How Studying Feces May Help Us Boost White Rhino Populations

Researchers at North Carolina State University have identified significant differences in the gut microbiome of female southern white rhinos who are reproducing successfully in captivity, as compared to females who have not reproduced successfully in captivity. The work raises questions about the role that a particular genus of gut microbes may be playing in limiting captive breeding of this rhinoceros species.

 
To that end, the researchers collected multiple fecal samples from eight female southern white rhinoceroses over a six-month period. The study population consisted of two juveniles; two "subadults" who are no longer nursing but are not yet of reproductive age; two adults who have reproduced successfully; and two adults who have not reproduced successfully.
 
The researchers extracted and sequenced DNA from the fecal samples, which allowed them to identify the diversity and abundance of bacteria in the gut of the study animals.
