Frugivory in Puerto Rican Anolis lizards and its possible effects on seed dispersal in tropical dry and moist forests on karst
(External Scientific Advisory Committe (ESAC), 2009-11)Feeding is an important component in consumer-resource interactions of population-community ecology and in energy and nutrient transfers of ecosystems ecology (Bengtsson 1998). Food webs are used to describe the complexity ... -
Coral reef ecosystem collapse in Puerto Rico: Combined impacts of long-term local anthropogenic factors and climate change
(External Scientific Advisory Committe (ASEC), 2009-11)Coral reefs are under increasing threats that have undermined their resistance ability to disturbance, their ecological functions and their ecosystem resilience. A combination of long-term impacts by natural factors (i.e., ... -

(External Scientific Advisory Committe (ESAC), 2009-11)Mona Island is a Natural Reserve under the management of the Department of Natural Environment Resources (DNER). Mona Island iguana (Cyclura cornuta stejnegeri), is an endemic reptile species of this region which is ... -
Algorithm to access and analyze environmental data from public web images without accessing a database
(External Scientific Advisory Committe (ESAC), 2009-11)Obtaining environmental data may require to access a database. But, what if we have only images available and not a database? We developed an algorithm, using Python™ programming language, and we could access public web ... -
Diversity of fungi in the Hoatzin crop: an 18S rDNA-based approach
(Extenal Scientific Advisory Committe (ESAC), 2009-11)The Hoatzin is a unique South American herbivorous bird and the smallest vertebrate to have a fermentative crop, similar to the cow rumen. Like bacteria, fungi play an important role in ... -
Plant-Insect Interactions: Do herbivores restrict the reproductive output of Spathoglottis plicata?
(External Scientific Advisory Committe (ESAC), 2009-11)Many exotic plants have naturalized in Puerto Rico, some of which may pose a threat to native species. One such exotic is Spathoglottis plicata, an orchid native to Southeast Asia. Popular as an ornamental, this orchid has ... -
Location Drone Congregation Areas (DCA) or honey bee mating congregation
(External Scientific Advisory Committe (ESAC), 2009-11)Honey bee mating at 30 meters above ground and 12 miles/hour make studies on conservation, hybridization, and mating behavior difficult. Establishing a reliable set of criteria that could aid in finding DCAs are important ... -
Arthropod diversity in caves with moderate and high anthropogenic presence.
(External Scientific Advisory Committe (ESAC), 2009-11)Extensive diversity of organisms are found in subterranean habitats varying in degrees of permanence and residence (Culver 2009). Cave organisms are classified as trogloxenes, those that are accidental and temporal subterranean ... -

(External Scientific Advisory Committe (ESAC), 2009-11)Tabebuia heterophylla (DC.) Britton (Bignoniaceae) is a charismatic neotropical tree species known for its attractive flower sand economically valuable wood. The species is considered to have an extremely wide distribution ... -
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 ... -
Molecular typification of bacterial isolates from the hoatzin crop (Opisthocomus hoazin)
(External Scientific Advisory Committe (ESAC), 2009-11)The Hoatzin is one of the world’s few obligate folivorous birds inhabiting the riverine forests of northern South America. It is the smallest vertebrate to have an enlarged foregut, in which plant structural carbohydrates ... -

Leaf litter decomposition in tropical and temperate rainforests: teaching climate-driven ecosystem processes outside the science classroom.
(External Scientific Advisory Committe (ESAC), 2009-11)One of my goal as a future teacher is to motivate students to better understand the environment and the the natural processes that regulates the ecosystem functionality. One way to accomplish this is by teaching ecosystem ... -
Factors affecting seed germination and seedling establishment of Harrisia portoricensis (Cactaceae) in Mona Island
(External Scientific Advisory Committe (ESAC), 2009-11)Germination, establishment, and survival of young plants appear to be the most critical phases in the life cycle of cacti (Godínez-Alvarez et al. 2003). Thus, understand factors affecting processes of germination and ... -
