Meet The Team

Rhianna Drummond-Clarke

Researcher, Chimpanzee positional behaviour

January - November 2020

My fascination with apes started whilst studying for a masters in Palaeobiology at University College London (UK), where I studied ape dental morphology as a means to place fossil apes into ape taxonomy. After graduating in 2013, I wanted to explore the relationship between form and function further, leading me to seek work opportunities with living apes. I have since worked in chimpanzee conservation and research in Guinea and The Ivory Coast, and in 2020 undertook my own independent project at Issa, studying chimpanzee positional behaviour and habitat use, also investigating how/if their habitat use and behaviour changes in response to seasonal fires. I am currently a PhD student at the University of Kent working under Tracy Kivell.

Christian Howells

Research and Project Manager

December 2019 - September 2020

I have an MSc in Primate Conservation from Oxford Brookes University. Carrying out my thesis research in Uganda’s Budongo Forest Reserve, I focused on chimpanzee stress hormone responses to fragmented, anthropogenic landscapes. Before completing my MSc, I worked with the Borneo Nature Foundation contributing to biodiversity surveys and long-term orangutan, gibbon and red-langur behaviour projects. From 2016 onward I have worked as the Research Officer for a zoological park and as a Lecturer in Higher education, specialising in wildlife conservation. My particular interests revolve around the anthropogenic impacts humans can present to wild primates and how humans may alter zoo-housed primate behaviour, both impacting species conservation status and welfare. I began a PhD in Fall 2020 at the University of Lisbon.

Caroline Fryns

Chimpanzee Project Coordinator

May 2019 - July 2020

I received my Master’s degree in Biology from the University of Strasbourg (France) in 2016, focusing on lizard sociality for her master’s thesis. Since graduating I have worked at the Tuanan Orangutan Research Project (TORP) in Borneo, Indonesia. My interests lie in primatology and social behaviour. I oversaw the chimpanzee project at Issa, making this the second great ape species on which I have worked. I have recently collated observations of chimpanzees and cattle, submitted for publication in December 2020 and am currently a PhD student at the Unviersity of Neuchatel.

Charlotte Bright

Research and Project Manager

January 2019 - November 2019

I received my Master’s degree in Biology from the University of Sheffield in 2016, focussing on behaviour and genetics in zebrafish. My interests strongly lie within the behavioural ecology of social species as well as related human-wildlife conflict issues. Since graduating, I have assisted on various research projects across Africa including spotted hyena feeding ecology in Zimbabwe, large carnivore behavioural ecology in Kasungu National Park, Malawi and chacma baboon social networking in Tsaobis, Namibia. With Bethan Mason, I over-saw research at GMERC until November 2019 when I was offered a PhD position with Simone Pika in the Comparative BioCognition (CBC) Group, Institute of Cognitive Science at the University of Osnabrück in Germany.

Christopher Lile

Researcher

Red-tailed monkey feeding ecology

August 2018 - February 2019

I led an intensive study of red-tailed monkey feeding ecology, collecting botanical specimens to improve our understanding of their dietary diversity and especially overlap with sympatric chimpanzees and baboons. Whilst at Issa, I published two articles: the first on red-tailed monkey preying on birds, which you can read in Primates, here, and later I was invited to describe my research work in an article for the Zoological Association of America. Our work on feeding ecology is currently in prep!

Anita Erikson

Researcher, University of Oslo (Norway)

Chimpanzee diet

August 2018 - February 2019

Anita always had a strong interest for nature and wildlife, resulting in many adventures into nature in all corners of the world. She achieved a bachelor’s degree in biology: a combination of theoretical biology at the University of Oslo, Norway, and wildlife management and conservation at Stellenbosch University, Western Cape South Africa, and completed a master’s degree, on foraging ecology in gelada monkeys, Guassa Ethiopia, in September 2017. Her passion for primate conservation continues and at Issa, she worked on foraging strategies in yellow baboons and worked in paternship with Camille Giuliano (LJMU). Anita wishes to pursue a career in African wildlife management and conservation.

