Abstract
Climate change creates problems since global warming and ocean acidification can produce significant effects on marine organisms and ocean ecosystems. The aim of this study was to determine how the combination of these two stressors affects fertilization and early embryonic development of the sea urchin Paracentrotus lividus. An experiment with a simultaneous manipulation of the pH and temperature was carried out. In order to do this, the studied variables were fertilization and cell division rates at three different times after insemination. Results showed some tolerance of the species to future climate change scenarios. However, previous studies have found more severe effects at later stages of early embryonic development. In this sense, further research assessing the combined effects of stressors in other life cycles phases is needed.
