Neotropical dry forest wildlife water hole use and management
(Universidad Nacional, Costa Rica., 1999)Selected wildlife species diurnal use of a natural water hole (QO) and an artificial water hole (AW) were studied during 1990 dry season at Guanacaste Conservation Area, Costa Rica. In total, 919 individuals (six marnmal ... -
Nest-specific composition of the trail pheromone of the stingless bee Trigona corvina within populations
(Springer, 2012)Social insects have evolved highly developed communication systems, enabling them to coordinate complex interactions in their colonies. Pheromones play a major role in the coordination of many tasks. In Trigona corvina, a ... -
New Bruce-ladder multiplex PCR assay for the biovar typing of Brucella suis and the discrimination of Brucella suis and Brucella canis
(Revista de Microbiología Veterinaria, 2011-06-28)Rapid and specific identification of Brucella suis at the biovar level is necessary because some of the biovars that infect animals are pathogenic for humans. None of the molecular typing methods described so far are ... -
New insights into Kawah Ijen’s volcanic system from the wet volcano workshop experiment
(Geological Society London Special Publications, 2016-02-25)Volcanoes with crater lakes and/or extensive hydrothermal systems pose significant challenges with respect to monitoring and forecasting eruptions, but they also provide new opportunities to enhance our understanding of ... -
New Record of the Small Hive Beetle, Aethina tumida, in Africanized Honey Bee Colonies in Costa Rica
(Bee World, 2019-02-27)The small hive beetle (SHB) Aethina tumida Murray (Insecta: Coleoptera: Nitidulidae) is a honey bee parasite native to sub-Saharan Africa (Hepburn & Radloff, 1998). It was first described by Murray in 1867. In 1996, SHBs ... -
Nicoya earthquake rupture anticipated by geodetic measurement of the locked plate interface
(Nature Research, 2013-12-22)The Nicoya Peninsula in Costa Rica is one of the few places on Earth where the seismically active plate interface of a subduction zone is directly overlaid by land rather than ocean. At this plate interface, large megathrust ... -
Nitrogen recycling at the Costa Rican subduction zone: The role of incoming plate structure
(Springer Nature, 2017-10-24)Efficient recycling of subducted sedimentary nitrogen (N) back to the atmosphere through arc volcanism has been advocated for the Central America margin while at other locations mass balance considerations and N contents ... -

(Revista Ciencias Veterinarias, UNA, 2021-06-27)The presence of nosemosis in Africanized honey bees in Costa Rica was studied. A total of 75 samples of adult bees from different country regions were selected for molecular diagnosis of nosemosis. Prior to PCR tests, ... -
Nosemosis in africanized honey bee colonies in tropical conditions of Costa Rica: Nosema apis or Nosema cerenae
(Revista de Ciencias Veterinarias, UNA, 2021-06-17)The presence of nosemosis in Africanized honey bees in Costa Rica was studied. A total of 75 samples of adult bees from different country regions were selected for molecular diagnosis of nosemosis. Prior to PCR tests, ... -
Not Only Toxic but Repellent: What Can Organisms’ Responses Tell Us about Contamination and What Are the Ecological Consequences When They Flee from an Environment?
(Multidisciplinary Digital Publishing Institute (MDPI), 2020-12-12)The ability of aquatic organisms to sense the surrounding environment chemically and interpret such signals correctly is crucial for their ecological niche and survival. Although it is an oversimplification of the ... -
