Preservation experiments revealed that chloroform (99.8%) is an effective preservative.
To examine the possibility of soft-bodied microfossil preservation, experiments were conducted on the process of the soft-bodied fossilization.
He died of an infection he picked up from a chicken he was using in a food-preservation experiment.
It has been suggested that a mucus trail produced by the organism may have assisted its preservation, but experiments suggest that mucus disintegrates too easily to play a role in binding sediment together.
In another experiment, preservation of cone function was assessed by ERG recording.
Out of 53 samples, 11 samples were eliminated because of (1) the lack of RNA preservation in repeated experiments evidenced by β-actin expression in tumour tissues, (2) no HOXB13 expression in normal matching tissues, leading us to suspect that origin of tumours are anatomically HOXB13-free region, especially in distal colon.
Since 1994, when this National Historic Landmark -- about twice the size of Central Park -- became a national park, a novel and much-debated experiment in preservation and park planning has been under way at the 200-year-old military garrison.
In our experiment, the preservation of the B2 branch at low frequency during more than 400 generations could result from a frequency-dependent selection.
Another probabilistic approach addresses the trade-off between identity preservation and long-term experiments [24].
In two out of the first three experiments, the preservation of rice (excluding husk but including spikelet bases) compared to the millets was higher, though it was especially high when the rice had been in the fire for the longest duration of the experiment (Ex1).
Long-term experimental studies aimed at discerning the evolutionary trajectories open to newly-formed hybrids under different types of selection are lacking, a knowledge gap due in part to the scarcity of hybrid eukaryotes that have the short generation time and ease of preservation needed to undertake experiments lasting hundreds of generations.
