落在深海海底的木材福尔斯是进入食物有限的深海的重要能源。独特的社区，主要是木材和硫化物专性物种形成这些木材福尔斯。然而，人们对伐木群落的组成在空间和时间上的变化模式和驱动因素知之甚少，因此，对伐木福尔斯如何促进深海生物多样性知之甚少。十八相思日志不同的大小放置和检索后五年在3200米的网站在太平洋。我们发现，分类组成和结构的深海木材下降社区变化很大，等同于相当大的差异，能源的使用和可用性。我们的研究结果表明，木材福尔斯的自然变异可能对深海多样性有重大贡献。
Wood falls on the deep-sea floor represent a significant source of energy into the food-limited deep sea. Unique communities of primarily wood- and sulfide-obligate species form on these wood falls. However, little is known regarding patterns and drivers of variation in the composition of wood fall communities through space and time, and thus, how wood falls contribute to deep-sea biodiversity. Eighteen Acacia logs varying in size were placed and retrieved after five years at a 3200 m site in the Pacific Ocean. We found that the taxonomic composition and structure of deep-sea wood fall communities varied considerably and equated with considerable differences in energy usage and availability. Our findings suggest that natural variability in wood falls may contribute significantly to deep-sea diversity.
