Although I have moved into a very different field – working in marine chemistry, and chasing new molecules from the sea, these days – I will always have fond memories of my days following the Bwindi gorillas (and collecting their food plants and poo). I do even still get the occasional inquiry about Aframomum and gorillas.

I was down there between 1995- 1997, when working on my PhD research which focused on the chemistry of the Mountain Gorilla diet, and particularly the possible role of some of the antimicrobial components of their plant-based diet in relation to their enteric microflora (i.e. bacteria in their guts).  In part, this evolved out of an interest in “zoopharmacognosy”  - or the use of plants, and their chemistry, by animals for self-medication -  and in some cases, the food items (e.g the bark of Dombeya) which contained the antimicrobial metabolites were apparently eaten/used primarily when the gorillas showed signs of gastrointestinal illness (based, at least, on the observation of the trackers).  More generally though, I showed interesting patterns/correlations of apparent sensitivity and resistance to antimicrobial components relative to their consumption of these plants/food items.  In particular, this difference was based on range (i.e. Comparison between the lower elevation Buhoma and higher elevation Ruhija).

I (still) have (this) photo on my office desk. Ah, the good old days down at the swamp!


This was when we were following a gorilla group being habituated by ITFC (starting around 1994-1995).). By the time that I was finishing 1997, they were actually quite accustomed to seeing us.





One amusement to share from the times:

Aaah, there were many, but I have to say the top two that pop to mind had to do with being in the field with the gorilla group during their habituation. 
I vividly recall all of us squatting in the bush alongside the (gorilla) group pretending to be fellow (apparently hairless) gorillas to put them at ease with our presence – this, of course, involved pretending to chomp on leaves, and mimic their constant grunts and farts.  Glamorous stuff!
I also will always remember one of the more dominant females running past me, as she left and snapping a 10-cm wide branch in front of my face – presumably to let me know that it could have just as easily been my neck.  That sort of stuff sticks with you.
