A Skeletochronological Assessment of Age–Parasitism Relationships in Wood Frogs (Lithobates sylvaticus)

摘要: Abstract Amphibian parasite communities are often suggested to be dependent on host size. However, age-related differences in exposure and susceptibility could lead parasitism unaccounted for by To address these hypotheses, we determined the ages of Wood Frogs (Lithobates sylvaticus) using skeletochronology assessed relationships age size with helminth infections. Neither nor was significantly related species richness. Total infection intensity increased female generally males. overall measures may mask more complex dynamics individual species. Although Alaria spp. males initially, both prevalence ultimately decreased male age. The Fibricola sp. Echinoparyphium rubrum abundance also age, whereas Fi...
