Summary
We developed CDMetaPOP-Disease, a new computational tool to simulate eco-evolutionary dynamics between wildlife, pathogens, and landscapes. This model links genetics to disease spread, aiding wildlife disease management.
Area of Science:
- Ecological informatics
- Computational epidemiology
- Population genetics
Background:
- Simulating eco-evolutionary feedbacks between wildlife hosts and pathogens in complex landscapes is computationally challenging.
- Existing frameworks lack mechanistic links between disease dynamics, landscape demography, and population genetics.
Purpose of the Study:
- Introduce CDMetaPOP-Disease, an open-source, spatially explicit, individual-based module.
- Mechanistically link individual genotypes to epidemiological transition rates for simulating host disease response strategies (resistance and tolerance).
Main Methods:
- Developed CDMetaPOP-Disease, an individual-based demo-genetic module.
- Verified module against SIR-type models (Nash-Sutcliffe Efficiency >= 0.98).
- Simulated novel pathogen emergence in a bat-pathogen system.
Main Results:
- Achieved high fidelity to theoretical expectations in model verification.
- Demonstrated the tool's capability to track pathogen diffusion and spatial-genetic signatures of host adaptation.
- Showcased the simulation of host resistance and tolerance strategies.
Conclusions:
- CDMetaPOP-Disease provides a flexible platform for investigating complex eco-evolutionary feedbacks.
- The module aids in understanding and managing infectious diseases in realistic landscapes.
- Facilitates research at the intersection of ecological informatics, epidemiology, and population genetics.

Gene Flow
Gene flow is the transfer of genes among populations, resulting from either the dispersal of gametes or from the migration of individuals.
Modeling with Differential Equations
Population dynamics can be described mathematically by considering the population size P(t) as a function of time. The rate of change of the population is then represented by the derivative of P(t). A simple assumption is that the rate of growth is proportional to the size of the population itself. This leads to an exponential growth model, where the population increases rapidly without bound. While this is a useful first approximation, it does not reflect realistic long-term...
Evolution of New Traits in Microbes
Microorganisms evolve rapidly due to their large population sizes and short generation times, often exhibiting measurable changes within days under laboratory conditions. Natural selection acts on standing genetic variation, enabling the retention and amplification of beneficial traits that confer fitness advantages in changing environments.Adaptive Pigment Regulation in RhodobacterIn Rhodobacter, a genus of purple non-sulfur bacteria, light-harvesting pigments such as bacteriochlorophyll and...
