Biodegradability of Dissolved Organic Carbon in the Río Piedras Watershed, Puerto Rico
(External Scientific Advisory Committe (ESAC), 2009-11)Organic matter is classified in groups, and total organic carbon (TOC) is the sum of dissolved organic carbon (DOC) and particulate organic carbon (POC). DOC composes most of the TOC and therefore it is our main focus. Puerto ... -
Biodegradability of dissolved organic carbon in three tropical watersheds
(External Scientific Advisory Committe (ESAC), 2009-11)In rivers, the microbial loop explains how microbes oxidize DOC to obtain energy making carbon available to higher trophic levels in the river foodweb. DOC biodegradability, however, is variable depending on its source. ... -
Blind Alleys of Evolution
(External Scientific Advisory Committe (ESAC), 2009-11)Genetic diversity underlies evolutionary potential of species. The distribution and quantity of genetic diversity are profoundly influenced by population structure and breeding system. Strong population subdivision has ... -
Breeding System of Guaiacum sanctum(Zygophyllaceae). Tropical Plant Ecology and Evolution Laboratory
(2009-11)Plant breeding systems and the factors that regulate sexual systems in natural plant populations may influence the frequency and quality of reproductive events (Richards1997). Data on there productive biology and breeding ... -
Carbon Fates in Tropical Stratify Estuaries
(External Scientific Advisory Committe (ESAC), 2009-11)Estuaries are highly productive coastal ecotones. Influenced by tidal, wave, and wind actions that control water mixing. Estuaries recipients of allochthonous organic matter (OM). OM is processed and exported to ocean under ... -
Changes in structural characteristics of leaves as related to water availability from trees growing in the Costal Plateau of Guánica Dry Forest
(External Scientific Advisory Committe (ESAC), 2009-11)Trees in the Coastal Plateau of Guánica Dry Forest are growing under a combination of environmental stressors such as water, nutrient availability, salt spray, and wind that determine their capacity to grow and maintain ... -
Combined impacts of sea surface warming, local runoff pulses, and meso-scale Caribbean gyres on coral reef rehabilitation success: Lessons learned to cope with climate change
(External Scientific Advisory Committe (ESAC), 2009-11)Low-tech coral aquaculture methods have been successfully used in Culebra Island, PR, since year 2003 to propagate threatened staghorn coral (Acropora cervicornis). Harvested corals are being used through the Culebra Island ... -
Contributions of Sewage effluents to Nutrients, Discharge, and DOC in Streams in Puerto Rico
(External Scientific Advisory Committe, 2009-11)Some waste water treatment plants(WWTP) in Puerto Rico continuously discharge their effluents directly to streams. With urbanization, generation of sewage effluents increases and fluvial export of nutrients are expected ... -
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., ... -
Crime scene investigation of recreational marine fisheries: The impact of shore-based recreational fishing of Queen Conch (Strombus gigas) in Culebra Island, PR
(External Scientific Advisory Committe (ESAC), 2009-11)Queen conch (Strombus gigas) is one of the most significant edible benthic invertebrate species through the Caribbean, but its populations have largely declined through time. Its recreational fishery impact still remains ... -
Detecting Vertical Transfer of Antibiotic Resistance Genes in the Absence of Antibiotics
(External Scientific Advisory Committe (ESAC), 2009-11)Our hypothesis is that antibiotic resistance can be vertically transmitted between generations, in the absence of antibiotics. Mothers readily colonize their offspring with bacteria that have antibiotic resistance genes. To ... -
Development of Microsatellite Markers for Population Genetic Studies of Harrisia portoricensisand Related Species
(External Scientific Advisory Committe (ESAC), 2009-11)Harrisia portoricensis is a columnar cactus endemic to Puerto Rico. It was first collected and described from southern Puerto Rico, but urban and agricultural development extirpated these populations. At present, the species ... -
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 ... -
Ecophysiological evaluation of the invasive capacity of an exotic plant (Spathodea campanulata-tulipánafricano) in a secondary forest of Puerto Rico
(External Scientific Advisory Committe (ESAC), 2009-11)The purpose of this research is to evaluate the potential invasibility of Spathodeacampanulata (Africantulip) in a secondary forest at the University of Puerto Rico at Humacao. We intended to assess ecophysiological ... -
Effect of exotic grass Megathyrsus maximuson soil mites fauna in Mona Island Reserve
(External Scientific Advisory Committe (ESAC), 2009-11)Biological invasions alter ecosystem processes in invaded areas, there by causing functional as well as compositional change (D’Antonio and Vitousek,1992). In dominated sites, grasses can alter ecosystem processes from ... -
Effect of exotic grass, Megathyrsus maximus, on native biodiversity in Mona Island Reserve
(External Scientific Advisory Committe (ESAC), 2009-11)Species invasions are considered one of the leading causes of global biodiversity loss (Wonham,2005)and are the second cause of species endangerment in the United States(Brooksand Pyke, 2002. The African grass, Megathyrsus ... -
