About key messages

Key messages provide a descriptive index to studies we have found that test this intervention.

Studies are not directly comparable or of equal value. When making decisions based on this evidence, you should consider factors such as study size, study design, reported metrics and relevance of the study to your situation, rather than simply counting the number of studies that support a particular interpretation.

Supporting evidence from individual studies

  1. A controlled laboratory study conducted between 1976 and 1977 on specimens from a river in Virginia, USA (Cherry et al. 1980) found that exposure to temperatures of 36°C and higher killed Asian clams Corbicula fluminea. All clams were dead after either four days at 36°C or two days at 37°C compared with clams surviving in a control treatment at 25°C. Clams were placed in seven heated aquatic chambers, plus one control chamber. In total, 19 clams were placed in each chamber. Over a 24-hour period, infrared lamps raised chamber temperatures to 27, 29, 31, 33, 35, 36 and 37°C. These temperatures were held for four days. A control group was maintained at 25°C. Mortality status of clams was checked and recorded.
