Abstract

ABSTRACT Because temperature and salinity affect life cycle of copepods, the aim was to determine the influence of both factors upon postembryonic development ofBoeckella poopoensis. Bioassays with 5, 10, 20, 30, and 35 g/Lat 15° and 22°C were carried out. At 15°C, specimens needed 21-26 days to complete its development in the four lower salinities, but did not pass from naupliar stages in 35 g/L. At 22°C complete development fluctuated from 13 (5, 10, and 20 g/L) to 22 and 41 days (30 and 35 g/L). The greatest mortality was registered at higher salinities, especially at 15°C, as lower metabolism may not have contributed sufficient energy for osmoregulation. Though it is a halotolerant species, low temperatures could reduce its tolerance, suggesting that this factor would limit its distribution in South America (nowadays up to 43°S). Changes in these conditions due to global warming could allow its advancement to the South.

温度和盐度对新热带鱿鱼类poopoensis Boeckella胚胎后发育的影响(甲壳纲，桡足目)

由于温度和盐度影响桡足类动物的生命周期，目的是确定这两个因素对poopoensis boeckella胚胎后发育的影响。以5、10、20、30和35 g/ l15°和22°C进行生物测定。在15°C时，在4种较低盐度下，标本需要21-26天才能完成发育，但在35 g/L的盐度下，标本不能从无肢阶段通过。在22°C下，完全发育从13天(5、10和20 g/L)波动到22天和41天(30和35 g/L)。在较高的盐度下，特别是在15°C时，死亡率最高，因为较低的新陈代谢可能没有为渗透调节提供足够的能量。虽然它是一种耐盐物种，但低温可能会降低它的耐受性，这表明这一因素将限制它在南美洲的分布(现在高达43°S)。由于全球变暖导致的这些条件的变化可能会使其向南移动。

期刊介绍： Marine and Freshwater Behaviour and Physiology is devoted to the publication of papers covering field and laboratory research into all aspects of the behaviour and physiology of all marine and freshwater animals within the contexts of ecology, evolution and conservation. As the living resources of the world’s oceans, rivers and lakes are attracting increasing attention as food sources for humans and for their role in global ecology, the journal will also publish the results of research in the areas of fisheries biology and technology where the behaviour and physiology described have clear links to the contexts mentioned above. The journal will accept for publication Research Articles, Reviews, Rapid Communications and Technical Notes (see Instructions for authors for details). In addition, Editorials, Opinions and Book Reviews (invited and suggested) will also occasionally be published. Suggestions to the Editor-In-Chief for Special Issues are encouraged and will be considered on an ad hoc basis. With the goal of supporting early career researchers, the journal particularly invites submissions from graduate students and post-doctoral researchers. In addition to recognising the time constraints and logistical limitations their research often faces, and their particular need for a prompt review process, accepted articles by such researchers will be given prominence within the journal (see Instructions for authors for details).
