Procedures
The three organisms tested.
What are Hermit Crabs, Periwinkle Snails, and Mussels?
Thermal history over this time period significantly influenced thermal sensitivity the most in this experiment.
What is one day?
This species showed the highest overall thermal sensitivity.
What are hermit crabs?
Periwinkle snails have been observed regulating their body temperature by 3-5 degrees C through this mechanism.
What is withdrawing their foot into their shell?
The statistical procedure used to determine the main factors contributing to variations in thermal history.
What is Principal Component Analysis (PCA)?
During this month, the tide pool temperatures were found to be at their lowest relative to the other two months recorded.
What is March?
What is being sessile?
The location of the field site where the researchers collected tide pool invertebrates for this study.
What is Sitka, Alaska?
The three months during which the organisms were tested.
What are March, July, and September?
In cooler months, individuals from warmer, more variable pools showed this trend.
What is higher thermal sensitivity?
This organism showed metabolic depression at the highest experimental temperature.
Although they showed lower sensitivity, the mussels studied in this article may be more susceptible to mortality from long-term warming once they pass this.
What is a critical threshold (or upper thermal limit)?
Number of tide pools visited per day.
What is 8?
Generally, thermal sensitivity was highest across all three types of organisms during this month.
What is September?
This organism had the highest among-individual variation.
What are hermit crabs?
DAILY DOUBLE!!!
This is the scientific name of the hermit crabs used in this study.
What is Pagurus hirsutiusculus
