It's Weird How Many Species Live At Both Poles

The video explores the concept of bipolar species, organisms found at both poles, and their distribution. It discusses the 2009 marine life survey revealing 235 bipolar species and subsequent genetic studies that question their classification. The video examines gene flow in amphipods and plant dispersal hypotheses, including mountain hopping and long-distance dispersal by shore birds. It highlights the role of climate change in affecting deep-sea currents and the need for further research to understand these species' distribution and genetic makeup.

What role do long-distance shorebirds play in the dispersal of bipolar plant species?

What implications does climate change have on the distribution of deep-sea organisms?

What challenges do researchers face in understanding the gene pool sharing among polar populations?
