Summary
Animal migration affects health and disease spread. This study unifies theory on how migration and parasite interactions shape animal health and disease dynamics, crucial for conservation.
Area of Science:
- Ecology
- Evolutionary Biology
- Parasitology
Background:
- Animal migration significantly influences host health and parasite transmission dynamics.
- Existing research presents disparate findings and theoretical models oversimplify complex ecological interactions.
Approach:
- Systematically reviewed empirical studies on migration and infection across diverse taxa.
- Developed a unified evolutionary framework integrating parasite-host-migration interactions and ecological complexity.
- Generated predictions to guide future research on migration-infection mechanisms.
Key Points:
- Migration influences both individual health and population-level parasite transmission.
- A novel framework explains diverse migration-infection patterns, including partial and differential migration.
- Identified key selective pressures shaping migration in relation to animal health and disease.
Conclusions:
- The developed framework offers an overarching understanding of migration-parasite dynamics.
- This research is critical for predicting how environmental changes may impact migratory species and disease spread.
- Highlights gaps in current knowledge and provides a roadmap for future empirical and theoretical studies.

Excavata is a diverse group of protists that includes both chemoorganotrophic and phototrophic species, with some thriving in anaerobic environments. Among the key groups within Excavata are diplomonads and parabasalids, which are flagellated protists that lack mitochondria and chloroplasts. These microorganisms typically inhabit anoxic environments, such as the intestines of animals, where they exist either symbiotically or as parasites, relying on fermentation for energy production. Some...

8.0K
Migration is long-range, seasonal movement from one region or habitat to another. This common strategy, carried out by many different organisms around the world, is an adaptive response that typically corresponds to changes in an organism’s environment, like resource availability or climate. Migrations can involve huge groups of thousands of animals as well as single individuals traveling alone and can range from thousands of kilometers to just a few hundred meters.

Alveolates are a group of organisms recognized by the presence of alveoli, which are cytoplasmic sacs located beneath the cell membrane. While their function remains uncertain, alveoli may help regulate water balance by controlling how much water enters and leaves the cell. In dinoflagellates, these structures may serve as armor plates. There are three major types of alveolates: ciliates, which move using cilia; dinoflagellates, which use flagella for movement; and apicomplexans, which are...

Symbiotic relationships are long-term, close interactions between individuals of different species that affect the distribution and abundance of those species. When a relationship is beneficial to both species, this is called mutualism. When the relationship is beneficial to one species but neither beneficial nor harmful to the other species, this is called commensalism. When one organism is harmed to benefit another, the relationship is known as parasitism. These types of relationships often...
