This study investigated the effects of climate change related environmental variation on growth, survivorship, and morphological plasticity of the harpacticoid copepod Tisbe biminiensis. Three experiments were conducted to determine the response to altered pH and temperature. Individuals were reared in laboratory conditions, in artificial seawater at combinations of one of two temperatures conditions (25°C and 34°C), and at either ambient or future pCO2 conditions (~400 utm and ~1000 utm). Post-hatch measurements for growth and morphology were obtained at intervals of twelve hours for subsamples of the cultures with data collection using microscopy and thin plate spline morphometric techniques.
