Local adaptation corresponds to the processes that arise because natural selection in heterogeneous environments is opposed to the homogenizing effects of neutral processes such as gene flow. In coastal marine habitats, many animals have dispersive larval stages that allow connectivity between lo...

La adaptación local corresponde a aquellos procesos que surgen debido a que la selección natural en ambientes heterogéneos se contrapone a los efectos homogenizadores de procesos neutrales como el flujo genético. En hábitats marinos costeros, muchos animales cuentan con estadios larvales dispers...

El uso intensivo de antimicrobianos en la salmonicultura Chilena y su consecuente aumento de la resistencia bacteriana en ambientes asociados a cultivos acuícolas, representa un grave riesgo sanitario. En Chile, a pesar de su importancia en salud humana las quinolonas siguen siendo utilizadas en ...

El “Antropoceno” se caracteriza por pertubaciones de origen humano que conllevan impactos globales. Por ejemplo, los cambios de uso/cobertura del suelo (LUCC) son conocidos por perturbar el ciclo del N a partir de la Revolución Industrial pero especialmente desde la Gran Aceleración (1950 CE) en ...

Prochlorococcus and Synechococcus are the most abundant free-living photosynthetic microorganisms in the ocean and represent approximately 25% of marine primary productivity. Uncultivated lineages of these picocyanobacteria also thrive in the dimly illuminated (<1% of incident light) and high nut...

Conceptually, in evolution, the variable “time” is fundamental. Extant populations are the result of long- and short-term historical processes affecting them through time. Populations in areas near the poles have been exposed to extreme changes in landscape during the Quaternary glacial cycles. T...

The Arctic has warmed rapidly, increasing shrub cover and density, and thawing permafrost. Understanding, quantifying and predicting the impact of these environmental changes on the hydrological regime of Arctic headwater basins represents a great scientific challenge, particularly due to the spa...

The Juan Fernández Ridge (JFR) is an intraplate volcanic chain (~ 800 km) emplaced above the Nazca Plate in the SE Pacific, isolated from the nearby active spreading ridges (East Pacific Rise and Chile Ridge). Through geochemistry (in whole rock and crystals), isotopic data (Sr-Nd-Pb) and geochro...

La Dorsal de Juan Fernández (JFR) es una cadena volcánica (~ 800 km) de intraplaca emplazada sobre la Placa de Nazca en el Pacífico SE alejada de márgenes activos. Mediante datos de geoquímica (roca total y mineral), isotópicos (Sr-Nd-Pb) y geocronológicos (40Ar/39Ar) se busca comprender los proc...

Food waste is considered a social, environmental and economic problem. Concerns are based, amongst other things, on the environmental damage produced by the food supply chain (FSC) and the substantial amount of food that is wasted. This work reviews the relationship between food waste and the en...

Eastern boundary upwelling systems (EBUSs) are distinguished from other systems by the recurrent fertilizing effect of wind-induced upwelling processes, which stimulate a high productivity in coastal areas. Among the main EBUSs in the Atlantic and Pacific Oceans, some of them have been insufficie...
