Abstract

In recently deglaciated soils, microbial organisms drive soil transformations by increasing carbon (C) and nitrogen (N) pools while depleting available phosphorous (P), thus improving plant colonization and soil development. However, the rate of soil development can vary in response to local environmental conditions that affect microbial abundance and activity. In this contribution we use observational and experimental approaches to evaluate the interplay between soil biogeochemical features and microbial abundance and function after approximately seventy years of soil development in the forefield of the Exploradores Glacier that is located at the northernmost end of the Northern Patagonian Ice Field.

Abstract

To legally permit greywater reuse as a management strategy, it is necessary to establish allowed uses, as well as guarantee legitimacy, safety and maintain public trust. Cities with previous experience in greywater reuse have reconfigured their regulations according to their own evidence with decentralized water reuse systems. This has allowed them to encourage or restrict certain indoor uses of treated greywater. However, cities starting to use these residential schemes lack the experience to reconfigure their water and sanitation regulation, and thus need “blindly” decide on the type of greywater uses to allow in order to achieve a balance between users’ acceptability and avoiding public health problems.

Abstract

Climate change is modifying the way we design and operate water infrastructure, including reservoirs. A particular issue is that current infrastructure and reservoir management rules will likely operate under changing conditions different to those used in their design. Thus, there is a big need to identify the obsolescence of current operation rules under climate change, without compromising the proper treatment of uncertainty.

Abstract

The effect of shelter tubes on plant performance has been widely studied. Although, the role of shelter tubes in alleviating the effects of drought and high-irradiance stresses during seedling establishment has been less studied than its effect on survival. The present study compares the effects of shelter tubes with different light transmissivities (Lt) on survival and morpho-physiological responses of two coexisting tree species (drought-tolerant Quillaja saponaria and relatively more drought-sensitive Maytenus boaria) of the Chilean matorral during an exceptionally dry and warm growing season (2014–2015).

Abstract

Land-use and land-cover (LULC) changes are major drivers of biodiversity loss in semi-arid regions, such as the Caatinga biome located in the Northeast of Brazil. We investigated landscape dynamics and fragmentation in an area of the São Francisco Valley in the Brazilian Caatinga biome and measured the effect of these dynamics on ecological, functional and structural connectivity over a 33-year period (1985–2018). We calculated landscape connectivity indices based on graph theory to quantify the effect of further agricultural expansion on ecological connectivity at the landscape scale. We used a multicriteria decision analysis that integrates graph-based connectivity indices at the habitat patch scale, combined with an index of human disturbance to identify patches that, if conserved and restored, preserve the connectivity of the landscape most effectively. In the period studied, agriculture increased at a rate of 2104 ha/year, while native Caatinga vegetation decreased at a rate of 5203 ha/year.

Abstract

The residential reuse of greywater has attracted interest in recent years as a strategy to face water security problems. Nowadays, some cities such as Santiago de Chile are seeking to promote new laws that allow residential
greywater reuse and make the incorporation of the necessary infrastructure (machinery and a parallel pipe system) mandatory for new buildings. The success of any such schemes, in terms of the amount of mains water that can be saved, is clearly influenced by the decision that individual consumers make on whether or not to use the parallel system, as they will also be the ones to face the potential externalities produced by the system (e.g., odours, noise from technology).

Abstract

La Patagonia chilena representa hoy una oportunidad única a nivel nacional y mundial de generar un sistema integrado de protección costero-marina de gran valor para la conservación de la biodiversidad y para la sociedad. Con el objetivo de conocer los avances y desafíos en la materia, se describe la evolución, situación actual y las principales características geográficas de las figuras de protección costero-marina. Actualmente, la cobertura de Áreas Marinas Protegidas decretadas, excluyendo las que forman parte del Sistema Nacional de Áreas Silvestres Protegidas del Estado (SNASPE), es de 11.218 km2 (6% de la zona costero-marina patagónica).

Abstract

Los grandes territorios y maritorios de la Patagonia chilena se destacan a nivel global por su alta proporción de áreas protegidas, cerca del 55% del área terrestre y, en términos legales, cerca de 41% de los espacios marinos, aunque parte del reconocimiento y gestión de estos últimos es aún incipiente. También son notables sus parajes remotos de islas y montañas, profusos en atractivos para la recreación y el turismo basado en la naturaleza, junto al alto endemismo de su biota. Los capítulos de este libro documentan los impactos más recientes de la influencia humana (e.g., cambio climático, introducción especies exóticas invasoras, crecimiento del turismo, expansión de la salmonicultura) sobre los ecosistemas patagónicos y resaltan la necesidad de proteger sus excepcionales valores para la conservación regional y mundial. Ante el creciente interés científico por la Patagonia chilena en las últimas décadas, este capítulo resume, a
