Variability in the spatial and temporal distribution of mesozooplankton abundance N Alboran Sea (SW Mediterranean) was assessed intermittently from 2010 to 2020, compared with 1992–2000 historical time series data. Total significantly higher coast than shelf slope waters. There were significant differences between 2010–2020 at three zones. Copepods dominated during winter spring, but cladoceran...

We tested the hypothesis that rotifer species in the microand mesozooplankton are a potential food source for zebra mussels. We labeled phytoplankton with 14C, fed them to two species of rotifers (140–210 mm length) that were previously found abundantly in the Hudson River and had declined following a zebra mussel invasion, and estimated the assimilation of carbon. Assimilation efficiencies wer...

Density dependence is a fundamental concept for fish population dynamics. Although density-dependent growth and maturity among older juveniles adults important regulating size fisheries management, the mechanism of density marine fishes remains unclear. Here, we examined changes in Japanese sardine with increasing abundance beginning 2010 s how current pattern differs from that previous stock-i...

Global warming is increasing the frequency and severity of marine heat waves, which poses a serious threat to ecosystem. This study analyzes seasonal interannual dynamics in abundance structure mesozooplankton community Sevastopol Bay based on bi-monthly routine observations over 2003–2014. The focus impact summer 2010 wave (MHW2010) crustaceans belonging different ecological groups. As respons...

Gelatinous zooplankton (GZ) populations are sensitive to climate change such as environmental perturbations, and spatial changes in their abundance biomass may be associated with degraded biota conditions. Big data time series of GZ abundances were used analyze the annual population dynamics gelatinous well mesozooplankton southern Caspian Sea, Iran from 1996, 2001-2006, 2008-2013 2018-2019. Th...
