Recomendaciones para mejorar el manejo de comederos artificiales para colibríes
(2019)El uso de comederos artificiales para alimentar a las aves es una práctica extendida y de uso generalizado principalmente en sitios turísticos, tales como hoteles de montaña, parques naturales, y jardines privados. En el ... -
Rediscovering the value of families for psychiatric genetics research
(2018-06-28)As it is likely that both common and rare genetic variation are important for complex disease risk, studies that examine the full range of the allelic frequency distribution should be utilized to dissect the genetic ... -
Reduced activity of Arabidopsis chromosome-cohesion regulator gene CTF7/ECO1 alters cytosine methylation status and retrotransposon expression
(2015-05-01)Multicellular organisms such as higher plants require timely regulation of DNA replication and cell division to grow and develop. Recent work in Arabidopsis has shown that chromosome segregation during meiosis and mitosis ... -
Regeneración de la vegetación arbórea en una pequeña reserva forestal urbana del nivel premontano húmedo, Costa Rica
(Rev. Biol. Trop., 44(2): 575-580,1996, 1996)The tropical premontane moist forest is one of the most destructed Iife zones in Costa Rica. For such regions, a small natural preserve system has been proposed. An inventory of trees greater ... -

Relationship between isoprene emission and photosynthesis in diatoms, and its implications for global marine isoprene estimates
(2017)Global consensus estimates of marine isoprene emission (~ 1 TgC yr− 1) is significantly smaller than terrestrial isoprene emission (~ 500 TgC yr− 1), and the reasons are unclear. With the premise that isoprene emission is ... -
Relationship between species richness of excavator birds and cavity–adopters in seven tropical forests in costa rica
(2009)The abundance of wood cavities is thought to be a limiting factor for bird species that depend on these cavities for nesting. Thus, it is expected that number of cavity adopters correlates with number of cavity excavators ... -
