摘要: Squid are important components of many marine ecosystems from the poles to equator, serving as both predators and prey. Novel aspects their growth reproduction mean that they likely play an role in changing oceans due climate change. Virtually every facet squid life-history examined thus far has revealed incredible capacity this group for plasticity. The extremely fast rates individuals rapid turnover at population level can respond quickly environmental or ecosystem Their ‘life-in-the-fast-lane’ life-style allows them rapidly exploit ‘vacuums’ created when competitors removed. In way, function ‘weeds sea’. Elevated temperatures accelerate life-histories squid, increasing shortening life-spans. At first glance, it would be logical suggest rising water associated with change (if food supply remains adequate) beneficial inshore populations fisheries—growth increase, life spans shorten accelerate. However, response is complex. size hatchlings emerging eggs becomes smaller increase hatchling may have a critical influence on size-at-age achieved adults subsequently, structure. higher egg adult stages opposing forces life-history. process will result squids hatch out earlier, undergo faster over shorter life-spans mature younger size. Individual require more per unit body size, oxygen metabolisms reduced cope without food. It therefore biological, physiological behavioural changes reaching effects.
