Feeding trials of Pangasius hypophthalmus larvae, during the first 2 weeks post hatching
(2012)
A high mortality in the first two weeks after hatching makes Pangasius hypophthalmus culture challenging. Some scientists have attributed this mortality event to cannibalism and bacterial infection. Larvae were presented ...
Estatus de los nuevos ensamblajes bénticos y dinámica de lo juveniles de coral que crecen sobre colonias de Orbicella faveolata que murieron después de la anomalía térmica de 2005
(2020-05-23)
La combinación de enfermedades y el blanqueamiento intensivo durante la anomalía térmica en el año 2005 causaron la pérdida del 53% de la cobertura viva de coral en la Reserva Natural La Parguera (RNLP). Al desaparecer el ...
Spatial and temporal variations in the relative abundances of coral reef algae in Southwest Puerto Rico
(2012)
A detailed 5 year study of algal community structure at 8 coral reefs distributed across
the insular shelf at La Parguera, Puerto Rico was undertaken between 2003 and 2007. Significant
temporal variation in species cover ...
Population dynamics of hurricane-generated fragments of elkhorn coral Acropora palmata (Lamarck, 1816)
(2005-05)
Fragmentation and local dispersion of hurricane-generated fragments have been
considered an important feature in the life history, population dynamics and genetic
structure of the elkhorn coral Acropora palmata. The ...
Slow recovery of reef fish populations in an isolated marine reserve
(2018-12-12)
Geographic isolation is an important yet underappreciated factor affecting marine reserve performance. Isolation, in combination with other factors, may preclude recruit subsidies, thus slowing recovery when base populations ...
Influence of Saharan aerosols on phytoplankton biomass in the tropical North Atlantic Ocean
(2010-12)
Atmospheric transport of aerosols from desert regions of Africa supply nutrients, such as iron, to oligotrophic oceanic waters. Phytoplanktonic organisms in surface waters use bio-available Fe, increasing their rate of ...
Use of passive acoustic recordings to quantify abundance relationship from courtship associated sounds of the Nassau grouper (Epinephelus striatus) at spawning aggregation sites in Puerto Rico and the US Virgin Islands
(2015)
The Nassau grouper, Epinephelus striatus, has been overfished to commercial extinction, such that many aggregations have diminished or disappeared throughout the Caribbean. Groupers produce sound, and the objective of this ...
Genetic diversity and population structure of Caribbean marine invertebrates
(2009-12)
Natural populations of many marine invertebrates are under pressure by fisheries due
to the increasing demand and unit prices leading to overexploitation. I examined the genetic
variation of two marine invertebrates: the ...
Evaluation of ground water from the Lajas valley for low salinity culture of the Pacific white shrimp Litopenaeus vannamei
(2008-05)
The ability of the Pacific white shrimp (Litopenaeus vannamei) to acclimate to and
survive in low salinity ground water from southwestern Puerto Rico was evaluated using post
larval shrimp and well water from the Lajas ...
Characterizing zooplankton and micronekton diel vertical migration at the western Puerto Rican shelf/slope break
(2006)
Discrete zooplankton/micronekton samples from three plankton cruises were collected over a moored Bluewater Broadband ADCP in Mona Passage, west of Puerto Rico to: describe the taxonomic composition, vertical distribution, ...
