Increasing surface sea water temperatures effect on growth, reproduction and development in marine organisms. Sea urchins are excellent indicator species and ideal model organisms to focus on. In this study, I tested the effect of higher temperatures on reproductive functions, heat shock protein (HSP, a chaperone protein produced by cells in response to heat stress) and nitrotyrosine protein (NTP, an indicator of reactive nitrogen species, RNS) expressions, cellular apoptosis, and ceolomic fluid (CF, a body fluid which regulates important physiological processes) conditions in Atlantic sea urchin at three different temperatures. Ten sea urchins were placed in each of six aquariums with temperatures of 24 °C (Control), 28 and 32 °C (Higher temperatures) under controlled laboratory conditions for 7 days. Collectively, the results suggest that elevated water temperature acidify CF pH, and increase oxidative stress and cellular apoptosis which might be involved in the impairment of reproductive functions in Atlantic sea urchin.
