Our new article in Life (MDPI) explored the vulnerability of caves inhabited by bats to anthropogenic disturbances. We found most caves in Mount Elgon (areas of Uganda) are utilized by human communities for a wide range of purposes. #bats #OneHealth. @MDPIOpenaccess

Baobab trees provide fruit, fibre, medicine and shelter for people & wildlife. Their survival depends on pollination by bats & moths. While these trees can cope with a wide range of environmental & climatic conditions, bats and moths may be more susceptible.

You can now pass random variables to any aesthetic in any ggplot geom/stat. If you can express it as a distribution, ggdibbler can plot it. It also works with ggplot extensions, like gganimate. #rstats