Lillian Fornof

Researcher, Swarthmore College (USA)

Landscapes of fear in red-tailed monkeys

July - August 2018

I conducted research for my undergraduate honors thesis at Issa Valley. My thesis examined the 'landscape of fear' of red-tailed monkeys (Cercopithecus ascanius), which models the spatial distribution of safe and risky regions from predation in a prey's home range. Working with the GMERC team, I was able to collect data on multiple antipredator behaviors to create distinct LOF models for each behavior, a feat not yet done in LOF research. Antipredator behaviors not only created spatially unique LOFs, but were also predicted differently by other environmental and demographic data. These findings challenge whether only one of multiple antipredator behaviors can accurately portray a landscape of the predation risk prey face. I presented preliminary results at the 2019 AAPA meetings, here. Currently I am a PhD student at Harvard University, and preparing these results for publication.

Rebecca Ingram

Researcher, Landscape chimpanzee surveys

May - October 2018

Becki led surveys of chimpanzees and other biodiversity across the northern Masito-Ugalla Ecosystem (MUE). She developed interests in tropical ecology, and particularly primate behavioural ecology and conservation throughout her life. In 2013 she received her bachelor’s degree in Geography (University of Birmingham, UK), completing her thesis on human-wildlife conflict (with a focus on the Buton macaque) on Buton island in Indonesia. Following this, she took up a year-long position with the Gunung Palung Orangutan Conservation Project, assisting with research of wild Bornean orangutans in West Kalimantan, Indonesia. In 2016, she completed a masters of research in Primate Biology, Behaviour and Conservation (Roehampton University, UK), spending three months in Nigeria studying olive baboons for her thesis, and returning to Gashaka Gumti National Park in 2018 for an expedition to explore as of yet unknown areas around the Gangirwal escarpment. Becki spent almost two years working for Natural England, advising the English government on issues relating to wildlife conservation and land use, before taking up the role to lead wildlife surveys in Tanzania.

Laura Jessup

PhD student, Purdue University (USA)

Soundcapes

April - June 2018

Laura is a PhD student in the Department of Forestry and Natural Resources at Purdue University (USA). Prior to her time at Purdue, Laura completed a bachelor’s degree in music from Alma College, a master’s degree in biology from Eastern Kentucky University, and worked for the US Forest Service as a natural resources trainee. Now, Laura is studying how the sounds of animals, streams, and weather vary with vegetation phenology and structure. She plans to develop methods for remotely sensing habitat type and biodiversity using acoustics.

Bethan Mason

Msc student; Research and Project Manager, Liverpool John Moores University

March 2018; September 2018 - July 2019

As a wildlife conservation student my project combined primate parasitology with human disturbance research. I collected faecal samples from multiple yellow baboon troops, located both around the GMERC research centre and near the closest town, Uvinza. These faecal samples were later analysed for parasite presence, providing an insight into the gastrointestinal parasite load of all the sampled troops. Alongside the faecal collections, transects were used to determine the level of human disturbance to the environment at each troops location. I aimed to show an indication of the potential influence of human disturbance on primate parasite load. Results have been submitted for publication and are expected out in early 2021.

May - October 2018

The main area of focus for my research surrounds the following proposals;

1) To classify tree species in the miombo woodland using multispectral data from a UAV

2) To compare tree species classification using multispectral UAV and satellite data

3) To use multispectral UAV data to identify fig trees in miombo woodland

Camille Giuliano

PhD student, Liverpool John Moores University (UK)

Chimpanzee behavioural ecology

April 2018- May 2019

My PhD research investigates how Issa's chimpanzees adapt to the dry, open, and highly seasonal environment of the Issa valley, western Tanzania. More precisely, my project examines chimpanzee responses to periods of resource scarcity by examining season-specific changes in diet, physiology, sociality and ranging. Two primary objectives drive this project (1) redress profound and longstanding biases in our knowledge of chimpanzee species by studying a population living in a marginal environment (2) infer early hominin adaptations to a similar environment and provide testable hypotheses to paleoanthropologists. The first chapter from the work is under revision and due out in early 2021.

