During June and July of 1988, 264 amphibians from Algonquin Park, Ontario, were examined for eimeriid coccidian parasites; the species examined were Rana catesbeiana Shaw, Rana clamitans Latreille, Rana septentrionalis Baird, and Rana sylvatica LeConte. Two distinct types of oocysts were observed in the feces of the frogs. The highest prevalence of infection was recorded from young adult frogs and two new species of Eimeria are described from these animals. Oocysts of Eimeria algonquini n.sp. are spherical, 15.8 (14.5–16.1) μm in diameter, with a thin single-layered wall; micropyle and polar granule absent; large granular oocyst residuum present. Sporocysts banana-shaped, 19.5 (18.7–20.4) × 4.2 (3.8–4.6) μm with prominent granular residuum; Stieda body absent. Oocysts of Eimeria kermiti n.sp. are ovoid, 25.1 (24.7–26.6) × 19.5 (17.6–20.1) μm with thin single-layered wall; polar granule present; micropyle absent; large granular oocyst residuum present. Sporocysts ovoid, 9.9 (9.3–10.4) × 6.6 (6.0–7.1) μm with Stieda body and prominent granular residuum.

One hundred and fifty-nine field sites consisting of ditches, bogs, marshes, ponds, and lakes in south and central Nova Scotia were surveyed for the presence of the adults, eggs, or larvae of 11 amphibian species. Water samples were analyzed for pH, alkalinity, color, conductivity, Na, K, Mg, Ca, SO4, and Cl. Discriminant function analysis revealed that none of these variables predicted a species' presence. Two three-species groups were found to be significantly associated among themselves, but mutually exclusive of each other. The two groups were (i) Ambystoma maculatum, Hyla crucifer, and Rana sylvatica and (ii) Rana clamitans, Rana catesbeiana, and Rana palustris. Rana sylvatica and A. maculatum were observed breeding successfully in an acidic bog (mean pH 4.1). Rana clamitans adults and larvae were located in the field at pHs as low as 3.5 and 3.9, respectively. Field transplant studies, using eggs of A. maculatum and R. sylvatica (at pH 5.7 and 4.1) and Bufo americanus (at pH 6.3 and 4.1), revealed that R. sylvatica was least sensitive to acidity. There is considerable variation in acid tolerance among the various species of Nova Scotia amphibians. Nevertheless, successful breeding by some species is occurring at very low pHs.

Two prokaryotic microorganisms were observed in the erythrocytes of frogs in a survey of blood parasites of six species of amphibians from a sphagnum bog adjacent to Lake Sasajewun, Algonquin Park, Ontario. A cytoplasmic virus was observed in 12 of 75 Rana catesbeiana and 1 of 75 Rana septentrionalis. The virus particles were hexagonal in section, measured 300–370 nm in diameter, and occurred in groups that were often surrounded by lamellar arrays of stacked membranes. Large spherical inclusions were seen in the erythrocytes of 2 of 57 Rana clamitans. In the electron microscope these inclusions were found to contain numerous rod-shaped prokaryotes which measured 1–1.7 μm × 200–300 nm. These organisms were ultrastructurally indistinguishable from rickettsiae.
