Integrating Camera Trap, Visual, and Dung Survey Data
Accurate estimations of animal populations are necessary for management, conservation, and policy decisions. However, methods for surveying animal communities disproportionately represent specific groups or guilds. We present a modelling framework that both compares and integrates field-collected dung, visual, and camera trap data to more robustly estimate animal populations in data-scarce environments.
How to Estimate the Gut Passage Time of Wild Forest Elephants
Knowledge of gut passage time is essential for understanding vertebrate-mediated ecological processes like seed dispersal. We apply and compare three novel methods -- modified seeds, colored plastic pellets, and Thermocron temperature logging iButtons -- to estimate the gut passage time in wild forest elephants for the first time.
Exploring the Unacknowledged Dimension of Habitat Variability
In Press, Ecological Monographs (2019)
Highly-variable, synchronous seed production in forests provides a pulsed resource that both supports and destabilizes food webs. We provide a model that combines knowledge of consumer life histories with the emergent space-time covariance structure of fruit and seed production to assess the ability of habitats to provide for important consumer groups.
Long Term Effects of Low-Intensity Logging on Seed Dispersal
Annals of Botany, Plants (2018)
Low intensity logging has been proposed as a sustainable solution for timber harvesting in the tropics, but long-term alterations in seed dispersal may have big effects on community composition and ecosystem function.
Forest Elephant Extirpation Will Transform African Forests
Conservation Biology (2018)
Large herbivores like forest elephants might be the only thing keeping Afrotropical forests from turning into the Neotropics, and they're headed for extinction.
The Joint Responses of Growth and Survival to Adversity
American Journal of Primatology (2015)
We've long suspected that later-born infants fare better than first-born siblings, but 34 years of macaque survival data suggests otherwise.
