A new framework shows how much carbon plants allocate to their endosymbionts and how that amount might change in the face of warming soil and rising carbon dioxide levels.

Old Forests in the Tropics Are Getting Younger and Losing Carbon
New research quantifying the global impact of forest age transitions found that 140 million tons of aboveground carbon are lost per year because of old-growth forests being replaced by younger stands.
Droughts Sync Up as the Climate Changes
A new study reconstructs roughly 800 years of streamflow history in India’s major rivers, showing an increase in synchronous drought linked to anthropogenic climate change.
Primera evaluación a nivel de especies revela riesgo de extinción en Mesoamérica
El 46% de las especies arbóreas de Mesoamérica se encuentran en peligro de extinción. Investigadores esperan que un nuevo estudio regional provea información acerca de estrategias de conservación específicas.
USDA Moves to Rescind Roadless Rule Protecting 45 Million Acres of Wild Area
The U.S. Department of Agriculture (USDA) is proposing rescinding the 2001 Roadless Area Conservation Rule, which protects about 45 million acres (182,000 square kilometers) of National Forest System lands from road construction, reconstruction, and timber harvests.
Waterworks on Tree Stems: The Wonders of Stemflow
Stemflow hydrodynamics offers rich physics that seeks to describe water and matter cycling within the atmosphere-biosphere-geosphere with implications for water resources planning.
Tree Rings Record History of Jet Stream-Related Climate Extremes
Persistent spatial patterns of summer weather extremes in the northern hemisphere recorded in tree ring growth records provide a thousand-year history of jet stream ‘wave5’ dynamics.
Warming Winters Sabotage Trees’ Carbon Uptake
In temperate forests, the biomass-building benefits of warmer growing seasons are offset by damaging variability in winter weather—a disparity that climate models may miss.
First Species-Level Assessment Reveals Extinction Risk in Mesoamerica
Forty-six percent of tree species in Mesoamerica are threatened with extinction. Researchers hope a new regional study will inform targeted conservation strategies.
Artificial Light Lengthens the Urban Growing Season
New research shows that artificial light at night lengthens the plant growing season in cities, overshadowing the effect of high urban temperatures.
