Genetic mapping in the grapevine has relied almost exclusively on linkage mapping, which is time-consuming because of the grapevine's long generation time (generally 3 years).
However, the low overall heritability of coral host traits, along with the corals' long generation time, raise concern about the timely adaptation of the coral-algal symbiosis in the face of continued rapid climate warming.
Furthermore, this seems as a long generation time for a duck.
In addition, the relatively long generation time of the aerosol cloud (approximately 1.5 s) facilitates co-ordination of inhalation and actuation – a major problem with pMDIs.
But fur seals are particularly vulnerable to climate change as they inhabit a region with fast-changing temperatures, and their relatively long generation time limits their ability to adapt evolutionarily.
Yet a new study suggests that our long generation time evolved fairly recently.
Due to the long generation time of orchids, transformation may reduce the time needed to produce a desirable trait.
Evolution moves at a tectonic pace – almost infinitely powerful, but almost infinitely slow (particularly for species, like humans, that already have a long generation time).
The great hammerhead is extremely vulnerable to overfishing due to its low overall abundance and long generation time.
"Due to their long generation time and the current greater speed of global warming, it seems unlikely that polar bear will be able to adapt to the current warming trend in the Arctic," the IUCN explains.
We propose that the very long generation time of the host tree may have had a major stabilizing effect.
