Abstract Páramo soils store high amounts of organic carbon. However, the effects climate change and changes in land cover use (LC/LU) this high‐elevation tropical ecosystem may cause a decrease their carbon storage capacity. Therefore, better understanding factors influencing soils' export is urgently needed. To fill knowledge gap, we investigated differences dissolved (DOC) content soil water four LC/LU types (tussock grass, natural forest, pine plantations, pasture) controlling its...
Abstract Tracer‐aided rainfall‐runoff modelling is a promising tool for understanding catchment hydrology, particularly when tracers provide information about coupled hydrological‐biogeochemical processes. Such models allow predicting the quality and quantity of water under changing climatic anthropogenic conditions. Here, we present Spatially‐distributed Tracer‐Aided Rainfall‐Runoff model with biogeochemical reactive tracer module (STARR‐DOC) to simulate dissolved organic carbon (DOC)...
ABSTRACT Population growth and poor agricultural practices demand an improvement in the efficiency of food production. Urban hydroponic crops represent a potential solution to this challenge. However, use drinking water for urban agriculture is not priority. Consequently, rainwater harvesting can reduce other purposes than human consumption. This study evaluated production Andean city. We developed model analyze optimization two scenarios: (1) domestic (30 plants) (2) small-scale commercial...
Abstract Monitoring the temporal variation of solute concentrations in streams at high frequency can play an important role understanding hydrological and biogeochemical behaviour catchments. UV–visible spectrometry is a relatively inexpensive easily used tool to infer those resolution. However, it not yet clear which solutes be modelled with such in‐situ sensor. Here, we installed spectrometer probe (200–750 nm) high‐altitude tropical Páramo stream record wavelength absorbance 5‐min For...

En la industria avícola, existen diferentes tipos de Escherichia coli patógenos y no patógenos, según los genes asociados a virulencia (VAG) presentes en bacteria. Sin embargo, reportes sobre identificación VAG E. pollos engorde son limitados, especialmente comunidades andinas ecuatorianas. El objetivo principal este estudio consistió identificar diversidad genética presencia cepas coli. Se caracterizaron varias granjas provincia del Azuay (sur Ecuador) partir 30 aislados cultivos...
The Páramo is a high‐elevation tropical grassland ecosystem that plays an important role in the regional water cycle of Central America and northern Andes. However, refined information about ecohydrological partitioning these mountainous biomes scarce. This work aimed to assess sub-annual or monthly variations conditions along N-S transect with three sites: Chirripó (Costa Rica) El Carmen Cajas (north south Ecuador, respectively). A Budyko-type model for under...
Thyroid nodules are relatively prevalent in clinical practice; they found by palpation 3-7% of the general population and ultrasonography (US) roughly 50%. Image-guided nonsurgical procedures such as ethanol ablation (EA) or radiofrequency (RFA) have been proposed for a selected group patients alternatives to traditional treatments. We present case low-risk follicular variant papillary thyroid cancer treated successfully with EA after examination identification nodule an ideal candidate...
<p>In-situ monitoring of the temporal variation solutes’ (nutrients and metals) concentrations as tracers can enhance knowledge hydrological biogeochemical behavior catchments. UV-Visible spectrometry represents a relatively inexpensive easily used tool to explore how those vary in time at high frequency. However, it is not yet clear which are best calibration methods solutes be modeled with this approach. In investigation we explored relationship between...
