High species richness of sheep‐grazed sand pastures is driven by disturbance‐tolerant and weedy short‐lived species

Ecology and Evolution, Volume 14, Issue 9, September 2024.
We analysed the fine scale biomass patterns of sheep‐grazed sand pastures along increasing grazing intensity. Along the grazing intensity gradient, we found an increasing trend for species richness and the biomass of short‐lived forbs; while green biomass, litter and graminoid biomass showed a decreasing trend.

Promotion of Circular Economy: Steelwork Dusts as Secondary Raw Material in Conventional Mortars

Proceedings, 2018
Among the actions proposed by the European Union for the implementation of Circular Economy is the use of waste as a secondary raw material (SRM). During the fusion of the scrap, a steel dust is generated, named Electric Arc Furnace Dust (EAFD). The EAFD

Accumulated soil seed bank of the invasive sand dropseed (Sporobolus cryptandrus) poses a challenge for its suppression

Land Degradation &Development, Volume 35, Issue 13, Page 4105-4120, 15 August 2024.
Abstract Global warming, elevated atmospheric CO2 concentrations and increased likeliness of extreme drought and wildfires in many regions will likely favour C4 grass species. To support future management actions, we explored the effect of the encroachment of an invasive perennial C4 grass, Sporobolus cryptandrus on the composition of soil seed banks ...

Comparative study of selective zinc leaching from EAFD using carboxylic agents

Revista Mexicana de Ingeniería Química, 2020
Recycling of industrial waste has become a process of highly positive impact on the environment, industry and human health. The management of the electric arc furnace dust (EAFD) is a necessary and interesting task due to the possible recovery of its elevated metallic content (Zn, Pb, Cu, etc.). This reduces the environmental pollution generated by the
