深海木落生态系统研究进展
A review of recent researches on wood-fall ecosystem in deep sea
摘要
Abstract
Wood-fall is an important organic matter and energy source in oligotrophic deep-sea environment,which has important impacts on biodiversity,species evolution and biogeochemical cycle.We reviewed recent research advances of deep sea wood-fall ecosystem from the following aspects:(1)The source,formation and ecological characteristics of deep sea wood-fall ecosystem;(2)The biodiversity,community composition and driving factors of deep sea wood-fall;(3)Ecological functions of deep sea wood-fall.In general,wood-fall ecosystem is a highly fragmented island-like ecosystem,which creates biodiversity hotspots in the oligotrophic seafloor by attracting spe-cific benthic organisms and chemosynthetic microorganisms in deep sea.The unique three-dimensional structure of wood-fall can provide habitat and shelter for deep sea organisms,and promote the evolution of new species.The wood-fall is also a"stepping stone"for the migration and dispersal of species in the chemosynthetic ecosystem.The diversity and community structure of benthic organisms and microorganisms in deep sea wood-fall are influenced by environmental factors and ecosystem carriers.Moreover,chemosynthetic microorganisms in the wood-fall ecosystem can participate in the deep-sea biogeochemical cycling,especially the carbon cycle and sulfur cycle,through diverse pathways.Herein,we suggest to further study the deep-sea wood-fall ecosystem from the following aspects:(1)The community structure and ecological succession of deep sea wood-fall ecosystem;(2)The novel microor-ganisms and related functional genes related to cellulose degradation in the deep sea wood-fall ecosystem;(3)The driving mechanism of deep sea wood-fall microbiome on biogeochemical cycles.关键词
