Outcome of IPS Galante Family Winery Conservation Scholarships

The IPS received outstanding applications this year, and we are delighted to have been able to grant two fantastics applicants funds to pursue their proposed study/training programme.


Ms. Eka Cahyaningrum from Indonesia: $1,500 to supplement missing tuition fee funds to pursue the YALE Tropical Forest Landscape Online Certification. Eka has been working in the past 4 years with the Borneo Nature Foundation as the main Gibbon and Red Langur Researcher in situ and she has been excelling in this position, demonstrating strong leadership and teamwork skills, as well as scientific promise. Eka is currently working to create a new NGO in Indonesia, as well as working as Vice-Chair of the IUCN PSG Section on Small Apes to develop Action Plans for gibbons in Indonesia.

Mr. Rogit Negi from India: $2,500 to pursue an unpaid internship at the Cognitive Ethology Laboratory at the German Primate Center in Göttingen, Germany (Start date October 2021, these funds supplement funds Rogit recently secured from the Inlaks-Ravi Sankaran (RS) internship scholarship 2021-2022, meaning that Rogit will now be able to pursue this internship in Germany). Rogit is a budding primatologist in his home country. This internship will help him cement his skills, especially in statistical analysis of data and molecular techniques for non-invasive samples, such as feces. The focus of his interest and research are to inform management strategies to improve conservation action of primates in India. He has already contributed significantly to an interesting project entitled ‘Socioecology of coconut consumption and predator cognition by Nicobar long-tailed macaques for mitigation of conflict with human/dogs”.

Object Manipulation and Tool Use in Nicobar Long-Tailed Macaques (Macaca fascicularis umbrosus)

Jayashree Mazumder & Stefano S. K. Kaburu

Object manipulation and tool use by nonhuman primates have received considerable attention from primatologists and anthropologists, because of their broad implications for understanding the evolution of tool use in humans. To date, however, most of the studies on this topic have focused on apes, given their close evolutionary relationship with humans. In contrast, fewer studies on tool use and object manipulation have been conducted on more


Comparing Methods for Assessing Chimpanzee (Pan troglodytes schweinfurthii) Party Size: Observations, Camera Traps, and Bed Counts from a Savanna-Woodland Mosaic in the Issa Valley, Tanzania

Daphne N. Vink, Fiona A. Stewart & Alex K. Piel

Studying animal grouping behavior is important for understanding the causes and consequences of sociality and has implications for conservation. Chimpanzee (Pan troglodytes) party size is often assessed by counting individuals or extracted indirectly from camera trap footage or the number of nests. Little is known, however, about consistency across more
