The WWF’s emblematic animal, the Giant Panda has becomethe symbol of “Endangered” animals.
There are now only about 1,600 of them left, spread over 64 nature reserves in central China, in the mountains of Sichuan, Shaanxi and Gansu. And there are very few of them in zoos.
The symbol of endangered animal species
essentially vegetarian, eating practically nothing but bamboo
In morphological terms, the panda is a bear but it is essentially vegetarian, eating practically nothing but bamboo, from which its ursine digestive tract enables it to extract only a part of the nutritional value. It is therefore obliged to eat almost all the time and it is unable to store enough reserves of fat to allow it to hibernate during the winter.
Its mountain habitat is very rainy and rather cold : the Giant Pandas of Pairi Daiza, which have thick fur, therefore appreciate our Belgian weather.
Endowed with powerful claws, pandas easily climb trees. They have a sixth finger which is a bony growth on their wrist, opposite the other fingers, which enables them to hold bamboo stems. In view of their very low reproduction rate and the threats to their habitat, the species is classified as “Vulnerable”.
Jella Wauters leads the research project “Metabolomics in the Giant Panda: unraveling the reproductive biology” for the Pairi Daiza Foundation at the Faculty of Veterinary Medicine of Ghent University. This study aims to develop a test that will allow scientists worldwide to predict the female panda’s heat period (a few weeks before it begins) based on hormonal markers present in the animal’s urine.
The fertility period of a female Giant Panda occurs only once a year and lasts only one to three days. If fertilization occurs during this short period, the rest of the pregnancy remains a huge mystery. The precise duration of the pregnancy, miscarriages, and/or reasons for absorption of the fetus by the reproductive system in the female Giant Panda are still unknown to date.
The hormonal markers, central to Jella Wauters’ work, can also indicate the precise moment of ovulation and track the progress of one of the most mysterious pregnancies in the animal kingdom, ultimately significantly increasing the chances of reproduction, not only in zoos and breeding centers in China but also in the wild.
