Enhancing Thermal Resilience in Delta Smelt: A Comparative Study of Temperature Regimes During Embryonic Development
This dataset contains larval heart rate measurements from hatchery-reared Delta Smelt (Hypomesus transpacificus), a critically endangered species native to the San Francisco Bay-Delta. The data were collected at the UC Davis Fish Conservation Physiology Lab as part of an experiment investigating how early-life exposure to different thermal environments influences cardiac performance and thermal tolerance. Embryos were incubated under three temperature regimes: constant (16°C), controlled diurnal fluctuation (16–20°C), and natural outdoor pond conditions with variable temperatures. Larval heart rate was recorded during an acute thermal ramp using a microscope-mounted camera system to track cardiac activity in real time. These data were collected to assess the physiological plasticity of Delta Smelt and to inform conservation hatchery strategies aimed at enhancing resilience to thermal stress.

Transcriptional regulation underlying the temperature response of embryonic development rate in the winter moth
<p>Climate change will strongly affect the developmental timing of insects, as their development rate largely depends on ambient temperature. However, we know little about the genetic mechanisms underlying the temperature sensitivity of embryonic development in insects. We investigated embryonic development rate in the winter moth (<em>Operophtera brumata</em>), a species with egg dormancy that has been under selection due to climate change. We used RNAseq to investigate which genes are involved in the regulation of winter moth embryonic development rate in response to temperature. Over the course of development, we sampled eggs before and after an experimental change in ambient temperature, including two early development weeks when the temperature sensitivity of eggs is low and two late development weeks when temperature sensitivity is high. We found temperature-responsive genes that responded in a similar way across development, as well as genes with a temperature response specific to a particular development week. Moreover, we identified genes whose temperature effect size changed around the switch in temperature sensitivity of development rate. Interesting candidate genes for regulating the temperature sensitivity of egg development rate included genes involved in histone modification, hormonal signalling, nervous system development, and circadian clock genes. In conclusion, the diverse sets of temperature-responsive genes we found here indicate that there are many potential targets of selection to change the temperature sensitivity of embryonic development rate. Identifying for which of these genes there is genetic variation in wild insect populations will give insight into their adaptive potential in the face of climate change.</p>
