Biomass of experimental marine invertebrate communities across latitude (Competition and Predation across Latitude)

<p>Biomass of sessile marine invertebrates from coastal sites across a latitudinal gradient spanning the subarctic to the tropics. Biomass of each community was measured after a developmental period of three or 12 months under nine different treatments that tested the effect of predation and competition. Caging was used to reduce predation pressure and biomass removals opened up space, a limiting resource in sessile communities.</p>本数据集涵盖了横跨亚北极至热带的纬度梯度沿海生境中的固着海洋无脊椎动物（sessile marine invertebrates）生物量。各群落的生物量在经历3个月或12个月的发育周期后，通过9种不同实验处理完成测定，这些处理旨在探究捕食作用与种间竞争的效应。实验采用笼网设置以降低捕食压力，而移除生物量则可开辟空间——该空间是固着群落的限制性资源。
