Article Synopsis
- Parasites are common but measuring their impact on host organisms is complex; using metabolic theory of ecology (MTE) helps quantify energy loss to parasites.* -
- Research indicates that a single tapeworm can take up to 32% of its stickleback fish host's energy, and multiple parasites can extract up to 46% without increasing the host’s respiration rate.* -
- The study highlights the potential of MTE as a more precise tool for understanding the energetic effects of parasitism on ecosystems, suggesting that future research should explore these dynamics further.*
The human burden of environmentally transmitted infectious diseases can depend strongly on ecological factors, including the presence or absence of natural enemies. The marbled crayfish (Procambarus virginalis) is a novel invasive species that can tolerate a wide range of ecological conditions and colonize diverse habitats. Marbled crayfish first appeared in Madagascar in 2005 and quickly spread across the country, overlapping with the distribution of freshwater snails that serve as the intermediate host of schistosomiasis-a parasitic disease of poverty with human prevalence ranging up to 94% in Madagascar.

- Scientists are studying how many parasites live in coral reefs and why it's hard to predict their numbers.
- They looked at different factors like island size, human population, and fish types to understand what affects parasites.
- They found that the location of islands was really important, and that different types of parasites behave differently based on how complex their life cycles are.
