The community-wide trophic cascade due to collapsed fish stocks and population outburst of invasive predators after the early 1990s resulted in different pelagic and benthic food web structures in the Black Sea. The northeastern region assumed their most simplified forms characterized by increasing mesozooplankton and polychaete biomass. The ecological degradation is more severe in the northwestern part, whereas the southern basin maintains an anchovy fishery under relatively weak gelatinous predation.

Climatic warming and accompanying changes in the ecological regime of the Black Sea during 1990s Oguz, T; Cokacar, T; Malanotte-Rizzoli, P; Ducklow, HW (2003-09-27) [1] The Black Sea ecosystem is shown to experience abrupt shifts in its all trophic levels from primary producers to apex predators in 1995 - 1996. It arises as a manifestation of concurrent changes in its physical climate introduced by intensive warming of its surface waters as well as abrupt increases in the mean sea level and the net annual mean fresh water flux. The warming is evident in the annual-mean sea surface temperature ( SST) data by a continuous rise at a rate of similar to0.25 degreesC per yea...
Abrupt transitions of the top-down controlled Black Sea pelagic ecosystem during 1960-2000: Evidence for regime-shifts under strong fishery exploitation and nutrient enrichment modulated by climate-induced variations Oguz, Temel; Gilbert, Denis (Elsevier BV, 2007-02-01) Functioning of the Black Sea ecosystem has profoundly changed since the early 1970s under cumulative effects of excessive nutrient enrichment, strong cooling/warming, over-exploitation of pelagic fish stocks, and population outbreak of gelatinous carnivores. Applying a set of criteria to the long-term (1960-2000) ecological time-series data, the present study demonstrates that the Black Sea ecosystem was reorganised during this transition phase in different forms of top-down controlled food web structure th...
Chemical composition, respiration and feeding rates of the new alien ctenophore, Beroe ovata, in the Black Sea Finenko, GA; Anninsky, BE; Romanova, ZA; Abolmasova, GI; Kıdeyş, Ahmet Erkan (2001-05-01) Maximum daily rations of the ctenophore Beroe ovata Brugiere and predatory impacts on the Mnemiopsis leidyi A. Agassiz population were estimated via digestion time, prey biomass and predator and prey density in Sevastopol Bay and adjacent water regions. Digestion times ranged from 0.5 to 5.2 h and depended on the prey/predator weight ratio. Overall, the mean daily ration was 45% of B. ovata wet weight. Preliminary conclusions are given on the B. ovata population as an effective control of the M. leidyi popu...
Interactive Effects of Lake Morphometry and Sticklebacks on the Trophic Position of Arctic charr (Salvelinus alpinus) across Lakes in Western Greenland Arranz, Ignasi; Davidson, Thomas Alexander; Benejam, Lluís; Brucet, Sandra; Sánchez-Hernández, Javier; Landkildehus, Frank; Lauridsen, Torben; Mazzeo, Nestor; Vidal, Nicolas; Özkan, Korhan; Gallego, Irene; Wischnewski, Juliane; Menezes, Rosemberg; Shurkhuu, Tserenpil; Jeppesen, Erik (2022-01-01) The structure and functioning of Arctic ecosystems have been drastically modified by global warming, with fish species potentially performing habitat shifts such as the northern expansion of generalist and warm-adapted species. The freshwater fish species Arctic charr (Salvelinus alpinus, hereafter charr) plays a key role in Arctic lake food webs, but sticklebacks (Gasterosteus aculeatus) may impact the trophic position (TP) of charr by affecting their habitat choice and food resources. In the present study...
DISTRIBUTION OF ANCHOVY EGGS AND LARVAE (ENGRAULIS-ENCRASICOLUS CUV) IN THE BLACK-SEA IN 1991-1992 NIERMANN, U; BINGEL, F; GORBAN, A; GORDINA, AD; Gücü, Ali Cemal; Kıdeyş, Ahmet Erkan; KONSULOV, A; RADU, G; SUBBOTIN, AA; ZAIKA, VE (1994-11-01) Two international surveys of anchovy eggs and larvae were carried out in the Black Sea at the beginning of the spawning season in June 1991 and during the main spawning period in July 1992. Horizontal tows demonstrated that the bulk of anchovy eggs acid larvae were distributed in the upper 3-m layer, but in downwelling areas eggs and larvae were found down to 70 m depth. In contrast to earlier studies, vertical hauls obtained during the present investigation contained higher egg numbers in the southern and ...
