Gradual warming

Gradual warming decreases adult body size in D. magna.

“Reciprocal transplants revealed a persistent reduction in adult body size of warming-line offspring, regardless of rearing environment”

Model organismsWarming-line offspring in reciprocal transplants, regardless of rearing environment

Gradual warming increases growth rate in D. magna.

“Warming populations matured earlier, grew faster, and initially reproduced more than controls”

Model organismsCompared with constant temperature at 26 °C; growth rate remained largely plastic in reciprocal transplants+1 °C every 4–6 generations, up to 32 °C30 generations

Gradual warming is associated with fecundity in D. magna.

“initially reproduced more than controls, but suffered shorter lifespans and lost their reproductive advantage near 30 °C”

Model organismsInitial reproductive advantage over controls disappeared near 30 °C+1 °C every 4–6 generations, up to 32 °C30 generations
