Long - term microcosm experiments are providing insights into potential outcomes with regard to seasonal change and
acclimatization adaptation [85,111,112].
Not exact matches
Acclimatization refers to physiological changes whereas
adaptation refers to genetic changes.
Adaptation and
acclimatization to ocean acidification in marine ectotherms: an in situ transplant experiment with polychaetes at a shallow CO2 vent system
«Both
acclimatization and
adaptation will shift sensitivity thresholds but the capacity and limits of species to acclimatize or adapt remain largely unknown» Pg 23
Natural spatial and temporal variability in the pH / pCO2 conditions experienced by marine populations provide the potential for different levels of
adaptation (genetic) and
acclimatization (phenotypic) to decreased pH and elevated pCO2, emphasizing the importance of understanding physiological variation existing along natural environmental gradients (macrophysiology) in understanding global change impacts [29].
The majority of these studies report short - term (days, weeks or a few months, see [10]-RRB- «shock» responses that do not incorporate the longer - term potential for species gradual
acclimatization (i.e. respond via phenotypic plasticity, see [11]-RRB- or
adaptation (the selection of extant genetic variation that moves the average phenotype of a population towards the fitness peak).
They show that long - term
acclimatization or
adaptation to warm and acidified conditions could change or even reverse the negative calcification responses observed in short - term studies, and thus alter feedbacks to the global carbon cycle.
