Ictiofauna y desarrollo del sector hidroeléctrico en la cuenca del río Magdalena-Cauca, Colombia
The Magdalena-Cauca River basin has 213 species of freshwater fish, of which slightly more than 50% are
endemic. This basin accounts for 80% of the Colombian population, holds 80% of the national GDP and within its
channels are located the 84% of the hydroelectric plants that supply energy to Colombia. The Andean mountains
generate altitudinal gradients in aquatic systems as well as its associated biota along the Magdalena-Cauca basin.
To analyze the interaction between the altitudinal gradient in the distribution of species of freshwater fish and
the location of existing reservoirs, it was performed an analysis of the altitudinal distribution of endemic and
migratory fish species and their implications for their conservation based on the current and future state in the
formation of reservoirs, using a review of case studies at global and national levels. It was found that the number
of species is inversely proportional to altitude, while the endemics are directly proportional and reservoirs below
700 m altitude affect the conservation status of migratory species. A reservoir creates new species richness
gradients and modifies the channels that are used by migratory species as spawning areas. We conclude that the development of the hydropower based on the use of water in the Andean rivers and another activities associated with economic development of Colombian society, has led to changes in freshwater aquatic systems in the Magdalena-Cauca basin, influences in the structure of the assemblages of species of fish and in the dynamic of migration and spawning of freshwater fish species important for artisanal fisheries.

Identificación de los servicios ecosistémicos que proveen las diferentes áreas protegidas en la Orinoquia colombiana
This study was conducted with the support of the Young Researchers and Innovators Program 2012-
2013 of Colciencias. The aim of the study was to develop a qualitative analysis of the ecosystem services
provided by the land covers within the different categories of protected areas in the Orinoco basin. To
achieve this goal, a matrix was constructed according to the capacities of the different land covers to
provide ecosystem services and their respective conservation categories were analyzed. A survey of
experts working on protected areas was also performed. As results was obtained for each protected area management category the number of hectares and the type of land cover and ecosystem were identified. Of the total number of surveys sent to experts, 19 were completed and additional information on 3 private reserves was obtained from interviews with the owners. As conclusions, the region has a variety of land covers with different
capacities to provide regulation, provision and cultural ecosystem services. However, a complete analysis would require field work in each area in order to verify the matrix of provision capacities of ecosystem services. The information hereby presented may contribute to the effective management of the protected areas.

Carábidos (Coleoptera: Carabidae) del Museo de Entomología de la Universidad del Valle (Cali, Colombia)
Los escarabajos carábidos (Coleoptera: Carabidae) constituyen una importante porción de la diversidad de la fauna
edáfica. Dada su importancia en aspectos como el control natural de plagas y su respuesta como bioindicadores,
es importante reconocer los géneros y especies presentes en una determinada localidad, sin embargo, en Colombia
su estudio ha sido relativamente pobre. En el presente conjunto de datos se listan los géneros y algunas especies
de carábidos, depositados en el Museo de Entomología de la Universidad del Valle. Esta colección cuenta con
355 registros de 38 géneros, de los cuales sólo 10 tienen especímenes identificados a la categoría de especie.
