Abstract: Resumen Los cactus globulares son el grupo de cactáceas en mayor riesgo de extinción en el Ecuador Continental. Melocactus bellavistensis, se encuentra distribuido en un valle seco interandino en la provincia de Loja y actualmente se encuentra listado en la categoría de Datos Insuficientes (DD) por la UICN. La otra especie, M. peruvianus se conoce solo en dos localidades confirmadas en Huaquillas (El Oro), cerca de la frontera con Perú y está considerada como extinta en el Ecuador. Se reporta un nuevo registro… Show more

“…Population structure and habitat. -The assessed population shows a low density of individuals compared to other cactus species (Texeira et al 2004, Ceroni et al 2007, Castañeda-Romero et al 2016, Zepeda et al 2017, Loaiza and Molina-Moreira 2019, which may be related to the characteristics of the habitat where they are established and the strategies of the plant itself for its survival. There is probably competition between members of the population to obtain water and the distance between individuals has to be sufficient, so that each one receives what is necessary.…”

“…Considering our results, the main efforts must be focused on conserving isolated populations outside the conservation units and in the private areas, since they shelter most abundant populations and are more susceptible to anthropic threats. Meanwhile, it is important to develop strategies to enhance the connectivity between population patches, reducing the chances of local extinction and allowing dispersion and recolonization of empty areas, as well as for conservation measures such as species reintroduction and local management (Hanski & Gaggiotti 2004;Salazar & Moreira 2019).…”
