We present information about the relative abundance and occurrence of the Redhead (Aythya americana), and the Ruddy Duck (Oxyura jamaicensis) in Costa Rica. The observations were conducted during the winter seasons of 2010 to 2011, 2011 to 2012, and 2012 to 2013 at different wetlands across the country. These sightings represent the southernmost records for each species. What caused these birds to such southern latitudes is unknown, because the regular wintering areas of those species occur in northern Central America or Mexico.

Geological Formation

A new genus, Tikuna, is described based on recent collections of adults and nymphs of Choroterpes atramentum Traver from western Costa Rica. All recent collections are from streams on or near the Nicoya Complex, the oldest geological formation in Lower Central America. Tikuna belongs to a lineage of South American Atalophlebiinae (Leptophlebiidae: Ephemeroptera) whose origin is hypothesized to have been in the late Cretaceous–early Tertiary. Some implications of the distribution of Tikuna for theories on the origin of Costa Rica’s biota are discussed.

Abstract C. grandis is an element of lowland and riparian, semideciduous forests, occurring naturally from Mexico to South America. The species is usually 10-15 m high, and is very ornamental, especially due to its pink flowers which appear when the tree is partially defoliate and cover the entire crown. It is used in landscape design and urban arborization in tropical America, although in some cases its use is restricted due to the size of its fruits, which can reach 40-60 cm long. The species is recommended for live fences and revegetation in gallery forests in periodically flooded areas, but it is also adapted to a more or less pronounced dry season. C. grandis can be planted under direct sunlight in mixed tree systems, in fertile soils. The species has agroforestry potential for dry zones, especially in Central America, and is recommended for arborization of perennial crops and pastures, the fruits are highly appreciated by the cattle. C. grandis requires periodical pruning, however this may cause early decay and rot. The wood is used in construction, especially for carpentry, joinery, flooring, posts, beams, also for rustic furniture, tool handles, small bridges and boats. It is considered good for charcoal and fuelwood, and inadequate for cellulose and paper. In Central America, especially in Costa Rica, the membrane which surrounds the seeds is used as a substitute for chocolate, and is also used in many countries due to its medicinal properties. Researches have shown that extracts from this plant exhibit activity against the most common dermatophytes.

Abstract. Identification of spatial variation of lithology, as a function of position and scale, is very critical job for lithology modelling in industry. Wavelet Transform (WT) is an efficacious and powerful mathematical tool for time (position) and frequency (scale) localization. It has numerous advantages over Fourier Transform (FT) to obtain frequency and time information of a signal. Initially Continuous Wavelet Transform (CWT) is applied on gamma ray logs of two different Well sites (Well-1039 & Well-1043) of Costa Rica Convergent Margin, Central America for identifications of lithofacies distribution and fracture zone later Discrete Wavelet Transform (DWT) applied to DPHI log signals to show its efficiency in discriminating small changes along the rock matrix irrespective of the instantaneous magnitude to represent the fracture contribution from the total porosity recorded. Further the data of the appropriate depths partitioned using above mathematical tools are utilized separately for WBFA. As consequences of CWT operation it is found that there are four major sedimentary layers terminated with a concordant igneous intrusion passing through both the wells. In addition of WBFA analysis, it is clearly understanding that the fractal dimension value is persistent in first sedimentary layers and the last gabbroic sill intrusions. Inconsistent value of fractal dimension is attributed to fracture dominant in intermediate sedimentary layers it is also validate through core analysis. Fractal Dimension values suggest that the sedimentary environments persisting in that well locations bears abundant shale content and of low energy environments.

Seasonal influenza affects a considerable proportion of the global population each year. We assessed the association between subnational influenza activity and temperature, specific humidity and rainfall in three Central America countries, <em>i.e.</em> Costa Rica, Honduras and Nicaragua. Using virologic data from each country’s national influenza centre, rainfall from the Tropical Rainfall Measuring Mission and air temperature and specific humidity data from the Global Land Data Assimilation System, we applied logistic regression methods for each of the five sub-national locations studied. Influenza activity was represented by the weekly proportion of respiratory specimens that tested positive for influenza. The models were adjusted for the potentially confounding co-circulating respiratory viruses, seasonality and previous weeks’ influenza activity. We found that influenza activity was proportionally associated (P&lt;0.05) with specific humidity in all locations [odds ratio (OR) 1.21-1.56 per g/kg], while associations with temperature (OR 0.69-0.81 per °C) and rainfall (OR 1.01-1.06 per mm/day) were location-dependent. Among the meteorological parameters, specific humidity had the highest contribution (~3-15%) to the model in all but one location. As model validation, we estimated influenza activity for periods, in which the data was not used in training the models. The correlation coefficients between the estimates and the observed were ≤0.1 in 2 locations and between 0.6-0.86 in three others. In conclusion, our study revealed a proportional association between influenza activity and specific humidity in selected areas from the three Central America countries.
