In Costa Rica there is little information about asthma admissions. In this report the monthly asthma admissions and weather data for a seven year period were reviewed. The hospital asthma admissions showed notable seasonal variation associated with variations in the rainfall and the relative humidity.

A cross-cultural analysis of mortality patterns is of interest to biological anthropologists and genetic epidemiologists. In this paper, we examine four agricultural populations from Costa Rica, Hungary, and the United States in order to determine if they suffered from a cyclical distribution of epidemics. When possible, we look at the mortality time series of adults and children separately. Of...

Anthropologists have long been interested in the survival of Indian cultural traits in the New World. In this article, we present results of an ongoing project with a Costa Rican community that descends from East Indian indentured servants. We focus on the group’s marriage patterns and how these patterns might have helped keep the community as a cohesive ethnic group. We investigate the group’s...

New distribution records of 22 braconid species belonging to Agathidinae, Braconinae, Helconinae, Homolobinae and Rogadinae subfamilies from Brazil, Chile, Costa Rica, Guatemala, Mexico and Panama are presented. Agathirsia ninesevenci Pucci & Sharkey is reported for the first time from Mexico; Homolobus acares van Achterberg, H. antefurcalis van Achterberg and H.infumator (Lyle) from Costa Rica...

Rate remapping is a conjunctive code that potentially enables hippocampal place cells to jointly represent spatial and nonspatial information. In this issue of Neuron, Rennó-Costa et al. introduce a theoretical model wherein the convergence of the medial and lateral entorhinal excitatory inputs, combined with local inhibition, explains hippocampal rate remapping.

Previously Neoidiotypa was a monotypic genus represented by a peculiar wasp-like richardiid from Cuba - N. appendiculata (Loew). In this work, five new species are described in this genus: N. mexicana sp. nov. from Mexico; N. alamagna sp. nov., N. flaviatra sp. nov., N. nigra sp. nov. and N. sticta sp. nov. from Costa Rica. New diagnostic characters for the genus are included. An identification...
