spent about 2 hr total searching here, then drove to Puerto Ixtepec and turned S on a dirt road. We stopped 1.5 km from the highway and opened ~35 Armadillo (there were tons) in what may have been secondary oak forest. We got 1 adult Pseudoryzomys sulfureus, which looks very much like the specimen that I got in Aug. 2008 near Peña Verde, S.M. Papalo – I now think they are the same. Finally, we drove to the nearby microwave towers and searched in logs for h30 min but found nothing. The oak forest here was rather dry. We drove to Teotitlán, where the road to Oaxaca was blocked by protesters. We spent the night in Teotitlán.
