Article Synopsis
- Demographic rescue involves adding individuals to endangered populations to boost their numbers and prevent extinction, but its effectiveness is uncertain in the presence of diseases.
- A study was conducted using an aquatic crustacean, Daphnia dentifera, and a fungus pathogen, Metschnikowia bicuspidata, to investigate how pathogens affect demographic rescue outcomes.
- Results showed that while adding healthy individuals temporarily increased population size, populations with infected individuals ultimately had significantly lower abundance compared to those with no intervention, highlighting the risks of introducing diseased organisms during rescue efforts.*
Seawater intrusion associated with decreasing groundwater levels and rising seawater levels may affect freshwater species and their parasites. While brackish water certainly impacts freshwater systems globally, its impact on disease transmission is largely unknown. This study examined the effect of artificial seawater on host-parasite interactions using a freshwater snail host, Biomphalaria alexandrina, and the human trematode parasite Schistosoma mansoni.
