Ever wonder about the jargon scientist use? In our Word Wednesday series, we explain the meaning behind scientific terms and concepts important in ACER research.
A few weeks ago we discussed food webs and introduced the topic of top-down and bottom-up control. Today we are going to dig a little deeper into those processes and look at some examples in the marine environment.
We have chatted before about food chains and food webs and you may recall learning about the process of photosynthesis. When scientists consider ecosystems, you will more often hear the term primary production. What is the link between these terms? Are they the same thing? Why do scientists measure it?
Just like a healthy garden, a healthy ocean floor has worms and other animals that move through, ingest and affect the characteristics of the ocean floor sediment. This process is known as bioturbation. In this installment of Word Wednesday, we will explore this process of bioturbation, who are the key players, what they do and why this process is important.
In an earlier post we talked about ACER’s focus on biodiversity. Scientists look at biodiversity at several scales such as the level of the ecosystem, or the species level and even the level of the individual organism. With modern gene sequencing technology, scientists are able to look at the variation in genes between individuals. We call this genetic diversity (biodiversity – at the level of molecules!). Let’s explore it in more detail.
Sweet or sour? While you might think we’re talking about candy, this week’s Word Wednesday is actually about crude oil. Join us as we explore the sweet and sour properties of crude oil as well as chemical dispersants that were used in the clean-up of the Deepwater Horizon oil spill.
