A rethink about giraffes

If you thought that all giraffes were created equal, think again. Yes, based on their looks they all seem pretty much the same, but their genes tell a totally different story. The ones you’ll see in the Kruger National Park or elsewhere in South Africa are genetically very different from the ones in Ethiopia and…

When it comes to the breeding success of common white terns, “artificial” seems to be better than “natural”. This is the results from a study conducted by researchers from the University of KwaZulu-Natal and colleagues in the Seychelles.

City living = stress for African lesser bushbabies

Mostly a loner, the African lesser bushbaby feeds on insects, supplementing its diet with sugar-rich gum of the acacia tree, as well as fruits. When urbanised, the availability of sugar-rich food sources, such as yogurt, catfood and bread, drives the lesser bushbaby to abandon its solitary lifestyle. As a result, the fight for food at…

Plastics are the death of sea turtles – @Scibraai Monday Menu

Pieces of plastic floating in our oceans are creating an often life-threatening problem for our sea life. Of the 40 loggerhead turtles that died after being stranded along the southern Cape coastline in one month alone, 24 (60%) had ingested debris such as plastics, fibres and pieces of packaging material. In an article in Marine…

What is in the water that great white sharks swim in? #Scibraai Monday Menu

Skin samples of great white sharks contain worrying levels of environmental and biological contaminants. This is among the findings of a recent study in the journal Expert Opinion on Environmental Biology. Skin biopsies were taken from 15 great white sharks near Dyer Island off the Overberg coastline. The Italian and South African researchers involved ascribe…
