CURRENT LAB MEMBERS
Rob Pringle, Professor
I have always been fascinated by the ways in which species interactions “cascade” through food webs and other ecological networks, often with surprising outcomes. Research in my lab focuses on three main problems. The first is trying to understand the ways in which large mammalian herbivores directly and indirectly shape the ecosystems they inhabit: how do they affect plants and other animals, and what can this tell us about the likely impacts of past and future extinctions? A related focus is on how top predators structure communities by altering the abundance and behavior of their prey. Finally, I am interested in the spatial organization of these ecosystems–specifically, how regular patterns created by ecosystem engineers like termites influence the behavior of individuals, populations, and ecosystems.

Maia Raymundo, Postdoc
I am a broadly trained ecologist and conservation biologist. My research interests lie at the intersection of conservation and the application of fundamental ecological theory to improve conservation and restoration outcomes. Because conservation issues are innately complex and require the engagement of multiple disciplines, I have previously drawn on a synthesis of approaches integrating empirical and applied ecology, ecological theory, phylogenetics, and ethnobiology. The thrust of my research that I will be undertaking in the Pringle Lab will focus on combining molecular techniques and community ecology to inform restoration strategies for the Marianas fruit bat (Pteropus mariannus) and its habitats on the island of Guam.

Lotanna Micah Nneji, Postdoc
I am interested in understanding the diversity, ecology, population genetics and distribution patterns of animals such as invertebrates (butterflies and moths), freshwater fishes, amphibians, reptiles, birds and mammals. My research incorporates ecological and molecular data to investigate the evolutionary ecology of animals. During my PhD, I studied the diversity of herpetofauna in Gashaka Gumti National Park (Nigeria) using a short diagnostic gene fragment (DNA barcode) for rapid species identification and ecological studies. In the Pringle lab, I will conduct the first DNA metabarcoding analyses of the diet composition and niche relationships of herbivorous birds – Ostrich, guineafowl, spurfowl, and bustard – at Mpala Research Centre in Kenya.

Erin Phillips, Graduate Student
Broadly, I am interested in how predator-prey and predator-predator interactions act to shape ecosystem structure, function and biodiversity, and in the implications of this for conservation action and policy. In my PhD, I am studying the impact of apex carnivore reintroduction on natural populations, and particularly on understudied mesocarnivores, in Gorongosa National Park. I graduated from the University of St Andrews in 2018 with BSc in Zoology, where I studied the impacts of prey group shape on detection by birds, and later the effect of predator avoidance on longevity in reptiles and amphibians. From 2018-20, I studied at Emory University on a Bobby Jones Scholarship, where I approached animal behavior from a new angle, researching canine cognitive neuroscience via awake fMRI. [CV]
Finote Gijsman, Graduate Student
I am broadly interested in plant-insect interactions and the roles they play in maintaining ecosystem biodiversity. For my undergraduate thesis, I investigated the impacts of a non-native, seed-eating weevil on the reproductive success of Cirsium pitcheri, a threatened keystone species endemic to the Great Lakes region of the United States. After graduating from Northwestern University in 2019, I spent a year working at the Smithsonian Tropical Research Institute in Panama and Max Planck Institute of Chemical Ecology in Germany gaining experience in the fields of chemical ecology and plant-insect interactions. In the Pringle Lab, I am interested in investigating the role that chemistry plays in mediating plant-insect food webs and interactions. [CV]
Joel Abraham, Graduate Student
Disturbances are of paramount importance in structuring ecological communities. I study how these disturbances — particularly herbivory, fire, and flooding — interact with one another and the implications this has for ecosystem structure and function. I use Gorongosa National Park as a model system in which to investigate disturbance interactions. Previously as a member of the Staver Lab at Yale University I studied the behavioral responses of savanna herbivores to drought in Kruger National Park. I graduated from Yale in 2018 with a B.S. in Ecology & Evolutionary Biology as well as Environmental Studies; I remained there for a year as a lab technician before joining the Pringle Lab here at Princeton. [CV]
Harrison Watson, Graduate Student
The carbon sink/source potential of tropical savanna ecosystems are largely unclear, despite their importance to global carbon cycling and sequestration. In particular, I’m interested in how disturbance from fire and herbivory influence carbon sequestration in these systems. My research combines theoretical modeling techniques with field work in Kenya and South Africa to understand the role of disturbance in clarifying the carbon storage potential of tropical savannas. I graduated from Jackson State University in 2019 with a BSc in Marine Biology where I studied mitochondrial genomics using species of crustaceans native to the northern Gulf of Mexico.
Ciara Nutter, Lab Manager
I am interested in how the structure of ecological interaction networks affects ecosystem functioning and stability. More specifically, I am captivated by how diets and food webs vary across scales, how they are altered in response to anthropogenic change, and what the ecosystem-level consequences of these alterations are. I graduated from Princeton University in 2018 with a B.A. in Ecology & Evolutionary Biology. After graduating, I joined Mpala Research Centre, Kenya as a Princeton in Africa Fellow assisting interdisciplinary projects at the intersection of science, education and conservation before returning to Princeton.
