Evaluación de la calidad del agua en el embalse hidroeléctrico El Quimbo

Entre Ciencia e Ingeniería, 2020
 Los embalses construidos para las hidroeléctricas además de proveer energía, también son reservorios de agua para consumo humano, animal y riego en cultivos agrícolas, por tal motivo es importante evaluar la calidad de estas aguas periódicamente.

Microtopography and land management drive the spatial and population structures of a Mediterranean keystone species

Ecosphere, Volume 17, Issue 1, January 2026.
Abstract Environmental and human factors shape the distribution and habitat of Mediterranean woody plants, influencing their population structure and conservation. The Iberian wild pear (Pyrus bourgaeana), a keystone fleshy‐fruited species supporting wildlife during resource‐scarce periods, is one such example.

Interannual variability in glacier contribution to runoff from a high‐elevation Andean catchment: understanding the role of debris cover in glacier hydrology

Hydrological Processes, Volume 33, Issue 2, Page 214-229, 15 January 2019., 2019
Abstract We present a field‐data rich modelling analysis to reconstruct the climatic forcing, glacier response, and runoff generation from a high‐elevation catchment in central Chile over the period 2000–2015 to provide insights into the differing contributions of debris‐covered and debris‐free glaciers under current and future changing climatic ...

Genomic Connectivity and Adaptation Signals of the Freshwater Sponge Ephydatia muelleri Across Its Distribution

Journal of Biogeography, Volume 53, Issue 1, January 2026.
ABSTRACT Aim Genetic connectivity and local adaptation were examined across the distribution of the freshwater sponge Ephydatia muelleri. Because it occupies an exceptional breadth of freshwater environments across a broad geographic range, this species offers key insights into biogeographic processes shaping genetic structure and adaptation in inland ...

A New Fuel Design for Two Different HW Type Reactors

Science and Technology of Nuclear Installations, Volume 2011, Issue 1, 2011., 2011
A new fuel element (called CARA) designed for two different heavy water reactors (HWRs) is presented. CARA could match fuel requirements of both (one CANDU and one unique Siemens′s design) Argentine HW reactors. It keeps the heavier fuel mass density and hydraulic flow restriction in both reactors together with improving both thermomechanic and ...

Modeling nature‐based restoration potential across aquatic–terrestrial boundaries

Conservation Biology, Volume 39, Issue 5, October 2025.
Abstract Today, few watersheds remain untouched by global change processes arising from climate warming, impoundments, channelization, water extraction, pollution, and urbanization. The need for restoration has resulted in a myriad of interventions, generally performed at small scales, which have limited measurable impact in restoring biodiversity and
