The literature on fishers - medium-sized, North American carnivores - is broad, despite being limited, and traditional ecological knowledge of Native Americans contributes to our understanding of fishers. Fishers are generalist predators but also specialized predators of North American porcupines. Over trapping, habitat loss and climate change reduced fisher populations after European colonization of North America. Protection and reintroductions led to general but not to universal population recovery, contributing to the understanding of reintroduction science, including population genetics of both rare and expanding populations. Although adapted to live in old forests with complex structure, some fishers have colonized fragmented habitats, including suburbs. Models of fisher habitat, energetics, sexual dimorphism, genetics, and use of space illustrate the diversity of approaches possible for carnivore studies. Thus, the fisher has become a model organism for ecological and conservation research on mammalian carnivores.
