Drosophila as a versatile in vivo testbed for nanomaterial toxicity assessment.
(2012)
Dramatic advances in nanomaterials synthesis and characterization provide promising possibilities for biomedical applications. Consequently, there is a growing demand for well- characterized, low cost toxicity assays for ...
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 ...
Dinámica y distribución de comunidades bacterianas en dos biorreactores de lodos activados en plantas de tratamiento de aguas residuales domésticas
(2009)
Biological wastewater treatment systems are recognized today as the most common biotechnological application in the World. But despite of their widely distributed use, there is a very limited knowledge of their distinctive ...
Generation of large-insert metagenomic libraries from subtropical hypersaline microbial mats and their screening for antibiotic resistance
(2012)
Most of the microbial diversity in an environment cannot be studied through laboratory standard media culture methods. For this, an emerging science, coined “Metagenomics”, has been developed as an effort to access the ...
Procedencia del ADN mitocondrial euroasiático occidental en Puerto Rico
(2009)
This study analyzed 102 mtDNA control region sequences with the objective of classifying them into sub-haplogroups and estimating their continental origin. Principal component analysis of the western Eurasian sub-haplogroups ...
Vocal interactions and song performance in Adelaide’s warbler (Setophaga adelaidae)
(2015)
Vocal interactions are very common in songbirds. Song-type matching is a kind of vocal interaction in which an individual matches the song-type that his neighbor sang. Traditionally, song-type matching has been considered ...
Phylogenetic and taxonomical characterization of microbial populations putatively capable of autotrophic ammonia oxidation from marine, saline and hypersaline environments at the Cabo Rojo Salterns, Puerto Rico
(2016)
Autotrophic ammonia oxidation has been studied over the years and several enzymes involved in this metabolism have been identified. This metabolism has been detected in several environments, but there are no reports of it ...
Hyphomycetes associated with submerged bamboo leaves (Bambusa vulgaris) in Quebrada de Oro in Mayagüez, Puerto Rico.
(2008)
Leaf litter is a major source of nutrients for heterotrophic organisms in aquatic ecosystems in which microorganisms contribute significantly to the breakdown process of leaf litter. Fungi as aquatic hyphomycetes are ...
Monitoring the diversity and species distribution of enterococci at a subtropical seawater system in Mayagüez, Puerto Rico
(2015)
Enterococci are an important group of bacteria used as fecal indicator by the United States Environmental Protection Agency (USEPA) to evaluate the quality of recreational waters. Specifically, a beach is “contaminated” ...
Efecto de las variaciones en la radiación fotosintética activa (“PAR”) en el contenido nutricional del mirto, Murraya exotica (Rutaceae), y su habilidad de sustentar a Diaphorina citri (Hemiptera: Liviidae), vector de la enfermedad de enverdecimiento de cítricos
(2015)
The Asian citrus psyllid, Diaphorina citri Kuwayama (Hemimptera: Liviidae), is an important pest of citrus because it transmits the bacteria (Candidactus Liberibacter spp.) that has been implicated in causing Huanglongbing ...
