Nuevo Proyecto: “Interacciones ecológicas como indicadoras de gestión en áreas naturales protegidas”

Este proyecto financiado por el Programa Iberoamericano de Ciencia y Tecnología para el Desarrollo (CYTED) y coordinado por el Profesor Rodrigo Medel (Universidad de Chile) aborda la gestión de las áreas naturales protegidas (ANPs en adelante) desde el dominio de las interacciones interespecíficas planta-animal.

A general framework for effectiveness concepts in mutualisms

A general framework for effectiveness concepts in mutualisms

A core interest in studies of mutualistic interactions is the ‘effectiveness’ of mutualists in providing benefits to their partners. In plant-animal mutualisms it is widely accepted that the total effect of a mutualist on its partner is estimated as (1) a ‘quantity’ component multiplied by (2) a ‘quality’ component, although the meanings of ‘effectiveness,’ ‘quantity,’ and ‘quality’ and which terms are applied to these metrics vary greatly across studies. In addition, a similar quantity × quality = total effect approach has not been applied to other types of mutualisms, although it could be informative. Lastly, when a total effect approach has been applied, it has invariably been from a phytocentric perspective, focussing on the effects of animal mutualists on their plant partner. This lack of a common framework of ‘effectiveness’ of mutualistic interactions limits generalisation and the development of a broader understanding of the ecology and evolution of mutualisms.

Hidden Extinctions: Losing plant diversity in Iberian arid zones as a consequence of the anthropic-mediated expansion of weedss

In this project, funded by the Fundación BBVA (PR17-ECO-0021), we evaluate the consequences of the expansion of weeds associated to human environments on the arid vegetation from the Iberian Peninsula. The specific goal is to check whether the presence of the ruderal species Moricandia arvensis is having a harmful effect on its three co-generic species endemic to arid habitats, namely, M. moricandioides, M. foetida and M. rytidocarpoides.
