BioGaps Transcribe winners for Dec-Jan

The BioGaps top transcribers for the period December to January have been selected:
Well done and a big thank you to volunteer Diana Crane who transcribed 83 specimen label images!

Diana resides in the UK! She as this to say about her transcribing experiences: "I am a retired doctor in my seventies who went to the UK to do postgraduate research in the 1970s, met and married my husband here and never came back. Before leaving I had purchased a life membership of the Botanical Society and I've enjoyed receiving Veld and Flora ever since - I've kept up my interest in conservation.  The BioGaps project seemed like a way to give something back that I can do from the UK: there is something romantic about seeing the specimens, some of them over a hundred years old and getting to see the process of discovering, collecting, naming and classifying in action is fascinating."

Well done Diana! She very kindly has donated her book prize to one of our SANBI interns, which has been given to Ya'qub Ebrahim who works hard in the background with ensuring Transcribe expeditions are activated and also validating transcribed records.

We also awareded a prize to our top SANBI intern transcriber, Mujaahid Philander, who transcribed 52 records. Well done Mujaahid! 

Mujaahid desribes his transcribing experiences as follows: "I am a scientist who loves the "raw groundwork" that feeds into field work in order to discover new things (research). I live quite an active lifestyle, always running or hiking ultimately spending a lot of time in nature.  I started transcribing 5 months ago and with an interest in history it became quite fun. I enjoy the task of transcribing because it allows me to imagine what the environment or habitat looked like when the specimen was found, with the hints provided from the collectors notes. I remember coming across an interesting specimen where the collector recorded that the seeds of the plants was eaten by Bushmen, which I thought was quite a cool story to share with my friends. Overall I enjoy transcribing there is always a story to be told in a collected specimen and with a bit of an imagination you can have quite a bit of fun!!!"

There will be more prizes given for the top transcribers at the end of March 2018. The winners will be announced shortly after the end of each period. Prizes can include books, National Botanical Garden entries, and Kirstenbosch Summer Concert tickets.

We appreciate all the valuable assistance provided by the Transcribe volunteers and SANBI interns! Anyone anywhere can become involved. To join this fun activity, go toTranscribe:

BioGaps digitisers are working hard every day imaging hundreds of plant specimens and their labels. We need all the help we can get in transcribing these records and making them digitially available for research and conservation.

The Transcribe platform helps us fill in gaps in biodiversity knowledge for our precious Karoo region. This information will help guide future conservation and development activities (e.g. shale gas exploration) in the Karoo.

Mammal surveys for BioGaps

By Zoe Woodgate

As we enter 2018 the mammal team has had ample opportunity to reflect on its part SANBI’s Karoo BioGaps project thus far. The two fieldwork leaders for “team mammals”, Nadine Hassan and myself, have been both gathering and analysing data from 25 sites scattered across the karoo over the past year. At the various sites Nadine has been utilising sherman small mammal traps, whilst I’ve been setting up camera traps. Together we hope to create a comprehensive picture of what drives mammal diversity across the karoo.

Whilst we wrapped up much of fieldwork in March 2017, with the final 5 sites to be collected in the upcoming weeks, the experience has left deep impressions upon us. Each farm was drastically different from the next. Since we camped for much of our journey we often privy to majestic vistas. There is something magical about being isolated in the karoo veld, especially after experiencing the cramped city.

Yet the hospitality of the farmers involved in the project cannot be understated. Often we stayed at their personal residences, or were lent a helping hand by an enthusiastic farm manager. One incident stands out above the rest. At a farm nearby Adelaide our 4x4 trailer got stuck in mud after a sudden rainstorm. Unable to delay fieldwork for another day we left it there, vowing to return after completing our planned fieldwork. We arrived at the next farm tired, dirty and miserable. Not only did the trailer contain the various supplies that made living on the road comfortable, it was itself our large tent. We were eternally grateful when the farmer and his lovely wife ushered us indoors to warm beds, coffee and hearty meals.

Happily, all 25 sites have produced beautiful datasets. Nadine in particular has gathered great records of all the small mammal species she encountered. One of her favourite species to encounter was the pygmy mouse (Mus minutoides)- a cute, fluffy little species that never failed to bring a smile to her face. Namaqua Rock Mouse (Micaelamys namaquensis) was one of the more common species, and could be found hiding in the more rockier habitats. Nadine also retrieved samples for further DNA analysis- some of the shrew and mice species are indistinguishable from their morphology.

The (slow) work of camera trapping is also producing interesting results. As is to be expected, several types of domestic livestock dominated the landscape. Sheep, the most commonly farmed animal in the area, were found at over 17 sites. However, despite the large numbers of livestock present, indigenous species occurred across the range in varying abundances. Springbok, kudu, hares and common duiker all made regular appearances.

In the upcoming months not only will we be teasing apart the patterns of species diversity and distribution across the karoo, but also presenting our work at various conferences. Nadine has already attended the Southern African Wildlife Management Association conference in 2017, and her talk was well received.
