Table S1. Conditions within Connecticut study ponds during an enclosure experiment carried out between 22 April and 6 June, 2013. Ponds are categorized according to the presence or absence of wood frog eggs and larvae. Maximum water depth was measured in cm and all other responses were measured at the point of maximum depth. Water temperature (Temp) was measured in degrees C, Total Dissolved Solids (TDS) in ppm, Conductivity in uS/m, Dissolved Oxygen (DO) in mg/l and Surface Area in square meters. Responses shown as means + SE were measured on at least 5 and up to 7 dates in each pond. Surface area was measured at the beginning of the experiment. Two ponds (Bailey, State St.) dried early and therefore measurements were not possible. Instruments used included a Yellow Springs Instruments 550A dissolved oxygen/temperature meter, an Oakton Instruments Waterproof pHTestr1 meter, and a Oakton Instruments Waterproof TDSTestr 3 meter.
