چکیده مقاله:

Climate change is driving changes in the physical and chemical properties of the ocean that have consequences for marine ecosystems and subsequently for marine organisms in every aspects of their lives specially when they are in the most vulnerable stages of their lives. To examine the impacts of this rising temperature on marine organisms we chose barnacle as our experimental models. After the adults acclimated to laboratory situations we collect the larvae and divided them into four Aquariums with different temperatures: The first aquarium as the Control with the same temperature of the Laboratory (which in that temperature, the adult ones breed (27◦C aerated fresh sea water)). The second one that we called it treatment A with 34◦C aerated fresh sea water and the third and fourth aquariums respectively named as Treatment B and Treatment C with 29 and 38◦C sea water. After transporting the larvae to our treated aquariums we fed them with Chaetoceros Algae every day. From Day-2 we collected three larvae from each aquariums and measured their lengths; Changes in the larvas‟ sizes showed in diagram that we‟ve brought in the top of this page. Larvae of the treatment 3 all died after Day-4 and the other groups of larvae in other Treatments showed less growth than the Control. These results may indicate that in higher temperatures for fighting the cost of using more energy that they need for their metabolisms they decreased their growth or the whole energy used in metabolisms for survival of the animal instead of using in growing processes.
