The effects of the nanotopography of titanium surfaces on osteoblast adhesion and differentiation
(2013)
The principal problem in current orthopedic implants is their loosening due to poor osseointegration. Many efforts have been made to modify the surface composition and topography of titanium alloy implants to attain improved ...
Detection of integron-encoded integrases in environments with moderate anthropogenic impact from Puerto Rico
(2012)
Integrons are genetic elements with a site-specific recombination system which includes an integrase (IntI) capable of capturing and expressing promoterless, circular DNA molecules known as gene cassettes. Although integrons ...
Understory Plant Communities in the Surroundings of the Joyuda Lagoon, Puerto Rico
(2012)
Studies focused on the distribution of understory species associated with mangrove forests are very scarce. This research provides a detailed description of the understory community and their environmental requirements at ...
Function of song type matching in Adelaide’s Warbler (Setophaga adelaidae) in Cabo Rojo Wildlife Refuge (Cabo Rojo, Puerto Rico)
(2013)
Many species of birds sing the same song-type that a neighbor has just sung, a behavior known as song-type matching. Song-type matching has long been considered a signal of aggressive intent, but recent experiments fail ...
The use of two heterologous hosts for the study of virulence of Cryptococcus neoformans/gattii from Puerto Rico
(2013)
Cryptococcus neoformans (C. neoformans) and Cryptococcus gattii (C. gattii) are encapsulated, pathogenic yeasts, belonging to the Basidiomycota. They infect immune-compromised and immune-competent individuals respectively. ...
Predicting reproductive success in captive Puerto Rican parrots (Amazona vittata)
(2013)
The productivity of captive breeding programs can limit efforts to restore endangered species. The ability to accurately predict which captive pairs will breed successfully improves breeding productivity by allowing managers ...
Biogeography of copper-rich soil microbial communities associated with Gleichenella pectinata and Sticherus bifidus at Bosque del Pueblo (Adjuntas, PR) and Bosque Estatal de Maricao (Sabana Grande, PR)
(2010)
The biogeography of microbial communities in tropical environment is poorly understood. Recent works in soil microbial ecology have focused on cataloging the diversity of soil bacteria, but few of them have documented how ...
Its-5.8S-rDNA region and disease severity comparison of Rhizoctonia solani Anastomosis groups isolated from common bean (Phaseolus vulgaris L.) at Isabela, Puerto Rico
(2010)
Rhizoctonia solani is a widespread soilborne pathogen of common bean (Phaseolus vulgaris L.). This major pathogen is a species complex classified in 14 anastomosis groups (AG). Some AGs can cause web blight (WB), one of ...
Do novel Spathodea campanulata forests function as habitat for bryophytes? Analysis of diversity and establishment process
(2010)
In Puerto Rico an economic change has promoted the natural succession of secondary forests dominated by alien species such as Spathodea campanulata. These forests represent novel habitats in the Neotropics and appear to ...
Análisis arquitectónico de Buxus vahlii Baillon (Buxaceae) en dos ambientes diferentes de Puerto Rico
(2008)
The analysis of the architecture of Buxus vahlii (Buxaceae) in western Puerto
Rico is presented. Two populations that differ in their environmental characteristics were
studied; one is a coastal forest in the municipality ...
