How are there enough fish being caught to feed all of the other people who ordered a salmon sushi roll today? Will there be enough tomorrow as well? Despite pondering these questions for a few seconds, you probably shrug it off and delve into your delicious meal, not to think of it again until the next time you arrive at a sushi restaurant.
Understanding species interactions and population dynamics are important for tracking the success and spread of threatened and endangered species. But how can scientists accurately track these data for species that look the same and cannot be identified via visual comparisons of two individuals? The answer may lie in the realm of conservation genetics and genomics. In addition to being able to provide species-level identification (and even individual-level identification), this field obtains and analyzes organisms’ genetic material to gain insight into population functions. Data obtained from genetic material can shed light on how isolated populations are from one another, how large populations are, and how populations are related to each other in time and space.
Highly prized as delicacies, oysters are farmed all over the world. In the US, they account for the highest volume of marine shellfish production, amounting to a total of 36.5 million pounds in 2018. However, as seawater temperatures rise due to global warming, oyster aquaculture will face obstacles and will likely need to reshape its practices to continue its success.
