Sentences with phrase «urchin larvae»

The responses of sea urchin larvae to ocean acidification may be influenced by habitat type, and may also be species specific, leading to the suggestion that some species are more robust to ocean change stressors than others (i.e. «winners versus losers»)[68].

We addressed questions on the vulnerability of sea urchin larvae to changes in ocean conditions in species from a range of environments (intertidal / subtidal) and latitudes (tropical to polar).

You will then carry out a virtual lab — the Virtual Urchin — to study the effect of a more acidic seawater pH on sea urchin larvae.

The research found that sea urchin larvae were not impacted by levels of increasing «acidification» of sea water that some have predicted will represent ocean waters 100 + years from now.

In addition, they indicate that «a lack of developmental deformities at early stages for pCO2 ~ 1000 ppm has been previously reported for this species...» And they say «there are even reports that survival is increased in this species and its congener S. droebachiensis under some low pH conditions...»... conclude, that «the effects of small magnitude in these urchin larvae are indicative of a potential resilience to near - future levels of ocean acidification.»»

Gretchen Hofmann who studies sea urchin larvae calls this the «double jeopardy» problem, where larvae can still make their skeletal rods, but doing so comes at the cost of being able to cope with thermal stress.

The stunting effect of a high CO2 ocean on calcification and development in sea urchin larvae, a synthesis from the tropics to the poles

Dr. Rebecca Vega Thurber received her doctorate in 2005 from Stanford University where she studied developmental cell signaling pathways in sea urchin larvae.

To mimic such conditions, Pespeni placed half of her urchin larvae in water with carbon dioxide levels that match current ocean conditions.

To find out how well evolution can keep pace with the changing environment, Melissa Pespeni at Indiana University in Bloomington and her colleagues reared purple sea urchin larvae in water of normal or raised acidity.

«Urchin larvae from females exposed to low pH conditions had more genes turned on and were better prepared to handle stress.
