As oceans warm and become more acidic and oxygen-poor, Smithsonian researchers asked how marine life on a Caribbean coral reef copes with changing conditions.

Helene Muller-Landau, staff scientist, was invited to write an authoritative review about carbon storage in forests. Her team combed through existing studies and came up with some novel conclusions of their own.
Lightning is common in the tropics, but its ecological effects in tropical forests are poorly understood. Steve Yanoviak, STRI research associate and professor at the University of Louisville, will summarize the basic physics of lightning, how we study lightning in Panama and the importance of lightning as an agent of tropical tree mortality.
Scientists think that climate change may have greater impact the largest trees in tropical forests, and the death of these giants has a major impact on the forest, but because these monumental trees are few and far between, almost nothing is known about what causes them to die.
The Fortuna Forest Reserve in western Panama hosts some of the most diverse montane forests in Central America. Jim Dalling, STRI Research Associate, will discuss the results of 25 years of research on Fortuna's climate, geology, soils and major plant groups, including more than 800 species of trees, 300 species of ferns and 200 species of orchids.
The Fortuna Hydrological Reserve hosts one third of Panama’s tree species, a variety of fungi waiting to be discovered and a great potential to offset global warming
The Barro Colorado bird community has lost about a quarter of its species over time
The accelerated proliferation of these woody vines, due to natural disturbance, is altering forest structure, regeneration and functioning
Deforestation scenarios show the importance of secondary forest for meeting Panama’s carbon goals.
Understanding when and where trees die in vast tropical forests is a challenging first step toward understanding carbon dynamics and climate change. Researchers explained variations in tree mortality over a five-year period by analyzing drone images of one of the most-studied tropical forests in the world, Barro Colorado Island in Panama.
