Spatial analysis of foraging activity of the Polygynous Red Imported Fire Ant Solenopsis invicta (Hymenoptera: Formicidae).
(External Scientific Advisory Committe (ESAC), 2009-11)Densities of polygyne Solenopsis invicta are higher in the introduced range than the monogyne social form and this might be because the lack of intraspecific aggression, but the mechanisms of how polygyne colonies persist ... -
Spatial Distribution and Performance of Native and Invasive Ardisia (Myrsinaceae) Species in Puerto Rico: The anatomy of an invasion
(External Scientific Advisory Committe (ESAC), 2009-11)Establishing and spread of invasive species into new habitat is considered the second most significant threat to biodiversity worldwide, this is in part due to displacement and extinction of native species. However, the ... -
Star coral (Montastraea annularisspp. complex) population collapse: An unequivocal sign of climate change impacts in Caribbean coral reefs Raisa
(External Scientific Advisory Committe (ESAC), 2009-11)A catastrophic warming event occurred during 2005 throughout the northeastern Caribbean Sea that caused a mass coral bleaching event in Puerto Rico the was followed by an unprecedented mass mortality of the Montastraea ... -
Status of viruses causing symptoms in cucurbits in Puerto Rico
(External Scientific Advisory Committe (ESAC), 2009-11)Cucurbits provide important basic ingredients for the Caribbean diet. Pumpkins are the second most important vegetable crop in terms of revenue generated in Puerto Rico. Virus and severe virus vector outbreaks are a frequent ... -

(External Scientific Advisory Committe (ESAC), 2009-11)To compare the exotic freshwater fish community and determine similarity patterns among several reservoirs. -
The Laboratory of Terrestrial Ecology and Ecophysiology at the University of Puerto Rico at Humacao
(External Scientific Advisory Committe (ESAC), 2009-11)To serve our community of undergraduate students, providing opportunities to participate in high quality research projects in the field of ecology. To develop interdisciplinary research and educational projects with members ... -
There goes the neighborhood: Reproductive success of Bletia patula when Spathoglottis plicata moves in
(External Scientific Advisory Committe (ESAC), 2009-11)Naturalized exotic species are homogenizing the earth’s biota and are increasing densities of pests in newly colonized areas. When exotics change ecosystems and affect native species, then they are invasive. Do high density ... -

Water Use Efficiency by Mangroves in The Guánica Dry Forest Reserve
(External Scientific Advisory Committe (ESAC), 2009-11)It is important to understand and study the different adaptations and responses of plants changes in climate, especially, those living in arid environments where high temperatures, low precipitation, soil depth, ... -
Where is the water coming from in Puerto Rico? Temporal and regional dynamics of precipitation in Puerto Rico as determinated by isotopic signatures of ð ¹⁸O and ð D.
(External Scientific Advisory Committe (ESAC), 2009-11)The annual amount, pattern, frequency and intensity of precipitation determine ecosystem dynamics and ground water recharge. Global climate change and regional climate variability are influencing precipitation dynamics in ...
