Host and parasite thermal ecology jointly determine the effect of climate warming on epidemic dynamics

Corresponding Author: Alyssa Gehman, alyssamina@gmail.com Summary Writer: Trippe Ross, tross312@uga.edu Host organisms and their parasites undergo physiological changes in response to climate warming, and these responses may alter the spread and transmission of infectious diseases.  Ectotherms are especially sensitive to environmental temperature, and climate warming may reduce or increase disease […]

Learning infectious disease epidemiology in a modern framework

Infectious disease modeling is a critical skill, and although not all students will model infectious diseases directly, many will become the consumer of such models and will need to understand the models conceptually. This makes infectious disease modeling a useful tool for all students to learn, but many students in […]

Non‐native parasite enhances susceptibility of host to native predators

Parasites often alter host physiology and behavior, which can enhance predation risk for infected hosts. Higher consumption of parasitized prey can in turn lead to a less parasitized prey population (the healthy herd hypothesis). Loxothylacus panopaei is a non-native castrating barnacle parasite on the mud crab Eurypanopeus depressus along the […]

Environmental Persistence Influences Infection Dynamics for a Butterfly Pathogen

Many pathogens, including those infecting insects, are transmitted via dormant stages shed into the environment, where they must persist until encountering a susceptible host. Understanding how abiotic conditions influence environmental persistence and how these factors influence pathogen spread are crucial for predicting patterns of infection risk. Here, Richard Hall and […]

Ecological utility theory: Solving a series convergence issue

Utility analysis is quite useful in quantifying direct and indirect species relations in a compartmental ecosystems model, regardless of its size or complexity. It serves as a basis for the formulation of system-wide synergism and mutualism measures. A significant issue that limits the applicability of utility analysis is that its […]

Fine-scale variation in microclimate across an urban landscape shapes variation in mosquito population dynamics and the potential of Aedes albopictus to transmit arboviral disease

Environmental factors influence the dynamics of mosquito-borne disease transmission. Most models used to predict mosquito-borne disease transmission incorporate climate data collected at coarser scales than mosquitoes typically experience. Climate conditions can vary greatly between indoor and outdoor environments, and are influenced by landscape features. We conducted a field experiment with […]
