Binturong data on field :

Status: Draft in progress for a future publication in a scientific journal

Since the beginning, ABConservation has commited to raise scientifique knowledges on the Bearcat. Indeed, this species is not only little known by the general public, but also few studied by scientists, even so more publications have been written since 2015. One of the first study started by the organisation consisted of the study of the geographic range of the Bearcat. For the project, the whole scientific publications quoting the observation of bearcats in the wild have been studied and numerous scientists have been contacted. Thus, thanks to the summarize of 51 papers confirming the presence of the binturong in Asia and the participation of scientists, that agreed to share their data with us, we were able to realise the first interactive map of the bearcat’s geographic distribution, available here.

The informations on the locations of the binturong are classified by dates of observation of the individuals. The more recent studies are quite homogeneously spread over the whole geographic theoretical range of the binturong (Widmann et al., 2008, available map on the website of the IUCN here) and confirm the scarcity of bearcats in Vietnam, as only two studies confirm its presence in this country. Informations are also rare concerning Sumatra and Java islands, that lead us to wonder about the status of the bearcat in those areas. On the opposite, the presence of the bearcat in West Myanmar (Zaw et al., 2008) represent an extension of its geographic range comparing to the map of the IUCN. It could be thus interesting to investigate the repartition of the bearcat in Myanmar.

A scientific paper is currently being written and we hope that the future field work will help to complete this map and allow precise updates of the map of the bearcat’s geographic range in South-East Asia.

Study on binturong subspecies :

Status : Collect of data ongoing 

According to Cosson et al. (2007), 9 subspecies of binturong might exist. Yet those results come essentially from captive data and still need to be confirmed, even if one of the subspecies is now well known and described, Arctictis binturong whitei from Palawan. Furthermore, strong differences in the size, the weight and the fur of the binturongs are often observed in zoological parks. Thus, this studies aims to measure the disparity of captive binturong morphology and to link it to the subspecies in the Bearcat, Arctictis binturong. The data are collected in the institutions across the world thanks to a simple survey. Data are still being collected, if you want to participate in our study, please send see below “Useful link and files”.

Measure of the HPA axis and the behavior of a captive species

of Viverridae, the bearcat, Arctictis binturong 

Status: Draft in progress for a future publication in a scientific journal

 

The binturong, Arctictis binturong, is a threatened species living in the forest of South-East Asia. According to its decline, the raising programs in zoological parks play an important role, but they have to face some issues with the reproduction of this species. This thesis aimed first to make a complete bibliography of the binturong, and then to set up a method to evaluate the stress of captive individuals. From this perspective, behavioral observations and assays of fecal cortisol metabolites (FCM) have been realized on 10 individuals from 6 French zoological parks. By the comparison of 4 extraction protocols, it appears that the FCM dosage on wet samples and with the use of a vortex is the most efficient method on binturongs. The next stage of the study with the assay of FCM from an individual towards its transfer from an institution to another allowed the biological validation of FCM as stress indicators in binturongs. Finally, the behavioral observations revealed that the majority of the group showed frustration by expressing anticipatory behavior. Furthermore, the individuals with strongest anticipatory behaviors had low levels of FCM that leads us to suppose that an important chronic stress could imply a severe inhibition of cortisol excretion in binturongs.
