WebApr 11, 2024 · Increased temperature and acidification have an additive effect in increasing respiration in sea urchins [22,28]. It will be important to understand the metabolic … WebApr 27, 2024 · The seawater temperature in each vessel was adjusted using temperature-controlled water baths (Aqua, Tokyo) with an accuracy of 0.3°C. The optimal temperature for sea urchin embryogenesis was defined as the temperature at which the embryos were able to develop into gastrulae without any deformities [ 9, 10 ].

WebJun 29, 2010 · Increased temperature (+3°C) stimulated growth, producing significantly bigger larvae across all pH/ PCO2 treatments up to a thermal threshold (+6°C). Increased acidity (-0.3-0.5 pH units) and hypercapnia significantly reduced larval calcification. A +3°C warming diminished the negative effects of acidification and hypercapnia on larval growth. WebMay 26, 2004 · Sea urchins are one organism that is affected by temperature. A temperature- dependent period exists after egg fertilization in which the duration of the cleavage cycle and normal development patterns are affected by the temperature of the surrounding environment (Yamada, K, and K. Mihashi, 1998). WebIt is well known that development of sea urchin eggs and embryos is influenced by the temperature of the sea water. Generally, embryos develop relatively faster at high temperatures. Most sea urchin species have a specific breeding season. It is interesting that exogastrulation is induced by culture of embryos at temperatures pop toy company
