What are “marine meiofauna”? - NOAA Ocean Exploration
网页2022年5月19日 · Marine meiofauna are a group of animals small enough to live in between the grains of sand and mud on the seafloor. After sediment samples are washed and the meiofauna has been extracted from most of the sediment grains, the microscopic organisms can be seen under the stereomicroscope.
Meiofauna - an overview | ScienceDirect Topics
网页Meiofauna define a diverse assemblage of minute invertebrates generally associated with the benthos, or bottom, of many streams and rivers. Meiofauna can be considered intermediaries between microbes and macroscopic organisms in stream food webs. In this chapter, we detail how to sample, identify, and quantify these tiny animals.
Meiobenthos - Wikipedia
网页Meiobenthos, also called meiofauna, are small benthic invertebrates that live in marine or freshwater environments, or both. The term meiofauna loosely defines a group of organisms by their size—larger than microfauna but smaller than …
Meiofauna: Biodiversity, Ecology, and Role in Ecosystems - MDPI
网页2023年9月1日 · The main diversity of meiofauna in most biotopes consists of representatives of segmented worms (type Annelida mainly Subclass Oligochaeta), nematodes (type Nematoda), rotifers (type Rotifera), and arthropods: harpacticoids (class Copepoda, order Harpacticoida), ostracods (class Ostracoda), water mites (class Arachnida, order Trombidiformes) .
Characteristics of meiofauna in extreme marine ecosystems: a …
网页2017年11月17日 · In this review, we present an integrated view of the biodiversity, ecology and physiological responses of marine meiofauna inhabiting several extreme marine environments (mangroves, submarine caves, Polar ecosystems, hypersaline areas, hypoxic/anoxic environments, hydrothermal vents, cold seeps, carcasses/sunken woods, deep-sea canyons, deep ...
Meiofauna matters: The roles of meiofauna in benthic ecosystems
网页2018年5月1日 · Meiofauna activities modify a series of physical, chemical and biological sediment properties. They often do so simultaneously by, for example, displacing sediment grains during burrow construction and displacing organic matter and microorganisms within the sediment matrix during feeding.
Meiofauna: Current Biology - Cell Press
网页2024年3月25日 · In well-sorted, subtidal, organic-rich shell hash and coral reef rubble, the abundance of meiofauna can be breathtaking, with a million or more individuals and over 100 species per liter. Meiofauna may be the most phylogenetically dense animal communities on the planet.
Deep-Sea Meiofauna—A World on Its Own or Deeply Connected?
网页2023年3月24日 · Those tiny animals, the size of a sand grain or smaller, can make a meaningful contribution to ecological processes on such a vast scale. Ubiquity and abundance, two important characteristics of meiofauna worldwide, make these organisms an essential part of deep-sea habitats and ecosystems.
Biodiversity estimates and ecological interpretations of meiofaunal ...
网页2018年8月14日 · Here, we compare biodiversity assessments of a diverse meiofaunal community derived by applying multiple taxonomic methods based on comparative morphology, molecular phylogenetic analysis, DNA...
Meiofauna in a changing world - ScienceDirect
网页2022年5月1日 · The importance of meiofauna in aquatic ecosystems, from the sediments of inland waters to those of deep-sea environments, results from an intricate web of relationships that collectively affect a range of ecosystem processes, including several that contribute to important ecosystem services (Schratzberger and Ingels, 2018).
