The littoral zone of lakes is used as spawning, shelter, or feeding habitat for many fish species and hence is of key importance for overall lake functioning. Despite this, hardly any studies exist examining the long-term dynamics and response of the littoral fish community, composed mostly of juvenile fish, to environmental change. Here, we study the response of total catch per unit effort (CPUE) and individual species CPUE of such a community to 17 years of oligotrophication and examine whether the species responses can be characterised as synchronous or asynchronous.

Vertically-challenged limnology; Contrasts between deep and shallow lakes Moss, B; Beklioğlu, Meryem; Carvalho, L; Kilinc, S; McGowan, S; Stephen, D (Springer Science and Business Media LLC, 1997-01-17) Previous work on a set of small lakes, of varying depth, the meres of North West England, has shown that nitrogen availability controls the summer phytoplankton populations in the deeper ones (max depth > 3 m) and zooplankton grazing in shallow ones. The meres have generally high total phosphorus concentrations and this may be a natural phenomenon dependent on the local geochemistry. Some anthropogenic eutrophication has occurred, however, and from a chain of three meres, sewage effluent was diverted in 199...
Restoration of the eutrophic Lake Eymir, Turkey, by biomanipulation after a major external nutrient control I Beklioğlu, Meryem; Tuzun, I (Springer Science and Business Media LLC, 2003-01-01) Nutrient loading in lakes is recognized as a serious threat to water quality. Over 25 years of raw sewage effluent discharge shifted Lake Eymir from a state dominated by submerged plants to a turbid water state. Successful effluent diversion undertaken in 1995 achieved 88% and 95% reductions in the areal loading of total phosphorus (TP) and dissolved inorganic nitrogen (DIN), respectively. Furthermore, the reduced load of TP was very close to the suggested threshold areal load (0.6 g m(-2) yr(-1)) to attain...
Role of planktonic bacteria in biodegradation of fish-exuded kairomone in laboratory bioassays of diel vertical migration Beklioglu, M; Gözen, Ayşe Gül; Zorlu, P; Ay-Zog, D (Schweizerbart, 2006-01-01) Daphnia, freshwater crustaceans that graze algae, often rely on predatory chemical cues termed kairomones as signals for predator-avoidance. Using laboratory bioassays, we studied how planktonic bacteria may modify kairomone activity. We measured the amplitude of diel vertical migration (DVM) of Daphnia pulex DE GEER among treatments with different amounts of bacteria. We used temperature incubation to increase bacterial densities and filtration to reduce abundance. Daphnids exposed to fish cue (F) and filt...
Energy-based top-down and bottom-up relationships between fish community energy demand or production and phytoplankton across lakes at a continental scale Bartrons, Mireia; Mehner, Thomas; Argillier, Christine; Beklioğlu, Meryem; Blabolil, Petr; Hesthagen, Trygve; Sweden, Kerstin Holmgren; Jeppesen, Erik; Krause, Teet; Podgornik, Samo; Volta, Pietro; Winfield, Ian J.; Brucet, Sandra (Wiley, 2020-04-01) Fish community feeding and production rates may differ between lakes despite similar fish biomass levels because of differences in size structure and local temperature. Therefore, across-lake comparisons of the strength and direction of top-down and bottom-up fish-phytoplankton relationships should consider these factors. We used the metabolic theory of ecology to calculate size- and temperature-corrected community energy demand (CEDom) and community production (CP) of omnivorous fishes in 227 European lake...
Interaction between non-native predatory fishes and native galaxiids (Pisces: Galaxiidae) shapes food web structure in Tasmanian lakes Vidal, Nicolas; Trochine, Carolina; Amsinck, Susanne L.; Barmuta, Leon A.; Christoffersen, Kirsten S.; Ventura, Marc; Buchaca, Teresa; Landkildehus, Frank; Hardie, Scott A.; Meerhoff, Mariana; Jeppesen, Erik (Informa UK Limited, 2020-04-01) Non-native fish invasions threaten native fauna and ecosystem functioning, not least in isolated island lakes. In Tasmania, where the native fish are mostly galaxiids, 9 non-native freshwater fish species have been introduced over the past 150 years, with uncertain ecological outcomes. We evaluated the effects of non-native predatory fishes (NNPF) and various environmental and biological variables on the trophic niche of native fish (galaxiids) and potential cascading effects. We analysed Layman's food web ...
