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 ...
Lluvia de semillas bajo árboles nativos e introducidos en el Refugio Nacional de Vida Silvestre de Cabo Rojo, Puerto Rico
(2006)
Seed rain is mechanism used by plants to colonize new sites, escape from predators or inhibitors present under the mature tree and reach safe micro sites to germinate. Most of the ecological studies on seed rain have been ...
Distribution, habitat occupancy and population density of the Elfin-woods Warbler (Dendroica angelae) in Puerto Rico
(2006)
The Elfin-woods Warbler (Dendroica angelae) is a threatened species endemic to
montane forests in Puerto Rico. The objectives of this study were to determine the current
geographical distribution, spatial distribution ...
Degradación de biodiesel y diversidad bacteriana en suelos arenosos de una zona industrial (Guayanilla, Puerto Rico)
(2005)
Biodegradation of biodiesel from an industrial impacted sandy soil (Guayanilla Bay,
Puerto Rico) and bacterial diversity was evaluated. Soil samples were amended with
2,500 mg/Kg of biodiesel and incubated during 41 days ...
Disponibilidad de presas para aves playeras en las salinas de Cabo Rojo, Puerto Rico y su relación con los factores físicos de la región
(2006)
The Cabo Rojo, Puerto Rico salterns constitute one of the most impressive ecological realms of the island. Besides harboring a rich invertebrate fauna, thousands of birds have made a feeding and rest stopover of the area ...
Fungal diversity present at a hypersaline environment in Cabo Rojo, Puerto Rico, determined by characterization of isolates and analysis of environmental rRNA genes clones libraries
(2006)
Solar salterns are a thalassohaline environment where sea water is evaporated to obtain salt for commercial purposes. The prokaryotic diversity on these places has been extensively studied world wide. However, there are ...
Fluorescence-based assessment of total protease activity/trypsin as a function of variable soybean content in fines fed to the gray tilapia (Oreochromis niloticus) and the red tilapia (Oreochromis hornorum)
(2007)
This study evaluated the effect of five diets, differing from one another based upon ratio of
raw soybean/processed soybean content, upon both biomass production and intestinal
protease activity in gray tilapia (Oreochromis ...
Variación en la dieta del sapo de la caña (Chaunus [Bufo] marinus) en la reserva natural privada el tallonal en Arecibo, Puerto Rico
(2008)
The cane toad, Chaunus [Bufo] marinus, introduced in Puerto Rico, is known for
having a varied diet and for being an opportunist species, thus its diet reflects regional and
seasonal abundance of prey. In order to know ...
Detection and identification of Cryptococcus neoformans/gattii complex in novel environmental samples using physiological and genetic tools
(2008)
Cryptococcus neoformans/gattii complex (C.neo/gat) are opportunistic, encapsulated yeasts that adversely affect primarily immune-suppressed patients. The yeasts live freely in the environment, mainly associated to pigeon ...
Possible role of adenine and thymine rich sequence in the encapsidation pattern of Parvovirus LuIII
(2007)
LuIII is a small, non-enveloped, icosahedral autonomous parvovirus that contains a small
linear (5 kb) single stranded DNA genome and infects human cell lines lytically with no
evidence of integration into cellular DNA. ...
