Protecting the Guardians of Biodiversity

Deforestation, wildfires, and climate change are some of the main factors threatening the health of forests in today's world. Through monitoring systems, specialists from CONICET study their dynamics and evolution with the aim of preserving them for the future.  

Soil organic carbon stocks in native forest of Argentina: a useful surrogate for mitigation and conservation planning under climate variability

This study models soil organic carbon (SOC) stocks in Argentina's native forests and links them to biodiversity concerns amid climate variability. It finds significant SOC variation influenced by regional climate factors, offering insights for forest management and biodiversity resilience efforts within the Kyoto Protocol and REDD+ framework.

What is the economic cost of biological invasions in our urban environments?

Biological invasions in urban areas resulted in a total cost of US$ 326.7 billion between 1965 and 2021. Urban costs represent approximately 15% of the total costs caused by invasive species. 61 invasive species are associated with costs in urban areas of 24 countries. 73 countries have occurrences of costly invasive species in urban areas, yet no monetary costs have been reported.
