Sin embargo, los registros existentes no son suficientes para determinar el estado de sus comunidades, lo que hace cada vez más difícil continuar con la labor de conservación y protección de estos organismos. Este trabajo buscó identificar de manera preliminar algunas de las familias y especies de herpetofauna asociadas a esta reserva natural tomando como referencia las unidades paisajísticas del bosque de galería y la subcuenca del río Camoa, las cuales han estado bajo presión de actividades antrópicas. Allí, se realizaron recorridos longitudinales y capturas directas en dos puntos de muestreo durante jornadas diurnas y nocturnas. Se registraron nueve especies de las familias Ranidae, Hylidae, Bufonidae, Testudinidae, Dipsadidae, Colubridae, Teiidae, Sphaerodactylidae y Gekkonidae. Además, se reporta por primera vez la presencia de geckos invasores del género Hemidactylus, por lo que se debe continuar con monitoreos sobre el estado actual de esta posible población invasora y su impacto sobre las poblaciones nativas, así como generar reportes sobre el estado de la comunidad de herpetofauna en esta zona, especialmente durante diferentes épocas del año.","PeriodicalId":193519,"journal":{"name":"Revista Mutis","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128857454","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Debido a que la principal contaminación de las cuencas está dada por descargas de aguas residuales, se han implementado las ptar para su mitigación. En esta investigación se presenta, el diagnóstico del estado actual de las (PTAR), análisis de los factores climatológicos y meteorológicos, además de las posibles afectaciones a nivel salud, aplicando la metodología del IPCC de 2006. En el caso de la cuenca del río Bogotá, la mayor generación de gei corresponde a CH4 (82,163 %) y N2O (76,059 %), siendo la cuenca media la que reporta mayores impactos, así: tratamiento mixto (45,1 %) con mayor influencia del cambio climático, actividades económicas industriales con alto impacto (70,17 %), factores climáticos como bajas temperaturas y precipitación media. De las cuencas del Valle de México, la cuenca baja reporta mayor impacto, así: tratamiento aerobio (62,11 %), actividades económicas comerciales (56,10 %), factores climáticos con una preferencia de temperatura y precipitaciones altas. De la cuenca del río Rímac, en Perú, la cuenca media reporta mayor impacto, así: tratamiento mixto (49,4 %), actividades económicas comerciales (59,2 %) y factores climáticos como precipitaciones y temperaturas altas. La validación de los datos anteriores fue confirmada con el inventario nacional de gei reportado por cada país, evidenciando que el tratamiento, el tipo de actividad económica y el clima son factores que influyen en la generación de gei.

Rice husk, an abundantly agricultural waste in Colombia, could be a low cost adsorbent for molecules such as dyes or heavy metals in effluent streams. In this research, we address the production and characterization of rice husk ash obtained by chemical activation with phosphoric acid as an adsorbent material. The physical-chemical properties of the materials were evaluated using different characterization techniques, such as close analysis, iodine number, adsorption of methylene blue, adsorption-desorption of nitrogen, analysis of the functional groups on the surface of the adsorbent through infrared spectroscopy (ftir), as well as an analysis of the morphology with scanning electron microscopy (sem). The materials have a surface area around 320 m2 /g, which decreases depending on the amount of acid used in the activation. The pore size in the studied samples ranged between 4 and 12 nm, which suggest that mesoporous solids were obtained. Regarding the adsorption of methylene blue, results show that the production of the activated ashes from rice husk as adsorbent materials is viable, presenting a new opportunity for the use of materials considered as agricultural waste.","PeriodicalId":193519,"journal":{"name":"Revista Mutis","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131097339","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study evaluated the efficiency of a vertical tree nursery model with A. cervicornis fragments in San Martin de Pajarales Island (Oceanario, Center for Research, Education and Recreation [Ceiner], Corales del Rosario and San Bernardo National Park [Pnncr y Sb , in Spanish], Colombia), where 10 vertical nurseries were installed (5 morfotypes). A total of 12 fragments from each morfotype were studied, determining their growth (linear and ecological volume), survival and health status. Morfotypes evaluated behaved similarly in both growths. Likewise, the survival of fragments by morfotype was high, varying from 90 to 100%, with algal overgrowth being the most recurrent sign causing partial mortality. This demonstrates the lowcost efficiency of floating nurseries as a meth-od for the restoration of this type of ecosystem.","PeriodicalId":193519,"journal":{"name":"Revista Mutis","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122722943","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to increase the accumulation of carotenoids in the microalga Scenedesmus dimorphus, salinity (NaCl and KNO3) and blue LED light were evaluated as stress factors when reaching the stationary phase of culture growth in such microalga. After evaluation, the bestof the two salts studied was KNO3 0.6M, since this culture reached the highest concentration of total carotenoids (0.3357±0.02 μg carotenoids mL-1), in contrast to 0.1791±0.01 µg mL-1 with NaCl 0.6 M. Subsequently, the process was scaled in an adapted container of 4 L, entering the stationary phase on day 12. On day 14 the KNO3 was added at 0.6 M; this experiment lasted 20 days of cell count, obtaining on the last day a total of 0, 7395±0, 05 μg of carotenoids mL-1 by means of spectrophotometry. Afterwards, drying of the culture with salinity was carried out, obtaining a dry weight of 5.7 g, with a productivity of 0.0927 g L-1d-1. Final- ly, through HPLC CHRomatography, the lipid profile of the culture was analyzed, resulting in 21.1% MUFAS, 35.9% sFAS, and 43% PUFAS (34% omega-6 and 8.9% omega-3). Based on the above, it was determined that salinity is a possible factor to increase in a greater proportion the concentration of lipids than that of ca- rotenoids, specifically in a ratio of 1:2,500 carotenoids and lipids, respectively.","PeriodicalId":193519,"journal":{"name":"Revista Mutis","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130569648","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
