Relación entre los principales linajes Indígenas del ADN Mitocondrial en las Islas de Puerto Rico y República Dominicana
(2014)
It is well known that indigenous mitochondrial haplogroups A and C are predominant in the Dominican Republic and Puerto Rico. Medium networks built of sequences of the hypervariable regions of mtDNA have identified 13 ...
Tracing maternal Amerindian ancestry in the Aruban population through mtDNA sequencing
(2011)
As part of a study about pre-Colombian female migrations in the Caribbean, the mitochondrial DNA of the modern Aruban population was studied. The main objective was to identify the haplotypes in the Amerindian haplogroups ...
Characterization and detection by In situ gene amplification of marine denitrifying bacteria
(2003)
Recent studies suggest that the oceanic nitrogen budget is unbalanced, primarily
due to a high nitrogen removal in contrast to the fixation rate. This imbalance likely
results from denitrification activity in continental ...
Population ecology and reproductive behavior of the endangered Buxus vahlii Baillon (Buxaceae)
(2001)
Buxus vahlii Baillon is an endangered plant species endemic to Puerto Rico and St.
Croix (USVI). There are six known populations, four in Puerto Rico (Rincón, Isabela, two
in Bayamón) and two in St. Croix (Frederiksted ...
Quantification of the transcriptional activity of genes associated with cyanogenesis in Cassava (Manihot esculenta Crantz)
(2008)
Cassava has cyanogenic glycosides in its roots and leaves. These compounds function in plants as protective agents against herbivores as well as the translocable form of reduced nitrogen. The genes involved in the cyanogenic ...
Lead bioaccumulation by three tropical plant species
(2006)
Previous studies indicate that fast growing plants with high biomass could be employed for the remediation of lead (Pb) contaminated sites. Phytoextraction of Pb in a contaminated substrate was evaluated. To evaluate a ...
Endophytic fungi associated with the black mangrove Avicennia germinans in Cabo Rojo, Puerto Rico: Their antimicrobial potential
(2018-05)
The search for new antimicrobial compounds has been of great interest in recent years. These compounds are naturally produced by microorganisms including endophytic fungi isolated from mangroves. This study focuses on ...
Genetic Variation in the African Mitochondrial Haplogroup L3e in Puerto Rico
(2012)
This study aims to clarify the uncertainties of the African maternal origin of the Puerto Rico modern population that occurred during the slave trade. Haplogroup L3e was chosen for this study because it combines the ...
Composición y abundancia de las algas bénticas de cinco sistemas lóticos de Puerto Rico
(2007)
Benthic algal communities are often the dominant primary producers and important energy
source o higher trophic levels in rivers and streams. The composition and abundance of benthic
algae and relationships with ...
Catastro de hongos endofitos miceliales cultivables en hojas de la hierba marina Thalassia testudinum en playa Buyé, Cabo Rojo, Puerto Rico
(2006)
Endophytic fungi live inside plant tissues without any external manifestation. As reported previously, they play an important role in the vegetal tissues they inhabit. A study of the fungal endophytes of Thalassia testudinum ...
