More on Biology & Climate Change (Paty Matrai)

Dr. Paty Matrai discusses the size of organisms in polar regions, particularly in the Arctic. She explains that colder waters and a lack of predators contribute to larger sizes of species like sea stars. In the Arctic, there is a discontinuity in the timing of prime production by ice algae. When the ice melts, the fallen algae reaches the sediments, creating a food source for benthic fauna such as clams and seals. Dr. Matrai highlights the benthic-pelagic communication and self-basing interactions that occur in this ecosystem. She raises questions about the impact of earlier warming and the arrival of zooplankton from the south on the availability of food sources. Additionally, she mentions the discovery of green floc on the Arctic seafloor, which were observed by German scientists using cameras. These flocs are believed to be related to the thinning ice, early snowmelt, and increased light availability for growth. The scientists plan to conduct further research on this phenomenon to understand its implications for biological connections between ice and sediments in the Arctic.
