A Herpetological Survey of the James Bay Area of Québec and Ontario

In May-June 2002, as part of a survey of a variety of taxa in the James Bay region of Ontario and Québec, we surveyed the poorly documented herpetofauna of this region. In Ontario we visited sites near Moosonee that FWS had previously surveyed in 1971-1972, and continued ongoing herpetological monitoring around Cochrane. In Québec we surveyed the inland James Bay Road, and roads to four settlements along the coast. American Toad (Anaxyrus americanus), Spring Peeper (Pseudacris crucifer), and Wood Frog (Lithobates sylvaticus) were widespread and abundant throughout. Blue-spotted Salamander (Ambystoma laterale) and Garter Snake (Thamnophis sirtalis) were widespread and common in Québec and at the study site near Cochrane. We obtained the first taped calls and voucher specimen of the Boreal Chorus Frog (Pseudacris maculata) from Québec, and failed to find it at the settlement and airport of Moosonee where it had been present in 1972. A significant range extension was for the Two-lined Salamander (Eurycea bislineata), which we found 200 km north of its previously known range in northwestern Québec. Despite extensive searches, the species was not found north of 52°05'N. The Mink Frog (Lithobates septentrionalis) was widespread and relatively common in Québec, but was sought but not found in Ontario. The Leopard Frog (Lithobates pipiens) was only found at two Québec sites, including one where it was reported in 1974, but it has not been found at any of the Ontario sites where it was found in the 1970's. We present some suggestions for the further study of the herpetofauna of the area, and review evidence for contacts between eastern and western lineages of widespread species.En mai et juin 2002, dans le cadre d'un inventaire faunique dans la région de la baie James, en Ontario et au Québec, nous avons inventorié la faune herpétologique, laquelle est très peu documentée dans cette région. En Ontario nous avons visité des sites près de Moosonee, que l'un de nous (FWS) avait inventorié en 1971-1972, puis nous sommes allés aux environs de Cochrane. Au Québec l'inventaire s'est majoritairement fait le long de la route de la baie James et des routes d'accès aux villages. Le Crapaud d'Amérique (Anaxyrus americanus), la Rainette crucifère (Pseudacris crucifer) et la Grenouille des bois (Lithobates sylvaticus) sont répandus et communs sur toute l'aire d'étude. La Salamandre à points bleus (Ambystoma laterale) et la Couleuvre rayée (Thamnophis sirtalis) sont répandues et