Researcher, Liverpool John Moores University

Chimpanzee Distribution, Mahale Mountains National Park

February 2018- February 2019

With Adrienne Chitayat, Matthew led a survey of chimpanzees and other biodiversity in Mahale Mountains National Park. He developed interests in tropical ecology and the conservation of African wildlife, nurtured during part of his childhood spent in southern Tanzania. In 2015 he received his bachelor’s degree in Zoology (Trinity College, Dublin), swiftly taking up a position with the Max Planck Institute studying population dynamics of central African chimpanzees and western lowland gorillas in Loango National Park, Gabon. He then spent a further year in Gabon, as a team leader for the forest elephant movement and behavioural ecology project with Duke University in Ivindo National Park, following which he returned to Tanzania.

Daphne Vink

Msc student, University of Amsterdam (Netherlands)

Chimpanzee party size dynamics

January - May 2018

Daphne was a master student from the University of Amsterdam, interested in the behavioural ecology of primates. In her previous research projects she examined the functional diversity of primates across the world, and the link between colour vision in primates and the colour of palm fruits (available here). At Issa, she studied what environmental and methodological (camera traps, nest parties, and direct observations) factors influence chimpanzee party count estimates. This work was published as part of a Special Issue on Savanna Chimpanzees (with an Issa chimpanzee on the cover!) in the International J of Primatology, which you can read here.

Seth Phillips

Researcher, University of California, Santa Cruz

Chimpanzee Termite Fishing Ecology

December 2017 - May 2018

She is currently a PhD candidate at the University of Wisconsin, Madison.

Anne-Sophie Crunchant

PhD student, Liverpool John Moores University (UK)

Chimpanzee Bioacoustics

May-July 2017; March-December 2018; July-October 2019

My research interests focused on animal communication and primate conservation. My PhD investigated acoustic communication and how to use passive acoustic monitoring as a non-invasive tool for ape conservation. Specifically, I am interested in developing and testing a new method to acoustically estimate chimpanzee density and compare results with more traditional methods. Another part of my project was to investigate the potential effect of silent chimpanzee on their distribution estimation when using passive acoustic vs camera trap monitoring (see here). I was interested in detecting and localising chimpanzees at their nesting site to further investigate the possibility of predicting party size from bioacoustics data. I completed my viva at LJMU in December 2020 and left immediately for Kokolopro, DRC where I will be working on bonobo nutrition.

Sonja Greil

Georgia came to Issa the summer before starting her undergraduate degree in Psychology at the University of Oxford. This was her first experience of wild chimpanzeee field research, although previously she had worked with chimpanzees during an internship at the Primate Research Institute of Kyoto University. Whilst at Issa, Georgia focussed on tracking chimpanzees as part of the habituation process, and investigating their habitat use by looking at long term data. She also participated in other aspects of research at Issa, such as following habituated yellow baboons and walking lines transects to monitor large mammal densities. Georgia began Bachelor’s work at Oxford University in Fall 2017 and was graduated in 2020.

Alexandra Robison

Msc student, Liverpool John Moores University (UK)

Yellow baboon leadership

April-June 2017

For Alex’s masters dissertation in primate behaviour and conservation at LJMU, she looked into leadership behaviour and progression positions in Issa's yellow baboons, particularly the leadership style of the camp troop of baboons, the pre departure body language of members of the troop and the influences on departure time. As well as this, Alex  looked into what may affect the progression positions of this troop of baboons. Alex is hoping to continue studying primates and begin a PhD in the near future.

Kelly van Leeuwen

PhD student, Bournemouth University (UK)

Agent-based modelling and chimpanzee behavioural ecology

April-June 2017

Kelly's PhD research was a combination of fieldwork and agent-based modelling. She used individual-based and referential modelling to explore hominid (i.e. chimpanzee, Ardipithecus ramidus and Australopithecus anamensis/ afarensis) landscape use along an environmental gradient from forests to savannahs to determine their adaptability to change. The first paper from her PhD, published in IJP in 2020 as part of a Special Issue on "Savanna Chimpanzees", was an assessment of 'savanna' landscapes, and can be found here. She received her PhD from Bournemouth Univ in 2019.
