<｜begin▁of▁sentence｜>### Instruction:
As a silviculturist who manages and studies forests, trees, and timberlands to promote sustainable forestry practices, conservation, and ecosystem management, imagine you are tasked with analyzing a network of interconnected forest areas. The network represents relationships among different parts of the forest ecosystem, with edges indicating interactions between areas.

Now, given a specific network represented by the edge set [(0, 1), (1, 2), (2, 3), (3, 4), (4, 0), (2, 5), (5, 6), (6, 2)], you are interested in identifying and understanding potential key points of connection or separation within this forest ecosystem. To achieve this, you decide to utilize the 'minimum_size_separators' function provided by relevant tools in forest network analysis.

Your goal is to calculate and list all the separator vertex sets of minimum size within the forest network. By identifying these specific vertex sets, you can gain valuable insights into the critical points where the network structure could be most affected or fragmented if these vertices were removed, aiding in making informed decisions for sustainable forest management and ecosystem conservation.
### Response:
from igraph import Graph

# Define your graph
edges = [(0, 1), (1, 2), (2, 3), (3, 4), (4, 0), (2, 5), (5, 6), (6, 2)]
g = Graph(edges)

# Calculate the minimum size separators
separators = g.minimum_size_separators()
print('Minimum size separators:', separators)
