Riverbank erosion in SW Australia exposed previously undocumented root clusters in Kingia australis. Research by Lamont et al. suggests these novel 'kingioid roots' enhance water and nutrient uptake rather than storage, linking with seasonal root-cluster types🫚 Paper here 🔗 buff.ly/Hi3BxLE
A dense, intricate cluster of golden-brown roots and rootlets from the grasstree Kingia australis, displayed against a white background. The cluster shows a complex branching structure with a main parent root extending horizontally, from which hundreds of fine secondary roots and rootlets emerge in all directions, creating a dense, bushy appearance.

The text on the image reads: "An eroding riverbank exposed the hidden root systems of the grasstree, Kingia australis."

There is a huge need for more research on pollination in native species and support for existing work. Collection of baseline data is crucial as is monitoring already threatened species. There may also be unexpected impacts arise through interactions with other threats like fragmentation or fire 3/5

We found a decline in feral honeybees will be good news for some plants and bad news for others. But we found major gaps in our knowledge of how honeybees influence native plant pollination and pollinators. The loss of feral honeybees due to varroa mite is an opportunity to fill these gaps 2/5
