Snapshot Serengeti, high-frequency annotated camera trap images of 40 mammalian species in an African savanna
This work deployed 225 camera traps across Serengeti National Park, Tanzania, to evaluate spatial and temporal inter-species dynamics and classified the images via the citizen-science website www.snapshotsereNGeti.org, yielding a final classification for each image and a measure of agreement among individual answers.

Effects of trophy hunting on lion and leopard populations in Tanzania.
Lion population trends in protected areas where lion abundance has been directly measured and data on the frequency of lion attacks on humans in high-conflict agricultural areas are summarized and quantitative analyses suggest that annual hunting quotas should be limited. Expand
Keeping the herds healthy and alert: implications of predator control for infectious disease
This work develops models for microparasitic and macroparAsitic infection that specify the conditions where predator removal will increase the incidence of parasitic infection, reduce the number of healthy individuals in the prey population and decrease the overall size of the predator population.

Abstract In three adjacent troops of olive baboons (Papio anubis), all males emigrated from their natal troop. There is evidence that the costs of inbreeding depression may exceed those ofExpand
Transmission Dynamics and Prospects for the Elimination of Canine Rabies
It is found that the basic reproductive number for rabies, R0, is very low in the study area in rural Africa and throughout its historic global range, which provides strong support for the feasibility of controlling endemic canine rabies by vaccination by vaccination. Expand
Planning for success: Serengeti lions seek prey accessibility rather than abundance
Summary 1. We used long-term radio-telemetry data to investigate how Serengeti lions ( Panthera leo ) distribute themselves with respect to hunting opportunities. Specifically, we investigate whetherExpand
A molecular genetic analysis of kinship and cooperation in African lions
A new application of DNA fingerprinting is described that unequivocally demonstrates the kinship structure of lion 'prides': female companions are always closely related, male companions are either closely related or unrelated, and mating partners are usually unrelated. Expand
Why Lions Form Groups: Food is Not Enough
It is found that mothers keep their cubs in a creche and form highly stable maternity groups that are effective in defending the cubs against infanticidal males, and larger groups successfully repel smaller ones in territorial disputes. Expand
Automatically identifying, counting, and describing wild animals in camera-trap images with deep learning
The ability to automatically, accurately, and inexpensively collect such data, which could help catalyze the transformation of many fields of ecology, wildlife biology, zoology, conservation biology, and animal behavior into “big data” sciences is investigated. Expand
The Evolution of Sex-Biased Dispersal in Lions
Most female lions remain in their natal pride for their entire lives, but about a third emigrate before they reach four yrs of age. Most emigrating females leave either when they are evicted by anExpand
