Villagra, Cristian A.; Ramírez, Claudio C.; Niemeyer, Hermann M. (Academic Press, 2002)Under predation risk, prey may prioritize antipredator behaviours and sacrifice feeding. However, energetically constrained animals may choose to sacrifice or change antipredator responses and accept relatively greater ...

Ramírez, Claudio C.; Caballero, Paula P.; Niemeyer, Hermann M. (Kluwer Academic/Plenum Publishers, 1999)We hypothesized that aphids after previous exposure to hydroxamic acids (Hx), a family of secondary plant compounds deleterious to aphids, are able to reduce their subsequent exposure to them. This hypothesis was tested ...

Figueroa, Christian; Niemeyer, Hermann; Cabrera-Brandt, Marco; Briones, Lucia; Lavandero, Blas; Zúñiga Reinoso, Alvaro; Ramírez, Claudio (Wiley, 2018-07)The diversity and distribution of the genetic variation in forest phytophagous insect populations can be highly sensitive to forest fragmentation. This should be particularly evident for monophagous insects living on ...

Quiroz, Andrés; Fuentes-Contreras, Eduardo; Ramírez, Claudio C.; Russell, Graeme B.; Niemeyer, Hermann M. (Kluwer Academic/Plenum Publishers, 1999)Extractable metabolites from leaves (EM) and volatiles released from six Nothofagus species were analyzed by TLC and GC-MS, respectively. Aphids of the genus Neuquenaphis, closely associated to Nothofagus, were sampled on ...

Ramírez, Claudio C.; Niemeyer, Hermann M. (2000)It was hypothesized that (1) previous experience of aphids on a host plant leads to differences in their feeding behavior relative to aphids without previous experience on it and that (2) a change in the physiological state ...
