The Karoo Predator Project is happy to announce that Wiley has published our research on the dietary niche relationships among predators on farmland and a protected area in the Journal of Wildlife Management. The paper was followed by an article written by David Frey for the Wildlife Society.
Our research shows that black-backed jackals (Canis mesomelas) and caracals (Caracal caracal) can adapt their diet to the land use in which they live. On rangelands, the diet of jackals consists of 42% of small-livestock whereas it consists of 25% of small-livestock for caracals. Interestingly, in a nearby protected area, jackals mostly eat fruit, and caracals micromammals.
Another important finding is that black-backed jackals consume more small-livestock than expected compared to their availability in the landscape on rangelands. We termed this fact “preference”. It is therefore extremely important for small-livestock farmers to protect their sheep on rangelands because of jackals “preference” for livestock over similar-sized wild prey species. However, we would argue that farmers can not bear the full cost of livestock protection and losses alone in South Africa and that assistance from the State and NGOs – like in other countries in the world – is necessary and would improve wildlife and livestock welfare.

As you probably know from a previous blog post, the Karoo Predator Project is involved in some of the assessments for the 2016 Red List of Mammals of South Africa, Lesotho and Swaziland. The project is led by The Endangered Wildlife Trust (EWT) and the South African National Biodiversity Institute (SANBI) and provides an up-to-date assessment of the state of South African mammals, of which 57 (17%) are deemed to be threatened with extinction and 34 (10%) are Near Threatened.
The Karoo Predator Project took part in several of these assessments and the one on black-backed jackal has recently been published.
The other assessments in which the KPP got involved are the caracal, the black-footed cat, the chacma baboon and the grey rhebok ones (national and global).
Enjoy the read!
Last Saturday, Zoe Woodgate, a PhD student working on the critically endangered riverine rabbit across the drylands of South Africa, and Marine Drouilly went to Anysberg Nature Reserve in the Little Karoo to present their respective project and some of their results to the farmers living around the protected area. The meeting was chaired by Marius Brand, Anysberg Nature Reserve’s manager.

It was a great opportunity to exchange with mostly lifestyle farmers this time and we were delighted to see how conservation-minded the whole community was! Both Marine and Zoe were asked lots of interesting questions after their talks.

The Karoo Predator Project would like to thank Cape Nature and Marius Brand for inviting Marine to the meeting and giving her the opportunity to share her work with more people.
Great surprise for Marine: Marijke and Marlie Gouws, the farmers family who accommodated her in the Karoo and helped her so much with her project, travelled to the Little Karoo to come to the meeting!
The Endangered Wildlife Trust (EWT) and the South African National Biodiversity Institute (SANBI) are launching the 2016 Red List of Mammals of South Africa, Lesotho and Swaziland. This Red List provides an up-to-date assessment of the state of South African mammals, of which 57 (17%) are deemed to be threatened with extinction and 34 (10%) are Near Threatened.
Assessments are carried out through vast networks of scientists, conservationists and other stakeholders pooling their knowledge. Red Lists have become the backbone of global conservation as a unified and standardized tool to measure biodiversity loss and inform policy and conservation planning. The 2016 Red List of Mammals of South Africa, Lesotho and Swaziland was produced by the EWT and SANBI, with collaboration from the universities of Cape Town and Pretoria’s MammalMAP and the IUCN Species Survival Commission (SSC), provincial and national conservation agencies, museums and universities. For more information on these Red Lists, click here.
The Karoo Predator Project took part in several of these assessments for:
- the caracal
- the black-footed cat
- the black-backed jackal (soon to be available)
- the grey rhebok (national (soon to be available) and global)
- the chacma baboon
Have a look at them, they are full of interesting information!
I am really excited to announce the launch of a newly-created interdisciplinary Institute at the University of Cape Town, called iCWild for Institute for Communities and Wildlife in Africa. The aim of the Institute is to understand the “wicked problems” stemming from conservation conflict.
The Institute is working closely with researchers and students, NGOs, government agencies… on different species and systems, from baboons, caracals and sharks in Cape Town to leopards in KZN and jackals in the Karoo.
The Karoo Predator Project is part of the Institute and it’s Storme Viljoen, our little MSc student, who became its manager, based at UCT. Well done Storme, we are proud of you!
If you are interested in wildlife and communities in Africa, and how both interact on the continent, please consider following the Institute’s facebook page (https://www.facebook.com/icwild), Twitter (https://twitter.com/iCWild) and Instagram (https://www.instagram.com/icwild/) accounts. They will be populated with news, pictures, stories from the field and much more very soon.
The South African Wildlife Management Association (SAWMA) held its annual symposium in the Boland mountains of the Western Cape during the week of 10-14 September. This year’s main theme was “Wildlife Management in the Face of Global Change”. Scientists, students, managers and decision makers in the field of wildlife and natural resource management gathered to present their work and discuss the latest research and management findings in (southern) Africa.
Both Justin and Marine presented their work, but Justin talked about monkey management in Cape Town. Unfortunately, Marion could not present her research on Karoo baboons this year. We also missed Storme who is busy writing up her research at the moment. Marine presented her camera trapping work in a talk titled “Community structure, diversity and distribution of semi-desert mammals and ground birds living on farmland and a protected area” and won the second prize for the PhD presentations.

