Consider the effects of the same climate change scenario (+3°C) for a small frog with high cutaneous resistance, Litoria bicolor and cane toads Rhinella marina . The characteristics of the 3 species are show in the table below. The main differences among these 3 spreadsheets are the body masses and cutaneous resistances. Another difference is that, unlike Litoria caerulea, the other two species are assumed to be outside during the day rather than in a tree hollow. The wind speed inside a hollow is very low, and the humidity is higher. But the air temperatures are the same for all 3 models. Under the climate change scenario, were these 2 species exposed to lethal conditions for either water loss or body temperature? Species Mass (g) Cutaneous resistance (s/cm) Critical Thermal Maximum Temperature (°C) Litoria caerulea 50 14 37.5 Litoria bicolor 1 63 41.0 Rhinella marina 1, 50 or 500 1.7 37.5
