Introduction
My research focuses on evaluating population-level attributes to detect the responses of natural and managed systems to ongoing environmental changes. I combine data-driven empirical approaches with theoretical modeling to assess the viability of threatened and endangered plant populations as well as the impact of invasive species. I am also interested in the ecology of animal-plant interactions and the reproductive biology and the population ecology of tropical plants.

A fundamental goal in invasion ecology is to identify and understand the factors explaining why some alien species become invasive when others fail. In this study we gathered data on taxonomy, invasive status, invasion history, geographic distribution, and biological and ecological traits of 1,032 alien plant species occurring on different habitats...
Article
The negative impact of invasive plants on native species has been well documented, but little is known about the specific role that invaders play on the population decline of native species. Here we used demographic models to evaluate how the alien grass Megathyrsus maximus affects the population dynamics of the native cactus Harrisia portoricensis...

The level of invasion (number or proportion of invasive species) in a given area depends on features of the invaded community, propagule pressure, and climate. In this study, we assess the invasive flora of nine islands in the West Indies to identify invasion patterns and evaluate whether invasive species diversity is related to geographical, ecolo...
Article
Full-text available
Aim Understanding the factors driving the diversity of alien and native species on islands is crucial for predicting the spread of alien species and for proposing management practices to protect the unique native biodiversity that often occurs in insular ecosystems. The main objective of this study was to evaluate whether native and alien plant spe...

C. grandiflora is a highly invasive weed in semi-arid natural ecosystems, especially dry or monsoonal rainforest. It has the potential to spread much further, especially in Australia where it poses a threat to national parks.

Native flora and fauna of Puerto Rico have a long biogeographic connection to South America. Theory and empirical evidence suggest that islands, particularly those distantly isolated from the mainland, should be more susceptible to naturalizations and invasions of non-native species than continental areas. Anthropogenic disturbances can facilitate...
