Metazoan parasites of Groupers (Epinephelinae, Pisces) from Puerto Rico
(2008)
The subfamily Epinephelinae (Groupers) is a major group of commercially important
fishes of the world with 19 species reported from Puerto Rico. The goal of the present study was
characterize the diversity of parasites ...
Elemental composition, web architecture, and morphometrics: The case of Leucauge venusta (Walckenaer, 1842) in three forests of Puerto Rico
(2019-12-05)
Web building spiders are usually passive predators that do not typically change their location once they are established; this suggests that factors such as vegetation and canopy density could have a significant influence ...
Current habitat selection and use of the endangered lizard Anolis cooki (Grant, 1931) in the presence of Anolis cristatellus (Duméril and Bibron, 1837), in the Cabo Rojo National Wildlife Refuge at Cabo Rojo, Puerto Rico
(2019-12-06)
The study of habitat selection and use by an Anolis species on different types of forest formations at different times of day has not been well documented. Interspecific studies have suggested that anoles use and select ...
Plant diversity and vegetation structure as factors correlated with parasitoid wasp (Hymenoptera: Braconidae and Ichneumonidae) diversity in a degraded dry forest ecosystem in Puerto Rico
(2013)
Tropical dry forests worldwide have a long history of human use, invasion by non-native species
and degradation. In Puerto Rico, while overall forest cover has increased due to socioeconomic
and land use changes over the ...
The toxicity of liquid edger herbicide on the brine shrimp Artemia franciscana
(2008)
The effect of 0.0001 and 0.00001 mg/L concentrations of Liquid Edger (LE) herbicide was
evaluated on the parental generation, F1 and F2 of Artemia franciscana. The criteria evaluated
were parental life span, survival to ...
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 ...
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 ...
Microbial diversity of a fluidized-bed bioreactor treating diesel-contaminated groundwater (Vega Baja, Puerto Rico)
(2006)
Culture and culture-independent techniques were used to characterize the microbial
community structure within a fluidized bed reactor (FBR) used to remediate a dieselcontaminated
aquifer. Under normal operating conditions, ...
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 ...
Assessing origin and genetic diversity through maternal lineages and "Gait Keeper" (DMRT3) frequency of Puerto Rican horses
(2016)
Since their domestication, horses demonstrated their usefulness for transportation, warfare, agriculture, sports and even companionship, earning a central role in human history. Over the centuries, horse breeds have been ...
