of the network or the giant component. Figure 2 shows the gi-
ant component. The color of the nodes represent communities
as detected by the Louvain method. We obtained a modularity
score of 0.913 (out of a possible range of 0 to 1). This high
modularity score indicates that the detected communities are
much more tightly connected by technical dependencies than
would appear in a random graph.
There were 43 ecosystems identified in this network. Nodes
are sized according to their authority to display the nodes that
are more prominent in each ecosystem. When a node has a
high number of cross-reference relationships pointing to it, it
has a high authority value [18]. Table I shows the most well-
connected project node (highest Authority value) in each of
the ecosystems.
C. Properties of GitHub Ecosystems
Ecosystems revolve around one central project. As depicted
in Figure 2, each ecosystem appears to revolve around one
main project. In Table I, the most well-connected project
node in each ecosystem is listed along with a description

Gender diversity positively
affects productivity, but.
does not influence turnover.
Tenure diversity positively
affects both productivity
and turnover.
