“…Temperature and salinity are important environmental factors affecting the survival of marine benthic organisms, and increasing temperatures and decreasing salinity can act as dominant physical stressors [9]. The reported effects of an increase in temperature include changes in growth [10,11], behavior [12,13], metabolism [14,15], and mortality [12,16]. Salinity effects include abnormal endogenous rhythms [17], changes in behavior [18][19][20], decreased condition index [21,22], and increased mortality [23].…”

This article investigates the response of the Manila clam Venerupis philippinarum to possible temperature and salinity changes in a holding facility. First, clams are exposed to four temperatures for 15 days. Valve closure and survival of clams exposed to seawater at 18 °C are higher than those exposed to seawater at 24 °C. Second, clams are exposed to six salinities for 15 days. Survival of clams exposed to two salinity fluctuation conditions (24–30 and 27–24 psu) is lower than that of clams exposed to constant 30 psu conditions. Valve closures of clams exposed to constant low salinity conditions (24 psu) and two salinity fluctuation conditions (24–30 and 27–24 psu) are higher than those exposed to constant 30 psu conditions. Lastly, clams are exposed to two different temperatures and three different salinities conditions for eight days. Valve closure and survival decreased significantly under the combination of 24 °C and 18 psu. These results suggest that an increase in temperature or a wider range of salinity fluctuations are detrimental to the survival of the Manila clam. The synergistic effect of temperature and salinity stressors may decrease the survival period of clams compared to the effect of a single stressor.

“…Embryos of most species develop outside the mother and many have evolved so that they can adopt to fairly wide temperature ranges. Canonically, it has been observed that embryos develop faster with higher temperature (Khokha et al, 2002;Kuntz and Eisen, 2014;Sin et al, 2019). However, some proteins decrease their concentration and presumably their activity in the liquid-phase separated nucleolus with increasing temperature (Falahati and Wieschaus, 2017).…”

The famous Arrhenius equation is well motivated to describe the temperature dependence of chemical reactions but has also been used for complicated biological processes. Here, we evaluate how well the simple Arrhenius equation predicts complex multistep biological processes, using frog and fruit fly embryogenesis as two canonical models. We find the Arrhenius equation provides a good approximation for the temperature dependence of embryogenesis, even though individual developmental stages scale differently with temperature. At low and high temperatures, however, we observed significant departures from idealized Arrhenius Law behavior. When we model multistep reactions of idealized chemical networks we are unable to generate comparable deviations from linearity. In contrast, we find the single enzyme GAPDH shows non-linearity in the Arrhenius plot similar to our observations of embryonic development. Thus, we find that complex embryonic development can be well approximated by the simple Arrhenius Law and propose that the observed departure from this law results primarily from non-idealized individual steps rather than the complexity of the system.
