Introduction
I am interested on forest dynamics linked to global environmental change, particularly with invasive species. Currently, I´m working in adaptive management of trees in a subtropical forest, within the CONTAIN project.

demonstrated that individuals growing in shrublands have a higher fecundity than those in grassland and rocky habitats. Furthermore, grazing pressure of cattle and horses substantially reduces fecundity and impacts the relationship between age and fecundity. We incorporated our field-estimated habitat and age-specific fecundities into both analytic...

Formulating effective management plans for addressing the impacts of invasive non-native species (INNS) requires the definition of clear priorities and tangible targets, and the recognition of the plurality of societal values assigned to these species. These tasks require a multi-disciplinary approach and the involvement of stakeholders. Here, we d...
Article
Effective long-term management is needed to address the impacts of invasive alien species (IAS) that cannot be eradicated. We describe the fundamental characteristics of long-term management policies for IAS, diagnose a major shortcoming, and outline how to produce effective IAS management. Key international and transnational management policies co...

Seventy-five percent of the human population will live in urban areas by 2050, and urban vegetation will be the main source of ecosystem services. Unequal access to urban vegetation might exacerbate existing socioeconomic differences. Studies performed in cities of developed countries show that the population with higher socioeconomic status has mo...

Invasive Alien Species (IAS) threaten biodiversity, ecosystem functions and services, modify landscapes and impose costs to national economies. Management efforts are underway globally to reduce these impacts, but little attention has been paid to optimising the use of the scarce available resources when IAS are impossible to eradicate, and therefo...
Article
Urbanization is causing profound alterations of ecosystem functions at local and regional scales. The need to maximize ecosystem services to improve the livability of cities is resulting in intensive management of urban vegetation, which is likely generating new conditions for the ecosystem functioning. In this paper, we address the association bet...

En Argentina los sistemas silvopastoriles en bosque nativo son el método productivo más establecido en zonas amarillas desde la implementación de la ley de ordenamiento territorial. Aunque estos sistemas podrían ocupar 14 millones de hectáreas en el futuro del Chaco Seco, aún no se han documentado los efectos a escala regional del manejo silvopasto...
Article

Dispersal abilities of invading species emerge from the interaction between the species and some features of the target community. Ligustrum lucidum is a tree species invading different ecosystems. Major spatial patterns of Ligustrum invasions and their ecological consequences have been analyzed, but no study addressed the dispersal process at a fi...

Silvopastoral systems (SPS) provide a wide range of non-provisioning ecosystem services including carbon (C) sequestration. Well-managed SPS outperform both grasslands/pastures and forests in terms of C by increasing soil and biomass C storage. In this Chapter, C sequestration information from native forests and tree plantations under silvopastoral...

Ligustrum lucidum, native of China, is one of the dominant exotic and invasive tree species in secondary forests in Argentina. 1) We assessed its invasion during 20 years in post-agricultural secondary forests dominated by native tree species, and 2) evaluated tree demographic rates of native individuals under and away from L. lucidum trees that in...
Article
The Dry Chaco is one of the most active agriculture frontiers, which imposes trade-offs and synergies among ecosystem services (ES). Most studies analyze real or potential supply of ES associated to land use change; but they usually neglect ES social demands. Interviews to inhabitants of small urban centers in the Argentinean Dry Chaco revealed tha...

Una de las medidas de mitigación del cambio climático más fomentadas es el secuestro de carbono por vegetación. Esto depende de la velocidad de captación y transformación del carbono en biomasa, velocidad de liberación a través de la respiración y estabilidad del stock ante disturbios. La diversidad forestal influye sobre estos factores, cuya efici...

Ligustrum lucidum es una especie exótica que está invadiendo fuertemente las Yungas Australes de Argentina, presenta frutos con pulpa carnosa que proporcionan alimento de aves que al ingerirlos dispersan sus semillas. Generalmente las aves frugívoras consumen completos los frutos y posteriormente sus semillas son defecadas o regurgitadas. Mediante...

The growing global demand for food, production technology and market competitiveness require intensification of agricultural activities and land abandonment and agricultural livestock marginal unproductive. Consequently there is a change in the land use changes hauling socioeconomic, cultural and environmental. The Valle de Tafí (Tucumán, Argentina...

Two effective and low-cost methods that can be easily applied in areas with low resources that do not have access to a drinking water network are the methods of Solar Disinfection by Photolysis (SODIS) and Solar Heterogeneous Photocatalysis (SHP) with TiO2 as catalyst. This work included the development of new studies to validate both technologies...

Project
This ambitious, international project aims to preserve biodiversity, ecosystem services and livelihoods by improving the strategic, long-term management of damaging invasive non-native species (INNS) that cannot be eradicated and must be managed in perpetuity. The project levers existing high quality ecological data on animal and plant invasive species already acquired by LATAM project members, together with targeted new data collection (including from experimental control), and integrates this with state-of-the-art modelling approaches developed by the UK project members in order to deliver novel tools and approaches that can inform the effective management of INNS in the region.
