生态区是根据群落结构定义的，是非生物或甚至是人为强迫的函数。它们是中尺度结构，定义为物种的潜在栖息地或预测的群落地理范围。我们假设它们可以更容易地定义为海洋环境中的长寿物种，如底栖动物或浅海鱼类。中上层领域存在不确定性，因为它具有较高的变异性，加上对中层和底层区域知之甚少。不断变化的环境和栖息地的改变可能会促使新的群落从浮游生物到鱼类或顶级捕食者。我们需要基线研究，如南极海洋生物普查的研究，以及像SCAR-MarBIN这样的数据库，作为整合所有这些观测的工具。我们的目标是了解南大洋的生物多样性模式，以及这些模式可能如何随着时间的推移而变化。

Ecoregions are defined in terms of community structure as a function of abiotic or even anthropogenic forcing. They are meso-scale structures defined as the potential habitat of a species or the predicted communities geographic extent. We assume that they can be more easily defined for long-lived species, such as benthos or neritic fish, in the marine environment. Uncertainties exist for the pelagic realm because of its higher variability, plus little is known about the meso- and bathypelagic zones. A changing environment and modification of habitats will probably drive new communities from plankton to fish or top predators. We need baseline studies, such as those of the Census of Antarctic Marine Life, and databases like SCAR-MarBIN as tools for integrating all of these observations. Our objective is to understand the biodiversity patterns in the Southern Ocean and how these might change through time.
