Fig. 3 in Not playing by the rules: Unusual patterns in the epidemiology of parasites in a natural population of feral horses (Equus caballus) on Sable Island, Canada

Fig. 3. Proportions of third-stage larvae of large and small strongyle species cultured from feces of 81 Sable Island horses in summer 2014, showing an unusual dominance of S. equinus in adult horses. Larvae with a rhabditiform pharynx were rare in young (1–3 years) and adult horses (≥3 years), but common in foals, which could represent larvae of Strongyloides westeri.
