Why tropical grasslands are the most biodiverse environment in the world
Tropical grasslands in the tropics are among the most diverse environments in the Earth’s biosphere, with an estimated 100 million hectares of grasslands across more than 160 countries.
But they are also the most ecologically fragile, and climate change is expected to accelerate the loss of many of these habitats.
In a new study published in the journal Science, a team of scientists from the University of California, Berkeley, found that climate change and changes in rainfall patterns could drive the loss and degradation of tropical grasses, as well as other plant and animal life in the area.
“We found that as climate change intensifies, it’s likely that tropical grassy areas will become more ecologically vulnerable to climate change, as climate-related stresses, like drought, will accelerate the erosion of these grasslands,” said lead author Rui Irigaray, a postdoctoral researcher at the Berkeley Lab’s Earth and Atmospheric Sciences.
“Our findings provide important information about how the climate is changing in tropical grass habitats and their potential impacts on ecosystems and species in the region.
In addition, we found that the number of areas in which tropical grass species are threatened is increasing.
For example, in countries like Brazil, the number is increasing in some areas.””
This is one of the first studies that looks at tropical grass ecosystems and the impacts they have on biodiversity,” said Iriga, who is also a professor of Earth and Environmental Sciences at the UC Berkeley School of Earth, Energy and Environmental Science.
“We found significant changes in the distribution of tropical species and a significant increase in the risk of loss.”
Irigalay and his colleagues surveyed tropical grass areas in the Andes, the Amazon, the Andean region of South America, and Ecuador.
Their findings showed that while most tropical grass lands are in temperate latitudes, their distribution is dominated by tropical species, particularly grasses like cassava, grasses that are common in areas with cooler temperatures, like the Amazon.
Andean grasslands and their temperate zones are home to several species of plant and animals, including the iconic cassava.
Irigaro’s research showed that increasing temperatures in temperating regions, such as Brazil, are affecting plant and plant-animal life, and the loss will be severe.
The team also found that in areas that have a high percentage of temperate species, such areas have fewer grasses than in areas in temperates.
“In other words, the species that are most sensitive to climate variability are in the temperate areas,” Irigario said.
The researchers found that, in some temperate grasslands, the change in climate was as big as 10 degrees Celsius, which would lead to the loss or destruction of at least 1 million hectares in a year.
“There are some areas where the temperature change has been more than 10 degrees,” Iritario said, adding that these areas would be at greater risk of being lost.
Climate change is already affecting grasslands around the world. “
A lot of the changes we see in temperatides are related to the changing climate, so there is a lot of concern about the impact on biodiversity.”
Climate change is already affecting grasslands around the world.
A report from the Intergovernmental Panel on Climate Change in 2014 estimated that global grassland areas lost around 8 million hectares by 2050, with more than half of this loss in temperatal areas.
In many areas of tropical America, the drought is increasing the vulnerability of tropical vegetation to changes in precipitation, with grasslands often being the first to be affected.
Climate change could exacerbate this trend, the researchers warn.
“We are going to see the most dramatic change in tropical areas that we have ever seen,” Iriroquia said.
“They will be the most vulnerable.”
