Incipient lethal
Webupper and lower incipient lethal temperatures change with variations in acclimation temperature is different for different species. The upper incipient lethal of the roach (Cocking, 1959), and goldfish (Fry et al., 1942) increases about 1 C" for each 3 C" rise in acclimation temperature but that of the speckled trout increases at WebMay 6, 2024 · The upper incipient lethal temperature (50% lethal water temperature) was estimated to be 31.8 °C, higher than the maximum sea surface temperature in the field (approximately 29 °C). The critical thermal maximum was 34.8 °C, whereas it was 36.1 °C when juveniles were preliminarily acclimated to 31 °C for 24 h.

WebThe most critical (sensitive) life stage of a particular invertebrate is its first instar which has an incipient LC50 of 10 μg L-1 and a NOEC of 5 μg L-1 for growth during toxicant X exposure. Can a viable population of this invertebrate be maintained below an effluent with a maximum concentration of 5 μg L-1 for this toxicant? ... Lethality Tests WebNov 9, 2024 · Ranges between the upper and lower incipient lethal temperatures increased during development from yolk-sac larvae to juveniles, especially in response to cold shock, indicating that later developmental stages in this species are more tolerant of temperature fluctuations. However, thermal tolerance is not solely determined by life stage.

WebChronic or incipient upper lethal thermal limits involve continuous exposure of the target organism to constant lethal temperatures for a time period long enough to achieve significant mortality. WebAfter 96 hr of exposure, the incipient lethal concentration was calculated to be 0.118 ± 0.04 μM cadmium. At concentrations three orders of magnitude higher than the incipient lethal concentration, cadmium was incorporated into both the cellular cytoplasm and the cell's polyphosphate bodies. Cadmium also caused the polyphosphate bodies to ...
