Investigating tri-trophic interactions using bio-energetic demographic models

The paper develops a bioenergetic demographic model to study tri-trophic interactions in Yellowstone, showing that wolf reintroduction reduced elk numbers and increased vegetation biomass.

Density dependent environments can select for extremes of body size

The paper develops size-structured models to explore how density dependence influences body size evolution, showing that gigantism or dwarfism depends on population maturity proportions and developmental trajectories.

Detection of SARS-CoV-2 Omicron variant (B.1.1.529) infection of white-tailed deer

The paper shows SARS-CoV-2 Omicron variant infects white-tailed deer on Staten Island, with age-dependent antibody prevalence and evidence of human-to-deer spillover.

Nipah virus detection at bat roosts following spillover events in Bangladesh, 2012-2019

The paper investigates Nipah virus shedding in bat roosts near human cases in Bangladesh, finding that viral RNA can be detected up to 52 days post-exposure, supporting targeted sampling for better viral ecology understanding.

Multiple spillovers and onward transmission of SARS-Cov-2 in free-living and captive White-tailed deer

SARS-CoV-2 was detected in one-third of sampled white-tailed deer in Iowa between September 2020 and January of 2021 that likely resulted from multiple human-to-deer spillover and deer-to-deer transmission events.

The ecology of Nipah virus in Bangladesh: a nexus of land use change and opportunistic feeding behavior in bats

The paper examines factors driving Nipah virus spillover in Bangladesh, finding winter temperature explains 53% of annual spillover variation and linking land use changes to bat behavior and viral transmission risk.

Principles of resilient coding for plant ecophysiologists

The paper introduces eight coding principles to help plant ecophysiologists write resilient code and presents an R package for plant ecophysiology analysis.

Relationship between Anti-Spike Protein Antibody Titers and SARS-CoV-2 In Vitro Virus Neutralization in Convalescent Plasma

This study finds a strong correlation between anti-RBD and anti-ECD IgG titers and in vitro virus neutralization titers in convalescent plasma, suggesting these titers can serve as surrogates for neutralizing activity.

Identifying age cohorts responsible for Peste des petits ruminants virus transmission among sheep, goats, and cattle in northern Tanzania

This study estimates age-specific force of infection for Peste des petits ruminants virus in Tanzanian livestock using seroprevalence data, finding weak age heterogeneity and suggesting management systems, not age, should guide control efforts.

More than a flying syringe: Using functional traits in vector borne disease research

This paper presents a framework for incorporating vector functional trait variation into disease transmission models to better understand and predict vector-borne disease dynamics.
