From field mouse to lab rat

After spending about 300 days in the field, I returned to civilisation enriched and ready to tackle the next challenge on my journey as a PhD student. I had learned new skills, habituated foxes and picked up a substantial amount of poop, but I was VERY happy to return to a place where I could drive down the road for a supersize BigMac with Fanta whenever the cravings hit.

Labwork, beautiful, endless labwork

However, I realized again there is no rest for the wicked as I started my lab work. For endless weeks it was my fate to be drying faecal samples, pulverising dried pellets and finally extracting the hormones, getting used to a brand new routine (working by daylight, instead of starlight).

Who knew that returning to Pretoria and doing lab work would isolate me more than being in the field? I would drift away into my own poop-filled world before the distinctive aroma of carnivore faeces shocked me back to reality. After a few monotonous weeks of solitary extractions, I was surprised to find a friend from Zurich visiting the lab for a few days. Through all the gossip catch-up and b(sh)anter we bounced ideas off each other before he made his long journey back home. I was alone again and focussed to get the job done as the end slowly crept closer.

Before I could close the lab door behind me, I had to burn my samples to complete the process. Nothing prepared me for the smell of burning bat-eared fox poop at 450°C.

Protection is essential in the lab.

I am sure I was the most unpopular person in our entire building as the smell of smouldering organic matter overtook us all, filling the halls with a lingering odour. It was all worth it in the end when, after 14 months of sweat and stress, I was holding the newly extracted (non-smelly) hormones in my hand.

As I carefully store all the tubes of extract, I realise that these little tubes will make up a substantial part of my PhD thesis (and future). I now have to wait a few more weeks before I get the final faecal samples from the field. Once I’ve finished the preparatory lab work, I can finally start the analysis of my hormone samples. I miss the field; watching the sun set as I head out for the night and, sometimes, watching the sun rise after spending the entire night observing foxes. I thought I would return to civilization with a bronze glow; alas, I extensively worked on my moon tan and it seems I will continue doing so as I will spend all my time in the lab, until the end of my PhD.

After 8 months and a rocky start, we’ve finally done it!
It all began in November 2013 when I began my quest to find my new study species, the very cute and relatively unstudied bat-eared fox. Living in the middle of a Nature reserve with no electricity, having to climb a mountain to get a few bars of cell phone reception, started taking its toll after a few weeks. The only social interaction I had was with the staff on the reserve and the monkeys who kept trying to steal my food. After three weeks without a single fox sighting in a place supposedly “crawling with them”, we decide to cut our losses. We’d start afresh in the new year…and what a start it was! I arrived in the Kalahari in a bakkie with no radio and no air conditioning. The clouds gathered in the distance and I celebrated as I felt the raindrops on my skin, cooling me as I drove the next 100km. The first day I went into the field, I was ecstatic when only after one hour, I saw my first two bat-eared foxes resting at their den! It all just starte Continue reading