This year, we were lucky to once again have really interesting keynote speakers. It was great to have the chance to meet and discuss with colleagues from all across the country. The Association did an excellent job in organizing the symposium, which was very successful. Prof. Steven Redpath (University of Aberdeen), Dr. Pip Masters (Envisage Environmental Services, Australia) and Dr. Ben Allen (University of Southern Queensland) joined Justin and some students from iCWild for a post-conference field trip.
The Karoo Predator Project would like to thank SAWMA for the great symposium they organize each year and AfriVet and ESAG for the super cool student prizes!
Marine, all happy with the books she received as the runner-up of the PhD presentations.
I am glad to share with you today a new publication in which the Karoo Predator Project took part recently about the phylogeny of African jackals. The research was led by Dr. Anagaw Atickem, Dr. Christian Roos and Dr. Dietmar Zinner from the German Primate Center (DPZ) in Germany. It was published in Zoologica Scripta under the title “Deep divergence among mitochondrial lineages in African jackals“. This study contributes to close the gap in our knowledge about the evolutionary history of canids by investigating the phylogenetic relationship between populations of African jackals Lupulella mesomelas and Lupulella adusta. And yes, as you have noticed, the black-backed jackal won’t be called Canis mesomelas anymore, but Lupulella mesomelas! But the most exciting and interesting point of the paper is that the two mesomelas populations, the one from southern Africa and the one from Eastern Africa, might in fact be two different species. More research is needed to conclude on that last point though.

Recently, molecular analyses revealed that African and Eurasian golden jackals are distinct species. This finding suggests re-investigation of the phylogenetic relationships and taxonomy of other African members of the Canidae. Here, we provide a study on the phylogenetic relationship between populations of African jackals Lupulella mesomelas and L. adusta inferred from 962 bp of the mitochondrial cytochrome b (cytb) gene. As expected from its disjunct distribution, with one population in eastern Africa and the other one in southern Africa, we found two mitochondrial lineages within L. mesomelas, which diverged about 2.5 million years ago (Ma). In contrast, in L. adusta with its more continuous distribution in sub- Saharan Africa, we found only a shallower genetic diversification, with the exception of the West African population, which diverged around 1.4 Ma from the Central and East African populations. Both divergence ages are older than, for example the 1.1–0.9 million years between the grey wolf Canis lupus and the African golden wolf C. lupaster. One taxonomic implication of our findings might be that the two L. mesomelas populations warrant species status. However, genome-wide data with adequate geographical sampling are needed to substantiate our results.
