Foodplant Processing Adaptations in Four \u3ci\u3eHyalophora\u3c/i\u3e Species (Lepidoptera: Saturniidae): Regional and Taxonomic Specialization [PDF]

open access: yes, 2017
To determine whether local populations of four Hyalophora species (Lepidoptera: Satumiidae) had improved survival or were physiologically adapted for rapid and/or efficient growth on their local hosts, a series of larval feeding studies were conducted ...

Seasonal variation in wild pig (Sus scrofa) diet revealed by DNA metabarcoding

open access: yesWildlife Society Bulletin, EarlyView.
Using DNA metabarcoding of fecal samples, we investigated the diet of wild pigs at an extensive bottomland hardwood forest ecosystem within Felsenthal National Wildlife Refuge in Southern Arkansas. We found that wild pig diet was highly diverse and included at least 74 plant families and 106 genera and 23 species of vertebrates.
