Driftwood Flow Disruption Affects Marine Ecosystems • Earth.com

Throughout history, rivers have carried a large amount of driftwood to the oceans. However, humans all over the world are increasingly interfering with this process. New research from Colorado State University (CSU) has found that disrupting the flow of driftwood from rivers to oceans can have a significant impact on marine ecosystems. “Dead trees, known […]

Protect ecosystems first for maximum carbon storage, study finds

When it comes to slowing down climate change, there is a natural solution that has recently taken hold of the world: large-scale tree planting and reforestation. But a new study warns that other natural climate solutions should be considered first. By comparing different natural climate solutions according to four criteria, the study proposes a hierarchy: […]

Invasive ants can threaten ecosystems by damaging plants at the root

Fathead ants reduce carbon sequestration, root and leaf production, leaf water status, and soluble sugar concentrations in the woody tissues of young acacia trees by digging nests around the roots of young trees. . Young trees already have extremely low survival rates to maturity, so this invasive ant will likely reduce the population growth rates […]

Growing forests can help heal tropical aquatic ecosystems: study | News | Eco-Enterprise

Scientists have long identified a link between livestock production and deforestation, with extensive research showing the detrimental effect of agricultural activities on natural resources. However, little is known about the impact of these practices on water microbial communities – the tiny organisms that maintain water quality by cycling nutrients and energy. A new study published […]

Young forests can help heal tropical aquatic ecosystems: study

Microbial communities are important indicators of ecological degradation in the tropics, often reflecting levels of disturbance and contamination of rivers and streams. To monitor the ecological status of various waterways in central Panama, researchers from the Smithsonian Tropical Research Institute (STRI) assessed the impact of various land uses, such as livestock grazing and secondary forest.
