#Vines choke a forests ability to capture carbontropical forests are a sometimes-underappreciated asset in the battle against climate change.
New research by Smithsonian scientists shows increasingly abundant vines could hamper this potential and may even cause tropical forests to lose carbon.
In the first study to experimentally demonstrate that competition between plants can result in ecosystem-wide losses of forest carbon scientists working in Panama showed that lianas
or woody vines can reduce net forest biomass accumulation by nearly 20 percent Researchers called this estimate conservative in findings published this month in Ecology.
This paper represents the first experimental quantification of the effects of lianas on biomass said lead author Stefan Schnitzer a research associate at the Smithsonian Tropical Research Institute and professor at the University of Wisconsin-Milwaukee.
As lianas increase in tropical forests they will lower the capacity for tropical forests to accumulate carbon.
Previous research by Schnitzer and others demonstrated that lianas are increasing in tropical forests around the globe.
Decreased rainfall is one suspect but lianas which are generally more drought-tolerant than trees are increasing in abundance even in rainforests that have not experienced apparent changes in weather patterns.
Lianas climb trees to reach the forest canopy where their leaves blot out the sunlight required for tree growth.
Machetes in hand Schnitzer and colleagues chopped lianas out of forest plots for this study. After collecting eight years of data comparing liana-free plots with naturally liana-filled plots in the same forest they quantified the extent to which lianas limited tree growth hence carbon uptake.
In gaps created by fallen trees lianas were shown to reduce tree biomass accumulation by nearly 300 percent.
Findings by Schnitzer and colleagues also published this year in Ecology showed that liana distribution
and diversity are determined largely by forest gaps which is not the case for tropical trees.
The ability of lianas to rapidly invade open areas and young forests may dramatically reduce tropical tree regeneration
Lianas have been shown to consistently hinder the recruitment of small trees and limit the growth fecundity and survival of established trees.
because lianas prevent trees from accumulating vast amounts of carbon but lianas cannot compensate in terms of carbon accumulation said Schnitzer.
If lianas continue to increase in tropical forests they will reduce the capacity for tropical forests to uptake carbon
which will accelerate the rate of increase of atmospheric carbon worldwide. Story Source: The above story is provided based on materials by Smithsonian Tropical Research Institute.
The combination of selective logging and wildfires damages turns primary forests into a thick scrub full of smaller trees and vines which stores 40%less carbon than undisturbed forests.
and liana species observed in the feeding experiments. This suggests that the number of types of damage seen in the fossil record is also related to the actual diversity of damage-making insects.
