The Arctic Ocean is rapidly changing. Air temperature rising two to four times faster in the than global average, with dramatic consequences for ecosystems. Polar zooplankton species have cope those increasing temperatures, whilst simultaneously facing competition by boreal-Atlantic sister advected into via a stronger Atlantic inflow. To assess sensitivity of and respiration rates dominant ( Calanus hyperboreus , glacialis Paraeuchaeta Themisto libellula ) their co-occurring congeners...
Species identification is pivotal in biodiversity assessments and proteomic fingerprinting by MALDI-TOF mass spectrometry has already been shown to reliably identify calanoid copepods species level. However, data may contain more information beyond mere identification. In this study, we investigated different ontogenetic stages (copepodids C1-C6 females) of three co-occurring Calanus from the Arctic Fram Strait, which cannot be identified level based on morphological characters alone....
Life strategies, ecophysiological performances and diel vertical migration (DVM) of zooplankton key species affect the efficiency strength biological carbon pump (BCP). However, it is unclear to what extent different functional groups BCP. Depth-stratified day night samples (0-800 m) from subtropical South Atlantic were analyzed focusing on calanoid copepod community. Calanoid abundance, biomass distribution species-specific impact passive (fecal pellets) active (via DVM) flux determined....
Abstract Small copepod genera play an important role in marine food webs and biogeochemical fluxes but have been neglected many studies. This is the first study determining biomass, carbon consumption egestion rates of small- (<1 mm prosome length, PL), medium- (1–1.5 PL) large-sized (>2 copepods along a cross-shelf transect southern Benguela upwelling system. Calanoids contributed on average 55 ± 19% to total abundance 82 13% biomass. Small-sized Oithona spp. (114–119 mg C m−2...
Abundance, biomass and respiration rates of dominant medium- to larger-sized copepod species (ML class) from the upwelling system off Peru (8.5-16°S) were determined along with their carbon ingestion egestion rates. Small copepods (S included for comparisons community Overall, abundance/biomass was highest in upper 50 m decreased depth thus also egestion. Ingestion ML class (0-50 m) shelf regions (14-515 mg C -2 d -1 ) lower south compared north central study areas, while offshore (11-502...
