This is a small excerpt of a series of blogs that I have written about some of my work in southern Africa. This one is specifically about the Northern Cape of South Africa.

When I first started working in Southern Africa a few years ago, my original intention was to gather as many data for the dispholidine systematics project as was reasonably possible. However, this quickly evolved into a collaborative effort between multiple institutions and spanning various phylogenetic lineages that hadn't previously been of interest. Since then, I've been able to spend many weeks throughout Southern Africa, in particular South Africa and Swaziland. This blog segment focuses of some of the photographic impressions that I collected during my time in the Northern Cape of South Africa. It is the largest (just a tad smaller than Montana) and least populated province (with barely a few more people than Rhode Island) in South Africa. The Northern Cape borders Namibia and Botswana to the north, and contains numerous famous national parks, such as the Kalahari Gemsbok National Park. Even though many people prefer the lush forests of the eastern provinces or the wine routes of the Western Cape, I have developed a soft spot for the diversity and natural beauty of the Northern Cape. Hopefully the images shown in this blog will give you an adequate insight into this fascinating place.

Large parts of the Northern Cape are covered by the Karoo--a semi-desert region that has a diverse geological history, but is a rough terrain for people to colonize. This picture was taken near the provincial border between the Northern Cape and the Free State.

The Orange River, named after the Dutch Prince of Orange, is a provincial and international border, and biogeographic landmark.

This image was taken near Colesberg, in the eastern part of the Northern Cape. This is an area that saw a lot of fighting during the Anglo-Boer War of the late 19th century.

If we're just going by names, then Pofadder (translated: Puff adder) has got to be my favorite town. This part of South Africa is known as Bushmansland, and due to its infertile soil and saline groundwater is thought to be some of the most inhospitable area in the country. One day, I will have enough time to catch a puff adder in Poffadder.

Sociable weavers (Philetairus socius) are passerid birds that are particularly common in the Northern Cape. They are highly social, and form massive community nests, which can contain over a hundred pairs of birds, consisting of multiple generations. These nests are popular feeding spots for cape cobras (Naja nivea), who can gorge themselves to their heart's desire. This picture was taken near Upington, a town on the northern banks of the Orange River.

The Kalahari Desert is actually a semi-desert, and as such offers a much greater diversity of flora and fauna than a true desert does. Combined with the surrounding basin, it covers 970,000 square miles of area.

Coral cobras (Aspidelaps lubricus) is one of the taxa that we have had our phylogenetic eye on. These small elapids are full of character, and their taxonomy really needs to be brought out of the dark ages. We came across several specimens along the western coast of South Africa, an area called Namaqualand.

This grumpy little bushveld rain frog (Breviceps adspersus) was found south of Mokala National Park, in the eastern part of the Northern Cape. It is a direct developing species that lives underground. When agitated, they inflate themselves in order to avoid removal from the burrow. This one looks slightly ticked...

An angulate tortoise (Chersina angulata) from near Matjeskloof, north of Williston.

Giant ground geckos (Chondrodactylus angulifer) are very common in Namaqualand. This specimen is from Steinkopf.

A juvenile of the same species.

Another very common gecko species is Bibron's thick-toed gecko (Chondrodactylus bibronii).

A gorgeous house snake (Boaedon capensis) from the fringes of the Kalahari desert. The diversity of house snakes in Southern Africa is incredible!

http://calphotos.berkeley.edu/imgs/512x768/0000_0000/0211/1176.jpeg
Gemsbok (Oryx gazella) are some of my favorite antelopes. Their mask-like facial patterns are absolutely stunning!

Another example of sociable weaver (Philetairus socius) nests. These impressive structures can bring down trees.

A terrible picture of a very cool species of owl, the southern white-faced owl (Ptilopsis granti). I took this picture at a farm near Kimberley.

Not something that I expected to come across in the Kalahari desert: Schinz's beaked blind snake (Rhinotyphlops schinzi). This species was named after Dr. Hans Schinz, who collected the first specimens of this taxon.

http://calphotos.berkeley.edu/imgs/512x768/0000_0000/0911/1832.jpeg
A leopard tortoise (Stigmochelys pardalis) from north of Upington. These tortoises are quite common, and I've come across them in many parts of South Africa.

http://calphotos.berkeley.edu/imgs/512x768/0000_0000/0911/2089.jpeg
Another cool colubrid that I've been able to generate a bit of molecular data on: the Namib tiger snake (Telescopus beetzi). This specimen is from Port Nolloth on the western coast of South Africa.

http://calphotos.berkeley.edu/imgs/512x768/0000_0000/0211/1155.jpeg
Bicolored quill-snouted snkaes (Xenocalamus bicolor) are not commonly encountered, and the first time I cam across one I spent several minutes to ascertain my identification of this species. Mind you, stilleto snakes of the genus Atractaspis look somewhat similar, especially at nighttime, and I'm trying hard not to add my name to the list of people who have been bitten by them.

An African clawed frog (Xenopus laevis) -- a model organism in a whole array of biological disciplines. I must admit that I truly despise these things, because they are a pain to catch, worse to hold on to, and impossible to get a decent photograph of. One of the few herps that I may intentionally ignore in the field...

Very nice series of photos.

On the leopard tortoise, is that a babcocki? Though, I just did some looking around and it appears that the babcocki are no longer considered distinct from the paradalis, so I suppose that it a conversation unto itself. Taxonomy aside, did you happen to encounter any non-pyramided wild leopards?

wonderful pictures with some really cool animals i've never seen. thoes weaver nests gross me out~they look like super-sized tent worm nests that get in the trees around here.

Night,

As always your photography is stunning! Must be one hell of an experience to travel there. I'm assuming that you're a professional herpetologist after seeing multiple posts. Forgive me if I'm prying, but what do you do?

The house snake looks like the ones we call Namibian house snakes in the hobby

I've seen wild leopard tortoises both with and without pyramiding. That said, its always comparatively subtle when it occurs in wild specimens. And yes--as with most species, the subspecies of Stigmochelys pardalis have been rejected, including S. p. babcocki.

Night,

No worries at all! Yes, I'm a biologist specializing in the phylogenetic systematics of snakes, especially African snakes. I also teach a variety of college courses in biology and anatomy & physiology.

House snakes are a pet project of mine (excuse the pun :rolleyes:), even though I don't currently keep any myself. I've sampled many of them all over southern Africa, and the initial results of the molecular work suggest that there is a lot more going on than we think. While that project is not currently very high priority, I think we can expect that whole group to be completely taxonomically revised at some point in the near future.
