Rufford je odlična prilika da se dobije mali grant, pošto u fokus stavlja slabije razvijene zemlje (neka vajda i od nerazvijenosti). I dosta su im fleksibilni uslovi trpšenja: https://apply.ruffordsmallgrants.org/

Ove oči vide odlično, a naučnici tvrde i da razlikuju boje i vide u mraku

Nadjoh nešto novo na ovu temu:

We found that both sexes responded and discriminated equally between different colours, with some differences between flowers and discs. In particular, the red was preferred in the disc experiment, mainly by males, but was disregarded by both sexes in the flower experiment, where red was represented by poppy, Papaver rhoeas. This suggests that Hermann's tortoise probably relies on a mixed system of olfactory and visual abilities to detect food in order to optimize the intake of essential nutrients as minerals or carotenoids.
