The Marine Organism
This is the scientific name for the Antarctic Krill
Euphausia superba
A surplus of anthropogenic carbon dioxide emissions has led to these 3 general things impacting the Antarctic Krill
Temperature rise, sea ice decline, and ocean acidification
This species is a major food source for many marine organisms, their organic matter drives food webs in the deep ocean, they feed on phytoplankton, and act as a carbon sink
Antarctic Krill
This is needed in order to find out the behavioral and physiological responses of krill to environmental stressors such as ocean acidification, sea ice decline, and rising sea temperatures
More research
They are found in these Antarctic waters
The Indian and Southern Oceans
This is when the ocean continues to absorb CO2, leading to an effect in the embryonic development of krill and can compromise their growth, fitness, behavior, and reproduction, ultimately leading to a decline in population
Ocean acidification
A change in the distribution of Antarctic Krill based on sea ice abundance can affect these organisms from finding food
Finding a way to prevent the decline in this can help multiple organisms, not just the Antarctic Krill
Sea ice
They utilize this behavior as both a defense mechanism, and as a way to follow their feeding habits
Swarming
This provides multiple benefits for krill but with a decline in such due to climate change, their habitat becomes widely distributed, negatively impacting their reproductive success and survival
Sea ice
Changes in this can lead to an effect on foraging, breeding success, and population size of krill-dependent predators
Krill biomass
Finding the range of ____ in which antarctic krill can withstand in order to perform their physiological processes throughout their life cycle, is needed to help researchers understand how best to prevent this range from exceeding
Ocean temperatures
Since they have a wide range of habitats both near the surface and at various depths in the ocean, they utilize this kind of migration which helps transport essential nutrients and influences the carbon sink and other marine organisms
Vertical Migration
Increases in this can lead to changes within the phytoplankton community structure, which would alter primary productivity and the dynamics/structure of the food web, impacting Krill which is a major consumer of phytoplankton
Water temperature
Krill produce this which dramatically impacts their surrounding ecology/biology as it helps fluctuate nutrients in the oceans, and provides a favorable and more efficient carbon sink
Fast sinking fecal pellets that are carbon rich
Finding the level of ____ is needed to find out when the embryonic development of krill starts to become affected and when their growth, fitness, behavior, and reproduction starts to become compromised
Acidity/pH
