Authors: Chad Keates, Werner Conradie, Eli Greenbaum, Shelley Edwards Abstract: Psammophylax (Fitzinger 1843) is a widespread yet poorly studied genus of African grass snakes. A genetic phylogeny of six of the seven species was estimated using multiple phylogenetic and distance‐based methods. To support the genetic analyses, we conducted morphological analyses on the body (traditional morphology) and head (geometric morphometrics) separately. Phylogenetic analyses recovered a similar topology to past studies, but with better resolution… Read More
At the beginning of 2018, myself and Luke Kemp joined the Rhodes ZEML (Zoology and Entomology Molecular Lab) herpetological cross-country fieldtrip. The trip saw us adventuring throughout South Africa, in search of frogs and reptiles alike. This first video details our time in Rhodes, a small town just south of Lesotho.
On Tuesday the 12th of June, myself and Dr Shelley Edwards presented a snake demonstration for members of the Kingswood College Environmental Club. The demonstration was well received and after a short introduction, most students took the opportunity to handle the snakes on display. It was a great time spent with some enthusiastic students, and I look forward to my next talk at the school.
On sunday the 19th of November, myself and Luke Kemp hosted a snake awareness ‘walk and talk’ on mountain drive. The aim of the event was to expose the local Grahamstownian’s to the enormous herpetological diversity that the area has to offer. The day started off with a bit of ‘show and tell’ in the Rhodes Zoology and Entomology department parking with Grahamstown’s most venomous snake, the cape cobra (Naja nivea). Following… Read More
Today I received my samples back from their holiday in Amsterdam, and I am happy to announce that all but one sample worked. The samples from today coupled with the samples I received last month amount to 75 successfully sequenced samples to date. These samples, which comprise four genes, make up a large proportion of my sample set and thus represent a massive step forward in the completion of my thesis. But… Read More
So as I am sure you have you gathered, I could not let the little ‘sheep stabbers’ go. Instead of just finishing my honours and leaving the skaapstekers in my rear view mirror, like I did with the painted reed frogs, I decided to continue on studying the snake with the addition of everyone else in the genus. Unlike with my honours, my masters will investigate the entire genus which is ‘currently’ six… Read More
