Desiccation Tolerance of Epiphytic Macrolichens in an Evergreen Temperate Rain Forest (Alerce Costero National Park, Chile).

The Valdivian region has a temperate rainy climate with differences in rainfall throughout the year. This heterogeneity results in periods of summer drought that expose the poikilohydric epiphytes to desiccation. With this research, we aim to answer different research questions related to phorophyte preference, response to desiccation, and response to radiation.

Astrocyte CCN1 stabilizes neural circuits in the adult brain.

Neural circuits in many brain regions are refined by experience. Sensory circuits support higher plasticity at younger ages during critical periods - times of circuit refinement and maturation - and limit plasticity in adulthood for circuit stability. The mechanisms underlying these differing plasticity levels and how they serve to maintain and stabilize the properties of sensory circuits remain largely unclear.

Influence of salt and temperature in the growth of pathogenic free-living amoebae.

Introduction: Free-living amoebae are an extensive group of protistans that can be found in a wide variety of environments. Among them, the genus and stand out as two of the most pathogenic amoebae and with a higher number of reported cases. is mainly found in warm freshwater water bodies whereas amoebae of the genus are broadly distributed through natural and anthropogenic environments.
