Resumen:
In 2005, Gurvich et al. proposed that ??once a nonindigenous species has arrived to a new ecosystem and become established, the likelihood that it spreads, and thus becomes invasive, may depend on just one or very few characteristics, called ?triggering attributes? (TA). We propose that a TA is a vegetative or regenerative attribute discontinuously distributed in comparison to the resident community. This attribute allows the species to benefit from a resource that is permanently or temporarily unused by the resident community.?? ??The winter fruit phenology of two fleshy fruited invaders (P. angustifolia and Ligustrum lucidum) was proposed as an example of TA that would allow these two species to take advantage of a resource (bird dispersal) that resident fleshy-fruited species?whose fruits are ripe in summer and autumn?cannot tap during the winter??(Gurvich et al. 2016). We believe that the model they proposed is a very valuable one, and useful to identify special traits involved in plant invasion processes. In a recent response to an article that evaluates if a vegetative attribute behaves as a TA (Vergara-Tabares et al. 2015), Gurvich et al. (2016) expressed disagreement regarding the logic used to develop the experimental design and the main conclusions of the study. The arguments of Gurvich et al. (2016) demonstrate some misinterpretation of the study and its results, and we believe it deserves clarification.
