Comparación de la habilidad reproductiva y mortalidad del ácaro Varroa destructor en celdas con cría de obrera y zángano en abejas africanizadas de Costa Rica
(Universidad Nacional, Costa Rica, 2014-10-31)
Se estudió la reproducción del ácaro Varroa destructor en celdas con cría de obrera
y zángano. Además se evaluó la mortalidad de la progenie de V. destructor, especialmente la
muerte o ausencia del macho. El estudio se ...
An unusual recruitment strategy in a mass-recruiting stingless bee, Partamona orizabaensis
(Springer-Verlag Berlin Heidelberg, 2016-07-13)
Foragers of several stingless bee species deposit attractive scent marks on solid substrates to precisely recruit nestmates to food. Interestingly, Partamona workers quickly recruit large numbers of nest mates to resources, ...
A New Sulfur and Carbon Degassing Inventory for the Southern Central American Volcanic Arc: The Importance of Accurate Time-Series Data Sets and Possible Tectonic Processes Responsible for Temporal Variations in Arc-Scale Volatile Emissions
(AGU Publications, 2017-12-12)
This work presents a new database of SO2 and CO2 fluxes from the Southern Central American Volcanic Arc (SCAVA) for the period 2015–2016. We report 300 SO2 flux measurements from 10 volcanoes and gas ratios from 11 volcanoes ...
Seismogenic zone structure beneath the Nicoya Peninsula, Costa Rica, from three-dimensional local earthquake P- and S-wave tomography
(Geophysical Journal International, 2006)
The subduction plate interface along the Nicoya Peninsula, Costa Rica, generates damaging large (Mw > 7.5) earthquakes. We present hypocenters and 3-D seismic velocity models (VP and VP/VS) calculated using simultaneous ...
A Creep Event on the Shallow Interface of the Nicoya Peninsula, Costa Rica Seismogenic Zone
(American Geophysical Union, 2004)
Summary of the paper "A Creep Event on the Shallow Interface of the Nicoya Peninsula, Costa Rica Seismogenic Zone"
Crustal structure along the southern Central American volcanic front
(American Geophysical Union, 2008-08-20)
Subduction alters continents several ways, including accretion, magmatic addition, mantle wedge serpentinization, and crustal differentiation. These changes affect seismic velocities, so characterizing upper plate crust ...
Active Thrusting in the Inner Fore arc of Middle America, Costa Rica
(American Geophysical Union, 2004)
Summary of the paper "Active Thrusting in the Inner Fore arc of Middle America, Costa Rica"
Tomographic evidence for a subducted seamount beneath the Gulf of Nicoya, Costa Rica: The cause of the 1990 Mw = 7.0 Gulf of Nicoya earthquake
(American Geophysical Union, 2002-04-26)
Tomographic images constrain the existence of a subducted seamount beneath the Gulf of Nicoya, Costa Rica. The subducted seamount is found at a depth of 30 km within the rupture area of the March 25, 1990, Mw = 7.0 Gulf ...
An improved P-wave velocity reference model for Costa Rica
(Universidad Nacional Autónoma de México, 2001-01-01)
Derivamos un modelo de velocidad unidimensional para la onda P en Costa Rica, el cual puede servir en la rutina de localización de eventos sísmicos y como modelo de referencia para tomografía en 3 dimensiones. La inversión ...
