Introducción. El fenómeno del Niño de 2014-2015 evidenciado en los niveles nacional y regional tuvo impactos en ecosistemas hídricos y en las coberturas vegetales asociadas al mismo. Objetivo. Con el objetivo de establecer la relación entre la variación de la vegetación riparia y la variabilidad climática en el humedal urbano Torca-Guaymaral, se realizó la caracterización florística de la vegetación riparia asociada a este ecosistema estratégico para el borde norte de la ciudad de Bogotá. Posteriormente se plantea una propuesta metodológica de restauración enfocada a restablecer la estructura y función de la vegetación riparia, a través de la sucesión asistida. Materiales y métodos. Durante 2014-2015 se realizaron muestreos en dos épocas climáticas (húmeda y seca) en 21 unidades de muestreo para evaluar las coberturas vegetales con mayor desarrollo estructural, composición y riqueza. Los resultados reportan que existe una alta presencia de especies invasoras (Ulex europaeus y Genista monspessulana), lo cual ha generado una eliminación total de las especies nativas, una disminución en la diversidad del humedal, lo que imposibilita la llegada de nuevas especies. Resultados. Adicionalmente se encontró una relación positiva entre el incremento en la temperatura y la colonización. Asimismo, se reporta una alta dominancia en área y abundancia de las especies invasoras, lo que impide la recuperación del área con especies nativas y reduce los servicios ecosistémicos del humedal. Conclusión. Reconociendo los conflictos en el área, en este estudio se plantea una metodología para la recuperación de la vegetación riparia del sector occidental del humedal Torca-Guaymaral, en donde se involucra la sucesión vegetal asistida, el manejo de las especies invasoras y la siembra de nuevas especies.

Gorse (Ulex europaeus) and French broom (Genista monspessulana) are two highly invasive species that have become a threat to tropical countries, especially in Andean ecosystems. This research focused on providing a physicochemical characterization and essential oils extraction of both species to better understand their potential valorization and guide further environmental management efforts. For this purpose, the following analyses were conducted for both species: higher heat value (HHV), elemental analysis, proximate analysis, thermogravimetric analysis to obtain constituent natural polymers (hemicellulose, cellulose, and lignin), and extraction of essential oils and other interest chemical compounds through supercritical fluids. Ecological closeness was found between the two species mostly regarding HHV, fixed carbon, and volatile matter, which calls for similar potential uses. Both species were also found to be suitable for combustion processes, gasification, extraction of chemical compounds, and use of lignocellulosic content; however, only U. europaeus appeared suitable for activated carbon obtention. Therefore, this work provided relevant data that can be used as preliminary basis to establish strong scientifically-based management and control strategies for these two invasive species. We recommend focusing primarily on thermal processes such as pyrolysis, gasification, or combustion, and also essential oils extractions of acetic acid, dodecanoic acid, anagyrine, amylene hydrate, caulophylline, and maltol in the future.

A novel approach for preparing carbohydrate chips based on polydopamine (PDA) surface to study carbohydrate–lectin interactions by quartz crystal microbalance (QCM) biosensor instrument has been developed. The amino-carbohydrates were immobilized on PDA-coated quartz crystals via Schiff base reaction and/or Michael addition reaction. The resulting carbohydrate-chips were applied to QCM biosensor instrument with flow-through system for real-time detection of lectin–carbohydrate interactions. A series of plant lectins, including wheat germ agglutinin (WGA), concanavalin A (Con A), Ulex europaeus agglutinin I (UEA-I), soybean agglutinin (SBA), and peanut agglutinin (PNA), were evaluated for the binding to different kinds of carbohydrate chips. Clearly, the results show that the predicted lectin selectively binds to the carbohydrates, which demonstrates the applicability of the approach. Furthermore, the kinetics of the interactions between Con A and mannose, WGA and N-Acetylglucosamine were studied, respectively. This study provides an efficient approach to preparing carbohydrate chips based on PDA for the lectin–carbohydrate interactions study.

This study analyzes the natural and social factors influencing the emergence and publicization of the invasive status of a fast growing bush, gorse (Ulex europaeus), by comparison between countries on a global scale. We used documents collected on the web in a standardized way. The results show that in all the countries studied, there are several public statuses attributed to gorse. The invasive status is the one that is most shared. The other most frequently encountered status are those of noxious weed, and of economically useful. The invasive status is publicized in nearly all countries, including those where gorse is almost absent. We quantified the publicization of the invasive gorse status of gorse by an indicator with 5 levels, and then performed a multivariate analysis that combines natural and social explanatory variables. The results lead us to propose the concept of invasive niche: the set of natural and social parameters that allow a species to be considered invasive in a given socio-ecosystem.
