摘要: AbstractAn organism’s physiological processes form the link between its life-history traits and prevailing environmental conditions, especially in species with complex life cycles. Understanding how these respond to changing thereby affecting organismal development, is critical if we are predict biological implications of current future global climate change. However, much our knowledge derived from adults or single developmental stages. Consequently, investigated metabolic rate, organic content, carapace mineralization, growth, survival across each larval stage European lobster Homarus gammarus, reared under predicted ocean warming acidification scenarios. Larvae exhibited stage-specific changes temperature sensitivity their rate. Elevated Pco2 increased C∶N ratios interacted elevated affect mineralization. These were linked concomitant ...
