Demographic consequences of chronic anthropogenic disturbance on three populations of the endangered globose cactus Coryphantha werdermannii

Portilla-Alonso, RM; Martorell-Delgado, Carlos (2011)

Cacti are thought to be highly vulnerable to chronic anthropogenic disturbance (CAD). To assess its effects, we modeled the dynamics of three populations of the endangered cactus Coryphantha werdermannii exposed to different ...
Identifying the impacts of chronic anthropogenic disturbance on two threatened cacti to provide guidelines for population-dynamics restoration

Ureta, C; Martorell-Delgado, Carlos (2009)

Species frequently have to be preserved in disturbed areas. Restoring their predisturbance population dynamics may increase their population growth rate (lambda) while preventing the development of vulnerable genetic- or ...
Species-specific disturbance tolerance, competition and positive interactions along an anthropogenic disturbance gradient

Villarreal-Barajas, T; Martorell-Delgado, Carlos (2009)

Question As it has been found that stress promotes positive interactions mediated by physical amelioration of the environment, is it possible that interactions may turn positive with increasing chronic anthropogenic ...
