We review information on salmon farming production, environmental and climatic variables covering all salmon farming areas in the Patagonia marine ecosystems over a 10‐year period in Chile. With this information, we develop a semi‐quantitative Environmental and Productive Risk Assessment (RA) model as a guide for the design of a Traffic Light System (TLS) for salmon farming in Chile that ensures the minimizing impacts to ecosy...
Geography and ecology shape the phylogenetic composition of Amazonian tree communitiesNARA Subscribed
Aim Amazonia hosts more tree species from numerous evolutionary lineages, both young and ancient, than any other biogeographic region. Previous studies have shown that tree lineages colonized multiple edaphic environments and dispersed widely across Amazonia, leading to a hypothesis, which we test, that lineages should not be strongly associated with either geographic regions or edaphic forest types. Location Amazonia. Taxon A...
Geographic patterns of tree dispersal modes in Amazonia and their ecological correlatesNARA Subscribed
Aim To investigate the geographic patterns and ecological correlates in the geographic distribution of the most common tree dispersal modes in Amazonia (endozoochory, synzoochory, anemochory and hydrochory). We examined if the proportional abundance of these dispersal modes could be explained by the availability of dispersal agents (disperser‐availability hypothesis) and/or the availability of resources for constructing zoocho...
Global maps of soil temperatureNARA Subscribed
Research in global change ecology relies heavily on global climatic grids derived from estimates of air temperature in open areas at around 2 m above the ground. These climatic grids do not reflect conditions below vegetation canopies and near the ground surface, where critical ecosystem functions occur and most terrestrial species reside. Here, we provide global maps of soil temperature and bioclimatic variables at a 1‐km 2 r...
Environmental issues in Chilean salmon farming: a reviewNARA Subscribed
The growth of Chilean salmon production has not been free of important sanitary and environmental shortcomings. To ensure sustainability, it is necessary to understand the environmental impacts of salmon production on the Patagonian ecosystems. Currently, there is limited regulation or monitoring of impacts in the freshwater phase compared to the marine fattening stage, and there is some evidence of local eutrophication impact...
Modelling the role of Atlantic air–sea interaction in the impact of Madden–Julian Oscillation on South American climateNARA Subscribed
This study addresses the role of Atlantic air–sea interaction in the remote influence of the Madden–Julian Oscillation (MJO) on eastern South American climate during austral summertime. To disentangle the different processes involved, reanalysis data as well as a regional climate model run in coupled mode and as a stand‐alone atmosphere are used. The simulations are able to represent the observed influences of the MJO in preci...
