The Iberian Ecological Society SIBECOL has just been established to gather professional scientist from Portugal and Spain from all ecology areas: theoretical, terrestrial, marine and continental waters. Its main aim is promoting ecology and to give visibility to scientific works in all these fields.

To celebrate the establishment of the society and to share the scientific progress in ecology, last 4th -7th of February the First SIBECOL Congress, as well as the XIV AEET Meeting, were celebrated. The venue selected was the Faculty of Biology at the University of Barcelona (Spain).

This congress was celebrated in an emblematic time and place due to the commemoration, this year 2019, of the centenary of Professor Ramon Margalef. Margalef became one of the most relevant ecologist of the XX century and the first professor of Ecology in Spain at the University of Barcelona, where all the Iberian ecologist had the opportunity to meet.

INTARSU Project did not want to miss this important event for ecology and we had the opportunity of presenting our last study in a poster titled: “Phytostabilisation of trace elements with different tree species revealed a species-specific effect on soil functioning”. This work has been possible thanks to the collaboration between researchers from IRNAS-CSIC, University of Sevilla and University of Reading (United Kingdom). The poster was presented in the Thematic Session 14 “Organisms and ecosystem responses to global change in soils and sediments”, organized by the Group of Plant-Soil Interactions of AEET.

In this study, we presented the effects of different tree species (white poplar, wild olive and stone pine) on biotic and abiotic soil properties. The study area, known as Guadiamar Green Corridor (Seville), suffered in 1998 a serious contamination due to Aznalcóllar mine-spill. After a remediation plan in the whole affected area, different tree and shrubs species were planted, and 15 years after these trees have generated soil changes. In relation to soil nutrients, we have found that the tree coverage has increased fertility in soils underneath compared to soils covered by herbaceous plants. Among the studied species, white poplar trees have helped to neutralize soil pH; however, stone pine trees have acidified the soil which is undesirable as acidity increases soil trace element availability. Soil microbial activity presented differences among tree species and we found that enzyme activities with an important role in C, N and P cycles were highly dependent on soil pH. To summarise, we have found a tree species effect on abiotic and biotic soil properties with direct consequences on soil functioning.
