Dosidicus gigas
It is also known as the Jumbo or Jumbo Flying Squid.
What is the Humboldt Squid, or Dosidicus gigas?
The aspect of climate change that results in excessive heat absorption by the oceans, ultimately leading to increase in seawater temperature.
What is the enhanced greenhouse effect?
The term describing the expansion of oxygen minimum zones.
What is shoaling?
The element of climate change inducing increases in Dosidicus gigas populations.
What is ocean warming?
Future insight into mechanisms of operating under these conditions can yield knowledge of how climate change benefits Dosidicus gigas.
What are hypoxic conditions?
This term describes the daily migration pattern of Dosidicus gigas in the water column, in which it moves down in the water column during the day and back up at night.
What is a diel vertical migration?
It is the outcome of increasing seawater temperature on dissolved oxygen levels.
What is a decrease in dissolved oxygen?
The driver of oxygen minimum zone expansion over the last 50 years.
What is climate change?
Ocean warming gives Dosidicus gigas an advantage in this, which they do to obtain energy during the day.
What is foraging?
An experimental future direction that can provide predictions about past and future impacts of climate change on Dosidicus gigas.
What is the manipulation of living conditions?
What is currently happening to the habitat of Dosidicus gigas, in which it is present farther north and in farther numbers than ever before.
What is the habitat range expansion?
The vertical separation of waters due to a temperature gradient, resulting in less water mixing.
What is water stratification?
The area of the water column that is compressed due to oxygen minimum zone shoaling.
What is the epipelagic zone?
Ocean warming gives Dosidicus gigas both an advantage in and vulnerability to this.
What is predation?
The mechanisms to be investigated regarding survival of Dosidicus gigas in oxygen minimum environments.
What are metabolic suppression and halting of transcription and translation?
This is the main regulatory factor in the daytime distribution of Dosidicus gigas.
What are sub-critical oxygen levels?
A process involving transfer of oxygen from the air into the water column that is decreasing due to increasing seawater temperature.
What is atmospheric mixing?
The two main changes to oxygen minimum zones as a result of ocean warming.
What are shoaling and intensification?
Competition is lessened for Dosidicus gigas due to this change.
What is the compaction of the epipelagic zone?
The two abiotic factors that may be critical to manipulate in order to identify optimal conditions for survival of Dosidicus gigas.
What are temperature and dissolved oxygen levels?
Adaptations such as these allow Dosidicus gigas to function in hypoxic environments. (Name 2)
What are metabolic suppression, lower rapid jetting, augmented oxygen binding, anaerobic respiration, and halting of transcription and translation?
These are created as a result of less dissolved oxygen in the ocean.
What are oxygen minimum zones?
Where restriction of epipelagic boundaries has been observed.
Where are major eastern boundary current oxygen minimum zones?
Oxygen minimum shoaling is resulting in this change in Dosidicus gigas distribution.
What is the habitat range expansion?
Two major areas of unexplored research regarding climate change’s impact on Dosidicus gigas.
What are optimal conditions and hypoxic living mechanisms?
