Database of Socio-environmental conflicts and mining tailings in Chile
<p>By searching for protest events in online media, this database was built with 99 cases of protests associated with mining tailings in Chile. It is the first database of its kind in Latin America. It was elaborated under the auspices of the Thesis project to obtain a Master's degree in Political Science at the University of Chile, partially funded by the Center for the Study of Conflict and Social Cohesion (ANID/FONDAP 15130009).</p>
Data from: Abiotic legacies mediate plant-soil feedback during early vegetation succession on rare earth element mine tailings
<p>An increasing number of studies have shown how feedback interactions between plants and soil can influence primary and secondary succession. However, very little is known about the patterns and mechanisms of such plant-soil feedbacks on stressed mine tailings ecosystem, which can be severely contaminated by a range of toxic elements. </p> <p>In a two-phase plant-soil feedback experiment based on the rare earth element (REE) mine tailing soil, we investigated biotic (changes in bacterial and fungal community) and abiotic legacies (changes in chemical properties) of three pioneer grass species, and examined feedback effects of three grasses, two legumes and two woody plants with different root traits.</p> <p>Positive plant-soil feedback was found in Miscanthus sinensis, Paspalum thunbergii and Tephrosia candida, and neutral feedback was observed in other four plants. These effects corresponded with an increase of nutrients and total organic carbon, as well as a decrease of acidity and extractable aluminum and REEs. There were less signs of biotic changes in the conditioned tailings. </p> <p>The correlation analysis suggested a relationship between responses to soil legacies and root traits, as well as root economics spectrum. On the mine tailings, acquisitive species with higher specific root length appeared to have greater potential for positive feedback. </p> <p>Synthesis and application: Our study shows that early succession on contaminated REE mine tailings may lead to more positive plant-soil feedback than predicted based on results of non-contaminated soils, mainly due to the alleviation of abiotic stress in tailings. Therefore, the improvement of specific abiotic soil stress and the trait-based selection of acquisitive plants should be preferentially considered to promote the primary restoration of degraded land.</p>
Root trait values of 11 trees and shrubs grown on mine tailings
<ol> <li>Root traits play significant roles in plant resource-use strategies, and are good predictors of plant growth and survival. However, their predicting role in phytoremediation remains poorly understood and we know much less about the functional covariation of root traits with soil heavy metal (HM) contamination.</li> <li>The objective of this study was to assess the importance of root traits to predict phytoremediation services and to quantify biomass cost (BC) for HM accumulation in eleven woody species grown on a Pb-Zn mine tailing of Southeastern China. Sixteen traits associated with root morphological and chemical features, as well as HM accumulation characteristics, were measured to examine whether there is a RES under HM stressors and whether the covariation among root traits was related to individual or multiple heavy metal translocation and bioconcentration.</li> <li>Our findings provide evidence for a multidimensional RES including one main trend of 'slow-fast' strategy, and a trend representing a trade-off between root system size and root tissue density, indicating root proliferation strategy in a metal-contaminated soil. Another trade-off between root cadmium concentration and root dry matter content implied the existence of a presumable biomass cost for HM accumulation, which was proved to be constrained by RES.</li> <li>Root traits were good predictors of individual or multiple HM translocation and bioconcentration, and linked with phytoremediation services: roots with more acquisitive traits promote HM translocation, whilst conservative roots fostered bioconcentration.</li> <li>This study demonstrates that woody species grown on HM-contaminated soils exhibit different capacities for accumulating or translocating HMs depending on their root system shapes, and their position on the RES. Our results highlighted the importance of root size-related traits in the framework of RES when plants face unfavorable soil conditions and narrow the gap in trait-based ecology. We, for the first time, define and quantify the biomass cost for HM accumulation, providing a better understanding of the resource-allocation theory.</li> </ol>

Database of socio-territorial patterns of mining tailings in Chile
<p>This database originally retrieves information from the Mining and Geology Service of the Government of Chile. Then, it generates a new database from the use of layers with geographic information, specifically, of water courses, localities and infrastructure concentrations.</p>
The first comprehensive revision of all the species attributed to Melomys led J. I. Menzies in 1996 to resurrect the genus Paramelomys and to redefine its morphologicallimits and species content. Menzies created P. gressitti as a new species belonging to a group displaying morphological similarities and including also P. lorentzii and P. moncktoni. Monotypic Distribution. E New Guinea. Descriptive notes. Head-body 135-162 mm, hindfoot 30-34 mm; no specific data are available for body weight. Gressitt's Mosaic-tailed Rat is a medium-sized Paramelomys with a soft, thick and woolly pelage, a long narrow foot, and a tail with three hairs per scale. It exhibits a medium-sepia dorsal pelage and a gray-buff ventral one. Tail is slightly shorter (99%) than head-body length. The skull has a narrow zygomatic plate. Habitat. Moist tropical mountain forest between 2300 m and 2400 m. Food and Feeding. No information. Breeding. No information. Activity patterns. Gressitt's Mosaic-tailed Rat is terrestrial. Movements, Home range and Social organization. No information. Status and Conservation. Classified as Endangered on The IUCN Red List owing to its small geographic range (less than 3500 km?*) and the destruction ofits habitat by mining and logging activities. The major threat to Gressitt's Mosaic-tailed Rat is ongoing habitat degradation caused by nearby human populations; habitat on Mount Kandy has been destroyed by gold-miners and wood-cutters.
