Our understanding of continental shelf meiofaunal communities is rudimentary, but it seems likely that winter storms are a major organizing force. In temperate and boreal waters, storms are frequent, large in spatial extent, and capable of eroding sediment. Given the vertical distribution of meiofauna in the sediment, most could be eroded by winter storms. If it can be shown that species are adapted either to avoid erosion or to benefit from it, then storms may be implicated in community organization. Dr. Thistle proposes to determine whether species present at a shelf site during winter avoid erosion. For those that do, he will test whether the energetic cost of being in the water column underlies the adaptation. For those that do not avoid erosion, he will test whether the water column is a place of opportunity, at least in terms of their ability to increase their energy reserves. Although there are other possible consequences, these are likely impacts and provide a place to begin an inquiry into storm effects on the organization of shelf meiofaunal communities.

Thistle博士建议确定是否 冬季在大陆架栖息的物种避免了侵蚀。 对于那些这样做的人，他将测试是否能源成本 在水柱中是适应的基础。 对于那些 不避免侵蚀，他将测试水是否 专栏是一个充满机会的地方，至少在他们的 增加能量储备的能力。 虽然有 其他可能的后果，这些是可能的影响， 提供一个地方，开始调查风暴对 大陆架小型底栖动物群落的组织。
