چکیده
Meiofauna are an excellent assemblage for studying how environmental changes affect numerous invertebrates. Meiofaunal distribution can be influenced by several key factors which may differ among habitats and could too to evaluate. The Wagner Consag shallow basins located at the northern end of Gulf California. These a young rift system where intense gas discharge has been reported correlated anomalously high heat flow (105 W/m2) temperature (50.2°C in this study). aim study is evaluate effects conditions on abundance biomass meiofauna these two geologically anomalous determine measured variables factors. Sediment samples were collected during “Sísmica 2015” expedition aboard R/V “Alpha Helix” September 2015, within depth range 39–237 m. A total 609 organisms separated six taxonomic groups identified: Gastropoda, Polychaeta, Nematoda, Kinorhyncha, Ostracoda, Harpacticoida. ranged from 0 114.11 ind/10 cm2 300.02 μg Corg/10 cm2. Though found sediment temperature, main factor associated with observed meiofaunal was grain size however, confirmed as most important it responsible greatest spatial variation composition throughout basins, stations showed lower abundances. There still very little known about extreme environments their clear responses lacking published literature. urgent need understand biology ecology taxa that thrive natural environments. findings provide some insights into ecological processes, but more importantly they use assessing vulnerability benthic communities future anthropogenic disturbances.
