Seroprevalence and risk factors associated with brucellosis in humans and livestock in Nyagatare district of Rwanda Open
Background Brucellosis is a significant but under-reported bacterial zoonosis in Rwanda. Despite recognition as one of Rwanda's top six priority zoonotic diseases in 2019, comprehensive epidemiological data linking human and animal infecti…

Reducing the threats of rodent-borne zoonoses requires an understanding and leveraging of three key pillars: disease ecology, synanthropy, and rodentation Open
Rodents have co-existed with humans for centuries, and frequently exchange pathogens. Historically, rodent-driven plague outbreaks scoured the Old World, resulting in substantial human mortality. Although such pandemics have not occurred f…

The overlooked conservation value and ecosystem services of saline lakes Open
Saline lakes are hypersensitive to changes in their water balance and therefore show amplified responses to climatic and land-use changes in their catchment. However, despite the resulting, often dramatic ecological consequences, saline la…

Identifying weather patterns affecting household date palm sap consumption in Bangladesh, 2013–2016 Open
Nipah virus spillovers via consumption of date palm sap in Bangladesh vary substantially between years and have been associated with lower winter temperatures and precipitation. However, the mechanisms driving the interannual variation and…

Seroprevalence and risk factors for brucellosis amongst livestock and humans in a multi-herd ranch system in Kagera, Tanzania Open
Background Brucellosis remains a significant health and economic challenge for livestock and humans globally. Despite its public health implications, the factors driving the endemic persistence of Brucella at the human-livestock interface …

Empirical and model-based evidence for a negligible role of cattle in peste des petits ruminants virus transmission and eradication Open
Peste des petits ruminants virus (PPRV) is a multi-host pathogen with sheep and goats as main hosts. To investigate the role of cattle in the epidemiology of PPR, we simulated conditions similar to East African zero-grazing husbandry pract…

Modeling the dietary effects on bat viral shedding and potential consequences for pathogen spillover Open
Changes in the quality and quantity of food resources can affect individuals’ health, the way they control infections and consequently the likelihood of onward transmission of pathogens. Dietary shifts have been proposed as one of the fact…

Ecological countermeasures to prevent pathogen spillover and subsequent pandemics Open
Substantial global attention is focused on how to reduce the risk of future pandemics. Reducing this risk requires investment in prevention, preparedness, and response. Although preparedness and response have received significant focus, pr…

Investigating tritrophic interactions using bioenergetic demographic models Open
A central debate in ecology has been the long‐running discussion on the role of apex predators in affecting the abundance and dynamics of their prey. In terrestrial systems, research has primarily relied on correlational approaches, due to…
View article: Periodic shifts in viral load increase risk of spillover from bats
Periodic shifts in viral load increase risk of spillover from bats Open
Prediction and management of zoonotic pathogen spillover requires an understanding of infection dynamics within reservoir host populations. Transmission risk is often assessed using prevalence of infected hosts, with infection status based…

SARS-CoV-2 Omicron (B.1.1.529) Infection of Wild White-Tailed Deer in New York City Open
There is mounting evidence of SARS-CoV-2 spillover from humans into many domestic, companion, and wild animal species. Research indicates that humans have infected white-tailed deer, and that deer-to-deer transmission has occurred, indicat…

Evaluating noninvasive methods for estimating cestode prevalence in a wild carnivore population Open
Helminth infections are cryptic and can be difficult to study in wildlife species. Helminth research in wildlife hosts has historically required invasive animal handling and necropsy, while results from noninvasive parasite research, like …

Density dependent environments can select for extremes of body size Open
Body size variation is an enigma. We do not understand why species achieve the sizes they do, and this means we also do not understand the circumstances under which gigantism or dwarfism is selected. We develop size-structured integral pro…

Nipah Virus Detection at Bat Roosts after Spillover Events, Bangladesh, 2012–2019 Open
Knowledge of the dynamics and genetic diversity of Nipah virus circulating in bats and at the human-animal interface is limited by current sampling efforts, which produce few detections of viral RNA. We report a series of investigations at…

Fostering landscape immunity to protect human health: A science‐based rationale for shifting conservation policy paradigms Open
Anthropogenic land use change is a major driver of zoonotic pathogen spillover from wildlife to humans. According to the land use‐induced spillover model, land use change alters environmental conditions that in turn alter the dynamics betw…

Examination of the interaction between age‐specific predation and chronic disease in the Greater Yellowstone Ecosystem Open
Predators may create healthier prey populations by selectively removing diseased individuals. Predators typically prefer some ages of prey over others, which may, or may not, align with those prey ages that are most likely to be diseased. …
