Wildlife diseases management: a case study from Periyar Tiger Reserve, Kerala, India

Humboldtia bourdillonii is an Endangered tree legume; considered endemic to its type locality in the Periyar Tiger Reserve in Idukki District of Kerala State. A new population of this highly threatened endemic species is located in the Vagamon Hills of Kottayam District which is about 70km away from its original locality. The newly located population is drastically affected by the severe floods and landslides that occurred in Kerala state during August 2018. Urgent conservation measures are needed to protect the population from further loss.

Objectives: The present study was undertaken to screen pancreatic lipase inhibitory activity of crude extracts of actinomycetes species isolated from the soil sediments of Periyar Tiger Reserve, Kerala. The identified lipase inhibitory activity was partially purified, and the selected isolate was identified by 16S rRNA sequencing. Methods: The preliminary screening for the extracellular lipase inhibitory activities of actinomycetes isolates was performed by inoculating the culture to the test tubes containing inoculation media in submerged condition. The lipase inhibitory activities were again evaluated based on secondary screening on the production media and the strain which produced consistent highest lipase inhibitory activity was selected for further studies. The crude extract from the selected strain was subjected to solvent extraction and partially purified by plain silica gel column (mesh size 100–200 μm; column 300 mm×18 mm) and eluted with different solvents in the increasing order of polarity and all the solvent fractions were checked for lipase inhibitory activity. Results: Based on the secondary screening on the production of media, DDE6 strain showed highest lipase inhibitory activity (96.2%) and was selected for further studies. The dichloromethane extract showed the highest lipase inhibitory activity (96.38%) when compared to other solvents. The partial 16S rRNA sequence analysis of DDE6 isolate confirmed the strain as Curtobacterium oceanosedimentum. Conclusion: Many research publications have reported the isolation of Curtobacterium species and its type strains. However, this is the first time to report its potential to produce lipase inhibitor metabolite under submerged fermentation conditions. Further, studies are needed to be conducted to characterize the active principle of lipase inhibition as well as to elucidate the structure of the extracted compound.

Abstract This case study explores the reintroduction of tigers to Sariska Tiger Reserve in Rajasthan, India, highlighting how the (re)negotiation between people and tigers is a struggle rooted in place and territory, with boundaries co-constructed by human and nonhuman actors. While the reintroduction came only three years after the official admission of complete species loss, tigers as a dominant force on the landscape were absent for more than a decade in some places. Accordingly, the people of Sariska see the reintroduced tigers as foreigners without place-knowledge and as disturbers of the interspecies boundaries created by the interactions of Sariska’s original tigers and many generations of local people. This study speaks to conservation sciences and animal geography to contribute to the scientific knowledge of the human dimensions of rewilding, still a nascent area of restoration ecology specifically in the case of apex predators in the global south.
