A view from a different angle: investigating the significance of tattan spines from a small mammals’ visual point of view using imageJ

Rattans are one of the most unique and economically important plants for most tropical countries. There is however, a lack of interest in the specific study of the rattan spines. In this paper, we tested a new hypothesis concerning the functional role of rattan spines. We proposed that rattan spines...
