Had a lot of fun presenting first results of my postdoctoral project at #ESHE2025 beginning to explore chimpanzee rock climbing in the wild 🧗‍♀️🙉
collab w/ @gmerc-tz.bsky.social @mbchimp.bsky.social
Excited for the next steps, watch this space!

Rhianna Drummond-Clarke ‘First documentation and quantification of wild chimpanzee rock climbing’
Camera traps, Issa Valley TZ & Moyen Bafing, Guinea chimps

Rock vs tree climbing: more dynamic movements, biomech diff locomotor modes, reaching further- role of uneven substrates!
Amazing 😍

Foraging strategy and tree structure as drivers of arboreality and suspensory behaviour in savannah-dwelling chimpanzees 🏺🧪

Finds arboreal, especially suspensory locomotion can be advantageous for foraging in a savannah-mosaic and not just closed forest habitats
The Issa Valley study site. (A) Location in Tanzania and vegetation map. (B) An example of typical riparian forest vegetation at Issa during dry season (note dry river bed but evergreen vegetation). (C–E) Examples of typical miombo woodland vegetation during dry season at Issa. Woodland trees lose their leaves (C, D), grass dries and is burnt by fires. The woodland undergoes regeneration with regrowth after fires (E). Photo credits RCDC/GMERC.

Great coverage by @primatology.net, too! If your eyes need a break they have an audio deepdive that discusses our findings really nicely 🐵🌳

New study on Issa Valley chimpanzees shows bipedalism may have evolved in trees, not just on the ground. Foraging needs in open woodlands kept apes climbing. Rethinking human origins? 🐒🌳 #HumanEvolution #Primatology #Anthropology #Archaeology #Bipedalism

Thank you for sharing my work :) I love the audio deepdive!

So happy to have this final chunk of my phd out, and the fruits of my @leakeyfoundation.org research grant 🙉

Frontiers | Foraging strategy and tree structure as drivers of arboreality and suspensory behaviour in savannah-dwelling chimpanzees
IntroductionThe association between an open habitat (e.g., savannah-mosaics) and increased terrestriality is central to hypotheses of hominin evolution, espe...

Coverage of my findings on chimpanzee arboreality in a savannah-mosaic in @sciencedaily.com.web.brid.gy. The need to safely access food at the ends of thin branches may have been the driving force for bipedal, and suspensory, behaviour to evolve in open habitat.

Our newest issue is now live! On the cover a female killer whale grasps a floating stalk of bull kelp as observed by @drwhale.bsky.social and colleagues, utilizing these during tactile social interactions, potentially as a form of tool-assisted allogrooming. www.cell.com/current-biol...

🌳🦍 NEW PUBLICATION 🦍🌳

In the first study of gorilla arboreality outside of Virunga, we recognise the importance of arboreality for gorillas, with big implications for understanding their anatomy, ecology and making evolutionary inferences from gorilla-like morphology in the fossil record.
Gorillas are arboreal apes
There is debate over the importance of the arboreal niche in hominid evolution.1,2,3,4,5,6 Gorillas are considered to be primarily terrestrial,7,8,9,1…

Had a lot of fun working on this, thinking more about the other African ape 🦍 and bringing trees to the forefront of great ape evolution some more 🌳

Do chimpanzees use the onset of rains as indicators of termite fishing season? At Issa they do! Team Phillips, Oelze et al. strike again!

Bird scavenging (or hunting?!) - add it to the diet list! Great capture, @R. Drummond-Clarke!. Extra points for anyone who can identify the bird species!
