Microsatellite and Mitochondrial Markers Show Low Genetic Structure in the Elkhorn Coral of Puerto Rico
(External Scientific Advisory Committe (ESAC), 2009-11)Fine scale genetic structure of the coral Acropora palmata was investigated by sampling 9 reefs in Puerto Rico and 1 in the Bahamas as an out-group. Of a total of 276 samples, 201 had unique genotypes and the remaining 75 ... -
Modeling Species Dynamics to Predict Population Dynamics Examples from Recent Publications
(External Scientific Advisory Committe, 2009-11)Dormancy is common in many terrestrial orchids in southern Australia and other temperate environments. The difficulty for conservation and management when considering dormancy is ascertaining whether non-emergent plants ... -
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 ... -
Mycorrhizal specificity of the invasive orchid Oeceoclades maculata in Puerto Rico
(External Scientific Advisory Committe (ESAC), 2009-11)The terrestrial orchid Oeceoclades maculata is found throughout Puerto Rico. Originally from Africa, it has been called the most widespread orchid around the world. This success has been attributed to its tendency for ... -
Phylogeography and Conservation Genetics of Tabebuia heterophylla (DC.) Britton (Bignoniaceae)
(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 ... -
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 ... -
Pollen Reference Collection of Plants of Puerto Rico
(External Scientific Advisory Committe (ESAC), 2009-11)Pollen is produced by the male cone or flower organ (stamen), and represents the microgametophytic generation in spermatophytes. Pollen morphology has proved to be of significant taxonomicutility in different research ... -
Pollination Biology of Harrisia portoricensis (Cactaceae), an Endangered Caribbean Species
(External Scientific Advisory Committe (ESAC), 2009-11)Information on the breeding system of endangered plants is often useful piece of information for conservation and management of wild populations. This is so as the foraging behavior of the pollinators and the plant breeding ... -
Preliminary Study of the Soil Microbiology Associated to Isolated Dwarf Tree Species in the Coastal Plateu of Guánica Dry Forest
(External Scientific Advisory Committe (ESAC), 2009-11)Soil function and productivity depends on microbial communities for nutrient cycling, antagonistic effects and decomposition of organic matter among others. Mass and diversity of soil microbial communities depend on substrate ... -
Rapid assessment of Mona Island’s coral reefs following the 2005-2006 post-bleaching mass mortality event: Evidence of climate change impacts
(External Scientific Advisory Committe (ESAC), 2009-11)Mona Island, located nearly halfway between La Hispaniola and PR, is considered a unique and pristine natural wonder in the Caribbean. Its coral reef ecosystems are paramount for maintaining the meta-population connectivity ... -
Roadside Ménage à Trois: A Native Pest on an Exotic Orchid Weed Defended by Ants?
(External Scientific Advisory Committe (ESAC), 2009-11)The resource concentration hypothesis states that herbivores are more likely to find and remain on hosts that are growing in dense stands. Some areas in the Rio Abajo Reserve of Puerto Rico have dense populations of ... -
Seed rain in a removal experiment in a cactus-shrub area invaded by an exotic grass in Mona Island
(External Scientific Advisory Committe, 2009-11)As part of an experiment to test the effects of removal of an invasive species (Megathyrsus maximus) in cactus populations in the Eastern coastal area of Mona Island, we collected seed sand plant parts in tray traps, located ... -
Sensing climate change in an ephemeral coastal pond: implications to the conservation of biodiversity in a subtropical dry forest
(External Scientific Advisory Committe (ESAC), 2009-11)There is concern that climate change may reduce rainfall in the Caribbean and increase sea levels thus altering groundwater supplies and coastal habitats. The potential effects of rainfall reduction and sea level changes ... -
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 ... -
