They mostly comprise of undisturbed environments which provide important ecosystem services, including carbon sequestration, water reservoir and habitat for both widespread and endemic organisms. When compared with boreal peatlands, our knowledge of the functioning of SSAP is poor, and it is necessary to raise awareness about their scientific and ecological value and to ensure their conservation. This article examines a broad base of historical and contemporary published research literature on the peatlands of Chile and Argentina, from 1843 onwards, to identify gaps in knowledge, implications for the assessment of peatland functioning, and targets for peatland conservation and management. To achieve this goal, we reviewed a total of 196 research papers/reports from across the peer-reviewed and grey literature. We conclude that gaps in our knowledge and understanding of SSAP have deeply ...

Our expedition showed that Peninsula Mitre hosts a wide variety of habitats across two exciting ecological gradients: (i) a regional west–east gradient from Sphagnum magellanicum dominated mires in the west to Astelia pumila dominated mires in the east; and (ii) a gradient from extremely acid to extremely carbonate rich mire types induced by local bedrock. The large variety of hydromorphological mire types comprises raised bogs, blanket bogs, sloping fens, string fens, flat fens and calcareous spring fens. In the Atlantic coastal area, the abundance of Sphagnum magellanicum in the ombrogenic systems decreases conspicuously from west to east with the species being almost absent in the east. H...

The group considered the vegetation, hydrology, peat stratigraphy and possible management options for about 20 mires which were visited during a seven-day excursion. We report here some field observations and measurements of electrical conductivity (EC 25) in five mires which have been selected to encompass the most important ecohydrological features of the mires of Tierra del Fuego. Existing and new data on landscape topography and vegetation were combined in threedimensional drawings. These drawings are actually conceptual models which could underpin further ecohydrological research, and proved to be very useful as a basis for discussions amongst conference participants about possible ecohydrological relationships. The mires that were studied developed under a wide range of climatic conditions and included fens and bogs. The bogs typically developed from lakes or fens and most are now dominated by Sphagnum magellanicum. This species forms large hummocks, and can invade weakly-buffered fens. Most of the mires were well preserved, but effects of human impact-such as road building and peat extraction-were also noticeable.

Ecosystem Services in Patagonia, 2021

The objective of this chapter is to review the state of knowledge about the ES of Patagonian peatlands and the related processes that explain them. Some of these services, such as carbon storage, carbon sink, flood control, and water supply, are outcomes of complex biotic and abiotic interactions that take place in these ecosystems. We identified and classified ES of Patagonian peatlands in nonmonetary terms, following the guidelines of the Common International Classification of Ecosystem Services (CICES) V5.1. Different peatlands may contrast in the quality or essence of respective ES; therefore, the analysis of the ES significance requires information from local studies based on scientific knowledge and field data. We supply evidence obtained from study cases and discuss the accuracy of curren...

There are many questions to deal with, such as geographic representation of environmental variables, large timeseries management, measurements and observations related with different hydrologic phenomena recording and the integration of simulations models to information systems. Conceptual models allow us to understand and simplify problems in a specific domain. These problems can be expressed through analysis patterns, which reflect conceptual structures of an application domain speeding up the development of the abstract analysis model. This model will be able to capture the main requirements from real world problems. This type of patterns, are used in the present paper to define conceptual microarchitectures that allow the appropriate representation of environmental informat...

El software del dominio no cuenta con herramientas adecuadas para facilitar integracion, reuso y manejo de la complejidad en un nivel de abstraccion apropiado. El modelado especifico del dominio (DSM) propone elevar el nivel de abstraccion, expresando las soluciones directamente en terminos del dominio. Es muy conveniente para sistemas complejos y para desarrollo de modelos flexibles y reusables en dominios acotados. En esta linea de investigacion se propone el estudio y desarrollo de DSLs para familias de aplicaciones en el dominio MSA, definidas mediante un enfoque de reuso sistematico de software, con facilidades para integracion de modelos multidisciplinarios. Se presentan los estudios realizados en la primera etapa de la linea de investigacion, durante la cual se analizaron los req...
