Recent taxonomic works have recognized only two species of spiny pocket mice of the genus Heteromys (Rodentia: Heteromyidae) from Costa Rica. Within Costa Rica, the widespread H. desmarestianus is considered to occur throughout the wet Caribbean lowlands, as well as at middle and high elevations on the Caribbean and Pacific slopes of the country’s main montane systems. In contrast, H. oresterus...

This article describes the progress-as well as the challenges and limitations-in reducing salt intake in Costa Rica. The National Plan to Reduce Public Consumption of Salt/Sodium in Costa Rica 2011 - 2021 was complemented with multisectoral programs and projects specifically designed to: 1) determine sodium intake and the salt/sodium content of the most widely consumed foods; identify the consu...

This case study was conducted to determine the benefits of a multi-dimensional study abroad program that included a community service component. It encompassed the following aspects of the study abroad experience: motivation for travel, language learning research, the role of autonomy in language learning, and cultural awareness, behaviors, and attitudes. The researcher acted as a participant a...

[1] Although most Central American magmas have a typical arc geochemical signature, magmas in southern Central America (central Costa Rica and Panama) have isotopic and trace element compositions with an ocean island basalt (OIB) affinity, similar to the Galapagos-OIB lavas (e.g., Ba/La < 40, La/Yb > 10, Pb/Pb > 18.8). Our new data for Costa Rica suggest that this signature, unusual for a conve...

This is the first report of the sipunculan Aspidosiphon (Aspidosiphon) elegans (Chamisso & Eysenhardt, 1821) in the tropical eastern Pacific. With this species the number of coral borers rises to 18 for this region. The upogebiidid crustacean Pomatogebia rugosa (Lockington, 1878) was reported previously (as Upogebia rugosa) from coral colonies in the Gulf of California, Mexico, and from coral r...

After finding distinct clades in a molecular phylogeny for Nepticulidae that could not be placed in any known genera and discovering clear apomorphic characters that define these clades, as well as a number of Neotropical species that could be placed in known genera but were undescribed, three new genera and nine new species are here described from the Neotropics: Stigmella gallicola van Nieuke...

Socioeconomic Development, Health Interventions and Mortality Decline in Costa Rica. Rosero-Bixby, L. (Department of Population Planning, University of Michigan, Ann Arbor, USA). Scand J Soc Med 1990, suppl 46: 33-42. Costa Rica, whose life expectancy was 74 years by 1985, has reached a health level comparable to a developed country. The health achievements of this country are product of politi...

Rhinella marina is a toad native to South America that has been introduced in the Antilles, likely carrying high loads of microorganisms, potentially impacting local community diversity. The amphibian skin is involved in pathogen defense and its microbiota has been relatively well studied, however, research focusing on the cane toad microbiota is lacking. We hypothesize that the skin microbial ...
