Prevalence of Gastrointestinal Parasitic Infections in Captive Snakes, Bangladesh. [PDF]

Vet Med Sci
This study documented gastrointestinal parasitic infections in captive venomous and non‐venomous snakes in Bangladesh for the first time, finding an overall prevalence of 39.1%, with helminths more common than protozoa. Non‐venomous snakes and juveniles were most susceptible, while controlled terrarium housing reduced risk, highlighting the need for ...

Comparison of Corticosterone Concentrations in Dermal Secretions and Urine in Free-Ranging Marine Toads (Rhinella marina) in Human Care. [PDF]

Vet Med Int, 2023
Corticosterone concentrations have been measured in amphibians by collecting blood or urine samples. However, blood sampling is invasive, and urine can be difficult to collect. A novel method of swabbing the skin of an amphibian has been utilized in numerous species but has not been verified in marine toads (Rhinella marina).

Scientists' Warning on the Rapid Evolution of Parasites in the Anthropocene. [PDF]

Evol Appl
ABSTRACT Human activities are changing the natural world at an accelerating pace, and as a consequence exerting novel and often strong selection pressures on living organisms. For species with traits conferring huge inherent evolutionary potential, like parasites, the outcome may be rapid adaptive responses spanning multiple phenotypic traits. The rise

Divergence in host–parasite interactions during the cane toad's invasion of Australia

Ecology and Evolution, 2022
Coevolutionary host–parasite “arms races” can be disrupted by new evolutionary forces imposed by biological invasions, affecting both host and parasite densities, as well as their traits.
