Such a change of sex structure was observed in the mussel <i>Mytilus galloprovincialis</i> at the Black Sea coast of Crimea, where the sex ratio shifted toward male mussels. This pattern may be caused by the sex inversion in females, higher female mortality, and their falling off to the bottom. Experiments with cultivated mussels <i>M. galloprovincialis</i> were conducted in natural and laboratory conditions to identify the reasons for this phenomenon. The inversion of the mussel sex proceeds in one direction: from females to males. The change of sex occurs under the influence of environmental factors during the post-spawning restructuring of gonads. Such factors can be adverse hydrological and hydrochemical conditions; environmental pollution; food availability; age and size of mollusks. The sex inversion of mussels in the polluted water area was 20% higher than in the relatively clean water of the mussel farm. The higher mortality of mussel females (69%) in the polluted area as compared to the clean one (19%) was also observed. In a laboratory experiment, the mortality level of females was 34% higher than that of males. The sex ratio on the farm, 1:2.9 (♀:♂), and on the bottom under the farm, 2.6:1 (♀:♂), was found, and the predominance of females at the bottom under the farm was noted. A bias in the sex structure in one direction—from females to males—can have economic implications in aquaculture as well as ecological significance.

As only early juvenile instars of <i>D. pulex</i> are vulnerable to predation by <i>Chaoborus</i> sp., increased developmental time extends the time span that <i>D. pulex</i> is in the vulnerable size, and thus increases the risk of being preyed upon.

To test this, we created a gradient of growth conditions for <i>Daphnia</i> that would cause an increase in developmental time by means of decreasing the temperature or increasing the proportion of dietary cyanobacteria in separate experiments. We determined the body size during the juvenile instars and calculated the time spent in vulnerable instars. Correlations of neckteeth induction to times spent in vulnerable instars were significant for the data set of the temperature experiment and the combined data set, but not for the data set of the cyanobacteria experiment.

Our study characterized environmental factors related to N₂ fixation in Brazilian tropical reservoirs with contrasting trophic states, and defined quantitative thresholds for water chemistry and physical characteristics that stimulated N₂ fixation. We used field assays with ¹⁵N for estimating N₂ fixation rates by phytoplankton. The highest rates normalized by chlorophyll-<i>a</i> (maximum of 143 × 10⁻⁴ μg-N μg-Chl-<i>a</i>⁻¹ h⁻¹) coincided with eutrophic conditions and presence of diazotrophs. Receiver operating characteristic (ROC) analysis provided significant thresholds for water temperature (≥22°C), soluble reactive phosphorus (SRP) (≥3.0 μg-P L⁻¹), total phosphorus (TP) (≥20.5 μg-P L⁻¹), DIN:SRP (≤487) and DIN:TP (≤82) molar ratios, chlorophyll-<i>a</i> (≥12 μg L⁻¹), and total suspended solids (≥4 mg L⁻¹). Censored regressions confirmed that temperature, chlorophyll-<i>a</i>, and phosphorus were important predictors of N₂ fixation rates. In general, the N₂ fixation rates determined in this study were lower than those found for temperate reservoirs. However, the temperature threshold of 22°C or above, identified in our analysis, suggests that phytoplankton have the potential to fix N₂ throughout the year in tropical reservoirs. Our results suggested that phosphorus is the main nutrient controlling the rates of N₂ fixation when N₂-fixing cyanobacteria were present.
