“…The reproductive suppression events observed during the experiment encourages us to discuss temperature‐related deterioration in food quality as a factor potentially shaping population growth responses of D. lumholtzi . It is well known that cyanobacterial filaments have poor nutritional quality because of deficiency in sterols and fatty acids (Von Elert, Martin‐Creuzburg, & Le Coz, ), and temperature elevation can exacerbate their low quality, as it reduces the P:C ratio in cyanobacterial cells (Li et al, ). Temperature elevation also reduces the nutritional value of green microalgae, especially through reduction of PUFA content in microalgal cells, which substantially reduces Daphnia fitness (Sikora, Dawidowicz, & Von Elert, ).…”

Exotic cladoceran Daphnia lumholtzi is a highly invasive species in the north and south American continents and can potentially also invade European freshwaters and outcompete native Daphnia populations. However, European waterbodies are frequently dominated by less edible filamentous cyanobacteria including also invaders such as Raphidiopsis raciborskii, which might affect the fitness of D. lumholtzi. Furthermore, temperature may influence the sensitivity of D. lumholtzi to R. raciborskii filaments. In this study, we determined whether the presence of R. raciborskii could obstruct the invasion of Europe by D. lumholtzi, through reducing its fitness, and whether this depends on temperature. We compared the population growth rate (r) and the somatic growth rate of D. lumholtzi maintained at two temperatures (20 or 26°C) and fed with two diets: green microalgae alone or green microalgae mixed with filaments of R. raciborskii. Three clones of D. lumholtzi were used to evaluate potential variation in response to the treatments among different clones. At 20°C, the population growth rate of D. lumholtzi fed with cyanobacterial filaments declined sharply. This reduction was caused by increased egg abortion, egg degeneration, and mortality of newborn daphnids. At 26°C, R. raciborskii lost its harmful effect on the population growth of D. lumholtzi. The presence of cyanobacteria did reduce the somatic growth rate of D. lumholtzi at both temperatures and in all three clones except for one that had a similar somatic growth rate on both diets at 26°C. The presence of filamentous cyanobacteria does affect growth in D. lumholtzi and may thereby substantially reduce its invasive potential, but only at lower temperatures. Therefore, the presence of filamentous cyanobacteria may not present an obstacle to the invasion of Europe by D. lumholtzi in a warmer future climate.

A Chlorella sp.-Cupriavidus necator (C. necator) consortium was artificially established for phenol degradation. The synergistic relationship between Chlorella sp. and C. necator was initially demonstrated, and then the effects of Chlorella sp./C. necator inoculation ratio, light intensity, temperature and pH on the performance of this consortium were systematically evaluated and optimized. The optimal conditions for phenol degradation were as follows: a Chlorella sp./C. necator inoculation ratio of 1:1, a light intensity of 110 µmol m -2 s -1 , a temperature in the range of 25-32 ℃ and a pH in the range of 5.5-7.5. Under optimal conditions, this consortium could degrade phenol with a maximum concentration of 1200 mg L -1 within 60 h. Comparative transcriptomic analysis was conducted to discuss the symbiosis mechanism of this consortium subject to high phenol concentrations. The up-regulation of genes involved in photosynthesis and carbon fixation of Chlorella sp. demonstrated the CO2 and O2 exchange between Chlorella sp. and C. necator, which, we suggest, may be the main reason for their mutual promotion of growth and phenol degradation.

“…Still, this mechanism has not yet been properly studied [15]. Most studies report on significant synchronization with a certain time lag of variability of phytoplankton and zooplankton biomass (for example, [16]). In a purpose reseach [17], a positive correlation between these characteristics of hydrobionts was obtained for the George Bank Bay ecosystem.…”

The objective of the work is to simulate a long-term process of eutrophication based on the concept of the aquatic ecosystem instability. A model assessment of qualitative effects associated with the development of a succession of aquatic communities during degradation of the ecosystem requires expanding the boundaries of the conventional approach. This raises the question of changing the structure of the reservoir ecosystem model. An idea of the Darwin's principle of natural selection is the key point for assessing changes in the biodiversity structure. The problem was solved through consideration of changes in physiological activities of hydrobionts. The study based on biogeochemical cycles modelling revealed the change in the structure of the ecosystem. Also the novelty of the work is in the implementation of the method for structural-dynamic modelling to assess the trend of long-term eutrophication of the Novosibirsk reservoir, the largest in Western Siberia.
