宏观生态学主要关注理解生物体丰度和分布的大规模模式，并确定这些模式是如何产生的。虽然陆地和淡水生态学领域的宏观生态学研究比比皆是，但利用海洋数据进行的类似研究却很少。我们研究了 95 种河口大型无脊椎动物的平均生物丰度与栖息地占用范围之间的关系，对英国各地 143 个 1 公里的网格进行了普查。结果表明，丰度和占有率之间存在显着的正相关关系，并且这种关系的斜率在分类组之间没有显着差异。与具有其他生殖/传播生物的类群相比，具有浮游/卵磷脂幼虫的类群在丰度占用斜率上没有显着差异。观察到的模式与许多陆地和淡水类群研究中报告的模式一致。
Macroecology is essentially concerned with understanding the large-scale patterns in organisms' abundance and distribution, and determining how these patterns arise. Whilst macroecological studies abound in terrestrial and freshwater ecology, few comparable studies have ever been conducted using marine data. We examined the relationships between mean organismal abundance and the extent of site occupancy of 95 species of estuarine macroinvertebrates, censused over 143 grid squares of 1 km spread across the UK. A significant positive relationship between abundance and occupancy was revealed, with the slope of this relationship not differing significantly between taxonomic groups. Taxa with planktonic/lecithotrophic larvae showed no significant difference in abundance-occupancy slope compared to taxa with other reproductive/dispersal biologies. The patterns observed are consistent with those reported in many studies of terrestrial and freshwater taxa.
