Estudios sobre la estabilidad del virus del rayado fino del maíz por degradación enzimática del ARN viral y microscopia electrónica de las partículas
(1986)
The stability of "Maize Rayado Fino Virus" capsids was studied correlating enzymatic degradation analysis of the RNA in full capsids with electron microscopy of negatively stained particles. The great thermal stability of ...

A method for genetic transformation of maize for resistance to viral diseases. A system for the genetic transformation of maize was developed for two Costa Rican varieties: CR-7 and Diamantes 8843, that can allow the ...
Photochemical efficiency of adult and young leaves in the neotropical understory shrub Psychotria limonensis (Rubiaceae) in response to changes in the light environment
(Revista de Biologia Tropical 52 (4): 839-844, 2004-12)
We explored the short-term adjustment in photochemical efficiency (Fv/Fm) in adult and young leaves of the understory neotropical shrub Psychotria limonensis Krause (Rubiaceae) in response to rapid changes in the light ...
Impact of El Niño 2015-2016 on the coral reefs of the Pacific of Costa Rica: the potential role of marine protection
Impacto del fenómeno El Niño 2015-2016 en arrecifes coralinos del Pacífico de Costa Rica
(2020)
Introduction: El Niño 2015-2016 was considered one of the most severe worldwide, causing the third global event of coral bleaching. Previous high-intensity El Niño events (1982-83 and 1997-98) caused high coral mortalities ...
